🔥 Super cool research in longevity by Shift Bioscience! A new preprint ("A single factor for safer cellular rejuvenation") from Shift Bioscience reports a striking finding: a single gene, SB000, achieves robust cellular rejuvenation across two germ layers—fibroblasts and keratinocytes—without inducing pluripotency. This could mark a meaningful step toward safer partial reprogramming. Using transcriptomic aging clocks, the authors show that SB000 reverses age-associated gene expression, reduces senescence markers, and maintains cell identity—outperforming OSK across dozens of epigenetic clocks, including Horvath and DunedinPACE. This matters. While OSK-based reprogramming has dominated the field, its translational barriers—tumorigenicity, dedifferentiation, and delivery—remain high. A factor that reverses biological age without disrupting cell function could change the game. But perhaps the deeper story here is how they got there. This discovery wasn’t driven by a one-at-a-time gene screen. It relied on a scalable, high-throughput computational pipeline—a blueprint for how AI-first biology can unlock novel rejuvenation strategies. This is exactly the promise of foundation models like scGPT: large-scale pretraining on single-cell atlases to learn the latent rules of gene regulation, cell state, and age progression. These models can predict perturbation effects, identify rejuvenation signatures, and even suggest interventions de novo. The convergence is clear: --AI enables global search over the gene regulatory space. A one-at-a-time gene screen didn’t drive this discovery --Foundation standards contextualize interventions across tissues, age, and health status. --Experimental biology validates, refines, and feeds back into the loop. Shift's SB000 is an exciting advance. But it’s also a case study of where aging research is going: from hypothesis-driven, to model-guided; from single-gene overexpression, to generative design grounded in cellular language. The future of aging is being written in code—both genetic and computational. Congratulations to the whole shift bio team! @lucascamillomd @dives86 @BrendanMSwain #AIinBiology #Longevity #Reprogramming #AgingResearch #scGPT #FoundationModels

The dream of waking up in the near future and being substantially younger at a cellular level is something I have the rare privilege to pursue each day. However, keeping this dream alive is contingent on the following (1) making timely and meaningful technical progress towards the end-goal (2) finding a spectacular short- and long-term commercial story, given the significant upfront time and capital investment required for drug development (3) nourishing the excitement and clarity of this mission, lest we settle for less on what will be a challenging journey. I’m excited to share technical progress that brings this dream a big step towards reality; a single gene sufficient for rejuvenation of multiple cell types, which unlike the Yamanaka factors, does not induce dangerous pluripotency pathways or threaten cell identity. Special mention to @lucascamillomd , @BrendanMSwain, @KMask94583 and Rihab (Raya) Gam , who played a disportionate role in this breakthrough along with the rest of the talented @ShiftBioscience team. Also a big thank you to @meltwindinvest, BGF, @FPrimeCapital, @Kindred_VC, @HealthspanCap , @KarlPfleger and our other investors for enabling us to directly pursue this mission.

Genuine epigenetic rejuvenation in primary cells has long been the holy grail. A groundbreaking preprint reveals that over-expression of a single (secret) gene overcomes this barrier: greatly reduced age estimates across in fibroblasts and keratinocytes according to validated epigenetic clocks including the Skin&Blood clock (Horvath 2018) and the original pan-tissue clock (Horvath 2013). In keratinocytes, this gene decreased the pan-tissue clock by nearly ten years for each month of treatment! Longitudinal sampling confirmed age REVERSAL. This gene seems to outperform even the Yamanaka factors (OSKM) while crucially avoiding pluripotency induction and its associated cancer risks.  Lucas Paulo de Lima Camillo,  Daniel Ives,  Brendan M.

The latest horrors out of Putin's war on Ukraine put the remaining Western holdouts against stronger action in an unbearable position. Excuses are now complicity, not prudence, not just cowardice.

109 kids. 109 kids have been killed by Russians since the day one of full-scale Russian invasion of Ukraine. Empty prams on Rynok Square today symbolize the lives of little angels. They are now defending Ukraine’sky instead of decisive actions of the world.

Ukrainian Foreign Minister Dmytro Kuleba warns NATO partners: "You can think as much as you want about how to avoid a direct confrontation with Russia, but if you do not help us to stop it now, a direct confrontation will be inevitable because you will be next."

Markhalivka village near Kyiv. Destroyed by Russian terrorists. At least 5 people are dead, 3 among them are children. These are the consequences of not closing the sky over Ukraine. Today this is a question of emergency. #ClosetheSkyoverUkraine

Our aces heroically defend our skies. But Russia has advantage. Dear partners who still have not provided Ukraine with military aircraft: how can you sleep when Ukrainian children are under bombs in Mariupol, Kherson, Kharkiv, other cities? You can take this decision now. Do it!

Barbaric Russian missile strikes on the central Freedom Square and residential districts of Kharkiv. Putin is unable to break Ukraine down. He commits more war crimes out of fury, murders innocent civilians. The world can and must do more. INCREASE PRESSURE, ISOLATE RUSSIA FULLY!
