Wolf In Dog's Clothing? Black Wolves May Be First 'Genetically Modified' Predators:
Slipping through trees or across snow, the wolf has glided into legend on paws of white, gray or -- in North America -- even black. This last group owes an unexpected debt to the cousins of the domestic dog, say Stanford researchers. In an unconventional evolutionary twist, dogs that bred with wolves thousands of years ago ceded a genetic mutation encoding dark coat color to their former ancestors. As a result, the Gray Wolf, or Canis lupus, is no longer just gray.
'Nonsense' In Our Genes: One In 200 Human Genes Superfluous?:
1 in 200 of our human genes can be inactivated with no detectable effect on our health. A study by Wellcome Trust Sanger Institute scientists raises new questions about the effects of gene loss on our wellbeing and evolution.
Effect Of Colors: Blue Boosts Creativity, While Red Enhances Attention To Detail:
A new University of British Columbia study reconciles a debate that has long raged among marketers and psychologists: What colour most improves brain performance and receptivity to advertising, red or blue?
Collapse Of Antarctic Ice Sheet Would Likely Put Washington, D.C. Largely Underwater:
University of Toronto and Oregon State University geophysicists have shown that should the West Antarctic Ice Sheet collapse and melt in a warming world - as many scientists are concerned it will - it is the coastlines of North America and of nations in the southern Indian Ocean that will face the greatest threats from rising sea levels.
Interested Or Deceptively Flirting? Observers Of First Dates Can Predict Outcome, Study Shows:
When it comes to assessing the romantic playing field -- who might be interested in whom -- men and women were shown to be equally good at gauging men's interest during an Indiana University study involving speed dating -- and equally bad at judging women's interest.
Rapidly Evolving Gene Contributes To Origin Of Species:
A gene that helped one species split into two species shows evidence of adapting much faster than other genes in the genome, raising questions about what is driving its rapid evolution.
Genetic Adaptations Are Key To Microbe's Survival In Challenging Environment:
The research focused on the bacterium Nautilia profundicola, a microbe that survives near deep-sea hydrothermal vents. Photosynthesis cannot occur in this dark environment, where hot, toxic fluids oozing from below the seafloor combine with cold seawater at very high pressures.
