Pathways: The Anesthesia Issue
Cover of Pathways student magazine. NIGMS and Scholastic bring you Pathways: The Anesthesia Issue, which explores pain and the science behind anesthesia—the medical treatment that prevents patients from feeling pain during surgery and other procedures. Without anesthesia, many life-saving medical procedures would be impossible. Pathways, designed for students in grades 6 through 12, aims to …
Anesthesia and Brain Cells: A Temporary Disruption?

Anesthetic drugs are vital to modern medicine, allowing patients to undergo even the longest and most invasive surgeries without consciousness or pain. Unfortunately, studies have raised the concern that …

Pump Up the Potassium
Potassium is the primary regulator of cells’ pressure and volume, and it plays a part in nerve transmission, muscle contraction, and more.
Science Snippet: RNA’s Remarkable Roles
RNA molecules are integral to protein building and other cellular processes. They also have potential to help prevent, diagnose, and treat disease.
In Other Words: Some Antagonists Are Heroes
In biology, an antagonist is a molecule that binds to a cellular receptor to prevent a response. Some antagonists are important medicines
Science Snippet: Get to Know Your Nerve Cells!
Nerve cells, also known as neurons, carry information through our bodies using electrical impulses and chemical messengers called neurotransmitters. A nerve cell’s size and shape depend on its role and location, but nearly all nerve cells have three main parts:
Science Snippet: Brush Up on Biofilms
A biofilm is a highly organized community of microorganisms that develops naturally on certain surfaces. Typically, biofilms are made up of microbes and an extracellular matrix that they produce. This matrix can include polysaccharides (chains of sugars), proteins, lipids, DNA, and other molecules. The matrix gives the biofilm structure and helps it stick to a …
Biology Beyond the Lab: Using Computers to Study Life
“You’re not going to be able to do biology without understanding programming in the future,” Melissa Wilson, Ph.D., an associate professor of genomics, evolution, and bioinformatics at Arizona State University, said in her 2019 NIGMS Early Career Investigator Lecture. “You don’t have to be an expert programmer. But without understanding programming, I can assert you …
