TIL about the "bomb pulse" - when carbon-14 in the earth atmosphere doubled as a result of nuclear bombs and tests in the 1940s, 50s and 60s.
This increase in carbon-14 allows researchers to date human and organic samples precisely, sometimes all the way down to the month. Using the #bombpulse to accurately date samples will end when carbon-14 levels return to baseline.
Around the year 2030 the bomb pulse will die out. Every organism born after this will not bear detectable bomb pulse traces and their cells cannot be dated in this way.
oh nice 😯👏 #glass#3Dprinting "Research into artisan glass-blowing on a robotic platform has produced a technique that uses a laser to heat the surface of a glass rod so it can be deformed to create 3D shapes. It is able to create the transparent solid structures needed in optical, microfluidic, and photonic devices. The method can deposit glass at 15 cubic millimetres per second." https://spectrum.ieee.org/glass-3d-printing

"The "AI Scientist" was created to conduct scientific research autonomously by using AI language models. During testing, the system unexpectedly began to attempt to modify its own experiment code to extend the time it had to work on a problem. The experiment shows why it is important to not let an AI system run autonomously in a system that isn't isolated from the world."
"Aldous #Huxley reflects on #criticism and why he does not read reviews of his own work - "They’ve never had any effect on me, for the simple reason that I’ve never read them. I’ve never made a point of writing for any particular person or audience; I’ve simply tried to do the best job I could and let it go at that. The critics don’t interest me because they’re concerned with what’s past and done, while I’m concerned with what comes next."
Photography from the antipodes. Based in #Dharawal #Sydney the land of thunder and marsupials. Not very good at introductions. Really good at walking. Fond of oceans. Civility. Tests code for a living. Own pics fresh daily. #a11y #lovesclouds next life a #Trill🤞🖖 #fortheloveofit
