Mapping the Milky Way's magnetic field in 3D

We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed an ingenious way to measure ...

Scientists discover higher levels of CO₂ increase survival of viruses in the air and transmission risk

A new study has revealed for the first time the vital role carbon dioxide (CO2) plays in determining the lifespan of airborne viruses—namely SARS-CoV-2, the virus that causes COVID-19. It clearly showed keeping CO2 levels ...
