A tiny new implant injected via a standard needle wirelessly regulates nerve signals — ending chronic pain without surgery, wires, or internal batteries. Developed by researchers at NYU Abu Dhabi and Cleveland Clinic Abu Dhabi, the miniature device—dubbed SEED (Stimulating Electrode for Electroceutical Delivery)—can be delivered through a standard medical needle. Positioned precisely near a targeted nerve using routine ultrasound or CT imaging, the seed-sized implant receives power wirelessly from a compact external transmitter. Once activated, it delivers soft electrical impulses that disrupt malfunctioning pain signals before they reach the brain, bypassing the need for invasive surgical procedures or internal battery packs. Traditional spinal stimulators require complex surgeries and carry risks of hardware infection, while oral painkillers often bring severe side effects and addiction risks. By offering a customizable, injectable alternative, this wireless electroceutical technology represents a major leap in non-surgical therapy for chronic pain, movement disorders, and paralysis. While currently in preclinical testing, it paves the way toward safer, on-demand relief that can be adjusted in real time by clinicians and patients alike. source: Ramadi, K., et al. (2026).

NASA's JWST confirmed the earliest supernova ever observed. The light came from a massive star that exploded when the universe was only 730 million years old. For the first time, the telescope also imaged the supernova's host galaxy.

A personalized mRNA vaccine cut the risk of melanoma coming back or death by 42% in a major trial. The trial, called INTerpath-001, enrolled 1,137 adults whose stage 2 to 4 melanoma had been surgically removed but who were at high risk of it coming back. All of them received pembrolizumab (Keytruda), a drug that helps the immune system attack cancer. About two-thirds also got the vaccine, which is made for each patient by reading the genetic code of their tumor and encoding up to 34 of its unique mutations in mRNA. That trains the immune system to hunt down any cancer cells left behind. After about two years, 82.2% of the vaccine group were still cancer-free, compared with 70.0% of those on the immunotherapy drug alone. Melanoma is the deadliest form of skin cancer, and this is the first time a personalized cancer vaccine has shown a clear benefit in a large, late-stage trial. The vaccine isn't approved yet, and it's too early to know if it helps people live longer, since survival data are still coming in. Side effects were mostly short-lived, like fever, sore arms and fatigue. source: Long, G. V., et al. (2026).

Low-dose aspirin slashed dementia risk by 70% in certain people, study shows. Researchers at Monash University in Australia went back to the ASPREE trial, a large study in which older adults took either a daily low-dose aspirin or a dummy pill (placebo). They analyzed the genetic data of more than 13,500 participants and gave each person a "polygenic score", a combined measure of many small gene variants, linked to how many platelets their blood makes. Platelets are the tiny cells that help blood clot. In the 20% of people with the highest platelet scores, just 1% of those on aspirin developed dementia, compared with 3.3% of those on placebo, about 70% lower risk. Earlier trials found aspirin didn't prevent dementia when everyone was considered together, so this points to a hidden group who might benefit, and to platelet biology as a new lead in dementia research. The signal wasn't tied to known Alzheimer's risk genes. But the same high-score group also had more major bleeding on aspirin, 4.4% vs 2.1% on placebo. This is a subgroup finding that still needs confirming in a dedicated trial. Do not start taking aspirin to prevent dementia on your own: daily aspirin can cause serious bleeding, so talk to your doctor first. source: Fransquet, P. D., Yu, C., Tran, C., Hussain, S.

Scientists watched the brain flip between a face it was seeing and a face it was hiding, about 15 times every second. Researchers at UC Berkeley, led by Janis Hesse and Doris Tsao, recorded thousands of individual neurons in two rhesus monkeys using ultra-thin electrode probes. The monkeys looked at a trick display: one face was shown to one eye, then a second face was flashed to the other eye. The flashed face is the one people consciously see, while the first is still there but pushed out of awareness. Instead of simply silencing the hidden face, the same face-sensitive cells in the temporal and frontal lobes alternated between the two, spending about 60 milliseconds on each before switching back. That matters because scientists have long hunted for a specific spot where consciousness lives. These results hint that timing, not just location, decides what reaches awareness: the brain keeps both options alive and rapidly picks which one gets the spotlight. It's an early preprint, not yet peer reviewed, based on two monkeys. source: Hesse, J. K., Lanfranchi, F. F., McGrory, C., Shi, Y., Engel, T. A., & Tsao, D. Y. (2026).
