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.
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.
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.
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.
I don’t know why everyone’s getting excited about this crow being so smart. First, crows are woeful creatures that like as not’ll ruin my corn crop again this year. They trick Pete into giving them access to the tools — flashing fake badges, or telling Pete he’s needed on another part of the farm “pronto.” Then they harvest, bag and truck off the best of the ears. But that makes them smart? A half-bright bunch of third-graders could fool Pete. When a crow tells the president when the big one’s coming, or picks me the right lotto numbers, then, yeah, that’s pretty smart. But for now I’m just laughing. Hell, I can make bent wire tools.
The U.S. government Tuesday morning was monitoring attacks against U.S. Internet providers, hours after European authorities warned the FBI that such an onslaught was likely. A spike of data seven times larger than normal was aimed at East Coast ISPs and Web sites beginning about 2 a.m., the Associated Press reports. The attack then shifted to West Coast facilities. Because the campaign emanated from a relatively small number of computers, the targets were generally able to withstand the barrage by filtering data from the offending machines. Just before the data flood began, the FBI issued an extraordinary warning citing “credible but non-specific information that wide-scale hacker attacks” were planned against U.S. Web sites and Internet providers, the AP said. The European tip-off came from Italian authorities. No word on how they knew it was coming.
Boeing has joined a small group of technology bigwigs trying to test a theory that would let engineers negate some of the effects of gravity. The American aerospace giant is using the work of controversial Russian scientist Yevgeny Podkletnov, who claims to have developed a device that can shield objects from the Earth’s pull. Other researchers claim Podkletnov’s work is hokum, but considering the cost savings such a device would represent for air travel, Boeing seems intent on getting to the bottom of it all. The Russian says he found that objects above a superconducting ceramic disc rotating over powerful electromagnets lost weight, the BBC reports. “The reduction in gravity was small, about 2 percent, but the implications — for example, in terms of cutting the energy needed for a plane to fly — were immense.”
City work crews were busy Friday cleaning up 12 tons of dead and dying squid after what looks to have been the largest mass beaching of the rubbery mollusks in a century. Scientists say the squid were likely following prey, maybe grunion, when they ventured into the shallow waters off La Jolla Cove, California, and were washed up on shore. Locals were freaked. “It was just unbelievable,” Bill Halsey, 26, told Reuters. “They made these strange noises like a dolphin or a seal as they were dying.” Added Clif Williams: “The thing that weirds me out about the squid is that they have humanlike eyeballs.” The jumbo flying squid, aka Dosidicus gigas, usually call the eastern Pacific Ocean home, but have been turning up on beaches from Orange County to the Mexican Border. Researchers think warm water currents associated with El Nino are drawing the suckers north.
A panel of scientists has determined that poison is the best way to rid a Maryland pond of the carnivorous northern snakehead. The fish, a native of China, was introduced into the pond by a pet owner who tired of caring for the animals. Only problem is, the snakeheads are eating everything in sight, devastating the pond’s ecosystem. Worse, the insatiable critters can last three days out of water, often traveling short distances across land on their fins. And the Little Patuxent River is about 75 yards away. According to the Associated Press, “The panel considered several ways to get rid of the snakeheads, including removing them through trapping, netting and electroshock stunning. But those options would not ensure that every last fish was killed. The group also considered draining and filtering the pond, but that posed logistical difficulties.”
