Atmospheric nitrogen dioxide (NO2) is a hazardous pollutant with profound effects on air quality, climate, and the biosphere. While satellites have been mapping NO2 concentrations since the 1990s, their resolutions have generally been too coarse to identify individual sources such as power plants. A recent study has made significant strides in air pollution monitoring by using imagery from

A team of researchers, including scientists from the University of Oxford, has uncovered a new species of mollusc dating back 500 million years. Named Shishania aculeata, this fossil reveals that the earliest molluscs were flat, shell-less slugs protected by spiny armor. These findings are published in the journal Science. The discovery comes from well-preserved fossils found in eastern Yu

A newly developed timeline of early animal fossils reveals a link between sea levels, changes in marine oxygen, and the appearance of the earliest ancestors of present-day animals. The study reveals clues into the forces that drove the evolution of the earliest organisms, from which all major animal groups descended. A team from the University of Edinburgh studied a compilation of ro
