New discovery proves 'selfish gene' exists
A new discovery by a scientist from The University of Western Ontario provides conclusive evidence which supports decades-old evolutionary doctrines long accepted as fact. view more (2008-06-23)
Newly Compiled Online Bee Checklist Allows Biologists To Link Important Information About All Bee Species
n time for National Pollinator Week, June 22 through June 28, biologists have completed an online effort to compile a world checklist of bees. They have identified nearly 19,500 bee species worldwide, about 2,000 more than previously estimated. view more (2008-06-19)
Bee species outnumber mammals and birds combined
Scientists have discovered that there are more bee species than previously thought. In the first global accounting of bee species in over a hundred years, John S. Ascher, a research scientist in the Division of Invertebrate Zoology at the American Museum of Natural History, compiled online species pages and distribution maps for more than 19,200... view more...

Honeybee dance breaks down cultural barrier
Asian and European honeybees can learn to understand one another's dance languages despite having evolved different forms of communication, an international research team has shown for the first time. The findings are published this week in the journal PLoS ONE. view more (2008-06-04)
Fatal mine collapse covered 50 acres
New calculations show that the deadly Crandall Canyon mine collapse - which registered as a magnitude-3.9 earthquake - began near where miners were excavating coal and quickly grew to a 50-acre cave-in, University of Utah seismologists say in a report on the tragedy. view more (2008-06-02)
CSI: Milky Way team works scene of dead star
Like a team of forensic detectives in a television show that could be called "CSI: Milky Way," a University of Chicago astrophysicist and his associates are piecing together how a mysterious infrared ring got left around a dead star that displays a magnetic field trillions of times more intense than Earth's. view more (2008-05-29)
Supernova birth seen for first time
Astronomers have seen the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time. view more (2008-05-22)
Bacterial slime helps cause serious disease
Leptospirosis is a serious but neglected emerging disease that infects humans through contaminated water. Now research published in the May issue of the journal Microbiology shows for the first time how bacteria that cause the disease survive in the environment. view more (2008-05-05)
Are sacrificial bacteria altruistic or just unlucky?
An investigation of the genes that govern spore formation in the bacteria B. subtilis shows that chance plays a significant role in determining which of the microbes sacrifice themselves for the colony and which go on to form spores. view more (2008-04-16)
Antarctic ice shelf disintegrating as result of climate change, say scientists
Satellite imagery from the University of Colorado at Boulder's National Snow and Ice Data Center shows a portion of Antarctica's massive Wilkins Ice Shelf has begun to collapse because of rapid climate change in a fast-warming region of the continent. view more (2008-03-26)
Royal corruption is rife in the ant world
Far from being a model of social co-operation, the ant world is riddled with cheating and corruption - and it goes all the way to the top, according to scientists from the Universities of Leeds and Copenhagen. view more (2008-03-12)
The downside of a good idea
Good ideas can have drawbacks. When information is freely shared, good ideas can stunt innovation by distracting others from pursuing even better ideas, according to Indiana University cognitive scientist Robert Goldstone. view more (2008-02-21)
Research uncovers the social dynamics of yellow jackets
Michael Goodisman could be called the Maury Povich of the yellow jacket world. In his laboratory, Goodisman determines the paternity of yellow jackets to study family dynamics within a colony. Even though only one family lives within a colony, each yellow jacket queen mates with several males, creating a complex family tree. view more (2008-02-19)
LSU researchers challenge analyses on sustainability of Gulf fisheries
Louisiana's coastal fisheries produce approximately 25 percent of the total catch by weight in the lower 48 states. With such a substantial portion of the nation's economy dependant on the state of these waters - particularly the Gulf of Mexico region - it comes as no surprise that these fisheries are heavily monitored and scrutinized by... view more...

Microbial 'cheaters' help scientists ID 'social' genes
The first genome-wide search for genes governing social behavior has found that even the simplest social creatures -- the amoebae Dictyostelium discoideum -- have more than 100 genes that help regulate their cooperative behavior. view more (2008-02-14)
Ants and avalanches: Insects on coffee plants follow widespread natural tendency
Ever since a forward-thinking trio of physicists identified the phenomenon known as self-organized criticality---a mechanism by which complexity arises in nature---scientists have been applying its concepts to everything from economics to avalanches. view more (2008-01-24)
Neutron stars can be more massive, while black holes are more rare, Arecibo Observatory finds
Neutron stars and black holes aren't all they've been thought to be. In fact, neutron stars can be considerably more massive than previously believed, and it is more difficult to form black holes, according to new research developed by using the Arecibo Observatory in Arecibo, Puerto Rico. view more (2008-01-15)
Astronomers find record-old cosmic explosion
Using the powerful one-two combo of NASA's Swift satellite and the Gemini Observatory, astronomers from a number of institutions, including Johns Hopkins, have detected a mysterious type of cosmic explosion farther back in time than ever before. view more (2008-01-10)
Insects' 'giant leap' reconstructed by founder of sociobiology
The January 2008 issue of BioScience includes an article by biologist Edward O. Wilson that argues for a new perspective on the evolution of advanced social organization in some ants, bees, and wasps (Hymenoptera). view more (2008-01-02)
Choosing dry or wet food for cats makes little difference
Although society is accustomed to seeing Garfield-sized cats, obese, middle-aged cats can have a variety of problems including diabetes mellitus, which can be fatal. view more (2007-12-04)
