![]() ![]() While the disease continues to spread and cause death, help is in sight thanks to the record-setting effort to develop vaccines. In the United States, more than 19 million patients have tested positive for the disease and more than 338,000 of them have died. Since the first case of Covid-19 was reported in China late last year, more than 802 million cases and more than 1.7 million deaths have been confirmed around the world. Presenting the key innovations, studies and discoveries that made 2020 an unforgettable year in science: It’s a subjective round-up, of course, but one compiled by our editors after much thought and debate. But none of those moments made this list of the biggest science stories of the year. In incredible advances, researchers used three new tools for making discoveries about the sun, discovered that dinosaurs got cancer and published a study on a discovery in a Mexican cave that changes the timeline of humans’ arrival to the Americas. The world grappled with how to combat the SARS-CoV-2 virus, learning about how it spread (whether it was on surfaces, via droplets or being airborne) and how it affected the human body (from immunity to symptoms like loss of smell.) But scientific endeavors in other fields, whether affected directly by the pandemic or indirectly by public health measures, didn’t come to a complete halt because of SARS-CoV-2. ![]() Covid-19 dominated science coverage in 2020, and rightly so.
