Revisiting chicxulub
For decades, scientists have accumulated ever-larger datasets that suggest an enormous space rock crashed into the ocean off the Yucatan Peninsula more than 65 million years ago, resulting in the Cretaceous-Paleogene (K-Pg) extinction. view more (2010-03-05)
Scientists find signs of 'snowball Earth' amidst early animal evolution
Geologists have found evidence that sea ice extended to the equator 716.5 million years ago, bringing new precision to a "snowball Earth" event long suspected to have taken place around that time. view more (2010-03-05)
Physical activity in schools can improve children's fitness
A structured physical activity programme at school can improve children's fitness and decrease body fat, a study published on bmj.com today shows. view more (2010-02-24)
Upside-down answer for deep Earth mystery
When Earth was young, it exhaled the atmosphere. During a period of intense volcanic activity, lava carried light elements from the planet's molten interior and released them into the sky. view more (2010-02-18)
The carbon cycle before humans
Geoengineering -- deliberate manipulation of the Earth's climate to slow or reverse global warming -- has gained a foothold in the climate change discussion. view more (2010-02-17)
Mexican-Americans come closest to meeting national physical activity goals
When it comes to meeting national health goals for physical activity, Mexican-Americans are the most active group in America and may benefit from exercise that researchers typically have not measured, according to research by scholars at the University of Chicago and Arizona State University. view more (2010-02-11)
From music to sports: Autonomy fosters passion among kids

Depression saps endurance of the brain's reward circuitry
A new study at the University of Wisconsin-Madison suggests that depressed patients are unable to sustain activity in brain areas related to positive emotion. view more (2009-12-22)
Scientists use light to map neurons' effects on one another
Scientists at Harvard University have used light and genetic trickery to trace out neurons' ability to excite or inhibit one another, literally shedding new light on the question of how neurons interact with one another in live animals. view more (2009-12-18)
Pre-eruption earthquakes offer clues to volcano forecasters
Like an angry dog, a volcano growls before it bites, shaking the ground and getting "noisy" before erupting. This activity gives scientists an opportunity to study the tumult beneath a volcano and may help them improve the accuracy of eruption forecasts, according to Emily Brodsky, an associate professor of Earth and planetary sciences... view more...
