Florida man is world's fastest flasher: Just 53 quintillionths of a sec

Physicists at the University of Central Florida have developed the world's fastest X‑ray pulse, at 53 attoseconds. Blink and you'll really, really miss it. At 53 quintillionths (53 x 10‑18) of a second, the flash is 15 orders of magnitude faster than the blink of an eye. The beam travels less than one-thousandth of the …

Forget Iran and North Korea. Now there's another uranium source

Astronomers have proposed that heavy elements in the universe may have been forged when small, primordial black holes swallowed neutron stars. Boffins widely believe that elements lighter than iron are formed during nuclear fusion reactions in the cores of stars, or during supernova bursts. But to create elements heavier than …

Cancel your summer trip to nearby Proxima b. No chance of life, room service, say boffins

NASA scientists have dashed hopes that Proxima Centauri b, an Earth-ish-like planet orbiting the closest star to the Sun, could be habitable. Last year, it emerged there was a rocky exoplanet, dubbed Proxima Centauri b, within Proxima Centauri's crucial Goldilocks zone – meaning there was an alien world in the sweet spot …
