Outcrop of long-sought rare rock on Mars found (June 4, 2010) -- A mineral-scouting instrument has found an outcrop of rock rich in carbonate minerals in the Columbia Hills of Gusev Crater on Mars. ... > full story
Electric fields make ceramic production quicker, cheaper, better (June 4, 2010) -- Researchers have found that applying a small electric field results in faster formation of ceramic products during manufacture at lower temperatures, and enhances the strength of the ceramic itself. ... > full story
Early Earth haze likely provided ultraviolet shield for planet (June 4, 2010) -- A thick organic haze that enshrouded early Earth several billion years ago may have been similar to the haze now hovering above Saturn's largest moon, Titan, and would have protected primordial life on the planet from the damaging effects of ultraviolet radiation. ... > full story
Soccer-playing robots get creative with physics-based planning (June 4, 2010) -- Robot soccer players are warming up to compete in this month's RoboCup 2010 world championship in Singapore. A new algorithm will help newly created robots to predict the ball's behavior based on physics principles. ... > full story
Students develop device to help blind maneuver (June 4, 2010) -- The radar system incorporates a computer, two video cameras and a scanning light source to warn the blind of obstacles with audible alerts. The system detects obstacles -- even those overhead -- by scanning the depth of its surroundings, taken from two different angles -- similar to that of the human eye. ... > full story
Online games new marketing tool for unhealthy foods (June 4, 2010) -- Public health researchers have found that children, who are already saturated with television messages about unhealthy food choices, are the targets of a new medium used to sell high-fat, high-sugar foods: advergames. ... > full story
First paper 'dipstick' test for determining blood type (June 3, 2010) -- Scientists are reporting development of the first "dipstick" test for instantly determining a person's blood type at a cost of just a few pennies. The test involves placing a drop of blood on a specially treated paper strip. ... > full story
On a roll: Designing the next rover to explore Mars (June 3, 2010) -- The concept of a wind-powered vehicle that can be used to explore the surface of Mars -- a "tumbleweed rover" -- has been around for more than 10 years, but there has been no consensus on exactly what that vehicle should look like. Now researchers have developed a computer model that allows engineers to test the attributes of different vehicle designs before creating costly prototypes for testing in real-world conditions. ... > full story
Astronaut's eye view: Mars Express orbiting the Red Planet (June 3, 2010) -- A new video shows what future astronauts would see from their cockpit: Mars turning below as they sweep around the Red Planet. Last month, ESA's Mars Express snapped images every minute to create a unique video that loops through a complete orbit of Earth's neighbor. ... > full story
Nanosponge drug delivery system more effective than direct injection (June 3, 2010) -- When loaded with an anticancer drug, a delivery system based on a novel material called nanosponge is three to five times more effective at reducing tumor growth than direct injection. ... > full story
Going underground to monitor carbon dioxide (June 3, 2010) -- A technique originally, applied to monitor the flow of contaminants into shallow groundwater supplies, has been repurposed to monitor carbon dioxide pumped deep underground for storage. ... > full story
Scientists create artificial mini 'black hole' (June 3, 2010) -- Chinese researchers have successfully built an electromagnetic absorbing device for microwave frequencies. The device, made of a thin cylinder comprising 60 concentric rings of metamaterials, is capable of absorbing microwave radiation, and has been compared to an astrophysical black hole (which, in space, soaks up matter and light). ... > full story
