Cybersecurity curriculum to pilot in Arizona schools


September 4, 2019

The average cost of a single data breach is nearly $3.9 million. Globally, the cost of cybercrime is expected to top $2 trillion this year, according to Juniper Research. Yet across the U.S., cybersecurity jobs remain vacant as employers are unable to recruit qualified candidates. That’s just one reason a new cybersecurity curriculum is launching this fall in Arizona K–12 schools, allowing teachers the opportunity to expose their students to cybersecurity at an even younger age. 

Arizona State University Professor of Practice Kim Jones is passionate about the importance of exposing youth to cybersecurity to help build an interest in the field. Jones says there are currently over 300,000 unfilled jobs in cybersecurity. His passion resulted in a generous grant from ASU’s Women and Philanthropy to help prepare Arizona students to fill scores of vacant cybersecurity positions.

ASU’s Cybersecurity Education Consortium has been working in collaboration with the Center for the Future of Arizona and Jobs for the Future to build a cyber curriculum that will pilot this fall.

“We are particularly excited to collaborate with ASU to deliver additional curriculum in cybersecurity career exploration,” said Cindy Erwin-Hogberg, director of college and career pathways with the Center for the Future of Arizona. “The opportunities for quality, exciting and fulfilling jobs in this industry are tremendous; yet, cybersecurity is an area that is not well understood by students and families. This curriculum will enable teachers to build their own knowledge as they share these resources with students.”

Jobs for the Future is a non-profit 501 (c)(3) organization that established the Pathways to Prosperity Program to ensure more students have the opportunity to complete high school and move beyond. They have created the “Possible Futures” career exploration curriculum in various subject areas to provide middle school students with the opportunity to understand career options at an early age.

“There are so many reasons to get students thinking about their strengths, interests and passions early on in their development,” said Jonathan Payne, program manager at Jobs for the Future. “In the middle grades, students are making decisions about who they are, how they fit into the world, what they are interested in, as well as, what they are good at and what they aren’t, so it’s essential to help students see the variety of pathways that exist for them in their future to both close the achievement gap, but more importantly to close the aspiration gap. This has to be done in middle school because high school is just too late.”

Jobs for the Future deliberately focuses their “Possible Futures” curriculum on middle school students in an effort to reach students at an age when they are impressionable, and before they have committed to a specific track in high school. They have launched this program in several states, including California, New Mexico, Tennessee and Massachusetts and are currently working with the Center for the Future of Arizona on Year 2 of a pilot to reach Arizona classrooms with their curriculum this fall.

“JFF did not have a cybersecurity curriculum, and we were in the process of developing a cybersecurity curriculum for middle school/early high school students as part of a grant project,” said Trista Zobitz, program coordinator of the Cybersecurity Education Consortium. “This collaboration provides JFF with a cybersecurity curriculum to add to their ‘Possible Futures’ platform and serves as a vehicle for the CEC to reach area schools with cybersecurity content.”

The cybersecurity curriculum consists of 15 lessons covering topics ranging from digital citizenship and threat prevention to encryption and security and includes lessons focused on careers in cybersecurity, so students can connect their interests to specific cyber jobs.

“These decisions have a huge impact on the doors they open, and those they close. Some of the doors they close might close pathways to their possible futures as well,” Payne said. “Careers in cybersecurity abound and with huge growth forecasted in the next decade, it’s a good bet on a great future.”

The pilot program will reach 19 schools across the Phoenix metro area, plus schools in Tucson and Yuma. The Center for the Future of Arizona has trained and worked with 25 teachers who will be implementing the “Possible Futures” curriculum into their classes this fall, reaching over 1,000 students in Arizona alone.

“Our goal was to share cyber curriculum with as many schools as possible, and through this partnership, we will reach multiple states,” Zobitz said. “That is success!”

Kombucha culture

Microbial communities in fermented drink can teach us about cooperation and competition


September 4, 2019

In today’s health conscious community, kombucha is all the rage. Its appeal comes from its accessibility and alleged health benefits, which range from introducing probiotics to killing deleterious bacteria in the human body. 

But as is the case for many things in science, there is more to kombucha than meets the eye — literally. The microscopic microbes inhabiting this fermented concoction could offer insight into how microbial communities interact, more specifically on how symbiotic relationships form within complex microbial models.

For Athena Aktipis, an assistant professor in the Department of Psychology and associate faculty in the Biodesign Center for Biocomputing, Security and Society at Arizona State University, being a fan of kombucha herself led to her delving deeper.

“Honestly, I started working on kombucha because I really liked the taste of it," she said. "I started brewing it in my kitchen for my own consumption. After brewing it for a couple of months, I would come home from work and just stare at it, asking, ‘How do you work?’ Being a scientist, I got on Google Scholar to learn more, but I didn’t find much.”

In response to this, Aktipis teamed up with other researchers to take all the pieces of the puzzle she had found in preexisting literature and put them together see the bigger picture on how kombucha operates and how the different species of microbes interact and cooperate within.

Alexander May, a prior researcher in Aktipis’s lab, led the efforts to expand on this knowledge in a review paper published in PeerJ, The Journal of Life and Environmental Sciences. Arvind Varsani, an associate professor in the Biodesign Center for Fundamental and Applied Microbiomics and School of Life Sciences and associate faculty in the Biodesign Center for Mechanisms of Evolution, and Carlo Maley, faculty in the School of Life Sciences and an associate professor in the Biodesign Center for Biocomputing, Security and Society, served as collaborators on the review paper.

The paper deconstructed each component of the microbial system, offering insight into how the microbes interact and what resources they utilize as a by-product of the fermentative processes used for making kombucha.

“We think kombucha is important as a model system because it’s an easy-to-grow microbial community that can potentially answer interesting questions about cooperation between different species,” May said. “Microbes, including the bacteria and yeast in kombucha, actually have a lot of complex social behaviors that scientists are only really starting to learn about. We think that by understanding what’s going on at the small scale, we can get clues as to what happens at the larger scale and see if the same patterns even hold true in human societies. People have been eating fermented foods like kombucha for centuries, but it’s only recently that scientists have started digging into the systems themselves to understand how and why they can benefit humans.”

Kombucha is made by first introducing sucrose to black or green tea, followed by the addition of kombucha liquid from a previous batch. A biofilm, also from a previous batch of kombucha, is then placed on top of the liquid, and the concoction is allowed to ferment for 10 to 14 days.

Although this may seem nothing more than a straightforward recipe for making a tasty refreshment, these fermentative steps actually sustain a wide variety of microbes, illustrating various ecological concepts we usually only see in real time with nonmicroscopic organisms.

"We are trying to develop kombucha as a system that could allow us to create new antimicrobial products."

— Athena Aktipis, assistant professor in the Department of Psychology and associate faculty in the Biodesign Center for Biocomputing, Security and Society 

For example, the yeast found in the kombucha liquid produces invertase, an enzyme that bacteria and yeast use to metabolize sugars, as a public good. Similarly, bacteria produce a biofilm at the top of the batch that protects microbes from outside invaders, provides oxygen and offers space for the storage of resources. Ethanol and acid, the by-products of fermentation, also keep invaders at bay.

However, there are many systems that have various microbial species at play, so why pick kombucha to illustrate these relationships?

“There is an ease of management that comes from it — because it is easy to make — but it also has a sort of complexity because it contains so many species, and in that way, it is similar to a microbial system you would see in nature,” Aktipis said. “It is at this really nice boundary between simplicity and complexity.” 

Kombucha has proven to be an efficient way to study interspecies interactions on the microbial scale, but it has much more to offer. From this study, Aktipis and collaborators are working on using kombucha as a model to develop interventions for bettering human health.

It has been recently brought into light how important the human microbiome is — the balance of microbes in our bodies, which we have co-evolved with since the dawn of humankind, is pivotal to human health. Throwing that balance off could have significant adverse effects, but treating humans with microbes could restore that balance.

“Right now, we are trying to develop kombucha as a system that could allow us to create new antimicrobial products, which are based on multiple species,” Aktipis said. “Whereas drugs are used to kill organisms, we want to ask, ‘How can we cultivate a diverse microbial community that can outcompete pathogens?’”

To do this, researchers are taking kombucha and introducing new invaders or removing some chemical or microbial component.

“We are trying to figure out which parts of cooperation in kombucha are most important,” Aktipis said. “This paper is the tip of the iceberg of a whole research program we are designing.”

These researchers are the first to look into kombucha as a model system — Aktipis says this is a good reminder to be aware of the world around and to never stop asking, "Why?"

“There is this tendency in science to only look at things that are already being studied. A lot of what we did with this kombucha project is coming back to the importance of observation, observing the natural world. I think that’s been a little bit lost, and it’s also much more fun to be aware of your world and to try to understand it.”
