Asteroid loaded with amino acids offers new clues about the origin of life on Earth
One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of life—were transported ...
Rapid X-ray pulses enable 100-fold efficiency boost for photoionization
Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a short-lived window of opportunity opens. For just a few femtoseconds, before an electron fills the void ...
