Injuries to peripheral nerves – tissues that transmit bioelectrical signals from the brain to the rest of the body – often result in chronic pain, neurologic disorders, paralysis or disability. Now, researchers have developed a stretchable conductive hydrogel that could someday be used to repair these types of nerves when there’s damage. They report their results in ACS Nano.

Injuries in which a peripheral nerve has been completely severed, such as a deep cut from an accident, are difficult to treat...

Study suggests EMFs alter redox signaling to improve insulin sensitivity. Researchers from the University of Iowa may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes two major hallmarks of type 2 diabetes, according to new findings published Oct. 6 in Cell Metabolism.

“We’ve built a remote control to manage diabetes,” says Calvin Carter, PhD, one of the study’s lead authors and a postdoc in the lab of senior author Val Sheffield, MD, PhD, professor of pediatrics, and of ophthalmology and visual sciences at the UI Carver College of Medicine...

Chemistry experiments show potential to power fuel cells. Spinach, when converted from its leafy, edible form into carbon nanosheets, acts as a catalyst for an oxygen reduction reaction in fuel cells and metal-air batteries.

An oxygen reduction reaction is one of two reactions in fuel cells and metal-air batteries and is usually the slower one that limits the energy output of these devices. Researchers have long known that certain carbon materials can catalyze the reaction. But those carbon-based catalysts don’t always perform as good or better than the traditional platinum-based catalysts...

A strong, black coffee to wake you up after a bad night’s sleep could impair control of blood sugar levels, according to a new study.

Research from the Centre for Nutrition, Exercise & Metabolism at the University of Bath (UK) looked at the effect of broken sleep and morning coffee across a range of different metabolic markers.

Writing in the British Journal of Nutrition the scientists show that whilst one night of poor sleep has limited impact on our metabolism, drinking coffee as a way to perk you up from a slumber can have a negative effect on blood glucose (sugar) control.

Given the importance of keeping our blood sugar levels within a safe ra...
