Phys.org / Reversible electric control unlocks persistent chiral phonon states

Atoms in a material are rarely still. They jiggle back and forth in collective lattice vibrations known as phonons. Their motion can also carry a rotational element: In 2023, scientists at PSI experimentally proved the existence ...

Medical Xpress / Atherosclerosis may meet key criteria for autoimmune disease, evidence suggests

In autoimmune diseases, the immune system turns against the body through pathogenic high-affinity B cells or T cells, leading to severe organ damage. Multiple sclerosis (nervous system paralysis), type 1 diabetes (a strong ...
