Researchers may have answered one of space science's long-running questions -- and it could change our understanding of how life began. Carbon-rich asteroids are abundant in space yet make up less than 5 per cent of meteorites found on Earth.

Microplastics and the much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in organs, blood and other body fluids. Scientists have ...

A new study has shed unprecedented light on the highly variable and climate-sensitive routes that substances from Siberian rivers use to travel across the Arctic Ocean. The findings raise fresh concerns about the increasing spread of pollutants and . ...

Footprints of armored dinosaurs with tail clubs have been identified, following discoveries made in the Canadian Rockies. The 100-million-year-old fossilized footprints were found at sites at both Tumbler Ridge, BC, and northwestern Alberta.

CT scans may account for 5% of all cancers annually, according to a new study that cautions against overusing and overdosing CTs. The danger is greatest for infants, followed by children and adolescents. But adults also are at risk, since they are .. ...

A team of researchers reported the first direct observation of a surprising quantum phenomenon predicted over half a century ago known as a superradiant phase transition, which occurs when two groups of quantum particles begin to fluctuate in a ...

Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create unique patterns. The way the light behaves ...

For the highly populated coastal country of Bangladesh, once-in-a-century storm tides could strike every 10 years -- or more often -- by the end of the century, scientists report.

Using electrodes in a fluid form, researchers have developed a battery that can take any shape. This soft and conformable battery can be integrated into future technology in a completely new way.

Earth's rocky layers are mysteriously low in nitrogen compared with carbon and argon. A scientific team explored our planet's molten youth using advanced quantum mechanical simulations, revealing nitrogen's secret: under extreme pressure, it chose to ...
