Japanese Beetle May Help Fight Hemlock-killing Insect

The eastern hemlock, a tall, long-lived coniferous tree that shelters river and stream-side ecosystems throughout the eastern United States and Canada, is in serious danger of extinction because a tiny, non-native insect is literally sucking the life out of it. Entomologists are now studying a beetle from Japan that may be a natural predator.

Surprise Strategy: Bees Smother Enemies (LiveScience.com)

LiveScience.com - Cyprian honeybees don't smother their enemies with kindness—they just smother them to death, research now reveals. This novel strategy has never been seen before in insects, "and probably in all animal species," apidologist Gerard Arnold at the National Center of Scientific Research in France, told LiveScience. Cyprian honeybees (Apis mellifera cypria)...

Chipmakers Looking Beyond Silicon

We're used to computers becoming obsolete almost as soon as they leave the store because of rapid advances in chip technology, but the whole science of silicon chips is starting to show its age. Industry leaders say it must be retired within 10 years and replaced with something better, if computer technology is to continue advancing at the current pace. It's not clear what that new...

Genes That Improve Survival In Mice With ALS Identified

Researchers investigating the basic biology of cell signaling have made a discovery that may have therapeutic implications for amyotrophic lateral sclerosis (Lou Gehrig's disease) and other neurodegenerative diseases. They discovered that two cell-signaling proteins called Nox1 and Nox2 appear to play an important role in disease progression of an inherited form of ALS.

Missing Link In The Evolution Of Magnetic Cataclysmic Stars?

Astronomers might have discovered the missing link in the evolution of the so-called magnetic cataclysmic variable stars. They determined the spin and orbital periods of the binary star Paloma. They found that the Paloma system has a weird way of rotating that fills the gap between two classes of magnetic cataclysmic stars.

Nanotubes And Nano-rods Show Promise As Catalysts, Sunscreen

Scientists have developed new ways to make or modify nanorods and nanotubes of titanium oxide, a material used in a variety of industrial and medical applications. The methods and new titanium oxide materials may lead to improved catalysts for hydrogen production, more efficient solar cells, and more protective sunscreens.

Salmon DNA Points The Way To Green Electronics

An expert in light-emitting diodes is intensifying the properties of LEDs by introducing biological materials, specifically salmon DNA. Electrons move constantly — think of tiny particles with a negative charge and attention deficit disorder. It is through the movement of these electrons that electric current flows and light is created. He believes that if the electrons’ mobility could...

Microsoft Loses Antitrust Appeal in Europe

The European Union's Court of First Instance has rejected Microsoft's appeal of the European Commission's 2004 landmark antitrust decision against the company, which concluded that the software giant had abused its dominant position in the computer industry "by leveraging its near monopoly in the market for PC operating systems."

Microsoft Must Share Code with Rivals

Microsoft lost its appeal of a European antitrust order Monday that obliges the technology giant to share communications code with rivals, sell a copy of Windows without Media Player and pay a $613 million fine -- the largest ever by EU regulators. The EU Court of First Instance ruled against Microsoft on both parts of the case, saying the European Commission was correct in concluding that...

NASA Revamps Shuttle Repair Plans

NASA hopes to test a thermal tile patch on the next space shuttle mission that could have been used to fix the gouge that was carved into the bottom of Endeavour during last month's launch. The repair -- a squirt of goo -- was one of three methods NASA considered using before deciding the damaged tiles didn't need to be fixed in flight. Shuttle program manager Wayne Hale said Friday he...

China Recalls Tainted Leukemia Drugs

Chinese authorities ordered the recall of tainted leukemia drugs blamed for leg pains and other problems, state media reported Sunday, the latest crisis to strike the country's embattled food and drug industries. Most of the drugs involved -- methotrexate and cytarabin hydrochloride -- have been recovered and authorities have traced the remainder, the Xinhua News Agency said. The report did...

The committee that oversees the California Institute of Regenerative Medicine voted Friday at a meeting in Los Angeles to appoint Alan Trounsoun the institute's new president. "Alan is a world-class scientist," said Dr. George...

Doctor Details 9/11 Workers' Illnesses

Doctors treating sickened ground zero workers offered Congress a detailed diagnosis Wednesday of the ailments still affecting thousands after the Sept. 11 attacks, but warned that there's no way to determine how many more may become afflicted with life-threatening illnesses. Dr. Philip Landrigan of the Mount Sinai School of Medicine described three months of recent medical treatment to a...

Arctic Ice Retreating to Record Lows

Arctic ice has shrunk to the lowest level on record, new satellite images show, raising the possibility that the Northwest Passage that eluded famous explorers will become an open shipping lane. The European Space Agency said nearly 200 satellite photos taken this month showed an ice-free passage along northern Canada, Alaska and Greenland, and ice retreating to its lowest level since such...
