I've got Temu ADHD. I overpaid for this crap and it won't do the fun stuff in the ad. #ADHD

I'm old enough that I get a "repeat 3 words later" schtick from a nurse about every year. The nurse, reading from a script, said three words. I complained those were the same three words as last year. That felt good! I forgot this year's new three words. Maybe if I hear them I'll recognize them.

I was trying to write that I could not remember if a particle was a boson or a fermion. Autoincorrect changed boson to bison. Picture two bison colliding at near c in the Supercollider. I'm not cleaning it up.

This thread is an interlude to the series about "How Common is Life in the Universe?" There's a concept rattling around in my brain that I need to use in this discussion that needs some explanation. 🧪🧬🚀🦠 🧵 1/n Interlude

How Common Is Life in the Universe? NASA recently announced that: "A sample collected by NASA’s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life." They are called "potential biosignatures." 🧪🧬🚀🚀🦠 🧵 1/n

No matter what the Smithsonian said about slavery, it soft-pedaled how evil and horrific slavery was, if only because of a lack of room on the signs.

I'm working on a problem for fun & I don't like the answer I get. Assume the half-life of a radioactive element does not change with temperature or pressure. We have the same # of moles in a given volume of a radioactive element at the exact center of the Earth and in Pittsburgh. 🧪 1/2

Why didn't they call the recently discovered "hemifusome" cellular garbage collection organelle in humans a "Heftysome" after the garbage bag? 🧪🧬 #biology

We're watching "Walking with Dinosaurs" on PBS. It seems to be like the "Walking with X" from the '90s. Watch some adorable creature go through its life, get attached to the creature, and watch it die horribly. Understandable, but a bit depressing.

I was having blood glucose lows I didn't know about before the CGM. Cut my long-insulin. Ate part of a normal breakfast, BG went through the roof. Should have seen that coming. I feel stupid.

the white house's budget request for 2026 proposes a 47% cut in funding for nasa’s science mission directorate, which is DEVASTATING for space science. let’s fight back. sign this petition to show support and SPREAD THE WORD!!! let’s save nasa science. www.planetary.org/advocacy-act...

POTUS released a skinny FY 2026 budget, proposing to drastically cut funding for federal R&D across several agencies. AAAS urges Congress to reject the budget and to reaffirm their long-standing bipartisan support for S&T investments. Read the full statement: www.aaas.org/news/preside...

As we monitor the status of the still unobligated funds for FY25, AAAS CEO Sudip Parikh warns in a @nytimes.com article about the Presidential Budget Request for FY26. If enacted by Congress, “the consequences for the future of our nation will be catastrophic.” www.nytimes.com/live/2025/05...

“Are you worried?” That is always the first question. “Of course I am worried,” I respond. “The president of the United States considers me an enemy and has promised retribution. I would be an idiot not to be worried. But I am not going to give in. I will continue to fight.”

Don't worry guys. Even if the markets crash and burn, the Trump family, Elon, and Howard Lutnick will be fine! They have enough money to make it through.

I've been working on my SF novels about the search for life on Mars. The more I learn, the more the search looks like an astronaut using a small robotic excavator to dig three feet down and find living organisms in the sample. It's not a quest. The novel doesn't work. 🧵1/2

You must know by now that woke means science and truth and accurate facts. They prefer lies and misinformation. Also any women or dark skin people in charge, is also too woke. They only allow white men in charge. And yes, they're fucking nuts.

Blood Moon Total Eclipse. It's Pittsburgh, which usually means horrid seeing for astronomical events. There's a haze & some acrid pollution. I can only see a handful of stars. Around here, that's amazing. Cataract surgery: I can see this without glasses, for the first time in probably 58 years. 🧪🌌🥮

Bluetorial: Mentors: The long-serving dean Art Levine was a great leader, first at NIH, and then at the University of Pittsburgh He is a great mentor to me and others and a scientist's scientist (A long palate cleanser for today)

Also want to add—whether or not you are attending a rally, today is a great time to contact your representatives and let them know that the #StandUpForScience policy goals matter to you! 🧪

@ashleychristine.bsky.social I don't know if you'll see this. They found calcium deposits on a spit on my wife's mammogram. Statistically nothing, but they gave a list of increasingly scary next steps. I'm a former paramedic who got all the weird/potentially lethal calls. I learned to think 🧵

@lostmydeuteron.bsky.social There's a nucleotide other than ACTG and U that's used in biochemistry. I'm drawing a blank on it and can't even find it with Google. Do you happen to remember what it is? Thanks for whatever you can think of.

Nancy's been asking me about the formation of planets. I keep getting weird mental images of distillation columns, filtration columns, and Continuously Stirred Tank Reactors (CSTRs) with gravity tanks, iffy density stirring, and something randomly throws junk in the CSTRs. Is that ~right? 🌌🧪

@chriscmooney.bsky.social Welcome! I remember reading your book "The Republican War on Science" in New Orleans helping to clean up after Katrina! Glad to have you here!

Black excellence: Twice as qualified, half as respected, and still passed over or labeled as a ‘DEI hire.’ Black folks have always known this because we’ve seen it happen to our own family members. I know I have.

Osiris Rex Report: "We detected amino acids (including 14 of the 20 used in terrestrial biology), amines, formaldehyde, carboxylic acids, polycyclic aromatic hydrocarbons and N-heterocycles (including all five nucleobases found in DNA and RNA), along with ~10,000 N-bearing chemical species." 🧪🧬🧵1/3

TOMORROW! 🔭🧪👩‍🔬 If you plan to attend remotely, you'll receive a Zoom webinar link to the email with which you registered. Otherwise, we'll see you on the University of Chicago campus for an evening celebrating astronomy and the scientists that do it :)

The Osiris Rex team reports that samples from Benni contain racemic versions of 14 of 20 amino acids and all five bases from nucleotides in life on Earth. Did they find amino acids or nucleotide bases that are not found on Earth? 🧪🧬🌌

Correlation is not causation, but there's a lot of correlation here. PEPFAR began in 2003 near the peak of world AIDs deaths. Today 20M people receive HIV treatment through PEPFAR funding. That's almost 2/3 of people treated in the world. Call your Congress people and get PEPFAR back.

Linda pioneered the field of regional climate modeling, led the National Academies review of the US National Climate Assessment, and inspired hundreds of us to more rigorous science in support of climate services. She will be sorely missed. 💔

Hey, friends— Things are REALLY rough for political cartoonists right now. Their traditional clients are refusing to run their work. New clients can’t afford to pay them. A lot of political cartoonists are subsisting off patreons. If you share a political cartoon, please credit the cartoonist.

@kyraana.bsky.social Welcome to BlueSky! I've been a bit nerdy over here, but I'm glad to have you!

The students in the psychology class were given a one page personality test. The filled it out, signed it, put it in an envelope and handed it in. The next day, the students received an envelope with their names on it. Inside, was a piece of paper with a paragraph in small type. 🧪1/3

My latest for @the-revelator.bsky.social : I spoke to experts about some of the most threatened species in US waters, the threats they face, the policy solutions they need to recover, and why the second Trump administration is likely to be a disaster for them. Please read and share. 🧪🦑🌎

Ms. Harris did stand up--repeatedly--in her campaign. It's time for White men and women to stand up against injustice.

Excellent video! 🧪🌡️
