Researchers have unearthed a new species of horned dinosaur in Mexico with larger horns that any other species – up to 4 feet long.  The finding has given scientists fresh insights into the ancient history of western North America, according to a research team led by paleontologists from the Utah Museum of Natural History at the University of Utah.

"We know very little about the dinosaurs of Mexico, and this find increases immeasurably our knowledge of the dinosaurs living in Mexico during the Late Cretaceous," said Mark Loewen, a paleontologist with the Utah Museum of Natural History and lead author of the study.

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).

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.
