His Blue Period

No red, no white, but plenty of blue. That’s the strange ? make that straight-up freaky ? but true story of a sexagenarian Montana Congressional candidate who managed to permanently turn his own skin the color of the sea. The Associated Press reports that back in 1999, Stan Jones, a business consultant and part-time college instructor currently running for U.S. Senate under the Libertarian Party banner, began brewing and drinking a homemade colloidal silver potion. He did this, the wire service notes, because he feared a Y2K-related shortage of antibiotics. He apparently did not anticipate one side effect: his epidermis becoming a primary color….ScienceBlog bonus historical precedent: the famous Blue People of Kentucky.

Research that matters

New Scientist reports on a year-long study to find the world’s funniest joke. The Internet-based project was coordinated by psychologist Richard Wiseman and colleagues at the University of Hertfordshire, U.K. and involved more than 2 million votes on 40,000 submissions. The goal was to identify universal aspects to humor, which could one day allow computers to devise truly funny jokes. Before we get to the winner, an interesting aside is that the team found in the process the world’s funniest animal: the duck. “If you’re going to tell a joke involving an animal, make it a duck,” Wiseman says. Now to the ultimate rib-tickler, which folks from Asia to Africa, the States to Siberia all seemed to enjoy. A couple of New Jersey hunters are out in the woods when one of them falls to the ground. He doesn’t seem to be breathing, his eyes are rolled back in his head. The other guy whips out his cell phone and calls the emergency services. He gasps to the operator: “My friend is dead! What can I do?” The operator, in a calm soothing voice, says: “Just take it easy. I can help. First, let’s make sure he’s dead.” There is a silence, then a shot is heard. The guy’s voice comes back on the line. He says: “OK, now what?” Thank you folks, I’ll be here all week.

Scientists Decipher Genetic Code of Malaria Parasite

FROM THE TRENCHES: A consortium of scientists announced that it has deciphered the genetic code of the parasite that causes the deadliest form of Malaria, an illness that kills more than a million people a year in developing nations.

Facing disfigurement in 2002

With all the discussion about possible smallpox bioterrorism attacks in the U.S., has the dermatology world begun to address the cosmetic implications that an outbreak would entail? Sure, it sounds petty when lives are at stake. But if thousands of people stand to potentially become infected, has medicine developed any better means of preventing disfigurement? Drainage? Lots and lots of aloe gel? Sedatives to keep people doped until the pustules pass?

New worm a real bear

PC users of the world beware! A new worm called BugBear is making the rounds, and New Scientist says it reflects a worrying new trend in virus code. Instead of disabling your computer, or turning it into a denial of service pod to flood other machines with garbage, BugBear contains a Trojan horse program that can collect credit card details, passwords and other private information stored from a computer and send it to a hacker. “When run, the Trojan disables anti-virus programs running on your machine,” New Scientists says. “It then installs a ‘keyboard sniffing’ program that remains in the background and copies every keystroke on your keyboard and saves them to a file. At some point later it opens a network connection and transmits the file to its creator, or bundles it up and sends it out as an email.” One side effect of the worm is that it tries to mail itself to any other machines on your network, including printers. So if you see unexpected, long junk printouts spewing for the LaserJet, you ought to get checked for infection.

Look, up in the sky… CLUNK!

Ice meteors are falling from the sky in growing numbers. And while some skeptics still think the phenomenon a hoax or the result of ice from planes passing overhead, a Spanish scientist says they are neither. Though he doesn’t know precisely how the meteors form, Jesus Martinez-Frias, director of planetary geography at Spain’s Astrobiology Center in Madrid, notes that their results can be dramatic. The falling ice blocks tend to weigh upwards of 20 pounds and have smashed in cars, destroyed roofs and caused general mayhem where they land. But Martinez-Frias says he isn’t concerned so much about the terrestrial damage they can cause, but the atmospheric damage he believes they portend. “I’m not worried that a block of ice might fall on your head … but that great blocks of ice are forming where they shouldn’t exist,” he said. “Components of the atmosphere, like ozone and water, are changing in different levels of the atmosphere. … We think these signs could be evidence of climate change,” he told Reuters.

Two chips, two gambles

The New York Times and the Associated Press take long looks at flip sides of the coming Intel-Advanced Micro Devices war over 64-bit processors. In “Intel’s Huge Bet Turns Iffy,” The Times examines the company’s enormous investment of time and money — 10 years and $5 billion — into the chip, which it co-developed with Hewlett-Packard. The Infineon, or more precisely the Infineon 2 (an earlier version 1 was largely considered a flop) handles enormous quantities of data, but also uses lots of electricity. While the former is nice, the Times says, companies that run big server farms are increasingly mindful about all the juice needed to keep them running and cooled. AMD’s own 64-bit entry, the Hammer, uses less electricity, the Times notes ominously. But as the AP reports, there are no guarantees for AMD either. One of Hammer’s big selling points is that it is backward compatible with current x86 software, meaning anything you’re running now on a Windows box and more. That could make it an appealing crossover product, tempting for use in corporate servers and consumer desktops alike. But with a soft economy and many people happy with the speed they’ve already got, anything short of a groundswell adoption could be a major bummer for the perennial no. 2.

Teeth Grinder’s Lament ? ‘E’ May Wound Brain

Results of an animal study published in the journal Science raise the possibility that the use of the rave fave drug Ecstasy ? methylene-dioxymethamphetamine ? can damage brain cells. The same cells, in fact, that are destroyed by Parkinson?s disease.
“We don’t know if human beings develop the same effects we describe in monkeys and in baboons,” Dr. George Ricaurte, a Johns Hopkins neurologist, told Reuters. “The broader issue is, are there hundreds of cases of unexplained parkinsonism in MDMA users? We don’t know because we haven’t looked.”
The Reuters article also contains the following quotation, reproduced below only marginally out of context: “[A]s you might imagine, it is not easy to get a baboon to take an oral dose of a drug.”

Alien bugs here on Earth?

A tough microbe called Deinococcus radiodurans can withstand blasts of radiation, enduring several thousand times the lethal dose for humans. How did these little bugs develop this resistance? A team of Russian scientists has concluded that these extraordinary organisms are actually Martian microbes, here on Earth by way of meteorites. In tests on common bacteria E. coli, the scientists determined that evolution of radiation-resistance would take longer than 3.8 billion years, the time that life has been on Earth. In contrast, the bugs could develop this characteristic on the Red Planet in only a few hundred thousand years. On Mars there are much higher levels of radiation and the planet experiences regular climate swings that would induce dormancy in microbes, allowing them to accumulate sufficient doses of radiation to evolve into radiation-resistant critters.

Wascally Waksal

Though not strictly a science story, the Wall Street Journal has a devastating profile this morning of Sam Waksal, founder of ImClone. It’s a warning not only for directors of technology-based companies, but for investors and the media, who can be charmed by one person with a winning personality and a compelling story (in this case a promising cancer-fighting molecule). Terrific digging by reporter Geeta Anand reveals a string of research jobs from which Waksal was ousted for misleading and sometimes falsified results. Do yourself a favor and read this one through to the end. Suddenly Martha Stewart’s alleged insider trading of ImClone stock seems like the least of anyone’s worries about Waksal.

From the mouthes of Babe

This weekend I sank my teeth into some delicious beef ribs. But researchers at the Forsyth Institute say they’ve done one better ? they’ve sunk pork teeth into rat guts. The experiment involved taking seeded cells from immature teeth of six-month-old pigs and placing them in the intestines of rats (who no doubt were thrilled at the addition). Within 30 weeks, small tooth crowns made of enamel and dentin had formed. Within five years, the Forsythe team says, they hope to be able to harvest teeth of specific size and shape, and five years after that to regrow human teeth.

From the home office in Lincoln, Nebraska…

Ever woken and wondered, “Is Galileo’s experiment on falling bodies cooler than Millikan’s oil-drop test?” Ponder no more. Physics World has solved the problem, polling its readers on the Top 10 most beautiful experiments in physics. The overall winner? A combined effort: Claus J?nsson’s 1961 application — on the interference of single electrons — of Young’s double-slit experiment.

Device gives smart bombs a headache

Plans for GPS-guided bombs to do much of the heavy lifting in a U.S. war on Iraq could be seriously hampered by a $40 device available over the Internet. As reported by the Wall Street Journal, so-called global positioning system “jammers” can interrupt the system’s satellite signal. “At the Paris Air Show in 1999, a Russian company called Aviaconversia demonstrated a 4-watt GPS jammer, weighing about 19 pounds, capable of denying GPS reception for more than 100 miles,” the paper says. “While we do not know the extent of our vulnerability, there is evidence to suggest that GPS jamming can significantly inhibit precision targeting,” says Rep. Joseph Pitts (R., Penn.), co-chairman of Congress’ Electronic Warfare Working Group. So far the only known fix is to boost the GPS signal strength. But without new satellites in place, there’s only so far that approach can go.
