Evolution picks up hitchhikers - 22/07/2013

In a twist on "survival of the fittest," researchers have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride. These hitchhikers are mutations that do not appear to have a role in contributing...

A bad alliance: Rare immune cells promote food-induced allergic inflammation in the esophagus - 21/07/2013

Until recently, how EoE, a food allergy-associated disease, developed was unclear, but a new study shows that a type of rare immune cell and specific reactions to allergenic foods team up -- in a bad way.

Current efforts will not save the world's most endangered cat - 21/07/2013

Almost 100 million euros has been spent so far on conservation efforts for the last 250 remaining Iberian lynxes in the wild. But the charismatic species is likely to go extinct within 50 years because the current management plans do not account for the effects of climate change. If they did, the population might increase...
