Aubrey Funke, the Assistant Director of the Imaging and Histology Core Facility (IHCF), welcomed the iCREATE students to the IHCF to learn how to use an extremely powerful (and extremely expensive) microscope! The Scanning Electron Microscope (SEM) can magnify 1,000,000 times - which is 1,000 better than a light microscope, which is already 1,000 time better than our eyes!
The Imaging and Histology Core Facility provides imaging services to faculty, undergraduate and graduate students, along with industry partners. They provide services in light microscopy, electron microscopy, and histology (microscopy of tissues).
Graduate Student Alyssa Talbert creates scaffolds for wound healing with elastin, collagen and water in her graduate work. But here, she is illustrating how to collect and stain cheek samples for the students to view under the light microscope.
Alyssa and Aubrey then take the students to compare the digital light microscope images with the detail they can see with the SEM. Because electrons have a very small wavelength, much smaller than the wavelength of light, the resolution using the SEM is much greater than that of light microscopes.
Aubrey and Alyssa shared a variety of SEM images with the students, from insects (see past Ugly Bug Contest winners below), to fungi, Alyssa's scaffolds, and much more!
The students spent approximately 8 hours at the IHCF learning how to use the SEM. They took copious notes they then followed explicitly, with Aubrey observing them, and they were able to run the SEM themselves on their last day of the training!
Thank you to both Alyssa and Aubrey for all the time and patient effort they put into instructing the students on the SEM. We weren't surprised to learn that Aubrey won the "Outstanding Staff Member" for NAU's Biology Department at their award ceremony on Wednesday, May 2nd. Congratulations to Aubrey!
As stated on their website: The Ancient DNA Lab provides support for researchers working with ancient, historical, forensic, or other sensitive (low DNA quantity/quality) genetic samples. Established by the School of Forestry’s Carol Chambers and Faith Walker in 2016, the Ancient DNA Lab is physically isolated from other genetics labs on campus and adheres to rigorous quality control measures to prevent contamination, both of which are internationally recognized standards for the early stages of ancient DNA handling and processing.
The Ancient DNA Lab is sterilized (left) and ready to use in 2018.
The 2017 iCREATE class (right) was able to go into the lab between cleanings.
Some of the projects the lab has been involved with include a 10,000 year old bat, research using both extant (living) bats and bat guano, the 8,500 year old bison (below), and work with extant wombats in Australia.
Undergraduate Research Assistant Sam Hershauer presented some basic information on how DNA is extracted, amplified and analyzed in the aDNA Lab. Sam is working on collaborative research project on DNA from organisms in Alaskan lake sediments going back thousands of years. This collaborative project is with the Arctic Lakes Project headed by Dr's. Nick McKay and Darrell Kaufman in the School of Earth Sciences and Sustainability.
Thank you to Faith, Colin and Sam for sharing your hidden treasure with the iCREATE students!

Every student enrolled in our CAVIAT programs has the opportunity to participate in a Career and Technical Student Organization (CTSO). These organizations provide scholarships, competitions, leadership opportunities and so much more that enriches the life and learning of our students.
Some of our students are traveling to the Arizona state competition hosted by the CTSO, HOSA - Future Health Professionals. HOSA is an international organization focused on developing character and technical skill competencies for members, to uplift current and future people in the health professions.
Our students are there to compete in a variety of subject matters. Madison Stump, of the Medical Professions program, is competing in the Behavioral Health event. Cylie John, also in the Medical Professions program, is taking the Medical Law and Ethics test. Dakota Palmer, of the Veterinary Assistant program, is doing the Veterinary Science skills test. Zachary Ashland and Elizabeth Strones, from the Bioscience program, are both taking part in the Medical Innovation event, and their classmate Antonia Green is taking the Biomedical Laboratory Sciences test.
To qualify for this week's state competition, students took an online test which covered a wide variety of topics from their program's curriculum. Only top scoring students are allowed to attend the state competition and earn the chance to move on to the international competition at the International Leadership Conference, which takes place at the end of June.
The state competition this year is taking place in Tucson, from April 2nd through April 4th. Let's cheer them all on to victory!
And not to be left out of the fun, this week our Fashion Design and Merchandising program is headed off to Los Angeles! They're going to visit the Fashion Institute of Design & Merchandising and the LA fashion district. They've been fundraising for this trip all year, and all the hard work has finally paid off.
Eleven high school students in the CAVIAT iCREATE bioscience class publicly presented their unique solutions to the authentic problem of tracking and reporting influenza-like illnesses in Coconino County. The presentations were held on March 7th at NAU's Center for Science Teaching and Learning. The students are in the second semester of this college-level course that earns credits from both Coconino Community College plus from Coconino High School or Flagstaff High School. The class meets after school for 2.5 hours each day from Monday to Thursday to learn the CTE (career and technical education) bioscience standards through an epidemiologic lens and with rich community involvement. Community partners include Coconino County Public Health Services District, North Country HealthCare, Northern Arizona Area Health Education Center, Northern Arizona Healthcare and TGen North. The students also gained assistance from Corryn Smith in using GIS technology for their reports.
Instructors Dr. Aaron Tabor and Robert (Bobby) Woodruff co-teach the class at NAU. Both have extensive experience in research and education. They also include additional community partners for in-class presentations and field trips. Students have toured the Science and Health Building at NAU, the Center for Ecosystem Science and Society (ECOSS) laboratories, the Clinical and Pathology Laboratory at Flagstaff Medical Center, and more!
The students study disease-causing agents as then use the tools necessary to determine what microbes cause the illnesses. The class includes biosafety skills, microbiology techniques, DNA extraction, separation and analysis. Students take an end-of-year test to demonstrate their knowledge and skills.
Congratulations to all the students! And thank you to the community members that attended their presentations! NAU Provost and Vice President for Academic Affairs Dan Kain (Left), FUSD Assistant Superintendent for Curriculum and Instruction Mary K Walton (Center), and FUSD Superintendent Mike Penca (Right), all came to hear the student presentations and ask them questions about their unique solutions to this authentic community problem.
Melissa (Lissy) Enright, a graduate student in ECOSS at NAU, shared her research on the hydraulics (water movement) of giant redwood trees with the high school students in the iCREATE class at NAU.
Lissy shared some of her background with the students including working on an oceanographic vessel with the Sea Education Association, working for the National Park Service in Hawaii, and for American Conservation Experience as an AmeriCorps Member in both Flagstaff and Alaska! She also worked with Honko, an NGO (non-governmental organization) working in partnership with the coastal communities of Madagascar on mangrove conservation. She showed the students the website for the Student Conservation Association where you can search through their list of opportunities, including those for students under 18 years old!
Lissy's experience helped her to get a "real job" working with the US Forest Service in Alaska doing a Forest Inventory and Assessment. She also worked in Northern California where she now has her research area studying water stress at the top of Redwood trees.
Lissy illustrated how the stems of the tree branches can get embolisms (air bubbles) from high water stress. She climbs the trees using a jumar system and then brings the branches home to Flagstaff to study the hydraulic conductivity of the tree.
Lissy asked the students why the pine needles and branches might be ore water stressed at the top of the trees than down below. Even though the base of the redwood is in an often moist environment, the tops of the trees are more exposed to sun; but the primary reason is that water is pulled all the way up the xylem (water tubes) of the tree from the ground to 250-400 feet! So the top of the tree is more like a dry climate.
Lissy took the students into the laboratory where she measures the hydraulic conductivity of the branches. She had them assist her with several experimental procedures she uses to determine levels of water stress in the redwood trees.
She told us: We measure hydraulic conductivity on the hydraulic line, a system of tubes that connects a stem segment to an upstream reservoir of solution (water with a tiny bit of potassium chloride)suspended a meter above the sample, and a downstream balance. The water flowing through the sample is measured as it gets to the balance. We use this measurement to infer about the degree of embolism, or air bubbles blocking the flow of water, present in the xylem cells. If the conductivity is very low, for example, we presume that there are a lot of embolisms, and the tree the sample came from was subject to a lot of water stress.
In the image above, a student measures pressure for another experiment. Lissy explains: When a piece of a plant is clipped off, the water inside sucks back away from the cut surface. This is because there is tension in the water in plants. If the plant is more water stressed, the tension is greater. We can measure this in units of pressure with a pressure chamber. We first cut a sample, then insert it into the chamber with the cut end extending out of the hole in the top. When we turn up the pressure in the chamber, the water will be forced back to the cut surface. We measure the pressure at which the water reaches the surface, and know that that number is equal to the tension that existed in the water in the plant before we cut it. If it takes a lot of pressure, then the plant was very water stressed.
Thank you, Lissy, for the wonderful presentation and the engaging hands-on research in your lab!

CCC CAVIAT Students Focus on Health Professions
They’re taking college classes, but they’re still in high school. Not only that, but they’ve proved their mettle in problem solving in the health occupations, and they’re on their way to a statewide competition in April.
Twelve students in Coconino Community College’s Dual Enrollment/CAVIAT BIO 298 class took exams on Creative Problem Solving through Health Occupation Students of America (HOSA). This class is taught by CCC Science Faculty and Bridges to Baccalaureate Principal Investigator Dr. Aaron Tabor, NAU Graduate Students and CCC Instructors Christina Baze and Bobby Woodruff.
“Four of the students qualified to go to the state level,” Tabor said, adding that all of the students are equally intelligent and deserving of accolades. The team placed ninth overall.
The four students, all 10th graders, are Cate Cole and Ethan Perelstein from Flagstaff Arts and Leadership Academy; and Kaleb Herrelko and Jacqueline Slack from Coconino High School.
According to information from HOSA, its mission is to “promote career opportunities in the health care industry and to enhance the deliver of quality health care to all people.” The focus is on health science education and biomedical science programs to promote interest in pursuing careers in the health professions.
To prepare for the exams, Slack said that the team began by reading books on creative problem solving and by researching various health-related problems in the community. Cole added that the team tested one another with problems as well as timing the testing for solutions.
During testing, the team had 30 minutes to prepare and had 8 minutes to present their case in front of a panel to judge. They made the grade, and now they’re heading to Tucson for the statewide competition.
“I personally am excited to meet other students like us, who are science minded,” Perelstein said.
Herrelko added, “That could be fun.”
Slack said, “I’m very excited to compete.”
Cole said, “I’m really excited to see what we can come up with – real-world problems that affect millions across the globe.”
The team members are part of the iCREATE High School Bioscience program. The class offers six credit hours from CCC to apply to a college degree. The students meet five days a week at the Center for Teaching and Learning at Northern Arizona University for lectures and labs. The program is offered through the Coconino Association for Vocations, Industry and Technology.
“I love coming here and getting a taste of what college and medical school will offer,” Cole said.
Perelstein said, “For me, this class is challenging, it’s engaging, and that’s what I really love.”
Herrelko said, “I like the challenge and it requires more persistence.”
Slack said, “I’m excited that every day after school, I get to be around science-oriented, like-minded people.”
For Tabor, he said he thoroughly enjoys being the instructor for the class.
“Frankly, it’s the students,” he said. “I never in a thousand years anticipated teaching K-12 students at all, but this group of students is one of the best I’ve ever encountered.”
Tabor added that his job is to educate the students on the translational sciences and the epidemiology field, but he also is to assist them with their professional growth – creating curriculum vitaes, attending conferences, performing public speaking, seeking publication, and more.
As for the state competition in April, Tabor said the students can go to the national level in the event if they are rank high enough for it. So, the journey may not be over for one or several of them after the state competition.
And as for the future, all four team members have plans. Cole’s goal is to become a physician, an obstetrician. Perelstein is interested in mechanical engineering, particularly “biomimicry,” or solving problems through evolutionary processes. Herrelko is still exploring, but he knows he wants to be an engineer of some sort. Slack is dedicated to becoming a neurosurgeon.
“We challenge one another and work to put our best foot forward as a team,” Perelstein said.
The iCREATE HS Bioscience program is funded by a grant from the National Science Foundation. Community partners include CCC, CAVIAT, NAU, TGen North, North Country HealthCare, Coconino County Public Health Services District, and Flagstaff STEM City.

By Dave Engelthaler, Associate Professor at the Translational Genomics Research Institute and the Chair of the Northern Arizona Leadership Alliance. This column was adapted from the keynote speech, given by the author, at Science Foundation Arizona's "Giving a Voice to STEM" Conference at NAU on September 30, 2016.
I have often referred to Flagstaff as the Shining City on Arizona’s Hill. It is no accident that I borrow this phrase from the famous, precisely American, ideal of a “Shining City on a Hill”. The early pilgrims imagined that they could create such a community for themselves after escaping the historical norms of European controls on destiny.
Three hundred years later John F. Kennedy reminded of this founding ideal, stating that the world was watching our shining city and that we must live up to our promise; shortly there after, we embarked on one of the greatest journeys of all time and put a man’s foot on the moon (Flagstaff had something to do with that, more on that below).
Twenty years later, Ronald Reagan again reminded us of this American City on a Hill ideal; and while we may not often remember Reagan as a champion of science, he was convinced during his tenure to not only not cut the budget of the National Science Foundation, but rather double it, before he left office. But, as under Kennedy and Reagan and other presidents in before and after, no matter what our economic and cultural condition, we have always led the way in advancing humanity through the sciences.
It is this ideal that convinces me that in Flagstaff, we are a Shining STEM City on Arizona’s Hill.
In August of 2012, a group of Flagstaff Leaders, Businessmen, Educators, Scientists, and Concerned Citizens gathered in the woods on the base of the San Francisco Peaks. This group coalesced around the idea that Flagstaff is a STEM-rich City and that we as a community, businesses and schools, elected leaders and CEOs, teachers and families, needed to collectively band together to bring this rich surrounding to bear on the education of our children and enrich our communities.
There, up on our Hillside, we all mutually pledged our time, talent and resources towards making the STEM City ideals happen. In short – our goal was to have the most STEM literate graduates living and working in a thriving STEM-based economy.
We also had a unofficial motto for the day: “Dare Mighty Things”, which we borrowed from the Jet Propulsion Laboratory, who had, just the preceding night, coordinated the landing of the Curiosity Rover on Mars (and again, Flagstaff had something to do with this mission). And we both stole that from Teddy Roosevelt’s famous “Far better it is to dare mighty things” speech.
Historian, Fredrick Jackson Turner, just a few years before TR’s famous speech, gave us his “Frontier Thesis”, and proclaiming that with the end of the American Frontier, so might be the end the American spirit. While Jackson aptly, and controversially, linked Americanism and American spirit to the discovery and exploration of the American Frontier, I feel that he missed the mark in not understanding the new frontiers that we would identify and explore.
Our increased understanding and use of science and engineering opened up brand new frontiers, beyond land and sea.
One such Frontier, The Space Frontier, was no longer a pastoral landscape to watch from afar. Our STEM City has been at the forefront of the exploration of this new frontier, from the discovery of Pluto, to the training of Apollo astronauts in our backyard, to the camera control of the Mars Rover from our USGS facility, and now finally to the deep space explorations through our Discovery Channel telescope, providing insight into the beginnings of our universe and images of a frontier previously unseen.
Likewise, Flagstaff is home to TGen and the new Pathogen and Microbiome Institute at NAU, where some of the brightest minds are exploring another previously unseen universe – the microbiome. Every day, scientists in Flagstaff are embarking on the incredible journey into the human microbiome – the unseen ecosystem of bacteria and viruses and fungi that live on and in the human body. We are trying to understand how these microbes live, compete, collaborate and otherwise interact during our healthy and disease states. We, ourselves, our bodies, are the new frontier – and again that frontier exploration is here in our STEM City.
And we could go on about the new frontiers ventured by W.L.Gore engineers and SenesTech scientists and MNA paleontologists and Park Service geologists. The frontier is here in our STEM City and some of the greatest pioneers are the trainers of our next generation– the teachers and education professionals of our great public, charter and private schools. Most are ready, willing and able to interact with all of these resources; and some, like former STEM City Teacher of the Year Jillian Worssam, just kick down the door and say: “Let’s do this thing!”
Our STEM City is Worssam’s wildly successful Scientists in the Classroom. It is the Flagstaff Festival of Science (the longest running one in the country). We are the Coconuts; we are the Annual STEMMY'S Awards Ceremony; the STEM Art Competition; and the Super Bowl of STEM in the Dome event (where upwards of 8% of Flagstaff turns out!); we are the Space Station Science Experiment and the High Altitude Balloon Launches; and the superstar Killip Kindergarten Chess team that likes to challenge our Mayor. We are seventh-grade girls wearing lab coats inside a world-class research lab and we are a group of high schoolers rafting down our majestic Canyon to learn our geologic past. We are the Chamber Coding Camps. We are grad students teaching and learning in the K-12 classroom. We are parents, students and teachers on a hill having a star party. We are, in a phrase, America’s First STEM Community.
Arizona, and the rest of the country, is watching our shining STEM City
and we must live up to our promise.
Guest blog by Carrie Jenkins and Rick Treadway, 7th grade science teachers at Sinagua Middle School
On April 11, 2016 a group of 48 Sinagua Middle School 7th graders headed into Oak Creek Canyon for an afternoon of water testing at Slide Rock State Park. After eating lunch at the park, we walked to the Apple Barn where we watched a short documentary about Oak Creek called “Loved to Death: The Story of Oak Creek.” The video documented the 2014 Oak Creek Ambassador Program in which concerned citizens with the support of local university students from U of A, NAU, ASU, and the Friends of Oak Creek, removed large quantities of trash brought into the park and along the creek.
Oak Creek is claimed to be the 3rd purest water in the world at its source. However, the trash left behind by the hundreds of thousands of visitors each year directly impacts the water quality of Oak Creek and leads to increased levels of e. coli causing adverse effects to the local ecosystem. Under the direction of U of A microbiologists in a mobile laboratory the students tested E.coli bacteria levels, water flow rates, pH, turbidity, nitrates and dissolved oxygen. Students learned proper water sampling protocol, testing procedures and levels that indicate healthy conditions for organisms within the aquatic ecosystem. Most importantly, we learned that we can each be an ambassador for Oak Creek.
Thank you to the SFAz+8 Pathways grant through Coconino Community College for funding the bus for this fieldtrip!
Superbowl of STEM
The 3rd Annual Flagstaff Community STEM Celebration kicked off the week on Monday, March 7th at the NAU Skydome with almost every school, STEM business, government agency, and non-profit in Flagstaff! You can relive the excitement with Flg4TV's 2 minute video here!
High-Altitude Balloon Launch
On Wednesday, March 9th, Teacher Kaci Heins and 100 NPA 6th graders sent their payload to over 106,000 feet on a high-altitude balloon from the Flagstaff Airport. Community Leader Bruce Sidlinger and his Aeronautics Engineering class from Flag High, Airport Director Barney Helmick, the Coconino Amateur Radio Club, the Civil Air Patrol, and many other community partners were there to assist. You can see images and hear the story from KNAU's science and technology field reporter Melissa Sevigny here.
Women Executives in STEM Panel
NAU hosted the panel on Thursday, March 10th. All of the women had connections to NAU and facilitator Elizabeth Glass recommended that the many students in attendance use their alumni network as they search career opportunities.
AZ North Regional
The Skydome was brimming again on Friday and Saturday with the CocoNuts and 52 other teams, for NAU's inaugural FIRST Robotics Arizona North Regional contest, which pitted robots against each other to try to take down a castle. You can read Corina Vanek's article on the event here. Microchip sponsored pit tours by volunteers from many of the teams, as well as a VIP luncheon that was well-attended by Flagstaff's government, business, and education leaders. FIRST, which stands for --- , is a non-profit founded in 1989 by Dean Kamen, the inventor of the Segway. It encourages students to pursue STEM and also develops skills in teamwork, problem-solving, creativity, and gracious professionalism.
Congratulations to everyone on helping make STEM Week 2016 the best ever in Flagstaff STEM City!
