Phys.org / Horses with over 30 minutes of REM sleep show better persistence in learning tasks
Just as for humans, sufficient sleep supports learning and coping for horses. A recent study at the University of Helsinki indicates that short periods of REM sleep impair horses' perseverance and performance in demanding ...
Phys.org / Plasma rotation simulations could help fusion reactors survive decades of use
Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the magnetic fields that ...
Phys.org / Renewable biological catalyst carries the potential to transform wastewater into phosphorus resource
Phosphorus is an essential nutrient for plants and managing its availability is critical for growing crops to maintain the global food supply. In an effort to move toward a more sustainable bioeconomy, researchers from the ...
Phys.org / Climbing behaviors of tree-dwelling mammals unlock insights on early primate evolution
Researchers have shed new light on the features that enable tree-dwelling mammals to move effectively through their environments, providing insights into the evolution of the distinct upright postures seen in primates. The ...
Phys.org / Northern Europe's radiator: Volcanic eruptions in the past may have pushed ocean currents toward collapse
New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning Circulation (AMOC), causing temperatures ...
Phys.org / Specially engineered crystal reveals magnetism with quantum potential
Researchers at the Department of Energy's Oak Ridge National Laboratory, working with international partners, have uncovered surprising behavior in a specially engineered crystal. Composed of tantalum, tungsten and selenium—elements ...
Phys.org / Beyond 'survival' of fittest: Evolution works in teams
Survival of the fittest. Nature red in tooth and claw. The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring. ...
Phys.org / Satellite imagery and AI reveal development needs hidden by national data
For years, Iceland, Switzerland, and Norway have ranked near the top of the United Nations' annual index of countries based on indicators of well-being and quality of life. Countries with more poverty and less access to health ...
Phys.org / Intensive grazing and soil fertility favor the growth of non-native plants, drylands study finds
A global study has revealed the conditions under which non-native plants thrive in the world's many dryland regions and the factors that limit their spread. Using data from 98 study sites across 25 countries on six continents, ...
Phys.org / Off-the-shelf components enable deployment-ready quantum entanglement source
Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional polarization-based entanglement states ...
Phys.org / Early study connects dogs' cancer survival with their gut microbiome composition
Canine cancer patients receiving a new form of immunotherapy lived longer or shorter depending on the composition of their microbiome, the community of organisms living in their gut. Results of the clinical trial led by Oregon ...
Phys.org / Quantum sensor research advances the pursuit of dark matter
Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, using quantum optical ...
