But a new National Institutes of Health study states that calcium supplementation is not a risk. So who are we to believe? It’s an important issue, because more than 40% of […]

Study reveals new pathway in night vision acuity

A new study has revealed a critical process that allows for correction of visual errors in low light conditions. Perception of light is facilitated by rhodopsin receptors in the eye, which detect small particles of light known as photons. Detection of these photons induces a chemical cascade that eventually translates these signals to the nervous […]
