Published Modern behavior explains prehistoric economies
(via sciencedaily.com) Original source What if the 'Market Economy' always existed? Archaeologists tried to answer this question by researching how much Bronze Age people used to spend to sustain their daily lives. Their results show that, starting at least 3,500 years ago, the spending habits of prehistoric Europeans were not substantially different from what they are today.
Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published Study examines effect of fish oil in older adults' brains
(via sciencedaily.com) Original source A clinical trial suggests that a subset of older adults with a genetic predisposition to Alzheimer's disease may benefit from fish oil supplements.
Published Tipping risks from overshooting 1.5 °C can be minimized if warming is swiftly reversed
(via sciencedaily.com) Original source Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 C of global warming after a period of overshoot. A new study indicates that this risk can be minimized if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers write. They analyzed the tipping risks for four interconnected core climate tipping elements: the Greenland Ice Sheet, the West Antarctic Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), and the Amazon Rainforest.
Published Towards smart cities: Predicting soil liquefaction risk using artificial intelligence
(via sciencedaily.com) Original source Soil liquefaction that results in infrastructure damage has long been a point of contention for urban planners and engineers. Accurately predicting the soil liquefaction risk of a region could help overcome this challenge. Accordingly, researchers applied artificial intelligence to generate soil liquefaction risk maps, superseding already published risk maps.
Published Pursuing the middle path to scientific discovery
(via sciencedaily.com) Original source Scientists have made significant strides in understanding the properties of a ferroelectric material under an electric field. This breakthrough holds potential for advances in computer memory, lasers and sensors for ultraprecise measurements.
Published 'Smarter' semiconductor technology for training 'smarter' artificial intelligence
(via sciencedaily.com) Original source Scientists develop next-generation semiconductor technology for high-efficiency, low-power artificial intelligence.
Published Mass extinction 66 million years ago triggered rapid evolution of bird genomes
(via sciencedaily.com) Original source Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds.
Published The next generation of RNA chips
(via sciencedaily.com) Original source An international research team has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used in biotechnological and medical research. The chemical synthesis of these chips is now twice as fast and seven times more efficient.
Published 3D models provide unprecedented look at corals' response to bleaching events
(via sciencedaily.com) Original source Marine biologists are providing a glimpse into coral 'bleaching' responses to stress, using imaging technology to pinpoint coral survival rates following multiple bleaching events off the island of Maui. Using a time series of coral reef 3D models from Maui, the researchers tracked the bleaching response of 1,832 coral colonies from 2014 to 2021. The seven-year data set provided detailed imagery of the reefs year-by-year, allowing the team to identify patterns of coral growth and survivorship through sequential bleaching events that occurred in 2015 and 2019.
Published Underwater mapping reveals new insights into melting of Antarctica's ice shelves
(via sciencedaily.com) Original source Clues to future sea level rise have been revealed by the first detailed maps of the underside of a floating ice shelf in Antarctica. An international research team deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica.
Published Downwind states face disproportionate burden of air pollution
(via sciencedaily.com) Original source A recent U.S. Supreme Court decision to block a federal rule curbing interstate air pollution further complicates efforts to reduce emissions and adds to an already disproportionate burden on 'downwind' states, according to researchers.
Published Smell reports reveal the need to expand urban air quality monitoring, say researchers
(via sciencedaily.com) Original source Researchers have uncovered surprising insights into the Vancouver region's 'smellscape' using data from the Smell Vancouver app. Analyzing 549 reports from one year of app data, they discovered that 'rotten' and 'chemical' odours dominated, making up about 65 per cent of submissions. These unpleasant smells were linked to self-reported health issues like headaches and anxiety, leading some residents to change their behaviours, like closing windows even in stifling-hot weather.
Published Nasal COVID-19 vaccine halts transmission, animal study finds
(via sciencedaily.com) Original source A nasal COVID-19 vaccine blocks transmission of the virus, according to an animal study. The findings suggest that vaccines delivered directly to the nose or mouth could play a critical role in containing the spread of respiratory infections.
Published Scientists devise method to secure Earth's biodiversity on the moon
(via sciencedaily.com) Original source New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
Published Researchers explore cancer susceptibility in birds
(via sciencedaily.com) Original source In one of the largest studies of cancer susceptibility across bird species, researchers describe an intriguing relationship between reproductive rates and cancer susceptibility.
Published Barriers designed to prevent saltwater intrusion may worsen inland flooding
(via sciencedaily.com) Original source Building protection barriers without accounting for potential inland flooding risks from groundwater can eventually worsen the very issues they aim to solve.
Published Cracking the carb code: Researchers create new glycemic index database to improve dietary awareness
(via sciencedaily.com) Original source Researchers create the first national glycemic index database, revealing how common foods impact health and contribute to chronic diseases.
Published Cash and conservation: A worldwide analysis of wildlife represented on money
(via sciencedaily.com) Original source Researchers investigate the representation of native fauna on 4,541 banknotes from 207 countries between 1980 and 2017, to identify geographic hotspots and taxonomic patterns, and determine whether threatened and endemic species were more readily represented.
Published Climate change means that tropical cyclones in Southeast Asia are developing faster, lasting longer
(via sciencedaily.com) Original source A study reveals that tropical cyclones in Southeast Asia are now forming closer to coastlines, intensifying more rapidly, and lingering longer over land.
