Titanium Clubs Can Cause Golf Course Fires, UCI Study Finds
Sparks fly when head hits rocks in the rough, potentially igniting brush
“One fire almost reached homes before they stopped it. This unintended hazard could potentially lead to someone’s death,” said Samueli School chemical engineering & materials science professor James Earthman, lead author on the paper. “A very real danger exists, particularly in the Southwest, as long as certain golf clubs remain in use.” He suspected that the titanium heads on some clubs designed for use in “the rough” – natural areas off irrigated fairways – could be to blame for the fires.

Thomas Yuen ’74 earns UCI Alumni Association’s Extraordinarius award
Thomas Yuen, entrepreneur, philanthropist and community leader, will receive UC Irvine’s Extraordinarius award May 15 at the 44th annual Lauds & Laurels ceremony, sponsored by the UCI Alumni Association. He is among 18 campus faculty, staff, students and alumni who will be honored.
“Lauds & Laurels is our opportunity to publicly recognize and thank those people who make a positive impact on the university and our community,” said Jeff Minhas ’04, interim assistant vice chancellor for alumni relations and UCIAA executive director.
The event, which is being held in the UC Irvine Student Center’s Pacific Ballroom, begins with a reception at 6 p.m.
A 1974 graduate of UC Irvine, Yuen has been widely recognized for his superlative business accomplishments, philanthropy and volunteer work. He is the first of the university’s 150,000 alumni to garner both the Extraordinarius award and the UCI Medal, presented in 1990 for his exemplary service.
Yuen arrived in the U.S. from Hong Kong in 1970 and four years later received a bachelor’s degree in electrical engineering from UC Irvine’s Henry Samueli School of Engineering. In 1980, he and two friends founded personal computer manufacturer AST Research, which grew into a Fortune 500 company. Later, Yuen became chairman and CEO of SRS Labs, a world leader in audio and voice technology. Today he’s chairman and CEO of PrimeGen Biotech LLC, a private stem cell research company.
He has served on the UC Irvine Foundation board of trustees and continues to be a major donor – along with his wife, Misa – to the campus and UC Irvine Douglas Hospital, particularly in support of cutting-edge stem cell research.

A Hundred Tiny Hands Hopes to Inspire Young Scientists
Michelle Khine is known for her playful approach to science. She used a toy – Shrinky Dinks – to invent a method of quickly and cheaply developing custom microfluidic chips for researchers to use in their labs. Now she and her student researchers are inventing toys to inspire kids to not only conduct science, but also become inventors themselves.
The associate professor of biomedical engineering, most recently named one of Fast Company’s Most Creative People in Business 1000, issued a challenge to the graduate students working in her laboratory. “Many of the students in my lab serve as Rocket Science Tutors, so they are working with kids already,” says Khine. “I wanted them to think about how to get children interested in becoming inventors.”
They came up with three ideas for educational toy kits that are “fun, creative, and chock-full of scientific content and ah-ha moments for any child at heart.” Khine and her students formed an academic nonprofit co-op called A Hundred Tiny Hands and have launched a Kickstarter campaign to raise $50,000 to produce the kits. Contributors to the Kickstarter campaign will receive the kits and other fun gifts in return (such as kid-sized lab coats), or they can donate to a school in need and have their donation matched with contributions from Tiny Hands.
Each kit’s packaging features a cartoon character based on the corresponding graduate student and includes a booklet using the character to help children learn the scientific concepts. The idea with the kits is to create a virtual community of young inventors. A Hundred Tiny Hands plans to hold fun challenges – who can build the biggest Polytropolis city with the maximum number of lit up buildings generated from a nine-volt battery? It also intends to encourage kids to upload their own invention ideas, and the graduate students would help them make and produce their own custom kits, including a cartoon character made from their likeness to star as the main character in the booklet and on the box.

Biomedical Engineer Designs a Living Cell with Second DNA Replication System
UC Irvine’s Chang Liu has created an engineered living cell with a second DNA replication system that mutates independently of and without harming the cell’s original genome. This parallel replication cell works like a two-lane highway -- with a fast lane and a slow lane -- for direct evolution in a lab setting. With it, biomedical engineers will be able to rapidly evolve a huge array of biomolecules with custom desired functions. Liu and his research group published their work in the March issue of Nature Chemical Biology.
“Using the evolutionary process in a bioengineering lab is historically a very inefficient endeavor because you have to constantly move DNA into and out of cells,” explains Liu, an assistant professor in biomedical engineering. “This is because high mutation rates, necessary to create enough diversity to find new function on laboratory timescales, are only available in a test tube. High mutation rates are not available inside cells. In fact, organismal mutation rates must be kept extremely low because modern organisms have large complex genomes that are easily broken by high mutation rates.”
The parallel replication system designed by Liu can be made highly error-prone without hurting the genome, and any gene encoded on the new system will undergo rapid evolution. “Genes of interest placed in the fast lane can potentially evolve thousands to millions of times faster than they would if they were encoded in the genome, or the slow lane,” says Liu.

UC Irvine to lead “Team Orange” at Solar Decathlon 2015
Deputy Energy Secretary announces contestants, decathlon site in campus visit
UC Irvine and three fellow Orange County campuses will compete in the U.S. Department of Energy’s Solar Decathlon 2015, the international student competition to design and build the best solar-powered home. Chapman University, Irvine Valley College and Saddleback College will join UC Irvine as “Team Orange” to create a residence that reflects the traits of the drought-resistant, sun-loving California poppy.
“I’m thrilled that Team Orange has been selected to compete in this world-class event,” said Gregory Washington, dean of UC Irvine’s Samueli School of Engineering, who will lead the effort. His research specialty is “smart” materials that harvest energy. “We and our partners will show California and the nation that our campuses and Orange County lead the way on innovative, affordable solar power and other clean energy advances. The home team can definitely win.”
U.S. Deputy Secretary of Energy Daniel Poneman will visit UC Irvine today to announce the 20 teams selected to compete in Solar Decathlon 2015, which will be held at the Orange County Great Park. (The event will be live streamed at www.energy.gov/live.) Teams, from colleges and universities across the country and around the world, will now begin the nearly two-year process of building solar-powered houses that are affordable, innovative and highly energy-efficient.
“As President Obama made clear in the State of the Union address, we need an all-of-the-above energy strategy that creates a safer and more sustainable planet, while ensuring American students and workers have the skills they need for the challenging jobs of today and tomorrow,” Poneman said. “The Solar Decathlon provides the next generation of America’s architects, engineers and entrepreneurs with the real-world experience and training they need to strengthen U.S. innovation and support new, clean sources of energy.”

The Children’s Heart Foundation and American Heart Association Sponsor Two Cardiovascular Science Projects in Biomedical Engineering
The Children’s Heart Foundation has awarded Kheradvar $200,000 over two years to support a hybrid tissue-engineered heart valve. Kheradvar and his research team are developing a patient-specific heart valve prosthesis with self-regenerating capacity. “This approach to engineering heart valves holds promise for combining the mechanical valves’ long-term durability advantages with biological valves’ self-regenerating capacity and improved biocompatibility and hemodynamics,” explains Kheradvar, a Fellow of the American Heart Association.
Kheradvar has also received a Grant-in-Aid from the American Heart Association to study patients with right-sided heart failure, using UC Irvine’s state-of-the-art 4-D-flow echocardiography technology. Despite the fact that right-sided heart failure may carry a worse prognosis than left-sided heart failure, almost no quantitative information is available on flow patterns inside the right ventricle. The main reasons for this lack of knowledge are the highly 3-D flow within the right side of the heart, and the inability of current imaging modalities to quantitatively map such 3-D blood flow patterns.
“This study should help us better understand the blood flow features in failing right hearts and devise more efficient therapies for these patients,” says Kheradvar.

Engineering Students Test their App in Local Art Center
“In the museum world, we are always looking for ways to deepen visitor’s engagement with art,” explains Kate Hoffman, executive director of the Huntington Beach Art Center (HBAC). So when a group of graduate students from the engineering and computer science departments approached her with an idea for using technology to enhance visitors’ experience, she loved it.
The students tested their idea – a mobile application called Kaleri – at the HBAC in early December. Kaleri (which stems from the Greek word for gallery) does two things. First it provides a technologically savvy way for users to delve into a piece of artwork. Using innovative indoor positioning technology, the application recognizes the art that is closest to the visitor and displays it on a mobile device. Visitors can interact with a given piece of art by rating, bookmarking, using social networks to share with their friends, and storing this interaction for future retrieval. The second objective of Kaleri is to understand visitors’ behaviors – common routes, most viewed items, time spent at each artwork, comments posted, and returning visitor information – to help museums provide more engaging experiences. During the pilot test, 40 people used Kaleri to explore HBAC’s sculpture-based exhibit of contemporary art: Reverberation.
“This was an opportunity for our visitors to instantly learn more about a piece,” says Hoffman. “We are a city owned and operated institution with a limited budget. We aren’t able to offer audio tours. This was a way to access information through a type of technology that many people are familiar with and that generates excitement.”
