Unique insight into the inner workings of our cellular powerplants

Using advanced microscopy techniques, researchers at Karolinska Institutet and Stockholm University have visualized in unprecedented detail the machinery that the cells’ powerhouses, the mitochondria, use to form their proteins. The results, which are published in Nature, raise hopes of more specific antibiotics and new cancer drugs in the future.
