Beautiful work, congratulations to you and your team!

Excited to share our latest @nature.com: How does naloxone (Narcan) stop an opioid overdose? We determined the first GDP-bound μ-opioid receptor–G protein structures and found naloxone traps a novel "latent” state, preventing GDP release and G protein activation.💊🧪 🧵👇 www.nature.com/articles/s41...

Panel 1: Jonathan Kunz and Elizabeth Pich sit on a couch in a therapist's office. Elizabeth says, "People on the internet keep telling us we need therapy." Panel 2: The therapist asks, "What do you do?" Jonathan responds, "We make webcomics." Panel 3: The therapist, looking at a tablet, says, "Aww, these are funny," as she scrolls through their webcomics. Panel 4: The therapist looks up from the tablet with a concerned expression and says, "But I'm afraid you're beyond help."

A 107-Year-Old Irish Farmer Reflects on the Changes He’s Seen During His Life (1965) Talk to a clear-headed 107-year-old today, and you could expect to hear stories of adolescence in the Great Depression, or — if you're lucky — the Jazz Age seen through a child's eyes.

How politics works

From the new Private Eye, out now.

3-panel comic. (1) [two people laying on the grass on a curved surface, oriented vertically] PERSON 1: I don’t like being stuck to this orb, but I guess falling off would be worse. (2) [the surface has rotated slightly] PERSON 2: I wouldn’t mind if it pulled a little less hard, though. I have places to be. I shouldn’t just lie around in the grass. (3) [the surface has rotated a little further] PERSON 1: Maybe the pull will weaken if you wait a little longer. PERSON 2: Good idea. I’ll give it another five minutes.

That’s a wrap on ECM35! But it doesn’t end here: visit our booth one last time for IUCr 2026 highlights, sneak peek previews, and ways to stay engaged all the way to Calgary.

See you there!

I’m an award-winning mathematician. Trump just cut my funding. The “Mozart of Math” tried to stay out of politics. Then it came for his research.

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...

Morphine analogues kill pain with fewer negative side effects Redesign of the potent painkiller's core prevents breathing suppression and reduces addiction-related behaviours in mice

A simple skeletal edit produces a morphine analogue that kills pain but has fewer negative side effects.

Enough of the billionaires and their big tech. ‘Frugal tech’ will build us all a better world | Eleanor Drage Titans like Musk would love us to believe innovation means top-down solutions that only enrich the wealthy. In fact, we all have the power, says Eleanor Drage, research fellow at Cambridge University

This is well worth a read.
Some glad someone is championing that most impactful technology is cheap and easily obtainable.

I was explaining to my Ukrainian colleague the phrase ‘There’s no such thing as a free lunch’. She told me the equivalent in Ukrainian is ‘The only free cheese is in the mousetrap’ - which is so much better

Getting good at human tasks 'What do you mean you had to lock the NMR with an oscilloscope and shim the magnet by hand?'

Just as scientists no longer have to spend time shimming NMR magnets or inserting samples by hand, thanks to autoshim routines and autosamplers, one day we will look back at the things we do by hand now and marvel at how far we've come. #ChemSky #ScienceSky

Wonderful event, great to see and interact with so many amazing talented technicians and the rest of the @ucl.ac.uk community.
Also gained a new appreciation for how nice a setting UCL East has in the Olympic park.

Part one of today's UCL Open Day. Big crowds. very busy. We have six demonstration stations to talk about ocean acidification and carbon dioxide, fluorescence, magnetism and superconductivity, use of microwaves in synthesis, and the smells of organic compounds.
Fun for all the family. #chemistry
