Molecular Fossils Shed Light on Ancient Life

Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. Research published Dec. 1 in Nature Communications combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.

What Shells Tell: Studying Abalone with Meghan Zulian

Shellfish, along with other marine organisms, are facing a crisis, one that affects the integrity of their shells. As carbon dioxide emissions increase in the atmosphere, so too does the amount of carbon dioxide absorbed by our oceans, leading to ocean acidification. Graduate student Meghan Zulian has devoted her doctoral studies to understanding how ocean acidification, and more broadly climate change, affects culturally, economically and ecologically important shellfish, including abalone

Deciphering the Black Box of Volcanoes: Kari Cooper Receives Norman L. Bowen Award

A fellow of both the American Association for the Advancement of Science and the Geological Society of America, geochemist Kari Cooper, a professor of earth and planetary sciences in the College of Letters and Science at UC Davis, won the American Geophysical Union’s Norman L. Bowen Award, which honors a mid-career or senior scientist for outstanding contributions to the fields of petrology, volcanology and geochemistry.

A Career Built in Deep Time: Geochemist and Paleoclimatologist Isabel Montañez Wins Arthur L. Day Medal

Over the course of her career, Distinguished Professor Isabel Montañez has created a research niche in the fields of geochemistry and paleoclimatology: applying an Earth systems science approach to recreate Earth from eons past. For her monumental work in the geology field, Montañez recently received the Geological Society of America’s Arthur L. Day Medal.

UC Davis Student Studying Ancient Microbial Life Named Goldwater Scholar

Caden Williams is among 413 college students nationwide selected from a pool of more than 5,000 applicants to receive the prestigious STEM scholarship, which was established by Congress in 1986 to honor the late U.S. Sen. Barry Goldwater. The award provides up to $7,500 for college expenses. This is the sixth consecutive year that a UC Davis student has been named a Goldwater Scholar.   

On Icy Enceladus, Expansion Cracks Let Inner Ocean Boil Out

In 2006, the Cassini spacecraft recorded geyser curtains shooting forth from “tiger stripe” fissures near the south pole of Saturn’s moon Enceladus — sometimes as much as 200 kilograms of water per second. A new study suggests how expanding ice during millennia-long cooling cycles could sometimes crack the moon’s icy shell and let its inner ocean out, providing a possible explanation for the geysers.

Ridgecrest Shows How Earthquakes Damage Earth’s Crust

In July 2019, a series of earthquakes — including two major shocks of magnitude 6.4 and 7.1 — struck near Ridgecrest, California, between Los Angeles and Las Vegas. For local residents, it was a violent interruption to the Fourth of July holiday. For seismologists, it was a rare opportunity to study how earthquakes damage the Earth’s crust.
