Some manmade chemicals feature bonds so strong they could last forever. And that's a life-threatening problem.

Using the world's most accurate molecular scale, a former astronaut wanna-be is studying Titan's hazy atmosphere, which resembles the ancient chemistry that once surrounded our own planet.

New study resolves a longstanding paleoclimate mystery.

Using powerful instruments at the National MagLab, scientists discovered that older dissolved organics from deforested areas were more energy-rich, and potentially more harmful to the planet.

In findings that could shed light on current climate changes, researchers find conclusive evidence linking rising sea levels and lowering oxygen levels to decimation of marine species.

MagLab data provide compelling evidence that extensive oxygenation took place in the ocean millions of years before the atmosphere’s “Great Oxidation Event.”

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.

Volcanic activity, declining ocean oxygen triggered mass extinction of ancient marine organisms.
