While cutting back on salt intake has long been a mainstay in treating high blood pressure, new research suggests that upping potassium intake might have a greater effect. It might be time to stock up on bananas, apricots, and sweet potatoes.

Wearable health-monitors are everywhere, from Fitbits for the health conscious to continuous glucose monitors for diabetics, but most are limited in what they can tell us, and there are issues around accuracy, calibration and reliability. Researchers in Sweden are working to change that.

Engineers at Penn State University have produced an ammonia-based battery that not only captures and converts waste heat into electricity economically and efficiently, but is also claimed to do so at a greater power capacity than other similar systems.

A team of researchers is seeking to challenge the theory that the anode, cathode and electrolyte of a battery can only work independently, experimenting with a dual functioning electrolyte that supplements the cathode, resulting in a significant improvement of the battery's capacity and lifespan.

Beer is often quaffed in the aftermath of a day of sports, despite the ill effects resulting from dehydration. However, a group of Australian Public Health researchers have now found that the bad effects of alcohol can be eased by adding a pinch of sodium to your beer.
