Quiz: C&EN’s periodic table challenge Can you remember all 118 elements in the periodic table without looking at the answers?

I named 28/118 elements in the Periodic Table Minute Challenge on C&EN! Can you beat my score? cen.acs.org/education/sc...

muse-scripts for this month courtesy of yours truly! these protein names have fascinated me since high school so it was a total blast to investigate them : )

Music inspires proteins and scientists alike A symphony of proteins and an orchestra of scientists

Aromatic 5-silicon rings synthesized at last 2 groups working independently construct the same long-sought compound via different routes

Move over, cyclopentadiene anion. Working independently, Takeaki Iwamoto's group and David Scheschkewitz's group synthesized a five-membered aromatic silicon ring. My latest for @cenmag.bsky.social

Thanks for sharing! ❤️ I'm saving this to share with my Chem 1 students tomorrow.

The chemistry behind the NFL’s highlight-reel catches Football players in the NFL use gloves coated with tacky silicone to help them grip the ball

I'll admit it. I don't follow football. But @maxhenrybarnhart.bsky.social's story about the gloves football players wear for @cenmag.bsky.social is positively gripping.

Matt's team did a great job. It would be great for the private (pharma) and public (academic) sectors to share similar (unpublished studies). These data exist but unfortunately languish on shelves because most want to publish positive outcomes.

How to put drug leads forgotten in the freezer back to work Open science advocates create a guide to sharing medicinal molecule collections

Many years ago when I was a graduate student doing medchem, compounds would languish in our freezers after testing. Chemists in Matthew Todd's group are looking to make better use of such molecules. My latest for @cenmag.bsky.social.

What is the toxin in Nestlé’s recalled infant formula? Cereulide contamination has led the food giant to pull products from 50 countries

Mike McCoy and I wrote this explainer for @cenmag.bsky.social about cereulide, the toxic compound that recently led Nestle to recall infant formula in 50 countries. The molecule's resilience is terrifying.

At MAHA Summit, the NIH head pushes for research that risks failure And 4 other takeaways for life scientists from the ‘off-the-record’ Make America Healthy Again conference

So, remember that MAHA summit 2 weeks ago that @statnews.com broke the news of and @maxkozlov.bsky.social somehow got into for Nature, even though it was closed to the press?

The organizers posted the entire 6.5-hour conference proceedings to YouTube last week.

Proteins plucked from the pages of Renaissance recipes Analyses of German medical manuals from 1531 reveal what ingredients those who handled the books used

Do you have recipe books with annotations and stains on the most popular pages? Me too, and so does the University of Manchester. Except their recipe books are medieval medical manuals.
