Highly sensitive sensors to measure the heart and brain activity

Electrical signals measurements such as the ECG (electrocardiogram) can show how the human brain or heart works. Next to electrical signals magnetic signals also reveal something about the activity of these organs. They could ...

Solar weather has real, material effects on Earth

On Sep. 1, 1859, solar astronomer Richard Carrington witnessed sunspots that suddenly and briefly flashed brightly before they disappeared. Just before dawn the next day, auroras erupted over most of the Earth, reaching as ...

Innovative magnets for new energy-recovery accelerator

When it comes to particle accelerators, magnets are one key to success. Powerful magnetic fields keep particle beams "on track" as they're ramped up to higher energy, crashed into collisions for physics experiments, or delivered ...

First observation of a square lattice of merons and antimerons

Scientists have, for the first time, observed a square lattice of merons and antimerons—tiny magnetic vortices and antivortices that form in a thin plate of the helical magnet Co8Zn9Mn3. By finely varying a magnetic field ...

Magnetic materials for motors of the future

According to a statistic from the University of Chicago, 50 percent of U.S. power goes through a motor. Vehicles like cars and planes rely on motors to transform power, as do household appliances like vacuums and refrigerators. ...
