A Roman-era skeleton discovered in southern England has finally given up her secrets after more than a decade of debate. Known as the Beachy Head Woman, she was once thought to have roots in sub-Saharan Africa or the Mediterranean—an idea that sparked global …

Iron is an essential trace element in biological cells. The concentration of the element and its so-called redox state—it can exist either in a doubly ionized state as iron (II) (Fe2+) or a triply ionized state as iron (III) (Fe3+)—play a key role in metaboli…

Researchers have developed a technique that allows them to carve complex three dimensional nanodevices directly from single crystals. To demonstrate its power, they sculpted microscopic helices from a magnetic material and found that the structures behave lik…

A switch from a humid to a dry climate has led the Eastern African Rift Zone to pull apart more freely, new research finds.

Stephen Hawking’s “laws may be decreed by God” remark keeps sparking debate—was it deism, metaphor, or a hard line against miracles?
