Associate Professor Caroline Beghein is quoted today in the Huffington Post regarding a recent earthquake swarm in the San Francisco Bay Area.

Research published this week in the Proceedings of the National Academy of Science by EPSS postdoc Beth Ann Bell, graduate student Patrick Boehnke, and Professor T. Mark Harrison, along with Stanford geophysicist Wendy Mao, provides evidence suggesting the existence of life on Earth before 4.1Ga. Their article " Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon" is garnering much attention from national and international news agencies*. A UCLA press release can be found here and the link to the PNAS article is here. Congratulations, Beth Ann, Patrick, and Mark.

Rob Eagle, Aradhna Tripati, and colleagues have just published a paper in Nature Communications wherein they compared measurements of isotope clumping in modern and Cretaceous dinosaur eggshells to show that "variable thermoregulation likely existed among the non-avian dinosaurs and that not all dinosaurs had body temperatures in the range of that seen in modern birds".

Research geochemist and Adjunct Assistant Professor Jeremy Boyce has a new paper in Science Advances, a online-only gold open access journal from AAAS, the publisher of Science. Jeremy and colleagues measured chlorine and hydrogen isotope ratios in apatite in lunar basalts finding that the chlorine provides a signature of the degassing of a lunar magma ocean during the early differentiation of the Moon

Researcher positions available at EPSS

UCLA solicits applications for one or more Researchers at the Assistant or Associate level, in the field of Space Physics, at the Institute of Geophysics and Planetary Physics, Department of Earth, Planetary and Space Sciences. For more information about the institute visit: and about EPSS visit: The institute's Space Physics Center carries out investigations of the solar wind, and the magnetospheres, ionospheres and atmospheres of the Earth and planets. The successful candidate will have completed significant independent research in space physics and/or have a strong track record in space hardware development.

The primary responsibilities will be to conduct studies on key space physics questions. The successful candidate will participate actively in a diverse and broad space physics research environment across UCLA, spanning basic plasma theory, simulations, and experimental space physics. Candidates can apply at They should include a full CV, a short statement of research interests, and names of three individuals familiar with their work Position will remain open until filled.

In the 1960s, NASA launched six satellites to study the Earth’s atmosphere, magnetosphere and the space between Earth and the moon. Using observations from those satellites, Christopher Russell, a UCLA graduate student at the time, detected mysterious plasma waves in the Van Allen radiation belts, the donut-shaped rings surrounding the Earth that contain high-energy particles trapped by the planet’s magnetic field.

A new high profile paper came out in the journal Geology today with Jeremy Boyce as co-author. It addresses how quickly a cooled magma chamber can reheat and erupt in Yellowstone.
