How the universe got its magnetic field

When we look out into space, all of the astrophysical objects that we see are embedded in magnetic fields. This is true not only in the neighborhood of stars and planets, but also in the deep space between galaxies and galactic ...

Research reveals a new mechanism to transfer chirality between molecules in the nanoscale field

If we compare the right to the left hand, we can see these are specular images—that is, like symmetrical shapes reflected in a mirror—and they cannot superimpose on each other. This property is chirality, a feature of ...
