Andrew Margenot led some of the top biogeochemists from around the world in synthesizing recommendations for measuring phosphorus accumulation in the biosphere.
On the heels of a Northeastern rainstorm that flooded towns on Long Island and claimed at least two lives in Connecticut, teams of scientists, engineers, and representatives of local power and transportation utilities met to discuss the increasing frequency of severe weather and its impacts on crucial infrastructure. The timing for the meeting at New York’s Kennedy International Airport August 21-22, 2024, was a coincidence.
Scientists using high-resolution aerial scans and computational modeling concluded that wildfires, storms and selective logging have become key drivers behind rainforest carbon emissions, outpacing clear-cutting practices.The team used drones equipped with light detection and ranging sensors, or LiDAR, to measure tree biomass and carbon emissions in Brazilian forests.
Redlining from the 1930s, marked minority and low-income neighborhoods as “hazardous,” which influenced mortgage and insurance decisions. Results show that redlined areas have less greenspace and more pavement, intensifying urban heat. While higher temperatures generally decreased walking in “still desirable” or “best” neighborhoods, this effect was not significant in “definitely declining” or “hazardous” areas, possibly due to greater reliance on walking for essential activities. Findings underscore the lasting impact of discriminatory policies on environmental vulnerability and physical activity.
Increased capabilities in the human-occupied submersible Alvin open a window on a rarely seen behavior
Researchers in ACS Central Science report a sugar-like polymer that traps heavy metals within insoluble clumps for easy removal. In proof-of-concept tests, the polymer removed ionic cadmium and lead from river water spiked with these persistent contaminants.
KIMM develops seawater-based self-charging energy harvester. Newly developed energy harvester, which is capable of generating 4.2 times more electrical power compared with existing devices, is expected to be used for small-sized equipment such as devices for monitoring ocean environments
Land was once set aside as Native American reservations because it was undesirable and low in resources, but now interested Native Americans may have economic leverage in the growing industry of clean energy. A team of researchers led by UW–Madison professors Dominic Parker and Sarah Johnston quantified the economic potential of wind and solar energy projects on these lands and discussed the regulatory barriers for tribes wishing to tap into it.
Cal Poly Humboldt Forestry Professor Jeff Kane is leading a project funded by the USDA Forest Service in collaboration with Ecologist, Kyle Merriam, to reestablish Baker Cypress in areas where it was nearly extirpated by the 2021 Dixie Fire, with significant involvement from students.
The research aims to assess changes in surface fuels, tree mortality, regeneration, and the general health of secondary redwood forests.
Scientists from Jefferson Lab, Old Dominion University and the University of Virginia recently conducted a study that compares deep learning models of street-scale flooding in the City of Norfolk with previous machine learning and physics-based simulations.
Predators not native to Madagascar, such as feral dogs and cats, may pose a serious threat to lemur species—many of which are already facing extinction on this African island.
Wildfires continue to rage in parts of California and Nevada forcing mandatory evacuations for homes nearby. ...
Scientists report that underwater noise pollution — from both large and small vessels — forces northern and southern resident orcas to expend more time and energy hunting for fish. The din also lowers the overall success of their hunting efforts. Noise from ships likely has an outsized impact on southern resident orca pods, which spend more time in areas with high ship traffic.
Historically, Lake Okeechobee was thought to be impaired only by phosphorus, focusing efforts on reducing agricultural runoff. However, new comprehensive sampling across the Lake Okeechobee Waterway and its connected estuaries shows that toxic algal blooms also are driven by rising nitrogen levels from human waste and urban runoff. Increased nitrogen, worsened by extreme rainfall, significantly fuels bloom severity. Findings underscore the need for integrated nutrient management and improved wastewater treatment to protect the lake and its estuaries.
A recent study unveils new insights into the complex regulatory mechanisms behind strawberry fruit ripening. By analyzing histone modifications, researchers have mapped a detailed chromatin structure model that governs the ripening process, emphasizing the critical role of histone acetylation in regulating gene expression during fruit maturation. This breakthrough could lead to strategies for improving strawberry quality and shelf life, with potential applications for other fruits.
Lakes provide drinking water, food, recreation and mental health benefits to people who use them or live nearby. Regular monitoring of water quality is essential to collect information to track lake health. Without this information, people who use the lakes may be at a higher risk if water quality is poor.
Land beneath the city in Los Angeles County has been slowly shifting for decades, a peninsula that is especially vulnerable to wind and weather that also happens to sit on a fault line. ...
Dr. Jatuwat Sangsanont from the Department of Environmental Science at the Faculty of Science, Chulalongkorn University, has been awarded the United Nations Public Service Awards (UNPSA 2024) in the ‘Innovation in Public Institutions’ category.
A newly published article spells out the work needed to assess the potential of ocean iron fertilization as a low cost, scalable, and rapidly deployable method of mCDR.
