Published Early-stage subduction invasion
(via sciencedaily.com) Original source Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in what is known as the Wilson cycle.
Published Anthropologists' research unveils early stone plaza in the Andes
(via sciencedaily.com) Original source Located at the Callacpuma archaeological site in the Cajamarca Basin of northern Peru, the plaza is built with large, vertically placed megalithic stones -- a construction method previously unseen in the Andes.
Published Some Pre-Roman humans were buried with dogs, horses and other animals
(via sciencedaily.com) Original source Some people from an ancient community in what is now northern Italy were interred with animals and animal parts from species such as dogs, horses and pigs. The reasons remain mysterious, but might indicate an enduring companion relationship between these humans and animals, or religious sacrificial practices, according to a new study.
Published Archaeologists discover oldest known bead in the Americas
(via sciencedaily.com) Original source The bead found at the La Prele Mammoth site in Wyoming's Converse County is about 12,940 years old and made of bone from a hare.
Published Scandinavia's first farmers slaughtered the hunter-gatherer population, study finds
(via sciencedaily.com) Original source Following the arrival of the first farmers in Scandinavia 5,900 years ago, the hunter-gatherer population was wiped out within a few generations, according to a new study. The results, which are contrary to prevailing opinion, are based on DNA analysis of skeletons and teeth found in what is now Denmark.
Published Ancient rocks improve understanding of tectonic activity between earthquakes
(via sciencedaily.com) Original source Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.
Published New method to more accurately spot underground nuclear tests
(via sciencedaily.com) Original source A more accurate way of identifying underground nuclear tests, including those conducted in secret, has been developed.
Published Thailand's Iron Age Log Coffin culture
(via sciencedaily.com) Original source A mortuary practice known as Log Coffin culture characterizes the Iron Age of highland Pang Mapha in northwestern Thailand. Between 2,300 and 1,000 years ago, individuals were buried in large wooden coffins on stilts, mostly found in caves and rock shelters.
Published A new origin story for deadly Seattle fault
(via sciencedaily.com) Original source The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there. A new origin story, proposed in a new study, could explain the fault system's earliest history and help scientists improve hazard modeling for the densely populated region.
Published Prehistoric mobility among Tibetan farmers, herders shaped highland settlement patterns, cultural interaction, study finds
(via sciencedaily.com) Original source Using advanced geospatial modeling to compare environmental and archaeological evidence, researchers found evidence that connects ancient mobility and subsistence strategies to cultural connections forged among Tibetan farmers and herders in the Bronze and Iron Ages -- adding to understanding of how and why ancient communities built social relationships and cultural identities across the extreme terrain in Tibet.
Published Did dementia exist in ancient Greek and Rome?
(via sciencedaily.com) Original source Did the ancient Greeks and Romans experience Alzheimer's? Medical texts from 2,500 years ago rarely mention severe memory loss, suggesting today's widespread dementia stems from modern environments and lifestyles, a new analysis shows.
Published Archaeological evidence of seasonal vitamin D deficiency discovered
(via sciencedaily.com) Original source Rickets ran rife in children following the Industrial Revolution, but new research has found factory work and polluted cities aren't entirely to blame for the period's vitamin D deficiencies.
Published Neanderthals and humans lived side by side in Northern Europe 45,000 years ago
(via sciencedaily.com) Original source Archaeologists have debated whether Neanderthals or modern humans made stone tools that are found at sites across northern Europe and date from about 40,000 years ago. A new excavation at one site in Germany turned up 45,000-year-old bone fragments that, when analyzed for mitochondrial DNA, proved to be from Homo sapiens. This is the earliest evidence that modern humans overlapped with Neanderthals in northwest Europe, thousands of years before Neanderthals went extinct.
Published How did humans learn to walk? New evolutionary study offers an earful
(via sciencedaily.com) Original source A new study, which centers on evidence from skulls of a 6-million-year-old fossil ape, Lufengpithecus, offers important clues about the origins of bipedal locomotion courtesy of a novel method: analyzing its bony inner ear region using three-dimensional CT-scanning. The inner ear appears to provide a unique record of the evolutionary history of ape locomotion.
Published New research challenges hunter-gatherer narrative
(via sciencedaily.com) Original source Analysis of the remains of 24 individuals from the Wilamaya Patjxa and Soro Mik'aya Patjxa burial sites in Peru shows that early human diets in the Andes Mountains were composed of 80 percent plant matter and 20 percent meat.
Published DNA from preserved feces reveals ancient Japanese gut environment
(via sciencedaily.com) Original source DNA from ancient feces can offer archaeologists new clues about the life and health of Japanese people who lived thousands of years ago, according to a new study.
Published Ancient brown bear genomes sheds light on Ice Age losses and survival
(via sciencedaily.com) Original source The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyena), the brown bear is one of the lucky survivors that made it through to the present. The question has puzzled biologists for close to a century -- how was this so?
Published Key factors in human-made earthquakes
(via sciencedaily.com) Original source Researchers report that the roughness of pre-existing faults and associated stress heterogeneity in geological reservoirs play a key role for causing human-made earthquakes, so-called runaway events. The study combines novel fluid injection experiments under acoustic monitoring performed in GFZ's geomechanical laboratory with numerical modelling results.
Published Despite intensive scientific analyses, this centaur head remains a mystery
(via sciencedaily.com) Original source For almost 200 years, archaeologists have been puzzled by a mysterious brown stain on the ancient Greek Parthenon temple in Greece. Now, researchers have conducted new scientific analyses, and their verdict is clear: The mystery remains.
Published Stalagmites as climate archive
(via sciencedaily.com) Original source When combined with data from tree-ring records, stalagmites can open up a unique archive to study natural climate fluctuations, a research team has demonstrated. The researchers analyzed the isotopic composition of oxygen in a stalagmite formed from calcareous water in a cave in southern Germany. In conjunction with the data acquired from tree rings, they were able to reconstruct short-term climate fluctuations over centuries and correlate them with historically documented environmental events.
