Scientists from around the world have turned their attention to the coronavirus, including molecular geneticists who are trying to draw a picture of its family tree to better understand how it has spread – and may in the future. What about its transmission in the air? An aerosol expert digs into what the emerging research says.
Also this week, an archaeologist shares his research to more accurately date indigenous people’s history in North America and a scientific attempt to find out if shouting at urban coyotes actually deters them.

Every time the virus copies itself it makes mistakes, creating a trail that researchers can use to build a family tree with information about where it's traveled, and when.

Aerosols are the tiny particles of liquid and material that float around in our environment. When they come from an infected person, they may be a significant source of coronavirus transmission.

Biologists capture and collar coyotes in urban Los Angeles in order to study the effectiveness of 'hazing' as a wildlife management tool.
