Bug-Zapper: A dose of radiation may help knock out malaria
How are physicists helping an effort to eradicate malaria, the mosquito-borne disease that kills more than one million people every year" Researchers at the National Institute of Standards and Technology (NIST) used their expertise in radiation science to help a young company create weakened, harmless versions of the malaria-causing parasite. view more (2007-11-09)
Researchers announce results of study on genetic variation in Parkinson's disease
Researchers at the National Institutes of Health (NIH) have completed one of the first large-scale studies of the role of common genetic variation in Parkinson's disease (PD). view more (2006-09-28)
Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community richness. In the February issue of Ecology Letters,... view more... (2003-01-28)
Origins of Life
The origin of life lies in unique ocean reefs, and scientists from the University of Miami's Rosenstiel School of Marine & Atmospheric Science have developed an approach to help investigate them better. view more (2006-11-20)
Greenhouse gas bubbling from melting permafrost feeds climate warming
A study co-authored by a Florida State University scientist and published in the Sept. 7 issue of the journal Nature has found that as the permafrost melts in North Siberia due to climate change, carbon sequestered and buried there since the Pleistocene era is bubbling up to the surface of Siberian thaw lakes and into the atmosphere as methane, a... view more...

Why some people are more attractive than others
Researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different? view more (2007-03-28)
Archaeologists find evidence of earliest African slaves brought to new world
In the early European histories of the New World, there are numerous accounts of African slaves accompanying explorers and colonists. view more (2006-02-01)
Study shows largest North America climate change in 65 million years
The largest climate change in central North America since the age of the dinosaurs 65 million years ago, a temperature drop of nearly 15 degrees Fahrenheit, is documented within the fossilized teeth of horses and other plant-eating mammals, a new study reveals. view more (2007-02-08)
A warming climate can support glacial ice
New research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events. view more (2008-01-11)
Why do some queen bees eat their worker bee's eggs?
Worker bees, wasps, and ants are often considered neuter. But in many species they are females with ovaries, who although unable to mate, can lay unfertilized eggs which turn into males if reared. view more (2006-12-05)
Gene variations linked to brain aneurysms
Variations in a gene seem to be linked to brain (cerebral) aneurysms, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-04-27)
Genetic variation: We're more different than we thought
New research shows that at least 10 percent of genes in the human population can vary in the number of copies of DNA sequences they contain-a finding that alters current thinking that the DNA of any two humans is 99.9 percent similar in content and identity. view more (2006-11-27)
Chimpanzee study reveals genome variation hotspots
Researchers believe that dynamic regions of the human genome - "hotspots" in terms of duplications and deletions - are potentially involved in the rapid evolution of morphological and behavioral characteristics that are genetically determined. view more (2006-05-16)
Study rules out ancient 'bursts' of methane from seafloor deposits
A dramatic increase about 12,000 years ago in levels of atmospheric methane, a potent greenhouse gas, was most likely caused by higher emissions from tropical wetlands or from plant production, rather than a release from seafloor methane deposits. view more (2006-08-25)
Human-chimp difference may be bigger
Approximately 6 percent of human and chimp genes are unique to those species, report scientists from Indiana University Bloomington and three other institutions. view more (2006-12-20)
Climate models need deeper roots, scientists say
By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics. view more (2005-12-06)
UCLA scientists strengthen case for life more than 3.8 billion years ago
Ten years ago, an international team of scientists reported evidence, in a controversial cover story in the journal Nature, that life on Earth began more than 3.8 billion years ago-400 million years earlier than previously thought. view more (2006-07-24)
Oldest Known Rock on Earth Discovered
Canadian bedrock more than 4 billion years old may be the oldest known section of the Earth's early crust. view more (2008-09-29)
Doubts raised about illegal drug use surveys
A scientific study reported in two related articles in the Journal of Drug Issues raises serious doubts about the nation's illegal drug use surveillance programs. view more (2006-03-03)
