Fastest-ever study of how electrons respond to X-rays performed

A study of electron dynamics timed to millionths of a billionth of a second reveals the damage radiation can do on a molecular level.

The first-of-its kind study used ultrafast X-ray pulses to disrupt the electrons in a molecule of nitrous oxide and measure the resultant changes with unprecedented accuracy.

The work, published today in Science, was performed at the Linac Coherent Light Source (LCLS) at the Stanford Linear Accelerator Centre (SLAC), Stanford, U.S. and was supported by a team of five scientists from Imperial College London.

Aero Likely the First in a Series of Enthusiast VR Headsets from Varjo

Varjo’s Aero headset is the first from the company that’s meant to appeal to individual customers rather than large organizations… and it probably won’t be the last.

Since the company’s inception, Varjo has sold high-end enterprise headsets to the likes of Fortune 500 companies. That is until just last month when the company started shipping its new Aero headset which was not only substantially cheaper but was, for the first time, sold without any kind of annual upkeep fee which made the company’s other headsets a non-starter for individual buyers.

And while it’s possible the company had formulated Aero as a sort of one-off experiment, it seems Varjo has been satisfied enough with the reception that it intends for Aero to become an ongoing series of headsets for the high-end enthusiast segment.

Five of the most exciting telescope pictures of the universe

Some of these objects are among the oldest and most distant known. Here we’re seeing light from ancient stars whose local contemporaries have long since been extinguished.

The oldest galaxies formed during the epoch of reionisation, when the tenuous gas in the universe first became bathed in starlight which was capable of separating electrons from hydrogen. This was the last major change in properties of the universe as a whole.

The fact that light carries so much information, allowing us to piece together the history of the universe, is remarkable. The launch of the James Webb Space Telescope will give us some vastly improved infrared images, and will inevitably raise new questions to challenge future generations of scientists.
