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
Tiny Protozoa May Hold Key to World Water Safety Wednesday, December 29, 2010 - 00:00
revolutionary Swimming Behavioral Spectrophotometer (SBS), which employs one-celled protozoa to detect toxins in water sources.
Heat shock protein drives yeast evolution Wednesday, December 29, 2010 - 00:00
Heat shock protein 90 (Hsp90) can create heritable traits in brewer’s yeast (Saccharomyces cerevisiae) by affecting a large portion of the yeast genome. The finding has led to the conclusion that Hsp
