Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in older adults, according to new research.

An international team of scientists, led by the University of Leeds, has quantified the relationship between natural sources of particles in the atmosphere and climate change.

Their study, published today in Nature Geoscience, shows that the cooling effect of natural atmospheric particles is greater during warmer years and could therefore slightly reduce the amount that temperatures rise as a result of climate change.  

Worldwide, the United States is one of the biggest greenhouse gas emitters. The Obama administration began efforts to drop those numbers by increasing vehicle fuel economy standards in 2011 and with its Clean Power Plan proposals in 2015.

Endocrine disrupting chemicals (EDCs) are associated with a number of possible health issues.

EDCs are mostly produced by humans. They’re found in all sorts of things from pesticides and herbicides, and from cropland and livestock waste effluents and municipal and industrial waste to personal care products.

A new study of methane emissions from livestock in the United States — led by a researcher in Penn State's College of Agricultural Sciences — has challenged previous top-down estimates.

EarthSense Systems – a joint venture between the University of Leicester and aerial mapping company BlueSky - has published MappAir® – the first ever high resolution nationwide map of air pollution.

High in the snowfields atop the Rocky Mountains in Colorado, things are not as pristine as they used to be. Dust from the desert Southwest is sailing into the Rockies in increasing quantities and settling onto the snow that covers the peaks, often streaking the white surface with shades of red and brown.

Global warming is likely to speed up as the Earth becomes increasingly more sensitive to atmospheric CO? concentrations, scientists from the University of Reading have warned.

In a new study, published this week in the prestigious journal PNAS, the scientists explain that the influence of increasing levels of atmospheric CO2 on global warming will become more severe over time because the patterns of warming of the Earth’s surface will lead to reduced cloud cover in some sensitive regions and less heat being able to escape into space.

A new study from UBC’s Okanagan campus has found that BMAA—a toxin linked to several neurodegenerative diseases—is present in high concentrations during cyanobacteria blooms in Lake Winnipeg.

At Thanksgiving, many Americans look forward to eating roast turkey, pumpkin pie, and tangy red cranberries. To feed that appetite, cranberry farming is big business. In Massachusetts, cranberries are the most valuable food crop. The commonwealth’s growers provide one-fourth of the U.S. cranberry supply.
