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.
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.
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.
IBM Wednesday opened a sophisticated semiconductor plant in East Fishkill, NY. The $2.5 billion facility is the single biggest capital investment the company has ever made, and presumably reflects an optimism that things will improve for the tech sector generally, and the beleaguered chip business in particular.
The new factory will make processors for everything from videogames and cell phone to mainframe computers. “The plant also will be the first to mass produce circuits thinner than 0.1 micron, or 1,000 times thinner than a human hair,” the Associated Press reports. “The old standard was 0.25 microns, with some chips now at 0.18 microns. The thinner lines, or conduits, allow chips to run faster and use less electricity.”
When it begins normal production next year, the factory is expected to employ about 1,000 East Fishkillers.
FCC Chairman Michael Powell sent a good strong scare into lawmakers Tuesday when he testified that WorldCom might be able to shut down its UUNET subsidiary’s Internet backbone without government approval. UUNET is a major component on the Internet, and its loss could potentially have devastating effects, particularly on corporate and government clients.
“Mr. Powell said he was confident in the long-term health of the telecom industry,” the Wall Street Journal reports. “But in the short term, ‘there are question marks’ about whether the FCC can order a bankrupt company’s Internet subsidiary to keep its backbone operational. ‘I could hypothesize that (the company) would refuse to comply.'”
After Powell’s shake-em-up, Senate Commerce Committee Chairman Ernest Hollings, a South Carolina Democrat, said he would introduce legislation to clarify the agency’s authority over Internet-backbone companies like UUNET. The Journal notes that the panel reacted positively to Powell’s request for Congress to strengthen the FCC’s jurisdiction over telecom companies that file for bankruptcy protection, to ensure it can stop them from shutting down essential services.
The genome of the pufferfish, a Japanese delicacy, is teaching researchers about the more complex genetic makeup of humans. The pufferfish, or Fugu, has about the same number of genes as humans, but without most of the repetitive “junk” DNA found in naked apes, researchers at the Joint Genome Institute in Walnut Creek, California, report. Fugu can pack a lethal tetrodotoxin whallop, but manages to do so with the smallest genome of any vertebrate. The findings were detailed in the journal Science and reported on by the Associated Press.
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.
Stargazers this week may be surprised by the sight of a glowing orange object streaking across the night sky. It?s the International Space Station, which is making bright passes over the U.S. and Canada until mid-August. The ISS — which travels at 17,000 mph and circles the planet 16 times a day — crosses the sky in three to six minutes, and can shine more brightly than any planet or star except our sun and moon. (Its brightness depends on its orientation, your location and the sun.) Right now this impressive sight can be observed by the unaided eye if skies are clear. (A flyby near downtown Los Angeles on Wednesday night was clearly visible despite city lights.) To find out when the station will fly above your town, orbit over to NASA SkyWatch.
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.”
A single gene change that boosts the amount of a certain protein in early brain cells causes mice to develop abnormally large brains, Reuters Health reports. Normal mice have smooth, flat brains. But tinker with the gene in question and suddenly the little furballs develop brains so big they fold in on themselves, forming the wrinkles, ridges and crevices found also in the human brain. Study author Dr. Anjen Chenn of Brigham and Women’s Hospital and Harvard University in Boston said the finding might help researchers understand how humans came to develop brains so much bigger than those of other mammals. Whether or not more size means more smarts is uncertain, Chenn said. “It is quite an interesting question … and that’s something we want to look at in the future.”
