Published Mapping the middle ground: Balancing mining activities with survival of Utah's rare plants
(via sciencedaily.com) Original source A research team is mapping out new modeling strategies so that proposed energy development and the management of rare plants don't necessarily have to be mutually exclusive endeavors.
Published Drought encouraged Attila's Huns to attack the Roman empire, tree rings suggest
(via sciencedaily.com) Hunnic peoples migrated westward across Eurasia, switched between farming and herding, and became violent raiders in response to severe drought in the Danube frontier provinces of the Roman empire, a new study argues.
Published Early humans may have first walked upright in the trees
(via sciencedaily.com) Human bipedalism -- walking upright on two legs -- may have evolved in trees, and not on the ground as previously thought, according to a new study.
Published Study examines feeding damage caused by spotted lanternflies on young maples
(via sciencedaily.com) Original source Short-term, heavy feeding by adult spotted lanternflies on young maple trees inhibits photosynthesis, potentially impairing the tree's growth by up to 50 percent, according to a new study.
Published Extinct 'monkey lemur' shows similarities to fossil humans
(via sciencedaily.com) Analysis of teeth of extinct lemurs has revealed fascinating clues to the evolution of humans, a new study has found.
Published Immune system of modern Papuans shaped by DNA from ancient Denisovans, study finds
(via sciencedaily.com) Modern Papuans' immune system likely evolved with a little help from the Denisovans, a mysterious human ancestor who interbred with ancient humans, according to a new study.
Published How intensive agriculture turned a wild plant into a pervasive weed
(via sciencedaily.com) Agriculture is driving rapid evolutionary change, not just on farms but also in wild species in surrounding landscapes, new research has found.
Published For 400 years, Indigenous tribes buffered climate's impact on wildfires in the American Southwest
(via sciencedaily.com) Original source Devastating megafires are becoming more common, in part, because the planet is warming. But a new study suggests bringing 'good fire' back to the U.S. and other wildfire fire-prone areas, as Native Americans once did, could potentially blunt the role of climate in triggering today's wildfires.
Published Jawbone may represent earliest presence of humans in Europe
(via sciencedaily.com) For over a century, one of the earliest human fossils ever discovered in Spain has been long considered a Neanderthal. However, new analysis from an international research team dismantles this century-long interpretation, demonstrating that this fossil is not a Neanderthal; rather, it may actually represent the earliest presence of Homo sapiens ever documented in Europe.
Published Ancient DNA from medieval Germany tells the origin story of Ashkenazi Jews
(via sciencedaily.com) Extracting ancient DNA from teeth, an international group of scientists peered into the lives of a once-thriving medieval Ashkenazi Jewish community in Erfurt, Germany. The findings show that the Erfurt Jewish community was more genetically diverse than modern day Ashkenazi Jews.
Published Interdisciplinary environmental history: How narratives of the past can meet the challenges of the anthropocene
(via sciencedaily.com) A new article discusses vital methodological issues for humanities-based historical inquiry and argues that the challenges of the Anthropocene demand interdisciplinary research informed by a variety of historical narratives.
Published Human evolution wasn't just the sheet music, but how it was played
(via sciencedaily.com) A team of researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.
Published 'Primordial super-enhancers' provide early snapshot of the mechanisms that allowed for multicellularity
(via sciencedaily.com) A new study has found that organelle-like transcriptional condensates are an ancient and flexible tool used by cells to drive rapid gene expression.
Published 1,700-year-old spider monkey remains discovered in Teotihuacán, Mexico
(via sciencedaily.com) Original source The complete skeletal remains of a spider monkey -- seen as an exotic curiosity in pre-Hispanic Mexico -- grants researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers. The remains of other animals were also discovered, as well as thousands of Maya-style mural fragments and over 14,000 ceramic sherds from a grand feast. These pieces are more than 1,700 years old.
Published Oldest evidence of the controlled use of fire to cook food, researchers report
(via sciencedaily.com) Original source The remains of a huge carp fish mark the earliest signs of cooking by prehistoric human to 780,000 years ago, predating the available data by some 600,000 years, according to researchers.
