An honour to be part of any Books of the Year list, but being chosen by a bookseller hits differently. Thank you to Nairn Bookshop for supporting 'Drystone' so generously.
They’ve also chosen 2 other excellent Scottish books, worth a look if you’re choosing gifts or planning your winter reading.

I solved my "I have too many books and not enough space" problem. Just gave six books away to the little free library near me! A win-win all around because hopefully more people will read about disability.

Bird flu viruses can replicate at fever-level temperatures, making them less susceptible to one of the body's key defenses and posing a significant risk for severe human infection.
Bird flu viruses are resistant to fever, making them a major threat to humans
Bird flu viruses are a particular threat to humans because they can replicate at temperatures higher than a typical fever, one of the body's ways of stopping viruses in their tracks, according to new research led by the universities of Cambridge and Glasgow.

Even if HPV only caused cancer in people with cervixes, it would be essential to vaccinate people without cervixes because they can carry and spread the virus. You don't control infectious diseases by only vaccinating the people who might die, you control them by vaccinating everyone.

I'll circle back shortly to share Gerard's results of this experiment (from Twitter)
@adamwong.bsky.social released AirFanta's wearable air purifier to market. It's meant to be used close to your nose and mouth to minimize how much unfiltered air gets entrained with the filtered output. But it is not meant as a 1:1 respirator replacement.

The Torch 2 injection molds are being made. This is the last 3D printed working model. There are just a few fiddly bits on the PCB we are finalizing.
Smol lady hands so hard to tell scale- it's a little chunky at 188mm x 60mm x 60mm but still much smaller than the original Torch kit.

Very cool design features in the updated Torch 2 Far UV light that can safely sanitize ambient air while being safe for people.
I like the removable battery and replaceable lamp, meaning that the lifespan of the Torch 2 is not limited to the life span of the lamp or the rechargeable batteries.

Another mask story.
A family boarded the flight, and as soon as they saw my mask they pulled their masks out and put them on.
Now mine was a respie of course… and they were using whatever they had, upon which I’m gonna chose not to pass judgement…

Masks work. I avoided getting covid from an infected service provider. We both mask but she's now upgraded from surgical masks to fitted respirators, like me! The hepa in her treatment room is now on high. She still tests & her family was able to avoid getting it from her as well.
