A COMPANY has developed a hypersonic hydron-powered passenger jet that could reduce flight time from America to Australia to just under four hours.

The European startup Destinus has been testing a prototype for several years and completed a successful test flight of a prototype at the end of 2022.

The Flying-V airplane doesn’t look like anything you’ll find at today’s airports, but it could be the future of aviation.

Identifying new sources that produce electrons faster could help to advance the many imaging techniques that rely on electrons. In a recent paper published in Physical Review Letters, a team of researchers at Eindhoven University of Technology demonstrated the scattering of subpicosecond electron bunches from an ultracold electron source.

“Our research group is working to develop the next generation of ultrafast electron sources to push imaging techniques such as ultrafast electron diffraction to the next level,” Tim de Raadt, one of the researchers who carried out the study, told Phys.org.

“The idea of using laser-cooled ultracold gas clouds as an electron source to improve the state-of-the-art in brightness was first introduced in a paper published in 2005. Since then, research efforts have produced multiple versions of such a ultracold electron source, with the most recent one (used in this work) focusing on making the source compact, easy to align and operate, and being more stable, as described in another past paper that also studied the transverse electron beam properties.”

A new supernova has turned into the most watched phenomenon in the May night sky. The close proximity of the stellar explosion and the vast amount of observations gathered since the discovery promise to advance astronomers’ understanding of stellar evolution and could even lead to major advances in supernova forecasting.

Supernovas are powerful explosions in which very massive stars, at least eight times more massive than our sun, die when they use up all the hydrogen fuel in their cores. The discovery of this latest exploding star, known officially as 2023ifx, was a serendipitous one.

At a certain point, it was starting to feel like Netflix’s proposed crackdown on password sharing was a bluff, that they would never actually go through with it, right?

Well, the time has come, and the new anti-password sharing system has reached the US at last. No more testing, it’s time to nuke those extra accounts.

Upcycling a vintage milling machine for CNC control while adding a fourth axis isn’t for the fainthearted, but the results are impressive.

Meta had to sell GIPHY after UK regulator blocked the deal last year.

Shutterstock announced Tuesday that it will buy animated-image platform GIPHY from Meta for $53 million in cash. The deal is a significant loss for Meta, which had reportedly paid around $400 million to acquire the New York-based GIF search engine in 2020.

This development comes a year after the deal was challenged by the UK’s Competition and Markets Authority, which had ordered Meta to sell Giphy over anti-competitive practices.
