Published Nanophotonics: Coupling light and matter
(via sciencedaily.com) Original source Researchers have developed a metasurface that enables strong coupling effects between light and transition metal dichalcogenides (TMDCs).
Published Effect of volcanic eruptions significantly underestimated in climate projections
(via sciencedaily.com) Original source Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.
Published Traditional methods cannot give us the insights we need to understand changing ecosystems
(via sciencedaily.com) Original source If we want to face up to the challenges posed by climate change and other global environmental changes, we need to bring complexity science into the mix with ecology and biodiversity conservation.
Published Perovskite solar cells set new record for power conversion efficiency
(via sciencedaily.com) Original source Perovskite solar cells have attained now attained the extremely high efficiency rate of 24.35% with an active area of 1 cm2. This ground-breaking achievement in maximizing power generation from next-generation renewable energy sources will be crucial to securing the world's energy future.
Published Will engineered carbon removal solve the climate crisis?
(via sciencedaily.com) Original source A new study explored fairness and feasibility in deep mitigation pathways with novel carbon dioxide removal, taking into account institutional capacity to implement mitigation measures.
Published Potential financial losses from a renewable energy transition are concentrated among the wealthy
(via sciencedaily.com) Original source One common rationale against climate action is that the resulting fossil fuel investment losses could impact people's retirement or long-term savings. However, researchers report that the loss of fossil fuel assets would have a minimal impact on the general populace. In high-income countries, most financial losses would be borne by the most affluent individuals for whom the loss makes up a small percentage of their total wealth. In contrast, the financial loss of lower-income individuals would be minimal and feasible for governments to compensate.
Published Conservation policies risk damaging global biodiversity, researchers argue
(via sciencedaily.com) Original source Rewilding, organic farming and the 'nature friendly farming' measures included in some government conservation policies risk worsening the global biodiversity crisis by reducing how much food is produced in a region, driving up food imports and increasing environmental damage overseas.
Published Rain gardens could save salmon from toxic tire chemicals
(via sciencedaily.com) Original source Specially designed gardens could reduce the amount of a toxic chemical associated with tires entering our waterways by more than 90 per cent, new research shows.
Published 'Shoebox' satellites help scientists understand trees and global warming
(via sciencedaily.com) Original source As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental scientists make more precise measurements about trees' response to a warming climate.
Published Inside-out heating and ambient wind could make direct air capture cheaper and more efficient
(via sciencedaily.com) Original source Chemical engineers use coated carbon fibers and eliminate steam-based heating in their simpler design, which also can be powered by wind energy.
Published Antarctic ice shelves experienced only minor changes in surface melt since 1980
(via sciencedaily.com) Original source A team of glaciologists set out to quantify how much ice melt occurred on Antarctica's ice shelves from 1980 to 2021. The results might seem to be good news for the region, but the researchers say there's no cause for celebration just yet.
Published Smart farming platform improves crop yields, minimizes pollution
(via sciencedaily.com) Original source A new farming system aims to solve one of the biggest problems in modern agriculture: the overuse of fertilizers to improve crop yields and the resulting chemical runoff that pollutes the world's air and water.
Published Wildfire smoke downwind affects health, wealth, mortality
(via sciencedaily.com) Original source Smoke particulates from wildfires could cause between 4,000 and 9,000 premature deaths and cost between $36 to $82 billion per year in the United States, according to new research.
Published Vastly more sustainable, cost-effective method to desalinate industrial wastewater
(via sciencedaily.com) Original source Engineers are developing a cutting-edge process that can reduce energy consumption and cost of water desalination.
Published Drug-resistant fungi are thriving in even the most remote regions of Earth
(via sciencedaily.com) Original source New research has found that a disease-causing fungus -- collected from one of the most remote regions in the world -- is resistant to a common antifungal medicine used to treat infections.
Published Caribbean seagrasses provide services worth $255B annually, including vast carbon storage, study shows
(via sciencedaily.com) Original source Caribbean seagrasses provide about $255 billion in services to society annually, including $88.3 billion in carbon storage, according to a new study. The study has put a dollar value on the many services -- from storm protection to fish habitat to carbon storage -- provided by seagrasses across the Caribbean, which holds up to half the world's seagrass meadows by surface area and contains about one-third of the carbon stored in seagrasses worldwide.
Published The art and science of living-like architecture
(via sciencedaily.com) Original source Collaborators have created 'living-like' bioactive interior architecture designed to one day protect us from hidden airborne threats. This publication establishes that the lab's biomaterial manufacturing process is compatible with the leading-edge cell-free engineering that gives the bioactive sites their life-like properties.
Published Engineers 'strike gold' with innovation that recovers heavy metals from biosolids
(via sciencedaily.com) Original source Engineers have developed a cost-effective and environmentally friendly way to remove heavy metals, including copper and zinc, from biosolids. The team's work advances other methods for heavy-metal removal by recycling the acidic liquid waste that is produced during the recovery phase, instead of throwing it away.
Published Environmental risks and opportunities of orphaned oil and gas wells
(via sciencedaily.com) Original source Researchers are leading an international team whose goal is to create a framework to help governments in the U.S. and around the world assess and prioritize remediation strategies for orphaned oil and gas wells. These inactive wells represent environmental risks since they have the potential to contaminate water supplies, degrade ecosystems, and emit methane and other air pollutants that are harmful to human health. But plugging the wells also offers various potential environmental opportunities such as underground storage of carbon dioxide and hydrogen, or the development of geothermal energy systems.
Published New research reveals the impact of different species and their traits on human wellbeing
(via sciencedaily.com) Original source New research has revealed that well-functioning ecosystems are crucial to human health and wellbeing, with human-biodiversity interactions delivering wellbeing gains equating to substantial healthcare cost-savings, when scaled-up across populations.
