Nanocosmetics Used Since Ancient Egypt 252

Posted by ScuttleMonkey from the lead-good-for-the-skin dept.
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

Posted by Zonk from the hold-still-for-your-interrogation dept.
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."

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

Posted by ScuttleMonkey from the too-many-hours-looking-through-a-telescope dept.
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."
