Longevity science has spent decades chasing single molecules that might slow aging, but most candidates have delivered modest ...

Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Scientists have long been trying to tease apart hepatitis A virus, to understand its inner workings and how it functions in the human body. Infectious disease researchers have discovered that a little ...

Proteins need to fold into specific shapes to perform their functions in cells, but they occasionally misfold, which can ...
