One of the dangerous things about sports-related concussions is the fact that athletes may not realize they have one, so they don't seek medical attention. A new sensor could let them know, and it would go on their neck, not their head.

Cardiovascular diseases are the leading cause of death worldwide, but numbers could be reduced with better early warning systems. A new study has outlined just such a system, using nanoparticles that make atherosclerotic plaques emit ultrasound waves.

Chronic wounds can be very difficult to treat, potentially leading to amputations or even death due to associated infections. A new dressing, however, may be able to heal such wounds while remaining much less expensive than other materials.

The skin is the body’s first line of defense against infection, and new research has brought us closer to understanding how it works. Researchers at Yale have identified how immune cells spread themselves out to maintain the most effective patrol.

The ingenuity of bacteria keeps surprising scientists. The latest example is a species called Geobacter sulfurreducens, which has now been found to survive exposure to toxic cobalt by building a metal “suit” like a tiny little Iron Man.

Engineers at Michigan State University have crafted a new type of liquid foam lining they say can help football helmets better sustain repeated impacts, improving their longevity and the safety of those wearing them.

Scientists have created the first-ever functional miniature human hearts in the lab. Grown from stem cells, these heart “organoids” are made up of all primary heart cell types, and could help build better models for treating disease.

A study is offering more evidence that placebo drugs can still work even when people are aware they are taking inactive pills. The research builds on a growing body of study suggesting “honest” placebos could have a role in modern clinical practice.

Generally speaking, robotic "hands" vary between rigid devices with a firm grasp, and softer, gentler gadgets that are a bit wimpier. Now, however, scientists have created an appendage that they claim combines the best features of both.

When it comes to putting out forest fires, the sooner that they're detected, the better. That's where a new forest-deployed sensor could come in, as it's powered by swaying tree branches.

We've seen flexible supercapacitor designs before, but how about one that's stretchable? A new discovery by researchers at Duke University and Michigan State University could lead to an excellent stretchable power source for wearable electronics.

Atherosclerotic plaque-deposits on the inner walls of arteries are a frequent cause of heart attacks and strokes. A newly-developed nanoparticle could help minimize those deposits, as it prompts the body's own cells to "eat" them.
