The entrainment of theta brain waves with a commercially available device not only enhances theta wave activity but also boosts memory performance. That’s according to new research from the Center for Neuroscience at the University of California, Davis, published recently in the journal Cognitive Neuroscience.

MIT punches out cell-sized robots made of graphene
MIT researchers have developed a technique to mass produce cell–sized robots out of graphene(Credit: Felice Frankel) Robots are getting smaller and smaller, from the size of bugs down to tiny bead-shaped robots that could one day swim through the body to monitor health or deliver medication. MIT engineers recently managed to create cell–sized robots that could collect data about their environment, but were a little tricky to manufacture. Now, the team has found...

Paper-Based Smart Stickers for Implantable and Stick-On Diagnostics and Therapy
Flexible electronics make possible new wearable and implantable medical devices that conform to the body’s complex curvatures. While a great deal of progress has been made to make such technologies a reality, a lot of them are hard to manufacture, suffer from problems such as poor breathability, and don’t perform well inside the body. Now...

Amazon’s new patent will allow Alexa to detect a cough or a cold
Amazon is constantly trying to improve Alexa, its AI-assistant. A recent patent filed by the company shows just how: it wants Alexa to notice a user’s illness by detecting a change in their voice. Furthermore, it wants to suggest medicines or a recipe for chicken soup. But that’s not it. The patent suggests Amazon wants Alexa to detect more things: Emotional...

Intelligent patch warns of infected wounds
Infections in surgical wounds make up an estimated two per cent of all hospital expenses in Denmark. This corresponds to expenses of more than EUR 135 million (DKK 1 billion) per year. A new patch that automatically warns of infection may be one of several ways to reduce costs. A special sensor in the patient’s dressings notifies healthcare professionals if a...

A diagnostic tool to save lives and prevent brain damage
A new study confirms the efficacy of a new diagnostic tool that utilizes ultrasound to measure intracranial pressure following accidents. The technology will now be provided with artificial intelligence so that ambulance personnel can carry out examinations at accident scenes. Image: By examining the patient’s eye with ultrasound, doctors can reveal high brain pressure. In...

Stick-On Solar-Powered Heart Monitor Fits on a Finger
Scientists at the Riken, a major Japanese research institute, and University of Tokyo have developed a remarkable ambient light-powered cardiac monitor that looks like a transparent bandage. The underlying technology makes possible other flexible body-worn sensors that don’t need to have an external electric source powering them, including temperature and sweat sensors. Because power is...
