The radius of an electron is approximately 2 x ... during the decay of nuclides that have an excess of protons in their nucleus. When decaying takes place, these radionuclides emit a positron ...

In 2010, atomic physicists at the Paul Scherrer Institute (PSI) in Switzerland measured the radius of a proton in muonic hydrogen and found it was smaller than previously thought. This unexpected ...

Biophysical simulations showed that a relatively small number of KIF21B molecules can restrict mirotubule length and promote an imbalance of dynein-mediated pulling forces that allows the centrosome ...

The subthalamic nucleus (STN) is hypothesized to play a central role in the rapid stopping of movement in reaction to a stop signal. Single-unit recording evidence for such a role is sparse, however, ...
