Researchers wake up silent, healthy genes in Prader-Willi syndrome
In Prader-Willi syndrome a group of genes does not work, even though every cell has a healthy back-up copy. Researchers in Melbourne switched that copy back on by removing one protein, in patient cells and in mice. Work on a medicine is now under way.

AI finds hidden DNA error that standard software missed for years
An AI system from the American company Gamow Labs found the hereditary cause of a rare lung disease in a baby who died. Ordinary software had filtered the error out. A lab confirmed the finding, and the parents now know where they stand.

AI estimates biological age and cancer survival chances from a single face photo
Researchers at Mass General Brigham built AI that estimates, from a single ordinary face photo, how old someone's body is and how likely a cancer patient is to survive. This could help doctors better assess how much treatment a patient can take. Further research is needed first.

Magnetic brain treatment tuned to the patient's own rhythm cleared for PTSD
In the US, a PTSD treatment has been cleared that tunes magnetic pulses to the patient's own brain rhythm. In a trial with 158 adults it worked better than a sham treatment, without serious side effects. A scientific publication is still to follow.

Wafer-thin mesh draws electricity from beating human heart cells
Researchers in the US grew beating human heart tissue around a wafer-thin mesh that generates a little electricity with every heartbeat. The work has so far been done in the lab. The goal: implants such as pacemakers that no longer need a battery.

Low-power brain implant recognises mental state from how brain regions work together
Researchers at EPFL have built a chip of 4 by 2 millimetres that measures how brain regions work together and so recognises concentration and emotional arousal. It uses very little power. The chip already works on recordings from people and in rats; patients are the next step.

Personalised mRNA vaccine cuts the risk of melanoma returning by 42 per cent
A vaccine made to measure for each patient cut the risk of recurrence or death by 42 per cent in a large study of 1,137 people with melanoma. The full results have now been presented at the European cancer congress ESMO.

Microsoft AI finds the right diagnosis more often than general practitioners in a simulation
According to a Microsoft study in the journal Science, the AI system MAI-DxO found the right diagnosis in 83 per cent of difficult cases, compared with 36 per cent for doctors. A test with real patients comes next.

Hugging Face releases open AI model that lets researchers 'talk' to DNA
With Hugging Face's Carbon-X, researchers paste a piece of DNA into a chat and ask in plain language whether a change is likely to be harmful. The model is free and runs on a researcher's own computer. It is meant for research; the next step is testing in the lab.

10-dollar light sensor from Cambridge can recognise substances in skin, food and plastic
Researchers at the University of Cambridge made a spectrometer on a chip of a few centimetres, for about 10 dollars. It recognises substances by the light they absorb. In one volunteer it tracked blood sugar without a finger prick; the next step is testing in more people.

Precise DNA correction used inside a patient's body for the first time
Prime Medicine has for the first time treated a patient with prime editing directly inside the body. A single infusion is meant to repair a DNA error in the liver in Wilson's disease, an inherited copper disorder. The study has just begun; first results are expected in 2027.

Breakthrough in hepatitis B: first medicine that lets 1 in 5 patients stop taking pills
In the United States, a medicine has now been approved that can 'functionally' cure chronic hepatitis B in some patients. After six months of injections, the virus stayed under control in about 1 in 5 participants, even when they stopped all medication.

Claude designs proteins against scorpion venom in 64 hours: 17 bind to their target in the lab
A research version of Claude designed over 318,000 small proteins against five scorpion toxins in 64 hours. Two labs made 211 of them, and 17 bound firmly to their toxin. It is not yet an antidote, but it is a first step.

MIT researchers' glue sticks to wet tissue in seconds and could soon replace stitches
The company SanaHeal, an MIT spinout, makes a glue that sticks to wet and bleeding tissue within a few seconds. According to MIT it is already approved for stopping bleeding after accidents. Next year, trials in people during surgery will begin.

Antibody keeps immune cells out of the brain and slows Alzheimer's damage in mice
Researchers in St. Louis blocked the route immune cells take into the brain in mice. The mice kept about 40 per cent more brain tissue and remembered better, while the harmful protein tau simply stayed in place. The next step is finding out whether this can be done safely in people.
