Winners of the 2021 Nobel Prizes in chemistry, physics and medicine received their awards in a scaled-down ceremony in Washington, adapted for pandemic times. U.S.-based physics laureate Syukuro Manabe, chemistry laureate David W.C. MacMillan and economic sciences laureate Joshua D. Angrist were presented their medals and diplomas by Karin Olofsdotter, the Swedish ambassador to the United States. The coronavirus scuttled the traditional formal banquet in Stockholm for a second year. It is usually attended by all winners. Other ceremonies will take place this week in Europe and the United States. The Nobel Peace Prize will be awarded separately in Norwegian capital Oslo on Friday.
