Selenium is an essential trace element. It’s often found in antioxidant enzymes, protecting our bodies from oxidative damage.
In biomedicine, a culture is a group of cells grown in a lab. Cultures help us to learn about cellular processes and to test and produce medicines.
Dr. Miriam Meisler has spent decades determining gene functions, identifying genetic variants that cause human disease, and investigating treatments.
Your body is made up of trillions of cells that all originate from just one—a fertilized egg. The massive multiplication of cells after conception is possible thanks to cell division, which occurs when one cell splits into two. Cell division not only enables growth but also replaces damaged or dead cells and makes reproduction possible. …

“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 …

Genes are segments of DNA. They contain instructions for building one or more molecules that help the body work. Researchers in the field of genetics study genes and heredity—how certain traits are passed from parents to their offspring through DNA. NIGMS supports many scientists who investigate the genetics of people and research organisms to better understand …
The tiny roundworm Caenorhabditis elegans is one of the most common research organisms—creatures scientists use to study life. While C. elegans may seem drastically different from humans, it shares many genes and molecular pathways with us. Viewed with a microscope, the worm can also be surprisingly beautiful. Aside from the stunning imagery, these examples from …

But no matter what time of the year, you can see colorful glows in many biology labs. Scientists have enabled many organisms to light up in the dark—from cells to fruit flies and Mexican …
Note to our Biomedical Beat readers: Echoing the sentiments NIH Director Francis Collins made on his blog, NIGMS is making every effort during the COVID-19 pandemic to keep supporting the best and most powerful science. In that spirit, we’ll continue to bring you stories across a wide range of NIGMS topics. We hope these posts …
