01/05/2020Steady hands and uninterrupted, sharp vision are critical when performing surgery on delicate structures like the brain or hair-thin blood vessels. While surgical cameras have improved what surgeons see during operative procedures, the "steady hand" remains to be enhanced.
30/04/2020The COVID-19 pandemic is confronting manufacturing companies with major upheavals. Fraunhofer IPK’s initiative "Manufacturing despite Corona" supports the manufacturing industry in quickly and efficiently adapting to the changed framework conditions.
29/04/2020Miniature biological robots are making greater strides than ever, thanks to the spinal cord directing their steps. University of Illinois at Urbana-Champaign researchers developed the tiny walking "spinobots," powered by rat muscle and spinal cord tissue on a soft, 3D-printed hydrogel skeleton.
28/04/2020Today's virtual reality systems can create immersive visual experiences, but seldom do they enable users to feel anything -- particularly walls, appliances and furniture. A new device developed at Carnegie Mellon University, however, uses multiple strings attached to the hand and fingers to simulate the feel of obstacles and heavy objects.
24/04/2020The destructive force of a tornado occurs due to the extremely high rotational speeds in its center, which is called “vortex”. Surprisingly, similar effects as in such storms are predicted for light that travels along an atomically smooth gold surface. This light can exhibit angular momentum and vortices.
23/04/2020The use of mechanical ventilation can save lives. But at the same time, the ventilation pressure puts immense stress on delicate lung tissue. Especially for patients with preexisting lung damage, the use of ventilators can prove deadly. A computational lung model that’s been developed by the Technical University of Munich can be used to reduce damage caused by mechanical ventilation.
22/04/2020Jing Wang and his team at Empa and ETH Zurich usually work on measuring, analyzing and reducing airborne pollutants such as aerosols and artificially produced nanoparticles. However, the challenge the whole world is currently facing is also changing the goals and strategies in the research laboratories. The new focus: a sensor that can quickly and reliably detect SARS-CoV-2 - the new coronavirus.
21/04/2020Powder Aerosol Deposition enables ceramic coatings production at normal room temperatures.
17/04/2020Coronary artery disease is the most common type of heart disease, according to the Centers for Disease Control and Prevention. About 18.2 million adults in the United States have coronary artery disease.
16/04/2020Scientists have been using fluorescence microscopy to study the inner workings of biological cells and organisms for decades. However, many of these platforms are often too slow to follow the biological action in 3D; and too damaging to the living biological specimens with strong light illumination.
