Darwin meets Facebook
Natural history plans to chart life on earth, yet the discipline risks being buried under a landslide of painstakingly collected data that isn't always used. view more (2009-11-10)
Why nice guys usually get the girls
Female water striders often reject their most persistent and aggressive suitors and prefer the males who aren't so grabby, according to new research. Water striders are insects commonly seen skittering across the surface of streams. view more (2009-11-06)
Study sheds light on evolution of human complexity
A painstaking analysis of thousands of genes and the proteins they encode shows that human beings are biologically complex, at least in part, because of the way humans evolved to cope with redundancies arising from duplicate genes. view more (2009-11-04)
Inconspicuous leaf beetles reveal environment's role in formation of new species
Unnoticed by the nearby residents of St. Johnsbury, Vermont, tiny leaf beetles that flit among the maple and willow trees in the area have just provided some of the clearest evidence yet that environmental factors play a major role in the formation of new species. view more (2009-11-02)
New American Chemical Society podcast: Tiny sea creature and a new medical adhesive
Scientists questing after a long-sought new medical adhesive describe copying the natural glue secreted by a tiny sea creature called the sandcastle worm in the latest episode in the American Chemical Society's (ACS) award-winning podcast series, "Global Challenges/Chemistry Solutions." view more (2009-10-28)
Scientists discover largest orb-weaving spider
Researchers from the United States and Slovenia have discovered a new, giant Nephila species (golden orb weaver spider) from Africa and Madagascar and have published their findings in the Oct. 21 issue of the journal PLoS ONE. view more (2009-10-21)
Melanoma treatment options 1 step closer
A targeted chemotherapy for the treatment of skin cancer is one step closer, after a team of University of Alberta researchers successfully synthesized a natural substance that shows exceptional potential to specifically treat this often fatal disease. view more (2009-10-21)
Are humans still evolving? Absolutely, says a new analysis of a long-term survey of human health
Although advances in medical care have improved standards of living over time, humans aren't entirely sheltered from the forces of natural selection, a new study shows. view more (2009-10-20)
Fish vision discovery makes waves in natural selection
Emory University researchers have identified the first fish known to have switched from ultraviolet vision to violet vision, or the ability to see blue light. The discovery is also the first example of an animal deleting a molecule to change its visual spectrum. view more (2009-10-19)
Time in a bottle: Scientists watch evolution unfold
A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers said. view more (2009-10-19)
Homebound termites answer 150-year-old evolution question
Staying at home may have given the very first termite youngsters the best opportunity to rule the colony when their parents were killed by their neighbors. view more (2009-10-06)
In amoeba world, cheating doesn't pay
Cheaters may prosper in the short term, but over time they seem doomed to fail, at least in the microscopic world of amoebas where natural selection favors the noble. view more (2009-10-02)
Getting plants to rid themselves of pesticide residues
Scientists in China have discovered that a natural plant hormone, applied to crops, can help plants eliminate residues of certain pesticides. The study is in the current issue of ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. view more (2009-10-01)
Erie County home to plant never before recorded in Pa.
Western Pennsylvania Conservancy (WPC) scientists have discovered a plant in Erie County that has never been recorded in Pennsylvania. view more (2009-09-28)
Dandelion rubber
Most natural rubber comes from rubber trees in Southeast Asia, but this source is now under threat from a fungus. Researchers have optimized the Russian dandelion to make it suitable for large-scale rubber production. view more (2009-09-11)
Getting plants to rid themselves of pesticide residues
Scientists in China are reporting the "intriguing" discovery that a natural plant hormone, applied to crops, can help plants eliminate residues of certain pesticides. view more (2009-09-10)
Study of huge numbers of genetic mutations point to oxidative stress as underlying cause
A study that tracked genetic mutations through the human equivalent of about 5,000 years has demonstrated for the first time that oxidative DNA damage is a primary cause of the process of mutation - the fuel for evolution but also a leading cause of aging, cancer and other diseases. view more (2009-09-08)
Over time, an invasive plant loses its toxic edge
Like most invasive plants introduced to the U.S. from Europe and other places, garlic mustard first found it easy to dominate the natives. A new study indicates that eventually, however, its primary weapon - a fungus-killing toxin injected into the soil - becomes less potent. view more (2009-09-01)
Planned home birth with registered midwife as safe as hospital birth
The risk of infant death following planned home birth attended by a registered midwife does not differ from that of a planned hospital birth. view more (2009-08-31)
Mice living in sandy hills quickly evolved lighter coloration
In a vivid illustration of natural selection at work, scientists at Harvard University have found that deer mice living in Nebraska's Sand Hills quickly evolved lighter coloration after glaciers deposited sand dunes atop what had been much darker soil. The work is described this week in the journal Science. view more (2009-08-28)
