Engineers at the Johns Hopkins Urology Robotics Lab report the invention of a motor without metal or electricity that can safely power remote-controlled robotic medical devices used for cancer biopsies and therapies guided by magnetic resonance imaging.

Researchers developing a system that uses mathematical models and sensors to locate passengers releasing hazardous materials or pathogens inside airline cabins have shown that the technique can track a substance to an area the size of a single seat.

Peering into the body and visualizing its molecular secrets, once the stuff of science fiction, is one step closer to reality with a study from researchers at the Stanford University School of Medicine.

A nanocomposite particle can be constructed so that it has a mix of properties that would not otherwise happen in nature. By combining an organic matrix with metallic clusters that can absorb light, it is possible to incorporate such particles into cells

In the first method, developed at the University of Miami, researchers show how magnetic nanoparticles (MNPs) may be used to create mechanical tension that stimulates the growth and elongation of axons of the central nervous system neurons.

Endotoxin, a toxic substance made by certain types of bacteria, may reduce the risk of developing the allergic skin condition eczema or wheezing in children if they are exposed to it up to age 3, suggests a new study.

UT Southwestern Medical Center has joined a national clinical trial to identify the long-term health effects of West Nile virus infection and to learn more about the disease's progression, symptoms and mortality.

It turns out Mom was right – you should eat your broccoli. But what Mom may not have known is why broccoli is so healthy, and how its lesser known, younger offshoot may be a powerful anti-cancer agent.

Anyone who has experienced chronic pain knows that it affects the ability to work, sleep and perform other activities essential to leading a full life.

Circadian clocks regulate the timing of biological functions in almost all higher organisms. Anyone who has flown through several time zones knows the jet lag that can result when this timing is disrupted.
