"We are living with the legacy of the McCarthy era, and what Donald Trump is doing is really resurrecting the worst."⁠ ⁠ After a performance of "Are You Now Or Have You Ever Been," @dlnyclu.bsky.social spoke at a talkback on the attacks we're enduring on free speech and the fight for our democracy.⁠

Very excited about our recent preprint- @lindashuyingxu.bsky.social and collabs discover that neutrophils repurpose their nucleolus for storage of pre-made IFN-I to be rapidly released via a nucleolar stress response that results in nucleolar extrusion and secretion. www.biorxiv.org/content/10.6...

Absolutely beautiful paper by a core team at the RIKEN in which the telomerase RNA component has (finally) been identified, in the nematode *C. elegans*. Surprisingly, it does not have its own promoter, but is located inside the intron of a germline-expressed gene (nmy-2)! 🤩 doi.org/10.1126/scie...

Nematode telomerase RNA hitchhikes on introns of germline–up-regulated genes
Telomerase is a ribonucleoprotein complex that elongates telomeric DNA, ensuring germline immortality. In this study, we identified the Caenorhabditis elegans telomerase RNA component 1 (terc-1), as t...

#DBfeature VEGF signalling promotes blastema growth and proliferation of both vascular and non-vascular cells during axolotl limb regeneration By Aaron Savage et al. tinyurl.com/3xs4nffs
VEGF signaling is required for blastema growth and the effect of VEGF inhibition is reversible. (A) schematic of experimental design; (B) representative DMSO-treated limb at 11 dpa (scale bar 100 μm; arrowhead indicates blastema; dashed line indicates amputation plane); (C) representative AV951-treated limb at 11 dpa (scale bar 100 μm; arrowhead indicates blastema; dashed line indicates amputation plane); (D) AV951-treated blastemas are significantly smaller at 11dpa; (E) representative DMSO-treated limb at 22 dpa (scale bar 100 μm); (F) representative AV951-treated limb at 22 dpa (scale bar 100 μm; arrowhead indicates blastema); (G) AV951-treated limbs show no regeneration at 22 dpa; (H) skeletal prep of representative DMSO-treated limb at 22 dpa (scale bar 250 μm); (I) skeletal prep of representative AV95-treated limb at 22 dpa (scale bar 250 μm); (J) AV951-treated blastemas display blocked regeneration compared to controls; (K) AV951-treated blastemas can develop to palette stage upon treatment removal

The epigenome is sensitive to metabolic inputs and is crucial for aging. Lysosomes act as a signaling hub to sense metabolic cues and regulate longevity. We found that lysosomal metabolic pathways sig...

A federal judge in Boston said she found it "difficult to conclude anything other than that [the Trump administration] used antisemitism as a smokescreen for a targeted, ideologically-motivated assault on this country's premier universities, and did so in a way that runs afoul of [federal law]."

I was born in the McCarthy era, but this is McCarthyism on steroids. Our democracy is under dire threat. But we have a government of laws, not men. And NO ONE is above the law.

Last week, House Democrats opposed giving Elon Musk and Trump a blank check funding bill that would allow them to gut programs and services families rely on. The Senate must pass a short-term spending bill so we can pass bipartisan bills that protect programs for our communities.

KEEP CALLING. PEEL OFF ALL DEM SENATORS YOU CAN. ☎️: (202) 224-3121 Tell them to vote NO on Cloture and NO on CR. Vote is pushed to after 1:15ish for now. Situation is fluid. The only public YES votes are Schumer and Fetterman. They need 7-8 total. KEEP CALLING. Call retiring Senators too!

CALLS ARE WORKING - it has bought us precious time, but we NEED to keep the pressure up. Tomorrow is the cloture vote. KEEP CALLING: (202) 224-3121 ☎️☎️☎️ Tell your Dem Senator to vote NO on Cloture and NO on the Republican spending bill. Do NOT assume your Senator will be good on this. Trust me.
