How many mantises do you see in this image? The two mantises shown are among the largest and smallest of all mantises. While they seem to be getting along fine, most mantises like to keep to ...

This furry ring is a compilation of 50 neurons in the fruit fly brain that help the fly navigate. Recent research shows that when the fly changes course, different sections of this ring activate, ...

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries the information contained within DNA to the ribosomes, where the genetic information is synthesized into ...

This video lets you peek inside the human brain, highlighting the neuronal fibers that enable communication across the brain. This communication is vital to all brain functions, including learning, ...

This vivid chameleon embryo has been stained to highlight the bones and cartilage of its skeleton. You can also see some of its developing internal organs. This vivid chameleon embryo has been stained ...

Confetti mice are very useful in research because they allow scientists to track which cells produce which proteins based on their color under a fluorescent microscope. These mice are particularly ...

Actin proteins group together to form a network of thin filaments that spread throughout eukaryotic cells. These filaments are involved in giving the cell its structure, allowing the cell to move, and ...

Unlike prokaryotic cells, all eukaryotic cells have nuclei. Nuclei house most of a cell’s genetic information – much of it in the form of DNA – making a nucleus a sort of blueprint for building future ...

You may think of the small intestine as a smooth tube that winds its way through your abdomen. But if you were to look really closely at the inside of the intestine, you would see that it is lined ...

Imagine going to the dentist with this set of teeth! These are teeth located on a snail’s “tongue,” or radula, also called a rasper, which is constantly licking the ground to scrape up and transport ...

Some adult neurons have projections that are amazingly long – thousands of times the length of their cell bodies in some cases. This means that during development, the growing cells need to be able to ...
