(Phys.org)—When a kitchen sponge adsorbs water into its pores, it softens and expands. Now in a new study published in The Journal of Physical Chemistry Letters, scientists have discovered that, when microporous materials ...
The surface of a single cell contains hundreds of tiny pores, or ion channels, each of which is a portal for specific ions. Ion channels are typically about 1 nanometer wide; by maintaining the right balance of ions, they ...

A cell does everything it can to protect its nucleus, where precious genetic information is stored. That includes controlling the movement of molecules in and out using gateways called nuclear pore complexes (NPCs).

When cells age or suffer damage, they are able to actively bring about their own pre-programmed death – a "suicide" process known as apoptosis. A desensitization of this process determines the change from a normal cell ...
