Phys.org / Arctic cloud and ice formation affected by Russian river runoff as region studied for first time
Organic matter carried in rivers to the Russian part of the Arctic Ocean may be creating more clouds and keeping the region cooler, a new study has found.
Phys.org / 5,500-year-old skeleton yields oldest evidence yet of syphilis-related bacteria
Scientists have recovered a genome of Treponema pallidum—the bacterium whose subspecies today are responsible for four treponemal diseases, including syphilis—from 5,500-year-old human remains in Sabana de Bogotá, Colombia. ...
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 / 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 / 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 / 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 / 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 / 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 / Battery-free nano-sensors could pave the way for next-generation wearables
Nano-sensors that work without batteries or wires could pave the way for more comfortable, less obtrusive sleep and health care monitoring at home, according to scientists at the University of Surrey.
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 / 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 / Evidence of 'lightning-fast' evolution found after Chicxulub impact
The asteroid that struck the Earth 66 million years ago devastated life across the planet, wiping out the dinosaurs and other organisms in a hail of fire and catastrophic climate change. But new research shows that it also ...
