A Brazilian city devastated by COVID-19 may have reached herd immunity
Up to half of Manaus was infected at the epidemic’s peak, which slowed further spread of the virus but also led to many deaths, scientists say.

Early immune responses may be why younger people get less sick from COVID-19
Age-related differences in coronavirus immune defenses hint that a boost in early immune responses from drugs or a vaccine could help protect people.

What will happen when COVID-19 and the flu collide this fall?
As the Northern Hemisphere braces for a coronavirus-flu double hit, it’s unclear if it’ll be a deadly combo or one virus will squeeze out the other.
- Microbes
50 years ago, scientists were on the trail of a brain-eating amoeba
In 1970, scientists were studying a brain-eating amoeba that had been implicated in a newfound disease. Today, infections by the parasite are still poorly understood.

Seven footprints may be the oldest evidence of humans on the Arabian Peninsula
In what’s now desert, people and other animals stopped to drink at a lake more than 100,000 years ago, a new study suggests.

Blood donations show that the United States is still nowhere near herd immunity
Testing donated blood for antibodies to the coronavirus highlights that the vast majority of the United States remains susceptible to infection.

‘The Origins of You’ explores how kids develop into their adult selves
A new book describes the interplay of nature and nurture as children, at least in Western societies, grow up.

Lung cell images show how intense a coronavirus infection can be
Microscopic views reveal virus particles coating the hairlike cilia of an airway cell from the lungs.

Treatments that target the coronavirus in the nose might help prevent COVID-19
Scientists are developing and testing ways to prevent the virus from settling in prime nasal real estate.
