Published First high mountain settlers at the start of the Neolithic already engaged in other livestock activities apart from transhumance
(via sciencedaily.com) Original source An archaeological find in the Huescan Pyrenees allowed researchers to identify for the first time livestock management strategies and feeding practices which demonstrate how the first high mountain societies, at the start of the Neolithic period, were already carrying out complex livestock and farming activities, instead of being limited to the transhumance of sheep and goats.
Published Blue PHOLEDs: Final color of efficient OLEDs finally viable in lighting
(via sciencedaily.com) Original source Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours. The new phosphorescent OLEDs, commonly referred to as PHOLEDs, can maintain 90% of the blue light intensity for 10-14 times longer than other designs that emit similar deep blue colors. That kind of lifespan could finally make blue PHOLEDs hardy enough to be commercially viable in lights that meet the Department of Energy's 50,000-hour lifetime target. Without a stable blue PHOLED, OLED lights need to use less-efficient technology to create white light.

Published Rise of archery in Andes Mountains dated to 5,000 years ago -- earlier than previous research
(via sciencedaily.com) Original source Focusing on the Lake Titicaca Basin in the Andes mountains, anthropologists found through analysis of 1,179 projectile points that the rise of archery technology dates to around 5,000 years ago. Previous research held that archery in the Andes emerged around 3,000 years ago. The new research from UC Davis indicates that the adoption of bow-and-arrow technology coincided with both the expansion of exchange networks and the growing tendency for people to reside in villages.
Published Large language models validate misinformation
(via sciencedaily.com) Original source In a recent study, researchers systematically tested an early version of ChatGPT's understanding of statements in six categories: facts, conspiracies, controversies, misconceptions, stereotypes, and fiction.
Published Clinicians could be fooled by biased AI, despite explanations
(via sciencedaily.com) Original source A new study finds that clinicians were fooled by biased AI models, even with provided explanations for how the model generated its diagnosis.
Published Artificial intelligence can predict events in people's lives
(via sciencedaily.com) Original source Artificial intelligence can analyze registry data on people's residence, education, income, health and working conditions and, with high accuracy, predict life events.
Published Researchers, Coast Salish people analyze 160-year-old indigenous dog pelt in the Smithsonian's collection
(via sciencedaily.com) Original source A new analysis sheds light on the ancestry and genetics of woolly dogs, a now extinct breed of dog that was a fixture of Indigenous Coast Salish communities in the Pacific Northwest for millennia. Anthropologists and biologists analyzed genetic clues preserved in the pelt of 'Mutton,' the only known woolly dog fleece in the world, to pinpoint the genes responsible for their highly sought-after woolly fur. The study's findings include interviews contributed by several Coast Salish co-authors, including Elders, Knowledge Keepers and Master Weavers, who provided crucial context about the role woolly dogs played in Coast Salish society.
Published AI provides more accurate analysis of prehistoric and modern animals, painting picture of ancient world
(via sciencedaily.com) Original source A new study of the remains of prehistoric and modern African antelopes found that AI technology accurately identified animals more than 90% of the time compared to humans, who had much lower accuracy rates depending on the expert.
Published Interactive screen use reduces sleep time in kids
(via sciencedaily.com) Original source While screen time is generally known to affect sleep, new research suggests that interactive engagement, such as texting friends or playing video games, delays and reduces the time spent asleep to a greater extent than passive screen time, like watching television -- especially for teens.
