(Press-News.org) DENVER - A new research study highlights the significant health risks associated with dust storms, revealing an increase in emergency department (ED) visits for respiratory and cardiovascular conditions, as well as motor vehicle accidents, in three Southwestern U.S. states. The study, which was led at National Jewish Health was published this month in JAMA Network Open.
Researchers at National Jewish Health, Emory University and the University of Colorado analyzed over 33,500 ED visits across Arizona, California and Utah from 2005 to 2018. The findings indicate that dust storms are associated with a heightened risk of asthma, culture-negative pneumonia, chronic obstructive pulmonary disease, congestive heart failure, ischemic heart disease, cerebrovascular disease and motor vehicle accident admissions on the day of the storm or the days immediately following. The findings support the growing body of evidence that dust storms are dangerous, not only for drivers but also for people with chronic health conditions.
“Dust storms are expected to become more frequent due to climate change, so it’s crucial that we understand their immediate and long-term health impacts,” said James Crooks, PhD, associate professor at National Jewish Health and senior author on the study. “Our study provides important data for public health officials to develop strategies aimed at reducing dust storm-related health risks.”
Key findings of the study include:
A 6% increase in ED visits for asthma in the two days following a dust storm.
A 6% rise in ED visits for culture-negative pneumonia and congestive heart failure in the week following a storm.
A 13% increase in motor vehicle accidents on the day of a dust storm.
The study, which utilized National Weather Service storm reports and patient-level ED records, emphasizes the need for improved warning systems and public awareness initiatives to mitigate dust storm-related health impacts.
“Given the expected rise in dust storms, policymakers and health officials must take proactive measures to safeguard vulnerable populations,” said Dr. Crooks.
The research was supported by the National Institute of Environmental Health Sciences.

Stopping asthma in its tracks
2025-02-19
LA JOLLA, CA—Current asthma treatments don't work in all patients, and they don't provide long-term relief from potentially deadly asthma attacks.
Scientists at La Jolla Institute for Immunology (LJI) are advancing a new kind of therapy. According to a recent study published in the Journal of Allergy and Clinical Immunology, their approach holds promise for providing long-lasting relief for people with asthma—and it may be useful for dampening immune inflammation in general.
The researchers have developed two therapeutic ...
Chlorine plus UV light degrades toxins caused by harmful algae blooms
2025-02-19
Treatment plants use a combination of tools to keep toxins and contaminants out of drinking water.
Researchers with the University of Cincinnati examined two such tools in addressing a toxin produced by harmful algae blooms, which are becoming increasingly common in waters around the world.
Blue green algae can reproduce en masse in waters laden with nitrogen, phosphorus or other excess nutrients. These algae “blooms” also can form when water levels drop during droughts or when bottom sediments heavy with nutrients get churned up in a storm, said Minghao Kong, a doctoral graduate of UC’s ...
In Denmark, rural cat owners are neutering their cats and allowing them indoor access
2025-02-19
Cat owners in the Denmark countryside are increasingly managing their cats in the same way as urban cat owners, resulting in fewer unwanted kittens being born, according to a study published February 19, 2025, in the open-access journal PLOS One by Peter Sandøe from the University of Copenhagen, Denmark, and colleagues.
Populations of unowned domestic cats – whether unsocialized feral cats that have never lived with humans, or socialized cats that have strayed or been abandoned – are regarded as problematic in many countries. It is argued that they are a nuisance, that they transmit disease to humans, owned cats and ...

A miniature swimming robot inspired by marine flatworms
2025-02-19
Swimming robots play a crucial role in mapping pollution, studying aquatic ecosystems, and monitoring water quality in sensitive areas such as coral reefs or lake shores. However, many devices rely on noisy propellers, which can disturb or harm wildlife. The natural clutter in these environments – including plants, animals, and debris – also poses a challenge to robotic swimmers.
Now, researchers in the Soft Transducers Lab and the Unsteady flow diagnostics laboratory in EPFL’s School of Engineering, and at the Max Planck Institute for Intelligent Systems, have developed ...
Natural hydrogen: a sustainable energy source in mountain ranges
2025-02-19
The successful development of sustainable georesources for the energy transition is a key challenge for humankind in the 21st century. Hydrogen gas (H2) has great potential to replace current fossil fuels while simultaneously eliminating the associated emission of CO2 and other pollutants. However, a major obstacle is that H2 must be produced first. Current synthetic hydrogen production is at best based on renewable energies but it can also be polluting if fossil energy is used.
The solution may be found ...
Scientists identify a new cancer immunotherapy target: Dysfunctional B cells
2025-02-19
University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center scientists have discovered a novel subset of cancer-fighting immune cells that reside outside of their normal neighborhood – known as the tertiary lymphoid structure – where they become frustratingly dysfunctional when in close contact with tumors.
Described today in the journal Science Translational Medicine, the finding gives oncologists a new target for developing immunotherapies: double negative memory B cells, so-called because they are negative for two markers found on the surface of their more common brethren. They may also be a useful diagnostic ...
New Australian dinosaurs and the oldest megaraptorid fossils in the world
2025-02-19
Groundbreaking research published today in the Journal of Vertebrate Paleontology has unveiled a landmark discovery – fossils of the world’s oldest known megaraptorid and the first evidence of carcharodontosaurs in Australia. These finds rewrite the evolutionary history of theropod dinosaurs, uncovering a predator hierarchy unique to Cretaceous Australia.
The research, led by Museums Victoria Research Institute and Monash University PhD student Jake Kotevski, describes five theropod fossils discovered along Victoria’s coastline. The fossils were unearthed in the upper Strzelecki Group (Bunurong/Boonwurrung ...
