I’m excited to share my recent postdoc work. Here, we interrogate how different phage infection outcomes (productive vs. restrictive) affect the expression of phage defense systems. We find that a restricted infection not only inhibits the phage but also induces increased immune protein abundance.

Complete nonsense.
My advice to post-graduate researchers is to always preprint their work, as it will improve their visibility while the manuscript is going through a (frequently very long) peer review process.

We have senior people in our department telling PhD students not to post preprints as journals will refuse to publish due to prior publication. Is there anywhere in health this is actually true? Genuine question, but I doubt it?

R&D on CO₂ removal (CDR) should be funded and led by governments, like the Manhattan Project minus the nuclear bomb. That way we can figure out what works and what doesn't technologically, environmentally, socially, etc.
R&D on CO₂ removal (CDR) should be funded and led by governments, like the Manhattan Project minus the nuclear bomb. That way we can figure out what works and what doesn't technologically, environmentally, socially, etc.
![Getting it right will require governments to take a larger role in the sector than just subsidizing it, argues David Ho, a professor at the University of Hawaiʻi at Mānoa who focuses on ocean-based carbon removal.
He says there should be a massive, multinational research drive to determine the most effective ways of mopping up the atmosphere with minimal environmental or social harm, likening it to a Manhattan Project (minus the whole nuclear bomb bit).
“If we’re serious about doing this, then let’s make it a government effort,” he says, “so that you can try out all the things, determine what works and what doesn’t, and you don’t have to please your VCs or concentrate on developing [intellectual property] so you can sell yourself to a fossil-fuel company.”
Ho adds that there’s a moral imperative for the world’s historically biggest climate polluters to build and pay for the carbon-sucking and storage infrastructure required to draw down billions of tons of greenhouse gas. That’s because the world’s poorest, hottest nations, which have contributed the least to climate change, will nevertheless face the greatest dangers from intensifying heat waves, droughts, famines, and sea-level rise.
“It should be seen as waste management for the waste we’re going to dump on the Global South,” he says, “because they’re the people who will suffer the most from climate change.”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:77lswp42lgjyw36ozuo7kt7e/bafkreifm6z2ot7oa4aovmkiahghmff3gpq34dsxp2sxjf2s7uq45weo35a@jpeg)

Bacteria use paralog teamwork to survive stress.
H-NS forms fluid condensates; its partner StpA forms rigid fibrils. Together, they balance flexibility & stability to keep genes properly regulated under pressure.
