Phys.org / Dragonfly aerial fights follow some simple rules
Dragonflies are renowned for their remarkable flying abilities. Male dragonflies often compete for territory and mating opportunities, engaging in fascinating in-flight battles. Researchers at Imperial College London and ...
Phys.org / Centuries before farming, hunter-gatherers introduced fish to the Norwegian mountains
Archaeologists have uncovered the remains of 7,000-year-old fish traps in the mountains of southern Norway, indicating that fish were intentionally introduced to upland lakes by Mesolithic hunter-fisher-gatherers and showing ...
Phys.org / A century-old stellar mystery may finally have an explanation
For more than a century, astronomers have puzzled over a strange discrepancy in the historical record. Theta Eridani, a modest star in the constellation Eridanus, is the third-brightest star in its constellation, with a magnitude ...
Phys.org / Generating red blood cell-like cells from canine induced pluripotent stem cells
Blood transfusions are crucial in human and veterinary medicine, yet human blood reserves are in constant need of donors, while blood bank systems in veterinary care are nearly nonexistent. This leaves canine transfusions ...
Phys.org / How the sun goes to 'sleep' could reveal future space weather when it wakes
Scientists have developed a new way to predict the strength of the sun's next activity cycle up to seven years before it reaches its peak.
Phys.org / Samples reveal how Earth slows solar wind striking moon's near side
The moon has been bathed in solar wind for billions of years, but the two hemispheres are struck by solar wind of different speeds and energies.
Phys.org / Quantum entanglement without transport: Leaky qubits offer route around noisy channels
The inevitable leakage of energy and information from a quantum system into its surrounding environment is the enemy of quantum technology. Now, researchers have demonstrated that it can be exploited to generate entanglement—the ...
Phys.org / AirPods-sized fluorescence analytical device holds promise for timely home molecular testing
Advances in medical technology have improved health in part by bringing key aspects of care, once difficult to access, into the home. Tracking symptoms and even screening for certain types of illness outside of a laboratory ...
Phys.org / Observations investigate the nature of a peculiar supernova
An international team of astronomers has performed follow-up observations of a peculiar Type Ia supernova designated SN 2023vjh. Results of the observational campaign, published July 9 on the preprint server arXiv, deliver ...
Phys.org / Researchers develop methods for breaking down forever chemicals
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed two processes—hydrodynamic cavitation and cold atmospheric plasma combined with gas dispersion—to break down per- and polyfluoroalkyl substances ...
Phys.org / Wildfire haze hangs over eastern US—and World Cup final
Heavy, acrid wildfire smoke blanketed much of the eastern United States on Saturday, marring preparations for the weekend's highly anticipated World Cup final to be held in an open stadium in New Jersey.
Phys.org / Nanoparticles could remove harmful immune molecules from blood
The immune system, the body's defense network against infections and injuries, can sometimes become too active. In these cases, it can produce too many immune mediators, fragments of genetic material or proteins that regulate ...
