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.

To the untrained eye, Jeremy Gustafson’s 1,600-acre farm looks like all the others spread out across Iowa. Gazing at his conventional corn and soybean fields during a visit in June, I was hard-pressed to say where his neighbor’s tightly planted row crops ended and Gustafson’s began.

Researchers have determined how female grizzly bears keep their cubs safe while crossing the Trans-Canada Highway.
