An international team of researchers found periodic brightening in the red dwarf star GJ 436, attributing it to interactions between its magnetic field and that of its close-orbiting exoplanet, which has a magnetic field over 10 times stronger than Earth's.
A 2022 study found that the magnetic fields of devices like Apple's AirPods can trigger magnetic modes in implanted cardiovascular devices, potentially preventing them from detecting irregularities. While patients should consult their cardiologists, Apple recommends keeping devices at least 6 inches away from implants.
A global team led by CSIRO has created the largest-ever map of cosmic magnetic fields by measuring light from nearly 4 million galaxies. The "SPICE_RACS" map, made possible by the ASKAP radio telescope in Western Australia, will help scientists investigate fundamental questions about the universe's magnetic origins and evolution.
