A detailed digital composite image based on the 1947 historical photograph of geneticist Barbara McClintock. McClintock, with her characteristic short hair and round glasses, is seated at a microscope, using tweezers in a Petri dish. While based on the original photo distributed for her AAUW award, this image presents a significantly expanded and fictionalized laboratory environment. The simple wooden workbench is now densely populated with a vast, colorized collection of complex glassware, numerous amber-colored reagent bottles, intricate distillation columns, and botanical specimens relevant to maize cytogenetics, creating a rich, illustrative narrative of her "jumping gene" research context that was not present in the original photo. The expanded background shows complex vintage laboratory cabinetry. This image explicitly states it is a composite: a digital recreation where Seriously Scientific has taken the historical figure and placed them into an augmented, complex fictionalized environment. Based on original source from Smithsonian Institution Archives. Digital composite by Seriously Scientific.

Remembering Barbara McClintock on International Women's Day!
She discovered that genes aren't static, they can actually "jump" around on a chromosome.

Her discovery of transposons ("jumping genes") fundamentally changed how we understand evolution and the complexity of DNA! 🧬🌽

This is possibly the most disastrous thing Trump has tweeted. The demand for “unconditional surrender” from a country we are not yet at war with locks US policy in an unachievable dead end. I have FOUR chapters of my book devoted to that phase and how it prolonged WWII in Germany and Japan.

A warm, color portrait photograph of evolutionary biologist Lynn Margulis seated outdoors next to the textured trunk of a large tree. She is smiling brightly and directly at the camera with a joyful, approachable expression, her eyes sparkling with warmth and intelligence. She has short, curly graying hair, and wears small stud earrings. Her outfit is a patterned blouse or dress in deep purple with floral accents in beige, gold, and brown tones.

Evolutionary biologist Lynn Margulis' groundbreaking work revolutionized our understanding of life's origins and evolution, and how complex life began. She was born #OTD in 1938.

Older man, in running gear

[out running, young dude sees me approaching where he and his guys are gleefully having a snowball fight]:

Young dude: “yo guys hold up hold up let the gentleman by!”

Me: “It’s ok! I’m not that old!”

YD: “How old ARE you?”

Me: “61”

YD: “You’re doing ok!”

Bless.

When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Interesting. I'd be a little surprised if an Amazon car wasn't collecting our data. But I know part of their brief is to be simple and affordable, so maybe.

AI Death Machines. No Human Oversight. What Could Go Wrong? Pete Hegseth is trying to bully Anthropic out of objecting to “lethal autonomous weapons systems” and mass surveillance.

"It’s insane that “how much killing will we let the killer robots do on their own” is being hashed out as back-room handshakes between the military and its AI contractors. This seems like a matter of public policy if ever there was one. Have we got a legislature?"
