Researchers discovered that living horsetails act like natural distillation towers, producing bizarre oxygen isotope signatures more extreme than anything previously recorded on Earth—sometimes ...

Ancient horsetail plants produce water with unusual oxygen isotopes, offering scientists a new tool to reconstruct Earth’s climate history and understand humidity patterns from millions of years ago.

A new study provides the first comprehensive global estimates of the amount of water stored in Earth's plants and the amount of time it takes for that water to flow through them. The information is a ...
