Researchers examine ancient microbes to find life beyond earth

Researchers have reproduced what life was like for some of the oldest species on Earth using light-capturing proteins found in living microorganisms. These initiatives may enable everyone to spot life in distant worlds, whose atmospheres mirror the pre-oxygen planet more closely.

Study finds higher levels of air pollutants in regions near oil and gas wells

In a 14-year analysis of air quality across California, Stanford researchers observed higher levels of air pollutants within 2.5 miles of oil and gas wells, likely worsening negative health outcomes for nearby residents.

Long-term exposure to low concentrations of air pollution may increase mortality risk

Exposure to low concentrations of air pollution, even at levels permitted under federal regulations, may be causing tens of thousands of early deaths each year among elderly people and other vulnerable groups in the U.S., according to a large national study from Harvard T.H. Chan School of Public Health.

High ozone concentrations decrease crop yield in maize

Although stratospheric ozone protects us by filtering out the sun's ultraviolet radiation, tropospheric ozone is a harmful pollutant. A new study has shown that ozone in the lower layers of the atmosphere decreases crop yields in maize and changes the types of chemicals that are found inside the leaves.

Traffic reductions caused by COVID-19 shutdowns improved air quality in some states

Dramatic decreases in traffic caused by COVID-19 shutdowns improved air quality in car-dependent states but didn't offset additional forms of pollution in other parts of the country.

Researchers document effect of air pollution on people experiencing homelessness

When air quality worsens, either from the smoke and ozone of summer or the inversion of winter, most of us stay indoors. But for individuals experiencing homelessness, that's not always an option.

Researchers compare air pollution in urban and suburban areas of China

For the first time, researchers have compared air pollution in urban and suburban areas across all of China. Using data from the China National Environmental Monitoring Center (CNEMC), the researchers found that one air pollutant, called particulate matter (PM2.5), maybe overestimated in winter, while another pollutant, called ozone (O3), is significantly underestimated.

Urban air pollution may make COVID-19 more severe for some

In a recent study, researchers at Emory University found that long-term exposure to urban air pollution may have made COVID-19 more deadly.

Energy-efficient, climate-friendly cooling could lower greenhouse gas emissions

A new IIASA-led study shows that coordinated international action on energy-efficient, climate-friendly cooling could avoid as much as 600 billion tonnes CO2 equivalent of greenhouse gas emissions in this century.

Climate change is a risk accelerator for several aspects of economy and society

It could be worth up to 8% of GDP per capita, exacerbate the differences between north and south, between society's rich and poor, as well as affect a number of Italy's strategic sectors: climate change is a risk accelerator for many aspects of both the economy and society.
