Most climate models do not yet account for a new UC Riverside discovery: methane traps a great deal of heat in Earth’s atmosphere, but also creates cooling clouds that offset 30% of the heat. Read More
With the first paper compiling all known information about planets like Venus beyond our solar system, scientists are the closest they’ve ever been to finding an analog of Earth’s “twin.” Read More
A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a UC Riverside experiment. Read More
Not all pollution comes from people. When global temperatures increase by 4 degrees Celsius, harmful plant emissions and dust will also increase by as much as 14 percent, according to new UC Riverside research. Read More
The magnitude 7.8 earthquake that killed — by current count — more than 6,000 people in Turkey and Syria on Sunday was produced by the same type of fault underlying most of California. Sunday’s event could be felt more than 200 miles from its epicenter, and it has produced a humanitarian disaster in a region...
Earth is currently in the midst of a mass extinction, losing thousands of species each year. New research suggests environmental changes caused the first such event in history, which occurred millions of years earlier than scientists previously realized. Read more.
Trapped for millennia, the tiniest liquid remnants of an ancient inland sea have now been revealed. The surprising discovery of seawater sealed in what is now North America for 390 million years opens up a new avenue for understanding how oceans change and adapt with changing climate. Read more.
An Earth-like planet orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets. Read more.
"Broccoli, along with other plants and microorganisms, emit gases to help them expel toxins. Scientists believe these gases could provide compelling evidence of life on other planets. These types of gases are made when organisms add a carbon and three hydrogen atoms to an undesirable chemical element. This process, called methylation, can turn potential toxins...
"Scientists at UC Riverside are suggesting something is missing from the typical roster of chemicals that astrobiologists use to search for life on planets around other stars — laughing gas. Chemical compounds in a planet’s atmosphere that could indicate life, called biosignatures, typically include gases found in abundance in Earth’s atmosphere today." Read more.
"A pair of massive earthquakes in Mexico — 7.6 on Sept. 19 and 6.8 on Sept. 22 — have some in Southern California on edge, wondering whether the Golden State is next. Here, UC Riverside seismologist Abhijit Ghosh weighs in on the likelihood of more shakers, and how to prepare for them. Ghosh is an...
"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 between the star and the...
"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 seemingly tiny event could trigger...
"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. “It’s long bothered me why Jupiter doesn’t have even more amazing rings that would put Saturn’s to shame,” said UCR astrophysicist Stephen Kane...
"Using light-capturing proteins in living microbes, scientists have reconstructed what life was like for some of Earth’s earliest organisms. These efforts could help us recognize signs of life on other planets, whose atmospheres may more closely resemble our pre-oxygen planet. The earliest living things, including bacteria and single-celled organisms called archaea, inhabited a primarily oceanic...
"Marilyn Fogel, endowed geoecology professor at UC Riverside, died on May 11 at her home in Mariposa, Calif. She was 69. She pioneered the use of different forms of the same chemical element, called isotopes, to understand the life history of organisms, both modern and ancient. In so doing, she helped develop biogeochemistry as a...
"New 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. Ozone is a gas composed of three oxygen atoms. Many studies have described ozone in the stratosphere, and its role in shielding people from the sun’s harmful ultraviolet radiation. Closer...
"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 object from spinning, a phenomenon...
University of California, Riverside scientists will join a first-of-its-kind effort to map out California’s so-called “Lithium Valley,” and learn whether it can meet America’s urgent demand for lithium in a sustainable, environmentally friendly way. Lithium is required for making electric vehicle batteries and other devices that store and use electricity. As the world transitions away...
For transforming our understanding of the earliest animals on Earth, UC Riverside Professor Mary Droser has won the National Academy of Sciences’ prestigious Charles Doolittle Walcott Medal. The medal, part of the academy’s Award in Early Earth and Life Sciences, is an honor bestowed on only one scientist in the world every eight years. It...
