Published Giant dinosaur carcasses might have been important food sources for Jurassic predators
(via sciencedaily.com) Original source Carnivorous dinosaurs might have evolved to take advantage of giant carcasses, according to a new study.
Published Ocean warming is accelerating, and hotspots reveal which areas are absorbing the most heat
(via sciencedaily.com) Original source A new study reveals increasing warming rates in the world's oceans in recent decades and the locations with the greatest heat uptake.
Published Dam removals, restoration project on Klamath River expected to help salmon, researchers conclude
(via sciencedaily.com) Original source The world's largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors. However, it will not fully alleviate challenges faced by the species, a team of researchers conclude.
Published Toward sustainable construction: Preparing liquefied stabilized soil from construction sludge
(via sciencedaily.com) Original source Liquefied stabilized soil (LSS) is made with construction waste and used for filling and backfilling long, confined spaces where traditional compaction is difficult. Using LSS helps speed up construction processes while reducing costs, wastage, and environmental impact. Now, researchers have developed a superior, high-flowability LSS from construction sludge with better mechanical properties and fluidity than conventional LSS, which could make the construction industry more sustainable.
Published A mathematical model for studying methane hydrate distribution in the Nankai Trough
(via sciencedaily.com) Original source Naturally occurring methane hydrate deposits are potential sources of energy. However, their observation in natural environments remains challenging. Researchers have now developed a one-dimensional mathematical flow model to indirectly observe the formation and accumulation of methane hydrates under different lithological and fluid conditions in the Nankai Trough of Japan. Numerical simulations using this model revealed important insights that could help in the extraction of methane hydrates and the prevention of geohazards in the future.
Published Efficient biohybrid batteries
(via sciencedaily.com) Original source Formic acid, which can be produced electrochemically from carbon dioxide, is a promising energy carrier. A research team has now developed a fast-charging hybrid battery system that combines the electrochemical generation of formic acid as an energy carrier with a microbial fuel cell. This novel, fast-charging biohybrid battery system can be used to monitor the toxicity of drinking water, just one of many potential future applications.
Published Humans are disrupting natural 'salt cycle' on a global scale, new study shows
(via sciencedaily.com) Original source A new paper revealed that human activities are making Earth's air, soil and freshwater saltier, which could pose an 'existential threat' if current trends continue. Geologic and hydrologic processes bring salts to Earth's surface over time, but human activities such as mining and land development are rapidly accelerating this natural 'salt cycle.'
Published Researchers observe wolves hunting and killing sea otters and harbor seals on Alaska's Katmai coast
(via sciencedaily.com) Original source Firsthand observations of a wolf hunting and killing a harbor seal and a group of wolves hunting and consuming a sea otter on Alaska's Katmai coast have led scientists to reconsider assumptions about wolf hunting behavior.
Published How common desert shrub efficiently harvests water from the air
(via sciencedaily.com) Original source A team of scientists has revealed the mechanism a desert plant native to the United Arab Emirates uses to capture moisture from the desert air in order to survive.
Published Australasia's hidden pollination crisis could threaten biodiversity and food security
(via sciencedaily.com) Original source Australasia's hidden pollination crisis, mirroring global threats, could pose a significant risk to regional biodiversity and food security, new research has found.
Published Soy expansion in Brazil linked to increase in childhood leukemia deaths
(via sciencedaily.com) Original source Brazil's rapid expansion of soy production has meant an associated rise in pesticide use. Researchers found a statistically significant correlation between soy expansion and acute lymphoblastic leukemia (ALL) deaths in children between 2008 and 2019, representing the first population-wide analysis of the association between indirect exposure to agricultural pesticides and cancer.
Published Study uncovers hundred-year lifespans for three freshwater fish species in the Arizona desert
(via sciencedaily.com) Original source New study finds some of the oldest animals in the world living in a place you wouldn't expect: fishes in the Arizona desert.
Published Amphibians have one more thing to worry about--mercury
(via sciencedaily.com) Original source The first widescale assessment of methylmercury in adult amphibians in the U.S. to date shows that, in amphibians, this toxic compound is common, widespread and, at least for some, can reach very high levels.
Published Gaming strategy helps plan for and prevent attacks on infrastructure
(via sciencedaily.com) Original source As technology continues to advance, the likelihood of malevolent attacks and subsequent failures on society's critical infrastructures increases. Blackouts, water shortages, transport collapses -- these potential threats to cities not only come with a hefty price tag but are likely to cause chaos and affect the health and safety of communities. UBC Okanagan Postdoctoral Research Fellow Dr. Amin Ahmadi Digehsara, along with Assistant Professor Dr. Amir Ardestani-Jaafari, both with the Faculty of Management, recently published a study that will enhance the resilience of vital infrastructures against malevolent attacks.
Published Two bee species become one as researchers solve identity puzzle
(via sciencedaily.com) Original source A new study has found that what were thought to be two different species of native Australian bee are in fact one.
Published Evolutionary chance made this bat a specialist hunter
(via sciencedaily.com) Original source It is generally believed that, for millions of years, bats and the insects they hunt at night have adapted to each other in an evolutionary arms race to become better at finding or avoiding each other. Now, a new study shows that this may not be the case at all.
Published Tracking down environmental toxins
(via sciencedaily.com) Original source PFAS, a family of highly fluorinated substances, represent a danger for humans and the environment. Particularly problematic members of this family, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) appear to cause organ damage and cancer, as well as disrupting the endocrine system. Researchers have now introduced a new method for an economical, easy-to-use fluorescence sensor for sensitive on-site testing for PFAS in water samples.
Published The race of water droplets
(via sciencedaily.com) Original source How fast does a droplet flow along a fiber? It depends on the diameter of the fiber... and also on its substructure! These are the findings of a study conducted by researchers who are interested in microfluidics, especially water harvesting in arid/semi-arid regions of our planet.
Published Protein root discovery seals future of climate-proof plants
(via sciencedaily.com) Original source Researchers have discovered a protein that seals plant roots to regulate the uptake of nutrients and water from the soil, the discovery could help develop climate proof crops that require less water and chemical fertilizers.
Published Researcher finds proof of menopause in wild chimpanzees
(via sciencedaily.com) Original source A team of researchers studying the Ngogo community of wild chimpanzees in western Uganda's Kibale National Park for two decades has published a report showing that females in this population can experience menopause and post-reproductive survival.
