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 New battery technology could lead to safer, high-energy electric vehicles
(via sciencedaily.com) Original source Researchers studying how lithium batteries fail have developed a new technology that could enable next-generation electric vehicles (EVs) and other devices that are less prone to battery fires while increasing energy storage.
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 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 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 75% of exclusive hardwood may be illegally harvested
(via sciencedaily.com) Original source The tropical wood type ipe is popular for building exclusive wooden decks, and in North America and Europe, the demand for the material has increased sharply. Now, a study shows that more than three-quarters of all ipe from the top producing region in Brazil could have been harvested illegally.
Published Endangered whales live in area earmarked for gas exploration
(via sciencedaily.com) Original source Endangered whales and dolphins live year-round in an area of the Mediterranean earmarked for oil and gas exploration, new research shows.
Published A potentially cheaper and 'cooler' way for hydrogen transport
(via sciencedaily.com) Original source Researchers have developed a new hydrogen energy carrier material capable storing hydrogen energy efficiently and potentially more cheaply. Each molecule can store one electron from hydrogen at room temperature, store it for up the three months, and can be its own catalyst to extract said electron. Moreover, as the compound is made primarily of nickel, its cost is relatively low.
Published Do or dye: Synthetic colors in wastewater pose a threat to food chains worldwide
(via sciencedaily.com) Original source Dyes widely used in the textile, food and pharmaceutical industries pose a pressing threat to plant, animal and human health, as well as natural environments around the world, a new study has found. Billions of tons of dye-containing wastewater enter water systems every year, and a group of researchers say that new sustainable technologies including new membrane-based nano-scale filtration are needed to solve the issue, adding that legislation is needed to compel industrial producers to eliminate colorants before they reach public sewage systems or waterways.
Published Analysis finds diversity on the smallest scales in sulfur-cycling salt marsh microbes
(via sciencedaily.com) Original source Scientists have discovered that even among the sulfur-cycling microbes that are responsible for the 'rotten egg gas' smell in salt marsh air, diversity extends all the way to genomes and even to individual nucleotides.
Published Algae's surprising potential to help ease climate change worries
(via sciencedaily.com) Original source The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.
Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com) Original source New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
Published Climate change likely impacted human populations in the Neolithic and Bronze Age
(via sciencedaily.com) Original source Human populations in Neolithic Europe fluctuated with changing climates, according to a new study.
Published UK air pollution regulations will reduce deaths, but do little to protect ecosystems
(via sciencedaily.com) Original source Existing air pollution regulations will reduce thousands of premature adult deaths in the UK, but even the most effective technically feasible actions, which will save thousands more lives, will do little to protect the country's sensitive ecosystems, find researchers.
Published Single model predicts trends in employment, microbiomes, forests
(via sciencedaily.com) Original source Researchers report that a single, simplified model can predict population fluctuations in three unrelated realms: urban employment, human gut microbiomes and tropical forests. The model will help economists, ecologists, public health authorities and others predict and respond to variability in multiple domains.
Published Report warns about risk tipping points with irreversible impacts on people and planet
(via sciencedaily.com) Original source A new report finds that drastic changes are approaching if risks to our fundamental socioecological systems are not addressed. The Interconnected Disaster Risks Report 2023 warns of six risk tipping points ahead of us: Accelerating extinctions; Groundwater depletion; Mountain glaciers melting; Space debris; Unbearable heat; and an Uninsurable future.
Published A sustainable future is based on a learning society
(via sciencedaily.com) Original source A holistic transformation is needed for the planet to accommodate people's pursuit of well-being. A new study explores a Theory of Planetary Social Pedagogy as a driver of a transformative process based on a learning society.
Published Diapers can be recycled 200 times faster with light
(via sciencedaily.com) Original source More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers. Researchers have now succeeded in considerably improving their complex recycling process. They use UV radiation to degrade the chemical chains that keep the polymers together. No chemicals are needed. Recycling at room temperature is 200 times faster than conventional recycling. The recycled polymers can then be processed to new adhesives and dyes.
