A Vision of the Mexican Revolution

The latest ARTSblock exhibit, called “Mexico at the Hour of Combat: Sabino Osuna’s Photographs of the Mexican Revolution,” looks back more than 100 years to a vision of the Mexican revolution from Sabino Osuna. The virtually unknown photographer took dramatic images of the revolution from 1910 to 1914.

Osuna was a a commercial photographer in Mexico City whose work shifted from portraiture and architectural studies to photo history when the revolution began. The title of the exhibit is also the name of a 118-page book edited by UCR Professor Emeritus Ronald Chilcote. Published by Laguna Wilderness Press, it is based on the Osuna Collection of 427 glass negatives of the Mexican Revolution, held in UC Riverside Libraries Special Collections & Archives.

The show coincides with the anniversary of the Mexican Revolution (Nov. 20, 1910), when Francisco “Pancho” Villa and Pascual Orozco led the first insurrectionist attack.  The exhibit continues through Jan. 5 and will tour the country after that.

Nanotechnology Research Moves From Lab to Market

UCR has granted an exclusive license to The Idea Zoo Inc. to commercialize nanotechnology research developed in the lab of Yadong Yin, an associate professor of chemistry.

The Idea Zoo, a leading developer and licensor of advanced materials and technologies headquartered in Santa Clara, Calif., was granted exclusive rights to seven patents that cover various aspects of advanced superparamagnetic colloidal nanocrystals (CNCs). Specifically, the patents focus on magnetically tunable photonic crystals and the ability to commercialize them.

The Idea Zoo will undertake the development and commercialization of CNCs spanning several industries ranging from high-security applications to commercial applications for on-demand color-changing products. The agreement spans the life of the patents. UCR will receive royalties from products developed from these licensed technologies and will receive equity in The Idea Zoo Inc.

Buy Firewood Locally, Prevent the Spread of Disease

When choosing firewood, natural resources experts ask that people use local firewood to avoid moving harmful insects and plant diseases into and around California.

“Buy firewood from a local source close to your home to prevent the spread of insects and diseases, such as the goldspotted oak borer, sudden oak death and emerald ash borer,” said Thomas Scott, a UCR conservation biologist who studies these invasive pests.

“Firewood is one of the least-regulated natural resource industries in California,” said Scott, a UC Cooperative Extension specialist, “but this is a situation where the university can play a critical role in changing behavior through research and education rather than regulation.”

Scott and his UC Cooperative Extension colleagues are working with the U.S. Forest Service, the California Firewood Task Force and other agencies to educate and discourage woodcutters, arborists, firewood dealers and consumers from transporting infested wood.

Firewood can harbor harmful insects and plant pathogens. Moving around infested wood can introduce those pests and pathogens to new areas where they might take hold and could have devastating impacts to trees, our natural resources and local communities. Even wood that looks safe can harbor destructive pests.

Redhead Mice Develop Melanoma Without UV Light

Researchers, including UCR chemists, have found that the type of skin pigment predominantly found in red-haired, fair-skinned individuals may itself contribute to the development of melanoma, suggesting that blocking UV radiation, which continues to be essential, may not be enough.

Led by scientists at the Massachusetts General Hospital, the research team performed lab experiments, in the absence of any UV radiation, on strains of mice that were nearly identical genetically except for the gene that controls the type of pigment melanin produced. When the researchers genetically disabled all pigment production in a group of red hair/fair skinned mice, they found that something about the pigment itself, and not other aspects of being red-haired and fair-skinned, was leading to melanoma.

Yinsheng Wang, a professor of chemistry  whose lab was involved in the research, said, “Our contribution to the research, which provides a key line of evidence to support the research paper’s central hypothesis, lies in the quantitative measurement of the level of oxidative DNA damage in mouse skin tissues.”

The UCR component of the research was supported by a grant to Wang from the National Cancer Institute of the National Institutes of Health.  Besides Wang, Jin Wang, a former postdoctoral fellow, and Candace Guerrero, a graduate student, are UCR co-authors on the research paper. Study results appeared online in Nature on Oct. 31.
