STOCKHOLM — American Karl Deisseroth and Germans Peter Hegemann and Georg Nagel won the 2026 Nobel Prize in Physiology or Medicine on Monday for their discoveries on light and optogenetics that have helped understand how the brain works. The Nobel Assembly of Sweden's Karolinska Institute medical university said Deisseroth, 54, Hegemann, 71, and Nagel, 73, were selected for their "discoveries concerning light-gated ion channels and optogenetics." Optogenetics "makes it possible to switch on, or off, the activity of individual nerve cells in a living brain," said Thomas Perlmann, Secretary-General of the Nobel Assembly at Karolinska Institutet. "This method is now being used in laboratories around the world to reveal the brain’s mysteries," Perlmann said. In clinical trials, researchers are restoring vision to people blinded by a condition called retinitis pigmentosa by inserting a light-sensitive protein in the retina. Researchers also hope optogenetics could improve cochlea implants,

Any sufficiently complex biological data that changes with age can be used to construct an aging clock. Here, researchers report on a clock derived from images of the nuclei of hematopoietic stem cells. Nuclear DNA exhibits structural changes in response to circumstances, regulated by epigenetic decorations to DNA and its supporting proteins, as regions unfold or are compacted. The structure of DNA determines which gene sequences are exposed to translation machinery, and thus whether or not a given gene is expressed. Some of these structural changes are characteristic of aging, and thus machine learning approaches should be able to visualize age-related differences in imaging. The functional decline of the hematopoietic system during aging affects organismal function and contributes to reduced healthspan. Quantifying hematopoietic aging holds […]

arXiv:2610.03593v1 Announce Type: cross Abstract: Quantum fire is a recently introduced cryptographic primitive consisting of efficiently preparable quantum states, called \emph{flames}, that admit efficient cloning but resist efficient telegraphing, namely reconstruction via classical communication without preshared entanglement. In all prior constructions of quantum fire, cloning is a public operation that requires no separate key and every holder of a flame state can clone it. For applications to access control, however, an issuer may wish to delegate cloning to designated quantum servers while withholding this capability from other flame holders. To address this, we introduce \emph{delegatable quantum fire}, in which cloning requires a separate key. We give two constructions in the classical-oracle model. Our first construction uses a classical secret key which enables cloning, and any user with the entire key may clone successfully. Our second construction, which we call

arXiv:2610.03537v1 Announce Type: new Abstract: Endovascular brain-computer interfaces (BCIs) avoid craniotomy but require precise device delivery through anatomically variable cerebral veins. This work presents the first demonstration of in vitro autonomous robotic navigation for endovascular BCI access in the cerebral venous system. Soft Actor-Critic controllers were trained in silico for two sequential tasks spanning the right internal jugular vein to the superior sagittal sinus, using geometric augmentation of one training anatomy. Navigation was evaluated in a training anatomy and an anatomically unseen hold-out model over 250 in silico episodes and five fluoroscopy-guided in vitro robotic runs per task-anatomy condition, comprising 1,000 simulated episodes and 20 physical runs overall. Task recurrent predictors were also evaluated for online identification of impending navigation failure. In silico success rates for Tasks A and B were 85.6% and 98.4% in the training anatomy and

arXiv:2610.02812v1 Announce Type: new Abstract: Young adults of color (YOC) face heightened mental health challenges and barriers to care while navigating developmental and life transitions. Situated between youth-oriented safeguards and adult-oriented AI systems, little is known about how they use AI chatbots for mental health and well-being support or how sociocultural contexts shape their expectations, concerns, and design preferences. We conducted a two-day co-design workshop with 13 Asian, Black, and Hispanic/Latino/a young adults aged 18--24. Participants found generic chatbot advice to flatten their lived experiences; rather than making incorrect assumptions, they wanted more opportunities for identity-informed disclosure. Preferences for YOC-centered personalization also revealed gaps in privacy and AI literacy. Participants negotiated different therapeutic roles for chatbots and sought greater AI accountability and user agency, highlighting blurred boundaries between clinical

arXiv:2610.02486v1 Announce Type: new Abstract: Typed decision models answer schema-constrained questions about a text in one forward pass and return probabilities meant to be thresholded. We ask whether biomedical sentence encoders trained for retrieval are good starting points for such models. We present SBERT2S1, which converts Sentence-Transformers encoders into bi-encoder, cross-head (C) and prior-fused residual (PFR) decision models, together with BIODECIDE, a biomedical typed-decision suite, and MEDLINE-S1, 243k training decisions derived from NLM indexing. Across six parent-retriever pairs, retrieval training improves zero-shot matching of content-bearing options. After fine-tuning, its effect depends on the head: across five pairs and three training-set sizes, retrieval training significantly helps PFR, which keeps the retrieval prior, in 10 of 15 comparisons, but helps C in one and hurts it in five. A matched grid of two heads and five training objectives shows that C

First generation stem cell therapies have become widespread; they are readily accessed in medical tourism clinics, and are also available for a range of issues in more regulated parts of the world. Initially it was hoped that transplanted cells would engraft and survive to assist tissues in repair and regeneration, but it has become clear that this is not how the therapies produce benefits. Rather it is a matter of signals generated by the transplanted cells in the short time they survive that beneficially alter the behavior of native cells. Unfortunately, while effects such as months-long suppression of chronic inflammation are fairly reliable, other hoped for improvements such as the stimulation of greater regeneration or regression of disease remain highly unreliable outcomes. One might ask […]

The commensal microbes of the gut microbiome generate a range of metabolites that are beneficial or necessary to cell function. Levels of a number of these metabolites have been shown to decline with age as the composition of the gut microbiome changes for the worse. Overall the gut microbiome clearly makes a meaningful contribution to health and longevity, as demonstrated by the sizeable benefits resulting from providing a young microbiome to an old animal, but it isn't clear as to how much of these effects derive from changes in the production of any specific metabolite. Metabolites produced by gut bacteria are taken up by the host and have a direct impact on its health. However, to our knowledge, no studies have investigated the effects of […]

Carotenoids are everywhere in our lives, even if most of us never notice them.

arXiv:2610.00441v1 Announce Type: cross Abstract: Secret sharing is ubiquitous throughout cryptography. All possible access structures are classically feasible, and in the case of threshold access structures, the protocols are even very efficient. However, when moving to the quantum setting, the no-cloning theorem shows that many access structures are impossible. In fact, no-cloning exactly characterizes feasibility: for thresholds, quantum secret sharing is possible if and only if the threshold $t$ is strictly more than $n/2$. In this work, we propose a variant of quantum secret sharing (QSS) where two or more identical copies of the input state are provided, but the output is only required to recover one copy. This notion circumvents the simple one-copy no-cloning obstruction, though the natural $k$-copy generalization still gives much milder obstructions. For thresholds using $k$ copies, no-cloning implies that QSS is impossible whenever $t\leq n/(k+1)$. It is tempting to
