Neurons are the foundational cells in the nervous system. They pass along and process information using electrical signals.
- Science & Society
When COVID-19 comes for your science fair
When labs shut down due to COVID-19, teens took their science fair projects to the internet and … sometimes even to the bathroom.
- Life
Scientists Say: Hominid
Scientists are still working out what counts as a hominid. Some say it’s just people and our extinct ancestors. Others say add more apes.
- Space
Let’s learn about the moon
