Each year, many shark species migrate hundreds of miles, traversing ocean waters to return to the same spot year after year. Now, Florida State University researchers have found that sharks likely use the Earth’s magnetic fields to help guide them on these long-distance journeys.
The Event Horizon Telescope (EHT) has produced a new image showing details of the magnetic fields in the region closest to the supermassive black hole at the core of the galaxy M87, providing clues about how its powerful jets are produced.
Researchers routinely measure magnetic fields to better understand a vast array of natural phenomena. Many of these measurements are performed in shielded environments, but the research community has achieved these sensitive measurements in extreme environments as well as outside of highly controlled environments. In AVS Quantum Science, researchers discuss ways in which various predominantly optically pumped magnetometer technologies have been adapted for use in a wide range of noisy and physically demanding environments.
Notre Dame researchers will use data from the new high-speed light detectors to determine the temperature of the sun’s lower atmosphere, measure the spectrum of solar flares and gain a better understanding of the role magnetic fields play in solar flare generation.
Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.
A new image from the VLA dramatically reveals the extended magnetic field of a spiral galaxy seen edge-on from Earth.
Researchers from UC San Diego and Brookhaven Laboratory in New York investigated a diverse population of meteorites. Among the 15 pieces of comets and asteroids studied, they found two with superconductive grains.
VLA observations reveal large-scale magnetic field that spirals outward into a galaxy’s extended halo.
