Happy to have given a tiny contribution (as tiny as a fly brain!) to this new light-sheet microscopy technology.
Congratulations to @ld-light.bsky.social and the whole team
We demonstrate our method on biological samples with a range of RIs, including a whole fly brain 🧠 (imaged in < 3 min⚡) and > 1 cm long mouse bone 🐭🦴 (🧵 5/6).

Un nuovo studio condotto in D. melanogaster rivela che il bisogno di sonno potrebbe nascere direttamente dal metabolismo dei neuroni. Il sonno, insomma, sarebbe una conseguenza inevitabile della respirazione cellulare

www.scienzainrete.it/articolo/cos...
A cosa serve il sonno? La risposta può essere nel metabolismo neuronale
Perché dormiamo? La risposta a questa domanda rimane uno dei grandi misteri della biologia. Come scrisse il neurofisiologo Alan Rechtschaffen: «Se il sonno non avesse una funzione assolutamente vitale...

Tired? Well that sleepy feeling may be driven by 'leaky' mitochondria, according to a new study.

I spoke to Gero Miesenboeck from @ox.ac.uk for @nature.com all about the new study.

Mitochondria may have been labelled the "energy powerhouses" of cells, but they also seem to have an underappreciated role in sleep.
Our brain's mitochondria may play a crucial role in the onset of sleep
Textbooks say that mitochondria exist to supply cells with energy, but experiments in fruit flies suggest they are also involved in sleep

Thanks @dereklowe.bsky.social for featuring our work in @science.org blog "The Pipeline"
“Why do we sleep” has been a surprisingly hard question. But it looks like the answer may be “ Because we breathe”. Our mitochondria need a break!

Why academia is sleepwalking into self-destruction. My editorial @brain1878.bsky.social If you agree with the sentiments please repost. It's important for all our sakes to stop the madness

Honoured to be the guest on the 100th episode of the
@neuroversepod.bsky.social podcast!🎙️
With Clara Lenherr and @carolina-soares.bsky.social, I discussed the neurobiology of sleep—a topic that continues to fascinate and challenge us. Thank you to the Neuroverse team for inviting me.

Nature research paper: Sleep pressure accumulates in a voltage-gated lipid peroxidation memory

https://go.nature.com/4bG20He
Sleep pressure accumulates in a voltage-gated lipid peroxidation memory - Nature
Sleep-inducing neurons in Drosophila rely on Hyperkinetic, the β-subunit of the KV1 channel Shaker, to monitor sleep need by translating lipid peroxidation events into changes in the oxidation state of a stably bound NADPH cofactor.

Why do we need to sleep? In a preprint, researchers posit that it may be an "inescapable consequence" of how we power our cells. That and more of the best in Science and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪
