Physics: It’s happening inside your body right now

Simple physics may play a larger role than previously thought in helping control key bodily processes such as how the body fights infection.

Blood Vessel Microchip
Researchers at Georgia Tech and Emory University fabricated model blood vessel systems that include artificial blood vessels with diameters as narrow as the smallest capillaries in the body. The systems were used to study the activity of white blood cells as they were affected by drugs that tend to make them softer, which facilitates their entry into blood circulation.
