While many physicists have predicted the existence of dark matter, a type of matter that does not absorb, reflect or emit light, so far no one has been able to observe it experimentally or determine its fundamental nature. ...
The use of face masks to help slow the spread of COVID-19 has been widely recommended by health professionals. This has triggered studies exploring the physics of face mask use and disease transmission, as well as investigations ...

Stars near the center of our galaxy are acting kind of weird. Dark matter may be the explanation.
Recently, Dr. Huo Zhipeng and his student Lu Yidong from Hefei Institutes of Physical Science of Chinese Academy of Sciences have created a new type of composite material for shielding against neutron and gamma radiation. ...
