Transmission electron microscopy reveals the architecture of cells at nanometer resolution, but chemical fixation severely warps their native structure. The true ultrastructure of cells can be ...

Pulsars are among the most exotic celestial bodies known. They have diameters of about 20 kilometers, but at the same time roughly the mass of our sun. A sugar-cube sized piece of its ultra-compact ...

A team of neuroscientists has found that the human brain can process a dozen pictures that the eye sees for as little as 13 milliseconds. In the new study, researchers asked subjects to look for a ...

A new approach to magnetic resonance imaging could allow neuroscientists to noninvasively track the propagation of brain signals on millisecond timescales, according to a study published yesterday ...
