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, ...

Charles Walters, founder and long-time editor of ACRES USA, the monthly journal of eco-agriculture, has revised and expanded his now classic text on the secrets that weeds reveal to us about our soil. For a thorough undersanding of the conditions that produce certain weeds, you simply can't find a better source than this one -- certainly not one as entertaining, as full of anecdotes and home-spun common sense. The book is a treasury of knowledge, exploring the workings of soil eco-systems through the findings of such giants as William A. Albrecht, C.J. Fenzau and Philip S. Callahan. It contains a lifetime of collected wisdom that teaches us how to udnerstand and thereby control the ...

Anthem, Arizona, is a town north of Phoenix founded ten years ago. It now has a population of 40,000. To ensure that it's water and wastewater are as clean as possible, the town sought to avoid chemical treatments and recently installed an ultraviolet (UV) water disinfection system. Two local golf courses are also using the UV-treated wastewater for irrigation. Two closed-chamber, medium pressure UV systems handle 7 million gallons per day of drinking water and 3 MGD of wastewater. The system, manufactured by Aquionics Inc., of Erlanger, Kentucky, reduces the towns dependence on chlorination, thereby minimizing output of chlorine by-products. It requires minimal maintenance and ...

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 ...

Who needs environmental monitoring? Contact: Annie Drinkard annie@esa.org Ecological Society of America We monitor the stock market, the weather, our blood pressure. Yet environmental monitoring is often criticized as being unscientific, expensive, and wasteful. Scientists argue that environmental monitoring is a crucial part of science in the review, “Who needs environmental monitoring"” Gary Lovett (Institute of Ecosystem Studies) and colleagues from several universities and US government offices contributed to the review. The review is particularly relevant, given the budgetary constraints on current monitoring and the ongoing debate regarding the opportunities, ...

Organic Food Miles take toll on environment Contact: Bev Betkowski beverly.betkowski@ualberta.ca 780-492-3808 University of Alberta Organic fruit and vegetables may be healthier for the dinner table, but not necessarily for the environment, a University of Alberta study shows. The study, conducted by a team of student researchers in the Department of Rural Economy at the University of Alberta in Edmonton, Canada, showed that the greenhouse gas emitted when the produce is transported from great distances mitigates the environmental benefits of growing the food organically. “If you’re buying ‘green’, you should consider the distance the food travels. If it’s ...

Twenty-four new species found in Suriname June 04 2007 at 11:19PM By Deborah Zabarenko Washington - A purple fluorescent frog is one of 24 new species found in the South American highlands of Suriname, conservationists reported on Monday, warning that these creatures are threatened by illegal gold mining. The discovery of so many species outside the insect realm is extraordinary and points up the need to survey distant regions, said Leeanne Alonso of Conservation International, which led the expedition that found the new species. "When you go to these places that are so unexplored and so remote, we do tend to find new species... but most of them are insects," ...

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.

Wayward Whales May Have Reached Ocean MARCUS WOHLSEN | May 30, 2007 02:08 PM EST SAN FRANCISCO — Two lost whales last spotted near the Golden Gate Bridge may have slipped back into the Pacific Ocean after a two-week sojourn that took them 90 miles inland up the Sacramento River, scientists said Wednesday. Rescuers launched several boats Wednesday morning in an effort to find the mother humpback and her calf but hadn't found them, said Bernadette Fees, deputy director of the California Department of Fish and Game. The pair were last seen Tuesday night in San Francisco Bay, where few obstacles were left on their route past Alcatraz to the ocean. "The assumption is if we ...

The Defense Department reports China is building cyberwarfare units and developing viruses. The People's Liberation Army (PLA) continues to build cyberwarfare units and develop viruses to attack enemy computer systems as part of its information-warfare strategy, the U.S. Department of Defense (DOD) warned in a report released on Friday. "The PLA has established information warfare units to develop viruses to attack enemy computer systems and networks," the annual DOD report on China's military warned. At the same, Chinese armed forces are developing ways to protect its own systems from an enemy attack, it said, echoing similar warnings made in previous years. These ...

Retired TV station owner and broadcast engineer, John Kanzius, wasn't looking for an answer to the energy crisis. He was looking for a cure for cancer. Four years ago, inspiration struck in the middle of the night. Kanzius decided to try using radio waves to kill the cancer cells. His wife Marianne heard the noise and found her husband inventing a radio frequency generator with her pie pans. "I got up immediately, and thought he had lost it." Here are the basics of John's idea: Radio-waves will heat certain metals. Tiny bits of certain metal are injected into a cancer patient. Those nano-particals are attracted to the abnormalities of the cancer cells and ignore the ...
How Kassam Rockets Work

If you've been watching the news, you know that Israel is under attack once again. This time, the weapon of choice comes from the skies. It is called the Kassam (or Qassam) rocket, and dozens of them have been landing in Israel. In America we have a certain mental image that appears whenever we hear the word "rocket." We tend to think of something big, complex and expensive. We get that impression because we are used to seeing huge moon rockets or billion-dollar space shuttles flying precisely into orbit under the control of thousands of technicians. The Palestinian Kassam rocket is just the opposite. It is small, simple and cheap. The idea is to create an easily ...

In Ky., a monument to creation Kentucky museum discounts centuries of research, critics sayBy Peter SlevinThe Washington PostUpdated: 3:00 a.m. ET May 27, 2007 PETERSBURG, Ky. - At the Creation Museum, a fanciful Eden rises from the void. Adam appears, bearded and handsome, if slightly waxen. Eve emerges from his rib with luxuriant hair and a kindly expression. Trees blossom and creatures frolic, evidence that all started well in God's perfect world.Elsewhere, as the story develops, Cain stands over his slain brother, Abel; life-size workmen build a replica of Noah's ark, and Methuselah intones: "With each passing day, judgment draws nearer. . . .

Passengers, Not Just Mobile Phones, Contribute To Road Accidents Science Daily — New research by Australian scientists has shown that drivers carrying two or more passengers are twice as likely to crash as unaccompanied drivers. Both the carrying of passengers, and having a larger number of passengers in the car, are associated with an increased likelihood of a crash, though not to the same extent as mobile phone use. The new study, by The George Institute for International Health, was designed to determine the risk of a crash associated with passenger carriage compared with that of using a mobile phone while driving. Both the carrying of passengers, and having a larger number ...

House of Cards Antigua and Barbuda - a nation of 70,000 in an area roughly half the size of San Francisco - has formally requested that the WTO allow it to suspend its intellectual property obligations to the United States, AP reports. Although many in the US have mocked tiny Antigua'a case against the US with a shrug of the shoulders, the Antiguans have always carried in their pockets a nuclear option of sorts. Most Americans view trade disputes through the prism of tit-for-tat protectionist schemes. A perceived price subsidy leads to retaliatory tariffs, etc; but the obligations imposed by WTO obligations run deeper than that. Click here to find out more! Repeated violation of WTO ...
