Almost every chemist has used mass spectrometry at some point at some point in his or her scientific life, but did you know about all of its cool applications in the study of proteomics? This field has been growing by leaps and bounds as more and more biologists discover the power of mass spectrometry. Check out Nature Methods’ special Focus issue on mass spectrometry in proteomics applications.

Nitrogen and sulphur compounds contribute to declining ocean pH.

Carbon dioxide (CO2) isn’t the only atmospheric pollutant making the oceans more acidic and threatening the health of coral reefs and plankton. New research suggests that nitrogen and sulphur released into the air by human activities may be driving down the pH more than expected in some coastal waters.
