Positive and Negative Feedback Loops
Paul Andersen explains how feedback loops allow living organisms to maintain homeostasis. He uses thermoregulation in mammals to explain how a negative feedback loop functions. He uses fruit ripening to explain how a positive feedback...

Type 2 Diabetes and Daily Blood Sugar Monitoring
Research is telling us that those with Type 2 diabetes don't need to be testing for blood glucose levels at home and that doing so is a waste of money and a strain on the health care system.
