Coming to CU: High-tech hallucinogenic "Swarm Wall"
Jun 4th
A monthlong summer exhibit at the University of Colorado Boulder Art Museum will feature a dynamic new media composition based on innovative robotics technology.
Called “Swarm Wall,” the large-scale interactive piece displays changing fields of color, light and sound that are driven by a distributed form of artificial intelligence.
As many as 70 intelligent “nodes” behind the piece create a swarming effect when they detect movement and communicate it with one another. The nodes exhibit swarm behavior because each performs actions solely based on its own plan and the actions of its immediate neighbors.
The 42-by-12-foot installation is the first product from a new art and technology research group on campus. The group was launched by faculty members Michael Theodore of the College of Music, who received a $44,000 grant from CU’s Innovative Seed Grant Program last year to support the collaboration, and Nikolaus Correll of the computer science department.
Also involved in the Swarm Wall is Ken Sugawara, a visiting computer science professor from Tohuku Gakuin University in Japan who is an expert in animal flocking behavior, the inspiration behind the patterns the wall displays.
The seed grant, which Correll and Theodore say already has helped them attract additional funding, was the first step toward establishing an active lab where students, faculty and professional researchers from various disciplines collaborate on cutting-edge applications of artificial intelligence.
“We’re now calling it the ‘if’ lab because we want to see what happens if artists put engineers in front of tough problems,” said Correll, who is providing space for the growing group within his own robotics laboratory in the Engineering Center at CU-Boulder.
“We want to assemble some basic, inexpensive tools that students can use to explore and to develop new applications of robotics,” Correll said.
Scattered around the lab last week were a collection of small custom circuit boards, electronic panels, items resembling ping pong balls and various other components that are being used to assemble robotic devices.
An assembly of circuit boards connected with bright orange cables also was mounted on a partition in the lab in preparation for the installation of Swarm Wall. Small mechanical arms or flippers waved back and forth as the “brains” behind the Swarm Wall were tested. Sometimes the movement was synchronized, while other times a ripple effect would occur in response to some stimuli.
“Artistic exploration can help computer scientists and engineers to ask questions they wouldn’t have otherwise asked,” said Theodore, who also serves as director of the ATLAS Center for Media, Arts and Performance.
“The difference between arts and science is very diffuse; both want to discover new things,” Theodore said. “The cool thing about art is that we can explore systems that are not of interest to classical funding agencies, but might be so after maturing in a lab like the ‘if’ lab.”
Swarm Wall is one of four pieces in “Michael Theodore: Field Theory,” an exhibition of kinetic sculpture, sound, lighting and works on paper, running June 15 through July 14 at the CU Art Museum. The exhibition is free and open to the public. An opening reception will be held on June 15, from 6 to 8 p.m. For additional information, visitors may call the CU Art Museum at 303-492-8300 or go to http://cuartmuseum.colorado.edu.
CU researchers plotting the "Map of Life
May 22nd
A research team involving Yale University and the University of Colorado Boulder has developed a first public demonstration version of its “Map of Life,” an ambitious Web-based endeavor designed to show the distribution of all living plants and animals on the planet.
The demonstration version allows anyone with an Internet connection to map the known global distribution of almost 25,000 species of terrestrial vertebrate animals, including mammals, birds, amphibians, reptiles and North American freshwater fish. The database, which continues to expand, already contains hundreds of millions of records on the abundance and distribution of the planet’s diverse flora and fauna.
“We are taking 200 years of different types of knowledge coming from different sources, all documenting the locations of species around the world and compiling them in a way that will greatly enhance our knowledge of biodiversity,” said CU-Boulder Associate Professor Robert Guralnick of the ecology and evolutionary biology department, part of the Map of Life research team. “Such information could be used by any organization that needs to make informed decisions regarding land management, health, conservation and climate change.”
The initial version of the map tool being released today is intended to introduce it to the broader public, according to the researchers. It allows users to see several levels of detail for a given species — at its broadest, the type of environment it lives in, and at its finest, specific locations where the species’ presence has been documented. One function allows users to click a point on the map and generate a list of vertebrate species in the surrounding area. More functions will be added over time, according to the team.
“It is the where and the when of a species,” said Walter Jetz, associate professor of ecology and evolutionary biology at Yale and the project lead. “It puts at your fingertips the geographic diversity of life. Ultimately, the hope is for this literally to include hundreds of thousands of animal and plant species and show how much or indeed how little we know of their whereabouts.”
A paper by Jetz, Guralnick and Jana McPherson of the Calgary Zoological Society describing the evolving Map of Life technology tool appeared in a recent issue of the journal Trends in Ecology and Evolution.
By highlighting the known abundance and distribution of species, the researchers hope to identify and fill knowledge gaps and also offer a tool for detecting change over time. They expect the map tool will prove useful for professional scientists, wildlife and land managers, conservation organizations and the general public.
The team is using information gleaned from a wide variety of sources, including field guides, museum collections and wildlife checklists that involved scientists, conservation organizations and “citizen scientists.” The project’s success will depend on participation by other scientists and informed amateurs, and subsequent versions of the mapping tool will offer mechanisms for users to supply new or missing information about the distribution and abundance of particular species.
Jetz called the Map of Life “an infrastructure, something to help us all collaborate, improve, share and understand the still extremely limited geographic knowledge about biodiversity.” The team continues to work on several other tasks and challenges, including who will be contributing data and how information supplied by the contributors will be verified and curated.
“A small but powerful next step is to provide a means for anyone, anywhere on the globe to use their mobile devices to instantly pull up animal and plant distributions and even get a realistic assessment on the odds of encountering a particular species of wildlife,” said Guralnick, who also is the curator of invertebrate zoology at the University of Colorado Museum of Natural History.
Guralnick said the Map of Life project is following in the footsteps of other knowledge repositories like the GenBank project, a National Institutes of Health-funded effort with a public database of more than 135 million gene sequences from more than 300,000 organisms that allows users to explore genes and genomes using bioinformatics tools. In the biodiversity arena, the Global Biodiversity Information Facility in Copenhagen has developed an important resource that provides access to more than 300 million records of plant and animal occurrences, which is one of the distributional databases being used by the Map of Life team.
The National Science Foundation has provided initial support for the Map of Life project. Other supporters are the Encyclopedia of Life; the International Union for the Conservation of Nature; and the Senckenberg Research Institute and Natural History Museum, and the Biodiversity and Climate Research Center, both in Germany.

Boulder water festival for students to be held on Wednesday
May 14th
20th annual Boulder Water Festival teaches students how to conserve and protect water
More than 1,100 4th and 5th grade students from 45 classrooms in 17 Boulder area schools will participate in the 20th annual Boulder Water Festival from 9 a.m. to 2 p.m. on Wednesday, May 16, at the University Memorial Center (UMC) on the University of Colorado at Boulder campus, 1669 Euclid Ave.
The nationally recognized water festival engages local students in hands-on activities about where Boulder’s drinking water comes from and how to protect and conserve this valuable natural resource. Students attend a series of classes to discover the geography, history, and science of water; explore the Boulder Creek watershed and its geology; and study the animals and plants that rely on water for survival.
Participating classes also complete the “Operation: Water Festival” program, a standards-based series of pre-festival classroom learning activities. The program provides a complete teacher’s packet featuring lesson guides, student worksheets and trivia questions for each water topic. Topics include fundamental water awareness, conservation, pollution prevention and flooding. Student “Water Agents” receive a certificate upon completion of the classroom activities.
A key benefit of the “Operation: Water Festival” materials is a take-home book for families. The book encourages students to work with family members to complete activities related to local water resources, conservation and protection.
“Students really have a complete learning experience,” said Samantha Messier, science director for the Boulder Valley School District (BVSD). “This provides a great learning tool to help students learn about one of our most important natural resources in Colorado.”
The Boulder Water Festival will commemorate its 20th anniversary as part of the statewide celebration of 2012, The Year of Water in Colorado. Nearly 19,000 BVSD and Boulder area students have participated in the festival since its inception in 1992.
Festival sponsors include the City of Boulder, the Keep it Clean Partnership, Northern Water, the UMC, CU Boulder’s Office of Community Relations and the U.S. Bureau of Reclamation.
