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.

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. https://wb.md/3Zokzua

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 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 ...

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.

hey bluesky πŸ‘‹ 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

πŸ₯³ 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!

In France 90% of the milk is UHT for some reason, and I think it’s pretty high in other European countries too

Mortality Rates, Mortality Rate Ratios, and Excess US Deaths Attributable to the US Mortality Disadvantage Relative to Other High-Income Countries (HICs)

Mortality Rates, Mortality Rate Ratios, and Excess US Deaths Attributable to the US Mortality Disadvantage Relative to Other High-Income Countries (HICs)

Super interesting deep dive into US excess mortality. We're doing better than we were in 1980 but a *lot* worse than every other high-income country.

The cover of Nature Genetics July 2025 issue. Digital art of a mouse paw skeletal prep on dark background, digits I to IV disintegrating into viral particles. A caption says β€œAn endogenous retrovirus causes limb malformation”.

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.

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

⚠️ Discovery of a new mode of viral transmission:

Deltaviruses spread through a viral Trojan Horse !

These viral satellites that do not encode their own glycoproteins, are in fact physically encapsulated within their helper virus particles!

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…
