magnetic fields

Cardiologists may advise patients with cardiac implantable devices (CIDs) to avoid using AirPods due to the magnetic fields they emit. The article states that these magnetic fields should be kept at a safe distance from CIDs.

Scientists discovered that magnetic fields surrounding newborn stars may facilitate binary star formation by acting as a cosmic brake. These fields strip away angular momentum, allowing two protostars to spiral closer together instead of drifting apart.

A global team led by Australia’s CSIRO created the largest cosmic map of magnetic fields by measuring light from nearly 4 million galaxies as it traveled through intergalactic space. The map aims to help scientists study one of the universe’s most mysterious forces.

A 'Hot Jupiter' exoplanet's winds exceed 15,000 mph, providing the first evidence of magnetic fields in exoplanets. An illustration depicts the magnetic activity observed.

A German research team discovered that pigeons may use magnetic fields for navigation when visibility is limited, with their livers playing a key role in this process. The study highlights an unexpected organ's involvement in avian magnetic navigation.

Scientists have identified iron-rich immune cells in the livers of homing pigeons that may help them detect magnetic fields, as reported in a new study published in Science. The research explores three hypotheses for how birds sense Earth's geomagnetic field, including magnetic particles in the beak, voltage-sensitive ion channels, and retinal pigments, though none fully explain the mechanism.

Scientists used advanced supercomputer plasma simulations to discover how the universe creates large magnetic fields from turbulence. This breakthrough could enhance understanding of stars, black holes, neutron star collisions, and solar eruptions.

Scientists suggest that deep within Uranus and Neptune, extreme pressures and temperatures may create a 'superionic' hybrid phase of carbon and hydrogen, where hydrogen atoms move fluidly through a rigid carbon structure. This discovery could explain the planets' unusual magnetic fields and reshape understanding of heat and electricity flow in their interiors.

Scientists discovered a unique form of superconductivity in uranium ditelluride (UTe2) that temporarily disappears and then reappears under strong magnetic fields. This phenomenon, dubbed the 'Lazarus phase,' challenges existing theories about superconductivity behavior.
