Phys.org / Silver-infused zeolite efficiently separates xenon from krypton for industrial use

An international team of researchers have found a better way to separate two rare and important gases—xenon and krypton—that are often combined in chemical, petrochemical, metallurgical, and environmental processes.

Phys.org / New building blocks of cell communication: How an invisible 'cap' could control electrical synapses

When two cells "talk" to each other, they often do so through tiny channels called electrical synapses. Unlike chemical synapses, these so-called gap junctions enable the direct exchange of information between two cells, ...
