Scientists have discovered a universal pattern of brain waves in multiple primate species, including humans. This pattern of electrical activity is seen in the six layers of tissue that cover the ...

Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the ...

(a) Ordinary electrons without wave shaping have a uniform wave pattern when they travel. In simulations, the electrons collide with the atoms in graphene (red spheres represent graphene atoms and ...
