  • Fresh Genes Needed to Save Chicken Industry
  • The first analysis of genetic diversity in a modern agricultural commodity has returned some disturbing news: Market-driven chicken farming has produced a race of genetically homogeneous fowl in dire need of new blood.
  • Industrial chickens, bred to grow big and fast, have lost about half of the genetic variation found in their wild counterparts. The precise role of each lost variant isn't known, but many likely affect resistance to disease.

  • Five months ago, it landed on the Martian surface — and into our hearts. It gave us soil analysis data, photos of the sky from the red planet, and even hope of extraterrestrial life. Now, with its power deteriorating, its sunlight exposure shrinking, and Martian temperatures dropping to almost -100°C, the Phoenix lander's time may be up. Project manager Barry Goldstein admitted "we're towards the end," and Phoenix even bid us a fond goodbye on its Twitter page. But that's the charm of robots; they never truly die.

  • carbohydrates came into the body as sugars,

  • put them back together to build fats
