With the whoosh of compressed gas and the whir of unspooling wire, a team of Boulder scientists and engineers tested a new instrument prototype that might be used to detect groundwater deep inside Mars. The Mars Time Domain Electromagnetic Sounder (MTDEM) uses induction to generate electrical currents in the ground, whose secondary magnetic fields are in turn detected at the planetary surface. In this way, the electrical conductivity of the subsurface can be reconstructed. "Groundwater that...

It's common for retailers to bundle two different products (like razors and blades) together and describe one as free. A new study in the Journal of Consumer Research shows that this strategy leads consumers to devalue the items when they're sold individually.Authors Michael A. Kamins (Stony Brook University-SUNY), Valerie S. Folkes (University of Southern California), and Alexander Fedorikhin (Indiana University) found that describing a bundled item as free decreases the amount consumers are...

"Physically active transport is probably our best bet for helping populations at risk of heart disease and diabetes to increase physical activity levels, since we have to spend time getting to and from work anyway," says Dr Erik Hemmingsson, who led the research.The study was carried out at the Obesity Unit at Karolinska University Hospital in Stockholm and lasted 18 months. It involved 120 obese and unfit women between the ages of 30 and 60 with a waist circumference of at least 88...

Wolfram Alpha, a web tool that some experts believe could be as important as Google, has made its first public appearance, BBC News reported. British-born physicist Stephen Wolfram created the free program, a technology known as "computational knowledge engine," that attempts to answer questions directly, rather than display web pages in response to a query like a search engine. The program will be available to the public from the middle of May this year. Dr. Wolfram said during the...

Scratches on an otherwise perfect looking vehicle can be a real annoyance for car owners, but scientists have developed a polyurethane coating that heals its own scratches when exposed to sunlight."We developed a polymeric material that is able to repair itself by exposure to the sun," said Marek Urban of the University of Southern Mississippi in Hattiesburg. The findings are published in the journal Science.The report says the self-healing coating uses chitosan. It's a substance found in the...

Following trends is a lifesaving instinct, at least for birds, and provides clues that can be applied across the animal kingdom. New research from Universit© de Montr©al published in Biology Letters, shows that Herring and Ring-billed gulls not only watch their neighbours "“ they mimic their behaviour to assure their survival. Contrary to previous beliefs, this study suggests that animals don't necessarily act independently and that they cue on reactions from other members of...
