So, if the cell membrane were a lipid, how would it be organized? In 1890, Rayleigh, working on simple oils, showed that they tend to spread over the surface of water. By measuring the original ...

In the generic PEM fuel cell pictured at left, the membrane lies sandwiched between a positively charged electrode (the cathode) and a negatively charged electrode (the anode). In the simple ...

Researchers have identified ancient proteins that may help explain how the first complex cells evolved from simpler ones over 15 billion years ago I ...
