A new study has quantified the risk for whale-ship collisions worldwide for four blue, fin, humpback and sperm whales. Researchers report that global shipping traffic overlaps with about 92% of these whale species鈥� ranges. Only about 7% of areas at highest risk for whale-ship collisions have measures in place to protect whales.
For the past decade, Jos茅 Ram铆rez-Garofalo, a doctoral candidate in the Department of Ecology, Evolution and Natural Resources in the Rutgers School of Environmental and Biological Sciences, has tramped through swamps and meadows in the tri-state metropolitan area looking for signs of environmental change, including signs of new species, insect and otherwise.
In a session of the 187th ASA Meeting, Michael Stocker of Ocean Conservation Research will present work examining the circumstances surrounding the whale deaths off the coast of New Jersey in the winter of 2022-23, which prompted concern that survey work in the area somehow contributed to their deaths.
Researchers at The University of Alabama in Huntsville (UAH) have employed a NASA open-source program to reveal that disadvantaged populations may be subject to greater heat stress and poor air quality. For this study, the researchers focused on Houston, Tex. Combining changes in heat and land cover with Houston's socioeconomic data demonstrated that economically disadvantaged populations are subject to greater heat stress.
In July 1982, researchers in New Zealand recorded unidentifiable sounds as a part of an experiment to characterize the soundscape of the South Fiji Basin. The sound consisted of four short bursts resembling a quack, which inspired the name of the sound 鈥淏io-Duck,鈥� and researchers came to a consensus that the sounds had to be biological. Ross Chapman will present his work analyzing the mystery sounds as part of the virtual 187th ASA Meeting, presenting the waveform and spectrum of the recordings, as well as further evidence that the work was a conversation between multiple animals.
A new study reveals how sunlight can drive the purification of lake water by breaking down harmful contaminants. By comparing two photochemical pathways鈥攖riplet sensitization and direct photolysis鈥攖he research highlights how these mechanisms function differently across various lake environments. The study points out that while certain pollutants are degraded through organic carbon interactions, others rely heavily on sunlight intensity, suggesting a combined strategy for more effective water purification.
Morning glory plants that can resist the effects of glyphosate also resist damage from herbivorous insects, according to a University of Michigan study.
Dr. Hyang-Tag Lim's research team at the KIST has implemented a quantum computing algorithm that can estimate interatomic bond distances and ground state energies with chemical accuracy using fewer resources than conventional methods, and has succeeded in performing accurate calculations without the need for additional quantum error mitigation techniques.
A new program at Wayne State University supported by a four-year, $749,991 grant from the National Institute of Food and Agriculture of the United States Department of Agriculture (USDA) will use data to study the future of agriculture and train students to better understand how to keep people fed in an ever-changing world.
Over a typical two-year rotation of corn and soybeans, 40% of nitrous oxide emissions are in the fertilizer-free soybean year, according to new Iowa State University research. Winter cover crops and planting soybeans earlier could reduce emissions of the potent greenhouse gas by one-third while increasing yields.
A report out today by聽The Washington Post finds most cities in the United States are not prepared for climate change. ...
WCS welcomes this scientific opinion by the Group of Chief Scientific Advisors (GCSA), which provides recommendations to support the successful implementation of European Union (EU) policies deriving from a One Health approach.
Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources.
A groundbreaking review article delves into the critical challenges facing electric vehicle (EV) battery technology, offering insights into current research trends and future advancements. The study examines the performance, safety, and environmental impact of various battery types, including lithium-ion and solid-state batteries. It also explores innovative management techniques and highlights the importance of developing cost-effective, sustainable, and safe battery solutions to support the growth of electric mobility.
Flying robots capable of inspecting and repairing building envelopes, interacting with natural ecosystems, and monitoring climate change and biodiversity are being developed and tested at the DroneHub at Empa's NEST.
Geology researchers at The University of Texas at El Paso are partnering with scientists in the Kingdom of Bhutan to detect and mitigate the impact of glacial floods on rural mountain villages. The new project is supported by approximately $380,000 from the National Science Foundation.
In this week鈥檚 Physics of Fluids, researchers employ machine learning to more accurately model the boundary layer wind field of tropical cyclones. Conventional approaches to storm forecasting involve large numerical simulations run on supercomputers incorporating mountains of observational data, and they still often result in inaccurate or incomplete predictions. In contrast, the author鈥檚 machine learning algorithm is equipped with atmospheric physics equations that can produce more accurate results faster and with less data.
A few years back, a group of weed scientists showed that soil-applied herbicides are less effective against agricultural weeds in the context of our changing climate. Now, the same research group, led by the USDA Agricultural Research Service and the University of Illinois Urbana-Champaign, has shown the same is true of post-emergence (POST) herbicides.
