Mass Spectrometry 101

It's hard enough to weigh something as itty bitty as atoms or molecules. Factor in that they're careening by faster than Jeff Gordon on steroids, and you get an idea what scientists are up against. Using comet particles from NASA's Stardust mission as an example, this article explains how scientists measure atoms, and what kind of secrets they can uncover in the process.


Ancient porphyrins indicate far earlier date for photosynthesis

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.


Scouring Drinking Water for Disinfection Byproducts

Identification of toxic compounds in drinking water formed through disinfection reveals more than 3500 toxic, chlorinated species that can only be observed by the MagLab's high powered analytical instruments.


Life Recovered Rapidly at Impact Site of Dino-Killing Asteroid

MagLab geochemist Jeremy Owens analyzed ancient fossils for the multi-institutional study published today in Nature.


Prehistoric Findings Breathe New Life Into Climate Change Impacts

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


MagLab Geochemist Receives High Professional Honor

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


Ancient Rocks Provide Clues About Earth's Early History

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


In Ancient Oceans, Oxygen Loss Triggered Mass Extinction

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.


Tropical Soil Disturbance Could be Hidden Source of Carbon Dioxide

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.


Oxygen Depletion In Ancient Oceans Caused Major Mass Extinction

New study resolves a longstanding paleoclimate mystery.


Geochemists Solve Mystery of Earth's Vanishing Crust

Using a novel technique, researchers uncover secrets hidden deep below the surface of our planet.


International Study Discovers Ancient Meteoritic Impact Over Antarctica 430,000 years ago

Evidence indicates that this Antarctic airburst is the largest known airburst ever.


MagLab Researchers Find Oxygen Spike Coincided with Ancient Global Extinction

Researchers believe the ocean oxygenation occurred over a few tens of thousands of years, a very brief period in Earth’s geological history.


Student Makes Smashing Discovery About Meteorite

At research conducted at the MagLab, a young geochemist uncovers the surprisingly violent origins of a meteorite.


Pole Patrol

Keeping track of where on earth our poles are is practically a full-time job.


Meet Nur Gueneli

Paleobiogeochemist (no, that's not a typo) Nur Gueneli put some ancient dirt into our magnets to learn more about the Earth's earliest inhabitants.


Peat Soil

Looking for clues on climate change, a scientist digs up the dirt on peat from around the world.


Journey to Tibet

MagLab scientist Yang Wang joins an expedition to unearth the oldest woolly rhino fossils ever found.


Climate Change: Past and Future

Thanks to new funding, MagLab geochemist Jeremy Owens will learn more about ancient climate change, extinctions, oxygen levels, and new species to understand future climate impacts.
