Hi to my new followers!
I am a virologist at @fredhutch.bsky.social in the team of Keith Jerome.
If you are curious about what I do here are 3 options for you:

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.

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!

🥳 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!
📣 The ERC Starting Grant call results are out!

Find out which early-career researchers will receive funding this year, what they will be investigating, where they will be based... plus lots of other #ERCStG facts & figures for 2025!

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.

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.

⚠️ 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 got hit by some rather sudden and extreme financial hardship so if anyone is in need of remote wetlab contract research, strictly BSL1, do let me know. Currently scrambling for gigs.

“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.”

Pet peeve: I hate how often ppl claim “all the researchers will just move to Europe/Canada!” You vastly under-estimate how little money there is there vs the USA- and unless that changes ASAP this loss is just going to decimate global science, full stop. 🧪🔭

I have been doing entirely too much earnest posting about deep things recently, I need to do a proper thread about hippo testicles or something just to keep myself sane.

Oh by the way hippos have migratory testicles.

I maxed out my credit card, emptied my savings account, and took out a loan to move from Alabama to Bethesda, MD. I don’t even qualify for unemployment since I’ve only worked at NIH for a month. I will be financially and medically devastated.

Seeking suggestions for anywhere that’s hiring!!
Today, along with 2,000 other NIH employees, I had to clear out my office 😭

It was truly the honor of my life to work with such incredibly passionate people focused on improving human health. I’ve never experienced a more positive culture where *everyone* cared about their job and serving others.

I’ve unfortunately needed to add more material to my post from yesterday. The re-election of Donald Trump is looking like the biggest act of American self-destruction since the Civil War.

I love to see our work pops up in my feed!
Glad you liked our paper and thank you for sharing it
New hope for viral coinfection-based therapeutic approach against Herpesviruses!
Gene Drive(GD), a self propagating gene-editing technique via Cas9 mediated homologous recombination inserts the GD with red fluorescent (mCherry) into HSV-1 genome. Specific and non-specific (GD-ns) gRNA were tested.

Do you know who Douglas Prasher is? Many don't, even though he is the person who cloned the original #GFP gene in the late 1980s. In my short history of plant light #microscopy I also cover a bit of his story - & why he is relatively unknown today, despite the importance of his work. See this 🧵👇
