Space dust as Earth's sun shield

On a cold winter day, the warmth of the sun is welcome. Yet as humanity emits more and more greenhouse gases, the Earth's atmosphere traps more and more of the sun's energy and steadily increases the Earth's temperature. ...

Tracking ocean microplastics from space

New information about an emerging technique that could track microplastics from space has been uncovered by researchers at the University of Michigan. It turns out that satellites are best at spotting soapy or oily residue, ...

Unearthing the impact of moisture on soil carbon processes

The ground below your feet contains some 2,500 gigatons of carbon, approximately three times the amount of carbon held in our atmosphere and four times more than is stored in every living thing—trees, ants, whales, and ...

Artificial sweetener as a wastewater tracer

Acesulfame is a sweetener in sugar-free drinks and foods. As it cannot be metabolized in the human body, the sweetener ends up in wastewater after consumption and remains largely intact even in sewage treatment plants. A ...

A new measure of roughness could advance earthquake geophysics

When two rocks interact with each other in a fault zone, the roughness of their surfaces could influence the outcome, including when they cause earthquakes. Still, the underlying mechanics of this relationship remain unclear.

Applications for a newly developed risk and resilience tool

By the mid-century, many parts of the United States will experience longer summers with more extreme heat events. While swelteringly hot days are uncomfortable, they can become dangerous for some households, particularly ...

Air pollution linked with blood pressure in London teens

In a new analysis involving adolescents living in London, exposure to higher levels of the pollutant nitrogen dioxide was associated with lower systolic blood pressure, while exposure to higher levels of particulate matter ...

Improving wildfire predictions with soil science

Severe wildfires have become annual events in the United States. The years 2020 and 2021 were the worst in wildfire history in California. Other states—and countries—are at risk as well. Climate change is making wildfires ...

Sounding the alarm on microplastic pollution

There are four basic ingredients in beer: grain, hops, yeast and water. The water often introduces a fifth, which passes unfiltered into a typical pilsner.
