Some people are born vegetarians and ignoring their genetic preference imperils their health, study finds
http://news.nationalpost.com/health/some...tudy-finds
EXCERPT: Why is it that some people can stay healthy only by sticking to a strict vegetarian diet? Why is it that others can eat a steak a day, remain slim, avoid heart disease and feel like a million dollars? The answers may lie in your heritage. Cornell University researchers have found a fascinating genetic variation that they said appears to have evolved in populations that favored vegetarian diets over hundreds of generations....
Scientists grow a beating heart with adult stem cells

EXCERPT: . . . researchers at Massachusetts General Hospital have developed a method that scrubs away the components of a donor heart that could trigger an immune response and rebuilds the heart with stem cells derived from adult skin cells. In a transplant, those stem cells would come from the recipient’s own skin cells, further reducing the risk of rejection....
Stop Making Fun of Tyrannosaurs’ Tiny Arms

EXCERPT: . . . While the smaller arms of dinosaurs like Tyrannosaurus and Ceratosaurus might be good for a laugh, Habib notes that there are biomechanical reasons why smaller limbs may have the advantage. “The bones of the chest and shoulder, such as the coracoids and scapula, are anchor points for muscles going into the arm,” Habib says, “but they are also anchor points for neck muscles.” Only so much muscle can attach to any given bone. But by reducing the size of the arms and the muscles needed to move them, evolution may have allowed dinosaurs like Tyrannosaurus to allot more space to the neck muscles that gave them devastating bites....
