The detection by the upgraded Laser Interferometer Gravitational - Wave Observatory (Advanced LIGO), along with two subsequent gravitational wave discoveries, confirmed a
major prediction of Einstein's 1915 general theory of relativity and
heralded a new era in physics, allowing scientists to
study the universe in a new way by using gravity instead of light.
The advent of human induced pluripotent stem cells has been
heralded as a
major breakthrough in the
study of pluripotent stem cells, for these cells have yielded fundamental insights into the reprogrammability of somatic cell fates, but also because of their seemingly great promise in applications, including potential uses in cell therapy.
