UCalgary ecotoxicology expert Ben Barst contributes to study of marine food’s impact on predators.

Fragrances and lotions don't just change the way people smell, they actively alter the indoor air chemistry around the wearer, disrupting a critical natural process the body uses to protect itself from pollution, according to an international research team that includes scientists from Penn State.

The 120-mile Tijuana River flows from Baja California into the United States and discharges millions of gallons of wastewater — including sewage, industrial waste and runoff — into the Pacific Ocean every day, making it the dominant source of coastal pollution in the region.

How sensitively does organic carbon stored in soils react to changes in temperature and humidity?

Separating crude oil into products such as gasoline, diesel, and heating oil is an energy-intensive process that accounts for about 6 percent of the world’s CO2 emissions.

Global warming will likely hinder our future ability to control ground-level ozone, a harmful air pollutant that is a primary component of smog, according to a new MIT study.

A new international research initiative will measure hydrogen emissions from operating infrastructure in North America and Europe, filling a gap where little empirical data exist today.

Today’s carbon capture systems suffer a tradeoff between efficient capture and release, but a new approach developed at MIT can boost overall efficiency.

The ocean has absorbed about 30% of carbon dioxide emissions from human activities since the Industrial Revolution, significantly slowing the pace of climate change.

Warming in the Arctic is intensifying methane emissions, contributing to a vicious feedback loop that could accelerate climate change even more, according to a new study published May 7 in Nature.
