Meiosis—the formation of egg and sperm cells—is a highly choreographed process that creates genetic diversity in all plants and animals, including humans, to make each of us unique. This kaleidoscopic image shows cells from a worm exchanging DNA during meiosis. You can see a protein-based polymer tether (green) from what’s called the synaptonemal complex. The […]
A big challenge in unlocking the mysteries of aging is how long you need to study humans, or even human cells, to get answers. But, in partnership with NASA, NIH is hoping that space will help facilitate this important area of research.
What looks like a traffic grid filled with roundabouts is nothing of the sort: It’s actually a peek inside a tiny microchamber that models a complex system operating in many of our cells. The system is a molecular transportation network made of the protein actin, and researchers have reconstructed it in the lab to study […]
Whether it’s growing up in gut-wrenching poverty, dealing with dysfunctional family dynamics, or coping with persistent bullying in school, extreme adversity can shatter a child’s sense of emotional well-being. But does it also place kids at higher of developing heart disease, diabetes, and other chronic health conditions as adults?
