Marijuana Could Prevent Alzheimer's, New Study 807

Chickan writes "'A puff a day might keep Alzheimer's away, according to marijuana research by professor Gary Wenk and associate professor Yannic Marchalant of the Ohio State Department of Psychology. Wenk's studies show that a low dosage in the morning of a certain canavanoid, a component in marijuana, reversed memory loss in older rats' brains. In his study, an experimental group of old rats received a dosage, and a control group of rats did not. The old rats that received the drugs performed better on memory tests, and the drug slowed and prevented brain cell death.' My fine university's dollars at work!" Maybe it works even better in combination with brain-preserving sips of coffee.

Mars Rover Spirit Still Alive 185

Toren Altair writes with this excerpt from a story at The Space Fellowship: "NASA's Mars Exploration Rover Spirit communicated via the Mars Odyssey orbiter today right at the time when ground controllers had told it to, prompting shouts of 'She's talking!' among the rover team at NASA's Jet Propulsion Laboratory, Pasadena, Calif. 'This means Spirit has not gone into a fault condition and is still being controlled by sequences we send from the ground,' said John Callas of NASA's Jet Propulsion Laboratory, Pasadena, Calif., project manager for Spirit and its twin, Opportunity."

Ballmer "Interested" In Open Source Browser Engine 410

Da Massive writes "'Why is IE still relevant and why is it worth spending money on rendering engines when there are open source ones available that can respond to changes in Web standards faster?,' asked a young developer to Microsoft CEO Steve Ballmer in Sydney yesterday. 'That's cheeky, but a good question, but cheeky,' Ballmer said. Then came the startling revelation that Microsoft may also adopt an open source browser engine. 'Open source is interesting,' he said. 'Apple has embraced Webkit and we may look at that, but we will continue to build extensions for IE 8.'"

Discuss the US Presidential Election 1912

We made it. It's election day. Tomorrow we'll know. So for today's election discussion story, I'm throwing it wide open: let's discuss the election itself. Who are your picks and why. And also what about your actual experience voting today? Did Diebold eat your vote or did everything go off without flaw?

Nasa Details Shuttle's Retirement 400

schliz writes "Nasa has announced that it intends to officially retire the aging space shuttle fleet by 2010, four years before it has a replacement craft ready. The space shuttle fleet will make ten more flights, mainly to add modules to the International Space Station and carry out repairs and upgrades to the Hubble orbital telescope. The retirement will leave the US without orbital capacity for at least four years, until the Ares booster programme is complete. European and Russian launchers will service the space station in the meantime."

Lost the Remote? Use Your Face 88

coondoggie writes "A researcher has discovered a way to use facial expressions to speed and slow video playback. By using a combination of facial expression recognition software and automated tutoring technology Jacob Whitehill, a computer science Ph.D. student from UC San Diego's Jacobs School of Engineering, is leading the project that ultimately is part of a larger venture to use automated facial expression recognition to make robots more effective teachers. The researchers recently conducted a pilot test with 8 people that demonstrated information within the facial expressions people make while watching recorded video lectures can be used to predict a person's preferred viewing speed of the video and how difficult a person perceives the lecture at each moment in time."
It's funny.  Laugh.

I Will Derive 269

Jamie stumbled upon a very choice video this morning called I Will Derive. To the tune of some song you've never heard before, singing about subjects you know nothing about... oh and a a TI-84 cameo. It features the dopiest dancing you'll see on YouTube today. I promise.

20% of U.S. Population Has Never Used Email 279

Ezratrumpet writes "A recent PC World article notes that 20 percent of the U.S. population has never sent an email. Does this number over- or underestimate the actual number of people who know nothing of email? What are the implications of this statistic to our society? Or are these people just Luddites who mourned the demise of the telegraph and have also never used a telephone?"

Submission + - Giant Sheets Of Dark Matter Detected (discovery.com) 2

Wandering Wombat writes: "The largest structures in the universe have been, if not directly found, then at least detected and pounced upon by scientists. FTA:


The most colossal structures in the universe have been detected by astronomers who tuned into how the structures subtly bend galactic light. The newfound filaments and sheets of dark matter form a gigantic features stretching across more than 270 million light-years of space — three times larger than any other known structure and 2,000 times the size of our own galaxy. Because the dark matter, by definition, is invisible to telescopes, the only way to detect it on such grand scales is by surveying huge numbers of distant galaxies and working out how their images, as seen from telescopes, are being weakly tweaked and distorted by any dark matter structures in intervening space.

By figuring how to spot the GIGANTIC masses of dark matter, hopefully we can get a better understanding of it and find smaller and smaller structures."

Hi, I Want To Meet (17.6% of) You! 372

Frequent Slashdot contributor Bennett Haselton wants to make online dating better. Here's how he wants to do it. "Suppose you're an entrepreneur who wants to break into the online personals business, but you face impossible odds because everybody wants to go where everybody else already is (basically, either Match.com or Yahoo Personals). Here is a suggestion that would give you an edge. In a nutshell: Each member lists the criteria for people that they are looking for. Then when people contact them, they choose whether or not to respond. After the system has been keeping track of who contacts you and who you respond to, the site lists your profile in other people's search results along with your criteria-specific response rate: "Lisa has responded to 56% of people who contacted her who meet her criteria." Read on for the rest of his thoughts.

World's Most Powerful Rail Gun Delivered to US Navy 615

An anonymous reader writes "The world's most powerful functional rail gun capable of accelerating projectiles up to Mach 8 has been delivered to the Navy. The new rail gun is a 32-megajoule Electro-Magnetic Laboratory Rail Gun. The Navy eventually hopes to have 64-megajoule ship mounted rail guns. 'The lab version doesn't look particularly menacing -- more like a long, belt-fed airport screening device than like a futuristic cannon -- but the system will fire rounds at up to Mach 8, drawing on tremendous amounts of electricity to generate the current for each test shot. That, of course, is the problem with rail guns: Like lasers, they're out of step with modern-day generators and capacitors. Eight and 9-megajoule rail guns have been fired before, but providing 3 million amps of power per shot has been a limitation.'"

Submission + - Has the Higgs boson been hiding in plain sight? (sciencemag.org)

sciencehabit writes: From Science: "Thousands of particle physicists are spending billions to try to spot the elusive Higgs boson, which is key to explaining the origins of mass. But evidence of the Higgs boson — or at least a Higgs boson — may already be lying unnoticed in data from previous experiments..."
