GreenDisk: a viable e-waste solution?
April 1, 2008 09:11 AM - , Triple Pundit

Computers are becoming cheaper and easier to manufacture by the minute. Intel's new Atom processor is bound to create a whole new set of net-enabled devices at extremely low cost. While the processor is not out yet and prices are not set in stone, rumors price new "net-top" computers below $200. Cheaper computers make electronic recycling all the more relevant. Computers and gadgets are being replaced more frequently as electronics become obsolete in a matter of months.

Study sheds light on Woolly Mammoth demise
April 1, 2008 12:12 AM - Reuters

LONDON (Reuters) - Climate change drove woolly mammoths to the edge of extinction and then humans finished them off, according to a Spanish study on Tuesday that adds to the debate over the demise of the Ice Age behemoths. Using climate models and fossil remains, the researchers determined that warming temperatures had so shrunk the mammoths' habitat that when humans entered their territory about 6,000 years ago the species were already hanging by a thread.

What's keeping us from Mars? Space rays, say experts
March 31, 2008 07:35 PM - Reuters

WASHINGTON (Reuters) - Cosmic rays are so dangerous and so poorly understood that people are unlikely to get to Mars or even back to the moon until better ways are found to protect astronauts, experts said on Monday. And NASA is not properly funding the right experiments to find out how, the National Research Council committee said.

BMW Hydrogen 7 Emissions Well-below Super-ultra Low-emission Vehicle Standards
March 31, 2008 10:03 AM - DOE/Argonne National Laboratory.

Independent tests conducted by engineers at the U.S. Department of Energy's (DOE) Argonne National Laboratory on a BMW Hydrogen 7 Mono-Fuel demonstration vehicle have found that the car's hydrogen-powered engine surpasses the super-ultra low-emission vehicle (SULEV) level, the most stringent emissions performance standard to date.

Particle smasher 'not a threat to the Earth'
March 31, 2008 09:43 AM - New Scientist

Campaigners in the US are attempting to delay the start-up of the world's most powerful particle smasher with a lawsuit claiming it could spawn dangerous particles or mini black holes that will destroy the entire Earth. The Large Hadron Collider (LHC) is nearing completion at CERN, the European centre for particle physics near Geneva, Switzerland. Scientists hope it will begin operations in mid-July.

Man-made molecules reverse liver cirrhosis in rats
March 31, 2008 08:20 AM - Reuters

HONG KONG (Reuters) - Scientists in Japan have designed artificial molecules that when used with rats successfully reversed liver cirrhosis, a serious chronic disease in humans that until now can only be cured by transplants. Cirrhosis is the hardening or scarring of the liver, and is caused by factors such as heavy drinking and Hepatitis B and C. The disease is especially serious in parts of Asia, including China.

Virtual Snow-World Helps Patients Feel no Pain
March 28, 2008 11:45 PM - ,

For most of us, the blustery, teeth-chattering months of winter are just about over, and we've got to say, we're pretty happy about that. While ice skating from your house to your mailbox can be fun once or twice, it tends to lose its charm after one too many slips and bruises. But even though the sun may finally be shining, you can enter your own winter wonderland any time you like: Just slip on a pair of virtual-reality goggles to step into a land filled with icicles, flurries of snow, and maybe even an errant penguin or polar bear.

Despite EASSy, Africa Still Listening to Radio
March 28, 2008 11:02 PM - , Global Policy Innovations Program

Construction began this month on the East African Submarine Cable System (EASSy), which promises to bring low-cost, high-speed Internet access to eight countries. Funded by telecommunications operators and development institutions, the project is scheduled for completion in late 2009 and expected to create and enhance connectivity for millions of people. Internet penetration rates are in the single digits in most of Africa, and countries on the east coast rely on slow and expensive satellite connections.

Scientists find that squid beak is both hard and soft, a material that engineers want to copy
March 28, 2008 09:16 AM - University of California - Santa Barbara

(Santa Barbara, Calif.) –– How did nature make the squid’s beak super hard and sharp –– allowing it, without harm to its soft body –– to capture its prey? The question has captivated those interested in creating new materials that mimic biological materials. The results are published in this week’s issue of the journal Science.

The end of the silicon chip : carbon nanotubes
March 28, 2008 09:02 AM - Institute of Physics

The future of computing is under the spotlight at the Institute of Physics’ Condensed Matter and Materials Physics conference at the Royal Holloway College of the University of London on 26-28 March.The end of the silicon chip The silicon chip, which has supplied several decades’ worth of remarkable increases in computing power and speed, looks unlikely to be capable of sustaining this pace for more than another decade – in fact, in a plenary talk at the conference, Suman Datta of Pennsylvania State University, USA, gives the conventional silicon chip no longer than four years left to run.
