Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the tip of a syringe—and be noninvasively injected into the body.

Over the past decade, 3D printing has gone from being a futuristic idea to a revolutionary tool. In medicine, its ability to produce custom-made, complex structures is changing the way doctors treat injuries and diseases—especially ...

The sugar glucose, which is the main source of energy in almost every living cell, has been revealed in a Stanford Medicine study to also be a master regulator of tissue differentiation—the process by which stem cells give ...

The cells in human bodies are subject to both chemical and mechanical forces. But until recently, scientists have not understood much about how to manipulate the mechanical side of that equation. That's about to change.

A study led by bioengineers at the University of California San Diego sheds new light on how a type of heart valve disease, called aortic valve stenosis, progresses differently in males and females. The research reveals that ...

How does the armored tiling on shark and ray cartilage maintain a continuous covering as the animals' skeletons expand during growth?

Imagine a world where bacteria, typically feared for causing disease, are turned into powerful weapons against cancer. That's exactly what some scientists are working on. And they are beginning to unravel the mechanisms for ...

Johns Hopkins University engineers have developed a pioneering prosthetic hand that can grip plush toys, water bottles, and other everyday objects like a human, carefully conforming and adjusting its grasp to avoid damaging ...

Xolography is a novel light printing technique that has been explored for dental products and in-space manufacturing. At Eindhoven University of Technology (TU/e), this technique has now been adapted to 3D print living cells. ...

New technology developed by researchers at the University of Houston could revolutionize medical imaging and lead to faster, more precise and more cost-effective alternatives to traditional diagnostic methods.

The brain may play a role in helping the ear regulate its sensitivity to sound and compensate for hearing loss by sending a signal to a structure in the inner ear known as the cochlea, according to a study that was published ...

Apical periodontitis, a chronic and hard-to-treat dental infection, affects more than half of the population worldwide and is the leading cause of tooth loss. Root canal is the standard treatment, but existing approaches ...
