Definitive Evidence Found Of A Swimming Dinosaur:

An extraordinary underwater trackway with 12 consecutive prints provides the most compelling evidence to-date that some dinosaurs were swimmers. The 15-meter-long trackway, located in La Virgen del Campo track site in Spain's Cameros Basin, contains the first long and continuous record of swimming by a non-avian therapod dinosaur.

Teen Sex And Depression Study Finds Most Teens' Mental Health Unaffected By Nonmarital Sex:

For a decade, the legislative push for "abstinence only" sex education has suggested that nonmarital sex negatively affects a teen's mental health. But a new study shows that the negative mental side effects of a teen's loss of virginity are confined to a small proportion of those who have sex -- specifically, young girls and both boys and girls who have sex earlier than their peers and whose relationships are uncommitted and ultimately fall apart.

Mother Birds 'Engineer' Their Offspring:

Current research emphasizes the role of maternal effects in fostering the adaptation of organisms to a changing environment. In birds, mothers pass androgens to their eggs, and these hormones have been shown to influence the development and behavior of nestlings. Since these effects may persist in adulthood, it has been suggested that avian mothers may engineer, so to speak, the adult phenotype of their offspring.

Color Vision Drove Primates To Develop Red Skin And Hair, Study Finds:

You might call it a tale of "monkey see, monkey do." Researchers at Ohio University have found that after primates evolved the ability to see red, they began to develop red and orange skin and hair. Humans, apes and Old World monkeys, such as macaques and leaf monkeys, all have trichromatic vision, which allows these primates to distinguish between blue, green and red colors. Primatologists have disagreed about whether this type of color vision initially evolved to help early primates forage for ripe fruit and young, red leaves among green foliage or evolved to help them select mates.

Cannibalism Of The Young Allows Individual Fish To Specialize:

If you go fishing for Arctic char you may end up catching distinctly different-looking individuals although they were all caught in the same lake. Similarly, whitefish, threespine stickleback, and some sunfishes also display quite discrete groups living in the same lakes but utilizing different food resources in order to survive.

Clues To Mysteries Of Physical Attractiveness Revealed:

Score one for body language: It seems that body shape and the way people walk hold major cues to their attractiveness to others, according to collaborative research findings published by Texas A&M University professor Louis G. Tassinary and co-author Kerri Johnson of New York University.

Adult Brain Cells Rediscover Their Inner Child:

You may not be able to relive your youth, but part of your brain can. Johns Hopkins researchers have found that newly made nerves in an adult brain's learning center experience a one-month period when they are just as active as the nerves in a developing child. The study, appearing in Neuron, suggests that new adult nerves have a deeper role than simply replacing dead ones.
