Meet some of the team, get a little pep-talk from Nobel Laureate Dr. Victor Ambros, take action in community, AND get an infusion of hope.

Sounds like the perfect evening activity to me! See you there.

Top: CD133 showed specific enrichment on the apical surface of radial glial cells (RGCs) in the developing ventricular zone (VZ) from postnatal day 0 (P0) to P15. Ciliary membrane marker (ARL13B) and the ciliary microtubule marker acetylated-tubulin (ac-TUB) indicated ependymal cell (EPC)-lineage differentiation. Cell proliferating marker (Ki67) and neural stem cell (NSC)-lineage marker (ASCL1) indicated NSC-lineage transition. The framed region was further magnified to show details. The boundary between lateral ventricle (LV) and VZ was denoted by the yellow dotted line for better distinguishing ciliary ac-TUB and cytoplasmic ac-TUB in (B). The scale bars are 20 ΞΌm. Bottom: A model illustrating how TFEB functions in the process of bGPC specification during VZ development.

From Senator @murray.senate.gov: the Senate's proposed NIH budget would reject 40% cuts, increase funding by $400M.

"We're not going to give up the fight against cancer, Alzheimer's or rare diseases."

Message to scientists: "we support you. We need you to stay here & keep this research going."

The NIH budget will INCREASE by $400 million β€” not slashed by 40%, as Trump proposed β€” according to a proposal by Senate appropriators, says Sen Murray.

"Some have asked if there will even be an NIH by [2029]. The commmittee's resounding message is yesβ€”Congress has your back", she says.

Alert: The Trump administration is quietly slashing new NIH grant awards, and it's not via the budget NIH’s sudden move to multiyear grant funding is forcing shocking cuts in the number of grants funded. This is an effective budget cut. It's bad, folks.

New, from an anonymous NIH insider: Trump is being pushed to spend more NIH money. The White House is ordering NIH to do multi-year budgets for awards. This budget trick means fewer awards, fewer labs funded, and lower paylines for researchers. 🧡
