To understand the nascent stages of our roughly 4.6-billion-year-old solar system, researchers rely on cosmic time capsules, such as asteroids and meteorites. These materials capture the chemistry of the environments in which they formed, and one of the most pristine and primitive is a class...READ MORE
Michael Oskin was camping with his friends atop San Gorgonio Mountain, southern California’s highest peak, when the infamous Lander’s earthquake struck just before 5 a.m. on June 28, 1992. As aftershocks from the 7.3 magnitude earthquake rolled through the campsite, trees..READ MORE
On June 24, 2026, two devastating earthquakes struck the northern coast of Venezuela. The 7.2 magnitude foreshock was followed roughly 40 seconds later by a 7.5 magnitude mainshock. Known as a doublet, these earthquakes caused widespread damage and destruction in the country’s...READ MORE
Melting and breaking icebergs in the far-off, northeastern region of the Pacific Ocean can weaken a massive current system in the Atlantic Ocean, according to a University of California, Davis study published in Nature Communications. The Atlantic Meridional Overturning Circulation, or...READ MORE
Goabaone Jaqueline Ramatlapeng vividly remembers when she would go without water from domestic pipes for days. Growing up in Kopong, a small village in Botswana, Ramatlapeng, her family and those in surrounding villages faced a similar plight: water scarcity. And when the water did flow, it was salty...READ MORE

Paleobiologist Geerat Vermeij is enthralled with mollusks. Their shells line the surfaces and fill the cabinets and drawers in his office on the second floor of the Earth and Planetary Sciences Building at UC Davis. But Vermeij’s deep study of these organisms isn’t...READ MORE
In December 2025, Russian scientists published an analysis of a 67-million-year-old dinosaur fossil that was found in the Gobi Desert in 1979. The fossil specimen belonged to a small, two-legged dinosaur named Manipulonyx reshetovi, a part of the Alvarezsauridae family...READ MORE
Geology provides a language for understanding the Earth. Stories from the planet’s past are locked in the rocks and landscape. But others are hard to reveal, hidden in troves of data. No one knows this better than UC Davis Ph.D. alums and married...READ MORE
Professor Tessa Hill has been selected to join the 2026 cohort of the American Geophysical Union’s (AGU) Local Science Partners Program, a national initiative that strengthens the role of science in public decision-making. Chosen from a highly competitive applicant pool...READ MORE
Anchored in Cameroon’s Wouri Estuary, where rivers, tides, and ships converge, Claris Sunjo leans over the side of her boat. She’s twenty-four hours into collecting water from a tidal creek, a narrow channel connected to the Wouri Estuary system, asking a question scientists...READ MORE
