A team of researchers working at the University of St Andrews in Scotland has found a way to place a laser inside a living human cell. In their paper published in the journal Nano Letters, the team describes their technique ...
(Phys.org)—Sodium ions are key regulators in cellular processes. The fluids in cells, whether it is water, blood plasma, or nutrients, are regulated by the sodium concentration in cells. If scientists could study sodium ...
Over the last decade, powerful new microscopes have dramatically sharpened biologists' focus on the molecules that animate and propel life. Now, a new imaging platform developed by Eric Betzig and colleagues at the Howard ...
