Not such small things: microplastics in our streams
UC Riverside scientists are taking a modern approach to studying a murky subject — the quantity, quality, and sources of microplastics in Los Angeles County’s urban streams.
Methane from megafires: more spew than we knew
Using a new detection method, UC Riverside scientists found a massive amount of methane, a super-potent greenhouse gas, coming from wildfires — a source not currently being accounted for by state air quality managers.
Manganese in Central Valley water threatens fetuses and children
Water in California’s Central Valley contains enough manganese to cause cognitive disabilities and motor control issues in children, and Parkinson’s-like symptoms in adults.
Fungi and bacteria are binging on burned soil
UC Riverside researchers have identified tiny organisms that not only survive but thrive during the first year after a wildfire. The findings could help bring land back to life after fires that are increasing in both size and severity.
Soil tainted by air pollution expels carbon
New UC Riverside research suggests nitrogen released by gas-powered machines causes dry soil to let go of carbon and release it back into the atmosphere, where it can contribute to climate change.
Prof pours cold water on coffee pod controversy
New research from the University of Quebec declares coffee pods are “better for the planet than filtered brew.” Here to weigh in on the matter is UCR's Andrew Gray, who studies the movement of plastic pollutants through the environment.
Post-lockdown auto emissions can’t hide in the grass
University of California scientists have a new way to demonstrate which neighborhoods are most affected by air pollution from vehicle emissions. Their technique could help ensure people most affected by pollution will benefit from efforts to reduce it.
Why the Salton Sea is turning into toxic dust
The Salton Sea, California’s most polluted inland lake, has lost a third of its water in the last 25 years. New research has determined a decline in Colorado River flow is the reason for that shrinking.
Who’s responsible for roadside rubbish?
New UC Riverside research reveals that items in litter typically originate less than two miles from where they’re found — and unless humans remove them, most of these items will never leave the environment.
Wildfires can cause dangerous debris flows
Wildfires don’t stop being dangerous after the flames go out. Even one modest rainfall after a fire can cause a deadly landslide, according to new UC Riverside research. “When fire moves through a watershed, it creates waxy seals that don’t allow water to penetrate the soil anymore,” explained environmental science...
Climate change will decimate Palm Springs, Coachella Valley tourism
A new UC Riverside study finds that climate change will have a devastating effect on the greater Palm Springs area’s dominant industry — tourism. Thousands known as “snowbirds” flock to the region annually from elsewhere in the country to escape freezing winters. However, due to climate change, the number of...
Shrub encroachment on grasslands can increase groundwater recharge
Vegetation changes can outweigh climate change in rangeland water budgets
New commuter concern: cancerous chemical in car seats
A new UC Riverside study concludes the longer your commute, the more you're exposed to a chemical flame retardant that is a known carcinogen, phased out of furniture use because it required a Proposition 65 warning label in California.
Agricultural area residents in danger of inhaling toxic aerosols
Excess selenium from fertilizers and other natural sources can create air pollution that could lead to lung cancer, asthma, and Type 2 diabetes, according to new UC Riverside research.
Testing chemicals for birth defects using stem cells, not mice
UC Riverside researchers are helping the U.S. Environmental Protection Agency eliminate animal testing
Climate change: a dirt-y business
Groundwater is essential for growing crops, but new research shows climate change is making it harder for soil to absorb rainfall. While the idea that soil particles rearrange themselves in response to environmental conditions is not new, scientists once thought these shifts in the ground happened slowly. Not anymore. A...
Climate-induced soil changes may cause more erosion and flash flooding
More intensive water cycle could have impact on biodiversity, human health, and water and food security
