Spintronics seeks to exploit the interplay of spin-polarized conduction electrons and magnetization in nanostructures. Spin-dependent scattering leads to giant magnetoresistance 1,2,3,4,5 (GMR ...

A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black holes or a cosmic particle accelerator.

Giant atoms with Rydberg states have already been successfully used for such techniques in other contexts." More information: Xiaoling Wu et al, Dissipative time crystal in a strongly interacting ...

A crystal is an arrangement of atoms that repeats itself in space, in regular intervals: At every point, the crystal looks exactly the same. In 2012, Nobel Prize winner Frank Wilczek raised the ...

Huge galaxy cluster is wrapped in a cocoon 20 million light-years wide, NASA space telescope finds Astronomers discover 15 new giant radio galaxies — the largest single objects in the universe ...

Scientists have discovered unexpectedly high number of giant exoplanets in a cluster of stars called Messier 67 that is about the same age as the Sun — indicating that our solar system might ...

A giant sunspot cluster rivaling the one that caused the Carrington Event in 1859 could trigger a cannibal coronal mass ejection. But this is unlikely to cause major problems.
