A project under development at the University of Nevada, Reno, called VI Fit can help children who are blind become more physically active and healthy through video games. The human-computer interaction research team in the computer science and engineering department has developed a motion-sensing-based tennis and bowling exergame.

"Lack of vision forms a significant barrier to participation in physical activity and consequently children with visual impairments have much higher obesity rates and obesity-related illnesses such as diabetes," Eelke Folmer, research team leader and assistant professor in the computer science and engineering department, said.

Researchers writing in Science have found the possible source of a huge carbon dioxide 'burp' that happened some 18,000 years ago and which helped to end the last ice age.

The results provide the first concrete evidence that carbon dioxide (CO2) was more efficiently locked away in the deep ocean during the last ice age, turning the deep sea into a more 'stagnant' carbon repository – something scientists have long suspected but lacked data to support.

Working on a marine sediment core recovered from the Southern Ocean floor between Antarctica and South Africa, the international team led by Dr Luke Skinner of the University of Cambridge radiocarbon dated shells left behind by tiny marine creatures called foraminifera (forams for short).

Scientists say ancient fossils unearthed in the Sahara desert belong to a new type of pterosaur (giant flying reptile or pterodactyl) that existed about 95 million years ago. According to the findings published PLoS ONE, the researchers consider the newly identified pterosaur to be the earliest example of its kind.

The scientists have named the new pterosaur Alanqa saharicafrom the Arabic word 'Al Anqa' meaning Phoenix, a mythological flying creature that dies in a fire and is reborn from the ashes of that fire.

Unearthed in three separate pieces, the jaw bone has a total length of 344mm (13.5 inches). Each piece is well preserved, uncrushed, and unlike most other pterosaur fossils, retains its original three dimension shape.

Florida State accounting professor Douglas Stevens says economic decision-makers frequently factor morality into their judgments and behavior, and it's time for economic models to incorporate morality as a result.

Stevens and a colleague have published a paper in Accounting, Organizations and Society that incorporates morality into the economic theory of the firm, known as principal-agent theory. 

A new survey conducted by Virginia Commonwealth University shows that Americans are divided over whether to increase offshore oil drilling, and a majority believes the risks outweigh the benefits.

51 percent of those surveyed said the environmental risks outweigh the benefits; 35 percent think the benefits outweigh the environmental risks. However, opinion among the general population about increasing offshore oil drilling is currently divided with 45 percent in support of increasing offshore drilling and 44 percent opposed.

In order to get the public more involved in the climate change issue, scientists and activists have to move away from fear-laden imagery of drowning polar bears and flooded cities, according to new research published in Meteorological Applications. The paper explores how new 'visual strategies' can communicate climate change messages against a backdrop of increased climate scepticism.
