An anonymous reader writes Researchers have found that a chemical found in hops may actually improve memory. Unfortunately, a person would need to drink 3,520 pints of beer a day to get a high enough dose of the chemical to boost their brain power. A daunting task for even the most enthusiastic Oktoberfest participant. From the article: "Researchers at Oregon State University discovered that doses of xanthohumol, a flavonoid found in hops, improved memory and thinking in a lucky group of mice. Flavonoids are a class of compounds present in plants, known to have numerous health benefits. Last year, researchers discovered that a flavonoid found in celery and artichokes could potentially fight pancreatic cancer. The researchers treated the mice with dietary supplements of xanthohumol over the course of eight weeks. Their goal was to determine if xanthohumol could affect palmitoylation, a naturally occurring process in animals (including humans) that's associated with memory degradation. The mice then went through a series of tests—including the popular Morris water maze—to gauge whether or not the treatments had improved their spatial memory and cognitive flexibility. For the younger mice in the group, it worked. But on the older mice, unfortunately, the xanthohumol didn't seem to have any effect."Read Replies (0)

sends this news from the EFF:For years, local law enforcement agencies around the country have told parents that installing ComputerCOP software is the "first step" in protecting their children online. ... As official as it looks,ComputerCOP is actually just spyware, generally bought in bulk from a New York company that appears to do nothing but market this software to local government agencies. The way ComputerCOP works is neither safe nor secure. It isn't particularly effective either, except for generating positive PR for the law enforcement agencies distributing it.
As security software goes, we observed a product with a keystroke-capturing function, also called a "keylogger," that could place a family's personal information at extreme risk by transmitting what a user types over the Internet to third-party servers without encryption. EFF conducted a security review of ComputerCOP while also following the paper trail of public records to see how widely the software has spread. Based on ComputerCOP's own marketing information, we identified approximately 245 agencies in more than 35 states, plus the U.S. Marshals, that have used public funds (often the proceeds from property seized during criminal investigations) to purchase and distribute ComputerCOP. One sheriff's department even bought a copy for every family in its county.Read Replies (0)

An anonymous reader writes: You may recall Cody Wilson as the man behind the world's first 3D-printed gun. He built a company behind the ideals of DIY gun-making, and now he's come back with another device: the "Ghost Gunner," a CNC mill designed to create the lower receiver of an AR-15 rifle. "That simple chunk of metal has become the epicenter of a gun control firestorm. A lower receiver is the body of the gun that connects its stock, barrel, magazine and other parts. As such, it's also the rifle's most regulated element. Mill your own lower receiver at home, however, and you can order the rest of the parts from online gun shops, creating a semi-automatic weapon with no serial number, obtained with no background check, no waiting period or other regulatory hurdles. Some gun control advocates call it a "ghost gun." Selling that untraceable gun body is illegal, but no law prevents you from making one." Wilson's goal is still to render government gun regulation useless, even as debate rages on banning this kind of manufacturing.Read Replies (0)

An anonymous reader writes: In 2000, NASA began taking satellite images of the Aral Sea in central Asia, which was once the fourth-largest inland lake in the world. At that time, there was an expansive eastern basin, and smaller basins to the north and west. In images recorded just last week, we see that the eastern basin is completely gone, and the western basin just a thin strip of water. The local fishing industry has been devastated, old ship graveyards now rest on dry ground, and salt-heavy sand is being blown around the region, causing health issues.
Most of the lake's decline is attributable to human intervention: "In the 1950s, two of the region's major rivers – the Amu Darya and and the Syr Darya – were diverted by the Soviet government to provide irrigation for cotton production in Uzbekistan and Turkmenistan, starving the Aral. It has been diminishing ever since, with the sea level dropping 16 meters between 1960 and 1996, according to the World Bank. Water levels are believed to be down to less than 10 per cent of what they were five decades ago." Low levels of rain and snow didn't help.Read Replies (0)
