Phys.org / Ancient bird routes mapped via plant diversity
It's not what they intended to do or expected to find. They're not even all that interested in birds. When Andre Naranjo and his colleagues began work on a new study published in the Botanical Journal of the Linnean Society, ...
Phys.org / Physicists achieve near-zero friction on macroscopic scales
For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led by Quanshui Zheng at ...
Phys.org / Can a bird be an illegal immigrant? How the White Australia era influenced attitudes to the bulbul
In early January, authorities from South Australia's Department of Primary Industries took to the streets of Adelaide on the hunt for a suspicious individual.
Phys.org / Ultra-thin metasurface can generate and direct quantum entanglement
Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a variety of tasks. An ongoing ...
Phys.org / Invasive termites threatening homes in Florida are spreading farther than predicted
Florida's coastal and urban counties continue to see the spread of two invasive termite species beyond South Florida. The species are now threatening structures statewide, according to a new University of Florida study.
Phys.org / Blood tests in young bald eagles track PFAS pollution across Wisconsin River sites
It hadn't been a successful morning for the Great Lakes Eagle Health team. Traveling by boat, truck, and foot, the team was searching for active eagle nests along the Wisconsin River in Nekoosa, Wisconsin. Tree one was a ...
Phys.org / Scientists explain why methane spiked in the early 2020s
A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land increased atmospheric methane at an unprecedented rate in the early 2020s, an international ...
Tech Xplore / Decoding the shadows: Vehicle recognition software uncovers unusual traffic behavior
Researchers at the Department of Energy's Oak Ridge National Laboratory have developed a deep learning algorithm that analyzes drone, camera, and sensor data to reveal unusual vehicle patterns that may indicate illicit activity, ...
Phys.org / Global map catalogs 459 rare continental mantle earthquakes since 1990
Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth's crust but in our planet's mantle, the layer sandwiched between the thin crust and Earth's molten core. The new ...
Phys.org / Norway's Sami population posed an enigma for the occupying Nazis, researcher says
Historian and Ph.D. research fellow Andreas Eliassen Grini at the Norwegian University of Science and Technology (NTNU) has delved into German soldiers' descriptions of their experiences in Northern Norway. This includes ...
Medical Xpress / Sweet reset: How sugar tastings help the brain quiet old memories
Memories must be flexible so animals can adapt when the world changes. FMI neuroscientists have found that in fruit flies, simply tasting a sugar reward again can weaken all previous associated memories. This process may ...
Phys.org / Study strengthens the potential of mycoprotein as an alternative to meat
Plant-based food as an alternative to meat is high on the agenda today, and mycoprotein (fungal protein) in particular has come into focus in recent years. A new doctoral thesis from the University of Borås in Sweden, has ...
