Published Intelligent soft robotic clothing for automatic thermal adaptation in extreme heat
(via sciencedaily.com) Original source As global warming intensifies, people increasingly suffer from extreme heat. For those working in a high-temperature environment indoors or outdoors, keeping thermally comfortable becomes particularly crucial. A team has now developed thermally-insulated and breathable soft robotic clothing that can automatically adapt to changing ambient temperatures, thereby helping to ensure worker safety in hot environments.
Published Warming waters and nutrient overload: A dangerous combination threatening our rivers and lakes
(via sciencedaily.com) Original source New international research found that food webs are becoming less complex in warmer, nutrient-rich waters.
Published Tropical Atlantic mixing rewrites climate pattern rules
(via sciencedaily.com) Original source Changes in the Atlantic Ocean's mixed layer are the primary force behind the Atlantic Multidecadal Variability (AMV).
Published Climate change raised the odds of unprecedented wildfires in 2023-24
(via sciencedaily.com) Original source Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
Published Changing food consumers' choices may help cut greenhouse gases
(via sciencedaily.com) Original source Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets.
Published Delivery robots' green credentials make them more attractive to consumers
(via sciencedaily.com) Original source The smaller carbon footprint, or wheel print, of automatic delivery robots can encourage consumers to use them when ordering food, according to a new study. The suitcase-sized, self-driving electric vehicles are much greener than many traditional food delivery methods because they have low, or even zero, carbon emissions. In this study, participants who had more environmental awareness and knowledge about carbon emissions were more likely to choose the robots as a delivery method. The green influence went away though when people perceived the robots as a high-risk choice -- meaning they worried that their food would be late, cold or otherwise spoiled before it arrived.
Published Expansion of agricultural land threatens climate and biodiversity
(via sciencedaily.com) Original source Food, feed, fiber, and bioenergy: The demand for agricultural raw materials is rising. How can additional cultivation areas be reconciled with nature conservation? Researchers have developed a land-use model that provides answers.
Published The mother of all motion sensors
(via sciencedaily.com) Original source Researchers have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.
Published Ships now spew less sulfur, but warming has sped up
(via sciencedaily.com) Original source New findings document fewer ship tracks, reduced cloud cover, and boosted warming after ship emissions regulations took effect in 2020.
Published New method for orchestrating successful collaboration among robots
(via sciencedaily.com) Original source New research shows that programming robots to create their own teams and voluntarily wait for their teammates results in faster task completion, with the potential to improve manufacturing, agriculture and warehouse automation.
Published Engineers make tunable, shape-changing metamaterial inspired by vintage toys
(via sciencedaily.com) Original source Common push puppet toys in the shapes of animals and popular figures can move or collapse with the push of a button at the bottom of the toys' base. Now, a team of engineers has created a new class of tunable dynamic material that mimics the inner workings of push puppets, with applications for soft robotics, reconfigurable architectures and space engineering.
Published New study unveils 16,000 years of climate history in the tropical Andes
(via sciencedaily.com) Original source Researchers highlight the roles of carbon dioxide and ocean currents as key drivers of temperature fluctuations in the tropical Andes over a 16,000 year period.
Published Balancing technology and governance are key to achieving climate goals
(via sciencedaily.com) Original source Despite advancements in clean energy, global CO2 emissions continue to rise. IIASA researchers contributed to a new international study that underscores the importance of integrating technological advancements with robust institutional capacities to formulate effective climate policies.
Published Just say 'climate change' -- not 'climate emergency'
(via sciencedaily.com) Original source The familiar terms 'climate change' and 'global warming' are more likely to resonate with people than other commonly used phrases.
Published Long-distance relationship revealed in the seemingly random behavior of bowhead whales
(via sciencedaily.com) Original source Applying chaos theory to the movement of iconic arctic whales uncovered a 24-hour diving cycle and a long-range (~100 km) synchronization.
Published Researchers find unexpectedly large methane source in overlooked landscape
(via sciencedaily.com) Original source Researchers reported that upland landscapes were releasing some of the highest methane emissions yet documented among northern terrestrial ecosystems. The research was sparked when a potent greenhouse gas began ballooning under lawns in Fairbanks.
Published Greenland mega-tsunami led to week-long oscillating fjord wave
(via sciencedaily.com) Original source In September 2023, a megatsunami in remote eastern Greenland sent seismic waves around the world, piquing the interest of the global research community. The event created a week-long oscillating wave in Dickson Fjord, according to a new report in The Seismic Record.
Published Record-breaking recovery of rocks that originated in Earth's mantle could reveal secrets of planet's history
(via sciencedaily.com) Original source Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.
Published Artificial compound eye to revolutionize robotic vision at lower cost but higher sensitivity
(via sciencedaily.com) Original source A research team has recently developed a novel artificial compound eye system that is not only more cost-effective, but demonstrates a sensitivity at least twice that of existing market products in small areas. The system promises to revolutionize robotic vision, enhance robots' abilities in navigation, perception and decision-making, while promoting commercial application and further development in human-robot collaboration.
Published Detecting climate change using aerosols
(via sciencedaily.com) Original source Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.
