Genomic and computational tools provide window to distant past
Out of the estimated 23,000 or more genes in the human genome, about 100 of them will differ—they will be present or not—between any two individuals. Genes lost or gained over time result from evolution and adaptation, ...

Birds outpace climate change to avoid extinction
A new study has shed light on the potential of birds to survive in the face of climate change. In the analysis, based on more than fifty years' detailed study of a population of great tits near Oxford, UK, a team of scientists ...

Biological fitness trumps other traits in mating game
When a new species emerges following adaptive changes to its local environment, the process of choosing a mate can help protect the new species' genetic identity and increase the likelihood of its survival. But of the many ...

Researchers find little correlation between microbial gene expression and environmental conditions in the laboratory
A new study challenges the orthodoxy of microbiology that in response to environmental changes, bacterial genes will boost production of needed proteins and decrease production of those that aren't. Researchers with the U.S. ...

Genetic switches play big role in human evolution
(Phys.org) —A Cornell study offers further proof that the divergence of humans from chimpanzees some 4 million to 6 million years ago was profoundly influenced by mutations to DNA sequences that play roles in turning genes ...

Bacterium uses natural 'thermometer' to trigger diarrheal disease, scientists find
How does the bacterium Shigella—the cause of a deadly diarrheal disease—detect that it's in a human host? Ohio University scientists have found that a biological "RNA thermometer" monitors whether the environment is right ...
