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 now been able to develop a method for detecting...

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.

Deep sea mining operations are expected to increase the negative impact on environmental indicators by up to 13 per cent, a change categorized as having 'great' significance, relative to the 'without' DSM scenario, notably through increased coastal vulnerability, pollution, and biodiversity loss.

Engineers have created a sophisticated computer model that tracks how water moves in estuaries -- which is critical for evaluating climate variability and sea level fluctuation impacts for coastal communities.

Virginia Tech researchers seek to understand the environmental factors that influence the distribution of hantavirus in rodent populations across the United States.

Every year, thousands of tons of brown algae are extracted from the seabed to obtain compounds such as alginates, a polymer composed of sugars that has high density and strength, offering potential biotechnological applications. An international team has deciphered the mechanism by which a type of enzyme, called alginate lyase...

The United Nations organization responsible for international marine shipping today approved new emission reduction policies. A new paper highlights the need. Researchers surveyed 149 marine shipping experts in 2021 and found they expect the sector to see a reduction of 30 to 40 per cent in the carbon intensity of...

A novel paper is widening understanding of how species interact within ecosystems via the so-called 'Internet of Nature.' The paper reveals that species not only exchange matter and energy but also share vital information that influences behavior, interactions, and ecosystem dynamics -- revealing previously hidden characteristics of natural ecosystems.

Study reveals commonly detected environmental levels of clobazam -- a medication often prescribed for sleep disorders -- increased the river-to-sea migration success of juvenile salmon in the wild. The research team employed slow-release pharmaceutical implants and animal-tracking transmitters to monitor how exposure to clobazam and the opioid painkiller tramadol --...

In a cave overlooking the ocean on the southern coast of South Africa, archaeologists discovered thousands of stone tools, created by ancient humans roughly 20,000 years ago. By examining tiny details in the chipped edges of the blades and stones, archaeologists are able to tell how the tools were made...
