Unselfish Molecules May Have Helped Give Birth to the Genetic Material of Life
March 8, 2010 One of the biggest questions facing scientists today is how life began. Scientists have discovered that small molecules could have acted as "molecular midwives" in helping the building blocks of ... > full story -
Snowball Earth: New Evidence Hints at Global Glaciation 716.5 Million Years Ago
March 4, 2010 Geologists have found evidence that sea ice extended to the equator 716.5 million years ago, bringing new precision to a "snowball Earth" event long suspected to have taken place around that time. ... > full story -
Strategic Research Program Needed to Determine Whether, How Past Climate Influenced Human Evolution
March 3, 2010 Understanding how past climate may have influenced human evolution could be dramatically enhanced by an international cross-disciplinary research ... > full story -
Genetic Footprint of Natural Selection
March 2, 2010 A further step has been taken towards our understanding of natural selection. Scientists in France have shown that humans, and some of their primate cousins, have a common genetic footprint -- i.e., ... > full story -
Ancient DNA from Rare Fossil Reveals That Polar Bears Evolved Recently and Adapted Quickly
March 1, 2010 DNA from a rare, ancient polar bear fossil is yielding information about the response of the species to the devastation wrought by past climate changes. Analyses of the fossil's DNA reveals key ... > full story -
By Tracking Water Molecules, Physicists Hope to Unlock Secrets of Life
February 27, 2010 The key to life as we know it is water, a tiny molecule with some highly unusual properties, such as the ability to retain large amounts of heat and to lose, instead of gain, density as it ... > full story -
DNA Sequence of Extinct Ancient Cattle Uncovered
February 27, 2010 Researchers, based in Ireland and Britain, have found the complete mitochondrial DNA genome sequence of ancient wild cattle using a sample from a 6,700 year-old ... > full story -
Stickleback Genomes Shining Bright Light on Evolution
February 25, 2010 Twenty billion pieces of DNA in 100 small fish have opened the eyes of biologists studying evolution. After combining new technologies, researchers now know many of the genomic regions that allowed ... > full story -
Interactions Between Species: Powerful Driving Force Behind Evolution?
February 25, 2010 Scientists in the UK have provided the first experimental evidence that shows that evolution is driven most powerfully by interactions between species, rather than adaptation to the ... > full story -
Small Dogs Originated in the Middle East, Genetic Study Finds
February 23, 2010 A genetic study has found that small domestic dogs probably originated in the Middle East more than 12,000 years ago. Researchers have traced the evolutionary history of the IGF1 gene, finding that ... > full story
