Heterostructures with magnetism and topology (geometry) are promising materials to realize exotic topological quantum states. However, such materials are challenging to engineer or synthesize. In a new report on Science Advances, ...
The Marangoni effect is a popular physics experiment. It is produced when an interface between water and air is heated in just one spot. Since this heat will radiate outwards, a temperature gradient is produced on the surface, ...

Astronomers have conducted spectroscopic observations of three magnetic chemically peculiar (CP) stars, HD 188041, HD 111133 and HD 204411. Results of these observations, presented in a paper published July 8 on arXiv.org, ...
Europe's massive heat wave is on its way out—and it's leaving a slew of broken temperature records in its wake. Many countries were gripped by temperatures above 104 Fahrenheit (40 degrees Celsius) between June 26 and June ...

A team of researchers working at the University of Twente has solved the mystery of why a drop of oil bounces repeatedly when dropped in a water/ethanol gradient but eventually falls to the bottom of a jar. In their paper ...
The effects of extreme warming have been felt across the globe in recent years, especially with intensely hot summers in eastern Asia, western Europe, and North America. On July 21, 2017, a weather station in Shanghai, China, ...
