Associate Professor Jonathan Boreyko and graduate fellow Mojtaba Edalatpour have made a discovery about the properties of water that could provide an exciting addendum to…
Images from NASA satellite of polar cyclones on Jupiter allow scientists to study the forces that drive them. Hurtling around Jupiter and its 79 moons…
Theory and simulations reveal why seemingly weak effects sometimes play a strong role in how particles move through the air close to the Earth’s surface….
Scientists at TU Wien answer an age-old question: How can the so-called “teapot effect” be explained? The “teapot effect” has been threatening spotless white tablecloths…
Ventilation systems designed to avoid spreading COVID-19 should be based on the air circulation within a room. As we approach two full years of the…
New mechanism found for generating giant vortices in quantum fluids of light. Anyone who has drained a bathtub or stirred cream into coffee has seen…
Applying a “one-size-fits-all” policy recommendation to a complicated public sphere. Along with the use of face masks, social distancing in public remains one of the…
