Iron is a micronutrient indispensable for life, enabling processes such as respiration, photosynthesis, and DNA synthesis. 

Microbes in the environment, not fossil fuels, have been driving the recent surge in methane emissions globally, according to a new, detailed analysis published Oct 21 in the Proceedings of the National Academy of Sciences by CU Boulder researchers and collaborators.

The combined impact of so-called ‘forever chemicals’ is more harmful to the environment than single chemicals in isolation, a new study shows.

A new Curtin University study investigating the complex evolution of two iconic Western Australian landmarks, has traced their transformation over thousands of years and offers a glimpse into their future.

Changing precipitation patterns in the Neotropics, one of Earth’s most biodiverse regions, could threaten two-thirds of the area’s bird species by the year 2100 if climate change goes unchecked, according to new research led by the University of Illinois Urbana-Champaign and George Mason University.

Polar bears in some parts of the high Arctic are developing ice buildup and related injuries to their feet, apparently due to changing sea ice conditions in a warming Arctic.

A firm understanding of the photovoltaic effect, by which light can be converted into useful electrical energy, lies at the core of solar cell design and development.
