Two takes on lithium-ion batteries

Lithium-ion batteries have transformed our lives. Without them, we wouldn't have laptop computers or cell phones—at least, not the long-lived, lightweight kindwe're used to—and in the near future they may become more ...

How confined protons migrate

Protons (H+) and hydronium ions (H3O+) in free aqueous solutions seem to migrate faster than other ions due to the the Grotthuss-mechanism. Individual protons do not really migrate at all. Instead, bonds of the hydronium ...

Channeling our ion past

To understand how the first cells transported ions across their membranes, researchers are studying simple channels used by fungi to kill off bacteria.

How does potassium enter cells?

For decades, it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers at Goethe University Frankfurt and University Groningen have ...

US followed Boeing's lead on 787 battery testing (Update 3)

U.S. regulators let Boeing help write the safety conditions for the problematic battery system in its beleaguered 787 "Dreamliner," prescribe how to test it and carry out those tests itself, according to testimony and documents ...
