Published New study unveils 16,000 years of climate history in the tropical Andes (via sciencedaily.com) Original source
Researchers highlight the roles of carbon dioxide and ocean currents as key drivers of temperature fluctuations in the tropical Andes over a 16,000 year period.
Published Forest restoration can boost people, nature and climate simultaneously (via sciencedaily.com) Original source
Forest restoration can benefit humans, boost biodiversity and help tackle climate change simultaneously, new research suggests.
Published Mature forests vital in frontline fight against climate change (via sciencedaily.com) Original source
Mature forests have a key role to play in the fight against climate change -- extracting carbon dioxide (CO2) from the atmosphere and locking it into new wood.
Published Balancing technology and governance are key to achieving climate goals (via sciencedaily.com) Original source
Despite advancements in clean energy, global CO2 emissions continue to rise. IIASA researchers contributed to a new international study that underscores the importance of integrating technological advancements with robust institutional capacities to formulate effective climate policies.
Published Drug protects against air pollution-related Alzheimer's signs in mice (via sciencedaily.com) Original source
A new study shows how feeding mice a drug called GSM-15606 provided protection against air pollution-related increases in proteins linked to Alzheimer's disease.
Published Just say 'climate change' -- not 'climate emergency' (via sciencedaily.com) Original source
The familiar terms 'climate change' and 'global warming' are more likely to resonate with people than other commonly used phrases.
Published New genetically engineered wood can store carbon and reduce emissions (via sciencedaily.com) Original source
Researchers genetically modified poplar trees to produce high-performance, structural wood without the use of chemicals or energy intensive processing.
Published As temperatures break records, many are unaware of symptoms of heat-related illnesses (via sciencedaily.com) Original source
Following record breaking heat, a survey reveals that most Americans do not know where their local cooling centers are in cases of extreme heat.
Published Canadian wildfires are affecting US air quality and raising health concerns (via sciencedaily.com) Original source
Climate-driven wildfire events are rapidly transferring harmful particulate matter containing toxic chemicals over long distances, compromising air quality in the New Jersey and New York City areas, according to recent research.
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 Researchers find unexpectedly large methane source in overlooked landscape (via sciencedaily.com) Original source
Researchers reported that upland landscapes were releasing some of the highest methane emissions yet documented among northern terrestrial ecosystems. The research was sparked when a potent greenhouse gas began ballooning under lawns in Fairbanks.
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 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.
