Congratulations to Biology Ph.D. student Taylor Rubin, who won a 2026 Katherine S. McCarter Graduate Student Policy Award from the Ecological Society of America!

"The acting director of the Centers for Disease Control and Prevention (Jay Bhattacharya) has delayed publication of a CDC report showing the covid-19 vaccine cut the likelihood of emergency department visits and hospitalizations for healthy adults last winter by about half."

"Rip1 uses these phage protein ring complexes as a template to assemble into membrane-disrupting pores that inhibit phage virion assembly and cause premature death of the host cell."

Which type of Scientist are you?
I don't remember where I got this but found it going through some very old files. NB: I am a Geek.
Bacteriophage data on capsular Klebsiella bacteria barcoded library
New paper 🔔
Collaboration
@sullivan-lab.bsky.social
Marissa Gittrich led the work
Klebsiella phage biology has focused almost entirely on capsulated strains, but capsule loss is the #1 resistance mechanism under phage predation. We used a naturally acapsular host to reveal the receptor landscape
I'm a big fan of bioRxiv, so it was fascinating to dig into the stats behind the rise of this preprint server from its first 13 or so years for Nature News @nature.com 🧪 @biorxivpreprint.bsky.social #preprints

Capturing dynamic phage–pathogen coevolution by clinical surveillance
"we capture the acquisition of a parasitic anti-phage mobile genetic element, PLE11, that initiated a selective sweep coinciding with the largest cholera outbreak in recent records. "

The're also doing untargeted deep sequencing of wastewater RNA. Cool project! naobservatory.org/casper/

Four scientists pose outside of City Hall park at the Stand Up for Science rally. One holds a poster saying “An attack on scientists is an attack on everyone”
@queenscollegecuny.bsky.social scientists at the @standupforscience.bsky.social rally today!
If you block junior scientists from ensuring that they can afford to live (or start families!) in the exorbitantly expensive areas around their workplaces, only family-subsidized solitary rich kids will be able to pursue careers in research - amidst exponential inflation, increasingly few people.
Current NIH leadership want you to think they are using rigorous, consistent & scientific processes to screen studies to align them with agency priorities.
But the process that they have put down on paper is a sham.
It’s important to know NIH is not following its own guidance. Here’s why:

Stand Up for Science
New York City National Day of Action Rally!
Saturday, March 7, 12pm - 2pm
City Hall Park
Rally to defend scientific integrity, protect public health, and protest political interference in the scientific enterprise.
Meet PSC members at the Broadway and Park Place entrance.
Hoping for a big turnout tomorrow!
Sabotaging the NSF fellowship is a blunder
"After making a massive mistake of curtailing the entry of excellent foreign-born scientists, the administration is compounding the error by further restricting the development and availability of domestic scientists."

Thank you for your service @nmrkaygee.bsky.social !
New paper showing that bacteria with more genes for cooperation can live in a broader range of habitats and that genes for cooperation are more more likely to be in the accessory genome www.pnas.org/doi/10.1073/... @lauriebelch.bsky.social
In our latest work, we characterise the Tmn defence system. We reveal plasmolysis as a new way to block phage infection, dramatically reducing secondary infections.
Great profile of @ntidpres.bsky.social in the @themindhears.bsky.social

I’ve spent a lot of time over the past two years thinking about genome evolution and how recent research revealing complex gene-gene interactions has complicated traditional ‘gene-centric’ genomic approaches to evolution. So here is a review that consolidates these thoughts!

With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268
The number of researchers who*don't even respond* to review requests is appalling. If you can't or don't want to review, fine. But don't waste everyone's time by ignoring three or four emails that can be dealt with one click.
Claire Shipman is a former television journalist, and it shows.
Going live to tape and telling the world how your university was invaded and your student abducted on the same day is exactly how you fight authoritarianism.

I'll translate it for you Dave. There's going to be a small club getting funded and you're not in it.
Grantmaking will become industrial policy executed through academia.
