A fetus needs oxygen long before its lungs work and it's exposed to the air. Some ingenious biochemistry explains how the mother's blood delivers it.
The relationship between the coronavirus and human genetics is murky.

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.
Your body wants you to freak out about germs so you avoid them.

Human psychology has evolved to avoid situations that could lead to infection. Behavioral choices now could have long-term effects on how people interact with others and the world.
Testing in cells is an important and exciting first step.

Researchers at the University of California, San Francisco, identified nine existing drugs that show promise to treat COVID-19. The proteins they target haven't been tried before.
Apps that warn about close contact with COVID-19 cases are key to relaxing social distancing rules.

Bluetooth wireless communication makes it possible for people to get alerts on their phones when they've been exposed to the coronavirus. Adding the right cryptography scheme keeps those alerts private.
The steady rate of genetic changes lets researchers recreate how a virus has travelled.
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.
For centuries, indigenous history has been largely told through a European lens.

Modern dating techniques are providing new time frames for indigenous settlements in Northeast North America, free from the Eurocentric bias that previously led to incorrect assumptions.
Using new technology to answer questions about shark reproduction.
Researchers are using a newly developed satellite tag to study previously unknown aspects of tiger shark reproduction. This approach could be used on other difficult-to-study shark species.
Campus shutdowns mean researchers must be classified as essential personnel to tend collections, like these fungus-colonized plants.
From fungi and flies to spiders and fish, living collections need care and feeding even when their human keepers are dealing with a pandemic and its resultant social distancing.
The launch of Hubble Space Telescope on April 24, 1990. This photo captures the first time that there were shuttles on both pad 39a and 39b.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
Many items labeled “Made in China” could be made on people’s desktops instead.

The rush to make personal protective equipment like facemasks and face shields using 3D printers shows that the technology can help circumvent global supply chain disruptions.
The last thing adolescents want is to be trapped at home alone, by order of their parents.

Together the social and emotional 'jobs' of adolescence – developing intimate friendships and achieving autonomy – make teens uniquely resistant to calls for social distancing.
From your lungs into the air around you, aerosols carry coronavirus.

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.

Understanding isolation's effects on regular people, rather than those certified to have 'the right stuff,' will help prepare us for the future, whether another pandemic or interplanetary space travel.

Robots are helping health care workers and public safety officials more safely and quickly treat coronavirus patients and contain the pandemic. They have something in common: They're tried and tested.
