DURHAM, N.C. When you think about what separates humans from chimpanzees and other apes, you might think of our big brains, or the fact that we get around on two legs rather than four. But we have another distinguishing feature: water efficiency.
That s the take-home of a new study that, for the first time, measures precisely how much water humans lose and replace each day compared with our closest living animal relatives.
Our bodies are constantly losing water: when we sweat, go to the bathroom, even when we breathe. That water needs to be replenished to keep blood volume and other body fluids within normal ranges.

Researchers show how disgust evolved as an emotion
Next time a refrigerator door opens to the smell of rotting uncooked chicken, consider the moment as an odorous encounter with the origin of disgust. That repulsion is linked to an evolved human emotion that helps avoid exposure to something sickening.
In a project that blended anthropology, biology and psychology, a University of Oregon team explored disgust by studying how Ecuador’s indigenous Shuar people, living in communities with differing levels of market integration, respond to revolting things.
The research was detailed in a paper published online Feb. 23 ahead of print in the Proceedings of the National Academy of Sciences.
