The part of your cells that helps you recover from a hangover is shaped like a maze of tubes and is made of two parts — the rough endoplasmic reticulum and the smooth endoplasmic reticulum.

What's the Difference Between Prokaryotic and Eukaryotic Cells?

Prokaryotic cells are like single-room efficiency apartments while eukaryotic cells are like mansions with many rooms — and they are the only two kinds of cells in the world.

Plankton Is Earth's Tiniest Unsung Hero

A single-celled algae, barely visible to the eye, plankton contributes to some of the world's most important resources and is essential to the food chain that supports all life.

Can You Live Without Oxygen? This Animal Can

You could be excused for thinking that, of course, all animals breathe oxygen to live. Because it wasn't until very recently that scientists discovered the only multicellular animal that doesn't. Meet Henneguya salminicola.

How Viruses Work

Influenza, Ebola and COVID-19 are all viruses. Find out what a virus does to your body and how to decrease your chance of exposure.

How Long Can Viruses Live on Surfaces?

Viruses need hosts to replicate and reproduce. So if a virus has no host, how long can it survive? It depends on a lot of factors.

Chloroplasts Are the Plant Cells That Manufacture Energy

Chloroplasts are where some of the most miraculous chemistry on Earth goes down.

How Close Are We to Creating a Universal Blood Type?

Blood transfusions are required in the U.S. every two seconds. That's why the research from the Withers Lab, which converted Type A blood to universal donor blood using bacteria, is so groundbreaking.

How Photosynthesis Captures Light and Powers Life on Earth

No life, except possibly very small bacteria, would exist on Earth without photosynthesis.

The Fungi Amongi Are the Great Decomposers

Yep, fungi are all around us — in the grocery store, in the woods or living on your discolored toenail. And fungi can break down almost anything.

How Free Radicals Affect Your Body

When an electron loses its partner, it creates a free radical. So is that free radical now potentially hazardous to your health?

Here's How Plant and Animal Cells Are Different

While plant and animal cells are strikingly similar, the main difference between them is that plant cells are able to create their own food and animal cells cannot.

Men's Beards Carry More Bacteria Than Dogs' Fur, Study Suggests

While researchers can't say from this small study whether hairy men are inherently germier than the rest of the human race, the results are startling.
