Super material will make lighting cheaper and fully recyclable (February 6, 2010) -- With the use of the new super material graphene, Swedish and American researchers have succeeded in producing a new type of lighting component. It is inexpensive to produce and can be fully recycled. ... > full story
'Zen' bats hit their target by not aiming at it (February 5, 2010) -- New research shows Egyptian fruit bats find a target by NOT aiming their guiding sonar directly at it. Instead, they alternately point the sound beam to either side of the target. The new findings suggest that this strategy optimizes the bats' ability to pinpoint the location of a target, but also makes it harder for them to detect a target in the first place. ... > full story
Prion leaves lasting mark on memory (February 5, 2010) -- Prions are a special class of proteins best known as the source for mad cow and other neurodegenerative diseases. Despite this negative reputation, a prion may also have important and very positive roles in brain function. The researchers suggest that a prion-like protein may participate in memory in higher eukaryotes, from sea slugs on up. ... > full story
Commercial fishing endangers dolphin populations, new study finds (February 5, 2010) -- Extensive commercial fishing endangers dolphin populations in the Mediterranean, according to a new study by researchers in Israel. ... > full story
How sperm get a move on; discovery suggests new target for male contraception (February 5, 2010) -- Most of us probably think of sperm as rather active little cells, swimming with quick movements of their "tail" or flagella. But actually sperm's motility is in fact short lived. When in the male reproductive tract they have to rest easy, lest they wear themselves out prematurely and give up any chance of ever finding an egg. ... > full story
Engineers aim to make air travel greener (February 5, 2010) -- Carbon emissions from air travel could be reduced, thanks to a new collaboration between engineers in the UK and the aerospace industry. The million project will investigate new ways of using composite materials for wing panels in aircraft. The research will be using carbon fibres that are curved within flat plates to produce damage-tolerant, buckle-free structures. ... > full story
New material absorbs, conserves oil (February 5, 2010) -- Researchers make new material to clean up oil spills in factories or on the ocean, and conserve the oil. ... > full story
Dinosaur had vibrant colors, microscopic fossil clues reveal (February 5, 2010) -- Deciphering microscopic clues hidden within fossils, scientists have uncovered the vibrant colors that adorned a feathered dinosaur extinct for 150 million years. ... > full story
It looks, feels and tastes like chicken, but it's made of soy (February 5, 2010) -- Sure, some delicacies might taste just like chicken, but they usually feel and look much different. Soy meat alternatives, such as the soy burger, have become more popular recently, with increased sales of eight percent from 2007 to 2008. Now, scientists have created a soy substitute for chicken that is much like the real thing. The new soy chicken also has health benefits, including lowering cholesterol and maintaining healthy bones. ... > full story
Oceans reveal further impacts of climate change (February 5, 2010) -- The increasing acidity of the world's oceans -- and that acidity's growing threat to marine species -- are definitive proof that the atmospheric carbon dioxide that is causing climate change is also negatively affecting the marine environment. ... > full story
Video of virus in action shows viruses can spread faster than thought possible (February 5, 2010) -- New video footage of a virus infecting cells is challenging what researchers have long believed about how viruses spread, suggesting that scientists may be able to create new drugs to tackle some viruses. ... > full story
Seabed biodiversity of the Straits of Magellan and Drake Passage (February 5, 2010) -- A study of animals visible to the naked eye and living in and on the seabed -- the "macrobenthos" -- of the Straits of Magellan and Drake Passage will help scientists understand the biodiversity, biogeography and ecology of the Magellanic region. ... > full story
