Inaugural Week of Women in STEM

By: Sophia O’Brien

WSU’s inaugural Week of Women in STEM will be held April 2-5. It is a week to celebrate, acknowledge, and inspire women in the fields of science, technology, engineering, and mathematics. Women remain underrepresented in all fields of STEM, and are continually paid less than their male counterparts. Women can be credited for many accomplishments in science, but have historically been shadowed by male peers. While there are pioneers for women in the STEM fields like Jane Goodall, Rachel Carson, Mary Leakey, and Rosalind Franklin, young girls are still in dire need of role models in their everyday lives. The week is designed to help Washington State University women in STEM gain the confidence they need to excel in their futures.

On Monday, a screening of the acclaimed movie Hidden Figures will take place, it is the story of a team of female African-American mathematicians who served a vital role in NASA during the early years of the U.S. space program. CUB Auditorium at 8 p.m.

Events continue on Tuesday with a keynote address by Cougar Alumnae, Starbucks Executive V.P. and Chief Technology Officer, Gerri Martin- Flickinger.

A dinner on Wednesday night will include a networking session and panel discussion with STEM professionals. Dr. Noel Schulz, WSU First Lady and professor in the School of Electrical Engineering and Computer Science, will moderate the discussion. This is a private event that required previous registration and invite.

Thursday includes workshops by AAUW on salary negotiations. It will compromise of two workshops, one for those just beginning in their careers, and another on how to advocate for a raise or promotion. AAUW’s research on the gender pay gap shows that, one year out of college, women are already paid significantly less than their male counterparts.

The week wraps up with showings of WSU Performing Arts production of the play Silent Sky. Based on the true story of astronomer Henrietta Leavitt, the play explores a woman’s place in society during a time of immense scientific discoveries, when women’s ideas were dismissed—until men claimed credit for them.

Animal Cognition, Communication Expert Pepperberg to Deliver Jonas Lecture in Biology at WSU

Dr. Irene Pepperberg will present the 2018 Robert Jonas Lecture in Biological Sciences, “Cognitive and Communicative Abilities of Grey Parrots,” on Tuesday, March 27, at 6:00 p.m. in Todd Hall, 230. Pepperberg is a lecturer and research associate at Harvard University and well known for her comparative studies into the cognitive fundamentals of language and communication. She was one of the first to work on language learning in animals other than the human species. She is also active in wildlife conservation, especially related to parrots.

The 2018 Robert Jonas Lecture is sponsored by the WSU Zoology Club, School of Biological Sciences, and College of Arts & Sciences. The lectureship was established in memory of professor “Bob” Jonas, who taught biology and wildlife management at WSU for 25 years, and brings to campus prominent speakers on important conservation and environmental topics.

The Dirt on Undergraduate Research

By: Sophia O’Brien

Senior Claire Popke, doesn’t mind getting her hands dirty, especially if there are earthworms involved.

A few semesters ago, Popke decided she wanted to get involved in research as an undergraduate at WSU. Now she works closely with University of Idaho professor, Dr. Jodi Johnson-Maynard, analyzing soil samples’ isotopic C:N values in hopes of finding a relationship between earthworms and soil quality. This tells them how healthy the soil is by comparing the amount of carbon to the amount of nitrogen. They are looking into how the soil microbiology is affected by invasive and noninvasive earthworm species. Studying earthworms becomes challenging because, according to Popke, most earthworms are invasive species from Europe.

Because invasive species typically carry the connotation of being bad for a native area, Dr. Johnson-Maynard wanted to look into that relationship with earthworms. Invasive earthworms can damage the organic earth matter that sits on the forest floor. This could cause a transformation between of the relationships between plants and animals and the soil. Dr. Johnson-Maynard, her team of graduate students, and Popke are researching how these invasive earthworms could be affecting the Palouse environment.

According to Popke’s preliminary findings, there might not be a huge difference between native and invasive earthworms.

“Earthworms just seem to help the soil, whether they’re invasive or not,” she said. “This is different from most invasive species which are shown to be harmful.”

Popke grew up outside of Seattle in Edmonds, WA and has always been fascinated by earthworms. When she decided she wanted to get involved in undergraduate research, she looked to one of her favorite professors, Dr. Dave Evans. After class one day she asked if she could work in his lab, and soon began work with one of his graduate students. Popke began with helping the graduate student analyze her soil samples until Dr. Evans asked how she felt about earthworms; once he learned of her unique love for earthworms, he put her in contact with Dr. Johnson-Maynard at U of I.

Popke graduates this May from WSU and will head to Thailand the following month for a veterinary service. She plans on having that be a deciding factor in whether to pursue veterinary school or not. Popke feels she made find the conservation part of the project more exciting than the veterinary studies.

Undergraduate research has been a staple in Popke’s experience here. Not only did she feel more prepared for her microbiology classes because of it, but she feels more prepared for graduation in general.

SBS Students Become SBS Teachers

By: Sophia O’Brien

“A carnivore is a bat because they eat blood!” one MacDonald Elementary School student exclaimed.

Last November, my Biology 321 class presented developmental biology to elementary school students during Adventure Club, an after school program for elementary school students, mainly catering toward kindergarteners through third-graders. Though that first-grade student didn’t quite accurately guess what a carnivore was, he was on the right track for such a young kid.

When we walked into the elementary cafeteria where we’d be hosting the event, we were met with screams of excitement from the 70 kids running around.

As college students in biology 321, also known as Principles of Animal Development, we don’t have much contact with young children and had forgotten what elementary school was like. What we did know was that young children have short attention spans and like to participate in activities. Dr. Erica Crespi had invited us to show off what we had been learning in class at Adventure Club, and so we tried to come up with examples of the coolest stuff we could. We set up stations: one with skulls to look at teeth, one with bird specimens to look at feeding, a coloring sheet with information about morphology on it, and an interactive activity to learn about cells.

As we set up the different specimens we brought, the students clamored around excited about what we had to show. The beginning of every presentation began, “please don’t touch” and “you’ll get to touch it in a little”. The students were eager to begin learning.

The students loved the hands-on nature of all of our activities. My group taught students the correlation between teeth and eating habits, and how teeth develop throughout animals lives. We used baby and adult skulls from a dog, deer, and bear. All of the kids wanted to have their hand “bitten” by the bear skull. Using teeth to show development worked well with young kids because many of them are in the process of losing their own baby teeth. When one second grader was asked what he thought the bear skull was, he was convinced that it was a vampire. It took a lot of explanation for him to understand that the large “vampire” teeth he was seeing were actually canines.

Within our class, other groups did similar outreach projects with groups like Palouse Science Discovery Center, Bishop Center, Friends of Clearwater, and other Palouse organizations. Working with a community partner is an important process in science. It taught us to tailor what we were learning to different audiences with varying levels of scientific knowledge.

Dr. Crespi believes that “It is critical that our majors students learn how to communicate science to any audience that is interested through a variety of means—whether it be written, oral, visual, or in the case of children, with their hands–and this was a way to give them practice in doing just that. This skill is something all students can use no matter which profession or career they go into.”

SBS’s Conner Museum of Natural History Contains Wonders

By: Sophia O’Brien

In charge of over 61,000 specimens, Dr. Kelly Cassidy is the behind-the-scenes wizard of WSU’s Conner Museum.

Asked what it’s like being the curator for the Conner Museum, her response was simple: “I have the best job in the world. I learn something new every day.”

The museum houses the largest public exhibit of mounted birds and mammals in the Pacific Northwest. 700 mounted birds and mammals are on display.

But there are often surprises – it’s not just local fauna on display. For example, the museum houses one of the largest collections of birds from Mariana Islands; the museum was able to get these birds from the other side of the world because a former graduate student worked for the US Fish and Wildlife Service. The museum also has one of the largest collections of elephant teeth from Uganda because a former WSU professor, Dr. Irvin O. Buss, studied African elephants in the late 1950s and sent teeth back to Pullman just for the collections.

Cassidy has been helming the museum for a while now. When she began her work as curator 13 years ago, none of the collections were on computer file. If someone wanted to look at the rodent records from Spokane County, someone would have to go through and look at all the labels on thousands of rodent skins and skulls and write down that information. Cassidy decided that having computerized records were essential. She began with the massive bird collection, and over the course of several years, entered them in. Eventually, she received an NSF grant to hire students to help finish the computerization. Having specimens within a computer base allows researchers to find the specimens, and put in requests for them.Cassidy began her work in Pullman following a postdoc in Seattle. She came back for a temporary job, only to then have the curator job become available. Wanting to stay in Pullman, she instantly jumped on the opportunity, and has never looked back.

Cassidy received her bachelor’s degree in physics and math from the University of Texas. She began graduate school with the goal of ending it with a degree in physics, but kept finding herself drawn to biology journals in the library. Cassidy decided to earn a master’s degree in biology from the University of North Texas, having never taken a biology course before. There, her projects involved water toxicology and satellite imagery. She came to WSU for a PhD in botany under Dr. Dick Mack, focusing on invasive plants. During her post-doc at the University of Washington, she was the Washington state project leader for the Gap Analysis Project (GAP). In her time as GAP leader, she used satellite imagery to map vegetation across the state, modeled the distribution of terrestrial vertebrates and overlaid the vertebrate maps on land ownership to identify “gaps” in the protection of vertebrates in the state.

Recently, the Conner Museum was lucky enough to receive a donation of five big cat rugs. The collection includes an adult male lion, adult tiger, juvenile tiger, and two leopards. A WSU economics professor, Robert Wallace, shot them in the 1950s; he later regretted killing them and stored them away in a chest. His daughter came across these pelts when cleaning out his house. They will be used for presentations and teaching demonstrations.

The Conner Museum is located in the south end floor of Abelson Hall. It is open seven days a week from 8 a.m. to 5 p.m. (closed major Holidays and during University Closures).

Eric Navarro Is Named a Winner at the SACNAS Conference

By: Sophia O’Brien

A presentation by SBS undergraduate junior, Eric Navarro, was one of the 117 winners of 1000+ student research presentations at the Society for Advancement of Chicanos/Hispanics and Native Americans in Science (SACNAS) National Diversity in STEM Conference on October 19-21.

SACNAS, which hosted the event, is the leading multicultural and multidisciplinary STEM diversity organization in the country. The conference included over 4000 attendees and 1000 student research presentations in multidisciplinary fields.

When Navarro walked into the convention center, he said he felt awe at the number of people from under-represented communities pursuing STEM degrees.

“There wasn’t a lack of cultural experience either,” he said. “There were many different presentations throughout the conference showcasing the beauty of a range of cultures.”

Navarro was the only winner in the animal science/zoology field with his presentation, “Retention of learning through life stages in Xenopus laevis”. Xenopus laevis is commonly known as an African clawed frog. His research hopes to find the effects of early life (pre-metamorphosis) stress have on later life (post-metamorphosis) learning. This could translate into understanding the effects of stress on human babies in the womb and learning in later human life. Metamorphosis is typically viewed as a fresh start for an animal, like hatching, but if early life stress has negative effects on cognitive function after metamorphosis, then it would confirm newer hypotheses that some effects can be retained even through metamorphosis.

Navarro grew up in the small town of Quincy, WA where, due to lack of activities, he spent a lot of his time watching the animals around him react to stimuli. Navarro has always loved animals and science, but his curiosity is what has driven him into the world of animal behavior. He is a member of the Gamma Iota Omicron, Fraternity Inc., and one of the founding members of WSU SACNAS chapter.

His parents originated from Jalisco, Mexico before moving to the United States. Being of Mexican heritage, he has found it rare to find a person of color in a high-ranking position. In STEM, he said he has often felt uneasy about the lack of people of color pursuing degrees, and the lack of faculty members who have looked like him. Navarro believes role models can be found anywhere, but it’s harder to make a connection when you don’t have someone who understands how it feels to be a Mexican-American, first-generation college student. His goal is to become an academic in STEM, so that he can show someone like him, who is on the edge of continuing, that they can be successful in the field.

One of his goals for this year was to present at a big conference, and with the help of his mentor, Dr. Erica Crespi, SACNAS was his largest conference yet. No matter how smart one may be, he said, if findings aren’t communicated to other scientists and people outside the scientific community, the true potential of one’s research won’t be fulfilled.

In the future, Navarro plans to get a Ph.D. in Animal Behavior. His interests lie in how the animal’s environment, if bad at any point in time, can have lasting impacts on the animal’s behavior. Eventually he hopes to enter academia or work as an animal behaviorist at a zoo.
