Mars, Inc., UC Davis and partners have launched a crowdsourcing initiative to solve the problem of aflatoxin contamination of crops. A series of aflatoxin puzzles will go online on Foldit, a platform that allows gamers to explore how amino acids are folded together to create proteins. The puzzles provide gamers with a starting enzyme that has the potential to degrade aflatoxin. Gamers from around the world then battle it out to redesign and improve the enzyme so that it can neutralize aflatoxin. Successful candidates from the computer game will be tested in the laboratory of Justin Siegel, assistant professor of chemistry, biochemistry and molecular medicine at UC Davis.

The National Science Foundation has awarded $1.6M to the University of California, Davis to analyze the complex relationships between surface water and groundwater supply, agricultural land use and the economic wellbeing of rural, disadvantaged communities.
The project is led by principal investigator Helen Dahlke, an associate professor in the UC Davis Department of Land, Air and Water Resources. The team will develop models to help guide decision-making regarding water management and land use in the state.
New Varieties Bred for Local Conditions
By Alex Russell
Hybrid maize seeds and the yields they make possible can make a big difference for small-scale farmers in developing economies worldwide, especially those who are at risk of poverty and food insecurity. However, low adoption rates are common, especially in sub-Saharan Africa.
Synthetic DNA Approach is Key to Startup’s New Drug
By Lisa Howard
The way Justin Siegel describes it, ordering synthetic DNA is almost as easy as ordering a pair of shoes online.
“You just type it in — or if the protein has been sequenced at one point, we can copy and paste — order it, and it shows up five days later.”
The government of Haiti recently announced a program to fortify wheat flour with iron and folic acid, following a recommendation by UC Davis researchers who calculated that adding these nutrients to wheat flour during milling would prevent infant deaths and improve the health especially of women and children.
The new Haitian program, known by its French acronym RANFOSE, is supported by the United States Agency for International Development (USAID). In addition to adding folic acid and iron to wheat flour, it will fortify vegetable oils with Vitamin A and salt with iodine. RANFOSE will increase the availability of high-quality, fortified staple foods across the country and expand the local production and importation of fortified foods, according to a US Embassy news release.
The advent of farming, especially dairy products, had a small but significant effect on the shape of human skulls, according to a recently published study from anthropologists at UC Davis.
Put another way, our skulls were changed by the invention of cheese.
Researchers at UC Davis, the Boyce Thompson Institute (BTI) at Cornell University, the University of Minnesota and Iowa State University have received a four-year, $10.3 million “Insect Allies” award from the Defense Advance Research Projects Agency (DARPA) to engineer viruses carried by insects that can help in combatting disease, drought, and other yield-reducing stresses in maize.
Could too much linoleic acid be making us sick?
By Diane Nelson
There are good and bad fats, nutritionists say. But not all polyunsaturated fats, the so-called good fats, are created equal. A food chemist at UC Davis is exploring whether eating too much linoleic acid—a type of polyunsaturated fat found mainly in vegetable oils—can cause chronic inflammation, headaches, and other health problems.
Key to Tea’s Benefits May Be in the Soil
By Becky Oskin
Tea has long been linked to human health benefits like preventing cancer and heart disease. But with hundreds of chemical compounds hidden in tea leaves, it is unclear which substances have the strongest effects.
The slew of “healthy” chemicals in tea varies with the variety of plant, how and where it is grown, and how the leaves are processed. Even soil bacteria contribute to a plant’s chemical profile, including its color, taste and aroma.

Understanding how live pigs are traded between villages and backyard farmers can help health agencies better understand how devastating swine diseases spread, according to a study published recently in the journal PLOS ONE.
