Defying Longstanding Chemical Rules, Chemists Have Engineered Exotic Molecules They Say Could “Benefit Our World”

UCLA researchers have violated Bredt’s rule, a century-old principle of organic chemistry, challenging our understanding of molecular shapes.

Atoms Don’t Sit Still: Scientists Catch Them Roaming Before X-Ray Damage Strikes

Researchers have uncovered how atoms subtly rearrange themselves for up to a trillionth of a second before releasing low-energy electrons after X-ray excitation.
