Cyanobacteria – which, like plants, #photosynthesise and convert carbon dioxide (CO₂) into sugar and oxygen – have to cope with widely varying CO₂ concentrations in their surroundings. Now, researchers have mapped the mechanism behind this. The discovery could eventually change

Seemingly healthy people can collapse without warning when the heart’s rhythm suddenly breaks down. Now, a landmark study in Denmark shows that increasing the body’s potassium level slightly, can cut the risk of life-threatening arrhythmia among the most vulnerable people with

For decades, doctors have puzzled over why some gut #bacteria outlast powerful #antibiotics. Now a miniature laboratory that recreates the oxygen-free world of the intestine lets researchers watch gut bacteria in their natural element and could help unravel many more #health

Although conditions such as attention-deficit/hyperactivity disorder (#ADHD) or #schizophrenia only appear later in life, a new study shows that the seeds are often sown during #pregnancy. The researchers suggest that screening for #genetic predisposition could enable

What if #cancer drugs could be custom-built to match each person’s #tumour – and be ready in weeks instead of years? By designing precision #molecules on a computer, scientists are teaching immune cells to attack cancer without harming healthy tissue. This is a new kind of

Four in 10 people who have survived #cancer still battle exhaustion, pain or sleep problems – even years after their #treatment has ended according to a new nationwide study from the Danish Cancer Institute that found major social differences in who is affected. #sciencenewsdk

Researchers used #genetic #data from more than 5 million people to develop a new score that helps to explain why some gain #weight rapidly whereas others do not. The findings bring us closer to identifying – already in #childhood – who is at greatest risk of developing #obesity

Long before blood sugar rises, a silent defect in muscle starts to reshape the body from within – feeding heart #disease, fatty liver, #cancer and #Alzheimer’s disease. Gerald Shulman spent decades tracking that defect to fat being in the wrong place, challenging long-held

A natural substance present in the human body has been transformed into a new contrast agent for magnetic resonance imaging (#MRI). With a single dose, researchers can monitor both rapid blood flow and slower distribution in #organs. The result: gentler and more detailed #scans,

Rechargeable #batteries can now be made without rare #metals, making them greener. But that very progress makes #recycling more difficult and the waste problem is piling up. Now, a study shows that improving #wastemanagement may make recycling profitable. #sciencenewsdk

In June 2025, Denmark became the first European Union country to ban 23 #pesticide products because of their content of per- and polyfluoroalkyl substances (#PFAS) and the risk they pose to drinking-water and human #health. More countries are expected to follow. And with the

A new study from Denmark shows that #gutsymptoms are widespread – even among people that seem very healthy. The findings challenge the idea that such symptoms always signal #disease and may lead to clearer guidelines on when they require attention. #sciencenewsdk Read more:

Researchers have designed an #algorithm that can predict how good a white #wine tastes by analysing its chemical components. The tool could help #winemakers craft better wines – including alcohol-free versions people actually want to drink. #sciencenewsdk @BQuintanillaC Read

Scientists restored brain function in mice with Huntington’s #disease by fixing glial #cells – the brain’s overlooked helpers. Instead of repairing neurons, they healed the support system that keeps #neurons alive, opening a new path for treating neurodegeneration.

For the first time, researchers have uncovered concrete #genetic traces of obsessive-compulsive disorder (#OCD) in human #DNA, bringing us closer to a biological understanding of the #disorder. #sciencenewsdk Read more: https://t.co/Gh6m0Sxqnb

Millions live with type 2 #diabetes – nevertheless, hidden in their muscles, lies a key. Researchers have found an alternative route for #glucose uptake in the muscles that works even when #insulin fails – and that could pave the way for entirely new treatments. #sciencenewsdk

On World Heart Day, we are reminded of the importance of understanding and protecting our hearts and new research shows just how vital that knowledge can be. A major new study reveals that two different types of heart attack may actually require the same treatment approach,

Even the most strongly hereditary mental #illnesses, such as #schizophrenia and #bipolar disorder, are rarely passed directly from parent to child. Most cases appear to arise out of the blue – not from a single faulty gene but from thousands of #genetic variants scattered across

The microbes clinging to each grain of sand explain why sand plays such a key role in the ocean’s #nitrogen cycle. As more and more nitrogen pours into the world’s #oceans, understanding how microbes remove it - and how much they can process - is crucial, says a researcher.
