Scientists have developed a new material that helps a costly catalyst survive for thousands of hours while producing hydrogen from water. The advance could address one of the problems holding back a promising method of making low-emission hydrogen. Researchers at Tohoku University designed a structure that keeps tiny particles of iridium firmly in place and […]

A new study suggests that hydrogen could be produced from natural gas while capturing most of the carbon dioxide generated during the process. In detailed computer models, some designs captured between 90% and 99% of those emissions. Researchers at the University of Manchester assessed a technology called chemical looping reforming. Their work, published in Carbon […]

The weakest part of a modern car’s digital security may sit outside the vehicle itself. A new study finds that more reported weaknesses now involve connected apps, websites and cloud services that handle information about drivers and their journeys. Researchers from the University of Gothenburg and Chalmers University of Technology examined 413 reported automotive software […]

Astronomers have found a rare view of a giant planet-forming disk that resembles a hamburger seen from the side. Its layered gas and dust may help explain how enormous planets begin forming far from their stars. The system, nicknamed Gomez’s Hamburger or GoHam, contains a young star surrounded by an unusually large disk. Because the […]

When a care home suffers a cyberattack, the problem is not limited to computers. Staff may lose access to important records while residents, families and partner organizations urgently need reliable information. A new communications toolkit aims to help adult social care providers prepare for these situations before they happen. Developed by Digital Care Hub with […]

The northern lights can spread across the sky like glowing curtains, but some of their smallest ripples remain difficult to explain. New research suggests that electrons bouncing against waves high above Earth may help create these delicate patterns. Scientists studied unusually detailed observations of an aurora and compared them with a mathematical model. Their results […]

A space telescope built to study distant galaxies has unexpectedly discovered a comet about 810 million miles from Earth. The find shows that even a mission looking far beyond our solar system can reveal previously unknown objects much closer to home. The European Space Agency’s Euclid telescope detected the comet in images collected between September […]

Scientists have identified a problem in the way brain cells remove damaged parts, offering another possible explanation for how Parkinson’s disease develops and why some patients later experience dementia. The research from the University of Copenhagen points to a failure in the system that clears damaged mitochondria. These tiny structures supply much of the energy […]

A hormone that helps the body manage salt and water may contribute to high blood pressure in more people than doctors once believed. Research suggests excess activity of aldosterone can be found across a wide range of blood-pressure levels. The finding matters because hormone-related hypertension may respond to treatments that target the underlying process. It […]

A photograph of a person’s face may contain clues about their health that go beyond their apparent age. Researchers have developed artificial intelligence tools that estimate biological aging and help predict survival among people with cancer. The findings do not mean a selfie can diagnose disease or predict an individual’s future with certainty. Instead, they […]

Millions of Americans live with high blood pressure, a condition that can quietly damage arteries and organs over time. Controlling it can involve medicines, exercise, weight management, and changes to what people eat. Sodium is one important part of the diet. Eating too much can raise blood pressure in many people, while potassium can help […]

A cold forecast could someday help hospitals and ambulance teams prepare for an increase in cardiac emergencies. New research from Hungary has found that changes in weather, especially lower temperatures, can help predict when more people than usual may suffer cardiac arrest outside a hospital. The nationwide study examined more than 114,000 cases recorded over […]

A pacemaker may have different implications for women and men after a common heart valve procedure, according to new research from Karl Landsteiner University of Health Sciences in Austria. The findings could help doctors provide more personalized care before and after treatment. The study focused on transcatheter aortic valve implantation, or TAVI. This procedure replaces […]

A rare immune disorder can cause swelling and lasting damage in organs throughout the body. In a new clinical trial, a drug called obexelimab helped more patients with the condition stay well after their symptoms had been brought under control. The condition, known as IgG4-related disease, can affect the pancreas, kidneys, salivary glands and other […]

Women with unusually enlarged breast tissue may face a higher likelihood of several health problems, including chronic migraine, neck pain and sleep apnea, according to new research. The condition, medically known as macromastia, is often discussed in terms of discomfort or appearance. However, researchers from Wake Forest University School of Medicine say it may be […]

Imagine trying to listen for a whisper while making a loud noise yourself. An African elephantnose fish faces a similar problem underwater. It sends out small electric pulses to explore its surroundings, but those pulses could drown out the faint signals it needs to detect food and other fish. The fish has sensors in its […]

Most galaxies have a massive black hole near their center. But some black holes may be far from the middle, drifting through the galaxy for billions of years. Astronomers say these wanderers could help answer a question about the early universe: how did the first black holes form? A black hole can begin to wander […]

Heart and blood vessel diseases are common in people living with Alzheimer’s disease and Parkinson’s disease. Many of these patients take medicines for conditions such as high blood pressure, heart failure or an irregular heartbeat, so doctors need to regularly consider whether each medicine remains helpful as the disease progresses. New doctoral research from the […]

Regular aerobic exercise is one of the most effective ways to protect the heart. Activities such as brisk walking, cycling, swimming and running make the heart beat faster and help the cardiovascular system work more efficiently. Over time, aerobic activity can help lower blood pressure, improve cholesterol levels and support healthy blood sugar control. It […]

As we grow older, some cells stop dividing but remain in the body. Scientists call them senescent cells. They are sometimes nicknamed “zombie cells” because they are still alive, even though they no longer make new cells. These cells are part of normal life. They can help during early development and tissue repair. But when […]
