This scope has nearly the identical specifications to the one I bought for medical school 20 years ago. The optics are just wonderful. What amuses me is the fact that this scope costs 1/4 of what we all paid back then! For the high school, college or med...

A new study shows, for the first time in humans, that ventilators combined with diaphragm disuse contributes to muscle atrophy in the diaphragm in as little as eighteen hours.

Muscle atrophy in the diaphragm is a major contributor of why patients who have undergone prolonged mechanical ventilation often have difficulty breathing after being removed from the ventilator.

Without a ripple in the water, alligators dive, surface or roll sideways, even though they lack flippers or fins.

University of Utah biologists discovered gators maneuver silently by using their diaphragm, pelvic, abdominal and rib muscles to shift their lungs like internal floatation devices: toward the tail when they dive, toward the head when they surface and sideways when they roll.
