The vestibular system, a set of structures in the inner ears that helps with balance, may grant the birds their special ability ...

Research groups have made a breakthrough in the field of hard disk drives (HDD) by demonstrating the feasibility of multi-level recording using a three-dimensional magnetic recording medium to store ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Pigeons can sense Earth’s magnetic field by detecting tiny electric currents in their inner ears, a team of researchers suggests. Such an inner compass could help to explain how certain animals can ...

Scientists have demonstrated a new recording principle that improves recording efficiency by 35% by combining spin torque with conventional heat-assisted magnetic recording (HAMR). This advancement is ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating ...

Schematic view of (top) currently used HAMR and (bottom) three-dimensional magnetic recording systems. In the three-dimensional magnetic recording system, the Curie temperature of each recording layer ...

Laser heating generates a temperature gradient in the MnPt layer, which induces spin currents (green arrows) that are injected into the FePt layer. These spin currents generate spin torque, which ...
