Magnetic effect without a magnet

Electric current is deflected by a magnetic field—in conducting materials, this leads to the so-called Hall effect. This effect is often used to measure magnetic fields. A surprising discovery has now been made at TU Wien, ...

China's temperate glaciers are melting at accelerating rate

Temperate glaciers are very sensitive to variations in temperature and precipitation, and thus represent a good indicator of climate change. China's temperate glaciers have a relatively warm and humid climate and hydrothermal ...

Research reveals stellar kinematics of the galactic disc

By using a sample of 118945 red giant branch (RGB) stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and Gaia, Dr. Wu Yaqian from the National Astronomical Observatories of the Chinese Academy ...

Image: Hubble views a baby star's tantrums

Herbig-Haro objects are some of the rarer sights in the night sky, taking the form of thin spindly jets of matter floating among the surrounding gas and stars. The two Herbig-Haro objects cataloged as HH46 and HH47, seen ...

Effects of past ice ages more widespread than previously thought

Cold temperatures, prevalent during glacial periods, had a significant impact on past and modern unglaciated landscapes across much of North America, according to a recent study by University of Arkansas geologist Jill A. ...
