Green space exposure, mental health and the nasal microbiome explored
Green space exposure, mental health and the nasal microbiome explored Gaby Clark Scientific Editor Robert Egan Associate Editor Plenty of studies have linked exposure to nature to a wide variety of health benefits, from improved cognitive function to lower blood pressure to better mental health. Other research has found connections between the human microbiome and time spent outside. But an overlooked, understudied player in that connection is the assemblage of microbes found in the nose, or...
Probabilistic dietary exposure modeling and health risk assessment of heavy metals via the fodder-cattle-human continuum in Bangladesh
Dietary exposure to heavy metals (HMs) via animal-source foods is a critical environmental health pathway. In rapidly industrializing Bangladesh, contamination of the bovine food chain from agricultural feeds and industrial emissions poses an unquantified public health burden. This study evaluated exposure pathways, spatial distribution, mass-transfer dynamics, and health risks of six HMs (Cr, Cu, Cd, Pb, As, and Hg) across the fodder-cattle-human continuum.
Florida man arrested after allegedly trying to sell stolen radiological device that could have made people ill on Facebook Marketplace
Florida man arrested after allegedly trying to sell stolen radiological device that could have made people ill on Facebook Marketplace Improper handling or damage to the device could have caused severe health complications due to radiation exposure - Bookmark A Florida man was arrested after investigators tracked a stolen radiological device to his home using a Facebook Marketplace listing, authorities said. The suspect, 24-year-old Marco Antonio Benitez Jr., was taken into custody following...
Smoke engulfed their cities. Did it make their children sick?
Mothers fear children's chronic illnesses are linked to bushfire smoke during pregnancy Sun 31 May 2026 at 5:16am Six years after Black Summer bushfires, parents and doctors face an unsettling question: What does bushfire smoke do to babies in the womb? This story is a collaboration between the ABC's climate team and climate media organisation Grist. They never thought the fires would reach them.
Decoding Chromosome Radiosensitivity in G0-Phase PBMCs: Genomic Determinants, Age, Sex effects, and Implications in Radiation Dose Assessment
Low-dose ionizing radiation from natural and anthropogenic sources is typically not of significant concern under normal conditions. However, in case of radiological incidents, it becomes an important environmental hazard, raising concern for public health and necessitating reliable biological indicators of exposure. Chromosomal aberrations are most reliable markers of radiation exposure and are more or less universally assessed in metaphases.
What Causes COVID-19 Fear? General Drivers of Fear During a Health Crisis
arXiv:2508.20146v3 Announce Type: replace Abstract: The COVID-19 pandemic triggered not only a global health crisis but also an infodemic, where exposure to heterogeneous information sources influenced public emotional responses. In this work, we investigate the determinants of self-reported fear of infection using data from the Delphi US CTIS survey. In particular, we analyze how demographic variables, epidemiological conditions, and exposure to different information sources shape fear levels.
Copper thieves are more brazen and taking exceptional risks, demolition experts say
Copper theft on demolition sites now commonplace and costing thousands, contractors say Tue 2 Jun 2026 at 4:49pm In short: Copper theft from demolition sites is now the norm, Perth demolition contractor Steve King says. Thieves appear to be gambling with their health and safety, risking electrocution, falls and asbestos exposure to get the scrap metal. Legislation introduced in 2020 to monitor the sale of scrap copper does not appear to have had much effect on theft.
Wildfires are reversing America's progress on ozone pollution
Wildfires are reversing America's progress on ozone pollution Lisa Lock Scientific Editor Andrew Zinin Lead Editor For decades, the United States made steady progress in reducing surface ozone pollution, the main ingredient in smog. But that progress—made as vehicles, industries, and power sources became cleaner—is increasingly being overshadowed by a different and growing source of ozone pollution: wildfires. Our team of atmospheric and wildfire scientists analyzed wildfires' contribution...
Even 'safe' air pollution levels can carry health risks
Even 'safe' air pollution levels can carry health risks Gaby Clark Scientific Editor Robert Egan Associate Editor Air pollution does not have to exceed federal limits to potentially harm human health, according to a new published study from the University of Mississippi. In a review of decades of air pollution studies, Ole Miss researchers found evidence that exposure to PM2.5—microscopic particles produced by traffic, industry and smoke—may harm heart health even at concentrations below the...
How sargassum affects air quality, beach environments and exposure risks for families
As another heavy sargassum season unfolds, many beachgoers are asking the same question: Is it safe to be near it? A recent University of Miami study offers an evidence-based answer, particularly for children. Overall risks are low, but not zero.
