Bad hearing, bad sight, scattered brain.
Full of PFAS, but a true believer in radiation hormesis.
Why isn't rutile rutilant?
I like valence electrons (but K shell too) & deep time.

Another cool result shared at #RockyWorlds4: Nearly all sub-Neptunes, if they are gas dwarfs (as opposed to water worlds), should have magma oceans beneath their hydrogen atmospheres.
That includes the notorious K2-18b — if it is indeed a gas dwarf and not an ocean planet.

Why on earth don't all state schools have access to high-quality resources they can distribute for free? Online or paper. Huge inequality being perpetuated here.

Teen asked me to get another textbook because the school can't afford enough for a copy each and some of the resources are crappy GenAI. So far I've spent about £200 on school books this year and wtf are we doing?

4yo asked what happens to our "old paper" (recyclables).
We watched some films on carton recycling and paper mills. None of those films conveyed the stench of actial paper mills, but anyway.
Now the kid is snippering paper and mixing with water. "Look, pulp!"

Too sick to entertain him, I'm letting the oldest watch Planes 2 again. The two characters sheltering from the wildfire in the mine just seemed so familiar but I couldn't remember the details.

Very cool animal study, and even better, could lead to a new technique for a host of airborne pathogens.
Looking forward to clinicals!

GOOD NEWS! Researchers have developed a nasally delivered, antibiotic-inactivated Bordetella pertussis (AIBP) vaccine that NOT ONLY prevents SEVERE disease BUT also CURBS bacterial TRANSMISSION. This NEEDLE-FREE AIBP platform could open the door to new vaccines against other respiratory bacteria.

Vaccinations for pertussis lasts a few years at most.
A mother can get a booster and small children have it in their vax schedules, but every adult happily visiting a newborn is *not* immune, bc adults don't (normally) get boosters.

many infants from severe disease. Yet outbreaks still occur in countries with high vaccine coverage, and the illness continues to circle back every few years. The problem lies in where protection starts and ends. Current acellular pertussis shots, the ones many children receive, work well at

So you end up with a situation where you can ostensibly find evidence for all sorts of mechanisms that's actually just confounding. I think it's bad that this type of analysis has become such a major tool driving theorizing, given how easily it can fail.

Reviewer notes: That’s a very nice mediation analysis you have there. It would be a shame if something happened to it.
Mediation analysis has gotten a lot of flak, including classic titles such as “Yes, but what’s the mechanism? (Don’t expect an easy answer)” (Bullock et al., 2010), “What mediation analysis can (not) ...

The Tasselled Wobbegong is a master of disguise that can eat a fish almost as big as itself in one gulp. It's classified as a shark, but when it lays on the sea floor it looks like a harmless rug if you manage to see it. But with powerful jaws and sharp teeth they are no fish to mess with.

the solution to pollution is munition
This was the disposal procedure for unwanted reactive chemicals waayyy back 😱
You gave them to the army bomb guys for blow up practice.
1. Cover cylinder with charges
2. Bury in a hole
3. Retreat a safe distance, not downwind
4. Blow it up

Store wouldn't do it - their system threw a "chemicals" restriction on shipping to NY.
Sales guy said this has happened before & reason is "the shoes have nitrogen."
He didn't care when I told him he's breathing ~80% nitrogen.
