The award was presented to the Aggie inventors during the finals of the three-day global iGEM (International Genetically Engineered Machines) competition in Boston. The competition, this year featuring 245 teams from Asia, Europe, Latin America and North America, challenges student teams to design and build biological systems or machines and present their inventions in the international competition.
The students had spent several months designing and building the palm-sized biosensor, which they dubbed OliView. The biosensor is equipped to quickly and easily evaluate the chemical profile of oil, providing producers, distributors, retailers and ultimately consumers with an effective, inexpensive way to ensure olive oil quality.
Verifying olive oil quality is a concern for consumers – many of whom are willing to pay higher prices for the health benefits and flavor of true, extra-virgin olive oil. And honest olive oil producers want to prevent other producers from passing off sub-par olive oil as the real deal, while retailers, distributors and producers want a quick, easy way to ensure olive oil quality.
In addition helping detect fraudulent olive oil, the students' new biosensor will also monitor for good oil that may have gone rancid with age.
The team of undergraduate students included Lucas Murray, Brian Tamsut, James Lucas, Sarah Ritz, Aaron Cohen and Simon Staley, with Yeonju Song serving as the “shadow” or alternate team member. You can tune into Aaron Cohen's recent Nov. 6 Science Friday interview during a discussion of synthetic biology.

At the same time, chefs and food buyers at universities, particularly the University of California, are selecting for high-quality fruits and vegetables, produced locally and sustainably. Universities with strong food sustainability programs are rightfully proud of what they're doing to educate students about food production, health, and nutrition. UC Davis Dining Services prioritizes the purchase of locally grown food (ideally within a 50-mile radius of campus). Most University of California campuses have similar programs.
At UC Davis, fresh roma tomatoes are picked each August from the 300-acre Russell Ranch, part of the campus's Agricultural Sustainability Institute, then processed within hours by campus Dining Services to provide year-round tomato sauce for pizza, pasta, and ratatouille. All told, 10,000 pounds of tomatoes are processed during a two-week period in August. About 29 percent of the total food served in the campus's residential dining halls is from local, organic or sustainable sources.
Emma Torbert, an academic coordinator at the UC Davis Agricultural Sustainability Institute, noted, “Connecting the food system to the research is really interesting. A lot of times there is confusion about where our food is coming from. The more people are educated, the more educated decisions they can make.”
Many UC Davis faculty and staff are so impressed with the food choices at the dorms that they purchase individual meal tickets and enjoy lunches made with the campus-grown tomatoes, herbs, and other vegetables, all of which are part of the daily food array. Public dinners are also offered periodically at the dorms so that community members can sit amongst students to taste and learn about the sustainability programs in the dorms.

Not until students turn 21 can they taste the wine and beer they make and learn to assess its sensory quality. Learning the characteristics of a wide assortment of good (and not-so-good) wines and beers is an important component of winemaking and brewing. Having to wait until their junior or senior year to learn these skills is a disadvantage for these students.
Legislation (AB 1989) has been proposed by California Assemblyman Wesley Chesbro (D-North Coast) that will allow students, ages 18 to 21, enrolled in winemaking and brewery science programs to taste alcoholic beverages in qualified academic institutions. The students can taste, but not consume — which means they must learn the professional practice of spitting during the tasting process.
“Winemakers taste wine daily during harvest to quickly make critical decisions as the winemaking is underway,” Waterhouse said. “Our students need to start learning this skill here, with our guidance. And, they also have to get over the embarrassment of spitting — after every taste.”
Chik Brenneman, the UC Davis winemaker, said that the bill, if passed, “will allow students to move on to the sensory program a lot sooner, before they've finished most of their winemaking classes. Earlier sensory training will help them when they go to work in the industry.”
If the legislation passes, it will benefit enology and brewing students at UC Davis, which is the only University of California campus to offer undergraduate degrees in viticulture and enology and in brewing science (an option within the food science major).
While parents of college students may worry that the bill will open the door to widespread drinking, Waterhouse and Brenneman both noted that the focus of the bill is so narrow that its impact will benefit a limited number of students, and that it's unlikely to lead to excessive drinking. They say that the over-21 students routinely spit what they're tasting in a standard industry manner, and that “drinking” in class is not a problem.
With passage of this bill, which is backed by the University of California, the state will join 12 other states that have allowed this educational exemption for students.

“It’s more than a way to sell food. It builds community, and that’s a powerful thing for students to learn,” said Raoul Adamchak, who coordinates the CSA and the Market Garden where the produce is grown.
Over the years, those involved in UC campuses’ food systems have garnered powerful lessons from students as well, resulting in organic gardens, student farms and increasingly sustainable food options at dining halls. These student-initiated components of campus food systems continue to nurture student opportunities to learn and get involved.
While the Student Farm has run its CSA for 16 years, the farm has been a part of the campus food system for 30 years by selling fresh organic produce to the UC Davis Coffee House, which is run by Associated Students, UC Davis. Most recently, it began selling produce to Sodexo-run UC Davis Dining Services – further diversifying its customer base.
“When Dining Services initially wanted to buy from us, we were hesitant,” said Mark Van Horn, director of the Student Farm. “Our CSA was well established and is still our highest grossing market. We’re at the upper limits of production and didn’t think we could grow more without negatively effecting education – the primary purpose of the farm. What changed our minds is that we realized our relationship with them is about education as well as production. We’re collaborating with Dining Services to educate students – more students than ever – about the entire food system.”
“We’re trying to engage students in the food system so they can learn about where their food comes from and what’s in it,” said Dani Lee, UC Davis University Dining Services’ sustainability manager.
Dining Services labels the origin of campus-produced food. It regularly hosts outreach events, features displays about and organizes tours of the Student Farm, Russell Ranch and other campus-based partners. It has also established internships for students interested in waste reduction, gardening and sourcing food more locally.
Lee and Van Horn hope these efforts will help inspire students to learn more.
“We’re seeing more interest from students today than ever before,” Van Horn said. “I attribute it to a bigger cultural awakening catalyzed by folks like Michael Pollan and Eric Schlosser. They figured out that if you talk about agriculture, the environment and the whole food system just as ‘food,’ it’s more interesting. Students are coming in with more knowledge and commitment to these issues than ever before. Encouraging them to get actively involved in the food system is a great way to nurture what students years ago began when they founded the Student Farm, started the Coffee House, and got University of California administrators to commit to meeting a list of sustainability criteria by 2020.”
UC Davis Dining Services already exceeds the UC goal of 20 percent sustainably produced food by 2020, but it isn’t stopping there.
“We’re constantly working on sourcing more products locally,” Lee said.
Lauren Cockrell, a fourth-year UC Davis student majoring in Sustainable Agriculture and Food Systems is pleased with the trajectory and believes ensuring student involvement in the effort to build a more sustainable food system is key.
“I’d like the next step to be an independent, entirely student-run food retail business that, at its core, values sustainability,” she said.
Back in the 1960s and 1970s, when organic was a foreign word to most Americans, students at UC Davis and UC Santa Cruz were part of a wave of environmental activism that sought alternatives to agricultural methods that distanced people from farms and relied on heavy use of chemical pesticides and fertilizers.
In 1971, student enthusiasm for a garden at UC Santa Cruz that used natural cultivation methods grew so much so that 14 acres were set aside for the UC Santa Cruz Farm and Garden to create more opportunities to research and teach organic farming. Meanwhile, a student-led seminar at UC Davis on alternative agriculture mushroomed into a group that lobbied campus administration for land to create a farm that would explore sustainable agriculture. With support from the College of Agricultural and Environmental Science, the UC Davis Student Farm formed in 1977 on 20 acres of what was then a remote corner of campus.
In the decades that followed, these student-led movements helped spur the growth of organic farming and formed the foundations for innovative sustainable agriculture research and education programs at UC Davis and UC Santa Cruz that have served as models for other universities.
