A recent study has stirred up a debate about saturated fats and their impact on heart health. The research, published in a medical journal, looked at 17 clinical trials involving over 66, 000 people. It found that cutting down on saturated fats can reduce the risk of heart attacks and strokes, but o
Our blood vessels have a special lining called the endothelium. Doctors can check how well this lining works by using a trick called flow-mediated dilation (FMD). When blood flow increases, it pushes against the vessel walls, and a healthy endothelium responds by widening the vessel. This widening i
Plastic pollution is a growing problem. Right now, a garbage truck's worth of plastic is dumped into the environment every second. That's a lot of waste. And it's only going to get worse. By 2040, plastic production is expected to increase by more than 50 percent. But waste management won't keep up.
Cancer treatment just got a boost with a new tool that combines imaging and therapy. This tool, called NO2/BDP-BT, is designed to target cancer cells precisely.

A rare guest from another star system is making a quick stop by Earth. This comet, named 3I/Atlas, is on a one-way trip through our solar system. It will be closest to our planet this week, but don't expect a close encounter. It's still very far away, about 167 million miles (269 million kilometers)
College expenses went up by 3. 6% in the 2025 fiscal year. This is a small increase from the 3. 4% rise in 2024, but less than the 4. 0% jump in 2023, when schools were dealing with the fallout from the COVID-19 pandemic. The Higher Education Price Index (HEPI) tracks these costs. It looks at the a
Radiation therapy (RT) is a common treatment for head and neck cancers. But it comes with risks. Studies show that RT can lead to problems with blood flow in the brain. These issues include narrowing of the carotid arteries, strokes, and temporary blockages. This review looked at many studies. It f
Stress is a part of life. But did you know it can mess with your heart? When someone is stressed, their body reacts in ways that aren't always good. One big problem is that stress can make blood vessels act up. And guess what? What you eat plays a role in this too. When people are stressed, they of
