ICYMI: Update on the helium scramble caused by the war in Iran. Asia is shopping for North American helium, supplies are getting shaky in Europe, and GCMS is hit harder for now than NMR. cen.acs.org/business/spe... #helium #chemistry #NMR #GCMS #Iran #news

"Although some may find joy in the music of the digestive tract, there are more pleasing sounds you can make by forcing gas through a constrained space. Look no further than the venerable pipe organ." #chemsky 🧪

Ultrasound-activated nanoparticles breach bacterial biofilms: When hit with low-frequency ultrasound, the nanoparticles release antibiotics deep inside bacterial communities. #chemsky 🧪

Diagnosing bacterial infections deep inside your tissues can be highly invasive, requiring procedures such as tissue biopsies or blood cultures. Now researchers have made strides toward solving this issue. #chemsky 🧪

Biologists would love to know exactly what happens inside a cell, but measuring every cellular process simultaneously is impossible. That’s why they turn to simulations, like this one, which tracks how a bacterial cell divides into two: cen.acs.org/physical-che... #CENChemPics #chemsky 🧪

How do test subjects feel about wearing a bonafide fart-rate monitor? @brantleyhall.bsky.social says: “At some point, Fitbit was weird, right? We got over it.” Read about it in C&EN: cen.acs.org/biological-c... @cenmag.bsky.social

In editing this script, i got to revisit what is perhaps my favorite piece of science journalism: www.fastcompany.com/3008346/deep...

One by one, hospitals are abandoning trans kids as they preemptively cave to HHS threats over Medicaid/Medicare funding. They ought to consider the terrible message walking away from some kids sends about their dedication to caring for all of them. My latest @opinion.bloomberg.com (🎁 link):

Gotta love a new big ol’ sheet of carbon 😙👌

Journalists lost a lot of public trust when politicians turned the term “fake news” (a term journalists came up with!) into a weapon. Similar things have been happening in the language of science. I got to spew a bit about it in @cenmag.bsky.social cen.acs.org/education/sc...

As always @markpeplow.bsky.social's stories spark curiosity, but this one about cuprocene also sparked debate: sandwich or hot dog? Well, cuprocene is definitively a sandwich. If you're looking for something to argue about, this californium complex seems more hot-doggish: cen.acs.org/physical-che...

Hope that one day my capable colleagues will have a say in the direction that C&EN is headed. Here we go …

I've been at C&EN for over four years and I can genuinely say our staff is some of the most thoughtful, dedicated people I've ever worked with. With @cenguild.bsky.social, we can make sure we're all supported in our effort to keep putting out our unique brand of high-quality science journalism!

In the age of gpt, i appreciate this edit more than i used to. Feels quaint but necessary. m.youtube.com/watch?v=Rt0d...

I think it says a lot about the current moment that we chose molecule that is surprisingly holding itself together despite a thermodynamic incentive to break down...

Final round of the bracket closes on Sunday. VOTE!

fellas try voting on a color photograph next year

I don’t know who needs to hear this…so I’m not going to say it until I have better info

It's that time again: C&EN's molecule of the year poll is now open! Vote for your favorite molecule of 2025: cen.acs.org/synthesis/Mo... #chemsky 🧪

I know #chemsky was dabbling in the #mincup @mineralcup.bsky.social . Now we have our own bracket. Vote for your favorite chempics!

We're getting to the end of 2025, so why not: We made a bracket. VOTE on our best science photos. These scientists ... man, are they doin' some wild stuff! #CENChempics @cenmag.bsky.social cen.acs.org/education/sc...

I love a good complex natural product. This one has two α-tropolones, 10 asymmetric stereocenters, and a a labile hemiketal. After a longstanding effort, chemists in Seth Herzon's lab have made (–)-gukulenin A. My latest for @cenmag.bsky.social cen.acs.org/synthesis/me...

It’s pretty exciting that we might see big auroral displays in Maryland tomorrow night! Last fall, I couldn’t believe how purple the sky got… anyway, if you’re interested in how CMEs and solar flares form, check out the story I wrote last month for C&EN! 🌌☀️ cen.acs.org/physical-che...

In 2024, Belén González-Gaya tagged along on a tourist cruise to get to Antarctica and study contaminants of emerging concern. Among the chemicals she found were a human metabolite of nicotine, and degradation products of an ingredient in sunscreen. cen.acs.org/environment/... #chemsky 🧪

Yes, there's lead in protein powders. No, there's no known safe level. But, exposure to trace amounts is inevitable, especially since plants naturally take up lead from the environment. And, people disagree on standards for manufacturers. Latest @cenmag.bsky.social: cen.acs.org/food/food-in...

Years ago, when I began my journey in STEM, I never would have imagined chemists with disabilities like myself would ever been seen as "trailblazers". Now, I am so grateful that the @acs.org and @cenmag.bsky.social have celebrated chemists with various disabilities in this years Trailblazers issue!

I admit that when i started working on this project with @kvasquez.bsky.social, i didn’t think i knew any chemists with disabilities 🧵1/ cen.acs.org/people/profi... @cenmag.bsky.social

Did you know Dorothy Hodgkin had a disability? I did not! This is a little taster before @cenmag.bsky.social drops our big Trailblazers package featuring chemists with disabilities in Sept: cen.acs.org/careers/dive...

Researchers have developed a spray that can keep fungi at bay. The nontoxic solution forms an extremely hydrophobic surface coating that makes it harder for fungi to latch on to a surface and kills them if they do take root. cen.acs.org/materials/co... #chemsky 🧪
