According to research published in the journal Physical Review Letters, permanent magnets akin to those used on refrigerators could speed the development of fusion energy. Phys.Org reports: In principle, such magnets can greatly simplify the design and production of twisty fusion facilities called stellarators, according to scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the…

Neutron star with measured at 11 kilometers radius
An international research team led by members of the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) has obtained new measurements of how big neutron stars are. To do so, they combined a general first-principles description of the unknown behavior of neutron star matter with multi-messenger observations of the binary neutron star merger GW170817. Their results, which appeared in…
Team obtains the best measurement of neutron star size to date
An international research team led by members of the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) has obtained new measurements of how big neutron stars are. To do so, they combined a general first-principles description of the unknown behavior of neutron star matter with multi-messenger observations of the binary neutron star merger GW170817.

Ancient humans in India survived Toba super-volcano eruption
The Toba super-volcano eruption 74,000 years ago was 5,000 times larger than that of Mount St. Helens. Somehow, ancient human populations in India survived it. Source: https://earthsky.org/human-world/humans-india-survived-toba-super-volcano…
Globular cluster billowing in the galactic wind
The galactic magnetic field plays an important role in the evolution of the galaxy, but its small-scale behaviour is still poorly known. It is also unknown whether it permeates the halo of the galaxy or not. By using observations of pulsars in the halo globular cluster 47 Tuc, an international research team led by Federico Abbate from the Max Planck Institute…
Twisted 2-D material gives new insights into strongly correlated 1-D physics
Researchers from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg, the RWTH Aachen University (both in Germany) and the Flatiron institute in the U.S. have revealed that the possibilities created by stacking two sheets of atomically thin material atop each other at a twist are even greater than expected. …
Quantum logic spectroscopy unlocks potential of highly charged ions
Scientists from the PTB and the Max Planck Institute for Nuclear Physics (MPIK), both Germany, have carried out pioneering optical measurements of highly charged ions with unprecedented precision. To do this, they isolated a single Ar13 + ion from an extremely hot plasma and brought it practically to rest inside an ion trap together with a laser-cooled, singly charged ion. Employing…
An ultrafast microscope for the quantum world
The operation of components for future computers can now be filmed in HD quality, so to speak. Manish Garg and Klaus Kern, researchers at the Max Planck Institute for Solid State Research in Stuttgart, have developed a microscope for the extremely fast processes that take place on the quantum scale. This microscope—a sort of HD camera for the quantum world—allows the…
Heat wave signals the growth of a stellar embryo
An international research team with the Max Planck Institute for Astronomy (MPIA) participating has detected a propagating heat wave near a massive protostar. It confirms the scenario that such objects grow in bursts. This wave became visible by observing naturally generated microwave lasers, whose spatial arrangement changed unexpectedly rapid.

Hot gas feeds spiral arms of the Milky Way
An international research team, with significant participation of astronomers from the Max Planck Institute for Astronomy (MPIA), has gained important insights into the origin of the material in the spiral arms of the Milky Way, from which new stars are ultimately formed. By analysing properties of the galactic magnetic field, they were able to show that the dilute so-called warm ionized…
