Infection Interruption: Identifying Compounds that Disrupt HIV

Know the enemy

Comparing microbial extracts with Dr. Sandra Loesgen.

The Human Immunodeficiency Virus, or HIV, is the virus that leads to Acquired Immunodeficiency Syndrome (AIDS). Most of our listeners have likely heard about HIV/AIDS because it has been reported in the news since the 1980s, but our listeners might not be familiar with the virus’s biology and treatments that target the virus.

  • HIV follows an infection cycle with these main stages:
    • Attachment – the virus binds to a host cell
    • Fusion – the viral wall fuses with the membrane of the host cell and genetic material from the virus enters the host cell
    • Reverse transcription – RNA from the virus is converted into DNA via viral enzymes
    • Integration – viral DNA joins the genome of the host cell
    • Reproduction – the viral DNA hijacks the host cell activity to produce more viruses and the cycle continues
  • Drug treatments target different stages in the HIV infection cycle to slow down infection
  • However, HIV has adapted to allow mistakes to occur during the reverse transcription stage such that spontaneous mutations change the virus within the host individual, and the virus becomes tolerant to drug treatments over time.

Faulty Machinery

Due to the highly mutable nature of HIV, a constant supply of new drug treatments are necessary to fend off resistance and treat infection. Our guest this week on Inspiration Dissemination, Ross Overacker a PhD candidate in Organic Chemistry, is screening a library of natural and synthetic compounds for their antiviral activity and effectiveness at disrupting HIV. Ross works in a Natural Products Lab under the direction of Dr. Sandra Loesgen. There, Ross and his lab mates (some of whom were on the show recently [1] [2]) test libraries of compounds they have extracted from fungi and bacteria for a range of therapeutic applications. Ross is currently completing his analysis of a synthetic compound that shows promise for interrupting the HIV infection cycle.

Havin’ a blast

Chemistry Club at Washington State University (WSU) initially turned Ross onto chemistry. The club participated in education outreach by presenting chemistry demonstrations at local high schools and club events. Ross and other students would demonstrate exciting chemistry demos such as filling hydrogen balloons with salt compounds resulting in colorful explosions piquing the interest of students and community members alike. Ross originally made a name in

Collecting Winter Chanterelles in the Pacific Northwest.

WSU’s chemistry club, eventually becoming the president, by showing off a “flaming snowball” and tossing it from hand to hand—don’t worry he will explain this on air. For Ross, chemistry is a complicated puzzle that once you work out, all of the pieces fall into place. After a few undergraduate research projects, Ross decided that he wanted to continue research by pursing a PhD in Organic Chemistry at Oregon State University.

Learning without a brain

Instructions for how to win a soccer game:

Score more goals than your opponent.

Sounds simple, but these instructions don’t begin to explain the complexity of soccer and are useless without knowledge of the rules of soccer or how a “goal” is “scored.” Cataloging the numerous variables and situations to win at soccer is impossible and even having all that information will not guarantee a win. Soccer takes teamwork and practice.

Researchers in robotics are trying to figure out how to make a robot learn behaviors in games such as soccer, which require collaborative and/or competitive behaviors.

How then would you teach a group of robots to play soccer? Robots don’t have “bodies,” and instructions based on human body movement are irrelevant. Robots can’t watch a game and later try some fancy footwork. Robots can’t understand English unless they are designed to. How would the robots communicate with each other on the field? If a robot team did win a soccer game, how would they know?

Multiple robot systems are already a reality in automated warehouses.

Although this is merely an illustrative example, these are the types of challenges encountered by folks working to design robots to accomplish specific tasks. The main tool for teaching a robot to do anything is machine learning. With machine learning, a roboticist can give a robot limited instructions for a task, the robot can attempt a task many times, and the roboticist can reward the robot when the task is performed successfully. This allows the robot to learn how to successfully accomplish the task and use that experience to further improve. In our soccer example, the robot team is rewarded when they score a goal, and they can get better at scoring goals and winning games.

Programming machines to automatically learn collaborative skills is very hard because the outcome depends on not only what one robot did, but what all other robots did; thus it is hard to learn who contributed the most and in what way.

Our guest this week, Yathartha Tuladhar, a PhD student studying Robotics in the College of Engineering, is focused on improving multi-robot coordination. He is investigating both how to effectively reward robots and how robot-to-robot communication can increase success. Fun fact: robots don’t use human language communication. Roboticists define a limited vocabulary of numbers or letters that can become words and allow the robots to learn their own language. Not even the roboticist will be able to decode the communication!

 

Human-Robot collaborative teams will play a crucial role in the future of search and rescue.

Yathartha is from Nepal and became interested in electrical engineering as a career that would aid infrastructure development in his country. After getting a scholarship to study electrical engineering in the US at University of Texas Arlington, he learned that electrical engineering is more than developing networks and helping buildings run on electricity. He found electrical engineering is about discovery, creation, trial, and error. Ultimately, it was an experience volunteering in a robotics lab as an undergraduate that led him to where he is today.

Crabby and Stressed Out: Ocean Acidification and the Dungeness Crab

One of the many consequences associated with climate change is ocean acidification. This process occurs when high atmospheric carbon dioxide dissolves into the ocean lowering ocean pH. Concern about ocean acidification has increased recently with the majority of scientific publications about ocean acidification being released in the last 5 years. Despite this uptick in attention, much is still unknown about the effects of ocean acidification on marine organisms.

Close-up of a Dungeness crab megalopae

Our guest this week, Hannah Gossner, a second year Master’s student in the Marine Resource Management Program, is investigating the physiological effects of ocean acidification on Dungeness crab (Metacarcinus magister) with the help of advisor Francis Chan. Most folks in Oregon recognize the Dungeness crab as a critter than ends up on their plate. Dungeness crab harvest is a multimillion dollar industry because of its culinary use, but Dungeness crab also play an important role in the ocean ecosystem. Due to their prevalence and life cycle, they are important both as scavengers and as a food source to other animals.

To study the effect of ocean acidification on Dungeness crab, Hannah simulates a variety of ocean conditions in sealed chamber where she can control oxygen and carbon dioxide levels. Then by measuring the respiration of an individual crab she can better understand the organism’s stress response to a range of oxygen and carbon dioxide ratios. Hannah hopes that her work will provide a template for measuring the tolerance of other animals to changes in ocean chemistry. She is also interested in the interplay between science, management, and policy, and plans to share her results with local managers and decision makers.

Growing up in Connecticut, Hannah spent a lot of time on the water in her dad’s boat, and developed an interest in marine science. Hannah majored in Marine Science at Boston University where she participated in a research project which used stable isotope analysis to monitor changes in food webs involving ctenophores and forage fish. Hannah also did a SEA Semester (not to be confused with a Semester at Sea) where she worked on a boat and studied sustainability in Polynesian island cultures and ecosystems.  Hannah knew early on that she wanted to go to graduate school, and after a brief adventure monitoring coral reefs off the coast of Africa, she secured her current position at Oregon State.

A Space for Me

Minerva presenting at the Radical Imaginations Conference on the panel ” Feminist Radical Imaginations: Marches and Revolutions” with Andrea Haverkamp, Carolina Melchor, Maria Lenzi Miori, Minerva Zayas, and Nasim Basiri

Everyone handles their personal growth differently, and for many finding an identity category can lead to feelings of comfort and an opportunity to find community. However, for folks who identify with more than one category or find identity in LGBTQ+ categories may find difficulty navigating their identity in spaces that have been shaped by the heteronormative majority. Moreover, for people of color, retaining identity in their culture might add another layer of complexity to navigating the path to their goals. Our guest this week, Minerva Zayas a Master’s student in Women, Gender, and Sexuality Studies, is interested in how folks who identify as LatinX and LGBTQ+ navigate the intersection of these identities, especially in university spaces. In particular, Minerva is asking how LatinX, LGBTQ+ individuals engage in a system that has historically catered to white heteronormative college students. Minerva, speaking from personal experience, expects that University life offers little tailored support systems for folks of color who identify as ‘other,’ but that a university campus might offer opportunities to build a support systems that other institutions might lack: the opportunity to participate in a campus cultural/lifestyle community and engage in activism.

Minerva presenting at Corvallis Poetics Open Mic Night on the poem, “My worst NightMare” at Interzone Inc.

Minerva participating in a creative photo session in downtown Corvallis, OR.

For her Master’s, Minerva will conduct interviews with LatinX, LGBTQ+ students and ask questions than run the gamut of identity in sexuality, culture, community, and activism. She hopes to highlight their experiences and examine themes that arise. In addition to her research, Minerva, a poet herself, plans to extend her project in a creative way, ideally through a podcast. After completing her Master’s, Minerva hopes to complete a PhD and has considered becoming a counselor for Spanish-speaking folks. This aim coincides with her mission to bring voice to folks who share identity with her in LatinX culture. Minerva ultimately wants institutions, academia and beyond, to be more inclusive and cognizant of minority identities, but she realizes that change comes from within. By pursuing her aspirations for a PhD and engaging in academia, she hopes that others who share her identity will be drawn to academia so that a system that has been shaped by the majority identity can grow to support all.

Tune in to KBVR Corvallis 88.7 FM this Sunday May, 20 at 7 pm to hear more about Minerva’s research and personal journey to graduate school. Listeners, local and otherwise, can stream the live interview at kbvr.com/listen or find the podcast of Minerva’s episode next week on Apple Podcasts.

 

Comunicación Científica con Franco

This week on Inspiration Dissemination we will be featuring a previous guest: Francisco Guerrero, a PhD student in the Department of Forest Engineering, Resources, and Management. Francisco’s first interview aired on October 18, 2015, and we called him back for a follow-up because he has been selected for the American Association for the Advancement of Science (AAAS) Mass Media Science and Engineering Fellowship. As a fellow, Franco will be writing feature stories about climate change and health for CNN en Español. Part of the fellowship will involve helping with film production, as well. FUN FACT last time Franco was on the show, he told us that he always wanted to be a movie producer. Franco will take this amazing opportunity during the final push for his PhD research to enhance his science communication skills and gain experience in production and video broadcasting.

This special interview will begin at 6:30 pm on May 6, 2018. We will be asking Franco about the application process, his responsibilities as a fellow, and his goals for the fellowship. After our interview with Franco, we will rebroadcast his first interview on Inspiration Dissemination at 7 pm.

Tune in to KBVR Corvallis 88.7 FM at 6:30 pm to hear about the AAAS Fellowship and learn about Franco’s research in the College of Forestry. Not a local listener? No sweat! Stream the show live on line or hear the podcast next week.

Aquatic Invertebrates: Why You Should Give a Dam

Rivers are ecosystems that attract and maintain a diversity of organisms. Fish, birds, mammals, plants, and invertebrates live in and around rivers. Have you considered what services these groups of organisms provide to the river ecosystem? For example, river invertebrates provide numerous ecosystem services:

Dragonfly larvae caught in in the waters of a small stream flowing into the Grand Canyon.

  • Insects and mussels improve water quality by fixing nutrients, such as those from agricultural runoff.
  • River invertebrates are food resources for fish, bats, birds, and other terrestrial organisms.
  • Grazing insects can control and/or stimulate algal growth.
  • Mussels can help to stabilize the bed of the river.

High school students are the best helpers for sampling aquatic insects!

And the list continues. These invertebrates have adapted to the native conditions of their river ecosystem, and major disturbances, such as a change in the flow of a river from a dam, can change the community of organisms downstream. If dams decrease the diversity of invertebrates downstream, then they may also decrease the diversity of ecosystem services offered by the invertebrate community.

Our guest this week, Erin Abernethy PhD candidate from the department of Integrative Biology, is investigating the community structure (or the number of species and the number of individuals of each species) of freshwater aquatic invertebrates downstream of dams. Specifically, Erin wants to know if invertebrate communities near dams of the Colorado River are different than those downstream, and which factors of dams of the Southwest US affect invertebrate communities.

Getting to field sites in the Grand Canyon is easiest by raft! It’s a pretty float, too!

Erin’s dissertation also has a component of population genetics, which examines the connectivity of populations of mayflies,populations of caddisflies, and populations of water striders. The outcomes of Erin’s research could inform policy around dam operation and the maintenance of aquatic invertebrate communities near dams.

“One must dress for sampling success in the Grand Canyon!” said this week’s guest, Erin Abernethy, who is pictured here.

Growing up, Erin participated in many outdoor activities with her parents, who are biologists. She became interested in how dams effect ecology, specifically fresh water mussels, doing undergraduate research at Appalachian State University. After undergrad, Erin completed a Master’s in Ecology from University of Georgia. She was investigating the foraging behavior of animals in Hawaii. This involved depositing animal carcasses and monitoring foraging visitors. Check out Erin’s blog for photos of these animals foraging at night! Erin decided to keep going in academia after being awarded a Graduate Research Fellowship, which landed her a position in David Lytle’s lab here at Oregon State. After she completes her PhD, Erin is interested in working for an agency or a nonprofit as an expert in freshwater ecology and the maintenance of biodiversity in freshwater ecosystems.

How many robots does it take to screw in a light bulb?

As technology continues to improve over the coming years, we are beginning to see increased integration of robotics into our daily lives. Imagine if these robots were capable of receiving general instructions regarding a task, and they were able to learn, work, and communicate as a team to complete that task with no additional guidance. Our guest this week on Inspiration Dissemination, Connor Yates a Robotics PhD student in the College of Engineering, studies artificial intelligence and machine learning and wants to make the above hypothetical scenario a reality. Connor and other members of the Autonomous Agents and Distributed Intelligence Laboratory are keenly interested in distributed reinforcement learning, optimization, and control in large complex robotics systems. Applications of this include multi-robot coordination, mobile robot navigation, transportation systems, and intelligent energy management.

Connor Yates.

A long time Beaver and native Oregonian, Connor grew up on the eastern side of the state. His father was a botanist, which naturally translated to a lot of time spent in the woods during his childhood. This, however, did not deter his aspirations of becoming a mechanical engineer building rockets for NASA. Fast forward to his first term of undergraduate here at Oregon State University—while taking his first mechanical engineering course, he realized rocket science wasn’t the academic field he wanted to pursue. After taking numerous different courses, one piqued his interest, computer science. He then went on to flourish in the computer science program eventually meeting his current Ph.D. advisor, Dr. Kagan Tumer. Connor worked with Dr. Tumer for two of his undergraduate years, and completed his undergraduate honors thesis investigating the improvement to gauge the intent of multiple robots working together in one system.

Connor taking in a view at Glacier National Park 2017.

Currently, Connor is working on improving the ability for machines to learn by implementing a reward system; think of a “good robot” and “bad robot” system. Using computer simulations, a robot can be assigned a general task. Robots usually begin learning a task with many failed attempts, but through the reward system, good behaviors can be enforced and behaviors that do not relate to the assigned task can be discouraged. Over thousands of trials, the robot eventually learns what to do and completes the task. Simple, right? However, this becomes incredibly more complex when a team of robots are assigned to learn a task. Connor focuses on rewarding not just successful completion an assigned task, but also progress toward completing the task. For example, say you have a table that requires six robots to move. When two robots attempt the task and fail, rather than just view it as a failed task, robots are capable of learning that two robots are not enough and recruit more robots until successful completion of the task. This is seen as a step wise progression toward success rather than an all or nothing type situation. It is Connor’s hope that one day in the future a robot team could not only complete a task but also report reasons why a decision was made to complete an assigned task.

In Connor’s free time he enjoys getting involved in the many PAC courses that are offered here at Oregon State University, getting outside, and trying to teach his household robot how to bring him a beer from the fridge.

GROWing Healthy Kids and Communities

Physical activity has many benefits for health and wellness. Physical activity can help us control our weight, reduce our risk of diseases including many cancers and type 2 diabetes, help to strengthen our bones and muscles, and improve our mental health. Yet despite the benefits, many don’t get the recommended amount of physical activity. Our guest this week, Evan Hilberg from the College of Public Health and Human Sciences and the Department of Kinesiology, is investigating factors that influence physical activity of children in rural communities. Research focused on physical activity in children disproportionally centers around children in urban communities. Children in rural communities may have different limitations to physical activity. For example, rural children are more likely to take the bus to school instead of walking and commutes may take up to two hours each way. This leaves little time for physical activity outside of school hours. With his advisors, John Schuna and Kathy Gunter, Evan is analyzing data collected as part of the Generating Rural Options for Weight- Healthy Kids and Communities (GROW HKC) to better understand when children are active during the school day and factors that might limit their physical activity.

Recess and Wellness

Evan taking blood samples for cholesterol and glucose testing at a Community Wellness Fair.

One area of interest for Evan and the GROW HKC project are the variables that may predict changes in Body Mass Index (BMI) over a three-year period. Through this longitudinal study that involves over 1000 rural Oregon elementary school children, Evan will identify correlates of BMI change such as physical activity levels, age, sex, teacher, and school. Additionally, Evan is analyzing data that will hopefully provide more insight into specifically what times during the school day children are active. By obtaining a classroom schedule from teachers and measuring activity with accelerometers and pedometers, Evan can infer if children are physically active during recess, P.E., classroom activity breaks, or other times during the school day. Finally, Evan’s data will examine the reliability of different objective measures of physical activity, such as pedometers and accelerometers. The ability to compare outputs from different devices is limited by changes in device hardware and software, as well as the ways in which data is processed within those devices. The examination of these devices may inform procedure for future physical activity research for children and adults to help comparability across different devices and different studies.

A School of Thought

A clear understanding of the factors effecting physical activity in rural school children will aid in structuring the school day to maximize each child’s opportunity to be physically active. Data generated through GROW HKC my reveal patterns that younger children are more active during unstructured play during recess, whereas older children prefer sports-focused activity in P.E.. This type of research could inform recommendations for state-mandated physical activity at schools such that school day structure and physical activity opportunities are tailored to the diverse needs of kids in rural communities.

Full Circle

Evan grew up as an active kid and selected a college where he could play baseball. He landed at Linfield College in McMinnville, Oregon where his interest in Exercise Science grew through volunteering in community health outreach and research with his advisor, Janet Peterson. Evan learned that his education went beyond the classroom through his interactions with the community. Evan decided to pursue graduate school and earned a Master’s degree in Exercise Physiology from Eastern Washington University. During his Master’s, Evan gained more experience with community and public health research as an AmeriCorps employee with Let’s Move, Cheney”, a local coalition inspired by Michelle Obama’s national campaign. Thereafter, Evan volunteered with the GROW HKC project, and applied to graduate school at Oregon State. Since beginning his doctoral studies with a concentration in physical activity and public health, Evan has completed a Master’s in Public Health in Biostatistics and maintains a full-time job as a Medical Policy Research Analyst with Cambia Health Solutions.

Clean Meat, Clean Conscience

Some may say, “there is nothing like a juicy hamburger,” and here is the USA we are fortunate to have access to affordable meat. While the cost of your next hamburger may not weigh too heavily on your pocket, the quantity resources required to produce one pound of beef may surprise you. One pound of meat is fed by nearly 7 pounds of grain, 53 gallons of water, 70 square acres of land, and 1,000 BTU of energy(The Meat Revolution- Mark Post). Additionally, animal agriculture produces 5 times the amount of greenhouse gasses than other food sources (Smithsonian Mag). Finally, 56 billion land animals are killed every year solely for food. The impacts on marine animals are high as well but difficult to estimate. More information about the impacts of animal agriculture. But what can be done? Is there a better way to grow meat that uses less resources and reduces animal suffering?

From the petri dish to the plate

Bjørn on the Oregon State University campus

Yes, our guest this week, Bjørn Kristensen from the School of History, Philosophy, and Religion, studies the ethics behind cultured meat or clean meat. Similar scientific advances in muscle tissue culture that have led to lab grown human organs are now being harnessed to grow animal muscle for human consumption. Clean meat is made from cells that can be obtained with no harm to the animal donor. One company, Hampton Creek Foods, has cultured chicken muscle with cells from a chicken feather. Hampton Creek Foods and Finless Foods are focused on producing clean meat with zero animal suffering. Clean meat is literally clean because it is grow under 100% sterile conditions. This means no natural parasites or other infections, and no need for antibiotics nor artificial growth hormones. While Bjorn maintains that the best option for the both purposes of sustainability and reduction in animal suffering is eliminating animal products from one’s diet, within the next year or two, companies such as Hampton Creek and Finless Foods will be introducing clean meat which is structurally identical to meat coming from mainstream animal agriculture. This means that even those who choose not to stop eating meat will have options that do not require an animal to be killed for their food.

The best part: by some estimates a few animal cells can be used to grow 10,000 kg of meat (The Meat Revolution- Mark Post). Practically speaking, clean meat could reduce the number of cows in animal agriculture from half a billion to thirty thousand. This reduction animal agriculture would free up land and resources for other food sources such as vegetable crops, lessen the amount of greenhouse gasses being emitted by animal agriculture, and it would lower animal suffering.

When practicality meets ethics

Bjørn with a resident of Green Acres Farm Sanctuary in Silverton, Oregon where he volunteers.

Animal agriculture is an ethical issue. The intersection occurs when humans act as mediator and place the needs of one species over the needs of another. Bjorn studies this ethical conundrum. In the case of animal agriculture,we have placed our desire for meat over the needs of the individual animals within the current food system. For these animals, their entire life is planned for their death, process, and consumption, and this planned “life” comes with emotional consequences for the animals. Check out this video about chickens, considered one of the most abused animals. Clean meat could alleviate the need for so much animal suffering to feed humans and other non-human animals.

Not convinced?

Bjørn with his dog, Thor.

Consider this: humans are not the only animals on the planet that consume meat from animal agriculture. While humans can actually survive and thrive on a plant-based diet, other carnivorous animals must consume flesh to survive. Pets, zoo animals, and wildlife in rehabilitation also require animal proteins, and the animals that are harvested to produce pet food are at the bottom of the food chain. Removing small fish or small rodents from natural ecosystems means that animals in the wild have to get energy from other sources. For some wild animals, such as marine mammals, this is simply not possible. Few have considered that clean meat could become an alternative protein source for pets and other wildlife that have been removed from their natural habitat. Bjørn explored the ethics of “captive predation” or feeding captive animals with other animal protein sources in a recent paper that he presented at the International Conference on Cultured Meat in Maastricht, the Netherlands.

Because it’s who you are

Receiving the award for outstanding philosophical essay from his undergrad professor, Antony Aumann.

Bjørn’s “when I grow up” career choice was a veterinarian, and although not a vet now, his concern for animals has not dwindled. During college, Bjørn started out as a Human Services major at Finlandia University, but switched his focus after taking some philosophy and religious studies classes. Eventually, he transferred to Northern Michigan University and found a connection between concern for animals and philosophical study, particularly in animal ethics.  Bjørn began to consider graduate school after his professor in existentialism, Anthony Aumann, encouraged him to apply. Bjørn applied toOregon State University, and began to develope his thesis concerning inter-species justice with Robert Figueroa his major advisor.
