There of course good old wiki.

Membrane science is still an important research area in biology and medicine. This interface between the cell’s interior and its environment is crucial in many aspects of biology. One key discovery is that of aquaporin by Peter Angre in 2003. This discovery won him the Nobel prize in Chemistry together with Roderick Mckinnon, who worked on the structure and mechanism of potassium channels.

Peter Andre’s lecture on aquaporins.

Drinking too much water within a short time can lead to Hyponatremia, which is a condition where the sodium concentration in blood is below 135mmoles per liter. Symptoms of hyponatremia include fatigue, nausea, vomiting, frequent urination and mental disorientation.

For more information on this condition, please read this article by Scientific American.
