A protein that is a key modulator of fat, glucose and cholesterol levels in the body usually works in tandem with another ...

Inspired by the simple mechanism of a seesaw—when one side goes up, the other side goes down—researchers asked an intriguing question: Could a single molecule switch between two different roles like a ...

How did life originate? Ancient proteins may hold important clues. Every organism on Earth is made up of proteins. Although all organisms—even single-celled ones—have complex protein structures now, ...

In Greek mythology, Proteus, son of Poseidon and prophetic shepherd of sea-beasts, could foretell the future. The elusive sea god was difficult to capture as he assumed many forms—a lion, a serpent, ...

Scientists may have figured out a brand new way to treat lung cancer by using a protein that inhibits tumor growth. This previously unknown molecule pathway could help researchers develop personalized ...

Amyloids are perhaps best known as a key driver of Alzheimer’s disease. The amorphous proteins, found throughout the human body, stick to nerve cells like plaque, choking off their function and ...

Researchers are testing a fundamentally different strategy against neurodegenerative disease: instead of clearing protein deposits after they form, new experimental therapies aim to stop toxic protein ...
