The added weight, electricity demand and aerodynamic drag of the sensors and computers used in autonomous vehicles are significant contributors to their lifetime energy use and greenhouse gas emissions, according to a new study.

When Hurricane Harvey struck Texas in August, industrial facilities in the state shut down, then reopened a few days later. In doing so, they produced nearly 2,000 tons of "excess emissions" -- air pollutants in addition to what was allowed as part of their normal operation.

Natural resources are continually extracted to produce goods that are used in the U.S. – often only briefly – before they are thrown into landfills, incinerators or the natural environment. This system of consumption and disposal results in the waste of precious resources and pollution that threatens our health, environment and global climate.

While serious violations like those in the Flint, Michigan, crisis are rare, ensuring reliable access to safe drinking water poses challenges for communities across the country, according to a recent study led by the University of California, Irvine.

Spraying weeds with chemicals has always been costly. Now it is costly and ineffective, with resistance to herbicides pervasive and demanding a new strategy to protect crops.

Washington State University researchers have found that salmon face a double whammy when they swim in the stormwater runoff of urban roadways.

First, as scientists learned a couple years ago, toxic pollution in the water can kill them. WSU researchers have now determined that fish that survive polluted stormwater are still at risk.

A Duke University-led study has found dangerously high levels of mercury and its more toxic chemical cousin, methylmercury, in soils, sediments and rivers near artisanal gold mines in the West African nation of Senegal.

A new study examined concentrations of polycyclic aromatic hydrocarbons (PAHs) before and after Hurricane Harvey in the Houston environmental justice neighborhood of Manchester.

Pine trees become temporarily sterile when exposed to ultraviolet radiation as intense as some scientists believe the Earth experienced 252 million years ago during the planet’s largest mass extinction, lending support to the theory that ozone depletion contributed to the crisis.

Study finds cleaner ship fuels will reduce childhood asthma by 3.6 percent globally
