Published Family trees from the European Neolithic
(via sciencedaily.com) Original source The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.
Published Missing island explains how endemic species on the Miyako Islands emerged
(via sciencedaily.com) Original source Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.
Published Picky green sea turtle has travelled to the same place to eat for generations
(via sciencedaily.com) Original source For approximately 3,000 years, generations of green sea turtles have returned to the same seagrass meadows to eat. The fact that this stretches over many generations highlights the importance of protecting seagrass meadows along the coasts of North Africa.
Published Hidden details of Egyptian paintings revealed by chemical imaging
(via sciencedaily.com) Original source Portable chemical imaging technology can reveal hidden details in ancient Egyptian paintings, according to new research.
Published Study examines centuries of identity lost because of slavery
(via sciencedaily.com) Original source Using computational methods informed by genetic data, researchers estimate that a random African American born between 1960 and 1965 is descended from, on average, 314 African and 51 European ancestors reaching back to 1619.
Published Giant stone artefacts found on rare Ice Age site in Kent, UK
(via sciencedaily.com) Original source Researchers have discovered some of the largest early prehistoric stone tools in Britain.
Published Mountains vulnerable to extreme rain from climate change
(via sciencedaily.com) Original source A new study finds that as rising global temperatures shift snow to rain, mountains across the Northern Hemisphere will be hotspots for extreme rainfall events that could trigger floods and landslides -- potentially impacting a quarter of the world's population.
Published Freely available risk model for hurricanes, tropical cyclones
(via sciencedaily.com) Original source As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.
Published Orangutans can make two sounds at the same time, similar to human beatboxing, study finds
(via sciencedaily.com) Original source Orangutans can make two separate sounds simultaneously, much like songbirds or human beatboxers, according to a new study.
Published New research finds that more than 90% of global aquaculture faces substantial risk from environmental change
(via sciencedaily.com) Original source Many of the world's largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark study has shown.
Published Research in a place where geological processes happen before your eyes
(via sciencedaily.com) Original source Taiwan experiences some of the world's fastest rates of mountain building -- they are growing at a faster rate than our fingernails grow in a year. The mountains also see frequent and significant earthquakes, the region experiences about four typhoons per year on average, and in some places, it receives upwards of several meters of rain annually.
Published Don't wait, desalinate: A new approach to water purification
(via sciencedaily.com) Original source A water purification system separates out salt and other unnecessary particles with an electrified version of dialysis. Successfully applied to wastewater with planned expansion into rivers and seas, the method saves money and saps 90% less energy than its counterparts.
Published Act now to prevent uncontrolled rise in carbon footprint of computational science
(via sciencedaily.com) Original source Scientists have set out principles for how computational science -- which powers discoveries from unveiling the mysteries of the universe to developing treatments to fight cancer to improving our understanding of the human genome, but can have a substantial carbon footprint -- can be made more environmentally sustainable.
Published Study of Earth's stratosphere reduces uncertainty in future climate change
(via sciencedaily.com) Original source New research reduces uncertainty in future climate change linked to the stratosphere, with important implications for life on Earth. A significant source of uncertainty relates to future changes to water vapor in the stratosphere, an extremely dry region of the atmosphere 15--50 km above the Earth's surface. Future increases in water vapor here risk amplifying climate change and slowing down the recovery of the ozone layer, which protects life on Earth from harmful solar ultraviolet radiation.
Published Study of deep-sea corals reveals ocean currents have not fuelled rise in atmospheric carbon dioxide
(via sciencedaily.com) Original source Pioneering analysis of deep-sea corals has overturned the idea that ocean currents contributed to increasing global levels of carbon dioxide in the air over the past 11,000 years.
Published Worse than diesel and gasoline? Bioenergy as bad as fossils if there is no pricing of CO2 emissions from land-use change, experts argue
(via sciencedaily.com) Original source Demand for modern biofuels is expected to grow substantially in order to mitigate climate emissions. However, they are far from being a climate neutral alternative to gasoline and diesel. A new study shows that under current land-use regulations, CO2 emission factors for biofuels might even exceed those for fossil diesel combustion due to large-scale land clearing related to growing biomass. Before bioenergy can effectively contribute to achieving carbon neutrality, international agreements need to ensure the effective protection of forests and other natural lands by introducing carbon pricing, the expert team argues.
Published Gray whales off Oregon Coast consume millions of microparticles per day
(via sciencedaily.com) Original source Researchers estimate that gray whales feeding off the Oregon Coast consume up to 21 million microparticles per day, a finding informed in part by feces from the whales.
Published Investing in nature improves equity, boosts economy
(via sciencedaily.com) Original source A new study shows that current trends in environmental degradation will lead to large economic losses in the coming decades, hitting the poorest countries hardest. But there is hope: investing in nature can turn those losses into gains.
Published Human impact on wildlife even in protected areas
(via sciencedaily.com) Original source The largest long-term standardized camera-trap survey to date finds that human activity impacts tropical mammals living in protected areas and sheds light on how different species are affected based on their habitat needs and anthropogenic stressors.
Published New nationwide modeling points to widespread racial disparities in urban heat stress
(via sciencedaily.com) Original source Using a combination of satellite data and modeling to study the temperatures and humidity people might feel in urban areas, researchers have pinpointed who in the U.S. is most vulnerable to heat stress.
