Did Thoreau encounter contagious cancer? A new study finds transmissible tumors in catfish--and raises questions about whether they could arise in humans someday. Gift link: nyti.ms/4whfi6v

Deep in This Lake, a Contagious Cancer Is Spreading (Gift Article)

Transmissible tumors have been reported in a handful of animal species, but never before among fish. Is it possible in humans?

You might call them fire flies, but I call them lightning bugs, either way there's a whole lot of them!

Has anyone observed mNeonGreen getting brighter after photobleaching?

🚨Preprint alert! If you you’ve been following the centromere field recently, you’ve seen some (excellent) work showing that repeat copy number is highly variable in centromere region leading to massive variation in size. Here we try to understand how that variation impacts centromere functionality:

Several years ago I switched to drinking mostly decaf coffee. I still have a single cup of regular per day, but decaf is part of life now. I went to a coffee shop to do some work and I ordered a decaf carmel latte. This did not go according to plan...

My quote of the day You build on failure. You use it as a stepping stone. Close the door on the past. You don't try to forget the mistakes, but you don't dwell on it. You don't let it have any of your energy, or any of your time, or any of your space. Johnny Cash

I don't use AI on an everyday basis or nearly at all. I have been looking for a paper which I remember that showed expansion of bio samples so large that they are visible to the naked eye. I asked copilot and it found it immediately. It even gave me a real link that worked. I am devastated.

It's always funny to see these. The bar for effort on these type emails is so low. I believe in you, you can do it.

Has anyone tried using mesoscope.scripps.edu/beta/index.h... and CellPAINT2D to try to illustrate/simulate phase separation? You can make multivalent interactions, but they don't unbind, at least that I can figure out.

This week is #CRC25 — our annual Crossroads Research Conference! A time for our community to connect, share discoveries, and spark new collaborations. Hear from attendees including @jeffjlange.bsky.social & @juliannahaug.bsky.social ⬇️

Sweet! Very excited to read this paper on the transcriptome AND proteome of stress granules both from yeast and mammalian after treatment with azide/arsenite. www.cell.com/cell-reports... I've always wondered if the contents are there by accident, or on purpose to maintain the phase/granule.

I'm looking to database organelle dyes which work in fungi. Please comment if you can contribute w/ details. We regularly see @mrccmm.bsky.social that some don't work in some fungi, but I just don't think it's been tested properly #Mycoscopy I started this w/ Alex Lichius years ago, tip of the 🧊!
