The perception of innocuous temperatures is crucial for thermoregulation. The TRP ion channels TRPV1 and TRPM2 have been implicated in warmth detection, yet their precise roles remain unclear. A key c...

Very interesting study by Lin Yuan & Co in the Julius lab, explaining how sensory neurons can adapt to exitotoxicity and calcium challenges e.g. by Trpv1 activation. Spoiler alert: the electron transport chain is involved - we enjoyed discussing it in Journal club.

On February 12, shortly before “High noon”, scientists at German research campuses, including here in Heidelberg, will stand up for Democracy: “facts, not fake news are needed for democracy”. See

– there is also find a Petition related to the cause. Get involved.

Just finished the book "Transformer" by Nick Lane, great inspiration to evolutionary biologists, bochemists and, yes, also neuroscientists - its all about transformation of organic molecules and energy flow and not (only) about genes. Highly recommended

Interesting thoughts on the type of biological problems AI research can help with, the complexity of biology that requires human intellect (and cannot be replaced by AI -- at least not currently, but I think it never will...), and human language that connects it all.

Many academics point to bioRxiv as “the one thing improving science publishing”. If so, the one thing you all can do is persuade colleagues to submit and make this a norm. 1/2
