Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to lose function and die over the following days—has remained one of the most important unanswered ...

Most people know about "good" and "bad" cholesterol. But few realize there is another type called lipoprotein(a). It can raise the risk of heart attacks and strokes, even in people who do everything right.

An AI model (REDMOD) can pick up the very early subtle tissue changes of pancreatic ductal adenocarcinoma, the most common form of pancreatic cancer, which conventional imaging and the human eye find difficult to detect, ...

As devices for wireless sensing systems become smaller and more complex, finding suitable power sources for them is becoming increasingly difficult. However, advances in low-power sensing technology may allow such systems ...

Under a microscope, a bouquet of lollipop-like structures, each smaller than a grain of sand, waves gently in a Petri dish of liquid. Suddenly, they snap together, like the jaws of a Venus flytrap, as a scientist waves a ...

A first-of-its-kind pilot program in Utah developed by a health-technology startup company uses artificial intelligence to automatically renew certain prescriptions for patients with chronic conditions such as hypertension ...

Researchers at McGill University have developed a rapid way to engineer blood clots that stop severe bleeding and support tissue healing more effectively. Their technique, called "click clotting," links red blood cell surface ...

After nearly four decades, the world's longest-running soil warming experiment is revealing a surprising result: even "stable" carbon in forest soils can break down as temperatures rise, releasing more CO₂ into the atmosphere. ...

Atmospheric dust plays a dual role in Earth's climate: it reflects some sunlight back into space while also absorbing and retaining the planet's heat like an insulating blanket. But while dust likely cools the planet overall, ...

Researchers including a number from the University of Exeter, have identified the most urgent unanswered questions about peatlands, providing a global roadmap to guide future science and policy for one of the planet's most ...

You've probably seen it on social media before: a paragraph of scrambled text that looks like nonsense at first glance, yet somehow you can read it with surprising ease.

Our sun is a bit of an outlier in the general stellar population. We typically think of stars as being solitary wanderers throughout the galaxy. But roughly half of sun-like stars are locked in with more than one companion ...
