The birth of a very-high-field superconductor

The strong magnetic fields of an MRI scanner or a particle accelerator are generated efficiently by electromagnets that have superconducting wire in their coils. A group of scientists has discovered how to make better wires ...

Knobbly knees in competition with fingerprints

Forget digital fingerprints, iris recognition and voice identification, the next big thing in biometrics could be your knobbly knees. Just as a fingerprints and other body parts are unique to us as individuals and so can ...

Magnetic fields created before the first stars

Magnets have practically become everyday objects. Earlier on, however, the universe consisted only of nonmagnetic elements and particles. Just how the magnetic forces came into existence has been researched by Prof. Dr. Reinhard ...

Concerns raised about airline boarding pass barcodes

(Phys.org)—Boarding passes for travel on airlines in the US (and many other countries) now include barcodes, but an aviation security researcher has now learned that these barcodes can be read by readily available tools ...

NASA's TRMM satellite sees birth of Arabian Sea cyclone
