...t x-ray beams provide the ability to study smaller objects at higher resolution," said SSRL physicist John Arthur. "In many cases the greater brightness at SPEAR3 will also enable researchers to take their data faster, do more difficult experiments, and use smaller samples of material." Thirty years ago, SSR...Physicists use fractals to help Parkinson's sufferers
...ls are usually associated with irregular geometric objects that look the same no matter what scale they are viewed at: clouds, branching trees, rugged coastlines, rocky mountains, are all examples of fractals. The idea of a fractal can also be applied to irregular motion. For instance, a healthy heartbeat is...New study suggests brains of autistic children can be trained to recognize faces

ANAHEIM, Calif.--Like many objects of curiosity in the nanoworld, the DNA molecule has defied visual scrutiny because it lies beyond the "diffraction limit"--a 200 nanometer cutoff where the too-tiny escapes resolution by an optical microscope. Dehong Hu and Peter Lu, scientists at th...New method for determining age of artifacts fills chronological gap for scientists
