New research from UBC Okanagan revealed that non-invasive techniques can return vital gut health data from the mucus in our fecal matter.

New research from UBC Okanagan could make monitoring gut health easier and less painful by tapping into a common—yet often overlooked—source of information: the mucus in our digestive system that eventually becomes part of fecal matter.

Correct, what’s in our poop.

Biology researcher Dr. Kirk Bergstrom and master’s student Noah Fancy found a non-invasive technique to study MUC2, a critical gut protein,  from what we leave behind in the bathroom.

“MUC2 is like the silent star in our guts. It’s constantly working to protect us, and its proper functioning is crucial for our overall health,” Dr. Bergstrom says. “It was originally thought that you could only access this important molecule from biopsies or tissue removed via surgery—highly invasive and painful procedures.

“However, our study shows mucus is actually a part of our stool, meaning we can get at it painlessly and at levels we could not before. Anytime we can do analysis non-invasively, it’s a win.”

Clues to health can be found in unexpected places, and Dr. Bergstrom’s team found a way to study important gut health markers from fecal-adherent mucus—a term that, in simpler words, refers to the mucus attached to our stool. This mucus, typically ignored and flushed away, contains a trove of information about gut health.

MUC2, a glycoprotein with many sugar chains attached, forms a protective barrier in our intestines in the form of mucus, safeguarding our gut from harmful microbes and toxins and playing a crucial role in digestive health.

Understanding MUC2 better could lead to significant advancements in managing and preventing gut-related diseases, impacting the day-to-day wellbeing of millions.

“We can use these new methods to visualize mucus-microbiota interactions and how they go wrong in various diseases, like inflammatory bowel diseases and colon cancer,” Dr. Bergstrom notes.  “The sugars on the mucins also carry lots of information on the health status of the colon.”

Master of Science student Noah Fancy led the work, which was the result of a strong collaborative effort between the Bergstrom Lab and the chemistry labs of Dr. Wesley Zandberg and the biology labs of Dr. Sepideh Pakpour, Dr. Deanna Gibson and Dr. Sanjoy Ghosh, all at UBC Okanagan.

The work was funded in large part by the Weston Microbiota Foundation and the Canadian Foundation for Innovation.

This research appears in the Journal of Biological Chemistry.

As the world grapples with the pressing challenges of climate change, new research from UBC Okanagan emphasizes the critical role of grasslands in sustaining biodiversity, particularly for migrating species like the burrowing owl.

A recent study from Dr. Lilian P. Sales, a postdoctoral fellow working with Dr. Lael Parrott in UBCO’s Earth, Environmental and Geographic Sciences department, explored the burrowing owl and how it’s adapting to climate change. The iconic species might see its habitat expand toward northern latitudes due to changing climates; however, this expansion is contingent on the availability of its primary habitat, native grasslands.

“A key motivation for this is the preservation of the Okanagan grasslands,” says Dr. Sales. “Despite its low abundance, the burrowing owl is often used as a symbol for grassland preservation and serves as a cultural icon linking the land, its people and conservation efforts.”

The burrowing owl depends on grassland environments for nesting and breeding. The study, employing ecological niche models coupled with climate and soil data, projected that under specific high-emission climate change scenarios, the burrowing owl could expand its range three to 10-fold toward northern regions. However, nearly half of these newly suitable environments might lack grassland coverage, predominantly due to human activities like agriculture and urbanization.

This deficiency might hinder the establishment of breeding populations for the owl. Such discoveries underline the urgent need to prioritize the conservation of grasslands across western North America.

“Not only could these grasslands offer sanctuary to the burrowing owl, but they could also serve as pivotal habitats for many other species migrating from the south,” says Dr. Sales.

The researchers strongly advise that any land-use plans for the future should integrate strategies for protecting grassland habitats, which are well adapted to the conditions of our changing climate. Such foresight will ensure that these areas can be practical tools for regional climate adaptation and biodiversity preservation.

“In the Okanagan, conservation areas such as the South Okanagan Grasslands Protected Area and the proposed South Okanagan Similkameen National Park Reserve are critical parts of a strategy for ensuring our landscape can be resilient to climate change,” says Dr. Parrott. “As a climate adaptation strategy, local governments should strive to protect a connected network of grasslands and open habitats from Osoyoos to Vernon.”

A focused approach towards safeguarding grasslands, intertwined with targeted conservation initiatives for species like the burrowing owl and burrow-digging mammals, can potentially maintain the diversity of these unique ecosystems in our changing climate.

“While it’s tempting to label the burrowing owl as a climate change indicator, we lack sufficient data to do so confidently,” Dr. Sales says. “However, we can predict range expansions for grassland-dependent species, and they will need natural cover to thrive.”

Dr. Sales says she was especially invested in the research because it connected her with the Burrowing Owl Conservation Society of BC. The group was instrumental in helping the UBCO researchers give their work real-world context.

The research offers a broader perspective on biodiversity conservation, says Dr. Sales. Landscape management should evolve as species move and adjust their geographic ranges in response to changing climates. Holding onto historical species lists as benchmarks for ecosystem health might become obsolete given the rapid ecological changes expected this century, she says.

“Adopting a forward-thinking approach to conservation might be the key to safeguarding global biodiversity in an ever-changing world,” says Dr. Sales.

The study appears in the journal Science of the Total Environment.

After wildfire, the devastation to the landscape and communities is obvious and unforgettable.

And now, a UBC Okanagan researcher is taking a different look at fire-impacted areas. Dr. Alessandro Ielpi, an Assistant Professor in Geomorphology with UBCO’s Irving K. Barber Faculty of Science, recently published research examining how the record-setting 2017 Elephant Hill Fire affected the Bonaparte River near Cache Creek, BC.

The research was recently published in CATENA, and was developed in collaboration with his colleague and long-time friend Mathieu Lapôtre, an Assistant Professor in Earth and Planetary Sciences at Stanford University.

The wildfire started in July 2017 southwest of Ashcroft, rapidly growing northward. It eventually burned 192,000 hectares and destroyed more than 100 homes in two months.

“It takes a few years to gain a full picture of how a wildfire has impacted a river. It’s sort of like a fog of war slowly lifting,” says Dr. Ielpi. “The Bonaparte River’s watershed was significantly impacted by the Elephant Hill Fire—about half of the entire watershed was burned to some degree.”

Dr. Ielpi says it’s important to keep in mind the Bonaparte—with a watershed shy of 4,000 square kilometres in surface area—is not a huge river system compared to, say, the Fraser, Mackenzie or Yukon rivers.

“When you think of a wildfire that impacts 1,900 square kilometres, it is indeed enormous. But watersheds are typically much larger,” he explains. “If you look at the watershed of very large rivers, they are hundreds of thousands, sometimes millions of square kilometres. To put that in perspective, even the largest wildfire we have burning in Canada is like a drop in the bucket when you look at the dynamics of really large river systems we have here on the continent.”

“Watersheds such as the Bonaparte River’s represent a sweet spot between sizes large enough to host mature floodplains with farmlands and communities, and small enough to be significantly impacted by large wildfires. And even though wetlands and riverbanks may not have directly burned, barren soils from hillslopes started releasing higher amounts of sediment to the river once the stabilizing vegetation was gone.”

To track changes to riverbanks, the research team surveyed the Bonaparte River in 2019 and again in 2021, and collected a number of satellite and aerial images that depicted the channel at different times before and after the fire.

“It generally isn’t until two or three years later that you really start to see what’s happening,” he says. “And what we saw is that the channel expanded and widened in response to the addition of sediment from burnt slopes. And it also accelerated its pace of erosion—the speed at which it erodes banks and moves across the floodplain has accelerated substantially.”

The Bonaparte River has widened up to 130 per cent and the researchers estimate the erosion pace has increased by 230 per cent. People who live nearby, or depend on the river, especially farmers and Indigenous communities such as the Bonaparte First Nation, also noticed a change in spawning beds, an increase of river silt immediately after the fire and that the water was supercharged with sediment.

“We can’t say with certainty how long-lasting this change will be; rather, we expect—and hope—that it will recalibrate with time. But it’s still important for communities and planners to understand that in a five-year timeframe after a wildfire, rivers and floodplains continue to be affected.”

Dr. Ielpi says they cannot predict if this is going to take place at every river touched by a wildfire—as every river and fire are different—but the data they collected allowed them to develop a model to estimate the increase in sediment supply. They were able to document post-fire channel widening and accelerated migration, and provide first-hand evidence of major alterations in landscape dynamics at the watershed scale.

These findings, in turn, have implications for hydraulic engineering and hazard forecasting related to changes in river dynamics downstream of wildfire areas.

The data can also be used for other regions like the Amazon Basin and the Great Basin of the Western United States to help predict potential post-wildfire river movement, floodplain damage, flood threat and even how spawning channels are changing.

“By comparing pre- and post-fire estimates of sedimentation in the Bonaparte River’s watershed, our model ultimately provides evidence of a megafire inducing watershed-wide alterations in stream mobility and geometry,” he adds. “This is an exploratory paper, but I hope it’s one that makes people think about the complex and multifaceted repercussions of wildfires, even years down the road.”

Student orientation programs will be in full swing Monday as UBCO’s Create takes place as part of a welcome for students new to campus. Classes for the academic year begin Tuesday.

Next week, after an extraordinary few days in August, classes will resume for the fall at UBC Okanagan.

Students, faculty and staff are gearing up for a busy back-to-school period. More than 12,035 students are registered for classes this September and almost 3,200 are new to UBCO. Move-in day will continue as planned on Sunday, September 3 with more than 1,400 students arriving to move into their on-campus residences.

Create, the new-to-UBCO student orientation, takes place Monday, September 4 and all classes will begin as scheduled and in-person on Tuesday, September 5.

“This summer, more than ever, we have seen the strength, professionalism and values of the UBC Okanagan community on full display,” says Dr. Lesley Cormack, UBCO Principal and Deputy Vice-Chancellor. “When our campus was placed on evacuation order just two weeks ago, the campus rallied together to ensure everyone was able to leave the area quickly and safely. Through this adversity, we saw UBCO’s values as a compassionate community shine through once again—it’s something our incoming students can take pride and comfort in.”

As UBCO looks toward the beginning of a new term, Dr. Cormack also recognizes it has been a trying time for many people. The health and safety of all students, faculty and staff is paramount and UBCO’s Campus Operations and Risk Management team continues to communicate directly with the Central Okanagan Emergency Operations team.

“While classes will begin as planned and it’s clear that campus is safe to welcome students from across Canada and the world, we also acknowledge there are many people within our community still not able to return home. And we’ve all seen the devasting images of homes and properties lost to the wildfire,” she adds. “The arrival of our students to the region has always brought a renewed sense of vibrancy and of the limitless possibilities created by education. I know this will be true this year perhaps more than ever.”

She notes, that the UBCO community bonded as never before with many people reaching out to offer help and support for those who were placed on an evacuation order or alert.

“I continue to be impressed by the calibre and character of the people on this campus,” she adds. “When faced with adversity, we reached out and supported each other in ways that have truly amazed me.”

As the campus begins to get busy as students move in and classes begin, Dale Mullings, Associate Vice-President, Students says the university has many resources for students and help is available for those who may need it.

“We continue to prioritize the wellbeing of our students, whether they live on or off campus,” adds Mullings. “For example, we have a number of initiatives specific to our students and this year, due to the wildfire emergency, we initiated the student emergency fund to help those immediately affected by the wildfires, and an airport welcome booth with a complimentary shuttle Friday, September 1 through Monday, September 4.”

Wellness and Accessibility Services has expanded to provide a health clinic, counselling services, wellness education, disability services and a new multifaith Chaplaincy. Many other services that support the wellbeing of our students such as our on-campus and in-community recreation programs, safe walk program, security phones across campus, a student-led Emergency First Response Team and the 24-hour campus security patrols are also gearing up for the year ahead.

While classes begin next week, Dr. Cormack notes there will be accommodations for those who remain under evacuation orders and alerts and cancelled travel plans.

“We will continue to work closely with those affected by the Kelowna-area wildfires to ensure they have the flexibility they require to start the school year successfully.”

A valuable resource for people returning to the community is the UBCO Campus Alerts page and FAQ which can be found at: ok.ubc.ca/wildfire-response

Climbing caribou numbers in northeastern British Columbia prove that collaborations between Indigenous and colonial governments can reverse decades-long declines, but focus needs to shift to culturally meaningful recovery targets, a consortium of researchers and community members say in a new paper published this week in Science.

UBC Okanagan’s Dr. Clayton Lamb and West Moberly First Nation Chief Roland Willson co-lead the paper, Braiding Indigenous Rights and Endangered Species Law, alongside nine others for the influential journal.

“Abundance matters. There are many cases where endangered species laws have prevented extinction, but the warning signs of decline can appear long before the laws take effect. People who live and work on the land see these changes – we need to listen and act with them to prevent declines,” says Lamb, a biologist and MITACS postdoc in UBCO’s Irving K. Barber Faculty of Science. “There is a large gap between what the laws see as species recovery and what communities need for health, food security, and cultural well-being.”

The policy paper builds on collaborations between UBCO’s Lamb and Dr. Adam Ford, who have previously published research highlighting recovery efforts of the Klinse-Za caribou herd near the West Moberly and Saulteau First Nations. They also looked at evolving bison and salmon recovery efforts in North America.

Researchers heard stories from West Moberly Elders about a “sea of caribou” once looking like “bugs on the landscape,” but only 38 animals remained in 2013. Those numbers climbed to 115 a decade later thanks to interventions led by Indigenous groups. While these early signs of recovery are cause for immense celebration, the herd remains much smaller than historic levels.

“We need to move past a life support mentality for biodiversity,” says Ford, head of UBCO’s Wildlife Restoration Ecology Lab. “We must restore nature and the time-honoured ways people interact with the land.”

Canada and the United States have endangered species laws that are designed to recover species abundance to levels that will minimize the chance of extinction, but these recovery targets do not take into account culturally meaningful abundance or distributions of plants and animals, the authors say.

The paper highlights the current caribou count would only provide about three animals, or one meal per person, per year for Saulteau and West Moberly First Nations. The culturally significant count would require a herd of over 3,000 animals, an abundance more reflective of the historic “sea of caribou” level.

Naomi Owens-Beek, manager of Treaty Rights and Environmental Protection for Saulteau First Nation, contributed to the research and the policy paper.

She says the collaboration between Canadian and Indigenous leaders is essential to preserving traditional ways of life. Some Elders in the region have never tasted caribou, yet it was a staple of their ancestors and provided vital nutrition, material, spirituality, and a sense of place.

“We looked out at the land and thought, ‘What do these caribou need to be once again the great herds our Elders spoke about?’ We first reduced predation to make sure the caribou weren’t lost. Now we’re focusing on protecting and restoring habitat,” she says.

“Caribou habitat has long been mistreated, and now there’s so few caribou. These herds need space to thrive, and that’s why we’re working with the nations, the province of British Columbia and Canada, to heal these lands and increase the population so we can one day go back into the mountains and hunt caribou.”

The paper also examined efforts to restore salmon and bison habitat in North America. Chief Willson says each species shows modest signs of recovery, but that isn’t nearly the progress needed.

“Braiding Indigenous rights with laws protecting endangered species can enable nations to respect and safeguard the rights of Indigenous communities, curb the threat of species loss, and ultimately confer broad societal advantages,” he says.

New research from UBC Okanagan’s shows that resistance exercise temporarily reduced hunger-inducing hormones among breast-cancer survivors.

A new study by researchers from the University of British Columbia and the University of Colorado has found that weight-lifting may benefit appetite regulation and energy balance in breast cancer survivors.

The study, published in Appetite, involved 16 women who had completed treatment for hormone receptor-positive breast cancer within the past five years. On separate days, the women performed a single bout of resistance exercise, such as lifting weights, or sat quietly. The researchers measured their appetite sensations, appetite-related hormones and energy intake before and after each session.

The results showed that resistance exercise temporarily reduced hunger-inducing hormones and increased appetite-suppressing hormones compared to the sedentary condition.

Dr. Sarah Purcell, the study’s lead author and an investigator with the Centre for Chronic Disease Prevention and Management based at UBCO, said the findings suggest resistance exercise may help breast cancer survivors maintain healthy body weight and prevent obesity-related complications.

“Breast cancer survivors are often at increased risk of obesity,” she says. “We know that exercise can suppress appetite in people without previous cancer, at least in the short term, so we tested that in women with previous breast cancer who have low estrogen as part of their treatment. After a single bout of resistance exercise, we found some modest suggestions that exercise changes hormones to promote fullness and decrease hunger.”

About 80 per cent of people with breast cancer have estrogen receptor-positive cancer (ER-positive), and the standard of care after radiation or chemotherapy is five to 10 years of estrogen suppression.

Popular culture may portray cancer survivors as emaciated and lethargic, but weight gain—especially for women fighting breast cancer—can be as much of a worry.

“We think from experimental studies that estrogen is essential for appetite regulation and energy metabolism,” Purcell says.

Other studies have suggested that people with long-term estrogen suppression may increase their fat mass over the long term and decrease their muscle mass.

“We’re not sure what causes that. We also know that exercise can positively impact appetite in people without previous cancer, decreasing hunger or increasing satiety in certain conditions.”

Purcell said more research is needed to confirm the long-term effects of resistance exercise on breast cancer survivors’ appetite and energy intake and identify the optimal frequency, intensity and duration of activity for this group.

“It’s preliminary. People may not realize that exercise can promote appetite hormones in a way that would, at least theoretically, decrease later energy intake. We saw that a single bout of resistance exercise led to lower amounts of a hormone that promotes hunger—ghrelin—and higher amounts of a hormone that promotes satiety or fullness—peptide-yy.

“Again, the changes were modest, so we need to compare it to people without cancer, which we’re doing now.”

The National Institutes of Health supported the research, which appears in the latest issue of Appetite.

UBCO researchers isolated the genome for black root rot, a fungus killing cannabis plants in a licensed growing facility in the BC Kootenays. Here, healthy roots, left, are compared to those affected by black root rot.

A slippery black ooze, millions worth of cannabis plants and a ticking clock all contributed to one UBC Okanagan research team cracking the code of a potentially deadly fungus threatening the industry. New research from UBCO doctoral student Chris Dumigan indicates his team has identified and analyzed Berkeleyomyces rouxiae—more commonly known as black root rot—in a crop affecting a Canadian licensed producer in the Kootenays. A former classmate at the University of Guelph, Delaney Bray-Stone, emailed Dumigan for help. Bray-Stone, who would become a co-author of the research paper, needed help identifying a root-rot pathogen rapidly spreading through an aeroponic facility. “He contacted me and sent me some pictures of root rot. They tested it for every available cannabis pathogen, and everything was fine. But if you look at the pictures of the initial infection, they were not fine,” Dumigan said. “They had to wipe out a crop because it was killing all the plants, but they also had to shut down a wing of their facility and throw out a whole bunch of equipment. All the filters would form this thick, black sludge. Delaney still has nightmares about this thing because of how much stress it caused him.” Dumigan’s first challenge was reproducing black root rot in a lab to study, but conventional growing media didn’t work. He was able to find an alternative, carrot agar. “I think this is why it’s been missed in the industry because it’s difficult to culture; it’s pretty specific,” Dumigan said. “It almost needs fresh plant tissue that you convert into a media. But after I made this carrot agar, I returned the next day, and this black cell mass was growing on it that matched what I saw under a microscope.” The carrot agar allowed him to begin researching treatments. Commercial cannabis is unique because Canadian authorities tightly control conventional fungicides, so growers don’t have exhaustive options. “They’re using things like sulphur to control fungi or canola oil for insects. Some biological products were approved, but many were developed for other crops,” Dumigan said. Within his thesis, however, he identifies several species of bacteria that inhabit roots and secrete compounds that can kill certain fungi. “I’ve found several of them that kill this fungus, but none of this is published. It’s only a potential biocontrol, but they could be registered in Canada because it’s a certified organic option, not a conventional fungicide,” Dumigan said. That’s the next phase. Deyholos and Dumigan released the genome for other researchers to download and study. He’s also working on a sequence-based diagnostic test so labs can help other producers worldwide avoid the same issues. “This is science. To do something new, to discover something new, I don’t have an economic incentive in the cannabis industry. But I have a personal interest in pushing the boundaries of science.” The research appears in the journal Plant Disease.

New research from UBC Okanagan suggests that understanding gut microbiomes of immigrants is important to understanding how westernization is driving immune responses like IBD.

Indian immigrants and Indo-Canadians who adopt westernized dietary practices experience a greater risk of inflammatory bowel disease (IBD)—while supplements and probiotics often recommended may not provide the same benefits to certain demographics, new research from UBC Okanagan reveals.

Leah D’Aloisio, a Master of Science student in UBCO’s Department of Biology, and her thesis adviser, Dr. Deanna L. Gibson, worked in collaboration with colleagues from the UK and India to better understand the daily challenges experienced by Indians adapting to new cultures.

They’re currently investigating how westernization affects the gut microbiome and makes them more susceptible to IBD.

D’Aloisio’s research involves collecting stool samples from Indians living in India, Indian immigrants and Indo-Canadians. She analyzes their gut microbiome composition using DNA sequencing. She also collected additional data including dietary habits, lifestyle changes, health status and socioeconomic information.

When comparing the microbiomes of those living in India compared to Euro-Canadians, she’s found that the gut microbiomes in Indians are extremely different from Euro-Canadians.

“I really want people to understand the differences that exist in the human gut microbiome,” D’Aloisio says. “It looks drastically different depending on where you’re born and your overall lifestyle, so if you’re an immigrant here in Canada, think about that… And know that the research that led to creating these ‘gut health’ products you see marketed to you today is likely not representing you. Take time to rethink this before you spend your money. You don’t want to introduce a species into an ecosystem that is not meant to be there.”

According to D’Aloisio, her research has important implications for public health and clinical practice. She hopes that her findings will raise awareness about the influence of westernization on the gut microbiome and health outcomes of immigrant populations.

She also suggests that interventions such as dietary counselling, tailored probiotic supplementation and stress management may help prevent or treat IBD among Indian immigrants.

Dr. Gibson started this project thanks to funding from a UBC Killam research award that supported a sabbatical where she was able to collaborate with several high-profile research institutes in Kolkata and Manipal, India. Understanding the gut microbiomes of various populations outside of westernized countries is important to understanding how westernization is driving dysregulated immune responses like those in IBD.

Atmospheric balloons are important tools for gathering information high above the earth in zones where people wouldn’t survive unless they wear pressurized suits.

When Lake Country’s Nolan Koblischke heard the American government was shooting down balloons suspected of spying, he was more than a little curious. The George Elliot Secondary graduate has sent one of those balloons into the atmosphere himself as a student at UBC Okanagan.

Atmospheric balloons are important tools for gathering information high above the earth in zones where people wouldn’t survive unless they wear pressurized suits. Most balloons collect climate data through radios, cameras and satellite navigation equipment—and are incapable of spying.

Koblischke, a fourth-year physics student, and Leonardo Caffarello are part of a UBCO physics and engineering team that launched a balloon to the stratosphere from a space centre in the Swedish Arctic last fall. The team, sponsored by School of Engineering Professor Jonathan Holzman, launched the balloon for a physics experiment to observe cosmic rays.

Koblischke said many people might be surprised at just how much you can learn from a balloon.

What are scientists learning from these atmospheric balloons?

These atmospheric balloons are a powerful and versatile tool for scientific research and exploration. Our balloon was launched in collaboration with Canadian and European agencies, so we were joined by other university and government agency teams from different countries.

Each team flying on the balloon had a different research objective and experiment. For instance, an Italian team was testing solar panels in the upper atmosphere to be used on satellites, a German space agency team was studying stratospheric chemistry and a Hungarian team was testing radiation sensors. We even saw an experiment to carry a telescope for atmosphere-free observations of space. Besides these applications, most balloons are used for weather purposes.

Is this the first time your project has left the ground?

No, the group was originally formed a few years ago by Caffarello and competed against other university teams in the Canadian Stratospheric Balloon Experiment Design Challenge. The UBCO student-led project was one of two experiments selected to fly onboard a high-altitude research balloon launched by the Canadian Space Agency in August 2019. The balloon was airborne at about 120,000 feet for 10 hours.

The project was working on a cosmic ray detection system and they were looking for different cosmic particles across the lower atmosphere. Caffarello has since graduated but led our team on the latest iteration of this experiment that took place in Sweden last fall.

Can you explain what you learned from the experiment last fall?

Our experiment was an innovative endeavour to detect cosmic rays in the stratosphere that Caffarello and I launched from the Esrange Space Center above the arctic circle in Sweden. We learned how to devise and construct an experiment that can withstand the severe conditions of near vacuum and extreme temperatures. We also gathered valuable data during the flight such as temperatures, pressure and images that proved that certain components of our experiment could work. Lastly, we realized that research requires perseverance and collaboration.

One of the most challenging moments was when we found an issue while preparing for the launch, a sudden failure during a pressure test. We worked until 4 am for three nights in a row, culminating in an all-nighter, to brainstorm solutions and design parts on the spot. Although we did not fully fix the problem, we remained resilient and worked diligently to resolve what we could and we were successfully approved for launch.

Cosmic rays sound dangerous

Cosmic rays can cause cancer by damaging DNA, but the chances are very small so you don’t need to lose sleep over it. Thankfully, our atmosphere blocks most of the highest energy cosmic rays, hence why we needed a balloon to get our experiment above much of the atmosphere, to try to detect more cosmic rays. You might have heard that you receive radiation when flying equivalent to a chest x-ray—cosmic rays are the reasons why.

What’s next for students at UBCO? Any more high-flying projects?

Yes, we have a student team called the UBCO StratoNeers who are currently participating in the Canadian Stratospheric Balloon Experiment Design Challenge. It’s the same competition Caffarello participated in back in 2019

The StratoNeers are testing hardware protective techniques to mitigate the occurrence of bit flips due to cosmic radiation in computer binary code. This experiment would provide new insights into protective techniques to safely store data onboard satellites, rovers and space telescopes.

Do you worry someone will shoot down your balloons?

We weren’t worried about our balloon being shot down. It did drift into Norway but thankfully the Norwegians didn’t mind.
