New sensor detects low air humidity

Measuring air humidity is important in many areas. However, conventional sensors in hygrometers have so far not been able to determine a very low water vapor content. Physicists at the University of Duisburg-Essen (UDE) and ...

Effectively removing carbon dioxide from the atmosphere

Researchers at the Paul Scherrer Institute PSI and ETH Zurich have investigated the extent to which direct capture of carbon dioxide (CO2) from the ambient air can help to effectively remove greenhouse gasses from the atmosphere. ...

Addressing inequity in air quality

Air quality varies greatly within regions and cities around the world, and exposure to air pollution can have severe health impacts. In the U.S., people of color are disproportionately exposed to poor air quality. A cover ...

How grasslands respond to climate change

"Based on field experiments with increased carbon dioxide concentration, artificial warming, and modified water supply, scientists understand quite well how future climate change will affect grassland vegetation. Such knowledge ...

Experiments show dogs can 'smell' radiated heat

A combined team of researchers from Lund University in Sweden and Eötvös Loránd University in Hungary has found evidence that dogs are able to "smell" radiated heat. In their paper published in the journal Scientific Reports, ...
