An Ancient Partnership: Co-Evolution of Earth Environments and Microbial Life

NASA - NASA-supported scientists have examined the long and intricately linked history of microbial life and the Earth's environment. By reviewing the current state of knowledge across fields like microbiology, molecular biology, and geology, the study looks at how microorganisms have both shaped and been shaped by chemical properties of our planet's oceans, land, and...

How cleaning up shipping cut pollution — and warmed the planet

GRIST - Michael Diamond thought he’d have to wait until this year, at least, to have enough data to understand how a shipping regulation aimed at curbing pollution affected the clouds that deck the ocean. “They’re so variable. They’re so wispy. They’re so ever, ever changing,” he said. “So you really often need a lot...

Microbes laid the foundation for early life on Earth

EARTH.COM - We exist, thrive, and ponder upon life, but when it comes to understanding its beginnings, we’ve always found ourselves at a crossroads. Where did we come from? What did the world look like when life first emerged? A recent paper from UC Riverside is now helping us piece together this complex puzzle using...

Greenhouse gases could indicate alien life — if we ever find them

ASTRONOMY - In a new study published in The Astrophysical Journal, astronomers propose looking for greenhouse gases in the atmospheres of exoplanets using tools like the James Webb Space Telescope (JWST). But rather than searching for an advanced species suffering the consequences of climate change, such gases might be a sign of something else: terraforming...

Scientists Identify Greenhouse Gases Which Could Signal an Inhabited Planet

ANCIENT ORIGINS - While we have yet to identify life on any other planet or anywhere else in space, a new study has revealed the telltale signs which could indicate a planet being inhabited. Researchers at the University of California, Riverside (UCR) discovered that greenhouse gases, much like the ones emitted by our very own...

Volcanic Ash Preserved Trilobite Fossils in Surprising Detail at 'Prehistoric Pompeii'

SMITHSONIAN MAGAZINE - Scientists have uncovered intricately preserved fossils of trilobites that are providing new insights into the extinct invertebrates’ anatomy. The animals had been buried in modern-day Morocco after volcanic ash blanketed them underwater more than 500 million years ago. This preservation created 3D fossils that revealed several new features of trilobites, researchers reported...

Stunning trilobite fossils include soft tissues never seen before

SCIENCE NEWS - Paleontologists studying rocks from Morocco have unearthed the most exquisitely preserved trilobite fossils yet discovered. The new lifelike fossils update our understanding of the evolution and biology of these extinct ocean-dwelling arthropods. The details are so great that soft tissue parts of the trilobites, including the mouth and digestive tract, are clearly...

Life Lessons from Hell-House Venus

NAUTILUS - Hold a grain of sand up to the night sky at arm’s length. There are thousands of galaxies in that miniscule fraction of the heavens. Galaxies like ours hold hundreds of billions of stars—a good portion of which host planets. And a number of these are in the “habitable zone,” that just-right distance...

How We Could Detect A Terraformed Planet Using Existing Technology

IFLSCIENCE - There may come a point (perhaps for humans, perhaps not) where a civilization may wish to terraform a planet in their Solar System or beyond. Perhaps an environmental disaster was looming on their planet, or they spotted a nearby neighbor planet that looked like – with a few finishing touches – it could...

Greenhouse gases can help detect alien life on distant planets

EARTH.COM - The search for extraterrestrial life has captivated our imaginations for centuries. Now, a study from the University of California, Riverside (UCR) suggests a tantalizing possibility: we may be able to detect alien activity and civilizations by identifying artificial greenhouse gases they use to terraform planets. What is terraforming? Terraforming, a concept popular in...
