Expert reaction to unpublished paper modelling what percentage of the UK population may have been exposed to COVID-19 | Science Media Centre
It’s an interesting paper but consensus seems to be that it’s not a good reason to give up lockdown (it’s ancient history from back in March now, but some discussion going on on UnHerd after they interviewed one of the researchers).

Thin Pinstriped Line: The business of Remembering
Veteran and civil servant “Sir Humphrey” on poppies: “I have grown increasingly concerned at the manner in which manufactured outrage focuses on any organisation or individual that challenges the Poppy status quo, by not wearing one. If you are wearing one only because everyone else is wearing one, then perhaps it is time to ask whether the Poppy has become a victim of its own success.

As we move into the world where we are over a century on from the events of WW1, perhaps the time has come to ask if it is time to evolve the service of Remembrance, and perhaps do it differently. I do feel that the need to remember is always appropriate, but that the means by which a simple silence has become a business and outrage outlet to sell papers is increasingly distasteful. “

“Drs. Dorry Segev and Sommer Gentry are innovative researchers who connect the complexities of mathematics with the intricacies of organ transplantation.” They came up with using graph theory and integer programming to match up reciprocal kidney donors (that is, where someone wants to donate to their family member but they aren’t compatible, so they swap with another incompatible pair). These guys are also swing dancers, so this came via /r/SwingDancing.
