New catalyst efficiently produces hydrogen from seawater

Seawater is one of the most abundant resources on earth, offering promise both as a source of hydrogen and of drinking water in arid climates. Now researchers have reported a significant breakthrough with a new oxygen evolution reaction catalyst that, combined with a hydrogen evolution reaction catalyst, achieved current densities capable of supporting industrial demands while requiring relatively...

Injectable, flexible electrode could replace rigid nerve-stimulating implants

By electrically stimulating nerves, neuromodulation therapies can reduce epileptic seizures, soothe chronic pain, and treat depression and a host of other health conditions without the use of conventional drugs like opioids. Now, biomedical engineers have made a significant advance that could dramatically reduce the cost of neuromodulation therapy, increase its reliability and make it much less...

What do we know about the gut microbiota in Parkinson's disease?

Since the discovery that the gut microbiome may play a role in the development of Parkinson's disease (PD), this fresh scientific approach has produced varying results. Scientists compare results of current research and provide recommendations to increase the comparability and utility of these studies with a view towards improving patient outcomes.
