We summarize the week's scientific breakthroughs every Thursday.
- Neuroscience
Tiny, magnetically controlled robots coax nerve cells to grow connections
Research using microrobots and nerve cells from rats could point to new treatments for people with nerve injuries.

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.
- Health & Medicine
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.
- Health & Medicine
Antibodies made in the lab show some promise for treating COVID-19
Preliminary results from two companies hint that the proteins can help COVID-19 patients from needing hospitalization or ventilation.
- Health & Medicine
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.
- Anthropology
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.
- Health & Medicine
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.
- Science & Society
‘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.
- Health & Medicine
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.
- Health & Medicine
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.
- Health & Medicine
College athletes show signs of possible heart injury after COVID-19
Four of 26 college athletes, who had mild or asymptomatic COVID-19, may have had myocarditis, an inflammation of the heart muscle.
