Dec 11, 2023 by News Staff

The rapid neutron capture process, or the so-called r-process, occurs in neutron-rich environments such as neutron star mergers or certain types of supernovae. This process is thought to produce many of the chemical elements heavier than iron, but the details are poorly understood and cannot be studied in the lab. In new research, Los Alamos National Laboratory theoretical physicist Matthew Mumpower and his colleagues analyzed r-process element abundances...

Mendieta et al. used fMRI to measure brain activity in fans of rival soccer teams during match play. This image shows the contrast of winning and losing in the ‘good fanatic brain.’ It shows in warm colors the activity related to a significant victory. The blue scale represents the activation related to a significant loss; this pattern is congruent with the Mentalization Network, which suggests a rationalization process of the pain evoked by the losing scenario.
