If you want an electrical current to flow around a normal metal ring you have to supply enough energy to overcome the metal’s resistance – right? Not always, according to physicists in the US and ...

If you think about an asylum, there are two kinds of people in it: staff and patients. We aren’t sure which one [Nick Lucid] is in the latest The Science Asylum video that tries to answer the question ...

Physicists have now observed electron whirlpools. Theorists have long predicted electrons should exhibit this hallmark of fluid flow; the findings could inform the design of more efficient electronics ...

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, ...

A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic ...

If you ever wished electrons would just behave, this one’s for you. A team from Tohoku, Osaka, and Manchester Universities has cracked open an interesting phenomenon in the chiral helimagnet α-EuP 3: ...

The Chlamydomonas reinhardtii proton gradient regulation5 (Crpgr5) mutant shows phenotypic and functional traits similar to mutants in the Arabidopsis (Arabidopsis thaliana) ortholog, Atpgr5, ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...
