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.
