I wrote up my thoughts about the COVID origin. I don't plan to weigh in on the topic beyond this one post for the next five years or so. Looking into what the evidence says once or twice every decade feels like a good cadence. blog.genesmindsmachines.com/p/it-still-w...

If you want to worry about the dangers of AI, something like this is a much better place to start than an engineered bioweapon. t.me/MaxOsintInte...

I'm really frustrated by the constant fear-mongering about AI-designed superviruses. Can we focus on the things that should actually worry us, such as measles? blog.genesmindsmachines.com/p/im-sorry-y...

'There are deadly viruses all around us, and viruses routinely jump from animals to humans and cause severe outbreaks. This is a real, documented risk. This is the risk we should worry about. This is the risk we should prepare for. But instead, we worry about fictitious AI-designed viruses'

Learning from human and chemical languages to predict biological function Novel LLM AI approach trained on the literature Effective compounds in vivo for antimicrobial resistance Congrats UT Austin researchers Mavridou, Ellington, Wilke, Marcotte & colleagues www.biorxiv.org/content/10.6...
COVID awakens persistent viruses especially in the herpes and anello virus families. Cool example of RNA virus/DNA virus crosstalk. Maybe this adds to the inflammatory burden and misery. Congrats to UT Austin researcher Ester Melamed and co authors on this work. www.nature.com/articles/s41...
Timely podcast describing several stories of the real-world clinical impact derived from basic science starting with non-medical questions. Spot-on take from a wellness influencer who is not a practicing scientist. peterattiamd.com/medicalbreak...
Anik made a most excellent video explaining his work on viral persistence and reactivation…
Our recent work in the Sullivan Lab at UT, simplified in 90 seconds! I’ll be giving a talk on this work at ASV 2026 this July in Minneapolis. This video is for a general audience, and I’ll also submit it to a video abstract competition there. Happy watching!!! #ASV2026videoabstract

Yet another beautiful example of host-pathogen RNA communication. Fantastic work! Reminder to myself: READ MORE PLANT PAPERS! www.nature.com/articles/s41...

Chemotherapy that makes cancer cells look like they’re infected with a virus: ROS>ER stress>UPR>increased MAVS>Type I IFN/CXCL10
New research from UT Austin & MD Anderson Cancer Center reveals why some chemotherapy drugs not only eliminate cancer cells directly — but can also trigger the immune system to attack cancer cells as well. #CancerResearch #Chemotherapy @mdanderson.bsky.social cns.utexas.edu/news/researc...
Polyomaviruses are masters of persistence and dissemination: we show there are two forms of long-term persistent PyVs in the kidney: the majority being cryptic (non-shedding) and a minority that actively shed, and these fates are determined shortly after infection. www.biorxiv.org/content/10.6...

#WeekendRead #MysterySolved! MYC is one of the most famous #oncogenes & a potential therapeutic target but how does it work? Uhl, Eilers &co show @cp-cell.bsky.social that MYC binds introns during RNA stalling preventing export of dsRNA & DNA/RNA hybrids & anti-tumoral TLR3 activation!

I chatted with @philiprlang.bsky.social on his podcast about how a virus might be involved in bladder cancer. Since "Phil Lang is Not a Scientist", we made this really accessible. If you're interested in how small sneaky DNA viruses might contribute to the origins of cancers, give it a listen.

Although not covered in our review because of its more recent posting, there is a related important manuscript from Denise Galloway's lab: www.biorxiv.org/content/10.1...

🚨Preprint alert! Kind of a late notice, but here is our latest work on bat Dicer and viral infection. Work led by @leagaucherand.bsky.social and Hugo Marie in the lab. @cnrsbiologie.bsky.social @unistra.fr @frm-officiel.bsky.social www.biorxiv.org/content/10.1...
Small DNA viruses can concurrently shed via two different patterns: continuous low-level shedding of numerous reservoirs and punctuated rare high shedding from one or a few reservoirs. We hope tools presented here are useful to study other persistent pathogens. journals.plos.org/plospathogen...

Stop for a second and try to imagine this: a heat shock protein relocalizes to the cell surface and mediates dsRNA binding and internalization! Intrigued? Read our newly minted paper in Science Advances www.science.org/doi/10.1126/... Congrats to all the authors and thanks to reviewers and editor!

Another nice example of a host-acquired gene in poxviruses, which modulates the host immune response. dx.plos.org/10.1371/jour...
Previously, KO and overexpression showed host RNA 5’ triphosphatase DUSP11 can reduce RIG-I sensitivity. Here, we show poxviruses code for viral DUSP11 that can regulate host RNP III transcripts and RIG-I, providing evolutionary support DUSP11 can be pro-viral. journals.plos.org/plospathogen...
