Rising mercury pollution in soil could be related to climate change, study suggests
In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty's provisions might not be enough. A stu.....»»
"Mirror" nuclei help connect nuclear theory and neutron stars
Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts. Scientists can use precision measurements of these.....»»
Climate change raised the odds of unprecedented wildfires in 2023–24, say scientists
Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the first edition of a new systematic an.....»»
AI-driven method enhances electron microscopy imaging capabilities of complex biological systems
Electron microscopy has enabled visualization of the intricate details inside cells. The advancement to 3D electron microscopy, known as volume EM (vEM), has further expanded this three-dimensional, nanoscale imaging capacity. However, trade-offs bet.....»»
Starvation and adhesion drive formation of keratinocyte patterns in skin, research reveals
Fingerprints are one of the best-recognized examples of pattern formation by epithelial cells. The primary cells in the epithelium are the keratinocytes, and they are known to form patterns at the microscopic and macroscopic levels. While factors aff.....»»
Researchers highlight the carbon-saving potential of compact cities
In recent years, the dramatic rise in extreme weather events due to climate change has escalated what was once termed "climate change" into a "climate crisis." With global average surface temperatures reaching unprecedented levels, the urgency to tra.....»»
New study unveils 16,000 years of climate history in the tropical Andes
A new study that explores ancient temperatures and rainfall patterns in the tropical Andes of South America has revealed how 16,000 years of climate history in this part of the world was driven by carbon dioxide levels and ocean currents from global.....»»
A review of the Epichloë festucae antifungal protein Efe-AfpA
A research team has reviewed the mechanisms behind endophyte-mediated disease resistance in strong creeping red fescue (Festuca rubra subsp. rubra) and identified the antifungal protein Efe-AfpA produced by Epichloë festucae as a key factor against.....»»
U.S. vehicle inventory remains under 3 million in July
New-vehicle inventory levels temporarily crossed 3 million for first time in four years during CDK outage, then retreated back, Cox said......»»
Dutch survey study links air ventilation and other factors to work-from-home success
In a new survey study, Dutch employees who worked from home tended to report higher levels of productivity and less burnout if they were more satisfied with their home office setup. The study also linked more air ventilation in the home office to hig.....»»
Improving resolution and reducing noise in fluorescence microscopy with ensured fidelity
Fluorescence microscopy is a cornerstone of modern biological imaging, allowing scientists to study cells and their processes in real time. However, limitations in resolution and noise levels can hinder the clarity and detail of these images. Moreove.....»»
Nanomaterials may enhance plant tolerance to high soil salt levels
Soil salt concentrations above the optimal threshold for plant growth can threaten global food security by compromising agricultural productivity and crop quality. An analysis published in Physiologia Plantarum has examined the potential of nanomater.....»»
New York City"s fireworks display prompts temporary surge of air pollution
In 2023, roughly 60,000 firework shells exploded above Manhattan's East River as part of Macy's Fourth of July show. The resulting air pollutant levels were many times higher in the hours after the display than those seen when smoke from a Canadian w.....»»
Debby now a hurricane, threatens Florida, other parts of US southeast
Debby strengthened into a hurricane late Sunday as it bore down on Florida's Gulf Coast with potential for history-making levels of rain and major flooding, prompting evacuation orders......»»
Streetlights running all night makes leaves so tough that insects can"t eat them, threatening the food chain
Light pollution disrupts circadian rhythms and ecosystems worldwide—but for plants, dependent on light for photosynthesis, its effects could be profound. Now scientists writing in Frontiers in Plant Science have found that exposure to high levels o.....»»
