ANN ARBOR — Nisin, a common food preservative, may slow or stop squamous cell head and neck cancers, a University of Michigan study found.
What makes this particularly good news is that the Food and Drug Administration and the World Health Organization approved nisin as safe for human consumption decades ago, says Yvonne Kapila, the study’s principal investigator and professor at the University of Michigan School of Dentistry. (more…)
COLLEGE PARK, Md. – The so-called “fiscal cliff” has already begun dampening the U.S. economy – even before it officially kicks in – and by year’s end will have cut 2012 GDP an estimated six-tenths of one percent, says a new study conducted by researchers at the University of Maryland’s Interindustry Forecasting Project (Inforum).
The study, called Fiscal Shock: America’s Economic Crisis, is one of the first to look beyond the first year effects of the combined federal spending cuts and tax increases. It projects an escalating impact into 2014 and beyond, as “multiplier” effects of fiscal contraction kick in. (more…)
Jack Turner, UW assistant professor of political science, is the author of “Awakening to Race: Individualism and Social Consciousness in America,” published this month by University of Chicago Press. He answered a few questions about his book for UW Today.
What’s the central concept behind “Awakening to Race”?
The book addresses the challenge of racial justice by asking, “What does it mean to be a self-aware human being? What does it mean to be awake to reality?”
In part, it means confronting the worst aspects of ourselves and our lives. Being awake to reality in the United States means confronting the ways America’s history of slavery, Jim Crow and white supremacy still shapes the present — the opportunities we have or we lack, the confidence we have in ourselves or fail to have in others, the ways our chances for success are still color coded.

Study part of growing body of knowledge surrounding gene-environment interplay
TORONTO, ON – It is time to put the nature versus nurture debate to rest and embrace growing evidence that it is the interaction between biology and environment in early life that influences human development, according to a series of studies recently published in a special edition of the Proceedings of the National Academy of Sciences (PNAS).
“Biologists used to think that our differences are pre-programmed in our genes, while psychologists argued that babies are born with a blank slate and their experience writes on it to shape them into the adults they become. Instead, the important question to be asking is, ‘How is our experience in early life getting embedded in our biology?’” says University of Toronto behavioural geneticist Marla Sokolowski. She is co-editor of the PNAS special edition titled “Biological Embedding of Early Social Adversity: From Fruit Flies to Kindergarteners” along with professors Tom Boyce (University of British Columbia) and Gene Robinson (University of Illinois).

MENLO PARK, Calif. — As much as 44 billion tons of nitrogen and 850 billion tons of carbon stored in arctic permafrost, or frozen ground, could be released into the environment as the region begins to thaw over the next century as a result of a warmer planet according to a new study led by the U.S. Geological Survey. This nitrogen and carbon are likely to impact ecosystems, the atmosphere, and water resources including rivers and lakes. For context, this is roughly the amount of carbon stored in the atmosphere today.
The release of carbon and nitrogen in permafrost could exacerbate the warming phenomenon and will impact water systems on land and offshore according to USGS scientists and their domestic and international collaborators. The previously unpublished nitrogen figure is useful for scientists who are making climate predictions with computer climate models, while the carbon estimate is consistent and gives more credence to other scientific studies with similar carbon estimates.

The wide swings in debate performances by this year’s presidential candidates reflect the fact that in modern campaigns, a candidate’s image is the message, according to linguistic anthropologists who have studied presidential campaigns.
Candidates send important messages to voters through even their smallest gestures, the researchers say. For example, in this year’s first debate, President Barack Obama often looked down at the podium and was criticized for appearing disengaged. In subsequent debates Obama directly addressed his Republican opponent, former Massachusetts Gov. Mitt Romney, and increased the use of a hammering hand gesture sometimes called the “power grip.” (more…)
Police officers and students exhibit an apparent “hierarchy of bias” in making a split-second decision whether to shoot suspects who appear to be wielding a gun or, alternatively, a benign object like a cell phone, research conducted by the University of Colorado Boulder and San Diego State University has found.
Both the police and student subjects were most likely to shoot at blacks, then Hispanics, then whites and finally, in a case of what might be called a positive bias, Asians, researchers found. (more…)
Professor’s new book examines nature, utopia and the garden
“the result of humanity’s attempt to carve out an ideal place in nature, thereby fashioning a ‘perfect’ earth” — is the subject of a new book, co-authored and edited by the University of Delaware’s Annette Giesecke.
Earth Perfect? Nature, Utopia, and the Garden is a lushly illustrated, 303-page volume that brings together essays from writers and experts across disciplines to study the relationship — historical, present and future — between humanity and the garden. (more…)
