Qing-zhu YinQing-zhu YinModeling Early Meteorite Impacts on the Moon

From the egghead: As our solar system was forming nearly four and a half billion years ago, a planet-sized object struck the early Earth, leading to the formation of the moon, possibly from a hot, spinning cloud of rock vapor called a synestia. But after the Earth and moon had condensed from the vapor, there was another phase of growth as meteorites crashed into both bodies.

Mike OskinMike Oskin | Prepare for an Earthquake

From KCRA 3: 4 Ways to Prepare for an EarthquakeThere are more than 15,000 known faults in California, according to the California Earthquake Authority. Most Californians live within 30 miles of an active one. “It doesn’t have to be scary," UC Davis professor of geology Mike Oskin said. "We are prepared in this state and every individual can do something to be prepared for themselves

From Fox 40: SoCal Earthquakes Renewed Interest in Early Warning App. Is It Coming to Sacramento? Moments before you even feel an earthquake, ShakeAlert is designed to give you a warning. There is no timeline for when the app will reach Sacramento. In the meantime, University of California, Davis professor of geology Michael Oskin recommends taking steps to prepare yourself. “One of the most predictable things about earthquakes is they have aftershocks, so they trigger more earthquakes around them,” Oskin said.

From the Los Angeles Times: Afraid of the Big One? Consider Sacramento, which avoids the worst California quakes

Qing-zhu YinQing-zhu YinEarth Has WAY More Gold Than the Moon and Here's Why

From That may seem odd, given the two worlds' shared (and violent) history. About 4.5 billion years ago, a Mars-size planet dubbed Theia slammed into the proto-Earth, blasting huge amounts of material from both bodies into space. Some of this liberated stuff was incorporated into the bruised and battered Earth, and some coalesced to form the moon. Yin is a member of a research team — led by Meng-Hua Zhu, of the Macau University of Science and Technology in China — that used computer simulations to model millions of impacts on the moon.

John RundleJohn RundleLocal Professor Weighs In on Recent Seismic Activity in Southern California

From Fox 40: “Typically, major earthquakes like that have foreshocks and the small earthquake on July Fourth would have been classified as a foreshock of the 7.1 earthquake,” said John Rundle who is a distinguished professor of physics and earth science at UC Davis. Rundle has studied earthquakes for years and says they're fairly difficult to predict.

Tessa HillTessa HillAs the oceans acidify, these oyster farmers are fighting back

From the Christian Science Monitor: It's often hard to notice ecological changes, even when they threaten catastrophe. One oyster company in California hopes to change that. The oyster farm helps make abstract issues like ocean acidification and climate change concrete, says Tessa Hill, a marine scientist at the University of California in Davis who studies acidification and has developed a partnership with Mr. Sawyer and Hog Island.

Geerat VermeijGeerat VermeijBeyond the visible: What shells can tell us about our world

From ScienceLine: Shells tell a story of evolution that spans over millions of years. Shells — often overlooked on the shores — tell professor Geerat Vermeij a story about evolution that spans millions of years. Vermeij, a leading geologist and author of the famous escalation theory, has been captivated by shells since a young age. His is the story of pursuit of passion despite an obstacle that might deter others. You see, professor Vermeij is blind. Listen to his inspiring story of beauty and undeterred curiosity about the world around us.

Nicholas PinterNicholas PinterSmall Towns, Big Flood Waters

Climate change and sea-level rise are bringing more water to people’s doorsteps, threatening communities from Midwestern America to Jakarta, Indonesia. Entire towns are moving to escape rising waters. But how do towns address these growing threats and still retain their sense of community? To find out, flood expert Nicholas Pinter and his team are visiting dozens of communities across the Midwest  that have moved entirely off the floodplain in a concept called "managed retreat." Read the full, multimedia story of two of those towns — one in Illinois, the other in Wisconsin — at UC Davis Science & Climate,
