Last year’s air pollution conference at the RSC was a sell-out, so we are running it again in collaboration with DEFRA’s Air Quality Expert Group, with presentations and discussion focused on the group’s work on airports, amines and carbon capture and wildfires. www.rsc.org/events/find-...

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

Very sad to hear this news. I knew Peter for many years and could always count on him for a robust yet completely respectful debate. I still credit him with enabling the success of one of my grants after he really made me think about what we we doing and why. One of the good guys. RIP.

Closest is vaping for the spatial distribution but showing risks for different viruses is very challenging as it depends on infector emissions and host susceptibility as well as the physics of flow. We know that some people emit far more than others for all respiratory pathogens

Prof Cath Noakes @cathnoakes.bsky.social · 14/05/2026
Agree. I wonder if it’s because people can’t picture spatial variation in exposure risk and so associate inhalation to mean all of the air is equal risk rather than highest risk close to source.
