Development of a rugged continuous electronic monitoring device to detect soil fertility in farm fields could be a boon to agriculture in the United States and the United Kingdom (UK).

Producing a liter of milk in California emits less greenhouse gas and uses less land and water than it did in 1964, according to a recent study from researchers at the University of California, Davis.

Ecologists in England and Scotland, collaborating with ecologists Christopher Sutherland and Joseph Drake at the University of Massachusetts Amherst, report this week on a new method of identifying an “entire community of mammals” – including elusive and endangered species that are otherwise difficult to monitor – by collecting DNA from river water.

The polar ice caps are melting six times faster than in the 1990s, according to the most complete analysis to date.

Heat stress from extreme heat and humidity will annually affect areas now home to 1.2 billion people by 2100, assuming current greenhouse gas emissions, according to a Rutgers study.

As oceans absorb more carbon dioxide, they are becoming increasingly acidic and shifting the delicate balance that supports marine life. 

New research from The University of Texas at Austin has explained an important mystery about natural gas hydrate formations and, in doing so, advanced scientists’ understanding of how gas hydrates could contribute to climate change and energy security.

Excess electrons could help break the strong chemical bonds in products that contaminate water supplies.

Though they may look smooth, standard silicon wafers used for solar cells feature tiny pyramidal structures about two micrometres high.

A new Simon Fraser University-led study looking at the effects that glacier retreat will have on western North American Pacific salmon predicts that while some salmon populations may struggle, others may benefit.
