Facebook Inc introduced free video calling in its Messenger phone app on Monday as the company seeks to transform its mobile messaging service into a full-featured platform with the same reach as its 1.4 billion user social network.
Messenger, with more than 600 million users, now has a video icon at the top right corner of its screen. Earlier this year, Messenger launched voice and video calling between computers. (bit.ly/1KorYLD)
Messenger competes with Microsoft Corp's Skype, Apple Inc's FaceTime and Google Inc's Hangouts, all of which allow video calls between mobile devices or computers.
At Facebook's annual developer conference in March, Chief Executive Mark Zuckerburg said the social network would introduce myriad features within Messenger. For example, users can also send money to friends within the app. Facebook also unveiled a platform that enables developers to easily create apps that function within Messenger.
"Adding (video calling) to Messenger instead of the main Facebook app maybe ties in to Messenger's mission where it's a real core person-to-person app," said Brian Blau, research director at Gartner Inc, a U.S. technology research and advisory firm. "Now they're really enticing people with more features."
Video calling is available on devices using Apple's iOS and Google's Android mobile operating systems in Belgium, Canada, Croatia, Denmark, France, Greece, Ireland, Laos, Lithuania, Mexico, Nigeria, Norway, Oman, Poland, Portugal, the United Kingdom, the United States and Uruguay. Facebook said additional regions will be added in the next few months.

Inclusive classrooms don't necessarily increase friendships for children with disabilities

 

Dropping off a child at kindergarten for the first time can be one of the most memorable yet terrifying experiences of parenthood. Among the many concerns parents face is the worry whether your child will make friends -- a key factor, research shows, in reducing anxiety, depression and the likelihood of being bullied.
For parents of children with disabilities, the concern is even greater as four-out-of-10 of their children will enter kindergarten without the social skills necessary to develop close friendships. The response from schools has been to create inclusive classrooms, where a significant number of students with disabilities now receive the majority of their education and are believed to have a better chance at developing close relationships with peers.
But after studying six inclusive classrooms, Lori Erbrederis Meyer, assistant professor of early childhood and early childhood special education at the University of Vermont, has found that inclusive classrooms with disability awareness curricula alone do not increase friendships for students with disabilities. Her study, forthcoming in Topics in Early Childhood Special Education and available now via the journal's OnlineFirst service, also showed that having a best friend helps children with high rates of problem behaviors and low rates of social skills still gain peer acceptance.

"The fact that about 40 percent of young children with disabilities will enter kindergarten without age-appropriate social relationship skills is striking, because these skills help them form friendships, which in turn supports smoother transitions in kindergarten and may prevent later peer victimization," says Meyer, a former inclusive early childhood teacher herself. "We found that inclusion in and of itself does not equate to increased acceptance, classroom membership or peer relationships. This research emphasizes the importance of individualizing class-wide programs based on children's support needs."

Investigating the impact of a disability-focused curriculum

In her article, "Impact of an Affective Intervention on the Friendships of Kindergarteners with Disabilities," Meyer investigates a disability awareness curriculum's impact on the development of close friendships among 26 kindergarteners with disabilities enrolled in six inclusive classrooms. She also looked into whether the presence of at least one best friendship mediated the relationship between children's social skills/problem behaviors and peer acceptance.

The study compared the results of two groups, each containing students with and without disabilities. In one group, classroom teachers implemented the "Special Friends" program, a curriculum designed to increase children's positive attitudes about disabilities. In the other, teachers implemented a curriculum with a focus on science. Each program included class-wide shared book reading, mixed-ability cooperative learning groups where students engaged in play-based activities with one another, and a lending library, allowing children to bring books read at school home to read with their families.

The Special Friends program read books with a focus on disability-related themes, with teachers discussing the book's plot, connections between the children and the characters in the books, understanding of disabilities and disability-specific vocabulary. Teachers using the science program led shared book reading in a very similar way, except that they read books with science-related content.

"Contrary to our hypothesis that the number of best friendships would increase in the Special Friends program, we found a significant increase in the number of best friendships for children with disabilities participating in the science program," Meyer says.

There was, the study notes, one important difference between the cooperative learning groups' activities in Special Friends versus the science curriculum. While the former encouraged open-ended, dramatic play -- like pretending to run a restaurant -- the latter worked on project-based activities that had clearly defined outcomes -- like working together to build a bird's nest.

"Evidence shows that children in the Special Friends program may not have had the play skills necessary to engage in extended, independent play interactions during the cooperative learning group activities," Meyer says. "Some of the children weren't sure how to initiate interactions. This may account for the group's decline in the mean number of best friendships."

Other findings showed that self-regulation and social skills are directly related to having at least one best friend and acceptance among peers. "Children who had higher rates of problem behavior and lower social skills also had lower rates of peer acceptance," Meyer says. "However, when children with these social-behavioral characteristics had a best friendship, it did not result in lower peer acceptance scores."

Meyer says that to increase the chances of children with disabilities making friendships, high-quality inclusion models must be structured in a way that creates an environment that supports young children's acceptance, membership and the development of friendships.

"Our research shows that at the same time we're focusing on improving children's social skills and decreasing their challenging behaviors, we also have to be helping them make friends in the classroom because of the protective factors that it has and its effect on producing better social and academic outcomes." she says. "Within our early learning environments we need to think deeply about how we create opportunities for children to grow in both their academic and social skills. This is especially prevalent for children who may enter kindergarten with delays or disabilities that may impact their social-emotional development and impact their ability to develop close friendships with classmates."

Human Calculations and Allah’s Predestination

 

Undoubtedly, true believers are the most patient among all human beings, the most steadfast in hard times, and the most contented in calamities. This can be understood in light of the following:

- Life is short

They realized the shortness of this present life compared with the eternity of the hereafter and, therefore, they did not wish to exchange the paradise of Eden with this perishable, present, short life,

{Say (unto them, O Muhammad): The comfort of this world is scant; the Hereafter will be better for him who wardeth off (evil); and ye will not be wronged the down upon a date stone}. (An-Nisaa’ 4: 77) and, {...The life of this world is but comfort of illusion.} (Aal `Imran 3: 185)

 The Prophets' example
They learned from the biographies and life stories of their Prophets and Messengers that the latter were the most suffering humans in life and at the same time they were the least to enjoy any of this present life’s luxuries or ornaments.

Therefore, the believers did not wish to be better than the Prophets in terms of enjoying any of the luxuries or ornaments of this life. They took the Prophets as their prime model examples in application of Allah’s saying,

{Or think ye that ye will enter Paradise while yet there hath not come unto you the like of (that which came to) those who passed away before you? Affliction and adversity befell them, they were shaken as with earthquake, till the Messenger (of Allah) and those who believed along with him said: When cometh Allah's help? Now surely Allah's help is nigh}. (Al-Baqarah 2: 214)


- Full trust in Allah's Wisdom

They knew that all the trials and ordeals that may befall them are not purposeless strikes of fate; rather, these are exercised in accordance with a perfect plan, predestined scheme, eternal wisdom and divine ordainment.
Therefore, they believed in that whatever befell them was never to miss them and whatever missed them was never to befall them,

{Naught of disaster befalleth in the earth or in yourselves but it is in a Book before We bring it into being – indeed that, for Allah, is easy.} (Al-Hadid 57: 22)


- Allah's Mercy is always there

They learned from the divine attributes of Allah that when He decrees something not seemingly good, He simultaneously coats it with absolute kindness, and when He, Glory is His due, puts someone to the test, He simultaneously relieves him and alleviates his pain,

{...Lo! My Lord is tender unto whom He will. He is the Knower, the Wise.} (Yusuf 12: 100)

And, they learned from the kindness and mercy of Allah that all these misfortunes and distresses are nothing but experiences from which they can derive lessons and examples that can be of great value to their religion and life.


- Difficulties make greatness

They knew that only through these lessons and examples their souls would be purified, faith would be polished, and hearts’ rust would be removed. The Messenger of Allah (peace and blessings be upon him) is reported to have said,

“…No Muslim is afflicted with any harm, even if it were the prick of a thorn, but that Allah expiates his sins because of that, as a tree sheds its leaves.” (Al-Bukhari)

Now, one can say that faith achieves balance in this present life. Where humans may have their own calculations and considerations in all they do and all that is done to them, it is true that Allah may have other schemes that are called ‘fate’ or ‘predestination’ with which He runs and controls all affairs of His creation,

{That which Allah openeth unto mankind of mercy none can withhold it; and that which He withholdeth none can release thereafter. He is the Mighty, the Wise.} (Fatir 35: 2)


Prophet Musa (peace be upon him): A prime example

Let us take an example from the story of Prophet Musa (Moses) (peace be upon him) with Pharaoh and the emancipation of the Children of Israel from slavery. Let us read the following ayahs (i.e. verses) first:

{And when the two hosts saw each other, those with Moses said: Lo! We are indeed caught.

He said: Nay, verily! For lo! My Lord is with me. He will guide me.

Then We inspired Moses, saying: Smite the sea with thy staff. And it parted, and each part was as a mountain vast. Then brought We near the others to that place.

And We saved Moses and those with him, every one; We drowned the others.

Lo! Herein is indeed a portent, yet most of them are not believers.

And lo, thy Lord! He is indeed the Mighty, the Merciful.} (Ash-Shu`araa’ 26: 61-68)

As Prophet Musa (peace be upon him) got out of Egypt accompanied with those who believed in him, he found himself right in front of the Red Sea… a horrible and terrifying situation… the sea was before them while the enemy – Pharaoh and his troops – were behind them and were about to overtake them.
It was indeed a dreadful situation to the extent that some of the believers accompanying Musa were overcome with a feeling of utter despair and said, “We are indeed caught!”

No doubt, the calculations of that group of believers were accurate and precise. The enemy was just behind them while the sea was right before them and there was no way to run or get out of that predicament.

They were too terrified to think of a third possibility. They thought of two possibilities only: either drowning in the sea, or being slain by Pharaoh and his troops. Yes, they couldn’t think of a third possibility that could be standing firm and facing their fierce enemy… that was because they were frightened to death!

I, here, may recall a saying by someone to his friend, “I am frightened of so and so”. His friend replied, “You shouldn’t be as his heart is owned by the One you hope for (i.e., Allah).” Truly, all hearts of creation are in the Hand of Allah Who can change them for the better or overtake them if they insist on sinning, tyranny and injustice and Allah knows that they will never get back to Him in repentance.
Then, the voice of faith was heard; the voice of Prophet Musa (peace be upon him) as he spoke with full reliance on Allah and perfect trust in Him and His promise as saying, “‘Kalla’ (i.e., Nay), verily! For lo! My Lord is with me. He will guide me.”

Linguistically speaking, ‘Kalla’ is a strong negative word in Arabic that means, ‘Nay’ in English. It is much stronger than ‘La’ which is usually translated into English as ‘No’, as the former denotes a sense of confirmation and full trust in what will happen.

Yet, a question may be put forth here: What were the potentials Prophet Musa had at that time to get out of that critical situation?

Indeed, Prophet Musa (peace be upon him) had neither a plan, nor even a proof to support his words, {Nay, verily! For lo! My Lord is with me. He will guide me.} (Ash-Shu`araa’ 26: 62) It was his trust in Allah and his faith that He will fulfill His Divine promise, {…to help believers is incumbent upon Us [Allah]}. (Ar-Rum 30: 47)

Certainly, Allah does not forsake His guided believers and never let them down in times of hardship or calamities. He says in His Ever-Glorious Qur’an,

{If Allah is your helper none can overcome you, and if He withdraw His help from you, who is there who can help you? In Allah let believers put their trust.} (Al `Imran: 160)

And, the Qur’an says in another verse,

{Lo! We verily do help Our messengers, and those who believe, in the life of the world and on the day when the witnesses arise.} (Ghafir 40: 51)

Only then, Allah Almighty stops and changes the laws of nature and the whole universe when unquestioning faith penetrates the hearts of the believers. Thereupon, the Divine Command comes to Musa as,

{…strike for them a dry path in the sea, fearing not to be overtaken, neither being afraid (of the sea).} (Taha 20: 77)

What?!

Strike the sea with the staff?!

Did not he have the staff from the very beginning?!

Did not he see what the staff was capable of doing with the staffs of the sorcerers and their snakes on the day of the feast?!

Yes, indeed, he had the staff. However, his trust was not in the staff; rather, it was in the Lord of the staff Who gives it the Command and it unquestionably obeys and thus makes wonders. Thus, both Musa and the staff can effect no movement or action without the Divine Command of Almighty Allah.

After Prophet Musa (peace be upon him) and those who were with him had crossed the sea, perhaps he intended to use the same staff to get the sea back to its original state to prevent Pharaoh and his troops from crossing it and thus overtaking him and the believers. However, the Divine Command descends on him as,
{And leave the sea behind at rest, for lo! They are a drowned host.} (Ad-Dukhan 44:24)

Prophet Musa got this victory from his faith in Allah. To me, that was intended to be a great sign for all people as it was Allah’s Will to save the believers and destroy the unbelievers using one and the same action, namely, a single strike with the staff. Allah says,

{Then Pharaoh followed with his hosts and there covered them that which did cover them of the sea.} (Taha: 78)

To conclude, where did Prophet Musa (peace be upon him) get this tranquility and trust in Allah’s Victory? It is faith that cannot be shaken or tainted… the absolute faith in the absolute Power of Allah which cannot be limited or defeated by any of the natural laws.

He put to control and run the whole universe in accordance with the criteria He, Glory be His, put forth, and which He can bypass or change whenever and however He wishes:

{He will not be questioned as to that which He doeth, but they will be questioned.} (Al-Anbiya’ 21: 23)

Finally, the most dangerous things that we face in this present life are nothing but weak faith, lack of trust in what is in Allah’s Hand, and complete reliance on the means while being heedless of the Creator of all means and the Sustainer of the whole universe with His perfect Wisdom and absolute Power.


Between faith and worldly means

This does not, in any way, contradict the religious ordinance of adopting all possible means whenever one needs to carry something out. A true Muslim’s belief regarding the adoption of all possible means can be stated as follows: adopting all possible means is obligatory; overlooking them is a sinful deed; and, perfect reliance on them alone is polytheism.
Last but not least, one can summarize all this and say that our state of affairs will not be improved unless the following is attended to:

- To put our complete trust in Allah’s promise, {…Verily Allah helpeth one who helpeth Him. Lo! Allah is Strong, Almighty.} (Al-Hajj 22: 40),

-To find contentedness in all that Allah chooses for us, {Thy Lord bringeth to pass what He willeth and chooseth. They have never any choice. Glorified be Allah and exalted above all that they associate (with Him)! } (Al-Qasas 28: 68), and,

- To insist on invoking Allah and making du`aa’ to Him. Ibn Al-Qayyim once said, “It is about to be opened for him he who incessantly knocks at the door [of Allah].”

Engineering a better future for the Mississippi Delta: Storm surge risks

 

River deltas, low-lying landforms that host critical and diverse ecosystems as well as high concentrations of human population, face an uncertain future. Even as some deltas experience decreased sediment supply from damming, others will see increased sediment discharge from land-use changes. Accurate estimates of the current rate of subsidence in the Mississippi Delta (southern USA) are important for planning wetland restoration and predictions of storm surge flooding.
Parts of coastal Louisiana (southern USA) are undergoing accelerated land loss due to the combined effects of sea-level rise and land subsidence. In the Mississippi Delta, where rates of land loss are especially severe, subsidence of the land surface reflects natural processes, such as sediment compaction and crustal loading, but this is exacerbated by anthropogenic withdrawal of fluids (water, oil, natural gas).
In this study for Geology, Makan Karegar and colleagues use precise Global Positioning System (GPS) data to measure subsidence rates of the Mississippi Delta. They also use tide gauge records to better understand the relationship between subsidence and sea-level rise in southern Louisiana.

The authors show that while the majority of the delta is relatively stable, parts of the delta may not be viable in the long term. The southern portion of the delta continues to experience high rates of subsidence (5 to 6 mm per year). The current rate of relative sea-level rise (the combined effect of land subsidence and sea-level rise) along parts of the coastal delta is nearly 8 to 9 mm per year.

Given stable sea level and sediment deposition, a delta will tend toward an equilibrium state where subsidence is more or less balanced by sediment deposition. In the Mississippi River system, however, a series of dams on various upstream tributaries have reduced sediment supply to the delta, while levees on the lower part of the river have artificially channelized the flow, forcing sediments to be deposited beyond the delta in the deeper Gulf of Mexico.

The data presented by Karegar and colleagues have implications for land reclamation and wetland restoration in the region. Mitigation efforts may include river diversion to encourage resedimentation, and pumping of offshore sands to restore barrier islands.

Finding the body clock's molecular reset button

 

An international team of scientists has discovered what amounts to a molecular reset button for our internal body clock. Their findings reveal a potential target to treat a range of disorders, from sleep disturbances to other behavioral, cognitive, and metabolic abnormalities, commonly associated with jet lag, shift work and exposure to light at night, as well as with neuropsychiatric conditions such as depression and autism.
In a study published online April 27 in Nature Neuroscience, the authors, led by researchers at McGill and Concordia universities in Montreal, report that the body's clock is reset when a phosphate combines with a key protein in the brain. This process, known as phosphorylation, is triggered by light. In effect, light stimulates the synthesis of specific proteins called Period proteins that play a pivotal role in clock resetting, thereby synchronizing the clock's rhythm with daily environmental cycles.
Shedding light on circadian rhythms
"This study is the first to reveal a mechanism that explains how light regulates protein synthesis in the brain, and how this affects the function of the circadian clock," says senior author Nahum Sonenberg, a professor in McGill's Department of Biochemistry.
In order to study the brain clock's mechanism, the researchers mutated the protein known as eIF4E in the brain of a lab mouse so that it could not be phosphorylated. Since all mammals have similar brain clocks, experiments with the mice give an idea of what would happen if the function of this protein were blocked in humans.
Running against the clock
The mice were housed in cages equipped with running wheels. By recording and analyzing the animals' running activity, the scientists were able to study the rhythms of the circadian clock in the mutant mice.
The upshot: the clock of mutant mice responded less efficiently than normal mice to the resetting effect of light. The mutants were unable to synchronize their body clocks to a series of challenging light/dark cycles -- for example, 10.5 hours of light followed by 10.5 hours of dark, instead of the 12-hour cycles to which laboratory mice are usually exposed.
"While we can't predict a timeline for these findings to be translated into clinical use, our study opens a new window to manipulate the functions of the circadian clock," says Ruifeng Cao, a postdoctoral fellow in Dr. Sonenberg's research group and lead author of the study.
For co-author Shimon Amir, professor in Concordia's Department of Psychology, the research could open a path to target the problem at its very source. "Disruption of the circadian rhythm is sometimes unavoidable but it can lead to serious consequences. This research is really about the importance of the circadian rhythm to our general well-being. We've taken an important step towards being able to reset our internal clocks -- and improve the health of thousands as a result."

Babies as young as six months using mobile media

 

More than one-third of babies are tapping on smartphones and tablets even before they learn to walk or talk, and by 1 year of age, one in seven toddlers is using devices for at least an hour a day, according to a study to be presented Saturday, April 25 at the Pediatric Academic Societies (PAS) annual meeting in San Diego.
The American Academy of Pediatrics discourages the use of entertainment media such as televisions, computers, smartphones and tablets by children under age 2. Little is known, however, when youngsters actually start using mobile devices.
Researchers developed a 20-item survey to find out when young children are first exposed to mobile media and how they use devices. The questionnaire was adapted from the "Zero to Eight" Common Sense Media national survey on media use in children.
Parents of children ages 6 months to 4 years old who were at a hospital-based pediatric clinic that serves a low-income, minority community were recruited to fill out the survey. Participants were asked about what types of media devices they have in their household, children's age at initial exposure to mobile media, frequency of use, types of activities and if their pediatrician had discussed media use with them.
Results from 370 parents showed that 74 percent were African-American, 14 percent were Hispanic and 13 percent had less than a high school education. Media devices were ubiquitous, with 97 percent having TVs, 83 percent having tablets, 77 percent having smartphones and 59 percent having Internet access.
Children younger than 1 year of age were exposed to media devices in surprisingly large numbers: 52 percent had watched TV shows, 36 percent had touched or scrolled a screen, 24 percent had called someone, 15 percent used apps and 12 percent played video games.
By 2 years of age, most children were using mobile devices.
Lead author Hilda Kabali, MD, a third-year resident in the Pediatrics Department at Einstein Healthcare Network, said the results surprised her.
"We didn't expect children were using the devices from the age of 6 months," she said. "Some children were on the screen for as long as 30 minutes."
Results also showed 73 percent of parents let their children play with mobile devices while doing household chores, 60 percent while running errands, 65 percent to calm a child and 29 percent to put a child to sleep.
Time spent on devices increased with age, with 26 percent of 2-year-olds and 38 percent of 4-year-olds using devices for at least an hour a day.
Finally, only 30 percent of parents said their child's pediatrician had discussed media use with them.

We think better on our feet, literally

 

A study from the Texas A&M Health Science Center School of Public Health finds students with standing desks are more attentive than their seated counterparts. In fact, preliminary results show 12 percent greater on-task engagement in classrooms with standing desks, which equates to an extra seven minutes per hour of engaged instruction time.
The findings, published in the International Journal of Health Promotion and Education, were based on a study of almost 300 children in second through fourth grade who were observed over the course of a school year. Engagement was measured by on-task behaviors such as answering a question, raising a hand or participating in active discussion and off-task behaviors like talking out of turn.
Standing desks -- also known as stand-biased desks -- are raised desks that have stools nearby, enabling students to sit or stand during class at their discretion. Mark Benden, Ph.D., CPE, associate professor at the Texas A&M Health Science Center School of Public Health, who is an ergonomic engineer by trade, originally became interested in the desks as a means to reduce childhood obesity and relieve stress on spinal structures that may occur with traditional desks. Lessons learned from his research in this area led to creation of Stand2Learn™, an offshoot company of a faculty-led startup that manufactures a classroom version of the stand-biased desk.
Benden's previous studies have shown the desks can help reduce obesity -- with students at standing desks burning 15 percent more calories than students at traditional desks (25 percent for obese children) -- and there was anecdotal evidence that the desks also increased engagement. The latest study was the first designed specifically to look at the impact of classroom engagement.
Benden said he was not surprised at the results of the study, given that previous research has shown that physical activity, even at low levels, may have beneficial effects on cognitive ability.
"Standing workstations reduce disruptive behavior problems and increase students' attention or academic behavioral engagement by providing students with a different method for completing academic tasks (like standing) that breaks up the monotony of seated work," Benden said.
"Considerable research indicates that academic behavioral engagement is the most important contributor to student achievement. Simply put, we think better on our feet than in our seat."
The key takeaway from this research, Benden said, is that school districts that put standing desks in classrooms may be able to address two problems at the same time: academic performance and childhood obesity.
Additional Texas A&M researchers involved with the study, which was funded by the National Institutes of Health, were Hongwei Zhao, Ph.D., professor of epidemiology and biostatistics at the Texas A&M School of Public Health; Jamilia Blake, Ph.D., assistant professor of educational psychology at the Texas A&M College of Education; and Marianela Dornhecker, doctoral student in educational psychology at the Texas A&M College of Education. Monica Wendel, Dr.P.H., associate dean for public health practice at the University of Louisville, also contributed to the research.

7 Apple Watch Apps You Need to Try

PHOTO: ABC News technology editor Alyssa Newcomb tries on an Apple Watch Sport.

Screen real estate is at a premium on the Apple Watch and has challenged developers to figure out how to create unique and valuable experiences for the wrist.
Along with the arrival of the Apple Watch today, more than 3,000 apps have been optimized for the wearable device -- including many social networking staples, such as Facebook, Instagram and Twitter.
"Developers need to give a lot of thought how they translate their iPhone app experience to the watch," Patrick Moorhead, an analyst at Moor Insights & Strategy, told ABC News. "Developers need to get the right information at the right time on their watch apps. It needs to have great load times, too, or users will just get frustrated and use another app." 
While there are plenty of apps worth trying, here are seven of the early standouts that will help you get from morning to night.

WebMD

We all know WebMd as a repository of medical knowledge and the place we go to when (insert body part here) hurts. The medical website's Apple Watch experience focuses on making it even easier to follow the doctor's orders.
A medication reminder will help keep wearers on track, letting them know when they need to take their medication and the proper dosage.

Citymapper

Never get lost again. Citymapper helps navigate public transit by giving you the fastest route. You won't miss your stop either -- the app will give the wearer a gentle tap when they've reached their destination.

Mint

The Mint app makes it easy to keep an eye on your spending via your watch. Alerts will help users make sure they're sticking to their budget.

MLB at Bat

Baseball fans never have to miss a moment from their favorite teams. The MLB app lets wearers follow a game as its happening, along with in-game scoring, pitch counts, base positions and player stats.

PowerPoint

Here's one way to take your PowerPoint presentation to the next level -- use your Apple Watch. The PowerPoint for the Apple Watch app acts as a remote control, allowing the wearer to control the speed of their presentation.

Chipotle

It's easier than ever to get your burrito fix. Using the Chipotle app, hungry customers can find the nearest restaurant, choose their order, pay for it and pick it up when it's ready. A countdown clock in the app lets users know when it's burrito time.

OpenTable

Never forget a reservation again. The OpenTable app offers glanceable moments to remind users of upcoming dining plans, along with directions for how to get to the restaurant. It will also offer an alert if it's a "Pay with OpenTable" restaurant, which will allow wearers to use Apple Pay in the app -- and stealthily pick up the check for their dinner date.

World Happiness Report 2015 ranks happiest countries

 

Since it was first published in 2012, the World Happiness Report demonstrated that well-being and happiness are critical indicators of a nation's economic and social development, and should be a key aim of policy. This year's report looks at the changes in happiness levels in 158 countries, and examines the reasons behind the statistics. The World Happiness Report 2015 also comes in advance of three high-level negotiations that will give world leaders the opportunity to reshape the global agenda and move the world towards a sustainable development agenda that includes well-being as an essential element.
"The aspiration of society is the flourishing of its members," said Jeffrey Sachs, Director of the Earth Institute, Columbia University. "This report gives evidence on how to achieve societal well-being. It's not by money alone, but also by fairness, honesty, trust, and good health. The evidence here will be useful to all countries as they pursue the new Sustainable Development Goals."
The report, produced by the Sustainable Development Solutions Network (SDSN), contains analysis from leading experts in the fields of economics, neuroscience, national statistics, and describes how measurements of subjective well-being can be used effectively to assess national progress. The report is edited by Professor John F. Helliwell, of the University of British Columbia and the Canadian Institute for Advanced Research; Professor Richard Layard, Director of the Well-Being Programme at LSE's Centre for Economic Performance; and Professor Sachs, Director of the Earth Institute and SDSN.
The first World Happiness Report, released in 2012 ahead of the UN high-level meeting on Happiness and Well-being, drew international attention as a landmark first survey of the state of global happiness. This latest report digs even deeper into the data looking at country trends since the first report, regional indicators, factors in gender and age, and the importance of investing in social capital.
The report identifies the countries with the highest levels of happiness:
  1. Switzerland
  2. Iceland
  3. Denmark
  4. Norway
  5. Canada
"As the science of happiness advances, we are getting to the heart of what factors define quality of life for citizens," said Helliwell. "We are encouraged that more and more governments around the world are listening and responding with policies that put well-being first. Countries with strong social and institutional capital not only support greater well-being, but are more resilient to social and economic crises."
As previous reports have done, The World Happiness Report 2015 reveals trends in the data judging just how happy countries really are. On a scale running from 0 to 10, people in over 150 countries, surveyed by Gallup over the period 2012-15, reveal an average score of 5.1 (out of 10). Six key variables explain three-quarters of the variation in annual national average scores over time and among countries: real GDP per capita, healthy life expectancy, having someone to count on, perceived freedom to make life choices, freedom from corruption, and generosity. This year for the first time ever, the Report breaks down the data by gender, age, and region. It finds striking differences, some much larger than have previously been found.
"A positive outlook during the early stages of life is inherently desirable, but it also lays the foundation for greater happiness during adulthood," said Layard. "As we consider the value of happiness in today's report, we must invest early on in the lives of our children so that they grow to become independent, productive and happy adults, contributing both socially and economically."
The World Happiness Report 2015 shows that at both the individual and national levels, all measures of well-being, including emotions and life evaluations, are strongly influenced by the quality of the surrounding social norms and institutions. These include family and friendships at the individual level, the presence of trust and empathy at the neighborhood and community levels, and power and quality of the over-arching social norms that determine the quality of life within and among nations and generations. When these social factors are well-rooted and readily available, communities and nations are more resilient.
The report also demonstrates that a key national challenge is to ensure that policies are designed and delivered in ways that enrich the social fabric, and teach the power of empathy to current and future generations. Under the pressures of putting right what is obviously wrong, there is often too little attention paid to building the vital social fabric. According to the report, paying greater attention to the levels and sources of subjective well-being has helped us to reach these conclusions, and to recommend making and keeping happiness as a central focus for research, policy and practice.

Hunt for ancient royal tomb in Mexico takes mercurial twist



A Mexican archeologist hunting for a royal tomb in a deep, dark tunnel beneath a towering pre-Aztec pyramid has made a discovery that may have brought him a step closer: liquid mercury.
In the bowels of Teotihuacan, a mysterious ancient city that was once the largest in the Americas, Sergio Gomez this month found "large quantities" of the silvery metal in a chamber at the end of a sacred tunnel sealed for nearly 1,800 years.
"It's something that completely surprised us," Gomez said at the entrance to the tunnel below Teotihuacan's Pyramid of the Plumed Serpent, about 30 miles (50 km) northeast of Mexico City.
Some archeologists believe the toxic element could herald what would be the first ruler's tomb ever found in Teotihuacan, a contemporary of several ancient Maya cities, but so shrouded in mystery that its inhabitants still have no name.
Unsure why the mercury was put there, Gomez says the metal may have been used to symbolize an underworld river or lake. Previously uncovered in small amounts at a few Maya sites much further south, it had never been found in Teotihuacan.
Difficult to mine and prized for its reflective properties, mercury was rare in ancient Mexico. Archaeologists believe may have lent it a supernatural significance for ritual ends.
ROYAL TOMB SOUGHT
Deeper into the complex comprising three chambers, Gomez expects to find the elusive last resting place of a king.
If Gomez is right, it could help settle a debate over how power was wielded in Teotihuacan, a city boasting massive stone pyramids that was home to as many as 200,000 people and the heart of ancient empire that flourished between 100 and 700 A.D.
Teotihuacan, or "abode of the gods" in the Aztec language of Nahuatl, was distinct from the Mayan civilization. Its inhabitants left behind no written record, abandoning the city long before the Aztecs came to power in the 14th century.
Spaniards dug at Teotihuacan in the 1670s, but rigorous scientific excavation of the site did not begin until the 1950s.
Gomez's six-year slog in the tunnel has already yielded tens of thousands of artifacts including stone sculptures, fine jewelry and giant seashells leading to the three chambers. The painstaking excavation has slowed due to extreme humidity, mud, and now, the need for protective gear to avoid mercury poisoning.
George Cowgill, a U.S. archeologist who has spent more than four decades excavating Teotihuacan, says the mercury find increases the odds of finding a tomb.
"But it's still very uncertain, and that is what keeps everybody in suspense," he added.
Mexican archeologist Linda Manzanilla believes that at its peak, the city was ruled not by a single king, but a council of four lords, and that Gomez may find the remains of one of them.
To bolster her argument, she cites the absence of a single palace or the presence of kings in any of the city's many murals.
The excavation of the chambers should be finished by October, Gomez said, with an announcement of findings by the end of 2015 .

Scientists create the sensation of invisibility

 

The power of invisibility has long fascinated man and inspired the works of many great authors and philosophers. In a study from Sweden's Karolinska Institutet, a team of neuroscientists now reports a perceptual illusion of having an invisible body, and show that the feeling of invisibility changes our physical stress response in challenging social situations.
The history of literature features many well-known narrations of invisibility and its effect on the human mind, such as the myth of Gyges' ring in Plato's dialogue The Republic and the science fiction novel The Invisible Man by H.G. Wells. Recent advances in materials science have shown that invisibility cloaking of large-scale objects, such as a human body, might be possible in the not-so-distant future; however, it remains unknown how invisibility would affect our brain and body perception.
In an article in the journal Scientific Reports, the researchers describe a perceptual illusion of having an invisible body. The experiment involves the participant standing up and wearing a set of head-mounted displays. The participant is then asked to look down at her body, but instead of her real body she sees empty space. To evoke the feeling of having an invisible body, the scientist touches the participant's body in various locations with a large paintbrush while, with another paintbrush held in the other hand, exactly imitating the movements in mid-air in full view of the participant.
"Within less than a minute, the majority of the participants started to transfer the sensation of touch to the portion of empty space where they saw the paintbrush move and experienced an invisible body in that position," says Arvid Guterstam, lead author of the present study. "We showed in a previous study that the same illusion can be created for a single hand. The present study demonstrates that the 'invisible hand illusion' can, surprisingly, be extended to an entire invisible body."
The study examined the illusion experience in 125 participants. To demonstrate that the illusion actually worked, the researchers would make a stabbing motion with a knife toward the empty space that represented the belly of the invisible body. The participants' sweat response to seeing the knife was elevated while experiencing the illusion but absent when the illusion was broken, which suggests that the brain interprets the threat in empty space as a threat directed toward one's own body.
In another part of the study, the researchers examined whether the feeling of invisibility affects social anxiety by placing the participants in front of an audience of strangers.
"We found that their heart rate and self-reported stress level during the 'performance' was lower when they immediately prior had experienced the invisible body illusion compared to when they experienced having a physical body," says Arvid Guterstam. "These results are interesting because they show that the perceived physical quality of the body can change the way our brain processes social cues."
The researches hope that the results of the study will be of value to future clinical research, for example in the development of new therapies for social anxiety disorder.
"Follow-up studies should also investigate whether the feeling of invisibility affects moral decision-making, to ensure that future invisibility cloaking does not make us lose our sense of right and wrong, which Plato asserted over two millennia ago," says principal investigator Dr. Henrik Ehrsson, professor at the Department of Neuroscience.
This research was funded by the Swedish Research Council, and the Söderberg Foundation.

Google launches Project Fi, US wireless service designed to curb data use



New service switches between Wi-Fi and cellular networks to keep phone bills low, and will only work on Google’s Nexus 6 phones through Sprint and T-Mobile
Google on Wednesday launched a new US wireless service that switches between Wi-Fi and cellular networks to curb data use and keep phone bills low.
The service, Google’s first entry into the wireless industry, will work only on the company’s Nexus 6 phones and be hosted through Sprint Corp and T-Mobile’s networks, Google said in a statement.
Called Project Fi, the service will automatically switch between the two networks and more than 1m open, free Wi-Fi spots, depending on which signal is strongest.
The service will cost $20 a month plus $10 per gigabyte of data used. Customers will get money back for unused data.
Sundar Pichai, Google’s senior vice-president of products, said at a Barcelona conference last month the company was preparing to experiment with a mobile network, but that it did not intend to disrupt the wireless industry.
The service will be available on only one device and has limited carrier coverage, so it will not make Google a major wireless industry player, said Brian Blau, research director at Gartner.
If successful, however, Google’s service could pressure wireless providers to further lower prices and better adapt to the rise of tablets and wearable devices, Blau added. Though some carriers, such as T-Mobile and AT&T Inc, allow unused data to roll over, most mobile plans require customers to pay for a set amount of data each month.
But Google first has to “test out features they think are going to differentiate themselves,” Blau said, such as being able to transition from network connectivity to Wi-Fi.
If Google is able to provide those features, “it’s very possible they could become a major wireless player in the future,” Blau said.
Phone numbers will live in the cloud so that consumers can talk and text on any connected tablet, Google said.
The company already has a strong presence in the mobile market through its Android operating system, which hosts some of the most popular apps, such as Gmail and Google Maps.

Chinese paper on embryo engineering splits scientific community

Chinese paper on embryo engineering splits scientific community

The announcement that a Chinese team had altered the genetics of a human embryo for the first time has ignited a firestorm of controversy around the world and renewed recent calls for a moratorium on any attempt to establish a pregnancy with such an engineered embryo. But it has also underscored that although scientists are united in their opposition to any clinical application of such embryo manipulation, they are split on the value of basic research that involves genetically modifying human embryos.
In China itself, where the precedent-setting research is big news and some in the public have expressed concern on the Internet about the embryo experiments, "most scientists are more positive," says Guo-Qiang Chen, a microbiologist at Tsinghua University in Beijing. "My personal opinion is that as long as they can control the consequences they should continue this work.”
That viewed is echoed by many outside of China as well. “I personally would defend the fundamental scientific value of research into gene editing” in human embryos, in part to explore the risks of any potential clinical use, George Daley, a stem cell biologist at Harvard Medical School in Boston, tells Science.
The paper at the heart of the debate, published online on 18 April in Protein & Cell, an obscure Chinese online journal published by an affiliate of China’s Ministry of Education, drew widespread attention only after Nature News reported it online on 22 April. Junjiu Huang and colleagues at Sun Yat-sen University in Guangzhou described how they attempted to use the CRISPR/Cas-9 system, a new technology that makes it easy to modify genes in cells, to edit the hemoglobin-B gene (HBB) in 86 human embryos donated for research by couples at an in vitro fertilization (IVF) clinic. In theory, this could be a way to prevent beta thalassemia, a blood disorder that results when that gene is mutated, but the embryos experimented on were selected because they were not viable; they had an extra set of chromosomes as a result of being fertilized by two sperm.
Two days after being injected with gene-editing molecules, only four of 54 surviving embryos that were tested carried the desired genetic changes; these embryos were mosaic, meaning only some cells had the intended changes. The edited embryos also had a large number of off-target effects, or mutations in genes other than HBB, that could be potentially harmful.
The performance of the technique proved so poor that the researchers emphasized that any clinical use of CRISPR/Cas9 for embryo editing is “premature at this stage." The project was reviewed by Huang’s university’s ethics board and complied with international and national ethical standards, according to the paper. The researchers used abnormal zygotes that would otherwise be discarded, “because ethical concerns preclude studies of gene editing in normal embryos,” they write.
Still, the paper drew anger from some quarters. The Center for Genetics and Society in Berkeley, California, called for a halt to such experiments. Huang told Nature News that the paper was rejected by Science and Nature in part because of ethical concerns. (In an e-mail, Huang initially welcomed an inquiry from Science and asked for a list of questions by e-mail, but then he did not reply.)
Rumors that such a paper was in the works sparked several published opinion pieces a month ago. In a commentary in Science, molecular biologist David Baltimore, president emeritus of California Institute of Technology in Pasadena, and 17 co-authors called for scientists and others to “strongly discourage … attempts at germline genome modification for clinical application in humans.”  (Many countries already ban germline gene modification.)
Several scientists led by Edward Lanphier, CEO of Sangamo BioSciences in Richmond, California, went further in a Nature commentary, calling for a voluntary moratorium on all experiments involving germline gene modification. Although the two groups were “90% in agreement,” they differed on this one point, Lanphier told Science: “We said let’s not perfect these technologies ahead of a conversation whether we should allow this technology.”
In contrast, two co-authors of the Science commentary say that they are comfortable with the Huang experiment. Daley points out that international guidelines developed by the stem cell researchers allow for experiments with human embryos as long as the cells are not allowed to grow for more than 14 days. “To further to inform any debate on whether this technology could be useful for eradicating disease, one has to understand the range of efficacy and off-target mutagenesis,” Daley says.
Harvard molecular geneticist George Church agrees that the consensus has long been that experiments on discarded IVF embryos are acceptable; the only new thing is that the Huang group “used CRISPR, which makes it noteworthy,” he says. Although he does not object to the the reported experiment, Church adds that the results “were fairly predictable.” He says one reason the researchers got so many off-target effects is because they did not use the latest version of the gene-editing technology.
But University of California, Berkeley, molecular biologist Jennifer Doudna, who organized a workshop that led to the Science commentary, says her personal opinion is that the Huang experiment was not necessary because scientists are still a long way from perfecting the CRISPR gene-editing method. “I don't see the value in working with human embryos right now. There’s a lot to be learned by working in other systems,” she says. In her view, the Huang paper provided little new scientific insight and seemed intended to “attract attention.” She is also troubled that, according to the dates noted in the paper, Protein & Cell apparently published the study 1 day after it was submitted. “I have to conclude this was not peer reviewed,” she says.
Neither Science nor Nature’s editorial staff would confirm that the journals reviewed the paper and rejected it in part because of of ethical concerns. In a statement, a Nature representative said the journal sometimes has papers reviewed by a bioethicist. Science issued a statement saying it supports recommendations in its earlier commentary and that while a consensus about germline genome editing is being developed, the journal “will carefully scrutinize all submissions for both technical and societal concerns and consult broadly.”
Chen, who uses CRISPR/Cas9 in his own research on microorganisms, and other scientists in China defend their country's ethical oversight of the new embryo research. Ethical review procedures in the United States and in China are very similar and based on the same principles, says Kehkooi Kee, a stem cell scientist also at Tsinghua, who earned his advanced degrees in the United States. Kee says that at Tsinghua a proposal for such work would have to be vetted by the university hospital's own institutional review board (IRB) as well as by the IRB of the collaborating hospital that supplies the donated embryos. At the national level, he says China's funding agencies do check on whether a grant applicant has the proper ethical approvals. Chen adds that in light of the current controversy, review boards "will probably be more strict," he says.
But he’s adamant the newly published research has value even if some consider its results a failure. Determining if these embryo engineering techniques can be useful in curing disease can be achieved "only by doing this kind of research; we might possibly see some positive outcome resulting from many failures," he says. Kee also defends the work. "The conclusion is valid, they are not hiding anything, and they are not saying this technique is ready for use in the clinic," he says.
The China work was funded by national grants and rumors continue to circulate that several other China teams have done similar embryo work. In the United States, such experiments could only take place with nonfederal funding because of a long-standing congressional prohibition on using federal funding for any research that destroys or puts at risk human embryos.
Regardless of where scientists stand on this new research, it has highlighted their shared desire to discuss whether, if ever, gene editing should be used in human embryos to prevent disease. Doudna is now helping to organize an international meeting later this year to come up with guidelines. “I think the goal of that meeting is to come together and identify a broader consensus about the appropriate way to proceed with these experiments,” she says. Now that the first human embryo gene-editing paper has been published, she adds, “we feel some urgency.”

Oil and gas operations could trigger large earthquakes

Earthquake hazard in central Oklahoma (left) due to oil and gas operations is now comparable to the natural hazard in southeastern Missouri (right). 

The U.S. Geological Survey (USGS) has taken its first stab at quantifying the hazard from earthquakes associated with oil and gas development. The assessment, released in a preliminary report today, identifies 17 areas in eight states with elevated seismic hazard. And geologists now say that such induced earthquakes could potentially be large, up to magnitude 7, which is big enough to cause buildings to collapse and widespread damage.
The new bull’s-eyes on the map, regions such as central Oklahoma, have short-term hazards that are comparable to the those in traditional earthquake states, like California, says Mark Petersen, chief of the USGS National Seismic Hazard Mapping Project in Golden, Colorado. “These earthquakes are occurring at a higher rate than ever before and pose a much greater threat to people living nearby,” he says. “This report represents our first step in identifying and quantifying the ground shaking from induced earthquakes.”
Geoscientists have known for decades that the injection of fluid can increase pressures within the pores of deep rock formations, pushing faults that are already critically stressed by forces in Earth’s crust past the snapping point. But the phenomenon has been brought to the fore by an extraordinary rise in small earthquakes across parts of the central United States. That surge has coincided in time and place with the boom in unconventional oil and gas extraction such as hydraulic fracturing, or "fracking," in which high-pressure fluid is injected into the ground to break up the underlying rock and release trapped gas or oil. In most cases, the earthquakes are not due to fracking itself, which is usually completed in hours or days. Rather, the culprit is typically wastewater disposal, where high volumes of water extracted in oil and gas operations is reinjected into deep basement rocks, where the bigger and more dangerous faults lie.
So far, the largest induced earthquake in the United States has been the 2011 magnitude-5.6 earthquake in Prague, Oklahoma, which damaged dozens of buildings. But geoscientists now say there is no reason why oil and gas operations couldn’t end up triggering something much larger. “There are certainly faults large enough to produce a magnitude 7,” says Justin Rubinstein, a geophysicist at USGS in Menlo Park, California, and a co-author of the new report. “We can’t rule this out.”
In July 2014, USGS published its most recent update to its national seismic hazard map, which is incorporated into engineering codes for buildings and bridges. The hazard is expressed in terms of the probability of exceeding a certain level of shaking in 50 years—not only because the hazard in places like California is not expected to change much over that time period, but also because 50 years—the typical life span of a building—is a useful period of time for engineers.
But that map ignored the threat of induced earthquakes, precisely because the frequency of these earthquakes was likely to change over the course of 50 years. Economic or policy conditions could affect the frequency of induced earthquakes, Petersen says. In short order, wastewater wells could be drilled in new locations, the falling price of oil could shut down certain operations, or regulators could change their policies in certain regions. To account for that uncertainty, the new map describes probabilities over an extremely short, 1-year interval.
The report is a preliminary study that is going to be revised later this year, Petersen says. But William Ellsworth, a geophysicist at USGS in Menlo Park, suggests that it could still be useful—for instance, for state transportation departments trying to prioritize which bridges should be singled out for repairs or retrofits first.
Science agencies and regulators finally seem to be taking induced earthquakes seriously. For a long time, the Oklahoma Geological Survey was reluctant to link the earthquakes to oil and gas operations. But in a statement released on 21 April, the agency now says that it is “very unlikely” that the surge in earthquakes represents a natural process. At a teleconference the following day, held in conjunction with unveiling the new USGS report, Austin Holland, the state seismologist at the Oklahoma Geological Survey in Norman, went even further, saying, “The vast majority of these [earthquakes], we suspect, are from waste water disposal.”

Huge Magma Chamber Spied Under Yellowstone Supervolcano


Yellowstone Volcano 

Scientists have spied a vast reservoir of hot, partly molten rock beneath the supervolcano at Yellowstone National Park that's big enough to fill the Grand Canyon 11 times over.

The newly discovered magma chamber — located 12 to 28 miles underground — is four times bigger than the previously known chamber above it, according to imaging by researchers at the University of Utah.

The discovery fills a missing link in Yellowstone's volcanic plumbing system. But scientists said it doesn't increase the risk of an eruption, which is estimated to happen every 700,000 years.

Researchers now think hot and semi-molten rock is carried upward from 40 miles beneath the surface to the newly found reservoir and the chamber above it.

Yellowstone, which spans parts of Wyoming, Montana and Idaho, is among the world's largest supervolcanoes, with frequent earthquakes. The park attracts millions of tourists with its geysers, hot springs and bubbling mud pots. The upper magma chamber powers Yellowstone's geysers and was responsible for three ancient volcanic eruptions that coated much of North America in ash.

Scientists mapped the new reservoir by doing the geological equivalent of a CT scan — studying how seismic waves pass through different types of rocks.

Their findings were published in Friday's edition of the journal Science.

Can Creativity Exist with Mental Disorders?

Human Brain 

With every hour passing, medicine and human sciences make fascinating steps that build up to extend the bridge between us and the secrets of the absolute wonder created by God which is our human brain.
Today, research in the field of mental illnesses is nonstop. People who suffer from mental sicknesses including Obsessive Compulsive Disorder, Schizophrenia, Autism, Bipolar Disorder and many others have been subject to neurologists’ and psychologists’ zealous studies.
Let’s take a moment to ask ourselves, are people who suffer from such diseases really underprivileged? Is it a completely dark state with no way out or a glimmer of hope? The answer is a definite negative.
Why, you ask? It’s because as much as these illnesses hold of pain and turmoil for the patients; it also holds a great, unmistakable deal of positive traits that can lead the patient to discover the genius within him/her.
In every culture, there exists a widespread stereotype known as “The Tortured Artist”. This kind of intellect, according to the stereotype, often feels alienated and misunderstood by the society which doesn’t appreciate him/her or what he/she does. The tortured artist is always ridden by inner conflicts and feelings of frustration and insufficiency.
However; the notion of a link between "madness" and "genius" goes way back as ancient as the time of Aristotle. During the Romantic era in Europe, toward the end of the 18th century, this idea of art and psychotic patients was reinforced. Individuals with mental issues were believed to have the capacity to see the world in a new, unusual and original way, in other words, to see things that normal humans cannot.
Geniuses with Neurological Disorders

Examples of intellects responsible for historic creative achievements, famous or not, are all around us. Ludwig van Beethoven, the famous German musician suffered from bipolar disorder, yet he possessed such creative power that allowed him to compose pieces that changed classical music forever. He was a child prodigy, although he had “manic” episodes that seemed to fuel his creativity.
During times of psychological torment and extreme suffering, he wrote fantastic pieces. It took him 12 years to finish his last 9th Symphony while he suffered from deafness!
Another example is John Forbes Nash, American Nobel Prize Winner in mathematics, who suffered from Schizophrenia. His life story and life-long battle was documented in the book "A Beautiful Mind," by Sylvia Nasar, which was later made into a movie of the same name.
British Autistic architectural artist, Stephen Wiltshire, was able to draw the Manhattan skyline only from his photographic memory after a helicopter flight over the city. He was diagnosed with autism at the age of three, and has an unusually powerful photographic memory that he has applied to rendering cityscapes, like London, Tokyo, Hong Kong, Rome, Madrid, Frankfurt, Dubai, and Jerusalem.
There are many other examples, like Isaac Newton, the English physicist who is considered to be one of the most influential scientists, suffered from Bipolar Disorder, Vincent Van Gogh, the famous Dutch painter had clinical depression, and Sylvia Plath, the great American writer, who also suffered from clinical depression and suicidal tendencies. And the list goes on.
Such numerous illustrations of the undeniable link between genius and madness lead us to think that there must be a biological connection between these tormented yet brilliant minds.
A study by Arnold Ludwig, a professor of Psychiatry at the University of Kentucky, explored how mental illness is linked with an individual’s influence on society.
Ludwig examined the lives of 1,004 well-known individuals through history, which confirmed that there was a noticeably higher existence of mental illness in individuals who were poets, fiction writers, visual artists, musicians and composers, and those involved in theatre, than in other professions, such as business, exploration, or the military. Many studies like this were conducted, however; they lacked evidence as to how creativity and mental illness are connected.
It is important to point out that while a connection exists between these two traits, it is not always present. Creativity can exist without mental illness, and vice versa.
Biological Story Behind it
frontal-lobe 
To be able to legitimately prove their findings, researchers started to identify the neurological similarities between mental illnesses and the creative thought process.
The frontal lobe of the brain, which is the main connection between the temporal and parietal lobes, is where knowledge and concepts are kept. Unnatural occurrences in the frontal lobe, the prefrontal cortex in particular, are characteristics of schizophrenia and depression.
Hyperactivity in this part causes the patient to initiate unusual connections between normally unrelated things or ideas, in turn simulating the delusions of the paranoid schizophrenic or maniac behavior. Schizophrenia is linked to high levels of dopamine in the prefrontal cortex, causing delusions, hallucinations, and chaotic thought processes.
Similarly, manic depression may involve varying levels of norepinephrine in the frontal lobe; high levels of which are responsible for depression symptoms, while low levels result in novel connectivity in the frontal lobe, and creative or unusual ideas.
According to numerous medical studies, creative thinking, like manic depression and schizophrenia, also involves unusual frontal lobe behavior. Frontal lobe deficiency may decrease idea production.
Similarly, another study supports the ones mentioned above and further proves that unusual activity in the frontal lobe could be responsible for interference of the information stored in the parietal and temporal lobes in innovative ways.
Mentally-disordered Minds Benefit their Societies
Even though, it’s philosophically and medically proven that a lot of individuals with psychological problems can develop or already have astonishing talents, the culture of trying to help those patients by uncovering their talents is scarcely spread in our world, and they’re automatically believed to be destined to be underprivileged – without a positive output of their illness.
There are many ways through which we can help lessen the amount of suffering these patients go through and help them find a bright side to their illness. Doctors need to focus more on developing the hidden talents inside those patients' brains instead of just relying on pills and medication that might hinder the creative thought process that could hold potential of lots of special things those patients can do.
The research in the field of neuropsychology never stops, in hopes that in the soon future, we will be 
able to give and receive more from the mentally-ill.

Breath test 'could give clues to stomach cancer risk'

 


A simple breath test could help predict whether people with gut problems are at high risk of developing stomach cancer, an early study shows.

It detects tiny chemical compounds in people's breath, in an attempt to distinguish unique "breath prints" in those with risky pre-cancerous changes.

Experts say if proven in large trials, it could spot patients on the brink of cancer so they can be treated earlier.

But more work is needed to validate the test, which appears in the journal Gut.
'Sniffing signals'

Stomach cancers affect about 7,300 people each year in the UK.

But in most Western countries it is diagnosed late when the chance of survival is poor. This is partly because symptoms - such as indigestion and pain - can be mistaken for other diseases.

Scientists believe earlier detection may help improve the prognosis.

The new "nanoarray" breath test builds on earlier work from researchers in Israel, Latvia and China.

It relies on the idea that people with cancer may have unique breath signatures - containing minute chemical compounds that are not found in the breath of people free from the illness.

Researchers studied breath samples from 145 patients. Around 30 of these were already known to have stomach cancer.

The rest had been referred for investigations because of concerning symptoms. They did not have full-blown cancer - but some had worrying changes that doctors call "pre-cancerous" that could develop into malignancies.

Scientists tried out the test on a number of different scenarios.

It was fairly good at spotting cancerous samples from non-cancerous ones.

And it showed some promise at identifying worrying pre-cancerous changes that were at high risk of developing into the disease.

But it was not accurate in every case - some patients were misdiagnosed as being at high risk.

Scientists say more work is needed before it is ready to use in clinics.

Dr Emma Smith of Cancer Research UK, said: "Diagnosing cancer in its early stages offers patients the best chance of successful treatment, so research like this has potential to help save lives.

"But we would need to be sure the test is sensitive and accurate enough to be used more widely."

Research involving thousands of European patients is now under way.

India's IT plans suffer from power cuts, congestion - and monkeys


 
As India launches an $18 billion plan to spread the information revolution to its provinces, the problems it faces are a holdover from the past - electricity shortages, badly planned, jam-packed cities, and monkeys.

The clash between the old world and the new is sharply in focus in the crowded 3,000-year-old holy city of Varanasi, where many devout Hindus come to die in the belief that doing so will give them salvation. Varanasi is also home to hundreds of macaque monkeys that live in its temples and are fed and venerated by devotees.

But the monkeys also feast on the fiber-optic cables that are strung along the banks of the Ganges river.

"We cannot move the temples from here. We cannot modify anything here, everything is built up. The monkeys, they destroy all the wires and eat all the wires," said communications engineer A.P. Srivastava.

Srivastava, who oversees the expansion of new connections in the local district, said his team had to replace the riverside cables when the monkeys chewed them up less than two months after they were installed.

He said his team is now looking for alternatives, but there are few to be found. The city of over 2 million people is impossibly crowded and laying underground cable is out of the question. Chasing away or trapping the monkeys will outrage residents and temple-goers.

Varanasi is part of the parliamentary constituency of Prime Minister Narendra Modi, a Hindu nationalist leader who came to power last May.

A shortage of electricity is further complicating efforts to set up stable Wi-Fi in public places - daily power cuts can last for hours during the sweltering summer in Varanasi and across much of India.

Modi's government has pledged to lay 700,000 kms (434,960 miles) of broadband cable to connect India's 250,000 village clusters within three years, build 100 new "Smart Cities" by 2020 and shift more public services like education and health to electronic platforms to improve access and accountability.

Varanasi was the first of an eventual 2,500 locations singled out for street-level Wi-Fi.

Industry experts predict that the broadband initiative, along with a surge in smartphone ownership, will mean about a third of Indians will have access to the internet by 2017, from about 20 percent, or 250 million people, now.

Expanding internet connectivity and making access cheaper could add up to 1.6 percentage points, or about $70 billion, to India's GDP over a four-year period, consultants at McKinsey have estimated.

GLOBAL INTEREST

Global technology companies see opportunity in Modi's commitment to a digital future and are adapting their products to India's varied climates and external threats.

IBM is in discussions to provide software to help several cities make the leap into the digital age.

Network provider Cisco Systems is working with the government in the eastern city of Visakhapatnam to bring more education and healthcare services online, and has developed a "ruggedised" Wi-Fi box to survive India's varied climates and cut down on the need for cables that will be at the mercy of the elements - or monkeys.

"We've built outdoor Wi-Fi-access routers specifically keeping in mind Indian environmental conditions," Dinesh Malkani, Cisco's India country head, said in an interview.

"You cannot predict what challenges you are going to come up against."

Bringing some order to India's chaotic cities with technology is a daunting task.

India's urban population is forecast to swell by an additional 220 million to 600 million by 2031, potentially overwhelming already inadequate infrastructure.

Many of the new digital projects are simply aimed at improving existing civic amenities: time traffic information to help people better plan their journey, or systems that allow individuals to monitor water leakages or waste management and then inform local authorities.

Vinod Kumar Tripathi, an urban planning expert in Varanasi, said Modi's initiatives needed to be coupled with huge investments in improving basic services like housing, roads and waste management.

"Everything here is old, outdated and the population pressure just makes it worse. This place was a small temple town and is now a commercial center," Tripathi said in his office overlooking the Banaras Hindu University.

The free Wi-Fi service that started in February is certainly stimulating the consumer economy. Boatman Sandeep Majhi makes a living ferrying pilgrims and bereaved families who scatter ashes in the river after performing cremations.

He recently purchased his first smartphone to download music and exchange videos with friends, and promote his boat business to tourists on Facebook.

But he said the government needed to pay equal attention to the municipal services in a city where cars, rickshaws and carts fight for space through narrow, potholed roads lined with litter. Varanasi remains dependent on a 500-year-old, leaky drainage system for its sewage.

"Free Wi-Fi is a good facility for tourists but I think the officials should think about cleaning the ghats," said the 20-year-old, referring to the steps down to the river, which are often caked with cow dung.
