California’s beaches grew some 500 acres in 40 years, says new study. Inside the haves and have-nots
Gary Griggs, a coastal erosion expert at U.C. Santa Cruz, described how a submarine canyon near Point Mugu has been slowly reconfigured (for reasons that aren’t clear) in a way that it effectively swallows up sand previously pushed farther down the coast by currents.

‘Super-Jupiter’ exoplanet is not so Jupiter-like, UCSC study finds
Xi Zhang, a professor of Earth and planetary science at UC Santa Cruz, has discovered that an exoplanet classed as a “super-Jupiter” has substantial differences from our solar system’s largest planet — and in fact, has much in common with Mars. Exoplanet VHS 1256b, located 40 light years away from Earth, was identified in 2015.

Why Brown Dwarfs May Explain the Main Differences Between Stars and Planets
The atmospheres of brown dwarfs can be surprisingly similar to those of gas giant planets, too, complete with multi-layered clouds and powerful wind-driven storms. That makes them great windows into the atmospheric processes that shape our own solar system’s giant planets, as well as the super-Jupiter exoplanets discovered outside our stellar neighborhood, according to a…

Which fault line do you live on? An earthquake guide for California.
While both the northern and southern sections of the San Andreas fault are locked, storing up energy that needs to be released, the central part is creeping and less charged.”The true nightmare scenario is that the southern San Andreas has so much extra energy in it because it’s so overdue that it blows through the…

Mars Has Lightning, Scientists Prove
This is the first time there has been convincing evidence that electrical activity on Mars is actually occurring, says Francis Nimmo, a planetary scientist at the University of California, Santa Cruz, who wasn’t involved in the study.

Why California is seeing an earthquake cluster right now
Emily Brodsky, an earthquake physicist at UC Santa Cruz, said it’s difficult to draw any conclusions from the activity in San Ramon. “Although it’s the kind of thing you might expect to happen before a big earthquake, we can’t distinguish that from the many, many times that has happened without a big earthquake,” she told…

If another country tested nuclear weapons, here’s how we’d know
Seismologist Thorne Lay of the University of California, Santa Cruz has been involved with nuclear monitoring research for decades. Science News spoke with Lay to clarify what we know about nuclear testing around the globe.

UCSC astronomy Ph.D. survived war and helped build Kosovo’s first observatory. Now she’s bringing the cosmos to Bay Area classrooms
After surviving the Kosovo War and witnessing her first solar eclipse as a child, UC Santa Cruz astronomy Ph.D. student Pranvera Hyseni turned a moment of wonder into a lifelong mission to bring astronomy education to her homeland.

Alien worlds may be able to make their own water
“They can basically be their own water engines,” says Quentin Williams, an experimental geochemist at the University of California Santa Cruz who was not involved with the new work.

Cruise ships are flocking to Alaska to chase ice. But receding glaciers are leaving a new threat behind
Rocks expand and contract when they heat and cool, said Noah Finnegan, a geomorphologist and professor at the University of California Santa Cruz. Rocks that have been covered in a layer of ice for 1,000 years have been at a consistent temperature.

California may be at high risk of ‘supershear’ earthquakes. Scientists fear we’re not ready
Past large supershear earthquakes have occurred on shearing faults that are long, straight and shallow, said Thorne Lay, a distinguished professor of earth and planetary sciences at UC Santa Cruz. The San Andreas fits this description.
