Giant viruses build a cell nucleus surprisingly like our own

Humans aren't the only targets for viruses. Like us, bacteria become infected by many types of viruses. In fact, across billions of years, bacteria and viruses have engaged in a non-stop evolutionary arms race for survival that includes countless innovations and counter-adaptatio … | Continue reading

Researchers work to restore iconic West Virginia red spruce forests 

Clearcutting and wildfires decimated the red spruce, once the dominant, high-elevation tree species in West Virginia, in the late 1800s and early 1900s. Nowadays, only 10% of the state's historic red spruce coverage remains and it faces a new threat in climate change.   | Continue reading
