PCs aren’t known for being great friends of the environment. Chip making uses toxic chemicals, wastes water, and pollutes both water and air. Computers and components fill up landfills and add heavy doses of lead to the solid waste stream. NEC Solutions America says it’s taking a step toward a more environmentally friendly computer with the PowerMate eco — the first all-in-one, fanless ecological PC. The PowerMate eco has a 15-inch flat panel screen that contain none of the boron found in traditional CRT monitors and radiates less heat than its tubular counterparts; its motherboard is made with lead-free solder; it uses laptop components and has a “boxless” design; it has no fan; and it is made of a 100 percent recyclable plastic. The desktop is targeted at high density computing locations where noise, heat and desktop real estate are big concerns — like call centers, hospitals, reception desks and financial trading rooms.
Apple in recent years has sought to close the megahertz gap with Intel and Advanced Micro Devices by selling high-end machines that come with two processors instead of one. Thus, a dual-processor 1.2GHz G4 can reasonably claim to compete with a 2.5GHz Intel box. But Intel reckons there’s more than one way to build a two-brained beast and is experimenting with putting two processor cores on a single piece of silicon. It’s a process that CNET’s News.com says over the next decade will improve performance and reduce power consumption. One advantage is the ability to better dissipate heat. When a series of calculations has Core A chugging along at full steam, its transistors can hit temperatures that start to degrade performance. When that happens, the chip can “hop” some of the work over to Core B for an overall performance improvement. Another approach is to have Core A and Core B specialize in different things, similarly spreading the number-crunching responsibility around.
This is something that’s been talked about for years, though before Sept. 11 it was always in the context of a bank or high-security government facility, not Northwest Airlines. The upshot of this Washington Times article is that NASA and Northwest are teaming to see if mind-reading technology is feasible, and if so, can it be used to mass-screen airline passengers. Opinion is mixed, and no one in this article addresses the pharmaceutical countermeasures that could potentially be employed to calm a guilt- or panic-ridden brain and heart. Still, plenty creepy.
Despite financial setbacks that threatened to keep boyish pop star Lance Bass from his life-long dream of traveling to outer space, Bass continues to train to join a Russian crew heading to the International Space Station in October. The cost of sending Bass into space is said to be about $20 million, and the mission, which Bass has been training for since July, became jeopardized when payments were not made on time. If he makes it there, the 23-year-old Bass would be the youngest person to travel to outer space.
Live near the ocean? Ever wonder why your air is so clean, while the poor saps inland keep dying from smog? Reuters reports salty sea spray actually scrubs out air pollution. According to an article published in the journal Science, some of the spray rises high into the atmosphere and helps create raindrops, which drag pollution back down to earth (they also make you wet when it rains.) “The idea that larger salt particles can seed clouds and enhance rainfall is not new but it was not combined with actual observation,” says Daniel Rosenfeld, who conducted the experiment.
It has been a big week for the common lab mouse. Tests in mice showed that the deadly botulism toxin could be neutralized with an experimental drug. The drug, fashioned from two antibodies from mice and one from a human, could be mass-produced and thus could be used as a deterrent to the use of botulism toxin as a weapon. In other mouse news, scientists at the Universiy of Pennsylania have figured out that they can turn mice into goat and pig sperm “factories” by grafting testes onto their backs. The technique could be used in the future to make sperm for young cancer patients left infertile after treatment, to help human couples struggling with male fertility problems, and to preserve species close to extinction. The most amazing mouse news of the week? Researchers at the Dana-Farber Cancer Institute in Boston created a transgenic mouse with Lance Armstrong-like capabilities, able to endure hard exercise for extended periods of time.
Following devastating floods that submerged central Prague in water and caused 200,000 Czechs to leave their homes, the Czech government said it will be vaccinating 65,000 children against hepatitis A — a liver disease that can spread when sewage systems are damaged and infected feces enters the drinking water. The Czech Republic’s health minister has also asked the government to provide 3.5 million euros for other public health measures. The flooding has killed more than 100 people across Europe and caused billions of euros’ worth of damage. It’s not just the people who are hurting — in the Czech Republic 100 animals died during the evacuation of Prague Zoo.
Remember Segways, those nifty electric scooters that resemble “lawn mowers on steroids”? The San Jose Mercury News reports that a key piece of legislation that would allow them on California sidewalks faces a showdown today in the state’s assembly. And the outcome could make or break the transporter’s future in the nation’s most populace state. Who opposes the proposed five-year experiment? Advocates for senior citizens, the disabled and pedestrians, who say the bill would turn California sidewalks into raceways. In support? Segway, naturally. Silicon Valley venture capitalist John Doerr. And geeks from San Diego to Yuba City.
New Scientist says that a military attack on Iraq could see the first use of an e-bomb designed to destroy electronics but not harm people. U.S. intelligence reports that Iraq has moved much of its military infrastructure underground or beneath civilian buildings like hospitals. As such, the magazine says, the role of non-lethal and precision weapons would be a critical factor in any conflict. The U.S. reportedly has in its arsenal High Power Microwave (HPM) devices that produce an electromagnetic field so strong they can destroy electronic equipment in hardened command, control, communications and computer targets. One mechanism for achieving this sounds like something out of “Back to the Future”: An explosive pumped flux generator. That device is essentially a bomb which with a combination of explosives and electronics, sends out an electromagnetic wave of up to tens of millions of Amps. By comparison, a typical lightning strike — which can wreak plenty of damage on its own — carries just 30,000 Amps.
