Uncovering diversity in an invisible ocean world

Plankton are vital to life on Earth—they absorb carbon dioxide, generate nearly half of the oxygen we breathe, break down waste, and are a cornerstone of the marine food chain. Now, new research indicates the diminutive ...

Algae blooms create their own favorable conditions, study finds

Fertilizers are known to promote the growth of toxic cyanobacterial blooms in freshwater and oceans worldwide, but a new multi-institution study shows the aquatic microbes themselves can drive nitrogen and phosphorus cycling ...

Hydrogen powers important nitrogen-transforming bacteria

Nitrite-oxidizing bacteria are key players in the natural nitrogen cycle on Earth and in biological wastewater treatment plants. For decades, these specialist bacteria were thought to depend on nitrite as their source of ...

Study reveals dynamics of microbes and nitrate

Human tampering with global carbon balances has received massive public attention because of its effects on global warming, but we pay less attention to another set of chemical processes we are similarly disrupting: human ...

Dangerous nitrogen pollution could be halved

The most important fertilizer for producing food is, at the same time, one of the most important risks for human health: nitrogen. Chemical compounds containing reactive nitrogen are major drivers of air and water pollution ...
