Apical periodontitis, a chronic and hard-to-treat dental infection, affects more than half of the population worldwide and is the leading cause of tooth loss. Root canal is the standard treatment, but existing approaches ...
In 2019, Caltech researchers demonstrated a new method to use light to control active matter—a kind of material made up of individual energy-consuming pieces that act as a whole to create mechanical motion. The process works ...
Northwestern Medicine scientists have discovered new details about how the human genome produces instructions for creating proteins and cells, the building blocks of life, according to a pioneering new study published in ...
For many years, it was widely believed that fossils no longer contained any original organic molecules as the fossilization process was thought to destroy them.
Hidden within our bones, marrow sustains life by producing billions of blood cells daily, from oxygen-carrying red cells to immune-boosting white cells. This vital function is often disrupted in cancer patients undergoing ...
As space travel gains traction and astronauts spend increasing amounts of time in space, studying its effects on health has become increasingly critical.
It's difficult to know what birds "think" when they fly, but scientists in Australia and Canada are getting some remarkable new insights by looking inside birds' heads.
As an embryo grows, there is a continuous stream of communication between cells to form tissues and organs. Cells need to read numerous cues from their environment, and these may be chemical or mechanical in nature. However, ...
In a new publication in Nature Communications, Israeli and Palestinian engineers from The Hebrew University of Jerusalem pioneered the use of metamaterials to create whole cuts of meat. The work leverages cutting-edge materials ...
Just like your body has a skeleton, every cell in your body has a skeleton—a cytoskeleton to be precise. This provides cells with mechanical resilience, as well as assisting with cell division. To understand how real cells ...
