Proteins are the molecular workhorses of cells. To understand their functions, scientists soon realized that they had to figure out proteins’ shapes. But solving a protein structure is a challenging ...

An artistic representation of antihyperhydrogen-4 — an antimatter hypernucleus made of an antiproton, two antineutrons, and an antilambda particle — created in a collision of two gold nuclei (left).

Uh, NO. Obviously antimatter doesn't move backward in time. The point is that the fundamental laws of nature appear time reversable at the micro-scale -- you can "play a movie" of the "scattering" ...

GENEVA (AP) — Scientists in Geneva took some antiprotons out for a spin — a very delicate one — in a truck, in a never-tried-before test drive that has been deemed a success. Pope calls for robust ...

A small amount of antimatter took to the road on Tuesday, representing the first time any quantity of the world’s most expensive, volatile and rare substance has been moved. The breakthrough opens the ...

Our universe is filled with particles, such as electrons and protons, which make up all the stuff on our planet and beyond: animals, plants, people, planets, asteroids, stars, gas clouds, and galaxies ...

Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and 'antimatter' -- particles that are matter counterparts but with opposite charge. But then, as ...

For various, typically historical reasons, even the best physicists claim things that sound egregious to modern observers. That doesn’t necessarily mean these ideas are completely useless—if anything, ...
