2020 has been a lousy year for humans, but an awesome one for science.

Beginning in February, scientists and physicians around the world made a series of scientific breakthroughs. They decoded the genetics of the deadly SARS-CoV-2 virus, and figured out how it invaded cells, made people sick with COVID-19 and sometimes killed them. They developed diagnostic tests, and researchers at pharmaceutical companies created, tested and manufactured several spectacularly effective vaccines. And they did it all in nine months – a record, writes David Pride, a physician and scientist at the University of California, San Diego.

With vaccines now being injected into the arms of people in the U.S. and around the world, the end of this terrible, horrible, no good, very bad pandemic is in sight.

So I say: GO SCIENCE! And keep wearing your mask.

The top scientific breakthrough for 2020 was understanding SARS-CoV-2 and how it causes COVID-19 – and then developing multiple vaccines

The development of multiple vaccines against the virus that causes COVID-19 has been hailed as the breakthrough of 2020. But there were many more supporting discoveries that made this possible.
