Our surprising magnetic galaxy

From University of Tokyo 12/01/24 A team of astronomers including those from the University of Tokyo created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the […]

Unconventional magnets: stress reduces frustration

From TU Wien 07/01/24 Magnetism occurs depending on how electrons behave. For example, the elementary particles can generate an electric current with their charge and thereby induce a magnetic field. However, magnetism can also arise through the collective alignment of the magnetic moments (spins) in a material. What has not been possible until now, however, […]

When is an aurora not an aurora?

From University of California – Berkeley 13/12/23 The shimmering green, red and purple curtains of the northern and southern lights — the auroras — may be the best-known phenomena lighting up the nighttime sky, but the most mysterious are the mauve and white streaks called Steve and their frequent companion, a glowing green “picket fence.” […]

Rice-engineered material can reconnect severed nerves

From Rice University 29/10/23 Researchers have long recognized the therapeutic potential of using magnetoelectrics ⎯ materials that can turn magnetic fields into electric fields ⎯ to stimulate neural tissue in a minimally invasive way and help treat neurological disorders or nerve damage. The problem, however, is that neurons have a hard time responding to the […]
