Creating Water from Thin Air 348

Iphtashu Fitz writes "In order to provide the U.S. Military with water in places like Iraq, the Defense Advanced Research Projects Agency gave millions of dollars in research funding to companies like LexCarb and Sciperio to try to extract water from the air. Amazingly, a company that DARPA didn't fund, Aqua Sciences, beat them all to the punch by developing a machine that can extract up to 600 gallons of water a day from thin air even in locations like arid deserts. The 20 foot machine does this without using or producing toxic materials or byproducts. The CEO of Aqua Sciences declined to elaborate on how the machine works, but said it is based on the natural process by which salt absorbs water."

Nanocosmetics Used Since Ancient Egypt 252

Roland Piquepaille writes "French researchers have found that Egyptians, Greek and Romans were using nanotechnology to dye their hair several thousands years ago. Nanowerk Spotlight reports they were using lead compounds which generated lead sulfide (PbS) nanocrystals with a diameter of only 5 nanometers. At a moment where many people wonder if the use of nanoparticles is safe, it's good to know that nanotechnology has been widely used for a very long time."

NH Man Arrested for Videotaping Police 1232

macinrack writes to mention a story about a New Hampshire man who was arrested for videotaping police on his doorstep, using a fairly standard security camera system. He was officially charged with 'two felony counts of violating state eavesdropping and wiretap law by using an electronic device.' From the article: "The security cameras record sound and audio directly to a videocassette recorder inside the house, and the Gannons posted warnings about the system, Janet Gannon said. On Tuesday night, Michael Gannon brought a videocassette to the police department, and asked to speak with someone in 'public relations,' his wife said and police reported. Gannon wanted to lodge a complaint against Karlis, who had come to the family's house while investigating their sons, Janet Gannon said. She said Karlis showed up late at night, was rude, and refused to leave when they asked him."

Deep Brain Stimulation as Depression Treatment 273

Neopallium writes "Medtronic, today announced its intentions to pursue a major clinical trial of the company's deep brain stimulation (DBS) technology in the treatment of severe and intractable depression, a disabling form of the psychiatric disorder affecting millions of people worldwide. "While not a cure, DBS has allowed these patients to return to much more functional and happy lives," said Dr. Rezai, who represented an international working group of physicians that has been studying the application of DBS therapy in the treatment of intractable depression and OCD in collaboration with Medtronic."

Blue Ring Around Uranus 269

ZedNaught writes "The BBC is reporting that 'astronomers have discovered that the planet Uranus has a blue ring - only the second found in the Solar System. Like the blue ring of Saturn, it probably owes its existence to an accompanying small moon.' According to the April issue of Science, the blue ring is one of two new outer rings recently discovered around Uranus using the infrared Keck adaptive optics system. The rings are blue and red like Saturn's E and G rings. The blue ring around Saturn hosts the moon Enceladus while the Uranus ring contains the moon Mab."
