CU-Boulder Leeds School Confident
Apr 9th
Colorado business leaders confidence remains positive and has increased slightly going into the second quarter of 2014, according to the most recent Leeds Business Confidence Index, or LBCI, released today by the University of Colorado Boulder’s Leeds School of Business.
The second quarter LBCI posted a reading of 61, an increase from 59.9 last quarter. Expectations measured positive — at 50 or higher — for all of the metrics measured by the index, which include the national economy, state economy, industry sales, industry profits, capital expenditures and hiring plans.
The across-the-board positive standings represent 10 consecutive quarters of positive expectations, according to the Leeds School’s Business Research Division, which conducts the LBCI — a report that’s now in its 10th year.

CU alumnus heading to the International Space Station
Mar 20th
University of Colorado Boulder alumnus and NASA astronaut Steve Swanson will blast off with two Russian crewmates for the International Space Station March 25, his third mission to the orbiting facility.
But this time he will not be riding in the familiar confines of a NASA space shuttle — the fleet was retired in 2011 — but in a capsule atop a Soyuz TMA-12 rocket launching from the Baikonur Cosmodrome in Kazakhstan. Not only will he blast off from there, he is slated to land in the capsule, which is somewhat similar to a NASA Apollo capsule, on the steppe of Kazakhstan in September after spending roughly six months in space.
Former CU student Steve Swanson eads to the International Space Station for the third time.
Swanson, who earned a bachelor’s degree in engineering physics from CU-Boulder in 1983, will serve as flight engineer for Expedition 39, which already will be underway on the ISS when he arrives. In late May, Swanson, who considers Steamboat Springs, Colo., his hometown, will become space station commander as Expedition 40 begins.
Swanson will be launched to the ISS along with cosmonauts Alexander Skvortsov and Oleg Artemyev of the Russian Federal Space Agency.
“We’ve trained extensively and I’m confident I can do all of the tasks assigned to me on the space station,” Swanson said. “The difficult part is being away from my family and friends for a long period. I’ll miss them, but at the same time we will be very busy up there, which makes the time pass quickly.”
The astronaut crew will be involved in dozens of research experiments in the low gravity of the ISS, including efforts related to protein crystal growth, capillary blood flow, gravity sensing by plants and muscle and bone loss changes in space.
As part of his duties, Swanson will operate hardware developed by BioServe Space Technologies located in CU-Boulder’s aerospace engineering department to conduct two experiments on the space station, both being launched later this year. One led by Dr. Timothy Hammond of the Department of Veterans Affairs will use a yeast-based assay system to evaluate known and novel anti-cancer drug therapies in the low gravity of space. A second led by Professor Cheryl Nickerson of Arizona State University will evaluate host-pathogen interactions to better understand the risk of in-flight infections by space explorers during long-term missions.
Swanson previously flew on the STS-17 mission aboard the space shuttle Atlantis to the ISS in June 2007, then flew again on the STS-19 mission aboard Discovery in March 2009. Swanson spacewalked for more than 26 hours during the two missions and is tentatively slated for two more spacewalks during Expedition 39 and Expedition 40.
What does Swanson, whose two shuttle landings were on a smooth NASA runway in Florida, think about drifting by parachute in the Soyuz space capsule on the way from the space station back to Earth, eventually banging onto the ground in Kazakhstan? “I know this landing will be much more wild and exciting than a shuttle landing,” he said. “It is going to be a very different experience, and I’m looking forward to it.”
Swanson will be packing several CU mementos, including a T-shirt, a flag and a small piece of sandstone from the engineering center that has been engraved with a picture of Ralphie the Buffalo and an image of the International Space Station.
What does he recall about his time at CU-Boulder? “I remember waking up and seeing the mountains right there,” he said. “It was a beautiful thing, and helped me get going every day. I really liked CU-Boulder — it is a good school, with good professors — and I love to ski, I love to hike. I like the culture.”
His favorite times on the space station? “One of the best things is when you have a moment to yourself where you can just look out the window,” he said. Swanson also said he will spend what little free time he has emailing with family and friends back on Earth, blogging about his space station experiences and hopefully participating in a Google Hangout, sharing messages and photos and video-chatting with CU-Boulder students.
Eighteen CU-Boulder astronaut-affiliates have flown 47 NASA space missions beginning with Scott Carpenter in 1962.
Former NASA astronaut Jim Voss, who received his master’s degree in aerospace engineering sciences from CU-Boulder in 1974, currently is a CU-Boulder Scholar in Residence. Former NASA astronaut Joe Tanner currently is a senior instructor in aerospace engineering.

Palm oil production a source of heat-trapping methane

Methane leaks from palm oil wastewater
are a climate concern, CU-Boulder study says
are a climate concern, CU-Boulder study says
In recent years, palm oil production has come under fire from environmentalists concerned about the deforestation of land in the tropics to make way for new palm plantations. Now there is a new reason to be concerned about palm oil’s environmental impact, according to researchers at the University of Colorado Boulder.
An analysis published Feb. 26 in the journal Nature Climate Change shows that the wastewater produced during the processing of palm oil is a significant source of heat-trapping methane in the atmosphere. But the researchers also present a possible solution: capturing the methane and using it as a renewable energy source.
The methane bubbling up from a single palm oil wastewater lagoon during a year is roughly equivalent to the emissions from 22,000 passenger vehicles in the United States, the analysis found. This year, global methane emissions from palm oil wastewater are expected to equal 30 percent of all fossil fuel emissions from Indonesia, where widespread deforestation for palm oil production has endangered orangutans.
The methane bubbling up from a single palm oil wastewater lagoon during a year is roughly equivalent to the emissions from 22,000 passenger vehicles in the United States, the analysis found.
“This is a largely overlooked dimension of palm oil’s environmental problems,” said lead author Philip Taylor, a postdoctoral researcher at CU-Boulder’s Institute of Arctic and Alpine Research (INSTAAR). “The industry has become a poster child for agriculture’s downsides, but capturing wastewater methane leaks for energy would be a step in the right direction.”
The global demand for palm oil has spiked in recent years as processed food manufacturers have sought an alternative to trans fats.
For now, the carbon footprint of cutting down forests to make way for palm plantations dwarfs the greenhouse gases coming from the wastewater lagoons. But while deforestation is expected to slow as the focus shifts to more intensive agriculture on existing plantations, the emissions from wastewater lagoons will continue unabated as long as palm oil is produced, the researchers said.
However, the climate impact of the leaking methane could be mitigated by capturing the gas and using it to fuel power plants. Biogas technology has been used successfully for decades and it can produce renewable electricity at a cost that’s competitive with traditional fuels, the authors said.
The amount of methane biogas that went uncollected from palm oil wastewater lagoons last year alone could have met a quarter of Malaysia’s electricity needs. Tapping into that unused fuel supply could yield both financial and environmental benefits, the authors said.
Capturing methane at wastewater lagoons could be encouraged by making it a requirement before palm oil products can be certified as sustainable, the authors said. Current sustainability certifications do not address wastewater emissions.
Taylor, whose research typically focuses on carbon cycling in old-growth tropical forests, was inspired to do the analysis by undergraduate researcher Hana Fancher, who also is a co-author of the journal article. Fancher and Taylor were doing research in Costa Rica, where palm oil production is spreading, when Fancher became curious about how the oil was being processed.
“She has a wastewater background,” Taylor said. “She ended up doing an honors thesis on palm oil agriculture and wastewater emissions. This paper is an extension of that thinking.”
Other co-authors from CU-Boulder include Associate Professor Diana Nemergut, doctoral student Samantha Weintraub and Professor Alan Townsend, in whose lab the work was based. Other co-authors include Cory Cleveland of the University of Montana, William Wieder of the National Center for Atmospheric Research and Teresa Bilinski of St. Edwards University.
