This looks like a truly stellar cohort of fellows--I'm super excited to see what they accomplish!

EPA says burning plastic fumes are fine, actually, don't worry about it:

Chemists caught up in travel anxiety at ACS Spring 2026 Long security wait times and the presence of ICE agents at the Atlanta airport were the talk of the meeting between sessions

Travel nightmares and 🧊 in Atlanta affected many folks at last week's ACS meeting.

How do you study microplastics when they’re everywhere? Microplastics are everywhere, which makes studying them all the more difficult. Labs are doing all they can to be plastic-free but have few common protocols

I was quietly tickled to read the URL "how-study-microplastics-when-everywhere." Then, I was fascinated to hear how much WORK it is to study microplastics in a controlled way. Positive air pressure, 100% cotton lab coats, this story has it all.

@fmorningstar.bsky.social and I tried a synthetic ice rink so you don't have to! The company that made it says it could be the future of ice sports. I'm not convinced.

A screenshot of a news article titled “Editorial: Can we future-proof the language of chemistry?” The opening art is a television’s showing the dictionary entry of the term “global warming”

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...

Inside the push to make ice rinks sustainable Rinks use energy, water, and refrigerants, and they create microplastics. People are trying to reduce this footprint

Ice rinks are energy-and water intensive to maintain. Researchers are considering ways to make them more sustainable, but there are quite a few trade-offs.

Can recycled lab gloves capture carbon dioxide? Chemists upcycle nitrile rubber into carbon-sequestering polyamines

As you may have heard we've got both a climate crisis and a plastic waste crisis on our hands. My latest news story for @cenmag.bsky.social is about researchers trying to tackle both problems at once by upcycling nitrile rubber gloves to capture carbon dioxide:

I started my education in biology just as CRSIPR's gene editing potential was discovered. Now, 14 years later, sitting down with Jennifer Doudna 1-on-1 to write this profile is a highlight of my career.

The Schrödinger equation turns 100. Century-old quantum formulation continues to be one of chemistry’s most-used tools. by Ananya Palivela. A collage of images of Schrödinger, his 100-year-old paper and his equation.

One hundred years ago, Erwin Schrödinger came up with an equation that rewrote the rules of matter. The equation is expected to continue shaping the future of chemistry by playing a role in quantum computing and machine learning algorithms for chemical design. cen.acs.org/physical-che...

How did chemists identify the poison that killed Alexei Navalny? Epibatidine is used in research but is not part of typical toxicology panels

One fun part about my job is that sometimes my coworkers will DM me things like "What is this starting molecule called and also how hard does this frog toxin synthesis look" and in return I can ask them silly questions about biology.

MAHA’s next target: metals in vaccine ingredients Officials are going after metal-containing ingredients, including aluminum adjuvants. Here’s why vaccines need them

Aluminum learns to ride a redox cycle Main-group metal performs like a transition-metal catalyst to build aromatics from alkynes

Researchers have devised an aluminum complex that undergoes a full catalytic cycle. The metal switches between two different oxidation states to assemble substituted benzene rings from alkynes. cen.acs.org/synthesis/ca...
