New preprint 🥳! We made photoclickable HaloTag ligands to precisely control protein labeling on living cells. With it, we can do some cool multicolor stuff. Huge congrats to Franzi and all co-authors! Check it out 👇

Many sea stars begin life as young fairy-like creature (called a brachiolaria) that float through the open ocean. Eventually, a small star forms within them (here in yellow). The fairy-like brachiolaria sinks under the star’s weight, and the star pops out!

It is out! 🦚 I recorded hundreds of #ExM 🔬images of cytokinetic bridges and averaged them into 6 stages. How? With help from our fantastic collaborators @zacsimile.bsky.social and @jonasries.bsky.social in Vienna 😇. Check out the full atlas here: doi.org/10.5281/zenodo.17232370

🧠 We discovered that neurons use endogenous fatty acids as an energy fuel, challenging long-standing models of sugars being the exclusive energy source for neurons. 1/3

Trump admin planning to change student visas from lasting for duration of academic program to fixed 4-yr term, and then much harder to renew
Could destroy US ability to attract global talent, particularly those seeking advanced degrees in STEM. The median time to complete a PhD is 5.7 yrs per NSF.

Trump Deals A New Immigration Blow To International Students
Trump officials have proposed a new rule limiting international students to fixed periods of entry, making a U.S. education more precarious.

It's #MicroscopyMonday, so let's take a look into the microscope! 🔬
This image shows muscle detail in the arms of the California two-spot octopus (Octopus bimaculoides), color-coded for depth. It was also the winner of the 2019 MBL Photo Contest!
