Published New insights into the degradation dynamics of organic material in the seafloor
(via sciencedaily.com) Original source Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.
Published Alaska's rusting waters: Pristine rivers and streams turning orange
(via sciencedaily.com) Original source Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.
Published Legacy of Indigenous stewardship of camas dates back more than 3,500 years
(via sciencedaily.com) Original source A new study found evidence that Indigenous groups in the Pacific Northwest were intentionally harvesting edible camas bulbs at optimal stages of the plant's maturation as far back as 3,500 years ago.
Published What pottery reveals about prehistoric Central European culinary traditions
(via sciencedaily.com) Original source The analysis of fat traces in over one hundred pottery vessels reveals deep changes in food consumption and preparation by communities living in central Germany between the Early Neolithic and the Late Bronze Age, as well as in their relation with innovations in pottery styles and decorations. In a groundbreaking study, researchers identified a generalized inclusion of dairy products in prehistoric diets, a preference in consuming pork with the arrival of communities from the Eurasian Steppe, and the importance of dairy products in funeral rites. Central Germany was a key region for the emergence of great prehistoric cultures, such as the Linear Pottery Culture, the Corded Ware Culture, the Bell Beaker populations and the Unetice Culture, one of the first state societies in Europe.
Published Researchers find unique adaptations of fungus associated with bee bread
(via sciencedaily.com) Original source The past attempts of honey bee researchers to inventory the fungal diversity in honey bee colonies revealed that Aspergillus flavus is frequently found in hives. In a new study, researchers have discovered that this fungus is uniquely adapted to survive in bee colonies.
Published Can coal mines be tapped for rare earth elements?
(via sciencedaily.com) Original source A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.
Published Evolutionary history of extinct duck revealed
(via sciencedaily.com) Original source The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.
Published Unraveling the drought dilemma: Can reservoirs be a carbon source?
(via sciencedaily.com) Original source A team delves into the spatiotemporal patterns of water volume and total organic carbon concentration of agricultural reservoirs.
Published Extreme complexity in formation of rare earth mineral vital for tech industry
(via sciencedaily.com) Original source Researchers have unveiled that myriad, intricate factors influence the genesis and chemistry of bastnasite and rare earth carbonates, which are critically needed for today's tech industry and its hardware outputs. Their work unveils a newly acquired depth of understanding that had previously been unexplored in this field. In combination, the findings mark a significant advancement and promise to reshape our understanding of rare earth mineral formation.
Published Scientists develop new geochemical 'fingerprint' to trace contaminants in fertilizer
(via sciencedaily.com) Original source An international team of scientists has revealed high levels of toxic metals in global phosphate fertilizers using a isotopic variants of the element strontium as a tracer to uncover metals in soil, groundwater and possibly the food chain.
Published Can we revolutionize the chemical industry and create a circular economy? Yes, with the help of catalysts
(via sciencedaily.com) Original source A new commentary paper puts forth a transformative solution to the unsustainable reliance on fossil resources by the chemical industry: catalysis to leverage sustainable waste resources, ushering the industry from a linear to a circular economy.
Published Zombie cells in the sea: Viruses keep the most common marine bacteria in check
(via sciencedaily.com) Original source Marine microbes control the flux of matter and energy essential for life in the oceans. Among them, the bacterial group SAR11 accounts for about a third of all the bacteria found in surface ocean waters. A study now reveals that at times nearly 20% of SAR11 cells are infected by viruses, significantly reducing total cell numbers. The viruses can also transform these once thriving bacteria into zombies, a phenomenon observed for the first time and widespread in the oceans.
Published Early arrival and expansion of palaeolithic people on Cyprus
(via sciencedaily.com) Original source The patterns of dispersal of early humans across continents and islands are hotly debated, but researchers have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought. In examining the timing of the first human occupation of Cyprus, research found that large islands in the Mediterranean Sea were attractive and favorable destinations for palaeolithic peoples. These findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies.
Published Study reveals consumers value animal welfare more than environmental sustainability when buying meat and dairy products
(via sciencedaily.com) Original source The treatment of animals rates higher than green issues when consumers choose meat and dairy products. That's according to a new study, which suggests that while consumers consider sustainability important, other factors such as taste, quality, and animal welfare take precedence in their purchasing decisions.
Published Wind farms can offset their emissions within two years
(via sciencedaily.com) Original source After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants.
Published From roots to resilience: investigating the vital role of microbes in coastal plant health
(via sciencedaily.com) Original source Understanding how salt marsh grass stays healthy is of crucial ecological importance, and studying the ways bacteria interact with these plants is key. Thanks to recent advances in genomic technology, biologists have begun to reveal never-before-seen ecological processes.
Published Carbon-capture batteries developed to store renewable energy, help climate
(via sciencedaily.com) Original source Researchers are developing battery technologies to fight climate change in two ways, by expanding the use of renewable energy and capturing airborne carbon dioxide. Researchers recently created and tested two different formulations for batteries that store renewable energy; when the energy is later used, an electrochemical reaction converts industrial carbon dioxide emissions into a solid form that has the potential to be used in other products.
Published Making batteries takes a lot of lithium: Some could come from gas well wastewater
(via sciencedaily.com) Original source A new analysis suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.
Published Scientists want to know how the smells of nature benefit our health
(via sciencedaily.com) Original source Spending time in nature is good for us. And knowing more about nature's effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Many studies have focused on how seeing nature affects us. A team of scientists from around the world wants to understand what the nose knows. They are calling for more research into how odors and scents from natural settings impact our health and well-being.
