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

The International AI Safety Report is clear-eyed: threats from AI are growing--to rights, autonomy, health, cybersecurity, and planetary well-being. The evidence is stronger than ever. Commitments from industry and government to the safe, trustworthy, and responsible use of AI are urgently needed.
Today we’re releasing the International AI Safety Report 2026: the most comprehensive evidence-based assessment of AI capabilities, emerging risks, and safety measures to date. 🧵

We are deeply saddened by the passing of Councillor Waseem Zaffar. A stalwart advocate for clean air, social justice and children’s health, Waseem was a true supporter of us and our Birmingham work with Kirsten and Maya. Our thoughts are with his wife, children and family.

In 1988, the BBC paid tribute to the heroic work of the humanist Nicholas Winton, an English stockbroker who saved more than 650 Jewish children ahead of WWII on the Kindertransport. Winton, sitting in the audience, was not aware he was sitting among the very same people he saved. Beautiful.

The world should not come here. There should not be a World Cup here.
I spoke out against the last World Cup because of concerns I had about human rights violations and it’s only right that I express the same concerns and condemnations now.

Had a wonderful day last week at the launch of the HESTIA Network (hestia-network.org).
It was really great to talk with such a varied group about how we can make homes that are good for people, the planet, and justice (however we might define it!).

“I don’t care that you didn’t give me the Nobel Peace Prize. I don’t care about peace anyway…”
Not the sort of letter committed to paper by a well man. "Considering your Country decided not to give me the Nobel Peace Prize for having stopped 8 Wars PLUS, I no longer feel an obligation to think purely of Peace"
