Hot stars are plagued by giant magnetic spots

Astronomers using European Southern Observatory (ESO) telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters. Not only are these stars plagued by magnetic spots, some also ...

New sunspots potentially herald increased solar activity

On May 29, 2020, a family of sunspots—dark spots that freckle the face of the sun, representing areas of complex magnetic fields—sported the biggest solar flare since October 2017. Although the sunspots are not yet visible ...

New understanding of RNA movements can be used to treat cancer

Research from Karolinska Institutet published today in Nature shows that an RNA molecule involved in preventing tumour formation can change its structure and thereby control protein production in the cell. The finding can ...

Van der Waals junction spin valves without spacer layer

The fundamental principle of a spin valve is that the resistance is dependent on the parallel or antiparallel configurations of the two ferromagnetic electrodes, thus associating the magnetoresistance (MR) effect, whose basic ...
