New preprint:
There are some decent tools for multi-animal tracking, but it can still be difficult to track interacting animals without mixing them up. Isaac Robinson (with @wheelerlab.org and others) have developed a software solution that we are now using full time: doi.org/10.1101/2025...

More biomed in Canada
I mentioned to a couple of people that I had a surprise waiting to be shared when Moderna got approval for its updated COVID-19 vaccine. It’s approved, and the big news??? Completely produced domestically!!!!! 🥳🤩
Approved as usual for all aged 6mo+!

Lemborexant ameliorates tau-mediated sleep loss and neurodegeneration in males in a mouse model of tauopathy - Nature Neuroscience
Parhizkar et al. show that lemborexant, an orexin receptor antagonist, protects against neurodegeneration in male tau transgenic mice by preventing tau protein build-up and inflammation, highlighting ...

I appreciate the debates about machine intelligence, and how LLMs are forcing us to review our constructs. But I also think it's fun to think of LLMs as a mirror we've put in front of animals that don't have a concept of mirrors (image from @theonion.com)

@neuroai.bsky.social : years ago you tweeted about a thought expmnt that toyed with whether a conscious system depends on connections (like "lab records brain, also stimulates unconnected cells in synchrony w/recording--is the collection of cells conscious?") Do you know where this is published?

1. Imagine we land a space probe on one of Jupiters’ moons, take up a sample of material, and find it is full of organic molecules. How can we tell whether those molecules are just randomly assembled goo or the outcome of some evolutionary process taking place there? 🧪

Best part of the Lumen festival in Waterloo was the photonics. I wouldn't call the installations controversial, but some were definitely polarizing.
