As a medical school professor, I used to tell students that attention lapses were just "brain fog." MIT's new Nature Neuroscience study reveals something far more profound. When you skip sleep, your brain forces emergency "wash cycles" during waking hours -- flooding cerebrospinal fluid through your skull to clear metabolic waste. The cost? Every wash cycle shuts down your attention for seconds at a time. Key findings from 26 adults studied with fMRI, EEG, and pupillometry: -- Sleep-deprived brains produced CSF waves identical to deep sleep -- 2 seconds before each attention lapse, fluid surged outward -- Brain activity dropped to sleep-like levels during waking hours Your brain will clean itself one way or another. Either you sleep, or it hijacks your waking hours to do it. Full breakdown coming on the Health Longevity Secrets podcast. #SleepScience #BrainHealth #Neuroscience #SleepDeprivation #Longevity Source: nature.com/articles/s4159…

Olivia doit son salut à une application nommée Aidy, codéveloppée par l'Institut Imagine, qui compare les clichés d’un patient à celles de dizaines de milliers d’enfants photographiés depuis 50 ans. Tous souffrent d’une maladie génétique, avec des malformations au visage. 4/10

MIT researchers have figured out why some cancer treatment drugs don’t work in all cases. Many tumors turn on a backup survival pathway that helps them keep growing when the targeted pathway is knocked out. news.mit.edu/2026/study-rev…

Du coup Trump dit : "je veux pas que les autres l'aient, ça m'emmerde". Donc on va la détruire. Plutôt que cette conversation embarrassante, on nous sert une "explication" : elle est vétuste faut la détruire. Hein ?! Bah pas vraiment, et où faire ces expériences en microgravité ?

Les expériences en microgravité ne se feront pas sur la Lune. Pourquoi détruire l'ISS comme on projette de le faire d'ici 4 ans ? Une explication peu glorieuse : projet jugé woke par Trump qui ne veut plus payer pour, Vladimir non plus : il a l'Ukraine à bombarder, ça coûte cher

Braelyn update Tuesday March 31st🤍 Today was Braelyn’s last day of home care. Tomorrow, we head for her proton radiation evaluation and additional imaging. Even after 2 years and 8 months, the days leading up to scans still bring a lot of anxiety. That part hasn’t gotten easier. But I find comfort in knowing the surgery was meticulous — Dr. Liau removed as much tumor as possible and cauterized the vessels feeding what remained. And we now have a clear plan forward: proton radiation, followed by DCVax. In the meantime, Braelyn keeps showing up and doing the work. She’s now walking independently and even going up stairs step-over-step without using the railing — something that felt impossible not long ago. Today we’re holding both things at once: the fear… and the progress One step at a time

@Nature @JD_Buenrostro @SNaga14 This connects well with epigenetic dysregulation that drives the aging process, subject of a new and topnotch review nature.com/articles/s4158… @gladyshev_lab

This same mechanism ties into the important @Nature report yesterday for how colitis can lead to colon cancer, well after inflammation has ended, but the transcription binding sites have been altered nature.com/articles/s4158… by @JD_Buenrostro @snaga14 and colleagues nature.com/articles/d4158…

I am dedicating this magnolia photo to all my friends who live with the knowledge that the next test could show their cancer is back or getting worse. Nobody knows the fear that walks with us. #fuckcancer 💙💙💙

Braelyn update Saturday, March 28th This is why we chose proton radiation for Braelyn. Photon radiation passes all the way through the brain — delivering dose before and after the tumor. Proton radiation can be targeted to stop at the tumor (Bragg peak), reducing exposure to surrounding healthy brain tissue. As we move into this next phase, I feel some relief knowing she will be receiving proton rather than photon radiation. This was not an easy decision for me. I have had significant concerns about radiation — especially to the brain — and still do. But this more targeted approach helps us balance two critical goals: • controlling tumor growth • preserving brain function and immune integrity That second part matters deeply right now. We are actively pursuing a dendritic cell vaccine, which depends on the body’s immune system to generate an effective response. We are trying to buy time — while also protecting the very system we hope will help her fight long-term. @andrewcaravello @NorthwestBio

Imagine if germline gene correction could become as routine--and affordable--as IVF. I talked to @CathyTie (Locke Bio, Manhattan Project) on Bio/Acc. How do we build in regulated biotech? Can D2C healthcare cut costs? And how do we do germline editing the right way? 🧵
