Published Unlocking the secrets of the ancient coastal Maya
(via sciencedaily.com) After more than a decade of research, scientists share what they have learned about the people who lived on a stretch of coastline in Quintana Roo Mexico over a span of 3,000 years.
Published Solar-powered chemistry uses carbon dioxide and water to make feedstock for fuels, chemicals
(via sciencedaily.com) Solar-powered synthesis gas could recycle carbon dioxide into fuels and useful chemicals, an international team of researchers has shown.
Published Caught in the act: Key chemical intermediates in pollutant-to-fuel reaction identified
(via sciencedaily.com) Researchers identified chemical intermediates in the hydrogenation of copper-adsorbed formate. Depending on the temperature, some of the hydrogenation product decomposed into formaldehyde. The activation energy was also quantified, based on experimental and computational work. These results will be useful for optimizing production of methanol fuel from carbon dioxide.
Published Study points to Armenian origins of ancient crop with aviation biofuel potential
(via sciencedaily.com) Camelina, an oilseed plant grown in modern-day Ukraine, may have been a more important and widespread crop than previously thought. New findings could inform breeding programs to improve this crop for biofuels applications.
Published Underwater jars reveal Roman period winemaking practices
(via sciencedaily.com) Winemaking practices in coastal Italy during the Roman period involved using native grapes for making wine in jars waterproofed with imported tar pitch, according to a new study.
Published Ice Age wolf DNA reveals dogs trace ancestry to two separate wolf populations
(via sciencedaily.com) An international group of geneticists and archaeologists have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, one of the biggest unanswered questions about human prehistory.
Published The heat is on: Traces of fire uncovered dating back at least 800,000 years
(via sciencedaily.com) Original source Scientists reveal an advanced, innovative method that they have developed and used to detect nonvisual traces of fire dating back at least 800,000 years -- one of the earliest known pieces of evidence for the use of fire. The newly developed technique may provide a push toward a more scientific, data-driven type of archaeology, but -- perhaps more importantly -- it could help us better understand the origins of the human story, our most basic traditions and our experimental and innovative nature.
Published Offshore wind farms expected to reduce clam fishery revenue, study finds
(via sciencedaily.com) An important East Coast shellfish industry is projected to suffer revenue losses as offshore wind energy develops along the U.S. Northeast and Mid-Atlantic coasts, according to two recent studies.
Published Indigenous communities used the Caribbean Sea as an aquatic highway
(via sciencedaily.com) Researchers recently turned to pottery to tease apart the navigational history of the Caribbean, analyzing the composition of 96 fired clay fragments across 11 islands. The study was conducted in the Greater Antilles and marks the first time that pottery artifacts from the Lucayan Islands -- The Bahamas plus the Turks and Caicos Islands -- have been analyzed to determine their elemental composition and origin.
Published Modern wind turbines can more than compensate for decline in global wind resource
(via sciencedaily.com) Wind energy contributes significantly to the energy sector's sustainable, low-CO2 transformation. However, the efficiency of wind turbines depends on available wind resources and the technical characteristics of the turbines.
Published 1,700-year-old Korean genomes show genetic heterogeneity in Three Kingdoms period Gaya
(via sciencedaily.com) Scientists have successfully sequenced and studied the whole genome of eight 1,700-year-old individuals dated to the Three Kingdoms period of Korea (approx. 57 BC-668 AD). The first published genomes from this period in Korea and bring key information for the understanding of Korean population history.
Published More digging needed to see whether bones of fallen Waterloo soldiers were sold as fertilizer, as few human remains have ever been found
(via sciencedaily.com) Launched on the anniversary of the conflict, a new study suggests that mystery still surrounds what happened to the bodies of Waterloo militaries.
Published Olive trees were first domesticated 7,000 years ago, study finds
(via sciencedaily.com) A new study has unraveled the earliest evidence for domestication of a fruit tree, researchers report. The researchers analyzed remnants of charcoal from the Chalcolithic site of Tel Zaf in the Jordan Valley and determined that they came from olive trees. Since the olive did not grow naturally in the Jordan Valley, this means that the inhabitants planted the tree intentionally about 7,000 years ago.
Published Unique Viking shipyard discovered at Birka
(via sciencedaily.com) Archaeologists have located a unique Viking Age shipyard site at Birka on Björkö in Lake Mälaren. The discovery challenges previous theories about how the maritime activities of the Viking Age were organized.
Published Inspired by palm trees, scientists develop hurricane-resilient wind turbines
(via sciencedaily.com) New results from real-world tests of a downwind turbine could inform and improve the wind energy industry in a world with intensifying hurricanes and a greater demand for renewable energy.
Published Origins of the Black Death identified
(via sciencedaily.com) The Black Death, the biggest pandemic of our history, was caused by the bacterium Yersinia pestis and lasted in Europe between the years 1346 and 1353. Despite the pandemic's immense demographic and societal impacts, its origins have long been elusive. Now, scientists have obtained and studied ancient Y. pestis genomes that trace the pandemic's origins to Central Asia.
Published Wreck of historic royal ship discovered off the English coast
(via sciencedaily.com) A royal shipwreck has been discovered off the English coast. The wreck is of one of the most famous ships of the 17th century -- The Gloucester -- which sank 340 years ago while carrying the future King of England, James Stuart. Since running aground on a sandbank on May 6, 1682, the wreck has lain half-buried on the seabed, its exact whereabouts unknown. It has now been found.
Published Bioarchaeological evidence of very early Islamic burials in the Levant
(via sciencedaily.com) A new study combining archaeological, historical and bioarchaeological data provides new insights into the early Islamic period in modern-day Syria. The research team was planning to focus on a much older time period but came across what they believe to be remains of early Muslims in the Syrian countryside.
Published Pre-historic Wallacea: A melting pot of human genetic ancestries
(via sciencedaily.com) The Wallacean islands of present-day Eastern Indonesia have a long history of occupation by modern humans. Notably, the maritime expansion of Austronesian speakers into Wallacea left archaeological traces of a Neolithic lifestyle and a genetic imprint still detectable in Eastern Indonesians today. To gain further insights into Wallacea's settlement history, scientists sequenced and analyzed sixteen ancient genomes from different islands of Wallacea, finding evidence for repeated genetic admixtures starting at least 3,000 years ago.
Published Death of bats at wind turbines interrupts natural food chains
(via sciencedaily.com) The numerous casualties of bats at wind turbines (WT) have a negative impact on the populations of affected species and potentially far-reaching consequences for the biodiversity in rural areas. Until now, it could only be assumed that the death of bats had further consequences. Now, a team of scientists show that natural food chains are interrupted, which can have far-reaching negative consequences for agriculture and forestry. The study demonstrates the extent to which the functional importance of bats for habitats has been underestimated so far.
