Scientists find that black carbon is a good tracer to separate cooking organic aerosol from traffic-related organic aerosol.
Heavily polluted areas have a higher rate of angioplasty procedures to treat blocked arteries than areas with clean air, according to research to be presented at ESC Congress 2019 together with the World Congress of Cardiology. Procedures are even more common in winter, the most polluted time of year.
Many wild southern sea otters in California are infected with the parasite Toxoplasma gondii, yet the infection is fatal for only a fraction of sea otters, which has long puzzled the scientific community. A study from the University of California, Davis, identifies the parasite's specific strains that are killing southern sea otters, tracing them back to a bobcat and feral domestic cats from nearby watersheds.
Just when international fears of contracting Zika began to fade in 2017, an undetected outbreak was peaking in Cuba -- a mere 300 miles off the coast of Miami. A team of scientists at Scripps Research, working in concert with several other organizations, uncovered the hidden outbreak by overlaying air-travel patterns with genomic sequencing of virus samples from infected travelers. The discovery is featured on the cover of the Aug. 22, 2019 issue of Cell.
An epidemic of chronic kidney disease that has killed tens of thousands of agricultural workers worldwide, is just one of many ailments poised to strike as a result of climate change, according to researchers at the University of Colorado Anschutz Medical Campus
More than 200,000 people are employed as truck drivers in Australia and while their role in transporting goods across its wide brown land is critical, they are among the nation's most unhealthy. Dr Marguerite Sendall from QUT's School of Public Health and Social Work says driving a truck and being healthy is possible but drivers need a little help from the workplace to find the time and motivation.
A new international study has found that air pollution is linked to increased cardiovascular and respiratory death rates. The study is the largest of its kind to investigate the short-term impacts of air pollution on death, conducted over a 30-year period. The study analyzed data on air pollution and mortality in 24 countries and regions.
For the first time scientists have been able to reconstruct the chemical composition of rainwater from 300-million-year-old minerals, allowing them to unpick some of the history of Brittany and Western France since the rain fell in the late Carboniferous period, just before the time of the dinosaurs. The results point to the area being mountainous and originally located close to the Equator. This work is presented at the Goldschmidt Geochemistry congress in Barcelona.
Based on analysis of large population data sets from both the United States and Denmark, a new study found poor air quality associated with increased rates of bipolar disorder and major depression in both countries.
New research shows that visitors to urban parks use happier words and express less negativity on Twitter than before their visit -- and that their elevated mood lasts for up to four hours. The effect is so strong that it's equivalent to the mood spike on Christmas, the happiest day each year on Twitter. With increasing urbanization and mood disorders, this research may have powerful implications for public health and urban planning.
