There hasn't been another major radioactive leak, but soon we could see flesh wounds glowing in the dark. Researchers at the University of Sheffield in the U.K. have developed a gel that glows under ultraviolet light when it comes in contact with many kinds of bacteria.

The gel also appears to be effective in fighting the bacteria at the same time.

"The polymers (in the gel) incorporate a fluorescent dye and are engineered to recognize and attach to bacteria, collapsing around them as they do so," Sheffield Professor Sheila MacNeil explains in a statement. "This change in polymer shape generates a fluorescent signal that we've been able to detect using a handheld UV lamp."

Project lead Dr. Steve Rimmer adds that the technology could help reduce the overuse of antibiotics. In testing, the gel has been able to detect the presence of serious bacterias including Salmonella, E. Coli, MRSA, and meningitis.… Read more

Earlier this year, researchers at the European Molecular Biology Laboratory in Heidelberg, Germany, published a study identifying genetic markers found in people's stomachs that appear related to obesity and other diseases.

After that, "I got between 50 and 100 e-mails from regular people having problems with the stomach or diarrhea and wondering if we can help them," Peer Bork, a biochemist at the lab, told Nature last week. "They were long e-mails. There must be a lot of frustrated people out there."

Given the interest level, Bork and his colleagues launched MyMicrobes, which could be … Read more

Germaphobes may want to navigate away from this page, lest they find themselves tempted to scrub their cell phones as often as their hands. Because cell phones are not only dirty, some of them even play host to what researchers are calling "worrisome" drug-resistant bacteria.

A team from the Department of Medical Microbiology at Inonu University in Malatya, Turkey, set out to answer the question that serves as the title of their report: Do mobile phones of patients, companions, and visitors carry multidrug-resistant hospital pathogens?

They cultured 200 mobile phones, collecting swab samples from three parts of each … Read more

Chemists at Bar-Ilan University in Israel say they have developed and successfully tested "killer paper" coated with silver nanoparticles--each roughly 1/50,000 the width of a human hair--that can fight bacteria such as E. coli and S. aureus.

Described in the American Chemical Society journal Langmuir, researcher Aharon Gedanken tells me that while colloidal silver is already widely used as an antimicrobial agent, what's new about his team's research is the process by which silver nanoparticles are deposited onto paper to develop antimicrobial properties.

The team was able to control both the thickness of the … Read more

The next time you get injured, go ahead and swear.

Researchers who found that cursing actually relieves pain were among the winners of Ig Nobel prizes today. Also honored were projects on whale snot and certain things fruit bats do while copulating.

Sponsored by the science humor magazine "Annals of Improbable Research," the annual awards were presented tonight in a ceremony at Harvard University to projects that "cannot and should not be reproduced."

The Ig Nobel peace prize was awarded to research from Keele University in the U.K. that confirmed that swearing can lessen pain. … Read more

Fans of old Chinese martial-arts dramas will have heard of the saying "use poison to combat poison." I've always considered that to be ridiculous, but it turns out the idea is ahead of its time, as now you can purify water using bacteria.

Forget what you know about bacteria and germs. Bacteria is not evil, it's just another simple organism trying to survive and propagate. Researchers at Sam Houston State University in Texas have successfully designed a portable water purification system that uses a set of common bacterial strains to create potable water in less than … Read more

Samsung has announced a 10-inch Netbook which, among other things, kills bacteria. The N310 has been styled by award-winning Japanese designmeister Naoto Fukasawa and will presumably be welcomed with open--but latex-gloved--arms by OCD sufferers.

It boasts a frameless 10-inch screen and pebble design keyboard, which Samsung reckons is 93 percent of the size of a desktop keyboard for easy typing.

The N310 weighs about 2.6 pounds with a four-cell battery, which Samsung claims will give you up to five hours without busting out some mains supply. Battery savings come from the LED display and optimized performance from the Intel … Read more

Scientists from four Indian universities announced a discovery that enables them to use bacteria enzymes to trap and sequester CO2.

Researches found a way to use seven bacteria enzymes to speed up chemical reactions that convert carbon dioxide to calcium carbonate, according to a Cleantech Group article. Calcium carbonate is typically found in limestone or chalk and can be used in cement to built roads.

While it's not clear if this breakthrough could be used to help capture carbon emitted by existing cars on the road, it may have an application to improve the environmental impact of electric cars. … Read more

Libe Goad joins the guys of the 404 to talk about how the Wii gets hacked, GTA IV gets a lot of cash, get in shape with Wii Fit, Boom some Blox and some silly-ass stop signs. We also make fun of her husband, but shh...don't tell him.
