CU’s anti-violence production of ‘The Tempest’ to tour Colorado schools
Feb 12th
The Colorado Shakespeare Festival’s highly praised school anti-violence tour continues in spring 2013 with a new program based on “The Tempest” that focuses on themes of vengeance and forgiveness.
Created in conjunction with the Center for the Study and Prevention of Violence at the University of Colorado Boulder, CSF’s “Twelfth Night” anti-bullying tour has now been seen by more than 22,000 Colorado schoolchildren. That inaugural program examined the problem of bullying through the character Malvolio.
The new program explores the character of Prospero, who conjures a mighty tempest to shipwreck his enemies of old on his remote island domain. But even as he plots his revenge on those who wronged him years before, he ponders his actions and at the last moment turns to forgiveness instead.
“The rarer action is in virtue rather than vengeance,” Prospero says, renouncing all his schemes for payback.
“This is really about how to relate to other people and deal with conflict in your life. This performance and the workshops that follow focus on the importance of reconciliation and forgiveness as a tool for ending the cycle of violence,” says CSF Literary Manager Amanda Giguere, who co-created the program with Timothy Orr, interim producing artistic director.
During the program, four professional actors perform an abbreviated version of the play. The actors then lead the students in small-group exercises exploring alternatives to violence that are based on the latest research from CU-Boulder’s Center for the Study and Prevention of Violence.
The play emphasizes that there is always a choice between continuing the “cycles of revenge” and choosing not to retaliate, says Beverly Kingston, director of the center. She notes that 33 percent of American high school students had been in at least one physical fight in the preceding 12 months, according to the 2011 national youth risk behavior survey.
“You can see that in every one of those fights, someone had to make a decision to retaliate for some reason,” Kingston says. “Violence really begins with a decision and we all have a choice how we respond to difficult circumstances in our lives. That’s the message of this play.”
The new play makes use of Japanese bunraku-style puppets to represent some of the characters, including Prospero and his spirit servant Ariel.
In actor and stage manager Caroline Barry’s hands and animated by her voice, Ariel’s sea-blue face and colorful trailing veils seem almost to swim across the stage. With a few simple gestures — a thoughtful nod and touching foreheads with his spirit companion — the puppet Prospero becomes a fully-fledged character.
“We really want you to start imagining the actors’ expressions on the puppets,” says actor Crystal Eisele.
The new program debuts Feb. 12 at the Cole Arts and Sciences Academy in Denver. There are more than 40 schools on the spring schedule — and for the first time, a senior center — and Giguere expects to add more.
CSF’s innovative anti-violence school programs have received tens of thousands of dollars in grant funding and been featured prominently in print, online and television media across Colorado.

CU study: Southwest regional warming likely cause of pinyon pine cone decline
Feb 12th
Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study.
The new study showed that pinyon pine seed cone production declined by an average of about 40 percent at nine study sites in New Mexico and northwestern Oklahoma over the past four decades, said CU-Boulder doctoral student Miranda Redmond, who led the study. The biggest declines in pinyon pine seed cone reproduction were at the higher elevation research sites experiencing more dramatic warming relative to lower elevations, said Redmond of CU’s ecology and evolutionary biology department.
“We are finding significant declines in pinyon pine cone production at many of our study sites,” said Redmond. “The biggest declines in cone production we measured were in areas with greater increases in temperatures over the past several decades during the March to October growing season.”
The cones in which the pinyon seeds are produced are initiated two years prior to seed maturity, and research suggests the environmental stimulus for cone initiation is unseasonably low temperatures during the late summer, said Redmond. Between 1969 and 2009, unseasonably low temperatures in late summer decreased in the study areas, likely inhibiting cone initiation and development.
The study is one of the first to examine the impact of climate change on tree species like pinyon pines that, instead of reproducing annually, shed vast quantities of cones every few years during synchronous, episodic occurrences known as “masting” events. Redmond said such masting in the pinyon pine appears to occur every three to seven years, resulting in massive “bumper crops” of cones covering the ground.
In the new Ecosphere study, the researchers compared two 10-year sequences of time. In addition to showing that total pinyon pine cone production during the 2003-2012 decade had declined from the 1969-1978 decade in the study areas, the team found the production of cones during masting events also declined during that period.
Some scientists believe masting events evolved to produce a big surplus of nut-carrying cones — far too many for wildlife species to consume in a season — making it more likely the nuts eventually will sprout into pinyon pine seedlings, she said. Others have suggested masting events occur during favorable climate conditions and/or to increase pollination efficiency. “Right now we really don’t know what drives them,” Redmond said.
“Across a range of forested ecosystems we are observing widespread mortality events due to stressors such as changing climate, drought, insects and fire,” said CU’s Barger. “This study provides evidence that increasing air temperatures may be influencing the ability of a common and iconic western U.S. tree, pinyon pine, to reproduce. We would predict that declines in pinyon pine cone production may impact the long-term viability of these tree populations.”
Wildlife biologists say pinyon-juniper woodlands are popular with scores of bird and mammal species ranging from black-chinned hummingbirds to black bears. A 2007 study by researchers at the University of Northern Arizona estimated that 150 Clark’s Nutcrackers cached roughly 5 million pinyon pine nuts in a single season, benefiting not only the birds themselves but also the pines whose nuts were distributed more widely for possible germination.
For the new study, Redmond revisited nine pinyon pine study sites scattered throughout New Mexico and Oklahoma that had been studied previously in 1978 by Forcella. Both Forcella and Redmond were able to document pinyon pine masting years by counting small, concave blemishes known as “abscission scars” on individual tree branches that appeared after the cones have been dropped, she said.
Since each year in the life of a pinyon pine tree is marked by a “whorl” — a single circle of branches extending around a tree trunk — the researchers were able to bracket pinyon pine reproductive activity in the nine study areas for the 1969-1978 decade and 2003-2012 decade, which were then compared.
Pinyon pines take three growing seasons, or about 26 months, to produce mature cones from the time of cone initiation. Low elevation conifers including pinyon pines grow in water-limited environments and have been shown to have higher cone output during cool and/or wet summers, said Redmond. In addition to the climate-warming trend under way in the Southwest, the 2002-03 drought caused significant mortality in pinyon pine forests, Redmond said.
“Miranda’s ideas and accompanying results will be of value to ecologists and land managers in the deserts of the Southwest and beyond,” said Forcella, now a research agronomist in the USDA’s Agricultural Research Service. “The work is evidence that the University of Colorado continues to cultivate a cadre of high-caliber graduate students for which it rightfully can take tremendous pride.”
Pinyon nuts, the Southwest’s only commercial source of edible pine seeds today, were dietary staples of indigenous Americans going back millennia.

“American Gut” sequencing project involving CU raises $340,000 online
Feb 7th
In hopes of better understanding nutrition and health, the University of Colorado Boulder is playing the leading science role in a “crowd funding” effort that has raised more than $340,000 for a project designed to sequence the gut bacteria of thousands of people around the world.
Known as the American Gut project, the effort raised the money through a crowdfunding effort online in which collective groups of people pool money to support various initiatives, said CU-Boulder Associate Professor Rob Knight of the BioFrontiers Institute. The $340,477 raised for the American Gut project is the largest amount of money ever raised through crowdfunding for a science project, said Knight, who is co-leading the effort with Jeff Leach, founder of the Human Food Project.
The money contributed by 2,005 funders will be used to sequence gut bacteria from about 3,500 people said Knight. Each human is believed to harbor roughly 10 trillion microorganisms — about 10 times more than the number of cells in the human body — that undertake a number of important functions ranging from digesting food to the strengthening of immune systems.
In 2009, a consortium of 200 researchers from 80 institutions organized by the National Institutes of Health, including Knight, mapped the normal microbial makeup of healthy humans as part of the $173 million Human Microbiome Project. Building on the massive NIH effort, the American Gut project will be an “open source” effort, meaning participants will have access to the data gathered to help understand how diet and lifestyle may contribute to human health through the interaction of our microbiomes, cells and genes, said Knight.
“The outpouring of public support for this research project demonstrates how public awareness of the role of our microbial systems in human health is growing,” said Knight, the project’s scientific lead who holds joint faculty appointments in CU-Boulder’s chemistry and biochemistry department and computer science department. “By looking at samples from the general public, we can get a far better sense of what a ‘normal’ microbiome is and what factors have the largest effects.”
The scientists are particularly interested in how diet and lifestyle, whether by choice or necessity, affect peoples’ microbial makeup, including those suffering from particular autoimmune diseases or who have food allergies, said Knight, also a Howard Hughes Medical Institute Early Career Scientist.
“The large number of participants in American Gut, coupled with our ongoing work in Africa and South America, will allow us to explore the impact of diet and lifestyle between western and more traditional societies,” said Leach. “We may find that our modern gut microbiome has shifted significantly away from our ancestral one, but reinstating some of that primal balance may be within our grasp.”
“I’m super excited about helping to build a system that not only integrates so much data but also presents it to the user in a useful way,” said Meg Pirrung, a graduate student in Knight’s lab. “This is an amazing opportunity for me and everyone involved.”
Daniel McDonald, a graduate student in the BioFrontiers Institute’s IQ Biology Program, said the American Gut project is allowing him to hone his interdisciplinary experience. IQ Biology students are involved in semester-long rotations that immerse them in disciplines ranging from mathematical and computational biology to biophysics and bio-imaging. “It’s an extraordinary opportunity for discovery,” he said.
The American Gut data also will also be used in the several IQ Biology Program courses taught by Knight with Manuel Lladser, an associate professor in the applied mathematics department. Last year the IQ Biology program at CU’s BioFrontiers Institute, which offers doctorates in eight disciplines, was awarded a $3 million grant from the National Science Foundation’s Integrative Graduate Education and Research Traineeship, or IGERT.
Second Genome, a biotech company headquartered in San Bruno, Calif., is working with the American Gut project to explore the connection between the human microbiome and type 2 diabetes, said company president and CEO Peter DiLaura.
“The American Gut project has succeeded in bringing together the largest citizen science network ever for human microbiome sample collection,” DiLaura said. “By building this extensive reference database, we now have the opportunity to explore the connections between the human microbiome and metabolic and inflammatory diseases.”
Although the first round of funding that enabled the project to commence has ended, a second phase also allows anyone in the world to join, said Leach. Once the scientific results are in from the initial group of participants, a third phase will allow new participants to obtain additional analyses crucial to understanding the microbiome.
“By integrating the tens of thousands of environmental samples that the scientific community has provided from around the world and applying powerful modeling approaches, we will be able to gain unprecedented insight into the links between our own microbes and those in our environment,” said Argonne National Laboratories microbial ecologist Jack Gilbert, a member of the Earth Microbiome Steering Committee.
“With advances in DNA sequencing, we are moving towards a world in which no infectious disease goes undiagnosed, and in which we have full knowledge of the microbes that inhabit us and our surroundings,” said Knight. “By participating in this project, thousands of people are helping us to make this future a reality.”
