Space flight to test antibiotic’s effectiveness
Jan 3rd
education project on ants to space station
NASA Television will provide live coverage of the launch of Orbital Sciences Corp.’s commercial Cygnus spacecraft on Tuesday, Jan. 7 from NASA’s Wallops Flight Facility in Virginia, which will be carrying two University of Colorado Boulder payloads to the International Space Station.
The two CU-Boulder payloads — a biomedical antibiotic experiment and an educational K-12 experiment involving ant behavior in microgravity — are slated to be launched aboard Orbital Sciences Corp.’s Antares rocket at 11:55 a.m. MST. Both experiments were designed by BioServe Space Technologies, a NASA-funded center in CU-Boulder’s aerospace engineering sciences department.
The CU-Boulder biomedical experiment was designed to test the effectiveness of antibiotics in space. Past experiments by CU-Boulder and other institutions have shown bacterial susceptibility to antibiotics is significantly reduced during spaceflight, although the reason is not yet known, said CU-Boulder Associate Professor David Klaus, principal investigator on the project.
Klaus said the investigation will examine changes in the gene expression of the bacteria E. coli during exposure to different concentrations of antibiotics while in the microgravity environment of space. The hope is to locate particular genes that are key to resisting antibiotics, which could lead to improved testing on Earth as well as new drug targets or new approaches to understanding antibiotic resistance in certain diseases or infections, said Klaus.
“Previous studies carried out in microgravity have shown that bacteria are able to grow in what normally would be an inhibitory concentration of the antibiotic,” said Klaus. “This investigation is aimed at characterizing the genetic basis for this response in the weightless environment of space with the intent of applying any insight gained toward combating the increasing emergence of drug-resistant pathogens here on Earth.”
Co-investigators on the project include BioServe Director Louis Stodieck, a research professor in aerospace engineering, and Shawn Levy, a researcher at the HudsonAlpha Institute for Biotechnology in Huntsville, Ala. The research effort also involves CU-Boulder doctoral candidate Luis Zea.
Bacterial resistance to antibiotics kills 100,000 Americans every year and represents a roughly $20 billion expense to the U.S. government in excess health care costs, said Klaus. The experiments will be undertaken using spaceflight test tubes contained in the Commercial Generic Bioprocessing Apparatus, or CGBA, an automated, suitcase-sized incubator, all designed and built by BioServe.
The second experiment launching to ISS is known as Ants in Space, which examines foraging patterns based on the density of the common Pavement Ant, said BioServe Business Development Manager and Education Program Director Stefanie Countryman. “Past experiments by Professor Deborah Gordon, principal investigator on this project, have shown that some ant species have the ability to search areas collectively without individual communication. When ant densities are high, each ant thoroughly searches one small area in a circular, “random” walk, she said. When ant densities are low, each ant searches by walking in a relatively straight line, allowing it to cover more ground.
“Ants assess their own density at the rate at which they meet,” said Countryman, who said the eight individual ant habitats on ISS will be loaded with roughly 100 ants each. “The experiment examines whether in microgravity ants will use the rate at which they meet to assess density, and so use straighter paths in the larger habitat areas. The results will be compared to ground controls, which in this case will include ant habitats in hundreds of K-12 classrooms around the world.”
Countryman has previously directed BioServe K-12 education experiments involving the behavior of butterflies, ladybugs and spiders in space, reaching hundreds of thousands of students around the world in the past two decades. For the ant experiments, BioServe is partnering with the Baylor College of Medicine’s Center for Education Outreach, a longstanding BioServe partner that has developed the education curriculum guide for the experiment.
BioServe research partners on the ant project include Gordon of Stanford University and Associate Professor Michael Greene of the University of Colorado Denver. The experiment is sponsored by NASA’s National Lab Education Office as well as the Center for the Advancement of Science in Space, a nonprofit group headquartered in Cape Canaveral, Fla.
Teachers interested in participating in the ant experiments may contact Countryman at countrym@colorado.edu. More information on the project for teachers and students will be online beginning in mid-January at http://www.bioedonline.org.
The flight will be the first Cygnus resupply cargo mission launched to ISS by Orbital Sciences Corp. and follows the earlier, successful launch of a Cygnus demo flight to ISS that arrived at the orbiting station Oct. 22.
In the past 25 years, BioServe has designed, built and flown microgravity life science research experiments on more than 40 space missions. BioServe has a full suite of space flight hardware, both on ISS and on the ground, which supports its own research as well as research conducted by its customers and partners. Past BioServe partners include large and small pharmaceutical and biotechnology companies, universities and NASA-funded researchers.

Solar eruption could be like an attack on the Earth
Dec 9th
points up need for society to prepare
A massive ejection of material from the sun initially traveling at over 7 million miles per hour that narrowly missed Earth last year is an event solar scientists hope will open the eyes of policymakers regarding the impacts and mitigation of severe space weather, says a University of Colorado Boulder professor.
The coronal mass ejection, or CME, event was likely more powerful than the famous Carrington storm of 1859, when the sun blasted Earth’s atmosphere hard enough twice to light up the sky from the North Pole to Central America and allowed New Englanders to read their newspapers at night by aurora light, said CU-Boulder Professor Daniel Baker. Had it hit Earth, the July 2012 event likely would have created a technological disaster by short-circuiting satellites, power grids, ground communication equipment and even threatening the health of astronauts and aircraft crews, he said.
CMEs are part of solar storms and can send billions of tons of solar particles in the form of gas bubbles and magnetic fields off the sun’s surface and into space. The storm events essentially peel Earth’s magnetic field like an onion, allowing energetic solar wind particles to stream down the field lines to hit the atmosphere over the poles.
Fortunately, the 2012 solar explosion occurred on the far side of the rotating sun just a week after that area was pointed toward Earth, said Baker, a solar scientist and the director of CU-Boulder’s Laboratory for Atmospheric and Space Physics. But NASA’s STEREO-A, satellite that was flying ahead of the Earth as the planet orbited the sun, captured the event, including the intensity of the solar wind, the interplanetary magnetic field and a rain of solar energetic particles into space.
“My space weather colleagues believe that until we have an event that slams Earth and causes complete mayhem, policymakers are not going to pay attention,” he said. “The message we are trying to convey is that we made direct measurements of the 2012 event and saw the full consequences without going through a direct hit on our planet.”
Baker will give a presentation on the subject at the 46th Annual Fall Meeting of the American Geophysical Union held in San Francisco Dec. 9 to Dec. 13.
While typical coronal mass ejections from the sun take two or three days to reach Earth, the 2012 event traveled from the sun’s surface to Earth in just 18 hours. “The speed of this event was as fast or faster than anything that has been seen in the modern space age,” said Baker. The event not only had the most powerful CME ever recorded, but it would have triggered one of the strongest geomagnetic storms and the highest density of particle fluctuation ever seen in a typical solar cycle, which last roughly 11 years.
“We have proposed that the 2012 event be adopted as the best estimate of the worst case space weather scenario,” said Baker, who chaired a 2008 National Research Council committee that produced a report titled Severe Space Weather Events – Understanding Societal and Economic Impacts. “We argue that this extreme event should be immediately employed by the space weather community to model severe space weather effects on technological systems such as the electrical power grid.
“I liken it to war games — since we have the information about the event, let’s play it through our various models and see what happens,” Baker said. “If we do this, we would be a significant step closer to providing policymakers with real-world, concrete kinds of information that can be used to explore what would happen to various technologies on Earth and in orbit rather than waiting to be clobbered by a direct hit.”
Even though it occurred about 150 years ago, the Carrington storm was memorable from a natural beauty standpoint as well as its technological impacts, he said. The event disrupted telegraph communications — the Internet of the Victorian Age — around the world, sparking fires at telegraph offices that caused several deaths, he said.
A 1989 geomagnetic storm caused by a CME from a solar storm in March 1989 resulted in the collapse of Hydro-Quebec’s electricity transmission system, causing 6 million people to lose power for at least nine hours, said Baker. The auroras from the event could be seen as far south as Texas and Florida.
“The Carrington storm and the 2012 event show that extreme space weather events can happen even during a modest solar cycle like the one presently underway,” said Baker. “Rather than wait and pick up the pieces, we ought to take lessons from these events to prepare ourselves for inevitable future solar storms.”
