Science News Magazine WASHINGTON, D.C. — Astronomers have for the first time traced gamma rays, the most energetic form of light, to galaxies undergoing a frenzy of star birth. The finding, which has revealed a new class of galactic gamma-ray sources, is not unexpected. But it provides new hints about the origin of many cosmic rays, the hig...h-speed protons and other charged particles of extraordinarily high energies that bombard Earth...

Male bed bugs get confused in bed. Now a scientist has found a bug chemical signal that translates, “Whoa, buddy. I’m a guy too.”
Male bed bugs grasp and try to mate with any other member of their Cimex lectularius species that has had a full meal of blood recently, says chemical ecologist Camilla Ryne of Lund Universit...y in Sweden. Single-minded males don’t seem inclined, or even able, to distinguish other males from females at first...

What do chicken pox, the common cold, the flu, and AIDS have in common? They’re all diseases caused by viruses, tiny microorganisms that can pass from person to person. It’s no wonder that when most people think about viruses, finding ways to steer clear of viruses is what’s on people’s minds.
Not everyone runs from the... tiny disease carriers, though. In Cambridge, Massachusetts, scientists have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work, teaching them to build some of the world’s smallest rechargeable batteries.

Science News Magazine There may be a strange, slithering invasion coming from the South. Big snakes like anacondas, boa constrictors and pythons now live in the wilds of southern Florida. Although not originally native to the United States, some of them are now being born there. Most were people’s pets (or the offspring of pets) that got to...o big, leading the owners to release them into the wild. So far, the snakes have stayed put. But there’s nothing stopping them from moving farther north...

It sounds like a science experiment designed by Willy Wonka: Take a lot of junk food, feed it to some rats, and see what happens.
Scientist Paul Johnson of the Scripps Research Institute and his team did just that. But their science experiment was no fiction. They had a serious goal: to try to understand how parts of the brain play a role in obesity...

Science News Magazine A cell in the eye may be worth two in the beak, at least when it comes to a migratory bird’s magnetic compass. In European robins, a visual center in the brain and light-sensing cells in the eye — not magnetic sensing cells in the beak — allow the songbirds to sense which direction is north and migrate correctly, a new... study finds. The study, appearing October 29 in Nature, may improve conservation efforts for migratory birds...
