In 1916, Albert Einstein predicted the existence of gravitational waves. It took almost 100 years and the construction of the Laser Interferometer Gravitational-Wave Observatory (LIGO) to show that he was right. In 2015, a brilliant team of researchers detected gravitational ripples that had been generated by the collision of two black holes about 1.3 billion years ago.
How’s this for a paradox: The better cancer centers become at keeping patients alive, the more expensive cancer care becomes. This brutal tradeoff hits harder in rural areas, where the cancer burden is higher and the investigator and clinical trial representation is lower.
