Social Interactions Can Alter Gene Expression In Brain, And Vice Versa:
Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.
Playing A Game Shows How Personalities Evolved:
Why do some of us always do the right thing while others only seem to be out for themselves? Research by the universities of Exeter and Bristol offers a new explanation as to why such a wide range of personality traits has evolved in humans and other social species.
Sea Snakes Seek Out Freshwater To Slake Thirst:
Sea snakes may slither in saltwater, but they sip the sweet stuff. So concludes a University of Florida zoologist in a paper appearing this month in the online edition of the November/December issue of the journal Physiological and Biochemical Zoology.
Paleontologists Doubt 'Dinosaur Dance Floor':
A group of paleontologists visited the northern Arizona wilderness site nicknamed a "dinosaur dance floor" and concluded there were no dinosaur tracks there, only a dense collection of unusual potholes eroded in the sandstone.
Tale Of Two Snails Reveals Secrets About The Biochemistry Of Evolution:
Researchers in Spain are reporting deep new insights into how evolution changes the biochemistry of living things, helping them to adapt to new environments. Their study, based on an analysis of proteins produced by two populations of marine snails, reveals chemical differences that give one population a survival-of-the fittest edge for life in its cold, wave-exposed environment.
Unraveling Lion's Natural History Using Host And Virus Population Genomics:
The lion (Panthera leo) is one of the world's most charismatic carnivores. In an article published November 7 in the open-access journal PLoS Genetics, an international team of researchers provides insights into the genetic structure and history of lion populations.
