Archaeologists Keep Finding Massive Shoes at an Ancient Roman Fortβ€”and They Have No Idea Why They're So Big Discovered near Hadrian's Wall in northern England, the oversized leather footwear has left researchers puzzled

Looked out the back window this morning to see a beautiful wild turkey checking out our bird feeder and back yard. It's great to see them here in suburbia.

Kip Siegel, founder of KMS Fusion, died just over 50 years ago after suffering a stroke while trying to persuade Congress to support his company's laser fusion tech. Livermore now has ignited seven fusion targets. That's progress, but will fusion energy take 50 more years? alchetron.com/Kip-Siegel

Did a Ring of Rocks and Dust Orbit Earth Before the Dinosaurs Roamed? A team of scientists thinks a clustering of ancient impact craters points to a temporary ring around Earth hundreds of millions of years ago.

Sky & Telescope is one of only five monthly magazines that has published regularly for 80 years. The February 2025 issue was number 1000, and I had a story in the that print issue on the theory that Earth may have had a ring in it. skyandtelescope.org/astronomy-ne...

Against the odds: 12 women who beat bias to succeed in science A book deftly highlights how women have been considered unsuitable as researchers for reasons other than their ability and commitment.

In Against the Odds, John and Mary Gribbin say a lack of women's toilets held back women in science. In 1969 the Caltech faculty told a committee on admitting women undergraduates in 1969. A plumber could solve that problem, and the first women were admitted in 1971. www.nature.com/articles/d41...

Why Is Mars Red? Martian dust is red because of rust β€” but the rust on Mars is not the same iron oxide mineral found on Earth.

The rusty dust on Mars is different than terrestrial rust. It's a different iron oxide ferrihydrite that isn't stable on Earth, but it can survive billions of years on Mars which is very much colder. Neat stuff skyandtelescope.org/astronomy-ne...

Remembering Human Error Specialist James Reason | Aviation Week Network James Reason was a leader in recognizing many mistakes as expected occasional outcomes rather than seeing all errors as intentional, deviant acts.

Vacuum tubes are back! Today I found the local electronics store is selling antiques -- vacuum tubes from the mid-20th century, many in their original boxes. I hadn't seen vacuum tubes on sale in a store for decades. Thanks to You-Do-It-Electronics for the blast from the past.
