Can dragonflies migrate thousands of miles across the Indian Ocean, from India via the Maldives to Africa, and back again? An international research team led by Lund University in Sweden has used models and simulations to find out if the … Read More

Scientists discover 14 genes that cause obesity: Findings could decouple overeating from harmful health effects

|

Promising news in the effort to develop drugs to treat obesity: University of Virginia scientists have identified 14 genes that can cause and three that can prevent weight gain. The findings pave the way for treatments to combat a health … Read More

Mars’ surface shaped by fast and furious floods from overflowing craters

|

On Earth, river erosion is usually a slow-going process. But on Mars, massive floods from overflowing crater lakes had an outsized role in shaping the Martian surface, carving deep chasms and moving vast amounts of sediment, according to a new … Read More

Great apes’ consonant and vowel-like sounds travel over distance without losing meaning

|

Scientists have shown that orangutan call signals believed to be closest to the precursors to human language, travel through forest over long distances without losing their meaning. This throws into question the accepted mathematical model on the evolution of human … Read More

Happiness in early adulthood may protect against dementia: Depressive symptoms increase risk for cognitive impairment

|

While research has shown that poor cardiovascular health can damage blood flow to the brain increasing the risk for dementia, a new study led by UC San Francisco indicates that poor mental health may also take its toll on cognition. … Read More

Major ocean current could warm greatly

|

A new study led by researchers at Binghamton University, State University of New York found that the Kuroshio Current Extension is sensitive to global climate change and has the potential to warm greatly with increased carbon dioxide levels. Ocean currents … Read More
