Researchers have developed a mathematical model that can predict the optimum exercise regime for building muscle.

The miniaturization of microelectronic sensor technology, microelectronic robots or intravascular implants is progressing rapidly. However, it also poses major challenges for research. One of the biggest is the development of tiny but efficient energy storage devices that enable the operation of autonomously working microsystems -- in more and more smaller areas of the human body for example. In addition, these energy storage devices must be bio-compatible if they are to be used in the body at all. Now there is a prototype that combines these essential properties.

Researchers have developed a new light-emitting memory device by integrating a resistive random-access memory with a light-emitting electrochemical cell that are both based on perovskite. The results are promising for faster data storage and reading in future electronic devices and open a new avenue of applications for perovskite optoelectronics.

Researchers have devised a method for measuring the high-spin state of up to four electrons confined on a tiny gallium arsenide quantum dot. This research may lead to quantum computers that can process information by manipulating both electron charge and spin.
