Phys.org / Archaeologists discover unique mosaic patolli board at Guatemalan Maya city
In a study published in Latin American Antiquity, Dr. Julien Hiquet and Dr. Rémi Méreuze analyzed the remains of a unique mosaic-style patolli game board discovered in the Classic Period city of Naachtun, Guatemala.
Phys.org / Ultracold atoms observed climbing a quantum staircase
For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms.
Phys.org / New Guineans and Aboriginal Australians descend from two groups who arrived 60,000 years ago, research suggests
A collaboration between the University of Huddersfield's Archaeogenetics Research Group and the University of Southampton's Center for Maritime Archaeology, has clarified the first settlement of New Guinea and Australia by ...
Phys.org / The gut bacteria that put the brakes on weight gain in mice
The gut microbiome is intimately linked to human health and weight. Differences in the gut microbiome—the bacteria and fungi in the gut—are associated with obesity and weight gain, raising the possibility that changing ...
Phys.org / Fabricating single-photon light sources from carbon nanotubes
Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner by RIKEN researchers. Such carbon nanotubes could form the basis of future quantum technologies ...
Dialog / How sustainability is driving innovation in functionalized graphene materials
Graphene is often described as a wonder material. It is strong, electrically conductive, thermally efficient, and remarkably versatile. Yet despite more than a decade of excitement, many graphene-based technologies still ...
Phys.org / New image sensor breaks optical limits
Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of innovation, a fundamental ...
Phys.org / Glowing urine and shining bark: Scientists discover the secret visual language of deer
During mating season, when male white-tailed deer want to get noticed by the opposite sex and warn off rivals, they rub their antlers against trees and scrape the forest floor. Then they pee on these patches. But there is ...
Phys.org / Observations catch galaxy cluster in the process of merging
Astronomers have used the Keck Observatory's DEIMOS multi-object spectrograph to observe a nearby galaxy cluster designated RXC J0032.1+1808. As a result, they found that the cluster undergoes a major merging event. The finding ...
Phys.org / Scientists boost mitochondria to burn more calories
Researchers have developed experimental drugs that encourage the mitochondria in our cells to work a little harder and burn more calories. The findings could open the door to new treatments for obesity and improve metabolic ...
Phys.org / Mechanism for twisted growth of plant organs discovered
From morning glories spiraling up fence posts to grape vines corkscrewing through arbors, twisted growth is a problem-solving tool found throughout the plant kingdom. Roots "do the twist" all the time, skewing hard right ...
Phys.org / Radio black hole trio lights up in rare galaxy merger
Astronomers have confirmed the first known triple system in which all three galaxies host actively feeding, radio-bright supermassive black holes.
