Published Researchers find clue to help plants grow with low phosphorus levels
(via sciencedaily.com) Phosphorus is a natural mineral found in fertilizer that is essential for plant growth and development, and Earth's agricultural-grade phosphorus reserves are expected to be depleted in 50 to 100 years. A new discovery is changing their understanding of iron toxicity in plants caused by low phosphorus levels.
Published More predictable renewable energy could lower costs
(via sciencedaily.com) Lower electricity costs for consumers and more reliable clean energy could be some of the benefits of a new study by researchers who have examined how predictable solar or wind energy generation is and the impact of it on profits in the electricity market.
Published Climate change threatens global fisheries
(via sciencedaily.com) The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
Published Habitat will dictate whether ground beetles win or lose against climate change
(via sciencedaily.com) The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.
Published Global natural history initiative builds groundbreaking database to address 21st century challenges
(via sciencedaily.com) A group of natural history museums has mapped the total collections from 73 of the world's largest natural history museums in 28 countries. This is the first step of an ambitious effort to inventory global holdings that can help scientists and decision makers find solutions to urgent, wide-ranging issues such as climate change, food insecurity, human health, pandemic preparedness, and wildlife conservation.
Published The global economics of climate action
(via sciencedaily.com) Climate change has serious consequences for the environment and people and is a major threat to economic stability. A new assessment reviews innovative, integrated research that underpins the economic case for strong near-term climate action.
Published Microplastics limit energy production in tiny freshwater species
(via sciencedaily.com) Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows.
Published Improved wastewater treatment could lead to significant reduction in greenhouse gas emissions
(via sciencedaily.com) New research has shown that methane emissions from urban areas are underestimated by a factor of three to four and that untreated wastewater may be a contributing factor.
Published What really matters in multi-story building design?
(via sciencedaily.com) The impact of multi-story building design considerations on embodied carbon emissions, cost, and operational energy has been revealed.
Published At least 80% of the world's most important sites for biodiversity on land currently contain human developments
(via sciencedaily.com) At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.
Published Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability
(via sciencedaily.com) Large amounts of plastic waste are incinerated or deposited in landfills. This degrades the environment and depletes valuable resources. In this light, recycling plastics such as polymers is promising. However, recycling diminishes their quality. Recently, researchers have proposed a 'closed-loop' recycling process based on polymer microparticles. It produces fully recyclable polymer films with high mechanical stability and fracture energy, which they retain upon recycling.
Published New wood-based technology removes 80% of dye pollutants in wastewater
(via sciencedaily.com) Researchers have developed a new method that can easily purify contaminated water using a cellulose-based material. This discovery could have implications for countries with poor water treatment technologies and combat the widespread problem of toxic dye discharge from the textile industry.
Published Pressure-based control enables tunable singlet fission materials for efficient photoconversion
(via sciencedaily.com) Applying hydrostatic pressure as an external stimulus, researchers demonstrate a new way to regulate singlet fission (SF), a process in which two electrons are generated from a single photon, in chromophores, opening doors to the design of SF-based materials with enhanced (photo)energy conversion. Their method overrides the strict requirements that limit the molecular design of such materials by realizing an alternative control strategy.
Published Without this, plants cannot respond to temperature
(via sciencedaily.com) Scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair.
Published Genome of a drought-tolerant plant: Many genes are involved in 'resurrection'
(via sciencedaily.com) Some plants can survive months without water, only to turn green again after a brief downpour. A recent study shows that this is not due to a 'miracle gene.' Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.
Published Drought, heat waves worsen West Coast air pollution inequality
(via sciencedaily.com) A new study found drought and heat waves could make air pollution worse for communities that already have a high pollution burden in California, and deepen pollution inequalities along racial and ethnic lines. The study also found financial penalties for power plants can significantly reduce people's pollution exposure, except during severe heat waves.
Published Robotic system offers hidden window into collective bee behavior
(via sciencedaily.com) Researchers have developed a temperature-modulating robotic system that can be seamlessly integrated into notoriously sensitive honeybee hives, providing both a never-before-seen view of honeybee behavior and a means to influence it.
Published Global experts propose a path forward in generating clean power from waste energy
(via sciencedaily.com) Scientists have created a comprehensive 'roadmap' to guide global efforts to convert waste energy into clean power.
Published Road noise makes your blood pressure rise -- literally
(via sciencedaily.com) If you live near a busy road you might feel like the constant sound of roaring engines, honking horns and wailing sirens makes your blood pressure rise. Now a new study confirms it can do exactly that.
Published Babies or beauty? Ancient origin of how female butterflies invest
(via sciencedaily.com) When resources are scarce, most animals have to choose. A new study reveals an ancient origin to how female butterflies invest.
