Plain silicon grating reveals a hidden 'twist' in light from electron beams

In 1953, two physicists showed that an electron beam skimming past a grating emits light whose color depends only on the electron's speed and the grating's spacing. Known as Smith-Purcell radiation, this phenomenon has become ...

Rare fossils reveal what ancient Denisovans may have looked like

Whenever anything is written about the Denisovans, the word "mysterious" is almost guaranteed to appear. That is because we just don't know a lot about this extinct human group that may have lived in East Asia from at least ...

Black holes spinning near maximum rate could split in two, calculations suggest

Two black holes can collide and merge into one. But could the opposite happen: could a single black hole split into two smaller ones? That question is explored in a new theoretical study: "When Black Holes Admit Pair-of-pants ...
