Sad to hear of the passing of Wolfgang Kaiser, one of the last of the early laser pioneers.

That's more like it.

Went to the local electronics store today and found they are selling vintage -- no, antique -- vacuum tubes for electronics. I hadn't see vacuum tubes on sale in decades. Are they coming back?

Does using GPS rot your brain? Not exactly, but finding your own way around may exercise it enough to stave off dementia. zdnet.com/article/worrie…

There are few things as exciting in our little corner of science as a new specimen of Archaeopteryx...with a skull...in a major, easily accessible museum! Congratulations to Field Museum & Jingmai O'Connor! These lovely photos are from this great article: bit.ly/44w9Z64

A surprise in the inner part of the main asteroid belt -- NASA's Lucy mission found the 720-meter asteroid Dinkinesh has a contact binary moon with two twin lobes locked in orbit. skyandtelescope.org/astronomy-news…

Very sorry to hear of the passing of Ed Stone, jpl.nasa.gov/news/ed-stone-… Voyager project scientist, former JPL director and one of the greats of space science. Before that he was my freshman physics TA at Caltech, and a great teacher as well. He will be missed.

Ai has no place in science or in scientific illustration!!!

This was a tragic (but really well reported) article in Tech Review. When I was working on Plastic Fantastic, some physicists said, this (2002 fraud) case was isolated and will be unlikely to recur as we can easily address the enabling factors. Go figure. technologyreview.com/2024/05/15/109…

Training AI on AI-generated documents churns out gibberish, reports a Nature paper. nature.com/articles/d4158…? Pretty damn obvious and very dangerous.

Today is the day. The hearing. A chance to put the case. To convince them that this is imperative. That it is worth the cost. That we owe the debt to those who went before. That it is our destiny. We must create a new colony on Mars. #scifi by Jeff Hecht nature.com/articles/d4158…

“Leopard spots” on a Mars rock could come from life — or they could simply be a sign of a type of chemical reaction that requires water. Read more from Jeff Hecht here: buff.ly/3SDlOTd
