When bacteria retain the crystal violet dye during the Gram stain test, they are called Gram-positive bacteria. Learn more here.

A chain reaction similar to how some eels generate electricity could be used in a novel biomedical way to stimulate cells in the human body, researchers at the University of Oxford said.

Learn the differences between gram positive vs gram negative bacteria, including structure, stain results and examples of key bacterial species.

Stem Cell ‘Junk Yards’ Reveal a New Clue About Aging New research shows that the cells’ garbage-clearing function deteriorates with age—and opens the door to reversing the process.
