Scientist says New Zealand's biggest glacier shrinking 24 Apr 08, 18:13 ET AP - New Zealand's biggest glacier is melting at its fastest pace in recent history, a scientist said Thursday. The Tasman Glacier on South Island was 18 miles long in 1990, with virtually no lake at its front edge, Massey University glacier expert Martin Brook said. more Protein scraps help fill in dino family tree 24 Apr 08, 17:04 ET Reuters - Scraps of protein from the bones of a 68 million-year-old dinosaur and a mastodon carcass confirm their places in the family tree of life on Earth, researchers reported on Thursday. more Mars Features Resemble Hydrothermal Springs 24 Apr 08, 15:02 ET SPACE.com - There's a growing buzz in the astrobiology community that ancient hydrothermal springs may have been spotted on Mars. more Mars Rover's Robotic Arm Glitch Worsens 24 Apr 08, 15:02 ET SPACE.com - A motor glitch has resurfaced aboard NASA's Mars rover Opportunity and may hinder some of the long-lived robot's ability to wield its mechanical arm. more Two Evils Compete: Global Warming vs. Ozone Hole 24 Apr 08, 14:40 ET LiveScience.com - The evils of global warming and ozone depletion are competing problems, at least in Antarctica, the results of two new studies suggest. Schemes to pump sulfur into the atmosphere to counteract global warming might help cool the Earth, but they could also cause problems at the poles, scientists warned today. Continuous injections could drastically deplete polar ozone, delaying the recovery of the current ozone hole over Antarctica by several decades. And another study finds that if the southern ozone hole is patched, the heat would turn on in Antarctica. ... more Gunk in T. Rex Fossil Confirms Dino-Bird Lineage 24 Apr 08, 14:16 ET LiveScience.com - Tyrannosaurus rex just got a firm grip on the animal kingdom s family tree, right next to chickens and ostriches. New analyses of soft tissue from a T.rex leg bone re-confirm that birds are dinosaurs closest living relatives. more German team finds new way to fight Alzheimer's 24 Apr 08, 14:14 ET Reuters - A new kind of drug designed to "hitch-hike" into cells reversed signs of Alzheimer's disease when injected into the brains of mice and may become a potent new treatment for humans, German scientists said on Thursday. more Scientists study evidence modern birds came from dinosaurs 24 Apr 08, 14:03 ET AP - It looks like chickens deserve more respect. Scientists are fleshing out the proof that today's broiler-fryer is descended from the mighty Tyrannosaurus rex. And, not a surprise, they confirmed a close relationship between mastodons and elephants. more Using chemicals to cut global warming may damage ozone layer 24 Apr 08, 14:01 ET AP - The rule of unintended consequences threatens to strike again. Some researchers have suggested that injecting sulfur compounds into the atmosphere might help ease global warming by increasing clouds and haze that would reflect sunlight. more Desalting seawater to meet water needs may hold promise 24 Apr 08, 12:05 ET AP - There's probably a place for desalted seawater in meeting the nation's future water needs, but research is needed to reduce the costs and impact on the environment, the National Research Council says. more Study says near extinction threatened people 24 Apr 08, 12:04 ET AP - Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests. more How DNA Could Reveal Texas Sex Practices 24 Apr 08, 11:05 ET LiveScience.com - Officials in Texas just finished collecting cheek-swab samples from the 437 children and alleged parents in order to determine who is related to whom. more Experts say sex abstinence program doesn't work 24 Apr 08, 10:52 ET Reuters - Programs teaching U.S. schoolchildren to abstain from sex have not cut teen pregnancies or sexually transmitted diseases or delayed the age at which sex begins, health groups told Congress on Wednesday. more Hubble telescope captures crashing galaxies 24 Apr 08, 10:01 ET Reuters - Images of colliding galaxies show them spinning, sliding and slipping into one another, wreaking stellar destruction that will give birth to new and larger galaxies. more Hubble Photographs Dozens of Colliding Galaxies 24 Apr 08, 09:15 ET SPACE.com - A huge set of new Hubble Space Images show galactic collisions in action and the variety of peculiar forms that merging galaxies can take. more Dead Hawk's Last Meal Claws Partway Out 24 Apr 08, 09:10 ET LiveScience.com - A hawk was found dead along a California highway with the claw of a songbird protruding from its chest. more India to blast satellite into space 24 Apr 08, 08:46 ET AFP - An Indian rocket will next week launch an advanced remote-sensing satellite that will help plan and implement urban and rural development projects, the space agency said Thursday. more Gasping for Breath in the Jurassic Era 24 Apr 08, 07:02 ET SPACE.com - The debate over climate change and its effects is often headline news. In the near future, scientists are concerned that the Earth will experience a continuing increase in global temperature. New research is showing that even if this increase is only a few degrees, it could have important repercussions for life on our planet. more Radio telescopes capture black hole mid-belch 24 Apr 08, 06:13 ET Reuters - Using powerful radio telescopes, scientists have captured a supermassive black hole just as it was belching out a jet of supercharged particles, offering a first look at how these cosmic jets are formed, they said on Wednesday. more China calls for help on climate change 24 Apr 08, 03:56 ET AP - China called on the international community Thursday to increase the flow of technology to developing countries to help them fight climate change. more New Zealand's largest glacier will disappear: scientists 24 Apr 08, 02:55 ET AFP - New Zealand's largest glacier is shrinking fast due to climate change and will eventually disappear altogether, scientists said Thursday. more
