theodp writes "PC Magazine's John C. Dvorak has a unique take on the cute One Laptop per Child XO-1, deeming the OLPC project a naive fiasco waiting to unfold that sends an insulting 'let them eat cake' message to the world's poor. When it comes down to a choice of providing African kids living in absolute poverty with access to Slashdot or a $200 truckload of rice, Dvorak votes for the latter. Buy ten OLPCs if it assuages your guilt, says Dvorak, but 'I'll donate my money to hunger relief.'"

Reservoir Hill writes "Zombie insects might sound like a B-movie plot device (quicktime video) but to the emerald cockroach wasp (Ampulex compressa), they're a tried and tested way to provide food for their hungry larvae. The wasp relies on cockroaches for its grisly life cycle but unlike many venomous predators, which paralyze their victims before eating them, the wasp's sting leaves the cockroach able to walk, but unable to initiate its own movement. Researchers have discovered that the wasps sting the cockroaches once to subdue them, then administer another, more precise sting right into their victim's brain. The venom works to block a neurotransmitter called octopamine with a similar action to dopamine, which is involved in preparations to execute complex behaviors such as walking. Then the wasp grabs the cockroach's antenna and leads it back to the nest 'like a dog on a leash', says one researcher. The team found that they could restore spontaneous walking behavior in stung cockroaches by giving them a compound that reactivates octopamine receptors in the insects' central nervous system. Researchers were also able to create their own zombies by injecting unstung cockroaches with a compound that blocks the receptors producing a similar effect to that of the venom."

Roland Piquepaille writes "Researchers at Princeton University are currently working on two projects to reduce jet travel's role in global warming. The first one, a major project funded by the U.S. Air Force with $7.5 million, is focused on developing computational models that accurately simulate the burning of jet fuel, a complex process not well understood today. The second one, funded by NetJets, a company providing business jets, will help to develop new jet fuels with near-zero net greenhouse gas emissions."

The Toronto Star reports researchers have used adult skin stem cells to heal spinal cord injuries in rats. "Injured rats injected with skin-derived stem cells regained mobility and had better walking co-ordination, according to the study published yesterday in the Journal of Neuroscience. The skin-derived stem cells, injected directly into the injured rats' spinal cords, were able to survive in their new location and set off a flurry of activity, helping to heal the cavity in the cord."

NewsCloud writes "Does Facebook believe that no publicity is bad publicity? Why else would they leave a group called, "F**k Islam" open since July 21, 2007 despite more than 53,482 members joining an opposing group called petition: if "f**k Islam" is not shut down..we r quitting facebook group? Furthermore, advertisers such as Sprint, Verizon, T Mobile, Target, and Qwest wouldn't be too happy to learn that they are paying for ads on the 'F**k Islam' group pages. Shouldn't a startup like Facebook, reportedly worth more than a billion dollars and with over a hundred employees, be expected to enforce its own Terms of Use in less than six weeks?"

An anonymous reader writes "You probably already knew that the FBI was data mining Americans in the "search" for potential terrorists, but did you know that they're also supposed to be looking for people in the U.S. engaged in criminal activity that is not really supposed to be the province of the federal government? Now the feds are alleged to be data mining for insurance fraudsters, identity thieves, and questionable online pharmacists. That's what they're telling us now. What else could they be looking for that they are not telling us about?"

Gamespot reports on the final passing of New York senate bill A8696, legislation proposed just last week, that now makes it a serious felony to sell or rent a violent game to minors. The bill makes it illegal to sell a console without parental control options and establishes a group to second guess the ESRB's rating decisions. "'This bill is impermissibly vague,' EMA president Bo Andersen said in a statement. 'A8696 seeks to apply real-world standards of violence to the fictional and fanciful world of video games, an environment in which they have no meaning. As a result, retailers and clerks will not and cannot know with certainty which video games could send them to jail under A8696. It was depressing to hear members of the Assembly note the constitutional problems with the bill and then state that they were voting for it.'" The senate seems to have no fear of possible overturn of the bill, and claims it's only thinking of the children.

hereisnowhy writes "The rising demand for corn as a source of ethanol-blended fuel is largely to blame for increasing food costs around the world, the CBC reports. Increased prices for ethanol have already led to bigger grocery bills for the average American — an increase of $47 US compared to July 2006. In Mexico last year, corn tortillas, a crucial source of calories for 50 million poor people, doubled in price; the increase forced the government to introduce price controls. The move to ethanol-blended fuel is based in part on widespread belief that it produces cleaner emissions than regular gasoline. But a recent Environment Canada study found no statistical difference between the greenhouse gas emissions of regular unleaded fuel and 10 per cent ethanol-blended fuel. Environmental groups have argued that producing ethanol — whether from corn, beets, wheat, or other crops — requires more energy than can be derived from the product."

Jenga717 writes "The US military has launched its own channel on YouTube, in efforts to shift the media's focus of Iraq from a negative to a more positive light, and to 'counter the messages of anti-American sites.' From the article: 'The footage is not picked specifically to show the military in a good light ... and is only edited for reasons of time or content too graphic to be shown on YouTube ... And while all the clips currently posted have been shot by the military's combat cameramen, soldiers and marines have been invited to submit their own clips.' The question is, where are they supposed to submit them? Starting 'on or about 14 May 2007', the Department of Defense will block troop access to Myspace, Youtube, MTV, and more sites, due to a 'growing concern for our unclassified DoD Internet, known as the NIPRNET'."
