Selenium is an essential trace element for humans (1, 2). Biochemical evidence for its importance is demonstrated by its function in the selenoenzymes GPx, which protects cells against oxidative ...

Although present in very small amounts, selenium (Se)-based compounds play important roles in protecting the body from oxidative stress, regulating thyroid hormones, strengthening the immune system, ...

Conditions suitable to support complex life may have developed in Earth's oceans -- and then faded -- more than a billion years before life truly took hold, a new study has found. Conditions suitable ...
