In high enough concentrations, milkweed can kill a horse, or a human. To be able to eat this plant, monarchs evolved a set of unusual cellular mutations. New UC Riverside research shows the animals that prey on monarchs also evolved these same mutations.

A team of researchers led by UC Riverside has demonstrated for the first time one way that a small molecule turns a single cell into something as large as a tree. For half a century, scientists have known that all plants depend on this molecule, auxin, to grow. Until now...

Bumblebees pollinate many of our favorite foods, but their own diet is being upset by climate change, according to a new UC Riverside study.

Nobody is currently taking continuous, routine measurements of the particles suspended in America’s air, called aerosols. That is set to change as a new, nationwide monitoring network launches with a site in Riverside, California.

Bombardment of Earth’s surface by asteroids six or more miles long likely delayed the accumulation of oxygen in Earth’s atmosphere. This, in turn, likely delayed the development of complex life on the planet, according to new research that included UC Riverside scientists.

Paleontologist Nigel Hughes has earned one of the highest honors in his field, an achievement made even more remarkable because last year’s winner was another UCR paleontologist — Mary Droser, his wife.

Scientists have figured out how plants respond to light and can flip this genetic switch to encourage food growth - even in the dark. The discovery could help increase food supply for an expanding population with shrinking opportunities for farming.

New UC Riverside research shows groundwater takes an average of three years to recover from drought — if it ever recovers at all. In the largest study of its kind, scientists found that this recovery time only applies to aquifers that aren’t touched by human activity, and the recovery time...

When the world’s most powerful telescope launches into space this year, scientists will learn whether Earth-sized planets in our ‘solar neighborhood’ have a key prerequisite for life — an atmosphere.

Seeds that would otherwise lie dormant will spring to life with the aid of a new chemical discovered by a UC Riverside-led team.

The future of vaccines may look more like eating a salad than getting a shot in the arm. UC Riverside scientists are studying whether they can turn edible plants like lettuce into mRNA vaccine factories.

In less time than it takes to read this sentence, hummingbirds can catch a whiff of potential trouble. That’s the result of new UC Riverside research showing, contrary to popular belief, the tiny birds do have an active sense of smell.

After more than a year of lockdown, school is back in session. But many people are wondering whether it should be. Here, UC Riverside experts in viruses, medical policy and education share their thoughts about whether in-person learning at this moment in time is an A+ idea, and offer ideas...

There are finally efforts under way to improve the environmental health disaster that is the Salton Sea — California’s largest and most polluted lake. However, a group of UC Riverside scientists, engineers, medical experts, and economists has published a new report warning that without science, these efforts may not succeed.

A new UC Riverside study shows that a type of insecticide made for commercial plant nurseries is harmful to a typical bee even when applied well below the label rate.

A team of scientists has developed an approach to disposing wastewater that reduces the danger of triggering an earthquake.

UC Riverside is leading a new, $1.26 million project to bring calculus classes to life for students who are underrepresented in science, technology, engineering, and math subjects.

A team of scientists led by UC Riverside has devised a more accurate way to predict the effects of climate change on plants and animals — and whether some will survive at all.

A new UC Riverside study finds geckos are fierce hunters whether or not their tails are attached to their bodies.

UC Riverside scientists are hoping the RNA of an obscure infection can one day be used like a Trojan horse to deliver life-saving treatments to citrus trees.
