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 ...

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 ...

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" ...

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 ...

Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles of matter and antimatter decay. By Kenneth Chang Understanding why matter ...
