Fossils

DNA analysis of remains found at medieval sites has identified closely related strains of leprosy-causing bacteria in the bones of humans and a red squirrel

Simulations of the crust of early Earth show that cycles of pressure caused by geysers or tidal forces could have generated cell-like structures and even very simple proteins

Migrating flies can carry pollen hundreds or thousands of kilometres, and this could help plants adapt to climate change

Plants are often celebrated for the parts that are easy to see – flower, leaves, fruit – but scientists are uncovering the secrets of their more mysterious underground networks

Climate change could be fueling bumblebee population loss by making hives too hot to handle

A male Sumatran orangutan chewed the leaves of a plant used in Indonesian traditional medicine and placed them on a wound on his face

Digging sand or grit into clay soils is a drainage fix that has been around for years, but James Wong turns to nature to find a less backbreaking solution

From an orchid bee to a violet carpenter bee, these images show the insects in amazing detail

A research team has found that ancient rocks and fossils from long-extinct marine reptiles in Angola clearly show a key part of Earth's past -- the splitting of South America and Africa and the subsequent formation of the South Atlantic Ocean.

Researchers have provided new age estimates and revised provenance information for the Liujiang human fossils, shedding light on the presence of Homo sapiens in the region. Using advanced dating techniques including U-series dating on human fossils, and radiocarbon and optically stimulated luminescence dating on fossil-bearing sediments, the study revealed new ages ranging from approximately 33,000 to 23,000 years ago. Previously, studies had reported ages of up to 227,000 years of age for the skeleton.

A bristly bump on some mantises’ chests is a never-before-seen “gustifolium”, which may have evolved to help the insects with their highly specialised lifestyles

How did North America's saber-toothed cats hunt without breaking their unwieldy saber-like canines, which are vulnerable to sideways bending stresses? A paleontologist provides mechanical evidence that during adolescence, when young cats were learning to hunt, their baby teeth remained in place for up to 30 months to laterally buttress the emerging permanent sabers. By the time the baby teeth fell out, presumably the adult cat knew how to protect its sabers during attacks.

Red foxes and Arctic foxes dive headfirst into snow at up to 4 metres per second to catch small rodents, and the shape of their snouts reduces the impact force

Dinosaurs were likely as smart as reptiles but not as intelligent as monkeys.

Commercial bowhead whaling ended in the early 20th century, but the industry’s lasting effects on the whales’ genetic diversity are leading to declines again

Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor where a ballcourt was built.
