Published Recycling carbon dioxide into household chemicals



Scientists report a family of tin-based catalysts that efficiently converts CO2 into ethanol, acetic acid and formic acid. These liquid hydrocarbons are among the most produced chemicals in the U.S and are found in many commercial products.
Published Rabies outbreaks in Costa Rica cattle linked to deforestation



Deforestation in Costa Rica raises the risk of cattle becoming infected with rabies by vampire bats, finds a new study.
Published Green infrastructure plans need to consider historical racial inequalities



Urban greening projects should consider historical development patterns and past discriminatory practices to avoid exacerbating the unequal distribution of environmental benefits, says an urban and regional planning professor.
Published Highly sensitive fiber optic gyroscope senses rotational ground motion around active volcano



Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, Italy. A better understanding of the seismic activity in this highly populated area could improve risk assessment and might lead to improved early warning systems.
Published Warming climate intensifies flash droughts worldwide



Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.
Published Electric school buses may yield significant health and climate benefits, cost savings



Replacing diesel school buses with electric school buses may yield up to $247,600 in climate and health benefits per individual bus, according to a new study. The researchers found that these benefits -- including fewer greenhouse gas emissions and reduced rates of adult mortality and childhood asthma -- and their associated savings are strongest in large cities and among fleets of old (2005 and before) buses.
Published 'Vigorous melting' at Antarctica's Thwaites 'Doomsday' Glacier



Glaciologists show evidence of warm ocean water intruding kilometers beneath grounded ice at Thwaites Glacier in West Antarctica. The findings suggest that existing climate models are underestimating the impact of ocean and ice interactions in future sea level rise projections.
Published The impacts of climate change on food production



A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
Published Digging up good news for microbial studies



Findings indicate that soil stored under refrigerated or air-dried conditions can still retain the needed information for understanding microbial community composition and structure for many years.
Published Extreme heat associated with children's asthma hospital visits



Extreme heat events were associated with increased asthma hospital visits, according to new research.
Published Unraveling the drought dilemma: Can reservoirs be a carbon source?



A team delves into the spatiotemporal patterns of water volume and total organic carbon concentration of agricultural reservoirs.
Published Decarbonization dynamics: New analysis unveils shifting trends in the voluntary carbon offset market



Researchers have conducted a worldwide analysis of voluntary carbon offset programs and identified trends into which types of carbon reduction technologies are selected and prioritized. Their findings provide important insights for policymakers to improve the effectiveness and credibility of the carbon offset market.
Published U.S. drought-monitoring system outpaced by climate changes



A new study reports that the U.S. Drought Monitor's weekly maps of nationwide drought conditions -- which help direct emergency federal aid -- have captured the steady march of climate change, but the Drought Monitor has itself failed to adapt to that reality. Areas of the country are spending more and more time in severe drought conditions the Drought Monitor still considers to be rare occurrences. The consequences could be that swaths of the country -- particularly in the West -- may not receive aid in keeping with the enhanced risk of drought as periodic emergencies become persistent new realities.
Published Record low Antarctic sea ice 'extremely unlikely' without climate change



Scientists have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year event without climate change and four times more likely under its effects.
Published Expanding on the fundamental principles of liquid movement



We are living in a world surrounded by liquid and flow, and understanding the principles that govern its movement is vital in our high-tech world. Through mathematical modeling and experimentation, researchers have expanded on Tanner's Law -- a law in fluid dynamics that describes how non-volatile liquids move across surfaces -- to cover a wider range of volatile liquids. These findings have the potential to play a role in various liquid-based industries such as electronics cooling.
Published Scientists develop new geochemical 'fingerprint' to trace contaminants in fertilizer



An international team of scientists has revealed high levels of toxic metals in global phosphate fertilizers using a isotopic variants of the element strontium as a tracer to uncover metals in soil, groundwater and possibly the food chain.
Published Scale matters in determining vulnerability of freshwater fish to climate changes



A team explored the influence the spatial extent of research -- the geographical coverage of data collected -- has on evaluating the sensitivity of different fish species to climate change.
Published How heatwaves are affecting Arctic phytoplankton



The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic. The phytoplankton's behavior primarily depends on the cooling phases after or between heatwaves.
Published Differing values of nature can still lead to joined up goals for sustainability



Recognizing and respecting the different ways nature is valued can enable better environmental decision-making, according to new research.
Published Can we revolutionize the chemical industry and create a circular economy? Yes, with the help of catalysts



A new commentary paper puts forth a transformative solution to the unsustainable reliance on fossil resources by the chemical industry: catalysis to leverage sustainable waste resources, ushering the industry from a linear to a circular economy.
