Top Dark Matter Candidate Loses Ground to Tiniest Competitor

November 27, 2019

Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.

A brain full of “explosive” activity may lead to an earlier death than one with steadier “candles” of activity.
