In squamous cell carcinoma, a protein ensures that unneeded proteins are no longer disposed of. A research team at the University of Würzburg has switched off this protein for the first time. Squamous cell carcinoma is a very unusual type of cancer. They occur in many tissues – for example in the lungs, esophagus, pancreas, throat and pharynx, and on the skin.

The University of Zurich has sent adult human stem cells to the International Space Station (ISS). Researchers from UZH Space Hub will explore the production of human tissue in weightlessness. On 6 March at 11:50 PM EST, the International Space Station resupply mission Space X CRS-20 took off from Cape Canaveral (USA). On board: 250 test tubes from the University of Zurich containing adult human stem cells. These stem cells will develop into bone, cartilage and other organs during the month-long stay in space.

FRANKFURT. Even more detailed insights into the cell will be possible in future with the help of a new development in which Goethe University was involved: Together with scientists from Israel, the research group led by Professor Harald Schwalbe has succeeded in accelerating a hundred thousand-fold the nuclear magnetic resonance (NMR) method for investigating RNA. In the same way that a single piece of a puzzle fits into the whole, the molecule hypoxanthine binds to a ribonucleic acid (RNA) chain, which then changes its three-dimensional shape within a second and in so doing triggers new processes in the cell. Thanks to an improved method, researchers are now able to follow almost inconceivably tiny structural changes in cells as they progress – both in terms of time as well as space. The research group led by Professor Harald Schwalbe from the Center for Biomolecular Magnetic Resonance (BMRZ) at Goethe University has succeeded, together with researchers from Israel, in accelerating a hundred thousand-fold the nuclear magnetic resonance (NMR) method for investigating RNA.

Researchers from Dresden and Osaka present the first fully integrated flexible electronics made of magnetic sensors and organic circuits which opens the path towards the development of electronic skin. Human skin is a fascinating and multifunctional organ with unique properties originating from its flexible and compliant nature. It allows for interfacing with external physical environment through numerous receptors interconnected with the nervous system. Scientists have been trying to transfer these features to artificial skin for a long time, aiming at robotic applications.
