New Technique for Tracking Gene Regulators

...ve, and take a very long time.Scientists have been working on short cuts, but all so far have limits.For example, in one recent technique, scientists mix the regulatorprotein of interest (let’s say, CREB) with the entire genome of a celland let it bind. Then they fragment the genome into smaller pieces, 500t...

U-M scientist to talk about tissue engineering at AAAS

...roach works, Krebsbach said the next step would be working with engineers to develop anatomically correct scaffolding with the same curvature and contours of natural bones. That would help a patient develop new bone almost indistinguishable from nature's original equipment. Many researchers at University of...

Scientists seek answers on what activates deadly anthrax spores

... bacteria, as well as humans. The researchers are working with a non-pathogenic strain of anthrax. The genome sequences of four strains of the bacteria, known scientifically as Bacillus anthracis, have been determined. The group also will be exploring the three-dimensional structures and the functions of t...
