Published Microplastics' shape determines how far they travel in the atmosphere
(via sciencedaily.com) Original source Micron-size microplastic debris can be carried by the jet stream across oceans and continents, and their shape plays a crucial role in how far they travel.
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 Cultural adaptation to climate change
(via sciencedaily.com) Original source Examining how human culture evolves in response to a changing environment may help with creating more effective climate change adaptation efforts. Using farming data from across the U.S., a team of researchers conducted a new study of cultural adaptation to climate change. They found that in many places in the U.S. farmers are already adapting to climate change by selecting crops that grow better in new conditions. Focusing on the process of cultural adaptation can improve research and policy to help adapt to a warming world.
Published Amazon deforestation linked to long distance climate warming
(via sciencedaily.com) Original source Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study. The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances.
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 Offset markets: New approach could help save tropical forests by restoring faith in carbon credits
(via sciencedaily.com) Original source A new approach to valuing the carbon storage potential of natural habitats aims to help restore faith in offset schemes, by enabling investors to directly compare carbon credit pricing across a wide range of projects.
Published Low-income countries could lose 30% of nutrients like protein and omega-3 from seafood due to climate change
(via sciencedaily.com) Original source The nutrients available from seafood could drop by 30 per cent for low-income countries by the end of the century due to climate change, suggests new research. That's in a high carbon emissions and low mitigation scenario, according to the study. This could be reduced to a roughly 10 per cent decline if the world were to meet the Paris Agreement targets of limiting global warming to 1.5 to 2 degrees Celsius -- which recent reports have shown we're not on track to achieve.
Published Engineers develop an efficient process to make fuel from carbon dioxide
(via sciencedaily.com) Original source Researchers developed an efficient process that can convert carbon dioxide into formate, a nonflammable liquid or solid material that can be used like hydrogen or methanol to power a fuel cell and generate electricity.
Published Window to avoid 1.5°C of warming will close before 2030 if emissions are not reduced
(via sciencedaily.com) Original source Without rapid carbon dioxide emission reductions, the world has a 50% chance of locking in 1.5°C of warming before 2030.
Published A sustainable alternative to air conditioning
(via sciencedaily.com) Original source As the planet gets hotter, the need for cool living environments is becoming more urgent. But air conditioning is a major contributor to global warming since units use potent greenhouse gases and lots of energy. Now, researchers have found in a new study an inexpensive, sustainable alternative to mechanical cooling with refrigerants in hot and arid climates, and a way to mitigate dangerous heat waves during electricity blackouts.
Published Heat-related cardiovascular deaths in the U.S. may more than double within decades
(via sciencedaily.com) Original source In nationwide projections, elderly and Black adults are most at risk for cardiovascular death due to extreme heat, finds a new study.
Published Selenium reduces mixtures of environmental pollutants' harmful effects on health
(via sciencedaily.com) Original source A study in mice demonstrates that exposure to contaminating mixtures of metals and drug residue increases damage to health, and evaluates the positive effects of a diet enriched in selenium to reduce this harm.
Published Drawing a tube of blood could assess ALS risk from environmental toxin exposure
(via sciencedaily.com) Original source Investigators have developed a new risk score that assesses a person's risk for developing ALS, as well as for survival after diagnosis, using a blood sample based on exposure to toxins in the environment, a new study shows.
Published Increasing risk of invasive species colonization on marine debris
(via sciencedaily.com) Original source A groundbreaking scientific study conducted along the Southeast coast of India has unearthed a pressing environmental concern -- the increasing risk of invasive species colonization on marine debris. The research delves into the critical interplay between plastic pollution and the introduction of non-indigenous organisms into Indian waters.
Published AI can alert urban planners and policymakers to cities' decay
(via sciencedaily.com) Original source As urbanization advances around the globe, the quality of the urban physical environment will become increasingly critical to human well-being and to sustainable development initiatives. However, measuring and tracking the quality of an urban environment, its evolution and its spatial disparities is difficult due to the amount of on-the-ground data needed to capture these patterns.
Published Meltwater flowing beneath Antarctic glaciers may be accelerating their retreat
(via sciencedaily.com) Original source A new Antarctic ice sheet modeling study suggests that meltwater flowing out to sea from beneath Antarctic glaciers is making them lose ice faster.
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 3D printed reactor core makes solar fuel production more efficient
(via sciencedaily.com) Original source Using a new 3D printing technique, researchers have developed special ceramic structures for a solar reactor. Initial experimental testing show that these structures can boost the production yield of solar fuels.
Published Breakthrough synthesis method improves solar cell stability
(via sciencedaily.com) Original source A new process yields 2D halide perovskite crystal layers of ideal thickness and purity through dynamic control of the crystallization process -- a key step toward ensuring device stability for optoelectronics and photovoltaics.
