UCLA Recruits Academic Specialist

Posted on April 3, 2014

Under general supervision of the directors of the W.M. Keck Foundation Center for isotope geochemistry, the specialist conducts ion microprobe investigations, provides primary maintenance and support for the facility, assists visiting scientists to acquire data using the ims 1270 ion microprobe, develops and implements applications and software improvement, and undertakes a program of independent, externally funded geological or cosmochemical research. Ph.D. required Those interested in the position should send a CV and cover letter to Kathleen Micham. Salary commensurate with experience.


Boyce and his team of researchers show through a study of apatites that the origin of water on the Moon is uncertain. In UCLA Today: http://newsroom.ucla.edu/portal/ucla/misleading-mineral-may-have-caused-271755.aspx


Using a cutting-edge research technique, UCLA researchers led by EPSS Professor Aradhna Tripati have reconstructed the temperature history of a region that plays a major role in determining climate around the world. The findings, published online Feb. 27 in the journal Nature Geoscience, will help inform scientists about the processes influencing global warming in the western tropical Pacific Ocean. The study analyzes how much temperatures have increased in the region near Indonesia, and how ocean temperatures affect nearby tropical glaciers in Papua New Guinea and Borneo. Researchers also evaluated the accuracy of existing climate model predictions for that region. The findings illustrate that the region is very sensitive to climate change and that it has warmed considerably over the last 20,000 years, since the last ice age.


Astronomers, including Professor David Jewitt, have witnessed for the first time the breakup of an asteroid into as many as 10 smaller pieces. The discovery is published online March 6 in Astrophysical Journal Letters. Though fragile comet nuclei have been seen falling apart as they near the sun, nothing resembling this type of breakup has been observed before in the asteroid belt. NASA's Hubble Space Telescope photographed the demolition.


Researchers led by Caroline Beghein, assistant professor of Earth, planetary and space sciences in UCLA's College of Letters and Science, used a technique called seismic tomography to study the structure of the Pacific Plate — one of eight to 12 major plates at the surface of the Earth. The technique enabled them to determine the plate's thickness, and to image the interior of the plate and the underlying mantle (the layer between the Earth's crust and outer core), which they were able to relate to the direction of flow of rocks in the mantle.


California's largest collection of meteorites, and the fifth-largest collection in the nation, is on display in the new UCLA Meteorite Gallery, which is free to the public. The museum, located in UCLA's Geology Building (Room 3697) is open weekdays from 9 a.m. to 4 p.m. and on some weekend afternoons; please visit the gallery's website for details.


The NASA THEMIS and ARTEMIS missions drew an impressive crowd at the 4th annual Exploring Your Universe outreach event, held at UCLA in Los Angeles, on Nov. 17, 2013. Representing two of UCLA's active space missions, the exhibit exposed the public to "space weather," the study of the sun's activity and influence on Earth's protective magnetic shield, the magnetosphere. Visitors were intrigued by informative posters and stunning videos on the electrical connection between our sun and the planets, and had the opportunity to ask questions from real space scientists and student researchers-in-training. Visitors also witnessed the debut of a specially built display called the Planeterrella, an up-close demonstration of the solar wind and famed Northern Lights.
