A ChemScrapes illustration showing how big a mole of eggs would be. The size would be roughly that of 5 moons. The image shows two people staring up at 5 moons. The person on the left asks, "Mum, what are the moons made from?." The person on the right says, "A mole of eggs, Dear."

Happy Mole Day, everyone! 10 to the 23 is a biiiiig number. Here are some incredible drawings from @chemscrapes.bsky.social illustrating the bigness of moles and the smallness of atoms and molecules.

Over the weekend ICE abducted an NIH contractor when he showed up to a courthouse for his green card hearing. He is documented. His wife is a citizen.

He is also member of the skeleton crew of animal care staff that works through a shutdown, to ensure the health and wellbeing of research animals.

Why some federal workers aren't scared by the threat of shutdown layoffs Some federal workers support the government shutdown, even as President Trump threatens to use this moment to lay off employees and cut funding to programs.

@jenna-m-norton.bsky.social β€œEvery awful thing that would happen in a shutdown...is already happening.” This isn’t about partisanship. It’s about stopping the erosion of our public services. It’s time to protect the programs that serve our communities and stand up to authoritarianism. #StopTheScam

Former CDC director weighs in on leadership shakeup The White House says CDC Director Susan Monarez was fired because she was not aligned with President Trump's mission to make America healthy again. What does the exodus mean for the agency?

"I never thought I would see the day when I couldn't rely on the CDC website for fact-based information with transparency about how it got there, what it's recommending and why."

Former CDC director and author of "The Formula of Better Health," Dr. Tom Frieden, on @npr.org's All Things Considered:
