Delighted to share our discoveries about one of the brain's neurotransmitter systems:

Together with colleagues at the @alleninstitute.org, we have learned a lot about a tiny cluster of neurons in the brainstem locus coeruleus (LC) that releases norepinephrine (NE). 1

Last year, Republicans gave ICE $75 BILLION – more than most militaries across the globe – while refusing to fund your health care.

I fought it then and I’m fighting it now. I’m voting NO on DHS funding.

Boxing up the NSF at Eisenhower Av for the forced relocation. Boxes have “Details Matter” signage.

Boxing up the NSF at Eisenhower Av for the forced relocation. Boxes have “Details Matter” signage.

NSF

- Forced reorg

- POs down ~ 40% (DRP, most rotators not renewed, retirements)

- Forced move (and we have to pack and clean) to a building with no furniture, little to no conference space for panels, inadequate 🛜, …)

I personally love the boxes they gave us for packing.
“Details matter” 🙃

Anybody else worried that because of the long standing Republican war on SNAP people are going to experience painful hunger. Lets do something. @nanopharmnc.bsky.social and i are going to donate to some local nc food banks. Join us! Gonna match up to $500.

After 13 years in the US, I’ve made the difficult decision to leave. Having packed up everything and rethought about priorities, rather painstakingly, while I’m sad to leave the life I’ve made here, I’m also relieved that I won’t have to plan my life around immigration policies anymore.

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!

We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

The NIH institute director firing last Friday is very bad.

I made a video explainer about why.

I made a video about the shutdown, and why this government worker won’t be a pawn.

When the president and Supreme Court are both acting lawlessly, Congress must stand up and stop it.

US science is collapsing and Congress needs to act.

basic research on wacky things like Gila monster venom are what gave us GLP-1 drugs that are treating diabetes, obesity, & addiction in new ways

this piece from @whyy.org is great

an analogy: navigation apps are great but don't tell you how to climb Mt. Everest & survive

The Nobel Prizes, 5 of 6 having so far gone to US based scientists, are a reminder of why we must stand up for science against this horrid administration. Here are some great Scientist Activists to follow.

So many academics are on HB-1 visas. This is another attack by #RussellVought on universities and scientific research. Stop telling me anything this administration does is in good faith or with any sort of policy goal except destruction.

Whether or not you are a US scientist, you’ll know that this US administration’s reckless ideology endangers the entire globe - the trajectory of human civilization and all life on Earth. Scientists please sign.

Adaptive learning is coordinated across behaviour, time and neurobiology (from synapses and dendrites, to astrocytes and the systems level).

The biggest violent crime spree in Washington, DC, happened on January 6, 2021, and Trump pardoned hundreds of violent felons who were part of that.

New executive order puts all grants under political control All new funding on hold until Trump administration can cancel any previously funded grants.

All scientific grant funding must now be approved by a political appointee and "demonstrably advance the President's policy priorities."

I wonder where innovation will happen in the future? It won't be in the US
