SARS-CoV-2: no virus detection in the blood of asymptomatic patients


The Paul-Ehrlich-Institut in cooperation with three institutes of virology, has evaluated laboratory data of SARS-CoV-2 infected persons. No SARS-CoV-2 genome could be detected in the blood of asymptomatic patients or in patients with less pronounced symptoms.

Non-invasive method to predict brain pressure


The only way to accurately measure pressure inside the skull is to insert a catheter or sensor inside. However, this is invasive and techniques with less risk are desired. Intracranial pressure (ICP) needs to be correctly accounted for in a variety of medical situations including neurosurgery, neurology and emergency medicine.

Printing complex cellulose-based objects


Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3D printed complex objects with higher cellulose content than that of any other additively manufactured cellulose-​based parts. To achieve this, they used a clever trick.

Engineers find ankle exoskeleton aids running


Running is great exercise but not everyone feels great doing it. In hopes of boosting physical activity - and possibly creating a new mode of transportation - engineers at Stanford University are studying devices that people could strap to their legs to make running easier.

Graphite nanoplatelets on medical devices prevent infections


Graphite nanoplatelets integrated into plastic medical surfaces can prevent infections, killing 99.99 per cent of bacteria which try to attach - a cheap and viable potential solution to a problem which affects millions, costs huge amounts of time and money, and accelerates antibiotic resistance. This is according to research from Chalmers University of Technology, Sweden, in the journal Small.
