Trump’s America.

Nightmare.

A joke for the history buffs.

Danish Parliament Deputy Speaker Lars-Christian Brask: "If I could come with some advice, it would be for the Senate & House to start to take control of political power in America because with this erratic & mad behaviour, you have to ask the question, is the President capable of running the US?"

Ain’t having much luck with this Northern Lights thing. The one time I didn’t go out (bc my useless app suggested not to) people nearby posted cool pics. The three times I did go out, I’ve mostly seen nothing but dull sky. 🧪

The Nobel Peace Prize committee may have to give itself the Nobel Peace Prize for not giving Trump the Nobel Peace Prize.

Pew Research Institute (2023): • Red State Texas has about 2.1 million undocumented immigrants • Red State Florida has 1.6 M undocumented immigrants • Blue State Minnesota has 130,000. And yet only Minnesota is being occupied by masked thugs over "immigration." It's *not* about immigration.

Do you appreciate someone from decades ago? It’s not always too late to thank them! 🧵 🧪 #chemsky #chemchat

Is it fairly common to do prep HPLC separations using only MS signals to decide when to collect product? For compounds with poor absorbance? E.g., amino acids. 🧪 #chemsky #chemchat Max Jr is curious too.

New research shows exercise is as effective as medication at reducing symptoms of depression. And you don't need to run a marathon to see benefits. So how much is enough?

AI tells me: Mars's current atmosphere shows ¹³C depletion in its CO₂, meaning it has less ¹³C compared to ¹²C than Earth's atmosphere does, explained by the lighter ¹³C being less prone to escape during atmospheric loss over time.” 🧐🤓🥸 🧪 #chemsky #chemchat

Smart/birder friends, why did all these little birds fly into my neighbor’s bush and get all chirpy TODAY? Near Cincinnati Ohio. 🧪

I love how in the movies (esp old movies) the aliens have some freaky evil technology that is nothing but a black box to us, yet in about 36 hours we (always an older white man) have a fix for it. 🧪 #chemsky #chemchat

Ex-Minnesota Governor Jesse Ventura: “We’re a 3rd world country now. I know. I’ve been to ‘em. I spent 17 months in SE Asia while the draft dodger was playing golf… that’s what happens in a dictatorship. In comes the military. That’s what’s happening here.” 🇺🇸

I’m old enough to remember when “America First” meant staying out of foreign wars & no govt overreach & protecting citizens & respecting the sanctity of life They have no values. Stop pretending it’s a political party & not a cult whose leader will never ever be wrong They will murder you.

Dream: some billionaire (trillionaire?) opens a gigantic laboratory where regular (non-superstar) scientists could work on their pet idea(s) for a year or two, to see if it’s feasible. Imagine the discoveries that would happen, the collaborations formed. 🧪 #chemsky #chemchat Also: Max Jr.

I know we see this crazy stuff a lot, but this was at the science section of a museum! Sheesh. I sent them a message, begging them to find a chemist to fix it. 🧪 #chemsky #chemchat

2025 brought us a new Pope ⛪ This was one of my most popular infographics this year, explaining how the Papal Conclave produces the black and white smoke used to signal the results of Pope selection votes: www.compoundchem.com/2025/05/08/p... #ChemSky 🧪

On Christmas Eve 1968, in Lunar orbit, the Apollo 8 crew took this photo: “Earthrise." I'll never forget how inspiring the Apollo missions were to my brother and me as kids. They showed us what our country and humanity can accomplish when we work together toward a common goal.

Wot. 🧪 #chemsky #chemchat

Found this little guy in our bathroom. I guess he is a “bold jumping spider.” some people keep them as pets.

Max Jr found a sun puddle.

Increase in productivity since 1979: 87% Increase in hourly pay since 1979: 32% Just so happens that ~25% of workers were unionized in 1979. Today? 10%. As unions declined, the super-rich have taken a larger share of wealth generated by labor. We must build back union power.

Hard to resist a little plod-jog in gently falling snow.

Does anyone know why only this single ester forms from Glu-HCl? Does some coordination “protect” the other acid? 🧪 #chemsky #chemchat

This iconic Fabian Todorovic cartoon is still one of the best I’ve seen at illustrating the remarkable amount of space we surrender to cars, leaving little space left for everyone and everything else. The text added later makes the bonus point that many drivers still manage to complain about it.

Topo Trail Run. East Fork State Park, Ohio. Still running shorter races while trying to build back after 18 months of injuries. Not to mention old age and some lazy training. But, still enjoying it.

Rule of thumb for synthetic organic chemists: The large scale prep is never as clean as that small scale test you did first. 🧪 #chemsky #chemchat Max Jr agrees.

After being told by a female relative that I have TDS it was hard not to respond, “quiet piggy.” But, I couldn’t go there.

This is actually quite brilliant, up to and including the final sentence 🔥

Always satisfying when a thick yellow oil puffs up to a white solid under vacuum. Although it did eventually threaten to leave the flask entirely. 🧪 #chemsky #chemchat

I was diagnosed with #HIV in 1998, when I was 30. Many of my friends had died of AIDS. I did not expect to live to 50. I’m 58 now. HIV treatment works. Treatment also makes it impossible for me to pass HIV on during sex. Ensure HIV treatment for all. End HIV stigma. #WorldAIDSDay

No one will stop me from defending our freedoms.

Interesting

#chemchat #chemsky I need your recommendation for a very high boiling point solvent that can be used at 300C. Ph2O is not high enough (it goes to around 250C). Cannot be protic, cannot have amines. It doesn't need to be a liquid at room temp. Ideas? Cc @adrianlorenzana.ca

One nice thing about electronic notebooks is that you can add pics, instead of drawing TLC plates or taping traces/spectra. #chemdraw #chemchat 🧪

I am grateful for @repshontelbrown.bsky.social

Is IR spectroscopy dead? Is anyone routinely using it? Can it be used to indicate purity? I figure I’m just clueless here - my company goes with other methods (e.g., NMR, HPLC-GC, KF, MP/BP, titration, ion chromatography) to access structure/purity. #chemsky #chemchat Max Jr also wants to know.

I’m confused. What is the difference between #chemsky and #chemchat? When do I use one versus using the other?

Assuming this is real, folks with money go here, eat, and leave a tip.

Election Night wasn’t just a Blue Wave — it was a Blue Tsunami. And the color that made it all possible was Black.

It’s that time of year.

Anyone here with practical knowledge about making phenylalanine from phenylpyruvate using phenylalanine dehydrogenase (or similar)? #chemsky 🧪

I did my undergrad here. Excellent department. Good people. Also Iowa City is a particularly cool place. Forget your typical idea of “Iowa” as a state - IC has lots going on.

Ozempic, MRI machines and flat screen televisions all emerged out of fundamental research decades earlier — the very types of study being slashed by the US government go.nature.com/47hn0n5
