Researchers have designed a smart drug that hunts down and breaks a little-known RNA that cancer cells depend on. The drug recognizes a unique fold in the RNA and triggers the cell to destroy it.

Researchers say they have recovered RNA from the remains of a woolly mammoth that lived roughly 39,000 years ago.

Scientists have managed to rescue the molecule, against all odds, from a calf that died after being attacked by cave lions ...
