Bioengineers Team with High School Students to Study Age-Related Heart Disease
Bioengineering professor Adam Engler recently launched a six-week fruit fly experiment with a group of 11th grade biology students in a study of age-related heart disease. The question driving the project is whether genetic mutations in the heart, mutations that are common in humans as we age and that are correlated with poor heart function, also contribute to a shortened lifespan?

Bioengineers uncover cause, treatment for insulin resistance in shock patients
Bioengineers at the University of California, San Diego have discovered that insulin resistance in shock patients is caused by the leakage of powerful digestive enzymes from the small intestine that eat away and destroy the insulin receptor in cells. Reporting in the journal Shock, the team has also found a way to stop these enzymes’ destructive path by blocking them in the intestine, where they are normally used to digest food. The research team includes Frank DeLano, lead investigator, and co-investigator Geert Schmid-Schönbein, professor and chair of bioengineering at UC San Diego Jacobs School of Engineering. Doctors have long known that trauma patients going into shock are at risk of developing acute insulin resistance, leading to hyperglycemia. The pancreas releases insulin to deliver glucose to cells to convert into energy for the body. When cells are unable to process insulin properly, a condition known as insulin resistance, blood sugars rise and the pancreas releases more insulin, compounding the problem. Until now, doctors have not known what mechanism causes insulin resistance to develop in shock patients or how to treat it. Full Story

Computer Scientists Develop New Approach to Sort Cells Up to 38 Times Faster
A team of engineers led by computer scientists at the University of California, San Diego, has developed a new approach that marries computer vision and hardware optimization to sort cells up to 38 times faster than is currently possible. The approach could be used for clinical diagnostics, stem cell characterization and other applications. Full Story

'Wildly Heterogeneous Genes'
Cancer tumors almost never share the exact same genetic mutations, a fact that has confounded scientific efforts to better categorize cancer types and develop more targeted, effective treatments. In a paper published in the September 15 advanced online edition of Nature Methods, researchers at the University of California, San Diego propose a new approach called network-based stratification (NBS), which identifies cancer subtypes not by the singular mutations of individual patients, but by how those mutations affect shared genetic networks or systems.

New electron beam writer enables next-gen biomedical and information technologies
The new electron beam writer housed in the Nano3 cleanroom facility at the Qualcomm Institute is important for electrical engineering professor Shadi Dayeh’s two major areas of research. He is developing next-generation, nanoscale transistors for integrated electronics; and he is developing neural probes that have the capacity to extract electrical signals from individual brain cells and transmit the information to a prosthetic device or computer. Achieving this level of signal extraction or manipulation requires tiny sensors spaced very closely together for the highest resolution and signal acquisition. Enter the new electron beam writer.

Conference for African-American Researchers in Mathematics Connects Students to Mentors
For Lauren Crudup, a third-year bioengineering student at the University of California, San Diego, the Conference for African-American Researchers in the Mathematical Sciences (CAARMS) presented a unique opportunity to learn just how applicable mathematics is in the real-world—especially compared to the pure mathematics she learned in high school and earlier undergraduate courses.

Faculty Invited to Exclusive Symposium for 'Creative Young Engineers'
Jacobs School of Engineering professors Karen Christman and Gert Lanckriet are among 81 of the nation’s most “creative young engineers” selected to attend this year’s U.S. Frontiers of Engineering Symposium by the National Academy of Engineering. Participation in the event is by invitation-only to engineers between the ages of 30-45 who have “demonstrated accomplishment in engineering research and technical work with recognizable contributions to advancing the frontiers of engineering,” according to an NAE announcement.

Technology-Enhanced Learning: From Campus to the World
The academic landscape is changing rapidly, due in no small part to recent advances in technologies to enable, enhance and deliver teaching and learning to a worldwide audience. At the University of California, San Diego, administrators and faculty are particularly focused on using technology to transform the undergraduate learning experience (saving money in the process). They’re doing this in the context of the UC San Diego Education Initiative, as well as the Technology-Enhanced Learning (TEL) Initiative jump-started by Calit2’s Qualcomm Institute. Both programs are helping to formulate a way forward for the campus, with the Education Initiative focused on policy, and the TEL Initiative experimenting with various models of online learning.
