We've talked about the trillions of microbes inside you before, but we're learning that these little creatures may have more influence than you thought!

Cyanobacteria and other microbes produce a lot of oxygen. What if we could use that oxygen to power our brains?

When a bunch of cows burp they can exhale a lot of methane that affects the global warming problem. Researchers are working on finding solutions for it.

Ever since humans found out about germs, we’ve gone a bit overboard inventing antibacterial soap and antibiotics and antifungals. But despite our aversion to them, microbes aren’t all bad, and some of them could even help us...

Alcohols are used to disinfect things all the time, which makes drinking them sound bad for the helpful critters in your gut. But, turns out, drinking in moderation could actually be good for your microbiome.

What have we learned from exploring Earth's harshest locations? That pretty everywhere we look for life, we find it. From smoking hot hydrothermal vents to icy deserts, up in clouds and inside rocks, extremophiles have found a way to...

In this collection of classic MinuteEarth videos, we dive into one of our favorite topics, well at least our #2: poop.

It's easy to take waste disposal for granted, so here are six ways modern technology has made your poop safer and less... gross.

Biofuels can provide energy without the reliance on environmentally harmful fossils fuels -- but scientists are still searching for a plentiful source. Craig A. Kohn demonstrates how cellulose, the naturally abundant tough walls of plant...

As powerful as today’s forensic science technologies are, everything can benefit from an upgrade. Today we'll tell you about 6 new techniques scientists are developing to track down suspects, analyze evidence, and even peer inside...

You've probably seen cows enjoying a nice mouthful of grass, but why can't we do the same?

Most of the time you probably don’t have to think too much about your toilet, but billions of people don’t have access to safe sanitation. So, engineers are working on new kinds of toilets that could help solve that!

Between you and the rest of the world lies an interface that makes up 16% of your physical weight. This is your skin, the largest organ in your body: laid out flat, it would cover close to 1.7 square meters of ground. But besides keeping...

With sandwiches and toast, sourdough bread always adds an extra accented flavor to your meals. But where does the signature tartness come from?

Researchers have unlocked the final gaps in the human genome, and what they tell us could mean big waves for the future of medicine.

We’re all excited about the Mars rover Perseverance this week, but scientists are also working on some other exciting things!

Plants are constantly under attack. They face threats ranging from microscopic fungi to small herbivores like caterpillars, up to large herbivores like elephants. But plants are ready, with a whole series of internal and external...

Food doesn't last. In days, sometimes hours, bread goes moldy, apple slices turn brown, and bacteria multiply in mayonnaise. But you can find all of these foods out on the shelf at the grocery store " hopefully unspoiled -- thanks to...

This week, science explains the chemical love-connection we share with our dogs, and how some of the most isolated populations of people in the world are different on the inside.

Why Don't Scavengers Get Sick?

If you’re trying to figure out where to plan on sheltering during the zombie apocalypse, it’s essential to know whether zombies sink or float!

Each year humanity produces roughly 400 million tons of plastic, 80% of which is discarded as trash. Of that plastic waste, only one-tenth is recycled. 60% gets incinerated or goes into the landfills, and 30% leaks out into the...

When life emerged on Earth about 4 billion years ago, the earliest microbes had a set of basic genes that succeeded in keeping them alive. In the age of humans and other large organisms, there are a lot more genes to go around. Where did...
