Boulder police: Serial bike theft suspect arrested
Mar 10th
Boulder Police detectives have been investigating a series of thefts of high-end bicycles from the downtown area and today, March 10, 2014, formally arrested the suspect, John William Samson III (DOB 10/04/1975). Samson was arrested at the Boulder County Jail, where he has been incarcerated on separate charges.
Samson faces 34 counts of Theft, one count of Third Degree Burglary, one count of Criminal Trespass and one count of Criminal Mischief. Twenty-nine of the charges are felonies.
Investigators believe Samson is responsible for the thefts of 43 bicycles from May 2013 until September 2013. The bikes are worth a total of approximately $147,000.00. The bicycles range in price from $700.00 to $9,000.00 each.
The majority of the thefts took place in the downtown business area during daylight hours. Most of the bikes were locked, either to bike racks or on vehicle racks. None of the stolen bikes have been recovered, and they have not shown up in area pawn shops.
Several bicycles were stolen from the campus of Boulder High School, including five bikes belonging to the Boulder High School’s mountain bike team. Those bicycles had been stored in a locked trailer and were taken during the Boulder flood.
Victims include local residents, people travelling through Colorado on vacation and at least one victim who had driven to Boulder for a bike competition, only to find his bicycle stolen the day before he was to compete. Victims are juveniles, students, professionals, a professor and an out-of-state fire fighter.
Brands of the stolen bikes include: Yeti, Santa Cruz, Transition, Titus, Felt, Scott, Specialized, Kona, Gary Fisher, Trek and Klein.
Samson is currently in jail, and his bond has been set at $100,000.00. Detectives are continuing to investigate.
The Boulder Police Department has been working in partnership with the Colorado Department of Corrections, which provided critical information and timely assistance during our investigation.
Anyone with information about these thefts is asked to contact Detective Craig Beckjord at 303-441-3336. Those who have information but wish to remain anonymous may contact the Northern Colorado Crime Stoppers at 1-800-222-TIPS (8477) or 1-800-444-3776. Tips can also be submitted through the Crime Stoppers website atwww.crimeshurt.com. Those submitting tips through Crime Stoppers that lead to the arrest and filing of charges on a suspect(s) may be eligible for a cash reward of up to $1,000 from Crime Stoppers.

CU-Boulder study: Spiral galaxies like Milky Way bigger than thought
Jun 27th
CU-Boulder Professor John Stocke, study leader, said new observations with Hubble’s $70 million Cosmic Origins Spectrograph, or COS, designed by CU-Boulder show that normal spiral galaxies are surrounded by halos of gas that can extend to over 1 million light-years in diameter. The current estimated diameter of the Milky Way, for example, is about 100,000 light-years. One light-year is roughly 6 trillion miles.
The material for galaxy halos detected by the CU-Boulder team originally was ejected from galaxies by exploding stars known as supernovae, a product of the star formation process, said Stocke of CU-Boulder’s astrophysical and planetary sciences department. “This gas is stored and then recycled through an extended galaxy halo, falling back onto the galaxies to reinvigorate a new generation of star formation,” he said. “In many ways this is the ‘missing link’ in galaxy evolution that we need to understand in detail in order to have a complete picture of the process.”
Stocke gave a presentation on the research June 27 at the University of Edinburgh’s Higgs Centre for Theoretical Physics in Scotland at a conference titled “Intergalactic Interactions.” The CU-Boulder research team also included professors Michael Shull and James Green and research associates Brian Keeney, Charles Danforth, David Syphers and Cynthia Froning, as well as University of Wisconsin-Madison Professor Blair Savage.
Building on earlier studies identifying oxygen-rich gas clouds around spiral galaxies by scientists at the Space Telescope Science Institute in Baltimore, the University of Massachusetts, Amherst College and the University of California, Santa Cruz, Stocke and his colleagues determined that such clouds contain almost as much mass as all the stars in their respective galaxies. “This was a big surprise,” said Stocke. “The new findings have significant consequences for how spiral galaxies change over time.”
In addition, the CU-Boulder team discovered giant reservoirs of gas estimated to be millions of degrees Fahrenheit that were enshrouding the spiral galaxies and halos under study. The halos of the spiral galaxies were relatively cool by comparison — just tens of thousands of degrees — said Stocke, also a member of CU-Boulder’s Center for Astrophysics and Space Astronomy, or CASA.
Shull, a professor in CU-Boulder’s astrophysical and planetary sciences department and a member of CASA, emphasized that the study of such “circumgalactic” gas is in its infancy. “But given the expected lifetime of COS on Hubble, perhaps another five years, it should be possible to confirm these early detections, elaborate on the results and scan other spiral galaxies in the universe,” he said.
Prior to the installation of COS on Hubble during NASA’s final servicing mission in May 2009, theoretical studies showed that spiral galaxies should possess about five times more gas than was being detected by astronomers. The new observations with the extremely sensitive COS are now much more in line with the theories, said Stocke.
The CU-Boulder team used distant quasars — the swirling centers of supermassive black holes — as “flashlights” to track ultraviolet light as it passed through the extended gas haloes of foreground galaxies, said Stocke. The light absorbed by the gas was broken down by the spectrograph, much like a prism does, into characteristic color “fingerprints” that revealed temperatures, densities, velocities, distances and chemical compositions of the gas clouds.
“This gas is way too diffuse to allow its detection by direct imaging, so spectroscopy is the way to go,” said Stocke. CU-Boulder’s Green led the design team for COS, which was built by Ball Aerospace & Technologies Corp. of Boulder for NASA.
While astronomers hope the Hubble Space Telescope keeps on chugging for years to come, there will be no more servicing missions. And the James Webb Space Telescope, touted to be Hubble’s successor beginning in late 2018, has no UV light-gathering capabilities, which will prevent astronomers from undertaking studies like those done with COS, said Green.
“Once Hubble ceases to function, we will lose the capability to study galaxy halos for perhaps a full generation of astronomers,” said Stocke. “But for now, we are fortunate to have both Hubble and its Cosmic Origins Spectrograph to help us answer some of the most pressing issues in cosmology.”
The study was supported by a NASA/Hubble Space Telescope contract to the Cosmic Origins Spectrograph science team, general NASA/Hubble Space Telescope observing grants to Stocke and a National Science Foundation grant to Keeney.

Leading quantitative conservation biologist named CU’s first Colorado Chair in Environmental Studies
Oct 1st
The endowed chair in environmental studies was made possible by $4 million in gifts made anonymously in 2009 and 2010 toward the chair.
Sharon Collinge, professor and director of the CU-Boulder Environmental Studies Program, called Doak a perfect match. “He epitomizes what we’re looking for,” she said.
Doak is especially skilled in interdisciplinary research, she said. He brings expertise in policy to his analyses of risks of energy development, for example. And he is widely cited for his research in quantitative conservation biology, which combines sophisticated computer modeling with varying policy scenarios to project changes in populations of rare species.
For instance, the Proceedings of the National Academies of Science recently published a study co-authored by Doak concluding that the California condor is chronically endangered by lead exposure from hunters’ spent ammunition.
While the free-flying condor population has risen in the last three decades, that increase has been achieved through captive breeding, monitoring and veterinary care, the study found. Meanwhile, the primary threat to the endangered bird — lead poisoning from bullets and shotgun shells lodged in carrion — has gone largely unmitigated, the study said.
Doak and his fellow researchers found no evidence that California’s 2008 partial ban on lead ammunition yielded any decrease in lead exposure and poisoning in condors.
Since 2007, Doak has served as a professor of zoology and physiology at the University of Wyoming. Previously, he was a faculty member at the University of California, Santa Cruz. His research has been funded by the National Science Foundation, U.S. Fish and Wildlife Service, U.S. Forest Service, California Department of Fish and Game and the U.S. Bureau of Land Management. Scholarly papers have cited his work more than 3,000 times since 1998.
Doak said he was drawn to CU-Boulder’s Environmental Studies Program because of its breadth, spanning disciplines ranging from biogeochemistry to political science to philosophy. This interdisciplinary focus is necessary to confront some of the world’s most intractable problems, Doak and Collinge said.
“That’s the only way we can really address and resolve some of the major environmental challenges that we face,” Collinge said.
Working with experts from a wide range of disciplines, Doak added, provides a motivation and opportunity “not once a year but every day to confront your own ignorance and thus to appreciate and learn new ideas and approaches.”
It is not that interdisciplinary work is always best, he added. “We need to train ourselves and our students to determine when the problem we are confronting requires an interdisciplinary approach. If you want to build a bridge that won’t fall down, you don’t need an interdisciplinary team. You need a good engineer.”
The critical question, he said, is the following: “Is this problem a nail that requires a hammer, or is this a problem that requires a lot of tools? And most environmental problems require an entire chest of tools and the different people who know how to use them.”
Collinge said students sometimes grasp this distinction better than professors do. “Students who are interested in the environment understand very deeply that they have to know something about politics and policies and how we make choices and why we make choices,” she said. “They’ve essentially pushed us, encouraged us to provide that broad and deep training for them.”
Of the donor’s gift, Collinge said, “This was incredibly generous. And we are really grateful.
“For me, it validates or speaks to the importance of what we’re doing,” she said. “With more than 1,000 undergraduate majors in environmental studies and 50 graduate students, enthusiasm was abundant even before the gift that enabled the endowed chair.”
