Can neutrinos help explain what's the matter with antimatter?

In physics, antimatter is simply the "opposite" of matter. Antimatter particles have the same mass as their counterparts but with other properties flipped; for example, protons in matter have a positive charge while antiprotons ...

Why does El Niño decay faster than La Niña?

Warm and cold phases of El Niño-Southern Oscillation (ENSO) exhibit a significant asymmetry in their decay speed. Generally, El Niño tends to turn into a La Niña event in the following June-July after its mature phase; ...

Physicists reveal why matter dominates universe
