Human activities increasing carbon sequestration in forests Contact: Beverly Law bev.law@oregonstate.edu 541-737-6111 Oregon State University CORVALLIS, Ore. – Human-caused nitrogen deposition has been indirectly “fertilizing” forests, increasing their growth and sequestering major amounts of carbon, a new study in the journal Nature suggests. The findings create a more complex view of the carbon cycle in forests, where it was already known that logging or other stand-replacement events – whether natural or not – create periods of 5-20 years when there is a net release of carbon dioxide from forests to the atmosphere, instead of sequestration as they do later ...

Maggie Fox, Health and Science Editor WASHINGTON (Reuters) - An in-depth examination of the human DNA map has turned basic biology concepts upside-down and may even rewrite the book on evolution and some causes of disease, researchers said on Wednesday. They found there was far more to genetics than the genes themselves and determined there was no such thing as "junk DNA" but that some of the most useless-looking stretches of DNA may carry important information. Thirty-five teams of researchers from 80 different organizations in 11 countries teamed up to share notes on just 1 percent of the human genome. Their findings, the start of the Encyclopedia of DNA Elements or ENCODE ...

Moonlighting in solar For chip manufacturers, wafers 'have been like gold' of late By Matt Andrejczak, MarketWatch Last Update: 12:52 PM ET Jun 13, 2007 SAN FRANCISCO (MarketWatch) -- Not long ago, used chip wafers were considered all but worthless, sent to landfills or recycling centers. But semiconductor makers have found a new home for the millions of wafers they exhaust each year: the emerging solar industry. Amid tight supplies of polysilicon, it's become a worthwhile side business for chip manufacturers such as Texas Instruments Inc. 'Lucrative business' These wafers "have been like gold" for the makers of chips over the past couple years, said Pat ...

Free from the Atmosphere Laser Guide Star System on ESO's VLT Starts Regular Science Operations An artificial, laser-fed star now shines regularly over the sky of Paranal, home of ESO's Very Large Telescope, one of the world's most advanced large ground-based telescopes. This system provides assistance for the adaptive optics instruments on the VLT and so allows astronomers to obtain images free from the blurring effect of the atmosphere, regardless of the brightness and the location on the sky of the observed target. Now that it is routinely offered by the observatory, the skies seem much sharper to astronomers. In order to counteract the blurring effect of Earth's ...

Researchers examine carbon capture and storage to combat global warming Contact: Mark Shwartz mshwartz@stanford.edu 650-723-9296 Stanford University While solar power and hybrid cars have become popular symbols of green technology, Stanford researchers are exploring another path for cutting emissions of carbon dioxide, the leading greenhouse gas that causes global warming. Carbon capture and storage, also called carbon sequestration, traps carbon dioxide after it is produced and injects it underground. The gas never enters the atmosphere. The practice could transform heavy carbon spewers, such as coal power plants, into relatively clean machines with regard to global warming. ...

The woes of Kilimanjaro: Don't blame global warming Contact: Vince Stricherz vinces@u.washington.edu 206-543-2580 University of Washington The "snows" of Africa's Mount Kilimanjaro inspired the title of an iconic American short story, but now its dwindling icecap is being cited as proof for human-induced global warming. However, two researchers writing in the July-August edition of American Scientist magazine say global warming has nothing to do with the decline of Kilimanjaro's ice, and using the mountain in northern Tanzania as a "poster child" for climate change is simply inaccurate. "There are dozens, if not hundreds, of photos of midlatitude ...

Oxygen trick could see organic costs tumble Contact: SCI Press Office press@soci.org 44-020-759-81548 Society of Chemical Industry A simple, cheap treatment using just oxygen could allow growers to store organic produce for longer and go a long way towards reducing the price of organic fruit and vegetables, reports Lisa Richards in Chemistry & Industry, the magazine of the SCI. Currently UK shoppers have to pay twice as much for some organic products. Organic apples, for example, are around double the price of conventionally grown apples in Sainbury’s, Waitrose and Tesco. One of the major contributing factors affecting the price is the short shelf life of organic produce. ...

Rockfish with the disease mycobacteriosis can develop lesions and have their scales destroyed. AP/KATHLEEN LANGE OXFORD, Md. -- Biologist Larry Pieper is wearing waterproof overalls and giving dozens of bass from the Chesapeake Bay a tabletop inspection. He's not surprised by what he sees -- many of them look sick. Pieper is part of Maryland's first effort this year to take a new look at a chronic wasting disease in striped bass, commonly called rockfish or stripers. Mycobacteriosis, also known as "myco" or fish handler's disease, can slowly eat away at a fish's scales. It can leave nasty lesions and kill the striped bass, the hallmark fish of the Chesapeake ...

Mysterious deaths of bees take broad toll As scientists try to explain why colonies are vanishing, worried beekeepers and farmers add up their losses. By Jia-Rui Chong and Thomas H. Maugh II Times Staff Writers June 10, 2007 The dead bees under Dennis vanEngelsdorp's microscope were like none he had ever seen before. He had expected to see mites or amoebas, perennial pests of bees. Instead, he found internal organs swollen with debris and strangely blackened. The bees' intestinal tracts were scarred, and their rectums were abnormally full of what appeared to be partly digested pollen. Dark marks on the sting glands were telltale signs of infection. "The more you looked, ...

Dirty snow may warm Arctic as much as greenhouse gases Burning cleaner fuel would brighten snow and lower temperatures Irvine, Calif., June 6, 2007 The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism – dirty snow – can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases. Snow becomes dirty when soot from tailpipes, smoke stacks and forest fires enters the atmosphere and falls to the ground. Soot-infused snow is darker than natural snow. Dark surfaces absorb sunlight and cause warming, while bright surfaces reflect heat back into space and cause ...

Published: June 2, 2007 at 5:25 PM LONDON, June 2 (UPI) -- Millions of British bank customers were turned away from cash machines empty-handed after systems crashed Friday. The Royal Bank of Scotland, which owns Natwest, had its cards and all RSB services up and working as of Saturday afternoon, but engineers were still furiously working away trying to fix Natwest's Internet and telephone banking network, BBC reported. "We are very sorry, and we're working to sort it out," a bank spokesman told the BBC. The cause of the technological snafu was not immediately clear.
