Amazing nanotech in Boston: Weighing DNA, digital heat flow, electromechanical butterfly images
...echnology---electronic and mechanical devices with dimensions at the nanometer scale---is especially valuable for sensing single molecules. Using small NEMS detectors makes analysis or detection faster, and requires only tiny amounts of sample material to make good measurements. But the main motivation is NEMS'...Bacteria which sense the Earth's magnetic field
...gists from Martinsried had already imaged in three dimensions in other cells. This shed light on the crux of the problem with the magnetosome chain: although in the wild type, the magnetosomes lay like pearls on a string along the filament, in the cells missing MamJ, the empty magnetosome vesicles scattered the...A distinguished program training the next generation of conservation scientists
