Paul Andersen explains the major elements in the endocrine system. He explains how glands produce hormones which target cells. He differentiates between water soluble and lipid soluble hormones. He then describes the hormones and...

It never gets dark anymore. Not REALLY dark, anyway. Not like it used to. Light pollution is not only making it more difficult to see the night sky, but it's also affecting our health. For the past century and a half, since the dawn of...

The biggest (and most mysterious!) migration in the world happens every night in the ocean as 10 billion tons of zooplankton swim to the surface to feed. This undersea journey is known as Diel vertical migration, and it occurs in every...

Every year, hundreds of millions of people voluntarily turn their lives upside down by setting their clocks forward one hour in the spring and back one hour in the autumn on a particular date mandated by the government wherever they...

An early bird rises with the sun, springing out of bed abuzz with energy. Meanwhile, a night owl groggily rises much later, not hitting their stride until late in the day. How many people are truly night owls or early birds? And are our...

Sleep is complicated. And there's still a lot we don't know about it, but zebrafish larvae are a surprisingly good place to look to learn more about what makes us sleepy.

Light pollution -- it's not just the bane of light sleepers and frustrated astronomers. It also is tinkering with the biological cycles of all kinds of living things, including us! SciShow takes you behind the glare to understand the...

There have been a lot of scientific discoveries around COVID, but other science stories did happen in 2020 — including amazing discoveries about everything from dinosaurs to parasites.

If you’ve ever experienced constipation while traveling, don’t worry - you are not alone, and there may be some things you can do to avoid it.

Michael Aranda goes to the barnyard to answer one of the most frequently asked questions about animals: Why do roosters crow? Short answer: Because they're jerks. Longer answer: They're jerks that tend to get noticed more than the other...

Sleep is a crucial activity for our brains to function properly. But when you’re on the ISS, you face a myriad of distractions and obligations that make it difficult to get good shuteye. So how do these astronauts ever get restful sleep?

Paul Andersen explains how organisms regulate timing and control. Phototropism and Photoperiodism allow plants to respond to light throughout the day and year. Circadian rhythms are used in all organisms (including animals) as an...
