Published New mechanism to cool buildings while saving energy (via sciencedaily.com) Original source
The movement of radiant heat -- felt when a hot surface warms our bodies and homes -- between buildings and their surroundings at ground level makes buildings with less skyward-facing surfaces harder to cool. A research team has demonstrated a new passive cooling technology that coats walls and windows with materials that can better manage heat movement between buildings and their surroundings at ground level. Findings could reduce the reliance on air conditioning and provide a more environmentally friendly, low-cost and scalable option for low-income communities with limited or no access to cooling and heating systems.
Published Millions of years for plants to recover from global warming (via sciencedaily.com) Original source
Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term effects of disturbed natural ecosystems on climate in geological history and its implications for today.
Published Greenland mega-tsunami led to week-long oscillating fjord wave (via sciencedaily.com) Original source
In September 2023, a megatsunami in remote eastern Greenland sent seismic waves around the world, piquing the interest of the global research community. The event created a week-long oscillating wave in Dickson Fjord, according to a new report in The Seismic Record.
Published Nature at risk in the hunt for the perfect selfie (via sciencedaily.com) Original source
The need for a dramatic selfie or the perfect landscape photo is proving detrimental to nature, a new research collaboration has found.
Published Engineering researchers enhance perovskite solar cells durability with first-of-its-kind chiral-structured 'springy' interface (via sciencedaily.com) Original source
A research team has constructed an unprecedented chiral-structured interface in perovskite solar cells, which enhances the reliability and power conversion efficiency of this fast-advancing solar technology and accelerates its commercialization.
Published Pioneering plasma-catalytic process for CO2 hydrogenation to methanol under ambient conditions (via sciencedaily.com) Original source
A research team reports a pioneering plasma-catalytic process for the hydrogenation of CO2 to methanol at room temperature and atmospheric pressure. This breakthrough addresses the limitations of traditional thermal catalysis, which often requires high temperatures and pressures, resulting in low CO2 conversion and methanol yield.
Published 3D laser printing with bioinks from microalgae (via sciencedaily.com) Original source
Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as 'biofactories' for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments. An international research team has succeeded for the first time in manufacturing inks for printing complex biocompatible 3D microstructures from the raw materials extracted from the microalgae.
Published Researchers make breakthrough in understanding species abundance (via sciencedaily.com) Original source
The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.
Published Finding pearls in the mud: Eco-friendly tungsten recovery from semiconductor waste (via sciencedaily.com) Original source
Semiconductor industry waste is typically seen as a costly disposal problem and an environmental hazard. But what if this waste could be transformed into a valuable resource? In an exciting development, researchers have unveiled an eco-friendly method to extract rare metals from semiconductor waste. This innovative approach not only recovers precious tungsten but also assesses its economic viability, offering a sustainable solution for waste management in the tech industry.
Published Effective new catalyst brings hope for cleaner energy, wastewater treatment, and green chemistry (via sciencedaily.com) Original source
A catalyst that significantly enhances ammonia conversion could improve wastewater treatment, green chemical and hydrogen production.
Published Detecting climate change using aerosols (via sciencedaily.com) Original source
Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.
Published Increasing clinicians' knowledge about climate change's impact on health and healthcare sustainability (via sciencedaily.com) Original source
A novel educational program for clinicians provided a foundation about climate change and the impact of fossil fuel-related pollution on individual health, and how healthcare systems contribute to carbon pollution and can address these challenges.
Published Alaskan land eroding faster due to climate change (via sciencedaily.com) Original source
A new study shows that frozen land in Alaska is eroding faster than it can be replaced due to climate change.
Published Individuals vary in how air pollution impacts their mood (via sciencedaily.com) Original source
Affective sensitivity to air pollution (ASAP) describes the extent to which affect, or mood, fluctuates in accordance with daily changes in air pollution, which can vary between individuals, according to a new study.
Published Study quantifies air pollution for NYC subway commuters (via sciencedaily.com) Original source
New York City subway commuters who are economically disadvantaged or belong to racial minority groups have the highest exposure to fine particulate matter during their commutes, according to a new study.
Published Work-from-home success might depend on home office setup (via sciencedaily.com) Original source
In a new survey study, Dutch employees who worked from home tended to report higher levels of productivity and less burnout if they were more satisfied with their home office setup. The study also linked more air ventilation in the home office to higher self-reported productivity.
Published Forever chemical pollution can now be tracked (via sciencedaily.com) Original source
Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.
Published Study on planet-warming contrails 'a spanner in the works' for aviation industry (via sciencedaily.com) Original source
Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found.
Published Used concrete transformed into new bricks while trapping CO2 (via sciencedaily.com) Original source
Researchers have turned concrete from a demolished school building and carbon dioxide (CO2) from the air into new blocks strong enough to build a house with. The process involved grinding the old concrete into powder, reacting it with CO2 from the air, pressurizing it in layers in a mold and finally heating it to form the new block. Instead of making buildings from new concrete only, this technique could offer a way to recycle old materials while also trapping carbon dioxide in the process. The blocks could theoretically be remade again and again, through the same process.
Published Pesticide contamination is more than apple skin deep (via sciencedaily.com) Original source
Pesticides and herbicides are critical to ensuring food security worldwide, but these substances can present a safety risk to people who unwittingly ingest them. Protecting human health, therefore, demands sensitive analytical methods to identify even trace levels of potentially harmful substances. Now, researchers have developed a high-tech imaging method to detect pesticide contamination at low levels, and its application on fruits reveals that current food safety practices may be insufficient.
