Researchers at OIST built a graphite disk that levitates and spins for hours in a vacuum, showing how perfect magnetic symmetry can cancel energy loss.
Ofer Cohen works for the University of Massachusetts Lowell. The university benefits from any public article that is written by one of its faculty in terms of exposure and visibility. Ofer Cohen ...
In a remarkable leap for quantum physics, researchers in Japan have uncovered how weak magnetic fields can reverse tiny ...
Recent scientific revelations have brought to light that Earth’s magnetic field, our primary line of defense against harmful solar radiation, can experience significant weakening in a matter of months ...
A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...
