Published Education and information can increase the acceptance of climate policies
(via sciencedaily.com) Original source An important question for policymakers worldwide is how to make climate and environmental policies acceptable among the populations. A new study sheds light on the preferences in five East African countries. The study shows, among others, that education and information about how revenues from carbon taxes are used are important factors.
Published How waves and mixing drive coastal upwelling systems
(via sciencedaily.com) Original source Large coastal upwelling systems along the eastern margins of the Atlantic and Pacific Oceans are among the most biologically productive and biodiverse regions of the world's oceans. Typically, the strength and timing of upwelling in such systems are linked to the prevailing winds. Interestingly, in some tropical regions, high levels of productivity occur even when the upwelling favorable winds are weak.
Published Coal-based product could replace sand in concrete
(via sciencedaily.com) Original source A new study found that graphene derived from metallurgical coke, a coal-based product, through flash Joule heating could serve not only as a reinforcing additive in cement but also as a replacement for sand in concrete.
Published Achieving sustainable urban growth on a global scale
(via sciencedaily.com) Original source An international group of leading scientists call for an urgent change in the governance of urban expansion as the world's cities continue to grow at unprecedented rates.
Published Permeable pavements could reduce coho-killing tire pollutants
(via sciencedaily.com) Original source The pore-like structure of permeable pavements may help protect coho salmon by preventing tire wear particles and related contaminants from entering stormwater runoff, according to a recent study. Researchers demonstrated that four types of permeable pavements can act as giant filters, retaining more than 96% of applied tire particle mass. They also captured several tire-associated chemicals, resulting in a 68% average reduction of 6PPD-quinone, a contaminant shown to kill coho salmon in urban streams.
Published Women exposed to toxic metals may experience earlier aging of their ovaries
(via sciencedaily.com) Original source Middle-aged women who are exposed to toxic metals may have fewer eggs in their ovaries as they approach menopause, according to new research.
Published Less is more: Less greenhouse gas, lower energy consumption, higher wellbeing
(via sciencedaily.com) Original source A new commentary highlights that switching the focus from how energy is supplied to how energy is consumed can be a more effective approach to reducing carbon emissions with the added benefit of improving wellbeing for all.
Published Teaching nature to break human-made chemical bonds
(via sciencedaily.com) Original source A newly evolved enzyme could one day make silicone compounds biodegradable.
Published Diverse forests are best at standing up to storms
(via sciencedaily.com) Original source European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published New research challenges hunter-gatherer narrative
(via sciencedaily.com) Original source Analysis of the remains of 24 individuals from the Wilamaya Patjxa and Soro Mik'aya Patjxa burial sites in Peru shows that early human diets in the Andes Mountains were composed of 80 percent plant matter and 20 percent meat.
Published DNA from preserved feces reveals ancient Japanese gut environment
(via sciencedaily.com) Original source DNA from ancient feces can offer archaeologists new clues about the life and health of Japanese people who lived thousands of years ago, according to a new study.
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web
(via sciencedaily.com) Original source Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Humpback whales move daytime singing offshore
(via sciencedaily.com) Original source New research revealed a daily pattern wherein humpback whales move their singing away from shore throughout the day and return to the nearshore in the evening.
Published Self-powered movable seawall for tsunami protection and emergency power generation
(via sciencedaily.com) Original source A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in natural disasters. This innovative system integrates disaster prevention with the use of renewable energy.
Published Global warming has a bigger effect on compact, fast-moving typhoons
(via sciencedaily.com) Original source A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.
Published Researchers advocate for sustainable logging to safeguard against global flood risks
(via sciencedaily.com) Original source It's time to recognize the power of healthy forests in managing global growing flood risk, and to shift towards more sustainable forestry practices and policy.
Published A new design improves water decontamination via plasma jet
(via sciencedaily.com) Original source Two research groups design a plasma (an ionized gas) reactor maintained by microwaves that makes it possible to decontaminate waters with high concentrations of dye.
Published War in Ukraine severely limits ability to track Arctic climate change
(via sciencedaily.com) Original source Scientists no longer have direct access to data from Russian Arctic research stations. Without this data, our view of climate changes in the region is increasingly biased, new research shows.
Published Ancient brown bear genomes sheds light on Ice Age losses and survival
(via sciencedaily.com) Original source The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyena), the brown bear is one of the lucky survivors that made it through to the present. The question has puzzled biologists for close to a century -- how was this so?
Published A large percentage of European plastic sent to Vietnam ends up in nature
(via sciencedaily.com) Original source Despite strict EU regulations on plastic recycling, there is little oversight on plastic waste shipped from the EU to Vietnam. A large percentage of the exported European plastic cannot be recycled and gets dumped in nature, according to recent research.
