New from the Education Board, the poster "Look at our Microscopic World" features the dissecting, light, fluorescent and electron microscopes. A peek into each microscope shows the diversity of the unseen world from human cells to bacterial spores. Visually appealing and fun, the poster is directed to middle school students. Don’t miss the chance to hang a poster in your local school ...

... cells from the body, reprogram them to attack malignant tissues, and return them to the body. However, more than 90 percent of reinjected cells have died before having any effect in experiments. The microscopic implants developed by Mooney’s group are 8.5 millimeters in diameter and made of an FDA-approved biodegradable polymer. The devices which are a shockingly ninety percent air are ...

... ) -- Many hands -- or many flagella -- make light work. In studies of the motion of tiny swimming bacteria, scientists at the U.S. Department of Energy's Argonne National Laboratory found that the microscopic organisms can stir fluids remarkably quickly and effectively. As a result, the bacterial flagella could act like tiny motors to mix chemicals in biomedical kits, among other applications.
