Oil companies can wave goodbye to their profits: Researchers in the U.K. have built a battery that runs on garbage that can provide electricity for your home. And in France, they’ve developed a car that runs on air. Right now, the fuel cell runs on sugar cubes, since they produce no waste when broken down, but researchers want to run it on carrot power next.

E. coli bacteria (the same kind that gives you a stomach ache) live inside the battery and produce enzymes that break down carbohydrates, releasing hydrogen atoms. The cell also contains chemicals that use these atoms to create voltage that can be used to power an electrical circuit. One cell can light a 40-watt bulb for eight hours on just a few teaspoons of sugar.

Scientists say that adolescent brains are changing so rapidly that they find it hard to process basic information, which leads to emotional and social problems. Their ability to recognize other people’s emotional states is significantly reduced starting at age 11 and doesn’t return to normal until they?re around 18 years old.

For researcher Robert McGivern, this explains why teenagers find life so tough. Studies show that puberty causes sudden increases in the connectivity of nerves in parts of the brain, especially in the prefrontal cortex. “This plays an important role in the assessment of social relationships, as well as planning and control of our social behavior,” says McGivern.

A supermassive black hole is at the center of our Milky Way galaxy that has a mass 3.7 million times that of the Sun. Like all black holes, it has a strong gravitational attraction that sucks in all matter that comes too close?including light. There is evidence that most galaxies have black holes at the center, just like ours. Until recently, black holes were just a theory, and no one could prove they really existed. But now?”We have been able to exclude some still possible alternative configurations…there is nothing left that one would consider realistic and possible, other than a black hole,” says Dr. Reinhard Genzel

Israeli intelligence has discovered that Osama Bin Laden is dead but his heir has been chosen and the terrorist campaign against the U.S. will continue. The new head of al-Qaeda hasn?t been identified, but it’s probably not Bin Laden’s son Saad, who is in his 20s and works within the terror organization. The Israelis think Bin Laden probably died during the U.S. military campaign in Afghanistan in December and that the recent messages from him on video and audio are fakes or earlier recordings. “In this case, it doesn’t matter whether Bin Laden is alive or not,” says a senior Israeli intelligence source. “The organization goes on with help from key people.”
