The origin of the first living molecules on our planet has long been debated. However, recent experiments are revealing new ...

A breakthrough experiment, published in the Proceedings of the National Academy of Sciences, offers compelling support for ...

A giant impact on the early Earth could have brought the building blocks of RNA to our planet, which new research suggests ...

With less ATP, your cells begin to age faster and all tissues degenerate more quickly—and that can be especially visible in the skin. “Research suggests that NAD+ helps maintain skin elasticity by ...

Cells possess multiple intracellular Ca2+-releasing systems. Sea urchin egg homogenates are a well-established model to study intracellular Ca2+ release. In the present study the mechanism of ...

What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this mystery. Their experiments show that ribose binds more readily and ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

Ribose (D-ribose) is a natural, simple sugar used as a dietary supplement. It may speed exercise recovery, help with heart conditions, and smooth wrinkles. But with few studies, it's still unclear if ...
