Antimatter Reacts to Gravity in the Same Way as Ordinary Matter, Physicists Find
In the 95 years we’ve known about antimatter, physicists have not tested how the elusive inverse of ordinary matter is affected by gravity, the force that pulls masses to Earth and seems to affect all things in the classical realm. Now, a group of physicists have. Members of the Antihydrogen Laser Physics Apparatus (ALPHA) collaboration…

10 Years After the Higgs Boson, What’s the Next Big Thing for Physics?
On July 4, 2012, scientists at CERN confirmed the observation of the Higgs boson, an elementary particle first proposed in the 1960s. The boson’s discovery was a momentous occasion, as it meant physicists were a step closer to probing the field associated with the boson, which gives particles mass.

Russians Barred From New Large Hadron Collider Experiments Over Ukraine Invasion
The CERN Council convened today to discuss how Russia’s invasion of Ukraine affects the scientific collaboration’s ability to pursue its goals and ensure the safety and wellbeing of its members. The council meeting resulted in a resolution to condemn the Russian invasion, to suspend Russia’s Observer status to the council, and to not begin new…

Physicists Detect Neutrinos for First Time Ever Using Large Hadron Collider
Last week, a team of physicists working in CERN’s Large Hadron Collider announced the facility’s first-ever detection of neutrinos, which are some of the smallest, most weakly interacting particles yet proven to exist.
