It'll be pretty embarrassing if the dinosaurs went out with more dignity than us.

They can't say they knew about the meteor for decades, knew exactly what to do about it, had all the technology and resources to stop it but didn't so five of them could own everything

Hiding in plain sight: Animals eat the natural bioplastic PHA

We discovered that many animals can break down PHA. And many of these enzymes had been sitting unnoticed in genome databases.

The origin of turtles has always been a bit of a puzzle for scientists who study the evolution of animals.

Turtles finally have a place in the tree of life:

New preprint from @pawley.bsky.social @scottnichols.bsky.social is a great testament to how intentional imaging helps untangle potential functions and mechanisms of host-microbe interactions

I find it *extremely* disturbing that Jay Bhattacharya—who campaigned for RFK Jr during RFK’s Presidential run—is repositioning the NIH to be the research arm of RFK Jr’s anti-vaccine, anti-science MAHA movement😨
“I want the NIH to be a central driver of the MAHA agenda,” Bhattacharya said. “Essentially, it's kind of the research arm of MAHA.”

NIH is not an ideological toy or 'arm'. We must insist on its scientific independence, especially if its Director will not.

This is one my favorite images I’ve ever taken of a freshwater sponge

The depth-coded image (stained for F-actin) beautifully shows the static nature of the choanoderm and the extremely dynamic nature of migratory cells along and around the outer epithelia :)

There’s a nonzero chance you will die from a cancer that could have been curable because people who couldn’t pass 7th grade biology and are scared of things like “mRNA” and “riboflavin” and “walkable cities” decided to make their ignorance everybody else’s problem
Over 120 mRNA cancer trials are now at risk as the Trump admin cuts funding & tells researchers to scrub “mRNA” from grant proposals.

What started as COVID fearmongering is now derailing life-saving cancer research.

Hope remains - but scientists say time is running out.

If we all somehow agreed to follow some unwritten rule that nobody can publish more than four or five papers per year, I think that would make our culture healthier for everybody.
