Phys.org / How we unlocked the secrets of Denmark's oldest plank boat—with the help of an ancient fingerprint
About 2,400 years ago, before the emergence of the Roman empire, a small armada of boats approached the island of Als off the coast of southern Jutland in modern-day Denmark. The armada carried around 80 warriors armed with ...
Phys.org / Iron minerals' hidden chemistry explains how soils trap carbon
While scientists have long known that iron oxide minerals help lock away enormous amounts of carbon—sequestering it from the atmosphere—a new Northwestern University study now reveals exactly why these minerals are such ...
Phys.org / Social connections slow aging in dolphins, echoing patterns seen in humans
Male bottlenose dolphins that form friendships age more slowly than loners, new research shows.
Phys.org / Climate change can affect human diseases in widespread and varied ways
As the planet edges towards 1.5°C of global warming, a new study led by the Natural History Museum, London has revealed that scientists still have only a limited understanding of how climate change is reshaping the risk ...
Phys.org / Backyard insect inspires large-scale invisibility particles production
When most people see a leafhopper in their backyard garden, they notice little more than a tiny green or striped insect flicking from leaf to leaf. But these insects are actually master engineers, capable of building some ...
Phys.org / Clues to the origin of hot Jupiters hidden in their orbits
The first exoplanet ever discovered in 1995 was what we now call a "hot Jupiter," a planet as massive as Jupiter with an orbital period of just a few days. Today, hot Jupiters are thought to have formed far from their stars—similar ...
Phys.org / Algae-based asphalt binder strengthens roads for cold climates
Snow and ice can damage paved surfaces, leading to frost heaves and potholes. These become potential hazards for drivers and pedestrians and are expensive to fix. Now, researchers propose in ACS Sustainable Chemistry & Engineering ...
Phys.org / Portable optical scanner reveals hidden ozone damage in plant leaves
Escalating pollution and contamination of water and soil are emerging as serious threats to plant growth and its overall health. Plants are exposed to environmental pollutants for extended periods and exhibit changes in their ...
Phys.org / How do corals feed? Energy supply from directly ingested food previously underestimated
Corals obtain energy in two ways: firstly, through photosynthesis by their symbiotic algae, and secondly by taking up small food particles such as plankton directly from the water. In scientific terms, this process is known ...
Phys.org / Light-driven process forms flexible electrodes on skin, textiles and glass
Visible light can be used to create electrodes from conductive plastics completely without hazardous chemicals. This is shown in a new study carried out by researchers at Linköping and Lund universities, Sweden. The electrodes ...
Phys.org / Modulating key interaction prevents virus from entering cells
Washington State University researchers have found a way to modulate a common virus protein to prevent viruses from entering cells where it can cause illness, a discovery that could someday lead to new antiviral treatments.
Phys.org / Eco-friendly solution to marine fouling uses electrochemically-active coating
Marine fouling triggers ongoing economic losses for the global shipping industry through detrimental effects on structures and vessels—but tests by Flinders University researchers on a new type of anti-foul coating reveal ...
