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.
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...
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.
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...
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.
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.
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.
A new UC Riverside study finds a naturally occurring “earthquake gate” that decides which earthquakes are allowed to grow into magnitude 8 or greater.
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...
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.
Today’s humans share genes with 555-million-year-old oceanic creatures missing heads.
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.
