For the first time ever, scientists at the TRIGA research reactor of the Johannes Gutenberg University Mainz have determined the velocity distribution of ultracold neutrons (UCN) emitted by a deuterium ice crystal. 'We have taken a big step forward in our efforts to accumulate and store great amounts of these ultracold neutrons to then be able to analyse them in more detail,' explained Professor Christian Plonka-Spehr of the Institute of Nuclear Chemistry…

Policymakers and economists often promote managed-care plans based on the assumption that they prevent the overuse of unnecessary surgical procedures or help steer patients to high-quality providers, compared to traditional fee-for-service insurance plans.

Obesity affects health in several ways, but new research shows obesity can have minimal impact on ovarian cancer survival. A study by researchers at the University of Alabama at Birmingham (UAB) Comprehensive Cancer Centre found ovarian cancer survival rates are the same for obese and non-obese women if their chemotherapy doses are closely matched to individual weight…
