No ‘Fear Factor’ for Thai goverment

Government officials in Thailand have been whining about the new trend of adopting giant African roaches as pets. Because they make lousy pets? No. Because they’re supposedly filthy. The people of Bangkok — like children in classrooms and museums the world over — are quite taken with the large Madagascar hissing cockroach, and are snapping them up at the popular Chatuchak market. But the goverment is worried that escaped roaches could become a health risk and is asking vendors to stop selling them. The Madagascar hissing cockroach is a docile, slow-paced creature that can grow to 3 inches and live for more than 3 years; its name derives from the fact that it can force air through a pair of breathing pores in its abdomen to make a hissing noise. It has not been established that roaches actually do spread disease, though some people are allergic to the feces of certain species. The hissing roach lives outdoors in the jungles of Madagascar with the lemurs and chameleons, and like 99 percent of roach species is not a household pest. (And check out the roach cam.)

When to pull the cyber trigger

The Washington Post, which built its reputation covering the federal government, has in the last year or two carved out a respectable niche in the tech sector. The two come together in stories like this, in which reporters Ariana Eunjung Cha and Jonathan Krim delve into the debate underway in the Bush administration on the proper rules of engagement for cyberwarfare. Bush’s point man on the topic, Richard Clarke, says it’s still nation-states that pose the biggest threat in the cyber arena, not terrorist groups. The administration has traced break-ins back to foreign governments and even reckons a state may have been involved in developing last year’s damaging Code Red virus. The prospect of more attacks has led the government to explore how far it is willing to go to counter such incidents. The Geneva Convention prohibits attacks on civilians, and given the interconnectedness of computers around the world, any campaign against an enemy military network could seep into computers at large — and even back to the U.S. itself. It’s a fun, thought-provoking read. So go read it.

Long-life contact lenses

A Texas scientist has discovered that a special metal coating could allow contact lens wearers to keep their lenses in for longer periods of time. Coating contacts with a one-molecule-thick layer of selenium, an antibacterial metal, keeps them bacteria-free for at least two months, says Ted Reid of Texas Tech University Health Sciences Center in Lubbock. Although selenium can be toxic to humans in large quantities, these lenses would apparently be safe, with less selenium than you’d find in an average lunch. Reid hopes the coating could be used on other internal devices, like heart valves and catheters, and even suggests selenium-coated molecules could be used to keep people exposed to HIV from becoming infected. In other eye news, new eye-tracking software developed by scientists at Cambridge University could help computer users with disabilities write more quickly, accurately, and comfortably than before.

A lean green computing machine

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.

Intel’s latest: Two brains, one chip

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.

NASA, Northwest team on mind-reading tech

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.

Space is the place … for Bass

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.

Salt of the Earth

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.

Mice in the news

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.

Czechs to get vaccinated after flooding

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.

All aboard! Segway faces key test

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.

U.S. got its e-bomb on

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.

Avoid skeeter bites, says CDC

In response to outbreaks of West Nile virus throughout the eastern U.S., the Centers for Disease Control and Prevention has pointed out that the best way to avoid infection is to avoid mosquito bites. West Nile virus is spread by the bite of an infected mosquito, and in addition to humans can infect horses, many species of birds, and some other animals. Fortunately, most people who become infected with West Nile virus will have either no symptoms or mild ones. But on rare occasions, infection can result in West Nile encephalitis, a severe and sometimes fatal inflammation of the brain. (The risk of severe infection is higher for persons 50 years of age and older.) Officials in Washington D.C. have been getting the word out about protective measures people can take after West Nile virus infected a 55-year-old resident, who is now hospitalized with encephalitis. As of Thursday, state health departments around the U.S. have released information on 113 cases of human illness related to West Nile virus this year, including 5 deaths.
