...ELECTRON-BEAM COMPUTED TOMOGRAPHY...
Until now. It turns out that excess deposits of calcium in the lining of the arteries, which can be measured using electron-beam computed tomography (EBCT), are a good indication that potentially dangerous fatty plaques exist. The correlation is strong enough that the American Heart Association is weighing a recommendation of EBCT screening for healthy adults who have a greater than average risk of heart disease, including smokers and those with a strong family history. As an added benefit, patients can take home their EBCT image, complete with gummed-up arteries, and use it as a reminder to stick with...
...cantilever is coated on one side with a chemical that specifically binds a target molecule--say, a cancer-related protein or a plastic explosive. When that molecule sticks to it, the cantilever bends and the frequency of its vibration changes, which can be measured by bouncing a laser beam off its surface. Thundat and his team are only months from completing an exquisitely sensitive handheld detector that will suck in air and search for a variety of explosives. Since the cantilever sensors are carved out with the same technology used to build computer chips, the detector should ultimately cost only...
Instead of using a single control beam, as was done in the previous studies, two beams were used, Bajcsy said...
...ability of the laser beam to create plasma within the cell, vaporizing matter in the process, makes it invaluable in the field of mechanobiology—which is primarily concerned with the importance of mechanics and structure in the regulation of cell form and function, as well as tissue development, Ingber said...
