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.
Remembering ‘isotope queen’ Marilyn Fogel, pioneering scientist, beloved mentor
Marilyn Fogel, endowed geoecology professor at UC Riverside, died on May 11 in Mariposa, Calif. She was 69. She pioneered the use of isotopes to understand the life history of organisms, both modern and ancient. In so doing, she helped develop biogeochemistry as a new field of science and earned...
Lesser known ozone layer’s outsized role in planet warming
New UC Riverside-led research has identified a lesser-known form of ozone playing a big role in heating the Southern Ocean — one of Earth’s main cooling systems.
Why Venus rotates, slowly, despite sun’s powerful grip
If not for the soupy, fast-moving atmosphere on Venus, Earth’s sister planet would likely not rotate. Instead, Venus would be locked in place, always facing the sun the way the same side of the moon always faces Earth. The gravity of a large object in space can keep a smaller...
Extraterrestrial objects likely delayed complex life on Earth
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.
Meet UCR’s paleontology power pair
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.
Investigating the potential for life around the galaxy’s smallest stars
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.
UCR joins forces with NASA on missions to Venus
By joining NASA on their newly announced missions, UC Riverside is hoping to learn how Venus went from pleasant, Earth-like planet to blistering wasteland.
Project illuminates where giant exoplanets reside
Astronomers have long wondered whether the configuration of planets in our solar system is common elsewhere in the universe. New results from the longest-running survey of exoplanets helps answer this question.
Study reveals the workings of nature’s own earthquake blocker
A new UC Riverside study finds a naturally occurring “earthquake gate” that decides which earthquakes are allowed to grow into magnitude 8 or greater.
Rise of oxygen on Earth: Initial estimates off by 100 million years
New research shows the permanent rise of oxygen in our atmosphere, which set the stage for life as we know it, happened 100 million years later than previously thought. A team including UC Riverside found that oxygen fluctuated dramatically after its early appearance before becoming a permanent constituent of the...
450-million-year-old sea creatures had a leg up on breathing
A new UC Riverside study has found the first evidence of sophisticated breathing organs in 450-million-year-old sea creatures. Contrary to previous thought, trilobites were leg breathers, with structures resembling gills hanging off their thighs.
Research shows we’re surprisingly similar to Earth’s first animals
Today’s humans share genes with 555-million-year-old oceanic creatures missing heads.
Astronomers measure enormous planet lurking far from its star
Scientists aren’t usually able to measure the size of gigantic planets, like Jupiter or Saturn, which are far from the stars they orbit. But a UC Riverside-led team has done it.
