Reported in @science.org, lithium pentasilacyclopentadienyl complexes. These silicon analogues of the cyclopentadienyl ligand have a non-planar 5-membered ring and further characterisation shows evidence of aromaticity. 🔗 CSD Entry EXOMUD: dx.doi.org/10.5517/ccdc... #FeaturedStructureFriday

This is niche but every time I visit London and ride the underground, I have “And you’re giving a treat, penny ice and cold meat, to a party of friends and relations: they’re a ravenous horde and they all came on board at Sloane Square and South Kensington stations” running through my head

Can astronomical imaging be more sensitive, with no additional observations? Guo et al. apply machine learning to the co-addition (stacking) of multiple exposures. For stacks of 8 JWST NIRCam exposures, the detection limit improves by 1 magnitude. ☄️🔭 #astrocode www.science.org/doi/10.1126/...

Good morning team! Here's a professional society standing up!

Not really my lane but something super weird about The Olympics is how everyone watching and commenting treats it like a show. It’s not really fair for people who do the best sports thing and are barely adults to also have to be amazing actors. If you lose you should be allowed to cope privately.

Still had to do this though

Roses are red. Valentine’s Day is bad. Married couples ignore it and it makes lonely people sad.

C, low brow Reese’s isn’t improved by high brow treatment

President Donald J. Trump and Environmental Protection Agency head Lee Zeldin announced that the EPA has finalized rescinding the endangerment finding. This is the legal basis for regulating greenhouse gas emissions under the US Clean Air Act. cen.acs.org/environment/... #chemsky 🧪

NSF's graduate research fellowship (GRF) program is designed to teach aspiring scientists how to write a winning grant proposal. So why are so many applicants being denied that learning experience? www.science.org/content/arti...

Exciting chemsky work out First Release in @science.org from @gracegdhan.bsky.social and collaborators, scrunching up pyrimidones so tight with UV light that the strain release can boil water! www.science.org/doi/10.1126/...

By probing the compositions of atmospheric aerosols down to 3 nanometers during a heat wave, researchers discovered an essential role of carboxylic acids in new particle formation. Learn more: https://scim.ag/4rGT5vS

Anyway if you appreciate my posting, please do me a favor and preorder my book and if you cannot afford to, put in a request to your local library, which is a great way to keep books alive for generations I esp. appreciate support for Loyalty which is working hard to support local organizing in DC

kind of funny that an olympian said they are here to represent "compassion, respect, and love for others" and some people automatically knew that was a statement against them

One more comment on the Post debacle: this hurts journalism broadly. Good journalists will go do something else. The rest will be fighting for fewer jobs and everyone will earn less. Fewer people will take up the career. The damage done is to the ecosystem, as well as the paper.

Jeff Bezos’s wealth has increased an average of $70 million every day of 2026, meaning that he could have offset The Post’s losses with what he’s made since Monday.

Enough ice has melted off the solar panels that we're finally generating more power than we're using!!!

What can you even say about shredding the WaPo staff? Richest guy ever won't backstop news from the capital city. And the craziest part is if they'd bought Wordle it probably would have made a tangible difference. That's where we are. It'll be an essay question in 100 years.

Other thing about the new iOS is it now always says I have one unread email when I don’t, and if someone tried to come up with a trivial thing that would drive me completely bananas, they couldn’t have done much better….

Good night to all the trees and the trees only. Hope your Rosh Hashanah was a meaningful one and your coming year is a great one!

House Republicans released a discussion draft (PDF) of a bill to update the Toxic Substances Control Act (TSCA), the primary oversight law for industrial chemicals in the US. cen.acs.org/policy/chemi... #chemsky 🧪

The thing is on the one hand it’s very frustrating they’re closing school again but on the other hand every time I’ve tried to walk on a sidewalk for the past week I’ve fallen down, so it’s probably the right call. Just a ridiculously hard kind of snow to clear.

IMO Molière should be mandatory in Med Chem 😅

Also I wrote a final paper where I argued comedies are actually tragic and used the word neanmoins a lot and that’s why it was probably good that I majored in chemistry😭

Not doing the 5 courses thing because I’m opposed to memes that haven’t made me laugh yet but I took a French drama class freshman year with 2 other people in it where we read Molière outside on sunny days and it was probably my favorite course.

Chocolate cake. I like chocolate! I like cake! But somehow chocolate cake is almost always the worst cake flavor option.

A look at the new MOSAIC paper on an LLM-based system to try to help with predicting synthetic chemical lab procedures:

It is somehow still January

I’m reduced to busting up rock solid snow with a sledge hammer—how’s your day going?

The US government lost more than 10,000 STEM PhDs last year, according to an analysis by Science of newly released OPM data, with 11 departures for every hire. And many OPM calls "voluntary" separations were probably pushed. www.science.org/content/arti...

extremely wholesome scenes in my neighborhood (I bet in yours too): kids building snow forts, neighbors freeing each others' cars and sidewalks from ice. nice to get the opposite of the doomscroll in

Alex Pretti’s coworkers take a moment of silence this morning

Looking for sources for a @nature.com story about how researchers are coping in the midst of current events: If you're a PhD or other academic who's struggling to focus with everything that's happening in the world and would like to be interviewed for this story, please get in touch ASAP!

Most of today's quantum computers rely on qubits with Josephson junctions that work for now but likely won't scale as needed for applications. cen.acs.org/materials/el... #chemsky 🧪

Because I want them to be worldly and cultured, I'm teaching my kids to make French toast, instead. Exotic.

10yo currently upset that because of tomorrow’s forecast, school might not actually be canceled on *Tuesday*😭

Like I was saying a little while ago. These have just enough chocolate chips. Also go great with this rye-finished hickory syrup from Mount Vernon

You can't spell "Washington" without "Hating Snow."

In @science.org for chemsky this week, Dave MacMillan’s group use cobalt catalysis to fuse saturated and aromatic rings www.science.org/doi/10.1126/...

This is a terrific and important story about how hard it’s going to be to put Humpty Dumpty back together again in US academic science, even if funding levels ultimately get restored. Features some good quotes from @chemjobber.bsky.social chemsky #chemchat

Public trust in science and technology is a serious, growing problem, especially now. Instead of trying to solve it with better communication, we should adopt a more inclusive approach to innovation that takes low-tech, incremental, and system-wide solutions seriously. My new piece @science.org 👇🏽🧵
