This is what a solid made of electrons looks like
If the conditions are just right, some of the electrons inside a material will arrange themselves into a tidy honeycomb pattern - like a solid within a solid. Physicists have now directly imaged these 'Wigner crystals', named after the Hungarian-born theorist Eugene Wigner, who first imagined them almost 90 years ago.
Electron whirlpools: Scientists witness electricity behaving like water
Researchers at MIT have observed "electron whirlpools" for the first time. The bizarre behavior arises when electricity flows as a fluid, which could make for more efficient electronics. Like water, electricity is made up of discreet particles, so one might expect that they would both flow in similar ways.
