First a hydrogen leak. Now a separate *helium* leak is causing a delay in NASA's Artemis 2 mission around the Moon.

The giant rocket is rolling off the launch pad, with the flight delayed to April 1 at the earliest.

5 of the 22 species of #bumblebee found in #Alaska are tundra habitat specialists. These hardy #bees have thrived in territories that are harsh even by Alaskan standards but now may face problems due to climate breakdown.

We've arranged a #society based on #science and #technology, in which nobody understands anything about science and technology. And this combustible mixture of #ignorance 🙈 and #power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a #democracy if the people don't know anything about it ? https://en.wikiquote.org/wiki/Carl_Sagan

For decades, SETI Institute scientists have turned to Earth’s most extreme environments to understand how life persists at the edge of what biology allows. Now, scientists have revived microscopic worms frozen in Siberian permafrost for roughly 46,000 years, revealing how life can survive extreme cold through a state of cryptobiosis. Simon Steel spoke with evolutionary biologist Philipp Schiffer about the discovery.

Have you ever seen electrons? Watch this!

I got an old Narva BR-2 cathode ray tube (Braun'sche Röhre) that was made for educational purposes. It has some Neon gas inside that makes the electron beam visible.
The second tube in this video is a voltage regulator OD3A that also "glows" nicely.
