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 ...

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 ...

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 ...

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 ...

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. ...

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, ...

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 ...

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 ...

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 ...

Understanding what complex chemical measurements reveal about materials and reactions can take weeks or months of analysis. But now, an AI-powered platform developed by researchers at the Department of Energy's Lawrence Berkeley ...

Industrial yeasts are a powerhouse of protein production, used to manufacture vaccines, biopharmaceuticals, and other useful compounds. In a new study, MIT chemical engineers have harnessed artificial intelligence to optimize ...

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 ...
