The popular diabetes drug metformin has been used for decades — and scientists just figured out its main mechanism (opens the original)
Read excerpt
There are many theories as to how the diabetes drug metformin lowers blood sugar levels, but now, scientists think they've discovered the main route. It turns out that the drug, primarily used in type 2 diabetes, forces gut cells to absorb and burn extra glucose.

Now, scientists wonder whether the structures were present at life's beginning. According to an idea known as the RNA world hypothesis, RNA-based life-forms preceded modern ones that use DNA and protein. RNA, a molecular cousin of DN
