New Research Traces the Impact of Volcanic Activity on Climate Change

A newly published study shows that for the majority of Earth’s history, continental arc volcanism has been the main driver of long-term climate variability. A geology-based analysis of Earth’s climate history over the past 700 million years provides evidence that climate change has occurred traditionally through slow shifts in the release of carbon dioxide — […]

Yale Researchers Put Prehistoric Mystery Meat to the Test

A famous dinner for scientists in the 1950s supposedly served meat from a woolly mammoth that was discovered frozen in the arctic. Yale scientists obtained a preserved sample of the meat, which DNA analysis proves is actually from a modern green sea turtle. The green sea turtle is an endangered species, so the flesh sample […]

Researchers Find a Soft Spot in a Tectonic Slab

Using land-based seismic stations, researchers from Yale University found that part of the Nazca Plate weakened and deformed as it bent and slid under the adjoining South American Plate. The Earth’s tectonic plates may be more flexible than previously thought as they slide underneath each other and dive deep below the surface, according to new […]

Temperature of Ancient Seas Shape Global Climate

In a newly published study, scientists from Yale University detail the differences in ocean temperatures over the last 5 million years by creating a historical record for sea temperature gradients and comparing it with state-of-the-art climate model simulations. The study is published in the journal Nature Geoscience. Sea temperature gradients (contrasts) in the tropics and […]

Organa Crater is Rich in Frozen Ammonia

Astronomers have discovered a striking contrast between one of the fresh craters on Pluto’s largest moon Charon and a neighboring crater dotting the moon’s Pluto-facing hemisphere. The crater, informally named Organa, caught scientists’ attention as they were studying the highest-resolution infrared compositional scan of Charon. Organa and portions of the surrounding material ejected from it […]

Researchers Discover a Mysterious Mound on the Lunar Surface

Geologists from Brown University detail the discovery of a giant mound near the Moon’s south pole that appears to be a volcanic structure unlike any other found on the lunar surface. They believe the mound was formed by unique volcanic processes set in motion by the impact that formed the basin. The formation, known as […]

Elevated Organic Compounds Found in Pennsylvania Drinking Water from Hydraulic Fracturing

Engineers at Yale University reveal that the presence of organic compounds in groundwater aquifers in Pennsylvania is likely the result of surface releases from hydraulic fracturing operations and not migration from gas wells or deep shale layers. In the largest study of its kind, a Yale-led investigation found no evidence that trace contamination of organic […]

New Study Reveals Earth’s Inner Core was Formed 1 – 1.5 Billion Years Ago

New data from the University of Liverpool reveals that the Earth’s inner core was formed 1 – 1.5 billion years ago as it “froze” from the surrounding molten iron outer core. The inner core is Earth’s deepest layer. It is a ball of solid iron just larger than Pluto which is surrounded by a liquid […]

Scientists Describe Ancient Water Flows and Lakes on Mars

Newly published research from Caltech describes ancient water flows and lakes on Mars, and what this might mean about the ancient climate. We have heard the Mars exploration mantra for more than a decade: follow the water. In a new paper published October 9, 2015, in the journal Science, the Mars Science Laboratory (MSL) team […]

New Images of Pluto's Moon Charon

New images from NASA’s New Horizons Spacecraft are the highest resolution images yet of Pluto’s largest moon, Charon. The images reveal a surprisingly complex and violent past. At half the diameter of Pluto, Charon is the largest satellite relative to its planet in the solar system. Many New Horizons scientists expected Charon to be a […]

NASA Confirms Liquid Water Evidence on Mars

New research using NASA’s Mars Reconnaissance Orbiter reveals the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They darken […]

Researchers Discover Fossils from Dinosaurs That Lived in Cold Weather

Scientists from Florida State University and the University of Alaska Fairbanks have uncovered a new species of duck-billed dinosaur, a 30-footlong herbivore that endured months of winter darkness and probably experienced snow. The skeletal remains of the dinosaurs were found in a remote part of Alaska. These dinosaurs were the northernmost dinosaurs known to have […]

Study Shows Massive Eruptions Likely Triggered Mass Extinction

A new study from MIT reveals that the Siberian Traps erupted at the right time, and for the right duration, to have been a likely trigger for the end-Permian extinction. Around 252 million years ago, life on Earth collapsed in spectacular and unprecedented fashion, as more than 96 percent of marine species and 70 percent […]

New Research Shows Turtles Share a Recent Common Ancestor with Birds and Crocodiles

New fossil evidence reveals that turtles share a recent common ancestor with birds and crocodiles. There’s a twist in the turtle timeline. Thanks to new fossil evidence, paleontologists are able to prove that turtles share a recent common ancestor with birds and crocodiles. The discovery may settle a longstanding argument among scientists about the origins […]
