Water samples collected from the heart of Africa contain clues about carbon cycling worldwide.

Molecular fossils of chlorophyll (called porphyrins) more than 1.1 billion years old find suggest that photosynthesis began 600 million years earlier than previously established.

Vincent Salters joins the elite ranks of American Geophysical Union fellows.

Protein oxidative damage is a common occurrence in a number of diseases, including cancer, neurodegenerative, and cardiovascular disease. Yet, little is known about its contribution to these illnesses. We developed a new technique, utilizing an infrared laser in combination with a mass spectrometer, to selectively identify sites of oxidation in complex protein mixtures. This sensitive and rapid platform may outperform current techniques and thus shed light on the involvement of oxidative damage in each of these diseases.

Members of a sprawling science team piece together the puzzle of biochar, a promising tool in the fight against global warming.

Dylan Murray wants to sabotage processes that can lead to neurodegenerative disease.

From nanorockets to nanocages, good science can come in tiny packages — all with the aim of solving really big problems.

A lot of the research conducted in powerful magnets ends up having a powerful effect on our day-to-day lives.

We open a can of worms to learn how pheromones  help invertebrates regulate population.
