NY leads in science. We must invest in biomedical research | Opinion We are at an inflection point in how we support science in the U.S. New York state must invest in its science institutions and workforce.

New opinion in @lohud.com by Jonathan Teyan & Paola Bianchimano on why NYS must invest in biomedical research through EBRI including the fact that NY trains 1 in 7 U.S. doctorsโ€”and public research investment delivers up to a 10:1 economic return. EBRI would secure both. www.lohud.com/story/opinio...
