How fast does a protein fold? Real-time technique captures the moment Proteins assume complex 3D shapes even faster than does DNA, which is a simpler molecule.

Scientists say they have made some of the first direct measurements of how long it takes an individual, ordinary protein to fold – and the results were surprising.

My colleague @alexwitze.bsky.social joined @scifri.bsky.social today to break down our reporting on how the White House is withholding funds from science agencies.

One researcher dials in to say her institution is waiting on $20 million in research funding.

New version of our preprint on bioRxiv about bioRxiv up. Now that’s what I call a revision – 6 years after the first version!
It has new data about our progress and highlights from a massive user survey. 1/n

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. 🧵👇

This is correct ✅ 🍊

As of tonight, licenses of trans people across Kansas are being invalidated en masse, enabling the overnight criminalization of an entire group of people for going about our lives. It’s often said you never know when you’re living through history, so let me assure you: that’s what’s happening now.

Ugh.
