The savings we're getting here by annihilating decades of American science will pay for whole minutes of the operation to create decades of death, immiseration, and chaos in Iran.

A new context that show the importance of Neutrophils and LTB4!!

these are amazing! it’s so scary to be in the situation with a loved one and not have a clear idea of whether it’s worth it to epi-pen since my understanding before this was that always meant 6 hours in the ER.
Clear guidance is a god send here and will have me pushing for epi administration more.

So happy to be making my return to @ascbiology.bsky.social CellBio after attending as an undergrad in 2019. It’s been an amazing conference and I’ve loved learning about all the different nuclear biology research being done!

that being said i think it’s very rarely necessary.

caveat that all my experience is with magnetic dynabeads not sepharose.

pre-clearing lysates help a lot when your lysates are particularly sticky (if your medium is dense or there or in nuclear fractions with chromatin present). tradeoff is that your are depleting your sample but hopefully mostly of non-specific interactions.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

It’s fortunate that preprint servers are already well-established and robust. As an early career researcher, I still find the pull to publish as prestigiously as possible for my first paper. Recently I’ve started the painful process of disabusing myself of this notion.

With recent NIH news it seems much more plausible that the demise of Journals as the de facto method of sharing science is eminent.

How to be a scientist in a post-journal world When we created this site to write about things in science that need to be fixed, we chose not to start with publishing, even though it has been our preoccupation for decades.

This article by @pracheeac.bsky.social and @mbeisen.bsky.social sums up (in much stronger language) a lot of what I heard in a recent talk by Gary Ward (U of Vmt).

Really compelling argument to get rid of p-values in cell biology in favor of confidence intervals. Everytime I think about the state of statistics in biological research it makes me want to run, hide and become a statistician. rupress.org/jcb/article/...

Fascinating study with absolutely mind-blowing good EM images. I’m curious about these trimmer and junction points that form in the HFs. How stable are these structures? Is there a unique lipid composition required for this?

Also, is the idea that this is limited to HF structures or canon MVBs too?

Many brilliant scientists are now being punished by having our funding terminated because we are from underrepresented groups. We did everything right and we EARNED these awards.

Nucleoplasmic signals promote directed transmembrane protein import simultaneously via multiple channels of nuclear pores - Nature Communications The contribution of central and peripheral channels of nuclear pores to transport of transmembrane proteins is unclear. Here the authors show that most inner nuclear membrane proteins use only periphe...

This adds to another fascinating paper showing that membrane proteins like lamin B receptor travel not through the central channel at all, but around the side of the nuclear pore complex through a peripheral channel.

Incredible findings regarding the mechanism of active transport through Nuclear Pore Complexes. Seems importin travels only through the periphery of the central channel leaving a large dead zone in the center.
