As part of our year in review, we're looking at the biggest health and science stories of 2017 with WBUR's Carey Goldberg.

2017 has, largely, been a positive year in the health and sciences. There have been no major disease outbreaks, no new Zika, no new Ebola. But there have been a number of discoveries that make the future of health and science seem hopeful: a new cancer therapy, Car-T, and the team who discovery gravitational waves in 2016 was awarded a Nobel Prize in Physics. And good news for Massachusetts: the state has been ranked the healthiest in the country in a report called American Health Rankings.
