New HIV Strain Discovered 263

reporter and barnyjr were among the readers alerting us to the discovery of a new strain of the HIV virus, found in a woman from the west central African nation of Cameroon. "It differs from the three known strains of human immunodeficiency virus and appears to be closely related to a form of simian virus recently discovered in wild gorillas, researchers report in Monday's edition of the journal Nature Medicine. ... The most likely explanation for the new find is gorilla-to-human transmission, Plantier's team said. But... they cannot rule out the possibility that the new strain started in chimpanzees and moved into gorillas and then humans, or moved directly from chimpanzees to both gorillas and humans. ... Researchers said it could be circulating unnoticed in Cameroon or elsewhere. The virus's rapid replication indicates that it is adapted to human cells, the researchers reported."

A Hypothesis On Segway Hate 487

theodp writes "Admit it, IT is ingenious. Also, IT is surprisingly effective for certain uses, including real cops and mall cops. And if you tried IT, you probably smiled to yourself. So why all the Segway hate? Paul Graham looks into The Trouble with the Segway and offers a hypothesis about what prompts people to shout abuse at Segway riders: 'You look smug. You don't seem to be working hard enough.' Not that someone riding a motorcycle is working any harder, adds Graham, but because he's sitting astride it, he appears to be making an effort. When you're riding a Segway you're just standing there. Make a version that doesn't look so easy for the rider — perhaps resembling skateboards or bicycles — and Segway just might capture more of the market they hoped to reach."

Comment Re:DISA Auditors (Score 1) 211

There are a lot of audits that are never filtered through the stupidity filter before you get pinged. It seems that somewhere around 95% of the IA guys have never done any kind of actual IT work. You end up having to explain every single vulnerability over and over(and they still never get it).

Dye Used In Blue M&Ms Can Lessen Spinal Injury 324

SydShamino writes "Researchers at the University of Rochester Medical Center have found that the dye used in blue M&Ms and other foods can, when given intravenously to a lab rat shortly after a spinal injury, minimize secondary damage caused by the body when it kills off nearby healthy cells. The dye is called BBG or Brilliant Blue G. Given that 85% of spinal injury patients are currently untreated (and some doctors don't trust the treatment given to the other 15%), a relatively safe treatment like this could help preserve some function for thousands of patients. The best part is that in lab rats the subjects given the treatment turn blue." The researchers are "pulling together an application to be lodged with the FDA to stage the first clinical trials of BBG on human patients."

Transparent Aluminum Is "New State of Matter" 406

Professor_Quail writes with this interesting excerpt: "Oxford scientists have created a transparent form of aluminum by bombarding the metal with the world's most powerful soft X-ray laser. 'Transparent aluminum' previously only existed in science fiction, featuring in the movie Star Trek IV, but the real material is an exotic new state of matter with implications for planetary science and nuclear fusion."

Healing Wounds With Diamonds 109

A team at Northwestern University, led by Dean Ho, has discovered that nanodiamonds are a wound's best friend. Insulin is very attracted to nanodiamonds and in addition to regulating blood sugar, insulin can accelerate the healing process and stave off infection in wound sites. Since the tiny diamond can be easily placed in a wound without causing further damage, this is an excellent way to get an increased amount of insulin there as well. From the article, "A substantial amount of insulin can be loaded onto the nanodiamonds, which have a high surface area. The nanodiamond-insulin clusters, by releasing insulin in alkaline wound areas, could accelerate the healing process and decrease the incidence of infection. Ho says this ability to release therapeutics from the nanodiamonds on demand represents an exciting strategy towards enhancing the specificity of wound treatment."

Finally, a True Green Laser 274

dusty writes "Remember those green lasers from Star Wars? Turns out that faking green lasers has been easy for years, but making true green laser diodes has been the stuff of science fiction. Until recently, that is. Now researchers from Japan have created the world's first true green laser diode. Until now, only red and blue laser diodes were available, and now with the addition of green, new TVs and projectors that are more efficient can be produced. And if you were wondering how green lasers pointers are already produced, it is a hack that involved doubling the frequency of an infrared laser. The new true green laser diodes have much higher efficiency than the current 6%, leading many to expect big time laser display breakthroughs in the near future. Ars Technica has a well-written article on this breakthrough."

Formerly Classified Global Warming Spy Photos Released 791

An anonymous reader writes "The Obama administration has released more than a thousand intelligence images of Arctic ice, following a declassification request by the National Academy of Sciences. The images feature a 1m resolution, and scientists who have had to base climate models on 15m- or 30m-resolution photos are rejoicing. The photos, kept classified by the Bush administration, show the impact of global warming in the Arctic and the retreat of glaciers in Washington and Alaska."

English DJ Claims Wi-Fi Allergy 515

path0$ writes "British Ex-DJ Steve Miller claims that his Wi-Fi allergy is making his life one big misery , forcing him to live in an iron-clad home far from any neighbors. According to the article, more and more people are suffering from an allergy like his. The only positive side to this is that at least Miller didn't think of suing anybody yet, like these people did, who claim to suffer from the same condition and were mentioned in a Slashdot article in 2008."

Wireless Power Demonstrated 124

Necroloth and other readers sent in the story of Witricity's latest demo at the TED Global conference in Oxford, UK. The company is developing a system that can deliver power to devices without the need for wires. The idea is not new — electrical pioneers Thomas Edison and Nicola Tesla assumed that power would be delivered wirelessly. The BBC quotes the inventor behind Witricity's tech as saying that Tesla and Edison "...couldn't imagine dragging this vast infrastructure of metallic wires across every continent." eWeek Europe notes some hurdles the technology must overcome: "The 2007 experiment it is based on had an efficiency of only around 45 percent, but [Witricity's CEO] promised power delivered wirelessly would start out 15 percent more expensive than wires, and improve on that." Intel has also demonstrated wireless charging.

First New Nuclear Reactor In a Decade On Track 575

dusty writes "Plans to bring online the first new US nuclear plant since 1995 are on track, on time, and on budget according to the Tennessee Valley Authority. TVA had one major accident with a coal ash spill of late, and one minor one. The agency has plans and workers in place to have Unit 2 at Watts Bar, near Knoxville, online by 2012. Currently over 1,800 workers are doing construction at the plant. Watts Bar #1 is the only new nuclear reactor added to the grid in the last 25 years. From the article: 'TVA estimates the Watts Bar Unit 2 reactor every year will avoid the emission of about 60 million metric tons of greenhouse emissions linked with global warming. ... TVA began construction of Watts Bar in 1973, but work was suspended in 1988 when TVA's growth in power sales declined. After mothballing the unit for 19 years, TVA's board decided in 2007 to finish the reactor because it is projected to provide cheaper, no carbon-emitting power compared with the existing coal plants or purchased power it may help replace.'"
