Casey Harrell was losing his ability to speak due to amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease.

“Not being able to communicate is so frustrating and demoralizing. It is like you are trapped,” said Harrell, 45.

But a new brain-computer interface is allowing Harrell to speak to others once more, with his brain providing the words and a ...

A wearable brain scanner could improve research into Parkinson’s disease, dementia and other debilitating disorders, new research shows.

The brain scanner -- called the Ambulatory Motion-enabling PET (AMPET) -- fits on a person’s head much like a construction worker’s har...

Newly developed battery-powered electric bandages could help wounds heal more quickly, a new study reports.

In animal testing, wounds treated with electric bandages healed 30% faster than wounds treated with conventional bandages, researchers reported Aug. 7 in the journal Science Advances.

The bandages could...

Abbott has warned diabetes patients that some of its continuous blood sugar monitoring systems may need to be replaced because of inaccurate readings.

"Abbott has recently identified a small number of FreeStyle Libre 3 sensors that may provide incorrect high glucose readings, which if undetected may pose a potential health risk for people living with diabetes," the company said in an

"Smart"prosthetic legs can help amputees achieve a natural walking gait, but it's done through robotic sensors and algorithms that drive the limb forward at predetermined rates.

A better way would be to give people full control over the limb through their nervous system -- and that's just what an MIT research team says it's done.

An experimental surgical procedure combined with a cu...

Scientists have developed microscopic robots capable of swimming through the lungs to deliver chemotherapy directly to lung cancer cells.

In early testing, these microbots  extended the average survival time of lab mice with melanoma that had spread to the lungs, according to a report publis...

California skateboarder Jared Hager has become the first person to receive a transparent skull replacement, which allows doctors to better view the function of his brain.

The window has allowed doctors to both monitor his progress and test new and better scanning methods for assessing brain health.

Hager, 39, of Downey, Calif., sustained a traumatic brain injury from a skateboarding...

A "Third Thumb"-- a robotic, prosthetic extra thumb -- is easy to use and can help folks grab and tote more objects, a new study says.

Hundreds of diverse test subjects at a science exhibition were able to figure out the extra thumb quickly and use it to pick up things like pegs and foam objects, researchers reported May 29 in the journal Science Robotics.

"Technology is ch...

If you use a medical device such as a blood glucose monitor or insulin pump, keeping it charged is a must. 

But devices that rely on a USB charger can overheat, which may cause minor injuries, serious burns or fires. That's why it's important to read, understand and follow the manufacturer's use and care directions and use only approved charging accessories.

The U.S. Food and D...

The U.S. Food and Drug Administration has issued a Class 1 recall -- its most urgent kind -- for an IOS app linked to a specific kind of insulin pump used by people with diabetes.
