In early 2025, wildfires spread through Los Angeles, destroying thousands of homes and businesses. Residents turned to online maps for rapid air quality updates. A few months after the fires, researchers looked at the data that went into those maps from federal monitoring stations, low-cost sensors, and satellites. They highlight the importance of combining these tools to convey simple, easily accessible information to the public.

This grid of pastel- and candy-colored squares is not a personal color analysis swatch. (But could it be a True Spring?) It’s actually a set of tiny sensors that identify and measure concentrations of toxic gases, including the nerve agent chlorosarin, in less than five minutes.

Nanoparticles — spheres so small that they’re undetectable by the human eye — could be a potential therapeutic for rheumatoid arthritis. Researchers report in ACS Central Science that they’ve developed new nanoparticles that could slow disease progression and prevent flares, according to initial tests on human blood and animal trials.

It's hard to believe summer break is winding down (or has already ended for some of us!), classes are beginning again, and a new group of students is about to dive in to chemistry for the first time. We're holding on to those final few weeks of summer with this throwback to the U.S. National Chemistry Olympiad Study Camp days. These students had a lot to say about their favorite chemical elements, study snacks, and science-y word. What's your favorite element? What about your favorite science word? Let us know in the comments! ⤵️ #BackToSchool #ThrowbackThursday

After years of discussions, 107 nations agree to establish the Intergovernmental Science-Policy Panel on Chemicals, Waste and Pollution: https://lnkd.in/ebXH-Hkk

We asked a few ACS interns what they learned this summer. Here is what they had to say. #NationalInternDay #InternDay

C&EN’s Talented 12 turned 10 this year. Celebrate a decade of rising stars in chemistry at the #ACSFall2025 symposium, where we spotlight early-career researchers driving the field forward. Don’t miss the opening keynote from Neil Garg, Distinguished Professor at UCLA and leader in organic synthesis and science education. Engage with us onsite and pick up a limited-edition Talented 12 T-shirt in honor of the anniversary. RSVP here: https://lnkd.in/ebkVqXp3 #ACSFall2025 #CENT12 #ChemPowered

The future of #chemistry depends on how we prepare today’s students. What skills do you think should be top of mind? Share your perspective and look for more at our upcoming Future of Chemistry Degrees panel at #ACSFall2025.

For almost 70 years, scientists have been puzzling over this mystery goo from an ancient Greek shrine near Pompeii. Initially, archeologists thought that it must be really old honey, but data supporting that conclusion haven’t been collected until now. Researchers publishing in the Journal of the American Chemical Society analyzed the ancient residue using several modern analytical techniques. They’ve identified it as honey, even if it’s mixed with other plant or animal products. As for whether you can eat this 2,500-year-old honey, well, more research might be needed. Image 1: The bronze jar on display at the Ashmolean Museum which contained a mysterious substance (shown in the foreground) that is very likely ancient honey. Image 2: Likely what 2,500-year-old honey looks like, according to new tests using modern techniques. Learn more about this study: https://brnw.ch/21wUxKG
