The largest-ever fossil of a giant millipede -- as big as a car -- has been found on a beach in the north of England.

An unknown culprit has been removing oxygen from our atmosphere for at least 800,000 years, and an analysis of air bubbles preserved in Antarctic ice for up to 1.5 million years has revealed the likely suspect.

A new synthesis reveals mismatches between above- and below-ground plant phenology due to climate change. These findings are important to understand the consequences of climate change on terrestrial biodiversity.

A new study has cast new light on how to best combine antibiotics and phage therapy. Researchers conducted laboratory experiments on Pseudomonas aeruginosa a bacterium which causes disease in immunocompromised and cystic fibrosis patients. They exposed the bacterium to eight types of antibiotics -- and found differences in the mechanisms...

Researchers described for the first time the structure of a bifunctional protein, called CcsBA, that transports heme and attaches it to cytochromes. The study captured two conformational states of CcsBA, a bacterial and chloroplast protein, allowing scientists to characterize the enzyme mechanism.

A study investigated the enigma of why sauropod fossils are only found at lower latitudes, while fossils of other main dinosaur types seem ubiquitously present, with many located in the polar regions.

Despite its prior status as a luxury commodity, silver became widely used for coinage in the Roman world from the 7th century BCE onward and provided a standardized monetary system for ancient Mediterranean civilizations. However, the sources of silver used to produce Roman coinage have largely been used up, making...

Forest restoration treatments can reduce future fire severity and benefit populations of California spotted owls, even with temporary disruptions within owl habitats in the Sierra Nevada, CA.

Scientists have completed the sequences for the coast redwood and giant sequoia genomes. The research helps better explain the genetic basis for these species' ability to adapt to their changing environments. The findings indicate that the coast redwood genome evolved from a single ancestral species.

Canopy soils that form on tree branches contain three times more carbon than soils on the ground in Costa Rica, potentially serving as an important carbon sink around the world.
