University scientists conduct, shed light on microbiome research to help impoverished children grow

Changing children’s digestive tract microbes key to reducing disease, improving health

Millions of children worldwide experience diarrheal infections that cause malnourishment and stunted physical and mental growth. This is a problem not only for the children, but also on a larger scale. A country’s children are its future workers, including its leaders and inventors. When one suffers, so does the other.

University Assistant Professor Steven Frese, with the College, is working to help. He recently published a  with scientists from around the world. The research shows that a specific probiotic strain, a live bacterium that lives in the body, helps severely malnourished Bangladeshi infants grow.

Frese also wrote an American Journal of Gastroenterology invited opinion with a colleague from the University’s School of Medicine, Dr. Mark Riddle. The pair’s paper summarizes existing research on the microbiome, malnutrition and stunting. It explains that at-risk children’s downward spiral of infection, gut dysfunction and malnourishment has far-felt effects. And, changing the children’s gut microbiome, the collection of bacteria, fungi and other microbes that live in the digestive tract, helps prevent this spiral that leads to malnourishment.

New University study utilizes supplemental feeding to attract cattle to infested pastures

Mike Wolterbeek

Scientists at the University have discovered that fire danger can be reduced through the application of targeted cattle grazing in the dormant growing season by attracting the cattle with feeding stations containing liquid protein feed supplements.

Cheatgrass, an invasive annual grass that has invaded Nevada rangelands, is responsible for much of the increasing wildfire danger in the Intermountain West. However, scientists at the University have discovered that fire danger can be reduced through the application of targeted cattle grazing in the dormant growing season by attracting the cattle with stations containing protein feed supplements.

"Our work establishes that protein feed supplements in the fall and early winter can attract cattle to locations dominated by cheatgrass, significantly reducing the standing fine-fuel biomass by more than 50%, while making room for native grasses to grow," Professor Barry Perryman said.

One of the greatest ecological threats to ecosystems of the Intermountain West has been and will continue to be invasive annual grasses. Strategic supplementation provides a valuable tool to target cattle grazing at specific locations within cheatgrass-invaded systems to reduce fine fuel buildup during the dormant season, according to the .

Authors of the journal article include Perryman, with the College’s Department of Agriculture, Veterinary & Rangeland Sciences and also part of the College’s Experiment Station unit, and Brad Schultz, professor in the College’s Extension unit.

Nevada volunteer honored in national awards for over three decades of service to 4-H youth

4-H volunteer Linda Zimmerman was named 4-H Western Region Outstanding Lifetime Volunteer

Prior to her recent award, Linda Zimmerman (left) was awarded the 2021 Nevada 4-H Volunteer of the Year by Sue Hoffman, executive director of the Nevada Agriculture Foundation.

Nevada’s Linda Zimmerman, a 4-H volunteer for Extension for over 34 years and a University alumna, is one of only four 4-H volunteers nationally to have recently been named a 4-H Outstanding Lifetime Volunteer. Zimmerman was named the 4-H Western Region Outstanding Lifetime Volunteer as part of the 4‑H Salute to Excellence Awards for her dedication and service to Extension’s Washoe County 4-H Horse Program and support of youth statewide.

Participating in the 4-H Youth Development Program as a youth herself, Zimmerman went from being a club member to being the parent of 4-H youth, and then a 4-H club leader and a 4-H Leaders’ Council member. Her positive impact on youth in her club has inspired many past participants to enroll their own children in the program, and to become 4-H leaders themselves.

Having earned her doctoral degree in social psychology from the University, she is interested in trying new strategies for engagement and retention, while supporting youth and their families in figuring out how best to participate in clubs and activities.

Environmental science student-researcher wins Regents’ award for notable accomplishments

Nicole Choma reflects on how experiences in undergraduate research, marching band and other scholarly activities have enhanced her college journey

Nicole Choma received the Sam Lieberman Regents’ Award for Student Scholarship at the 2022 "Honor the Best" ceremony.

As environmental science major in the College Nicole Choma wrapped up her third year at the University this May, she received the Sam Lieberman Regents’ Award for Student Scholarship. Choma, an Honors College student also majoring in biology, won the award due to her outstanding student achievements, including her impressive and ongoing undergraduate research projects and participation in the Wolf Pack Marching Band.

Choma was surprised when Mae Gustin, a professor in the College, reached out and wanted to nominate her for the award. The support Choma received from Gustin and other mentors in gave Choma many opportunities to develop valuable professional skills and feel more comfortable in a laboratory setting.

, director of the College’s Experiment Station unit’s Core Analytical Laboratory, mentored Choma in funding, creating, designing and presenting her own research. Choma’s research project is investigating the absorption and desorption of mercury from microplastics and the aquatic ecosystem.

She said, “Outside of the impacts of microplastics, we should know if there's anything being carried on [them], because that can change how we think about what's going into our bodies, what's going into our food, what's going into our plants.”
