Phys.org / Aging zoo animals threaten long-term species conservation goals
Many mammal populations in European and North American zoos are aging—a trend that jeopardizes the long-term viability of so-called reserve populations and, with it, a core mission of modern zoos in global species conservation. ...
Phys.org / Study challenges long-held theory that language is built on grammar trees
Every time we speak, we're improvising. "Humans possess a remarkable ability to talk about almost anything, sometimes putting words together into never-before-spoken or -written sentences," said Morten H. Christiansen, the ...
Phys.org / A new optical centrifuge is helping physicists probe the mysteries of superfluids
Physicists have used a new optical centrifuge to control the rotation of molecules suspended in liquid helium nano-droplets, bringing them a step closer to demystifying the behavior of exotic, frictionless superfluids.
Phys.org / New code connects microscopic insights to the macroscopic world
In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches ...
Phys.org / Beneath Antarctica's largest ice shelf, a hidden ocean is revealing its secrets
Beneath Antarctica's Ross Ice Shelf lies one of the least measured oceans on Earth—a vast, dark cavity roughly twice the volume of the North Sea.
Phys.org / Social networks spanned thousands of square kilometers during the Upper Paleolithic period, study finds
Researchers from several European institutions, led by scientists from the University of Barcelona and the University of Alcalá, have demonstrated that the hunter-gatherers who inhabited the interior of the Iberian Peninsula ...
Phys.org / Humans use local dialects to communicate with honeyguide birds, research shows
Researchers from the University of Cape Town (UCT), working with international collaborators, have shown that people in northern Mozambique use regionally distinct "dialects" when communicating with honeyguide birds, revealing ...
Phys.org / Meadows reveal unexpected monotony in insect biodiversity study
According to a new study by the University of Würzburg, Bavarian meadows are the most monotonous insect habitats. Surprisingly, fields and settlements often offer more diversity than grassland.
Phys.org / Experiment clarifies cosmic origin of rare proton-rich isotope selenium-74
Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, called p-nuclei. Led by Artemis Tsantiri, then-graduate student at the Facility for Rare Isotope Beams ...
Phys.org / Resurrected ancient enzyme offers new window into early Earth and the search for life beyond it
By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers at the University of Wisconsin–Madison have created a new way to improve our understanding of the origins of life on Earth ...
Phys.org / Cells that are not our own may unlock secrets about our health
During pregnancy, maternal and fetal cells migrate back and forth across the placenta, with fetal cells entering the mother's bloodstream and tissues. They can settle in maternal organs such as the thyroid, liver, lungs, ...
Phys.org / Tungsten carbide phase control: Engineering a low-cost alternative catalyst for producing sustainable petrochemicals
Important everyday products—from plastics to detergents—are made through chemical reactions that mostly use precious metals such as platinum as catalysts. Scientists have been searching for more sustainable, low-cost ...
