A group of researchers at Karolinska Institutet and the Max Planck Institute for Biology of Ageing has discovered that a protein called MTERF4 combines with another protein called NSUN4 to form a complex that controls the formation and function of the mitochondrial ribosomes. In mice lacking MTERF4 no functional ribosomes are formed, leading to a reduction in energy production.
"Reduced mitochondrial function is involved in several inherited diseases, normal ageing and age-related diseases," says Professor Nils Göran Larsson, who co-led the study with Professor Claes Gustafsson. "Fundamental knowledge of how mitochondrial function is regulated can therefore be of great clinical significance in the future."
The research group previously discovered similar regulation mechanisms in the mitochondria that were found to be related to the development of diabetes.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
