...ning in December, the survey team will search for tracks left by tigers as they traverse their home ranges looking for prey. A geographic database records the location and characteristics of each track reported, allowing specialists to estimate minimum numbers of tigers in the entire region.

The researchers presented subjects in the scanner with one of three types of movie clips: "context," "action," and "intention." The "context" clip came in two versions. In the first, a mug of...New imaging method gives early indication if brain cancer therapy is effective, U-M study shows
.... They used a magnetic resonance imaging scan that tracks the diffusion, or movement, of water through the brain and mapped the changes in diffusion from the start of therapy to three weeks later. The tumor cells block the flow of water, so as those cells die, water diffusion changes. In the study of 20 peo...Ophthalmologists and physicists team up to design 'bionic eye'
