Published Chalk-based coating creates a cooling fabric
(via sciencedaily.com) Original source In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.
Published Pilot study uses recycled glass to grow plants for salsa ingredients
(via sciencedaily.com) Original source Tortilla chips and fresh salsa are tasty, but they could be even more appealing if you grow the ingredients yourself. Now, researchers report that some salsa ingredients -- cilantro, bell pepper and jalapeno -- can be more sustainably cultivated with recycled glass. Their pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.
Published Research shows reducing future global flooding hinges on cutting greenhouse gas emissions
(via sciencedaily.com) Original source Pioneering research forecasts worldwide flooding is likely to be significantly worse in future decades if countries fail to meet official pledges to cut carbon emissions.
Published Eco-friendly cooling device with record-breaking efficiency
(via sciencedaily.com) Original source Researchers have developed an eco-friendly refrigeration device with record-breaking cooling performance in the world, setting to transform industries reliant on cooling and reduce global energy use. With a boost in efficiency of over 48%, the new elastocaloric cooling technology opens a promising avenue for accelerating the commercialization of this disruptive technology and addressing the environmental challenges associated with traditional cooling systems.
Published New theory could improve the design and operation of wind farms
(via sciencedaily.com) Original source A new model accurately represents the airflow around rotors, even under extreme conditions. The first comprehensive model of rotor aerodynamics could improve the way turbine blades and wind farms are designed and how wind turbines are controlled.
Published Beetle that pushes dung with the help of 100 billion stars unlocks the key to better navigation systems in drones and satellites
(via sciencedaily.com) Original source An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites.
Published The power of face time: Insights from zebra finch courtship
(via sciencedaily.com) Original source A new study on songbirds sheds light on the power of social interaction to facilitate learning, insights that potentially apply to human development. Researchers discovered that zebra finches deprived of early social experiences could still form strong bonds with a partner later in life. Once placed into cohabitation with a male, females that had never heard a mating song before could quickly develop a preference for his melody.
Published Occupational exposure to particles may increase the risk of chronic kidney disease
(via sciencedaily.com) Original source Exposure to dust and particles at work may increase the risk of chronic kidney disease, a new study shows. Among Swedish construction workers, followed since the 1970s, the risk was 15% higher among exposed.
Published AI approach to drought zoning
(via sciencedaily.com) Original source A recent study shows that climate change may cause many areas in Canada to experience significant droughts by the end of the century. In response, the researchers have introduced an advanced AI-based method to map drought-prone regions.
Published Sharing risk to avoid power outages in an era of extreme weather
(via sciencedaily.com) Original source Heat waves, droughts, and fires place growing stress on the West's electric grid. New research suggests that more integrated management of electricity resources across the region could significantly reduce the risk of power outages and accelerate the transition to clean energy.
Published Renewable energy policies provide benefits across state lines
(via sciencedaily.com) Original source New research suggests U.S. states with clean energy policies provide benefits to their neighbors, including states without their own renewable energy policies.
Published Humpbacks are among animals who manufacture and wield tools
(via sciencedaily.com) Original source Researchers suggest a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create "bubble-nets" to hunt, but they have learned that the animals don't just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds.
Published Environmental laws failing to slow deforestation
(via sciencedaily.com) Original source Australia's environmental laws are failing to stop high rates of tree clearing to make way for agriculture, development and mining.
Published Incorporating humidity improves estimations of climate impacts on health
(via sciencedaily.com) Original source Governments, medical institutions and other bodies require accurate models on health-related matters in order to better organize their activities. Climate change has measurable impacts on society, including on human mortality. However, current models to assess the health impacts of climate change do not account for every environmental parameter, especially humidity, which could influence heat stress perceived by the human body, leaving room for improvement. Researchers have now incorporated humidity data from hundreds of cities into so-called heat stress indicators (HSIs) and assessed their performances in predicting heat-related deaths.
Published 'Masters of shape-shifting': How darkling beetles conquered the world
(via sciencedaily.com) Original source Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.
Published Demand for low-quality credits undermines the voluntary carbon market, study finds
(via sciencedaily.com) Original source Researchers have shown that the 20 companies retiring the most offsets from the voluntary carbon market -- or VCM -- over the past four years have largely relied on low-quality, low-cost credits. These include major oil companies, airlines and aircraft makers, automotive manufacturers, logistics operators, and others.
Published Deadly sea snail toxin could be key to making better medicines
(via sciencedaily.com) Original source Scientists are finding clues for how to treat diabetes and hormone disorders in an unexpected place: a toxin from one of the most venomous animals on the planet.
Published Adaptive 3D printing system to pick and place bugs and other organisms
(via sciencedaily.com) Original source A new adaptive 3D printing system can identify the positions of randomly distributed organisms and safely move them to specific locations for assembly.
Published Researchers uncover the secrets of 'plant puberty'
(via sciencedaily.com) Original source Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.
Published Action plan to help patients with lung disease cope with wildfire smoke
(via sciencedaily.com) Original source A multidisciplinary team has developed an action plan to help patients with respiratory diseases mitigate the consequences of poor air quality from wildfires.
