Being able to accurately predict how the climate will change in the future is one of the most important quests of our lifetimes. A key to better prediction is the fundamental understanding of how particles in the atmosphere are connected to climate and climate change. One way to do that is to better understand the interactions between desert dust particles and radiation — from the sun and the Earth's surface.

Megalodon was the biggest shark in the world — 50 feet long or more — and one of the largest fish ever to exist. It roamed most of the world’s oceans from 23 million to 3.6 million years ago.

A new study by paleoecology Professor Sora Kim and colleagues shows the shark’s body temperature was considerably higher than previously thought and provides clues to the species’ demise.

UC Merced students Brianna Aguilar-Solis, Diane-Marie Brache-Smith, Sierra Lema and Sarif Morningstar, and alumni Diana Cruz Garcia and Anna Maria Calderon were awarded fellowships from the National Science Foundation (NSF) Graduate Research Fellowship Program (GRFP).

The five-year fellowship provides three years of financial support inclusive of an annual stipend of $37,000, as well as access to opportunities for professional development.

Chemistry Professor Aurora Pribram-Jones is looking for undergrads to help her get the lead out — out of drinking-water pipes.

Professor Sora Kim has received a CAREER award for her project that bridges concepts between modern and ancient marine ecosystems by integrating geochemical and modeling approaches with paleobiology.

Kim is the 34th researcher from UC Merced to earn a CAREER award from the National Science Foundation (NSF).

Aneelman Brar wants to reduce carbon dioxide in the atmosphere.

The Chemistry and Chemical Biology Ph.D. student’s three-minute talk entitled “From Pollutant to Fuel and New Products: Recycling Carbon Dioxide” earned her bragging rights as UC Merced's Grad Slam champion and a $5,000 prize, plus the opportunity to represent the campus at the UC systemwide finals on May 5.

UC Merced continues to be recognized nationally, with some programs leaping forward, according to U.S. News & World Report’s 2023-2024 edition of Best Graduate Schools released on April 25.

At UC Merced, mercury is a regional challenge that student and faculty researchers have been tackling for several years. Mercury was used to extract gold during the Gold Rush in California, and the element was also mined at the New Almaden site, at one time the second-largest mercury mine in the world near today’s Silicon Valley.

Carbon dioxide (CO₂) is a greenhouse gas that is contributing to irreversible climate change. Scientists know how to capture CO₂, and they know how to transform it into useful molecules and materials.

But that transformation is neither energy nor cost-effective.

Through a prestigious grant from the Department of Energy (DOE), a diverse group of scientists, including a chemist from UC Merced, plan to address that problem by coupling two chemistries which are known to work independently, but don't work well together.

For the first time, UC Merced faculty members from each of the campus’s three schools have been chosen as principal investigators on some of the 21 exciting new projects that are being funded through UC’s Multicampus Research Programs and Initiatives (MRPI).

In addition, UC Merced researchers are collaborating on 10 of the other projects.
