Boosting the ability to detect superweak magnetic fields

Each beat of your heart or burst of brain activity relies on tiny electrophysiological currents that generate minuscule ripples in the surrounding magnetic field. These field variations provide the basis for a range of research ...

Lunar sonic booms

The sonic boom created by an airplane comes from the craft's large, speeding body crashing into molecules in the air. But if you shrank the plane to the size of a molecule, would it still generate a shock wave?

High-precision magnetic field sensing

Scientists have developed a highly sensitive sensor to detect tiny changes in strong magnetic fields. The sensor may find widespread use in medicine and other areas.

National MagLab racks up new world record with hybrid magnet

After a decade of planning, designing and building, the Florida State University-based National High Magnetic Field Laboratory now has the strongest magnet in the world for nuclear magnetic resonance (NMR) spectroscopy, a ...

Images from Sun's edge reveal origins of solar wind

Ever since the 1950s discovery of the solar wind - the constant flow of charged particles from the sun - there's been a stark disconnect between this outpouring and the sun itself. As it approaches Earth, the solar wind is ...
