Observed live with X-ray laser: Electricity controls magnetism
Researchers from ETH Zurich and the Paul Scherrer Institute PSI demonstrate how the magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future.
Physicists reveal novel magnetoelectric effect
(Phys.org) —New research at the University of Arkansas reveals a novel magnetoelectric effect that makes it possible to control magnetism with an electric field.
Young star suggests our sun was a feisty toddler
If you had a time machine that could take you anywhere in the past, what time would you choose? Most people would probably pick the era of the dinosaurs in hopes of spotting a T. rex. But many astronomers would ...
Magnetic fields are crucial to exomoon habitability
Astronomers believe that hidden deep within the wealth of data collected by NASA's Kepler mission are minuscule signatures confirming the presence of exomoons. With such a promising discovery on the horizon, ...
Solar flares may disrupt GPS systems, researcher says
(Phys.org) —If your GPS navigation system goes on the fritz in the coming days, you might have the sun to blame. Early this week, the sun released four X-class solar flares, the strongest type of flare. Forecasters at the ...
Cluster spacecraft detects elusive space wind (w/ Video)
A new study provides the first conclusive proof of the existence of a space wind first proposed theoretically over 20 years ago. By analysing data from the European Space Agency's Cluster spacecraft, researcher ...
Super spider silk opens way to nano medical devices
Scientists in the United States said on Tuesday they had coated spider silk with carbon nanotubes, creating a fibre that is not only super-strong but also conducts electricity.
How a metamaterial might improve a depression treatment
A brain stimulation technique that is used to treat tough cases of depression could be considerably improved with a new headpiece designed by University of Michigan engineers.
MAVEN Solar Wind Electron Analyzer seeks answers at microscopic levels
When the Mars Atmosphere and Volatile Evolution Mission launches in November to study why the Red Planet is losing its atmosphere, one of its instruments will look to electrically charged particles called ...
Building a better tokamak by blowing giant plasma bubbles
Advanced computer codes are helping scientists reimagine how they might initiate a fusion reaction in the center of a tokamak, a doughnut-shaped experimental vessel. These simulations are also shedding new ...
ESA launches Swarm research satellites in Russia (Update)
The European Space Agency (ESA) on Friday launched a trio of hi-tech satellites on an unprecedented mission to map anomalies in Earth's magnetic field.
Smart materials investigated on space station
If you have a smartphone, take it out and run your fingers along the glass surface. It's cool to the touch, incredibly thin and strong, and almost impervious to scratching. You're now in contact with a "smart material."
Female astronauts have a lower threshold for space radiation than their male counterparts
Why are there more men than women in space? The answer might not be as straightforward as you first think. According to physiological models used by NASA, female astronauts have a lower threshold for space ...
Where are the best windows into Europa's interior?
(Phys.org) —The surface of Jupiter's moon Europa exposes material churned up from inside the moon and also material resulting from matter and energy coming from above. If you want to learn about the deep ...
