Question: “What did you do this summer?” Answer: “I built the Advanced Light Source.”

It’s the rare undergraduate who can say they spent their vacation building a third-generation synchrotron, but that’s exactly what Seno Rekawa did in the summer of 1991 as an intern at Lawrence Berkeley National Laboratory. It was an auspicious start to his career. Less than five years later, he was working as a full-time engineer at Berkeley Lab and now is a regular mentor to budding high school and college engineers.

Berkeley Lab’s Center for Science and Engineering Education (CSEE), with its range of internship offerings, helps to fulfill one of the Lab’s mandates, which is to inspire and prepare this country’s next generation of scientists, engineers and technicians. This year more than 70 current and recent college students and almost 20 high school and college instructors participated in a CSEE program, working with Berkeley Lab researchers on science projects spanning from cancer research to cosmology to biofuels.

Scientists Helped Design NASA Mission Concept to Search for Life on Europa

AUSTIN, Texas — Scientists at the University of Texas at Austin’s Institute for Geophysics helped develop a blueprint for a possible future NASA lander mission to Europa, an icy moon of Jupiter that has a global ocean covered by an ice shell. Europa’s large reservoir of liquid water has long enchanted planetary scientists with the possibility of harboring life. Many experts believe it to be the most likely place in our solar system besides Earth to host life today. The proposed mission is designed to assess the moon’s habitability by studying its surface composition, ice shell, ocean and geology.

Don Blankenship, senior research scientist at the institute, is part of the science definition team commissioned by NASA to draft the report, which appears in the August 2013 issue of Astrobiology. Blankenship and two colleagues — Krista Soderlund, postdoctoral fellow at the institute; and Britney Schmidt, formerly a postdoctoral fellow at the institute, now assistant professor at the Georgia Institute of Technology — developed a part of the mission scenario that would use sound waves to study the moon’s icy shell, deep ocean and possible shallow lakes.

Coastal Antarctic Permafrost Melting Faster Than Expected

AUSTIN, Texas — For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a regularly recurring phenomenon, and the change could offer a preview of melting permafrost in other parts of a warming Antarctic continent.

Tracking data from Garwood Valley in the McMurdo Dry Valleys region of Antarctica, Joseph Levy, a research associate at The University of Texas at Austin’s Institute for Geophysics, shows that melt rates accelerated consistently from 2001 to 2012, rising to about 10 times the valley’s historical average for the present geologic epoch, as documented in the July 24 edition of Scientific Reports.

Scientists Image Vast Subglacial Water System Underpinning West Antarctica’s Thwaites Glacier

AUSTIN, Texas — In a development that will help predict potential sea level rise from the Antarctic ice sheet, scientists from The University of Texas at Austin’s Institute for Geophysics have used an innovation in radar analysis to accurately image the vast subglacial water system under West Antarctica’s Thwaites Glacier. They have detected a swamp-like canal system beneath the ice that is several times as large as Florida’s Everglades.

The findings, as described last week in the Proceedings of the National Academy of Sciences, use new observational techniques to address long-standing questions about subglacial water under Thwaites, a Florida-sized outlet glacier in the Amundsen Sea Embayment considered a key factor in projections of global sea level rise. On its own, Thwaites contains enough fresh water to raise oceans by about a meter, and it is a critical gateway to the majority of West Antarctica’s potential sea level contribution of about 5 meters.

Over-Confident CEOs Can Put Companies at Risk, MU Study Finds

COLUMBIA, Mo. — CEOs need to demonstrate strong leadership and good decision-making skills, but CEOs with over-confidence can involve their companies in riskier ventures and put investors’ funds at risk, according to a new study from the University of Missouri, Georgia Tech University and the University of Texas-Arlington.

“Over-confident CEOs feel they have superior decision-making abilities and are more capable than their peers,” said Stephen Ferris, professor of finance in the MU Trulaske College of Business. “Unfortunately, they tend to make decisions about mergers or acquisitions that can be viewed as risky. For example, CEOs who are over-confident tend to target companies that do not focus on their core line of business. Generally speaking, mergers that diversify companies don’t work.” (more…)

Particle Accelerator That Can Fit on a Tabletop Opens New Chapter for Science Research

AUSTIN, Texas — Physicists at The University of Texas at Austin have built a tabletop particle accelerator that can generate energies and speeds previously reached only by major facilities that are hundreds of meters long and cost hundreds of millions of dollars to build.

“We have accelerated about half a billion electrons to 2 gigaelectronvolts over a distance of about 1 inch,” said Mike Downer, professor of physics in the College of Natural Sciences. “Until now that degree of energy and focus has required a conventional accelerator that stretches more than the length of two football fields. It’s a downsizing of a factor of approximately 10,000.” (more…)

Hidden Wildfires Taking Big Toll on Amazon Rainforest

Using an innovative satellite technique, NASA scientists have determined that a previously unmapped type of wildfire in the Amazon rainforest is responsible for destroying several times more forest than has been lost through deforestation in recent years.

In the southern Amazon rainforest, fires below the forest treetops, or “understory fires,” have been hidden from view from NASA satellites that detect actively burning fires. The new method has now led to the first regional estimate of understory fire damages across the southern Amazon. (more…)

AUSTIN, Texas — The economic status of African Americans in Texas has significantly declined during the first decade of the 21st century, according to a policy report released by the Institute for Urban Policy Research & Analysis (IUPRA) at The University of Texas at Austin.

The report, led by IUPRA Research Fellow Shetal Vohra-Gupta, raises important questions about several issues, such as racial disparities in economic status of families, including median income and overall poverty rate. The economic toll is greatest among African American single mothers. (more…)
