Markers of biological ageing in polar bear tissue samples reveal that stress associated with climate change appears to be taking a toll

New research has shown that the tropical subsurface ocean gained oxygen during the Paleocene-Eocene Thermal Maximum (commonly referred to as PETM). During this short-lived interval of time in Earth s history that occurred 56 million years ago the average temperatures rose by up to six degrees within a few thousand years.

Changing the microbial community on the roots of tea plants can improve the flavour and nutritional content of the leaves, leading to a better-tasting cuppa

Different species of poison frogs tap their toes when feeding to create vibrations that cause flies to move closer to them

A new study explores the weight great fossil sites have on our understanding of evolutionary relationships between fossil groups and quantified the power these sites have on our understanding of evolutionary history. Surprisingly, the authors discovered that the wind-swept sand deposits of the Late Cretaceous Gobi Desert's extraordinarily diverse and well-preserved fossil lizard record shapes our understanding of their evolutionary history more than any other site on the planet.

Taken in the Svalbard archipelago, Nima Sarikhani's image has scooped the Wildlife Photographer of the Year People’s Choice Award

Scientists have grown cow muscle cells inside grains of rice to create a new food product that could supply protein with a lower carbon footprint than beef

During courtship rituals, female scorpions appear to willingly let males sting them, which may be a way for them to evaluate prospective mates

Chimpanzees, bonobos, orangutans and gorillas frequently toy with their peers by poking, tickling or stealing from them, perhaps showing behaviours that were prerequisites for human joking

Some pet dogs retain their baby teeth, creating two rows that resemble the mouth of a shark. A new analysis shows that the condition is more prevalent in smaller breeds and obese dogs

Male Brachycephalus pulex frogs are so small that two of them can sit side by side on a pinky nail

The bead found at the La Prele Mammoth site in Wyoming's Converse County is about 12,940 years old and made of bone from a hare.

This study reports widespread mineral carbonation of mantle rocks in an oceanic transform fueled by magmatic degassing of CO2. The findings describe a previously unknown part of the geological carbon cycle in transform faults that represent one of the three principal plate boundaries on Earth. The confluence of tectonically exhumed mantle rocks and CO2-rich alkaline basalt formed through limited extents of melting characteristic of the St. Paul's transform faults may be a pervasive feature at oceanic transform faults in general. Because transform faults have not been accounted for in previous estimates of global geological CO2 fluxes, the mass transfer of magmatic CO2 to the altered oceanic mantle and seawater may be larger than previously thought.

Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.

Snail shells are often colorful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed. Residues of ancient color patterns are therefore very rare. This makes a new discovery all the more astonishing: researchers found pigments in twelve-million-year-old fossilized snail shells.
