Astronomers have long suspected that water should exist in the atmospheres of extrasolar planets. Now they have evidence. Water has been discovered in a planet called HD209458b, which was previously found to have oxygen. From the article: 'The discovery ... means one of the most crucial elements for life as we know it can exist around planets orbiting other stars.' But don't go looking for little green men. You might remember HD209458b as a 'hot jupiter' that boils under the glow of its very nearby star.

Computerized projections in sports are nothing new, but Bruce Bukiet of the New Jersey Institute of Technology has developed a model that seems to work pretty well. He projects how many games a Major League Baseball team will win by factoring in how each hitter ought to do against each pitcher in every game. His crystal ball says the Yankees will win 110 games this year, a pretty safe bet, many might agree. But he also projects all the divisional winners. He claims to be right more than wrong in five of the past six years.

Thirty years ago, Luke Skywalker saw what scientists are just now realizing, that double sunsets are likely common in the universe. Astronomers have long known that binary star systems are common. And models suggested that planets could form in these systems, even though there's a double-tug of gravity on the material that would have to form a planet. Observations from NASA's Spitzer telescope, show that binary systems are just as likely to be surrounded by planet-forming debris disks are are lone stars.

Esmail Zanjani and colleagues at the University of Nevada-Reno have created sheep that are 15 percent human at the cellular level. Half the organs in the sheep are human. The idea, of course, is to harvest those organs to transplant into human patients. From the article: ;He has already created a sheep liver which has a large proportion of human cells and eventually hopes to precisely match a sheep to a transplant patient, using their own stem cells to create their own flock of sheep.' One scientists worries, however, that the work could lead to new viruses that cross from animals to humans.

Scientists have long puzzled over how some dinosaurs and other creatures survived the asteroid impact that supposedly caused the KT mass extinction 65 million years ago and wiped out all the big dinos. One idea has been that smaller animals, including mammals, could have endured the fallout, the big chill, the subsequent volcanoes, and whatever else by burrowing. Now scientists have come up with the first evidence of burrowing dinosaurs. They speculate that underground dens might explain how some dinosaurs got through long, dark winters at high latitudes, too.

Playing video games that involve firing guns (Gears of War, Halo, take your pick) can improve eyesight, according to a new study. From the article: 'People who started out as non-gamers and then received 30 hours of training on first-person action video games showed a substantial increase in their ability to see objects accurately in a cluttered space, compared to non-gamers given the same test.' The games push the brain to the limit, the thinking goes, and it adapts by developing better spatial resolution. The effect was not duplicated in sedate games like Tetris.

Seismic observations reveal a huge reservoir of water in Earth's mantle beneath Asia. It's actually rock saturated with water, but it's an ocean's worth of water ... as much as is in the whole Arctic Ocean. How did it get there? A slab of water-laden crust sank, and the water evaporated out when it was heated, and then it was trapped, the thinking goes. The discovery fits neatly with the region's heavy seismic activity and fits neatly with the idea that the planet's moving crustal plates are lubricated with water.

Space.com is reporting that the aging observatory's primary camera, the ACS, has been in safe mode since the weekend. From the article: 'An initial investigation indicates the camera has stopped functioning, and the input power feed to its Side B electronics package has failed.' The camera has shut down before and been revived.

A new study finds those who won Nobel Prizes between 1901 and 1950 lived about 2 years longer than nominees who didn't win. The researchers conclude that the instantly conferred social status leads to health benefits. From the story: 'The research rules out the possibility that intervening prize-related money itself adds the years through improved prosperity.' If you're thinking of aiming for the prize, pick the right field. Nobel laureates in physics lived nearly a year longer than winners in chemistry.

The "Pillars of Creation," made iconic by the Hubble Space Telescope in one of the most widely recognized astronomy image ever taken, may already have toppled. A new image suggests a supernova has likely torn the pillars down, but the light from the event hasn't gotten here yet. From the story: 'Astronomers think the supernova's shock wave knocked the pillars down about 6,000 years ago. But because light from that region of the sky takes 7,000 years to reach us, the majestic pillars will appear intact to observers on Earth for another 1,000 years or so.'

Researchers for at least two decades have used acoustic levitation to suspend light materials without a container. Wenjun Xie, a materials physicist at Northwestern Polytechnical University in China, has previously used ultrasound fields to levitate globs of iridium and mercury, very heavy materials. Now the scientist has performed the feat with live animals. From the story: 'Xie and his colleagues employed an ultrasound emitter and reflector that generated a sound pressure field between them. The emitter produced roughly 20-millimeter-wavelength sounds, meaning it could in theory levitate objects half that wavelength or less.' Apparently the ants, spiders and ladybugs endured the trick just fine, but the fish died from lack of water.

LiveScience is reporting out of NextFest on a Japanese-built power suit that amplifies the strength of its wearer. The onboard computer is hooked up to sensors that monitor natural movements, then it inflates cuffs to boost lifting power. The Power Assist Suit could be used by hospital workers to move heavy patients, the researchers say.

SPACE.com reports that the American Astronomical Unions Division of Planetary Scientists recognizes the IAU's authority to make a new planet defintion but expects it to be altered. Separately, 300 astronomers have signed a petition saying they won't use the definition. All this stems from the discontent over how only 424 astronomers voted on the proposal that demoted Pluto. Looks like this little dog is on the comeback trail.

Earth's moon is drifting away from us more than an inch every year. In a few billion years, if the system survives, the moon would be reclassified as a planet under the new IAU definition. You gotta wonder if the astronomers who dreamed this definition up had thought of that.
