Ancient Raptors Likely Feasted On Early Man, Study Suggests:

A new study suggests that prehistoric birds of prey made meals out of some of our earliest human ancestors. Researchers drew this conclusion after studying more than 600 bones from modern-day monkeys. They had collected the bones from beneath the nests of African crowned eagles in the Ivory Coast’s Tai rainforest. A full-grown African crowned eagle is roughly the size of an American bald eagle, which typically weighs about 10 to 12 pounds.

Red Fish, Blue Fish: Distinctive Color Keeps Gene Pools Healthy:

Long-running evolutionary biology research on fish populations by UC Riverside scientist David Reznick has yielded new findings into how fish keep their gene pools healthy. Female fish tend to choose males with distinctive or rare coloration, thus ensuring that no one genetic line smothers out less common ones.

Dogs And Smog Don’t Mix: Pets In Homes May Lead To Increased Rates Of Bronchitis In Children:

A new study from USC researchers suggests that having a dog in the home may worsen the response to air pollution of a child with asthma.

Sunscreens Can Damage Skin, Researchers Find:

Are sunscreens always beneficial, or can they be detrimental to users? A research team led by UC Riverside chemists reports that unless people out in the sun apply sunscreen often, the sunscreen itself can become harmful to the skin.

How The Body’s T Cells React To Parasitic Diseases:

While scientists understood how T cells worked in certain kinds of diseases, one area has remained murky: disorders caused by protozoan parasites. Now, because of a study just published and led by scientists at the University of Georgia, researchers are closer than ever to understanding how T cells respond to parasitic diseases that kill millions each year.

Researchers Identify Antibiotic Protein That Defends The Intestine Against Microbial Invaders:

Researchers at University of Texas Southwestern Medical Center have identified a protein that is made in the intestinal lining and targets microbial invaders, offering novel insights into how the intestine fends off pathogens and maintains friendly relations with symbiotic microbes.
