A new study has found that the vast majority of coronavirus genomes from Africa are closely related to a single lineage that is different from the ones spreading in Europe and North America. The study, published in the journal Nature, analyzed over 100,000 genomes of the SARS-CoV-2 virus.
Of these genomes, only 3.8 percent belonged to lineages that have been previously identified in Europe and North America. The rest belonged to a single lineage known as 20A.EU1.
This lineage is thought to have first emerged in Africa sometime around mid-October 2020. It then rapidly spread across the continent and has now become the …

It’s been years now since the pandemic started. And in that time, we’ve all changed in some way or another. Some of us have had to become more organized with our time. Others have had to learn how to cook for themselves. And some of us have even had to become better at managing our stress levels.
But one thing that hasn’t changed much is our personalities. Sure, we may be a little more anxious than usual or a little more irritable. But for the most part, our personality types have stayed the same.
Or have they?
It’s possible that our personalities may have changed more than we realize during the …

In early December, as China was grappling with its first known outbreak of a new coronavirus, a Wuhan doctor named Li Wenliang sounded the alarm about the pathogen in a private chat group. He was reprimanded by the police and silenced. But his early warnings would ultimately help spur the world’s response to Covid-19. The Chinese ophthalmologist later died from the virus himself; his death led to public outcry and nationwide mourning in China.
The discovery of the novel coronavirus responsible for COVID-19 was a significant scientific achievement. The identification and sequencing of the virus have allowed researchers to better …
