Cosmic rays believed to start in black holes
November 9, 2007 08:42 AM -
Ultra-high energy cosmic rays -- particles that pack the punch of a rifle shot -- make their way to Earth from massive black holes in nearby galaxies, scientists said on Thursday, in a finding that may solve a mystery that has puzzled physicists for decades.
This sub-atomic matter, they believe, likely breaks free just before stars, gas and dust are gobbled up by the gravitational pull of black holes so dense that not even light can escape.
Rediscovering a Forgotten Landscape And Protecting A Rare Primate
November 8, 2007 05:22 PM - Kerry Bowman, PhD
Congo, Africa - Using state-of-the-art geospacial technology, scientists are mapping one of the last uncharted wilderness regions on the planet, with an eye to protecting the ecosystem that supports the Bonobo chimpanzee, one of our closest evolutionary relatives ane scores of other animals.Located in the remote south east Democratic Republic of Congo, the 56,000-square-kilometre tract of forest remains little known to outsiders. The biological importance of the region—called Tshuapa-Lomami-Lualaba, or TL2 — has been hinted at for more than four decades. But today inventories are being conducted within forest sectors, focusing on areas of interest to monitor the presence of the endangered bonobo chimpanzee, as well as a rich variety of monkey species, okapi, Congo peacock, large ungulates, elephants and much more.
Fuel Cells Gearing Up to Power Auto Industry

The average price for all types of gasoline is holding steady around $2_95 per gallon nationwide, but the pain at the pump might be short-lived as research from the University of Houston may eliminate one of the biggest hurdles to the wide-scale production of fuel cell-powered vehicles.
Australian Scientists Decode Whale Sounds

SYDNEY - Australian scientists studying humpback whales sounds say they have begun to decode the whale's mysterious communication system, identifying male pick-up lines and motherly warnings. Wops, thwops, grumbles and squeaks are part of the extensive whale repertoire recorded by scientists from the University of Queensland working on the Humpback Whale Acoustic Research Collaboration (HARC) project.
Safety agency issues new batch of toy recalls
November 7, 2007 10:13 PM - By Karey Wutkowski, Reuters
WASHINGTON (Reuters) - More recalls of lead-tainted toys made in China were announced on Wednesday by the U.S. Consumer Product Safety Commission, including 380,000 toy cars sold at Dollar General stores.
Other warnings included smaller recalls of Dizzy Ducks music boxes, Winnie-the-Pooh spinning tops, "Big Red" wagons, Dragster and Funny Car toys, and Duck Family collectible wind-up toys, all because of paint with unsafe levels of lead.
Millions of similar toy recalls, most involving Chinese-made products, have alarmed American consumers in recent months. Lead is toxic and can pose serious health risks to children, including brain damage.
Exceptions prove rule of tropical importance in biodiversity
November 7, 2007 09:13 PM -
Even a group of shellfish that appear to violate the overarching pattern of global biodiversity actually follows the same biological rules as other marine organisms, confirming a general theory for the spread of life on Earth. The University of Chicago’s David Jablonski and his colleagues present this finding in the Nov. 7 advanced online edition of the Proceedings of the National Academy of Sciences.
“There’s more of everything in the tropics. More genetic diversity, more diversity in form, more diversity of species,” said David Jablonski, the William R. Kenan Jr. Professor in Geophysical Sciences at Chicago.
Dead clams tell tales, give time-lapse view of ecosystems
November 7, 2007 08:46 PM -
Chicago - Inventories of living and dead organisms could serve as a relatively fast, simple and inexpensive preliminary means of assessing human impact on ecosystems. The University of Chicago’s Susan Kidwell explains how measuring the degree of live-dead mismatch could be used as an ecological tool in the Oct. 26 early online edition of the Proceedings of the National Academy of Sciences.
“We affect ecosystems in many different ways, but the effects of our actions are hard to pin down because we rarely have scientific data from before the onset of those impacts,” said Kidwell, the William Rainey Harper Professor in Geophysical Sciences at Chicago.
Maine officials OK 57 megawatt wind farm on Stetson Mountain
November 7, 2007 08:23 PM - Paul Schaefer, ENN
Boston, MA — A 57 megawatt wind generating farm planned for Stetson Mountain received a critical OK today from Maine officials. UPC Wind, a wind power company, received approval from the Maine Land Use Regulation Commission on a rezoning petition and preliminary plan for the company’s proposed (MW) Stetson Wind Project in Washington County, Maine. The project is expected to boost the local economy and produce clean energy for Maine. Officials voted unanimously in favor of rezoning the project’s site.
Technology From Sticky Mussels, Biomedical Engineer Inspired Again
November 7, 2007 07:47 PM - Paul Schaefer, ENN
Evanston, Ill. - Mussels are well-known for a remarkable ability. They stick to virtually all inorganic and organic surfaces, and they stick with amazing tenacity. And scientists are learning exactly how they do it and modelling new technologies from understanding how the Mussels create stickiness.Northwestern University biomedical engineer Phillip B. Messersmith already developed a material that mimics the strength of the bonds; now he's developed a versatile coating method that mimics the mussels' ability to attach to a wide variety of objects.
Exposing Deadly Diseases in 3-D
November 7, 2007 06:50 PM -
CHICAGO --- With 3-D and some very high tech arrays of technology, scientists are able to 'see' deadly bacteria and viruses in three dimensions, and in all liklihood, come to new understands of how they work, and what will stop their deadly work.
The focus is the proteins of molecular sized killers. Scientists at Northwestern University's Feinberg School of Medicine are mapping parts of lethal bacteria in three dimensions, exposing a new and intimate chemical portrait of biological killers down to their atoms. This view of the disease will offer scientists who design drugs a fresh opening into the bacteria's vulnerabilities, and it's hoped, enable them to create drugs to disable it or vaccines to prevent it.
