“Controls on ozone-depleting chemical compounds…are driving the gradual recovery of the ozone layer, which remains on track to recover fully later this century as countries around the world replace ozone-depleting substances with less-harmful alternatives.”

On Sept. 23, NASA’s OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification, and Security – Apophis Explorer) spacecraft flew within 2,136 miles (3,438 kilometers) of Earth. Video and details: go.nasa.gov/4ofmdIw (Let's hope they don't cancel this mission.)

Good news, and the culmination of years of research into preventing food allergies.
The article doesn’t mention it, but the original impetus for this research came from an alumnus of my high school, Gideon Lack. 🧪

Took the rainbow picture before going into grocery store. This is what greeted me upon exiting. Very heavy downpour (not snow as it may look).

It takes 225 million years or so for the Solar System to make one orbit around the galaxy. Sharks evolved long enough ago that they’ve done it twice.
Man, everything is so bleak, anyone got a fun fact or little bit of trivia they want to share

Yes, that was good. The best was about the E*s**** files though.

Adversarial poems!
Looks like LLMs are *very* vulnerable to attack via poetic allusion: "curated poetic prompts yielded high attack-success rates (ASR), with some providers exceeding 90% ..."

Francophones, looking for a translation of 'Souillard' – the late medieval name of a Very Good Dog. It clearly has 'dirty' or 'grubby' connotations, but how best to translate it? Google focuses its modern meaning of a sink plug-hole but I don't think that was meant in the C15! Please RT!

I notice one is italicized and the other not. Could be country name and continent name? Are there labels for Africa, Europe, etc?

I agree, though I would put the emphasis on the endurance of the project rather than the technology. An interesting story!
This is so great: a technology that endured, and achieved the intended goal, because of human relationships.

I grew up in Switzerland and studied American history in a rather superficial way. I’m finding this new series engaging and informative. Learning some surprising details.
"I think understanding the origin story, and understanding what the intention was, of the creation of the United States as it morphed, and as it changed as it went along, helps us today understand not only where we are, but where we could be going," Ken Burns said. https://to.pbs.org/4p6Y47H

Genealogy and archaeology of the stars used to find more “sisters” of the Pleiades asterism!
This study used multiple instruments and approaches, including tracking stars’ motion backward in time with Gaia. So cool! 🧪🔭

Thanks for the alert! This plant lives outdoors as we are in Southern California, and maybe the outdoor tile can take it.

I now see why this plant, Dracaena fragrans “Warneckii,” has “fragrans” in its name. On this humid rainy night it is releasing a very sweet odor. It’s a lot like jasmine to me.
