What is a viral mimicry transcript?

My take for extinction drive is that they should first be carried out against invasive mosquitoes species in Europe or the US, which mitigates both ecological and ethical risks

Shouldn’t it be called a reverse translatase tho?

The @jimboonya.bsky.social lab at Fred Hutch found the use of sirolimus #GVHD prophylaxis in allo HCT recipients was linked to a higher risk for RSV infection, whereas higher serum neutralizing antibody levels were linked to a lower risk in the first 100 days post-transplant. wb.md/3Zokzua

RSV Antibody Levels Tied to Posttransplant Infection Risk
After hematopoietic cell transplant, sirolimus use for GVHD prophylaxis is linked to a higher RSV risk, whereas higher serum neutralizing antibody levels are tied to a lower risk within 100 days.

Getting asked about how academics can continue to do science & inspire trainees even in the midst of a continued (escalated) assault on science, reason, truth, & human rights. I don’t have great answers. I would love to hear from mentors about advice they’re giving to trainees/ colleagues.

A cGAS-mediated mechanism in naked mole-rats potentiates DNA repair and delays aging Naked mole rats get much older than closely related mamals of a similar size. cGAS mutations may have an important role in this. www.science.org/doi/... 1/9

A cGAS-mediated mechanism in naked mole-rats potentiates DNA repair and delays aging
Efficient DNA repair might make possible the longevity of naked mole-rats. However, whether they have distinctive mechanisms to optimize functions of DNA repair suppressors is unclear. We find that naked mole-rat cyclic guanosine monophosphate–adenosine ...

hey bluesky 👋 visa hurdles mean I’m looking for opportunities outside the US. I’m a computational biologist (bacterial + phage genomics, postdoc in Koonin’s group @ NIH). I am interested in teaming up on funding apps. reach out if this resonates!

This is the norm in many countries, but I think it’s a shame to lose it. I always thought it was one of the great feature of US PhD programs

🥳 Very grateful for the support of the ERC Starting Grant for my newly established lab! We will study how transposable elements contribute to mammalian embryonic development. We will have positions available next year. Stay tuned!

Pretty surreal to see my artwork on the cover of Nature Genetics! Big congrats to @julianeg.bsky.social, @stemundi.bsky.social and the others, and thank you Juliane for letting me help bring your research to life visually. www.nature.com/ng/volumes/5...

The payline in this context is the proportion of grant proposals that are funded by NCI. So we’re going from 10% to 4% of proposals receiving money

I don’t think this is Bluesky’s fault or that anything changed tho. It’s just that American users are in deep trauma and that sets the tone

There will be, maybe, for the lucky few, but the math do not work at scale. And wait until you find out how much you would get paid in a lot of other countries…

The one question I always have with this (very cool) experiment is why you decided to start from both side with the high concentration in the middle, and not have just a gradient of antibiotics from one side to the other?

“One young man sobbed when a guard pushed him to the floor. He said, ‘I’m not a gang member. I’m gay. I’m a barber.’ I believed him. *** He “began to whimper,” as his head was roughly shaved, “folding his hands in prayer as his hair fell.” He “asked for his mother & cried as he was slapped again.”
