How Brain Cells Talk
to Each Other
By Florence Roberts,
PhD, RN
For your brain to function, nerve cells called neu-rons, must "talk" to each other. But they talk with chemi-cals, not words. Let’s ask Nate Neuron how neurons "talk."
Nate Neuron"Hi, I’m Nate Neuron. I have a big belly called a cell body.It makes chemicals, generates energy, stores my genes (which carry inherited information), and, in gen-eral, keeps me alive. Attached all around my cell body are branches, like tiny trees, called dendrites. On one side of the cell body is a special long extension called an axon. We’ll meet them both, but let’s meet Denny Den-drite first." READ MORE...

The deepest parts of our oceans are among the least explored and most unknown places on Planet Earth. Through the use of submarines and remotely operated devices, scientists are discovering what life exists in the deep ocean.
In the latest issue of Science in the News, students learn about what movie director James Cameron (Avatar, Titanic, and more) saw on his recent dive into the Challenger Deep near Guam.
And, as if this were not deep enough, we also share what scientists are finding by using remote probes that actually snoop BENEATH the ocean's floor!
As many have come to expect with our monthly issue of SITN, discussion questions, vocabulary, and activities are included with the short text to help students not only understand the topic, but to also infer new knowledge. We believe that as students improve their grasp of science vocabulary, their interest in science grows dramatically.
As a premium member, Science in the News is included for downloading, as is all of our wide selection of Spigot content.

| Carbohydrates |
| Carbohydrates are molecules made of carbon, hydrogen, and oxygen. Carbohydrates, also known as sugars, provide energy for a cell inside its mitochondria. |
| Proteins |
| Proteins are large molecules known as ribosomes in the cell’s organelles. Proteins are used by cells for structural support, transporting other products, and sending signals. |

Cells are the building blocks of all plants and animals. Plants are made of many different types of cells. Each cell has a specific purpose so that the plant can function properly. Just as with animals, all of the plant cells work together as a whole to make the plant come to life.
A plant has parts such as flowers, stems, leaves, and roots. Different cells make up each of these plant parts. Each cell plays a vital role to sustain the life cycle of the plant. READ MORE...
