After wildfires, do microbes exhale potent greenhouse gas?

Laughing gas is no laughing matter — nitrous oxide is a greenhouse gas with 300 times the warming potential of carbon dioxide. Scientists are racing to learn whether microorganisms send more of it into the atmosphere after wildfires.

Could more of Earth’s surface host life?

Of all known planets, Earth is as friendly to life as any planet could possibly be — or is it? If Jupiter’s orbit changes, a new study shows Earth could be more hospitable than it is today. When a planet has a perfectly circular orbit around its star, the distance...

Sleeping giant could end deep ocean life 

A previously overlooked factor — the position of continents — helps fill Earth’s oceans with life-supporting oxygen. Continental movement could ultimately have the opposite effect, killing most deep ocean creatures. “Continental drift seems so slow, like nothing drastic could come from it, but when the ocean is primed, even a...

Drought increases microbe-laden dust landing in Sierras

Dust from all over the world is landing in the Sierra Nevada mountains carrying microbes that are toxic to both plants and humans. Research from UC Riverside shows higher concentrations of the dust are landing at lower elevations, where people are more likely to be hiking.

The chemical controlling life and death in hair follicles

A single chemical is key to controlling when hair follicle cells divide, and when they die. This discovery could not only treat baldness, but ultimately speed wound healing because follicles are a source of stem cells.

Why Jupiter doesn’t have rings like Saturn

Because it’s bigger, Jupiter ought to have larger, more spectacular rings than Saturn has. But new UC Riverside research shows Jupiter’s massive moons prevent that vision from lighting up the night sky.

Ancient microbes may help us find extraterrestrial life forms

Using light-capturing proteins in living microbes, UC Riverside scientists helped reconstruct what life was like for some of Earth’s earliest organisms. These efforts could help us one day recognize signs of life on other planets.
