Why are scientists trying to grow organs at the International Space Station? People live on Earth not in zero-gravity. A stem cell expert explains why it is useful to do these experiments in space.
S. pneumoniae, the bacteria responsible for pneumonia, causes about one million deaths each year. Now we know how it uses the sugar raffinose to spread through the body to cause disease.
Parasites do very well for themselves, which is why they are so common in the animal kingdom.

The COVID-19 pandemic is interrupting scientific field work across North America, leaving blank spots in important data sets and making it harder to track ecological change.
Researchers from Oregon Health and Science University found that variations in genes that code for parts of the cellular alarm system might play a role in how well people fight off COVID-19.

Researchers are turning microbes into microscopic construction crews by altering their DNA to make them produce building materials. The work could lead to more sustainable buildings.
The U.S. has been scrambling to get testing for the coronavirus up to speed.

A molecular biologist explains who should get tested, how the tests work and what the US government is doing to make tests available during a rapidly changing crisis.
These grasshoppers, like many insects around the world, are declining.

In the real world, new diseases emerge from complex environments. To learn more about how, scientists set up whole artificial ecosystems in the lab, instead of focusing on just one factor at a time.
Talk of bioterrorism might provoke fears of smallpox and anthrax, but mundane threats like salmonella may pose greater danger. And experts say that the U.S. is not prepared for an attack.
