NSF email to GRFP applicants from TODAY: you MUST submit official academic transcripts with your most recent academic status!
First year PhDs often don't get these until the end of this semester.
No clarification opportunity because of government shutdown.
Application deadline is next week.

Not *one* mention of Plateau-Rayleigh in this article.
The Federal Reserve faces a blind spot: with the government shutdown halting release of economic data, policymakers must rely on indirect indicators.
But the Fed still has a range of private, internal and public data to help it read the pulse of the economy.

Fed struggles to assess state of US economy as government shutdown shuts off key data
Even in the best of times, the Fed has a tough time interpreting the data and deciding how best to guide the US economy.

Without describing the experiment (soon!), please just enjoy with me a case where a simple model meets the data this well. Oh man. Math, I tell you. Good stuff.

Out today in Phys. Rev. Fluids, our 'Arrested development and traveling waves of active suspensions in nematic liquid crystals'. The bend instability in active suspensions pairs off against bending resistance in LCs to tell quite a story! 1/20

This is a remarkable paper, or probably many papers squeezed into one. I cannot help but be amused that sperm hyperactivation (a swimming state with large amplitude, asymmetric flagellar beating) can be triggered by... caffeine.
‼️Excited to share our latest work:
www.biorxiv.org/content/10.1...
We discovered that sperm hyperactivation drives stochastic switching between circling and wandering behaviors in complex fluids, and promotes an adaptive chemotactic strategy with both local exploitation and broad exploration!
