Our lilacs are blooming here in the Boston area. What's blooming in your yard?
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

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...
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.

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

“Drop that baby!” My watercolor of Leptoceratops defends their young against Quetzalcoatlus. I do think smaller ceratopsians were punching above their weight class and made sure to convey it here. #paleoart #sciart
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.
