Invading black hole or neutron star caused star to explode, say astronomers

Physics World: A black hole or a neutron star may have merged with a normal massive star and caused it to explode in a supernova, according to Caltech’s Dillon Dong…

Unraveling D-Meson Mixing

Physics: Since the construction of the first particle accelerators, increasing the energy of those accelerators has allowed physicists to produce and discover heavier and heavier particles. Those discoveries have extended our knowledge of the subatomic world and eventually resulted in the theoretical framework called the standard model. New particles…

Emilie Ringe: Plasmonics pioneer is harnessing the potential of magnesium nanoparticles

C&EN: In 2018, Emilie Ringe had a pivotal year in her work with plasmonic nanoparticles. These tiny specks of matter act like antennas for light, gathering and concentrating energy…

Quantum Solution to Classical Drag Puzzle

Physics: An object moving through a fluid normally generates “drag forces,” which act to slow its motion, yet researchers still disagree about subtle aspects of the origin of such forces. New research has made a surprising connection to quantum physics,…
