PHILADELPHIA - The lining of the intestine regenerates itself every few days as compared to say red blood cells that turn over every four months. The cells that help to absorb food and liquid that humans consume are constantly being produced. The various cell types that do this come from stem cells that reside deep in the inner recesses of the accordion-like folds of the intestines, called villi and crypts.
PHILADELPHIA — Vision is amazing because it seems so mundane. Peoples’ eyes, nerves and brains translate light into electrochemical signals and then into an experience of the world around them. A close look at the physics of just the first part of this process shows that even seemingly simple tasks, like keeping a stable perception of an object’s color in different lighting conditions or distinguishing black and white objects, is, in fact, very challenging.

PHILADELPHIA - Obesity and insulin resistance are almost inevitably associated with increases in lipid accumulation in the liver, a serious disease that can deteriorate to hepatitis and liver failure. A real paradox in understanding insulin resistance is figuring out why insulin-resistant livers make more fat. Insulin resistance occurs when the body does a poor job of lowering blood sugars.
