Phys.org / Wastewater management reverses widespread freshwater deoxygenation in China
Freshwater ecosystems worldwide have been suffering from declining oxygen levels—a trend known as deoxygenation—that threatens biodiversity, fisheries and ecosystem stability. However, a new study published in Nature Geoscience ...
Phys.org / Human sacrifice in Inca Empire may have been driven by political motives, not religion
Three decades ago, researchers working atop the Llullaillaco volcano, located on the border between Argentina and Chile, discovered exceptionally well-preserved remains. The find included the mummified bodies of three children ...
Medical Xpress / Multiple sclerosis impacts daily life far beyond its physical symptoms, new study finds
Multiple sclerosis (MS) can have a substantial impact on many aspects of life beyond physical health, with 51% of people reporting that the disease affects their social life and 48% reporting that it affects their work, according ...
Phys.org / Whitebait rapidly switch life cycles when earthquakes cut off route to sea
Aotearoa New Zealand whitebait can rapidly switch their life cycles in response to sudden environmental changes, new University of Otago—Ōtākou Whakaihu Waka research shows. The research is published in the journal Nature ...
Phys.org / Apes and humans have been sharing a laugh for 15 million years
Great apes may have been laughing with a similar rhythm to modern humans for at least 15 million years, a University of Warwick study reveals. The finding offers unexpected clues to how human speech evolved.
Phys.org / Laser-based 3D imaging system enables precise detection and quantification of methane leakage
A research team led by Prof. Zhang Zhirong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a high-performance laser-based three-dimensional methane gas cloud imaging telemetry ...
Phys.org / Interlayer self-doping could unlock room-temperature multiferroics in atom-thin materials
Multiferroics are materials that exhibit more than one prominent "ferroic" property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic ...
Phys.org / Why female guppies prefer rare males and how this might shape evolution
When it comes to choosing a partner, some species prefer males that stand out from the crowd. Evolutionary biologists call the resulting process negative frequency-dependent selection. It means that a male has a huge mating ...
Medical Xpress / Existing drugs could be repurposed for longevity by tapping network of aging-related genes
The quest to prolong life has gone on for as long as human existence itself, from the mythical Fountain of Youth to quick-fix fads like intermittent fasting, supplements and injections. But if you take a look in your medicine ...
Phys.org / ALMA spots a nine-member stellar family in the act of formation
Massive stars much bigger than our sun always come in pairs or groups, not alone. But astronomers don't fully understand how these groupings form. In a new study, astronomers using ALMA have serendipitously discovered a young ...
Phys.org / How bacteria use circadian clocks to colonize their world
Research has revealed how bacteria rely on circadian clocks to control the spread of their multicellular colonies. The findings provide important clues as to how we might improve soil health and plant growth. They may also ...
Medical Xpress / Blood vessel cells keep fixed signaling roles for weeks, reshaping view of capillary communication
The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have known about this signaling ...
