Jet stream changes could amplify weather extremes by 2060s

New research provides insights into how the position and intensity of the North Atlantic jet stream has changed during the past 1,250 years. The findings suggest that the position of the jet stream could migrate outside of the range of natural variability by as early as the year 2060 under unabated greenhouse gas emissions, with potentially drastic weather-related consequences for societies on...

Public will pay over $500 million a year for hurricane forecast improvements, study finds

A recent survey of people recently affected by hurricanes across four states found that the public is willing to pay more than $500 million a year to improve hurricane forecasts. The study, led by a group of atmospheric scientists and economists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, comes at a time when Hurricane Ida's path caused widespread damage...

Elephant project recordings evoke the rainforest

More than a million hours of sound recordings are available from the Elephant Listening Project (ELP) in the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology—a rainforest residing in the cloud.

Researchers design sensors to rapidly detect plant hormones

Researchers from the Disruptive and Sustainable Technologies for Agricultural Precision (DiSTAP) interdisciplinary research group of the Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, and their local collaborators from Temasek Life Sciences Laboratory (TLL) and Nanyang Technological University (NTU), have developed the first-ever nanosensor to...

Compound hazards pose increased risk to highly populated regions in the Himalayas

Most of the research concerned with hazards like flooding, landslides, or wildfires describes only one hazard at a time, but the Intergovernmental Panel on Climate Change's latest assessment report states that anthropogenic climate change is increasing the likelihood of compound hazards—events where more than one hazard interact with multiplicatively destructive consequences. A recent study...

Balancing food security and nitrogen use

Environmental targets to limit excess nitrogen require the large-scale deployment of dedicated nitrogen mitigation strategies to avoid a strong increase in the risk of food insecurity. Without these measures, the amount of dietary energy available to people would be greatly reduced, which would in turn lead to high food prices and an increase in the number of undernourished people.

Tongue-in-cheek award with cult status for cinema air study

The Ig Nobel Prizes honor scientific achievements that "should first make people laugh and then make them think". The spoof prizes, first awarded by the US journal Annals of Improbable Research in 1991, have long since acquired cult status among scientists. This year's chemistry award recognizes a study that proves the connection between the air in cinemas and different age ratings. The study was...

Pioneering method of assessing rewilding progress applied for the first time

Scientists from the German Centre for Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU) and Rewilding Europe have developed a new way of evaluating rewilding progress. Its ground-breaking application across seven of Rewilding Europe's operational areas has revealed both positive impact and challenges to upscaling. The practical tool can help to inform...

Crop-eating moths will flourish as climate warms

Climate change in this century will allow one of the world's costliest agricultural pests, the diamondback moth, to both thrive year-round and rapidly evolve resistance to pesticides in large parts of the United States, Europe and China where it previously died each winter, according to a study by U.S. and Chinese researchers.

Genetic resource could be used to protect farm-raised kuruma shrimp from disease

New research from the Okinawa Institute of Science and Technology Graduate University (OIST) and Tokyo University of Marine Science and Technology has resulted in a useful genetic resource on the kuruma shrimp. These are one of the largest species of prawn (females can reach 27cm in length) and are found throughout the Indian and Pacific Oceans. In Japan, they're considered a delicacy and have...

Crews in southern Spain face 'complex' wildfire for 5th day

Firefighting crews in southern Spain are looking at the sky for much-needed rainfall expected on Monday and that they hope can help extinguish a major wildfire that has ravaged 7,700 hectares (19,000 acres) in five days and displaced around 2,600 people from their homes.

Study provides basis to evaluate food subsectors' emissions of three greenhouse gases

A new, location-specific agricultural greenhouse gas emission study is the first to account for net carbon dioxide, methane and nitrous oxide emissions from all subsectors related to food production and consumption. The work, led by University of Illinois Urbana-Champaign atmospheric sciences professor Atul Jain, could help identify the primary plant- and animal-based food sectors contributing to...
