Hurricanes Create Powerful Changes Deep in the Ocean, Study Reveals

With careful planning and a little luck, researchers found a surprising upside to hurricanes after a Category 4 storm disrupted their expedition off the coast of Mexico.

The team was able to sample the ocean right after the storm passed and found that the storms churn the ocean so powerfully and deeply — up to thousands of meters — that nutrient-rich, cold water is brought to the surface.

Students Awarded Prestigious NSF Graduate Research Fellowship

Two UC Merced graduate students and an alum from the School of Natural Sciences were recently awarded fellowships from the highly competitive National Science Foundation Graduate Research Fellowship Program.

This year, NSF awarded 1,000 GRFP fellowships compared to about 2,000 in previous years.

Study Indicates Human-caused Dust Events are Linked to Fallow Farmland

An average of more than 1 million acres of idled farmland a year is a significant contributor to a growing dust problem in California that has implications for millions of residents’ health and the state’s climate.

Dust is a Danger to Central Valley Health and Will Likely Get Worse, Researchers Find

People don't think about dust much until it's time to clean the house, but a new report by UC researchers could raise awareness of the growing threat of dust and dust storms.

Dust affects everything from cardiovascular and brain health to traffic collisions and agricultural yield. “Beyond the Haze: A UC Dust Report on the Causes, Impacts, and Future of Dust Storms in California” details the wide-ranging impacts of dust on health, public safety, the environment and California's economy.

For the First Time, All Avian Evolutionary Relationships Revealed Through Collaboration

Professor Emily Jane McTavish and colleagues at the Cornell Lab of Ornithology have mapped the evolution of every known bird species.

They created a complete evolutionary tree of bird species by combining data on 9,239 species published in nearly 300 studies between 1990 and 2024 and additional curated data on another 1,000 species. The resulting database can easily be shared and updated as additional studies are published.

Link Between Dementia and Air Pollution Drives Research Collaboration

California’s Central Valley, famous for producing much of the food Americans eat, is also infamous for its inferior air quality and its high rates of poverty, housing insecurity and at-risk workers.

Increasing epidemiological evidence has shown a correlation between long-term exposure to fine particulate matter (PM2.5) and the incidence of Alzheimer's disease and related dementias (ADRD).

Areas with severe PM2.5 pollution — including the Central Valley — are often inhabited by low-income residents who are disproportionately affected by these environmental hazards.

Research Team Focuses on the Next Generations of Scientists

The Biology Integration Institute (BII): The Institute for Symbiotic Interactions, Training and Education in the Face of a Changing Climate, or INSITE, stands out because it is supported by $12.5 million from the National Science Foundation, one of the largest NSF grants UC Merced has ever received.

UC Awards Support Tackling Big Questions in Health, Physics, Agriculture and Climate

Faculty members at UC Merced are taking the lead on four Multicampus Research Program Initiatives (MRPI), working with colleagues around the University of California system to address challenges around labor and agriculture, active matter, Indigenous health and fusion energy.

A Major Step Forward for UC Merced's Agricultural Experiment Station

The first four faculty members named to UC Merced's Agricultural Experiment Station look to make a big impact on farming in the San Joaquin Valley and beyond.

Study of Sugar Pines Reveals Urgent Issue in Protecting Forests from Climate Change

Sugar pines are the tallest pine species in the world, and they only grow along the West Coast of North America. They are a valued source of timber with cones as large as an adult’s forearm. But they face several problems that a new paper argues should be quickly addressed.

The sugar pine population has been declining because of changing fire patterns, drought, bark beetle mortality, a disease called white pine blister rust – and now the impacts of climate change.
