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 […]

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 […]

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 […]
