This appears to be due to Tachykin (Tk), specifically modulated by Acetobacter pomorum, acting on the cognate TK rcptr in the CNS. Further this microbiota-gut-neuron relay also appears to compromise gut barrier function in aged flies, indicating its role in determining health- as well as life -span.

Microbiota/gut/neuron axis promotes Drosophila ageing via Acetobacter, Tachykinin, and TkR99D Gut microbiota exert an evolutionarily conserved influence on ageing, from invertebrates to humans. How do microbes that are physically confined to the gut lumen affect the systemic physiological proc...

Excited to share the new preprint from the Dobson Lab -School of Molecular Biosciences University of Glasgow - demonstrating how a flies’ microbiota, compartmentalised to the gut lumen, can act to reduce lifespan, without affecting fertility/fecundity.

like sorry to go on about this (and it's obviously anecdotal!) but it feels mad and worrying to me that this mum nearly lost her son and her conclusion wasn't "I should have listened to doctors more" but "it's up to me to do more research" - that's not good! and she's probably not an exception!

Yesterday, Maurene Comey, who prosecuted the Epstein case, was summarily fired from SDNY. Her letter to colleagues pulls no punches. "Fear is the tool of a tyrant, wielded to suppress independent thought."

β€œThe connectome shows that LT52 is anatomically positioned to inhibit the neural networks involved in steering toward a visual object in the environment. Thus, we suggest that LT52 functions to prevent the fly from steering toward its own leg.”

nice 😁

'People think my wife is drunk but she's living with a rare brain disease' Edinburgh couple hope for treatment for rare neurological condition progressive supranuclear palsy.

See a lovely piece on STV highlighting the impacts of this disease on families . While our new findings will not lead to a new treatment today, we aim to bring hope to people living with PSP for the future news.stv.tv/east-central...

An important point to add here: science IS self-correcting. Many of the claims that were verified were verified by other researchers because they convincingly built on the original work. Likewise, many of the challenged claims were challenged in the published literature. Science works.

It is spectacular that here in the UK our society has become so miserly that we are genuinely talking about the possible arrival of people who literally saved the lives of tons of our literal brothers and sisters and uncles and aunts, as NATO soldiers in Afghanistan, in terms of it being a problem.

Different ways to die: harnessing variation in Drosophila reveals loss of tolerance and resistance over age and sex-specific association between infection susceptibility and lifespan It is widely accepted that susceptibility to infection increases with age. The reason often invoked is the dysregulation of the immune system, which is both cause and consequence of ageing. However, w...

⬆️ risk to die from infection predicts lifespan in males. Great group effort from the lab!

The Mandalorian (TV not film obvs) is the one that comes to mind first. I’d watch the whole credits just to listen to that Star Wars-like release!
As for movies though I’d prob go with a lot of Pixar. Inside Out, Up etc.
PTA’s Phantom Thread OST is also excellent and enhances what’s on screen πŸ‘Œ
