eldavojohn writes "A fairly large breakthrough took place earlier this month with the most powerful man-made antimatter electron beam ever being created at North Carolina State University. Professor Hawari who worked on the project explains its benefits: 'The idea here is that if we create this intense beam of antimatter electrons — the complete opposite of the electron, basically — we can then use them in investigating and understanding the new types of materials being used in many applications.'"Read more of this storyat Slashdot.
eldavojohn writes "Researchers have created an electronic nose that can detect odor and identify which odors are a concern to it. From the article, 'The Lewis Group a division of Chemistry and Chemical Engineering at Caltech have a working model of an electronic nose. The efforts of Caltech scientists has led to an array of simple, readily fabricated chemically sensitive conducted polymer film. An array of broadly-cross reactive sensors respond to a variety of odors. However, the pattern of differential responses across the array produces a unique pattern for each odorant. The electronic nose can identify, classify and quantify when necessary the vapor or odor that poses a concern or threat.'"Read more of this storyat Slashdot.
Hugh Pickens writes "Even low levels of lead can cause brain damage, increasing the likelihood of behavioral and cognitive traits such as impulsivity, aggressiveness, and low IQ that are strongly linked with criminal behavior. The NYTimes has a story on how the phasing out of leaded gasoline starting with the Clean Air Act in 1973 may have led to a 56% drop in violent crime in the US in the 1990s. An economics professor at Amherst College, Jessica Wolpaw Reyes, discovered the connection and wrote a paper comparing the reduction of lead from gasoline between states (PDF) and the reduction of violent crime. She constructed a table linking crime rates in every state to childhood lead exposure in that state 20 or 30 years earlier. If lead poisoning is a factor in the development of criminal behavior, then countries that didn't switch to unleaded fuel until the 1980s, like Britain and Australia, should soon see a dip in crime as the last lead-damaged children outgrow their most violent years."Read more of this storyat Slashdot.
Tjeerd writes ""A Silicon Valley start-up is developing a hardware and software development platform for personal-assistant robots, autonomous boats and unmanned cars. The privately funded company, quietly started almost a year ago by eGroups founder and veteran Google architect Scott Hassan, plans to make its robotics software open source. That way, it hopes to draw a community of developers to build applications in these respective fields.""Read more of this storyat Slashdot.

hey0you0guy writes "China has launched its first lunar orbiter, on a planned year-long exploration mission to the Moon. Analysts say it is a key step towards China's aim of putting a man on the Moon by 2020, in the latest stage of an Asian space race with Japan and India. Earlier this month, a Japanese lunar probe entered orbit around the Moon. India is planning a lunar mission for April next year."Read more of this storyat Slashdot.
Science Daily is reporting that a new solar telescope has been launched via an enormous balloon filled with helium. Dubbed project "Sunrise" the National Center for Atmospheric Research (NCAR), NASA, Germany's Max Planck Institute for Solar Physics, Spain's Astrophysics Institute of the Canary Islands, and the Swedish Space Corporation all partnered to launch the balloon in order to view never before see features of the Sun. "The project may usher in a new generation of balloon-borne scientific missions that cost less than sending instruments into space. Scientists also can test an instrument on a balloon before making a commitment to launch it on a rocket. The balloon, with its gondola of scientific instruments, was launched successfully on the morning of October 3 from the Columbia Scientific Balloon Facility in Fort Sumner, New Mexico. It flew for about 10 hours, capturing stable images of the solar surface and additional data from the various instruments of the sophisticated payload. The gondola then separated from the balloon and descended with a parachute, landing safely in a field outside Dalhart, Texas."Read more of this storyat Slashdot.
coondoggie writes "If you build it, NASA will not only come, it'll give you $2 million dollars for your troubles. The space agency today said it will offer $2 million in prizes if competing teams can successfully build a lunar lander at the Northrop Grumman Lunar Lander Challenge at Holloman Air Force Base, in Alamogordo, N.M. Oct. 27 and 28th. To win the prize, teams must demonstrate a rocket-propelled vehicle and payload that takes off vertically, climbs to a defined altitude, flies for a pre-determined amount of time, and then lands vertically on a target that is a fixed distance from the launch pad. After landing, the vehicle must take off again within a predetermined time, fly for a certain amount of time and then land back on its original launch pad."Read more of this storyat Slashdot.

swordgeek writes "Comet 17P/Holmes, a relatively obscure and (until a few days ago) dim object, has suddenly flared to be literally a million times brighter, going from magnitude 18 to 2.8. It is just outside of the constellation Perseus, which puts it high in the sky and ideal for viewing at this time of year. The comet still appears starlike even in binoculars but should grow to several arcminutes across over the next few nights. The comet is now readily visible to the naked eye. This is a completely unexpected once-in-a-lifetime event, so get out your finest optics (even if it's just your eyes) and go comet watching!"Read more of this storyat Slashdot.
The Technology Review site has up an article on new software that can do quantitative analysis of facial expressions, detecting whether a person is smiling. The software was developed by the Omron Corporation, and can also estimate a subject's age and gender, or verify a person's identity from a database. Though the company doesn't yet know whether it plans to release the software commercially, there are a number of obvious applications. "Omron envisions the smile software being used in marketing, perhaps to evaluate consumers' reactions to a new product or to an advertising campaign. A smile checker could also help train customer-service staff to meet Japan's legendarily high standards ... A smile in isolation is easy to detect, but the bigger challenge is to develop systems that can recognize the concerto of facial actions that make up complex expressions like confusion, fear, and disgust."
