Researchers Rouse Brain Cells that Control Eating Behavior in Mice Friday, January 7, 2011 - 00:00
By illuminating key nerve cells that regulate feeding behavior, researchers at the Howard Hughes Medical Institute's Janelia Farm Research Campus have discovered how to prod mice to eat voraciously-or
When less is more: how mitochondrial signals extend lifespan Friday, January 7, 2011 - 00:00
Using the roundworm Ceanorhabditis elegans to show that perturbing mitochondrial function in subsets of worm cells sent global signals governing longevity of the entire organism.
Widespread Ancient Ocean "Dead Zones" Challenged Early Life Thursday, January 6, 2011 - 00:00
Persistent lack of oxygen in Earth's oceans affected animal evolution.
Keeping Your Enemies Closer Wednesday, January 5, 2011 - 00:00
Studying the way in which bacteria incorporate foreign DNA from invading viruses into their own regulatory processes is revealing secrets of one of nature's most primitive immune systems. The research
What Triggers Mass Extinctions? Study Shows How Invasive Species Stop New Life Wednesday, January 5, 2011 - 00:00
Collapse of Earth's marine life 378 to 375 million years ago holds key. An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events,
MIT researchers study the danger of toxoplasma parasites Wednesday, January 5, 2011 - 00:00
Biologist Jeroen Saeij shows why some strains are more dangerous than others. About one-third of the human population is infected with a parasite called Toxoplasma gondii, but most of them don't know
If many want to feed: how seabirds share their habitat Wednesday, January 5, 2011 - 00:00
Feeding habits of diving seabirds differ spatially and temporally, both within and between species. When different species of seabirds share a habitat with limited sources of food, they must differ in
Globalisation burdens future generations with biological invasions Thursday, December 30, 2010 - 00:00
A new study on biological invasions based on extensive data of alien species from 10 taxonomic groups and 28 European countries has shown that patterns of established alien species richness are more r
