Published Long-distance weaponry identified at the 31,000-year-old archaeological site of Maisières-Canal
(via sciencedaily.com) Original source The hunter-gatherers who settled on the banks of the Haine, a river in southern Belgium, 31,000 years ago were already using spearthrowers to hunt their game. The material found at the archaeological site of Maisières-Canal permits establishing the use of this hunting technique 10,000 years earlier than the oldest currently known preserved spearthrowers. This discovery is prompting archaeologists to reconsider the age of this important technological innovation.
Published Optical-fiber based single-photon light source at room temperature for next-generation quantum processing
(via sciencedaily.com) Original source Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely low temperatures. Now, researchers have developed an ytterbium-doped optical fiber at room temperature. By avoiding the need for expensive cooling solutions, the proposed method offers a cost-effective platform for photonic quantum applications.
Published Cold War spy satellite imagery reveals Ancient Roman forts
(via sciencedaily.com) Original source A new study analyzing declassified Cold War satellite imagery reveals 396 previously undocumented Roman forts and reports that these forts were constructed from east to west, spanning from what is now western Syria to northwestern Iraq. The analysis refutes Father Antoine Poidebard's claim that the forts were located along a north-south axis.
Published Clinical trials could yield better data with fewer patients thanks to new tool
(via sciencedaily.com) Original source Mathematicians have invented a new statistical tool to analyze multiple outcomes from clinical trials, replacing the 60-year-old standard tool that could only look at binary outcomes (survived/ did not survive). This will allow researchers to ask more complex research questions with trials that involve fewer patients, thereby streamlining the process of getting effective treatments to patients.
Published In Prehispanic Cancun, immigrants were treated just like Maya locals
(via sciencedaily.com) Original source Ancient people immigrated to Cancun Island and were treated just like locals, according to a new study.
Published Climate change likely impacted human populations in the Neolithic and Bronze Age
(via sciencedaily.com) Original source Human populations in Neolithic Europe fluctuated with changing climates, according to a new study.
Published Origin of ancient mummified baboons found in Egypt
(via sciencedaily.com) Original source Primatologists are using genetic analysis to determine the geographic origin of ancient mummified baboons found in Egypt. The team finds evidence that the two legendary trading regions of Punt and Adulis may have been the same place separated by a thousand years of history.
Published Ancient sea monster remains reveal oldest mega-predatory pliosaur
(via sciencedaily.com) Original source The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.
Published To excel at engineering design, generative AI must learn to innovate, study finds
(via sciencedaily.com) Original source A new study reveals the pitfalls of deep generative models when they are tasked with solving engineering design problems. The researchers say if mechanical engineers want help from AI for novel ideas and designs, they'll have to refocus those models beyond 'statistical similarity.'
Published Researchers identify the oldest pieces of Baltic amber found on the Iberian Peninsula: imports began over 5,000 years ago
(via sciencedaily.com) Original source Baltic amber is a luxury material used in jewellery and handicrafts all over the world. Researchers have shown that Baltic amber arrived on the Iberian Peninsula at least in the 4th millennium BC, more than a millennium earlier than previously thought.
Published Study reveals our European ancestors ate seaweed and freshwater plants
(via sciencedaily.com) Original source Researchers say they have found 'definitive' archaeological evidence that seaweeds and other local freshwater plants were eaten in the mesolithic, through the Neolithic transition to farming and into the Early Middle Ages, suggesting that these resources, now rarely eaten in Europe, only became marginal much more recently.
Published Scientists investigate Grand Canyon's ancient past to predict future climate impacts
(via sciencedaily.com) Original source A team explores relationship between warming post-Ice Age temperatures and intensifying summer monsoon rains on groundwater reserves.
Published Pollen analysis suggests peopling of Siberia and Europe by modern humans occurred during a major Pleistocene warming spell
(via sciencedaily.com) Original source A new study appearing in Science Advances compares Pleistocene vegetation communities around Lake Baikal in Siberia, Russia, to the oldest archeological traces of Homo sapiens in the region. The researchers use the 'remarkable evidence' to tell a compelling story from 45,000-50,000 years ago with new detail: how the first humans migrated across Europe and Asia.
Published Probing the deep genetic structure of Africa
(via sciencedaily.com) Original source Using ancestry decomposition techniques an international research team has revealed a deeply divergent ancestry among admixed populations from the Angolan Namib desert. This unique genetic heritage brings the researchers closer to understanding the distribution of genetic variation in the broader region of southern Africa before the spread of food production.
Published New study reveals a long history of violence in ancient hunter-gatherer societies
(via sciencedaily.com) Original source Violence was a consistent part of life among ancient communities of hunter-gatherers, according to a new study that looked for signs of trauma on 10,000-year-old skeletal remains from burial sites in northern Chile.
Published Ritual use of human remains dating from the Neolithic
(via sciencedaily.com) Original source An international study has documented post-mortem bone modifications not linked to consumption.
Published Ancient Amazonians intentionally created fertile 'dark earth'
(via sciencedaily.com) Original source A new study suggests patches of fertile soil in the Amazon, known as dark earth, were intentionally produced by ancient Amazonians as a way to improve the soil and sustain large and complex societies.
Published Archaeologists discover world's oldest wooden structure
(via sciencedaily.com) Original source Half a million years ago, earlier than was previously thought possible, humans were building structures made of wood, according to new research.
Published Buried ancient Roman glass formed substance with modern applications
(via sciencedaily.com) Original source Researchers discover how molecules in ancient glass rearrange and recombine with minerals over centuries to form a patina of photonic crystals -- ordered arrangements of atoms that filter and reflect light in very specific ways -- an analog of materials used in communications, lasers and solar cells.
Published How just one set of animal tracks can provide a wealth of information
(via sciencedaily.com) Original source Rock faces in Namibia are decorated with hundreds of stone-age images not only of animals and human footprints, but also of animal tracks. These have been largely neglected to date as researchers lacked the knowledge required to interpret them. Archaeologists have now worked together with animal tracking experts to investigate the engraved animal tracks on six rock faces in more detail, and were able to determine detailed information on the species, age, sex, limbs, side of the body, trackway and relative direction of the tracks.
