One-of-a-kind, natural surface bike park to open June 11 in Boulder
Jun 6th
Media interview opportunities available in advance of Valmont Bike Park grand opening
What do you call 40 acres of twisting trails, mild to wild dirt, structural jumps, strategically-placed sand pits, logs, boulders and staircases? While off-road cyclists may soon call it, “Shangri La,” we call it, “Valmont Bike Park.”
Opening for the first time at 9 a.m. Saturday, June 11, the City of Boulder Parks and Recreation Department’s latest park development has already been hailed as an outstanding bike park by the International Mountain Biking Association (IMBA).
“Cyclists from around the nation will be totally floored by what they see,” said IMBA Executive Director Mike Van Abel. “Based on its many options for riding natural-surface trails, the diversity of both technical and non-technical features and the outstanding quality of the build, Valmont will be among the top venues in the country for this style of biking.”
The City of Boulder’s Parks and Recreation Department will open the newly-developed park with a grand opening event from 9 a.m. to 4 p.m. on Saturday, June 11. The event will feature an official ribbon-cutting ceremony at 10 a.m. with comments from council members, including Deputy Mayor Ken Wilson and Parks and Recreation Director Kirk Kincannon. Food and bicycle gear vendors, a cycling demonstration (on the park’s slopestyle features) and public riding in the park will round out the day’s activities. The event is free and open to the community.
The park contains a pump track, dual slalom and slopestyle riding loop as well as elements for a competition cyclo-cross course. The park also includes training and skill building trails, a toddler playground, event plaza, restrooms, parking and outstanding city and Flatiron views. Developed with the support and partnership of the local cycling community, Boulder Mountainbike Alliance (BMA) and organizations such as the PLAY Boulder Parks Foundation and Great Outdoors Colorado, the 40-acre Valmont Bike Park encompasses natural-surface amenities for multiple riding styles and skill levels.
“We are very excited to open this flagship park,” Kincannon said. “We invested in a collaborative partnership with BMA and the off-road cycling community to design and build this portion of Valmont City Park. The result is a park worthy of our internationally-recognized athletic community—one that will be a daily asset to local kids, families, riders and businesses and also attract events and riders from all over the country and the world.”
Note to Media: Media interviews with Parks and Recreation Department Director Kirk W. Kincannon will be available on a scheduled basis on June 7 and 8. The media is encouraged to attend the grand opening event on June 11. Please contact Shelly Ruspakka by June 7 at RuspakkaS@BoulderColorado.gov or 303-413-7214 to set up a media interview or to discuss plans for the opening event.
The bike park is currently closed due to allow completion of construction. The park will open to cycling on June 11. No footage of park use or demonstrations will be available until June 11.
Plague identified in City of Boulder
Jun 3rd
Go ahead, try to pet me!!(I’ll rip yer face off)
Boulder, CO – A domestic cat living in the 2500 block of 6th Street has tested positive for plague. Additionally, a dead squirrel found at the intersection of 8th and Maxwell Avenue has tested positive for plague. As a result, the Mapleton Hill neighborhood has been posted with signs listing precautionary measures to avoid plague.
This is the first time plague activity has been confirmed in Boulder County this season, and public health officials want to remind residents about how to protect themselves against plague.
“We want people to understand what steps they should take to protect themselves, their family members, and their pets,” said Boulder County Public Health (BCPH) Environmental Health Division Manager Joe Malinowski. “Because plague is most commonly transmitted by fleas, taking steps to avoid flea exposure will be most helpful in preventing this disease.”
Public health officials recommend the following precautions to reduce the likelihood of being exposed to plague:
· AVOID FLEAS! Protect pets with flea powder, and keep pets on a leash and out of wild rodent habitats.
· STAY OUT of areas that wild rodents inhabit. If you enter areas with wild rodents, wear insect repellent and tuck your pants cuffs into your socks to prevent flea bites.
· AVOID all contact with wild rodents, including squirrels; do not feed or handle them.
· NEVER TOUCH sick or dead animals with your bare hands. Use a long-handled shovel to place dead animals in a garbage bag, and then place the bag in an outdoor garbage can.
· PREVENT rodent infestations around your house. Clear plants and materials away from outside walls, reduce access to food items, and set traps.
· TREAT known rodent sites around your home with flea powder or a suitable insecticide.
Plague occurs naturally in Colorado and is an infectious disease spread by fleas to wild rodents and other small mammals, such as squirrels, rats, prairie dogs, and rabbits. Bubonic plague is the most common form of plague and occurs after a bite from an infected flea. Plague can spread to humans when infected fleas from squirrels, prairie dogs, and other wild rodents bite a human.
Household pets, such as dogs and especially cats, can either get plague or carry infected fleas home to their owners. In rare instances, plague can be transmitted to people from cats sick with plague. “Keeping cats indoors is the best way to protect them from getting plague,” said Malinowski. “In addition, pet owners should discuss with their veterinarians the best way to protect pets from fleas.”
Symptoms of plague infection include high fever, extreme fatigue, and painful swollen lymph nodes (called bubos). If you observe these symptoms in a person or pet, it is important to contact your health care provider or veterinarian immediately. Plague can be treated with antibiotics, but this treatment is most successful when the disease can be diagnosed quickly.

GUT MICROBES IN HUMANS AND OTHER MAMMALS HEAVILY INFLUENCED BY DIET, SAYS NEW STUDY C U Boulder
May 20th
You are what you eat whether you’re a lion, a giraffe or a human — at least in terms of the bacteria in your gut.
A new study led by the Washington University School of Medicine and involving the University of Colorado Boulder shows gut microbial communities in humans and in a wildly diverse collection of mammals carry out core physiological functions that are heavily influenced by whether they are carnivores, herbivores or omnivores.
The researchers sequenced intestinal microbes in stool samples from 33 mammalian species living in the wild or in zoos in St. Louis and San Diego. In addition to identifying the bacterial species living in the mammalian intestines, they characterized the pool of genes present in each microbial community and their related functions, said senior study author Dr. Jeffrey Gordon of the Washington University School of Medicine in St. Louis.
CU-Boulder professor and study co-author Rob Knight said despite the wide variation of mammals selected for the study, the different gut microbial communities share a set of standard metabolic functions common to all species that play a key role in digestion and immune health. Understanding the variation in human microbial intestine communities holds promise for future clinical research, said Knight, a faculty member in the chemistry and biochemistry department and the computer science department.
A paper on the subject was published in the May 20 issue of Science. Other co-authors on the study included CU-Boulder’s Justin Kuczynski, Dan Knights, Jose Clemente and Antonio Gonzalez, Washington University School of Medicine’s Brian Muegge and Luigi Fontana, and Bernard Henrissat of the Archictecture et Fonction des Macromolecules Biologiques in Marseille, France.
“This was the first time we were able to relate the microbial community members to the specific metabolic functions that were being performed,” said Knight, who also is a Howard Hughes Medical Institute Early Career Scientist. “This is surprising because even members of the same bacterial species can have genomes that are up to 40 percent different in terms of gene content.”
The team extracted DNA from the mammals and humans and used powerful computer methods to sort gene fragments and match them to the DNA of known organisms.
While there was considerable variation of bacterial gut communities between animals, the study showed many of the same microbial genes were found in all of the digestive tracts, with differences in their relative abundance dependent on whether they were meat-eaters, vegetarians or omnivores. Among the mammals whose fecal material was used to sequence gut bacteria microbes included giraffe, bighorn sheep, gazelle, kangaroo, hyena, lion, polar bear, elephant, gorilla, baboon, black bear and squirrel.
The team also showed how diet influences microbial communities in the human gut by sampling 18 lean people who purposely had cut their caloric intake by 25 percent or more using many different dietary strategies. The researchers found that the functions of gut microbes varied according to how much protein the individuals ate, and the bacterial species varied according to how much fiber was consumed.
In a related 2009 study led by CU-Boulder’s Knight, researchers developed the first atlas of microbial diversity across the human body, charting wide variations in microbe populations from the forehead and feet to noses and navels of individuals. One goal of human bacterial studies is to find out what is normal for healthy people, which should provide a baseline for studies looking at human disease states, said Knight, who also is a fellow at CU’s Colorado Initiative for Molecular Biotechnology.
“If we can better understand this microbial variation, we may be able to begin searching for genetic biomarkers for disease,” said Knight. It might someday be possible to identify sites on the human body, including the gut, that would be amenable to microbial community transplants with either natural or engineered microbial systems that would be beneficial to the health of the host, he said.
“Because the human microbiome is much more variable than the human genome, and because it also is much easier to modify, it provides a much more logical starting point for personalized medicine,” he said.
The latest findings emphasize the need to sample humans across the globe with a variety of extreme lifestyles and diets, including hunter-gatherer groups, said the researchers. Such studies could provide insight into the limits of gut bacteria variation and the possibility that human microbes co-evolved with human bodies and cultures, shaping our physiological differences and environmental adaptations.
Members of Knight’s lab and their many collaborators are studying how the human microbiome — all of a person’s hereditary information — is assembled in different people and how it varies in conditions such as obesity, malnutrition and Crohn’s disease. In addition to financial support from HHMI, Knight also has been supported by National Institutes of Health funds to develop new computational tools to better understand the composition and dynamics of microbial communities.
The Science magazine study was supported by the NIH and the Crohn’s and Colitis Foundation of America.
