Cortisol is a hormone that helps humans and many other animals regulate their energy use and respond to changing conditions. For a long time, sharks and rays were believed to rely on a different steroid hormone for these ...
A protein complex known as DREAM that normally puts the brakes on genes may also be crucial for reproduction in plants, according to new research published in Science Advances.

Changes in our genes affect health risks from heart disease to cancer, but how those genes are turned on and off is just as crucial to health. What's more, almost all genes occur as two copies—one from each parent—that aren't ...

Proteases are naturally occurring enzymes that break down proteins into peptides and even single amino acids. They are useful in medicine and industrial processes, where they clean tissue, digest waste and help in the manufacture ...
As an embryo develops from a small cluster of stem cells, those once "blank slate" cells begin to take on more specialized roles like brain, liver or muscle cells and organize themselves into three-dimensional structures ...
