The protein in sea lettuce, a type of seaweed, is a promising complement to both meat and other current alternative protein sources. Seaweed also contains many other important nutrients, and is grown without needing to be watered, fertilised or sprayed with insecticides. However, the proteins are often tightly bound, and their full potential has not yet been realised on our plates.  But now researchers at Chalmers University of Technology, in Sweden, have found a new way to extract these proteins three times more efficiently than before – and this progress paves the way for seaweed burgers and protein smoothies from the sea.

X-rays are a common component of diagnostic testing and industrial monitoring, used for everything from monitoring your teeth to scanning your suitcase at the airport. But the high-energy rays also produce ionizing radiation, which can be dangerous after prolonged or excessive exposures. Now, researchers publishing in ACS Central Science have taken a step toward safer X-rays by creating a highly sensitive and foldable detector that produces good quality images with smaller dosages of the rays.

An international team of scientists has identified a surprising factor that accelerates the degradation of lithium-ion batteries leading to a steady loss of charge. This discovery provides a new understanding of battery life and offers strategies to combat self-discharge, which could improve performance in various applications from smartphones to electric vehicles.
