Drugs Eradicate the Need For Sleep 772

MattSparkes writes "New Scientist is running an article on lifestyle drugs that claim to help you function on little or no sleep. I'm dubious, but the interviewee in the article claims they work well. 'Yves (not his real name), a 31-year-old software developer from Seattle, often doesn't have time for a full night's sleep. So he swallows something to make sure he doesn't need one.'" But, sleep is where I'm a Viking!

Stop Global Warming With Smog? 361

lkypnk writes, "The AP is reporting that Nobel Prize winning scientist Paul Crutzen has suggested deliberately spreading a layer of particulate matter in the upper atmosphere to help reflect some of the sun's energy in an effort to combat global warming. He reminds us that the eruption of the volcano Pinatubo in 1991 cooled the planet by as much as 0.9 degrees; he believes his computer simulations show a similar effect from deliberate injection of sulfur into the atmosphere by humans. Whatever the feasibility of the idea, as the president of the National Environmental Trust has said, 'We are already engaged in an uncontrolled experiment by injecting greenhouse gases into the atmosphere.'" From the article: "'It was meant to startle the policy makers,' said [Crutzen]. 'If they don't take action much more strongly than they have in the past, then in the end we have to do experiments like this.' ... Serious people are taking Crutzen's idea seriously."

Did Humans Get Their Big Brains From Neanderthals? 579

MCTFB writes, "According to CNN, human beings may have acquired a gene for developing bigger brains from Neanderthal man. Apparently, 70% of the world's population has a variant of a gene regulating brain size, with this variant being most common in people of European descent (where Neanderthal man lived alongside ancient humans), and least common in people of African descent (where Neanderthal man was non-existent). While modern day eugenicists might all too eagerly read into these findings to draw their own politically biased conclusions, people such as myself, who happen to be of northern European ancestry, may find it fascinating that somewhere in our lineage ancient humans and Neanderthals decided to make love and not war on the ancient plains of Eurasia."

Motorola Develops Bare-Bones Phone 293

tunabomber writes "Whenever a review of the latest cellphone/camera/MP3 player/GPS receiver/fish finder/tazer convergence gadget is posted on Slashdot, the first posters are usually quick to chime in by saying they just want something with decent battery life, reception, ergonomics, etc. Those posters' prayers may now be answered, because Motorola's new 'dumb' phone has been designed with these traits in mind. Notable features include an E Ink display and dual antennae to improve reception. The phone is slated to become available before the end of the year."

Microsoft Warns of PowerPoint Attack 127

narramissic writes to let us know about yet another PowerPoint flaw, this one affecting PowerPoint 2000, 2002, and 2003, soon after Microsoft issued a record number of patches to fix numerous Office vulnerabilities (among others). The new problem came to light in a blog posting by Microsoft Security Program Manager Alexandra Huft, but the coverage at ITWorld has more detail. Huft writes, "We've been made aware of proof of concept code published publicly affecting Microsoft Office 2003 PowerPoint," and goes on to say that Microsoft is not aware of any attacks that exploit the bug.

Natural Language Processing for State Security 132

Roland Piquepaille writes "Obviously, computers can't have an opinion. What computers are very good at, though, is scanning through text to deduct human opinions from factual information. This branch of natural-language processing (NLP) is called 'information extraction' and is used for sorting facts and opinions for Homeland Security. Right now, a consortium of three universities is for the U.S. Department of Homeland Security (DHS) which doesn't have enough in-house expertise in NLP. Read more for additional references and a diagram showing how information extraction is used."

Thrust from Microwaves - The Relativity Drive 567

dfenstrate writes "The latest New Scientist has an article about an engine that exploits relativity and microwaves to generate thrust. There is a working prototype." From the article: "Roger Shawyer has developed an engine with no moving parts that he believes can replace rockets and make trains, planes and automobiles obsolete ... The device that has sparked their interest is an engine that generates thrust purely from electromagnetic radiation — microwaves to be precise — by exploiting the strange properties of relativity. It has no moving parts, and releases no exhaust or noxious emissions. Potentially, it could pack the punch of a rocket in a box the size of a suitcase. It could one day replace the engines on almost any spacecraft. More advanced versions might allow cars to lift from the ground and hover."

Linguist Tweaks MS For Redefining "Genuine" 346

crazybilly writes, "The Language Log, home blog for several professional linguists, posted a story a few days ago about how Microsoft is redefining the word 'genuine' (as in the 'Microsoft Genuine Software Initiative') in an attempt to increase public sympathy for their anti-piracy efforts. From the article: 'An unlicensed copy of Microsoft Windows is perfectly genuine. It has exactly the same functionality as a licensed copy and was made by the same company... I suspect that Microsoft is attempting to redefine "genuine" because it has had a hard time getting sympathy for its actual complaint, namely unlicensed distribution.'"

Vaporizing Garbage to Create Electricity 492

CaroKann writes "Geoplasma is planning to build a power plant in St. Lucie County, Florida that will generate electricity by vaporizing landfill trash and sewage treatment plant sludge with plasma arcs. It will be the first plant of its kind in the USA and the largest in the world. The power plant is expected to destroy 3000 tons of garbage, generating about 120 megawatts of electricity per day. The plant will also supply steam to a nearby Tropicana juice plant. The landfill is expected to be depleted in about 18 years. In addition, up to 600 tons of melted, hardened sludge will be produced each day and will be sold for road construction."

Tumor-suppressing Gene Contributes to Aging 145

Van Cutter Romney writes "Scientists have discovered a tumor suppressing gene which also leads to aging in stem cells. The gene also known as p16INK4a when removed from 'knockout' mice resulted in older mice having organs as healthy as younger ones. However they didn't live any longer than normal mice. The new study was confirmed by three independent researchers from Harvard, UNC Chapel Hill and University of Michigan."

Amazon Unbox Video Store Launches 308

andrewl6097 writes "Amazon.com has launched it's Amazon Unbox video store. Looks like about 1300 movies and 350 tv series, at $9.99 and up for movies and $1.99 per TV episode. Downloads come with a DVD quality version and a version more appropriate for portable players (using Windows DRM). Also, videos can be re-downloaded from your Amazon media library. Cool!"

How Much Does Your Work Depend on the Internet? 322

malord asks: "I work for a small company that has recently had problems finding a stable internet connection. It started when we moved our office in order to upgrade our connection speed. We decided to go with cable internet through Comcast, since they offered the best speed for the price and told us that it would be available before we moved. Unfortunately, Comcast did not provide any service for two months after we moved, so we piggy backed on an existing (slow and unreliable) wireless account with another company in the meantime. When Comcast finally came around, the service that was provided was far from adequate with a consistent 30% packet loss and multiple disconnects everyday, which was confirmed through Comcast's tech support. Throughout this process, we have realized that having a reliable internet connection is more important than having a phone line and almost as necessary as electricity. What would you do if your internet was suddenly like dial-up for weeks at a time? How much money would your workplace lose if it was out for an hour or an entire day?"

Game Developers Missing Their Target? 184

wh0pper writes "Digital Trends is reporting that a recent survey finds that there aren't just 2 gamer markets, but instead a whopping 6. What does this mean? It means that game developers and publishers are ignoring a large portion of the gaming market by focusing on the traditional two segments: casual gamers and hardcore gamers. The 4 other game markets they identified are Social Gamers, Leisure Gamers, Dormant Gamers, Incidental Gamers. If you are wondering what those categories mean, the article gives descriptions of what each segment is. A surprising result from the survey is the importance of social gaming; video games are often considered a solitary activity, but Parks Associates' findings indicate a significant portion of the market views gaming as a social activity."

Morphine Relief Without Addiction? 308

Roland Piquepaille writes "Morphine has been used as a painkiller for decades, if not centuries. Unfortunately for patients, morphine is also an addictive substance. Now, Brigham Young University (BYU) chemists are using a vine plant that grows in Australia to develop a new painkilling molecule, but with fewer side effects. The Deseret Morning News reports that the BYU chemists hope to ease pain with hasubanonine, the synthetic compound they created and which has a similar molecular structure as morphine. Still, more tests need to be done before this natural drug can replace morphine."

Flying Robots Made From Cellophane? 148

Roland Piquepaille writes "Researchers have discovered that ordinary cellulose is a piezoelectric and smart material that can flap when exposed to an electric field. ScienceNOW reports that electricity can give life to cellophane. When you put a very thin layer of gold on each side of cellophane, and that you apply electric current to the gold layers, one positive, one negative, the cellophane curved toward the positive side. If you switch the voltage fast enough, the cellophane starts to act as a wing. So it should be possible to use it to build lightweight flying robots carrying cameras, microphones or sensors for surveillance missions. Read more for additional references and pictures about this electroactive paper (EAPap)."
