Biophysics: Stretching proteins with magnetic tweezers

As the central mediators of cell function in biological organisms, proteins are involved in the execution of virtually all cellular processes. They provide the internal scaffolding that gives cells their form, and enable cells to dynamically alter their morphology. They transport substrates back and forth across membranes, and they catalyze…

From Japanese basket weaving art to nanotechnology with ion beams: Ultradense arrays of magnetic quanta in high-temperature superconductors

The properties of high-temperature superconductors can be tailored by the introduction of artificial defects. An international research team around physicist Wolfgang Lang at the University of Vienna has succeeded in producing the world’s densest complex nano arrays for anchoring flux quanta, the fluxons. This was achieved by irradiating the superconductor…

Cardiac device complications vary widely among hospitals

The chances of patients experiencing complications after having a cardiac device implanted vary according to where they have the procedure. A study of 174 hospitals in Australia and New Zealand published today in the Annals of Internal Medicine shows that the quality of care people receive may account for the…

First birth after robot-assisted uterus transplant

A boy 48 centimeters long, weighing 2900 grams, is the first baby born after the technological shift in Gothenburg’s world-leading research on uterine transplantation. The birth, with the planned cesarean delivery (C-section), took place on Monday April 8th and the whole family is doing fine. “It’s a fantastic feeling to…
