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 […]

Scientists have developed a low-cost device that can continuously check air ducts at nuclear facilities for traces of radioactive material. The detector, created at the U.S. Department of Energy’s Oak Ridge National Laboratory, or ORNL, can take measurements once a minute when running on a battery. When connected through an Ethernet cable, it can collect […]

Scientists have discovered that the weather on a distant world may be far more organized than it first appears. The object, known as SIMP 0136, is a brown dwarf located about 20 light-years from Earth. It is larger and hotter than a gas giant planet such as Jupiter, but it is not massive enough to […]

Networks shape much of the world around us. Friendships form social networks, computers connect through the internet, brain regions communicate with one another, and countries are linked through trade. However, scientists often face two major difficulties when studying these systems. They may see only part of a network, and they must decide whether an apparent […]

Scientists have developed a new way to make an extremely strong metal-based material much less likely to break when it is bent or squeezed. The discovery could eventually lead to tougher materials for aircraft engines, turbines, energy systems and other machines that operate under extreme conditions. The research was led by engineers at Purdue University […]

Quantum computers promise to solve some problems that are extremely difficult for today’s computers. But there is a major obstacle: quantum information is very fragile, and even tiny disturbances can cause a calculation to go wrong. Researchers at Chalmers University of Technology in Sweden have now proposed a way to perform a wide range of […]

A tiny crocodile relative that lived about 125 million years ago has given scientists an unusually detailed look at what ancient reptiles may have looked like. A remarkably preserved fossil from northeastern Spain contains traces of skin, soft body parts and even a possible pattern of light and dark bands on its tail. The animal, […]

Social media began as a simple way to keep in touch with friends and family. Today, many people can spend hours moving through an almost endless stream of videos, photographs, opinions and recommendations from people they have never met. A major new analysis suggests this change may have consequences for mental health. Researchers found that […]

A night’s sleep may seem like a quiet break from the day, but the brain remains busy. While we sleep, it sorts through new information, strengthens some memories and prepares us to learn again when we wake up. That nighttime work becomes especially important as people get older. Many older adults notice that the small […]

Semaglutide is best known as the active ingredient in the diabetes drug Ozempic and the weight-loss drug Wegovy. It belongs to a group of medicines called GLP-1 drugs, which can reduce appetite, improve blood sugar control and help people lose weight. New animal research suggests the drug may also affect some of the biological changes […]

Scientists searching for ways to protect the aging brain have turned to an unusual source: sea squirts. A study in aged mice found that supplements rich in plasmalogens, molecules found in these marine animals and in the human body, were linked with better learning, healthier brain connections and lower brain inflammation. The findings sound dramatic, […]
