hard to think of a better example of "you may not believe in class war, but billionaires know they're in one" than this

GOOD NEWS! A UNIVERSAL sarbecovirus vaccine candidate has officially started clinical trials! GBP511 is the FIRST vaccine to reach human testing that is intended to protect against MULTIPLE strains of SARS-CoV-2 as well as other related coronaviruses with the potential to spark dangerous outbreaks.

This is an amazing post to pick out all the Russian sockpuppet accounts. If it starts with a "I am member of LGBTQQQ+ leftist atheist autist and <what about ...>", there's your cue.

Carrot incentives only work for the keeners. Stick is needed for the rest.

The risk of the airborne transmission of disease correlates with the amount of infectious exhaled aerosol. Since people exhale CO2 with aerosol, its conc has been used as proxy for exhaled aerosol

In this article, researchers propose a new way to estimate risk of transmission

You can very much use this as a "gotcha" take, but Gregor Robertson would feel very inadequate.

Important paper. Schools are high-risk environments for respiratory disease transmission MAINLY because classrooms are underventilated. This problem has a workable solution - it just needs political will. Air quality is as important as water quality for public health. MT @martinmckee.bsky.social

Canada set to scrap EV mandates in new national auto strategy, sources say | CBC

Some more 4D chess to dupe the industry into meeting climate change target?

Am I just dense and missed the sarcasm?

These folks are being... serious?

Active investors say only active investors can "efficiently" allocate capital?

Did... I miss something?

If passive investing is inefficient, that should create huge opportunities for active investors to make mint. Should they not welcome it?

This is new to me. Google brought this up: fortune.com/2025/12/06/i...

Is that the "scare"?

Oh man, I wonder when they'll have a fake AI HR avatar fire people over Teams... and then immediately brick their computer.

France dumps Zoom and Teams as Europe seeks digital autonomy from the US European governments are moving away from U.S. tech giants, opting for domestic or open-source alternatives.

You've probably heard by now that the Conservative Party convention voted to keep Pierre Poilievre on as their leader.

What you may not have heard about, however, is the *other* stuff the delegated voted on over the weekend.

Some of it is...predictable. But some of it is downright concerning:

Jeffrey Epstein emailing Peter Thiel: Finding things on their way to collapse was much easier than finding the next bargain. ... Return to tribalism. Counter to globalization. Amazing new alliances.

Definitely seems like they destroyed the country on purpose.

Feasibility and Safety of Aerosolized Influenza Virus Challenge in Humans Using Two Modern Delivery Systems This study demonstrates that aerosolized influenza virus can be safely administered to healthy adults using two modern delivery systems. Controlled aerosol

To study influenza infections, we inoculated human participants with aerosolized virus: coarse particles generated by a flow-focusing monodisperse aerosol generator and fine particles generated by a medical nebulizer. academic.oup.com/jid/article-...

Europe just started building a ‘kill switch’ for U.S. tech — and the market isn’t priced for it, says this strategist — MarketWatch Zoom and Microsoft are among those companies that could lose business, says Matthew Tuttle

“The main event is this: the world is building optionality away from U.S. policy and platform dependence. And once you see it, you can’t unsee it — because it’s showing up in procurement decisions, supply chains, defense budgets, and capital flows”

"We don't see a lot of airborne transmission in [some] hospitals!"

Well, yes, that's because it's being taken care of with airborne protection measures...

caveat: different hospital standards, vintages, maintenance, etc.

One reason why nosocomial or HAI infections are sometimes hard to detect or trace in healthcare settings is because mechanical engineers try to manage airborne infections.

Europe wants to end its dangerous reliance on US internet technology As the US increases political pressure on Europe, it’s possible to imagine the continent losing access to key computing services.

“Technical failures, cyber-attacks and natural disasters can all bring down key parts of the internet. And as the US government makes increasing demands of European leaders, it is possible to imagine Europe losing access to the digital infrastructure provided by US firms.”
