Scientists uncover how fermented-food bacteria can guard against depression, anxiety
Last Updated on November 9, 2024 by Daily News Staff
Newswise — University of Virginia School of Medicine researchers have discovered how Lactobacillus, a bacterium found in fermented foods and yogurt, helps the body manage stress and may help prevent depression and anxiety. The findings open the door to new therapies to treat anxiety, depression and other mental-health conditions.
The new research from UVA’s Alban Gaultier, Ph.D., and collaborators is notable because it pinpoints the role of Lactobacillus, separating it out from all the other microorganisms that naturally live in and on our bodies. These organisms are collectively known as the microbiota, and scientists have increasingly sought to target them to battle disease and improve our health. UVA’s new research represents a major step forward in that effort, providing scientists an innovative new approach to understand the role of individual microbes that could facilitate the development of new treatments and cures for a wide variety of diseases, both mental and physical.
“Our discovery illuminates how gut-resident Lactobacillus influences mood disorders, by tuning the immune system,” said Gaultier, of UVA’s Department of Neuroscience, the Center for Brain Immunology and Glia (BIG Center) and the TransUniversity Microbiome Initiative. “Our research could pave the way towards discovering much-needed therapeutics for anxiety and depression.”
The Microbiota and Depression
Our guts are naturally home to countless bacteria, fungi, and viruses. There are more microorganisms living in and on us than there are cells in our bodies. That may sound disgusting, even alarming, but scientists have increasingly realized that these tiny organisms and their endless interactions are critical to our immune systems’ health, our mental health, and many other facets of our well-being. Disruptions of the microbiota, whether from illness, poor diet, or other causes, are known to contribute to many diseases and even help cancer spread. So, researchers have been hugely excited in recent years about the potential to battle diseases by targeting the microbiota.
Early attempts to manipulate the gut flora with beneficial bacteria, called probiotics, have produced mixed results. A big part of the problem has been the sheer complexity of the microbiome. It’s estimated that there are 39 trillion microorganisms inside each of us, so trying to understand what specific bacteria or fungi do – much less how they interact with all the other microorganisms and their host – can be like trying to count grains of sand on the beach.
Gaultier and his team took an innovative approach to hone in on Lactobacilli in specific. Prior research from Gaultier’s lab suggested that the bacteria could reverse depression in lab mice – a hugely promising finding. But the researchers needed to understand how.
“We were aware from our prior research that Lactobacillus was beneficial in improving mood disorders and was lost following psychological stress, but the underlying reasons remained unclear, primarily due to the technical challenges associated with studying the microbiome.”
Gaultier and his team decided to continue their depression research using a collection of bacteria, known as Altered Schaedler Flora, which includes two strains of Lactobacillus and six other bacterial strains. With this rarely used bacterial community, the team was able to create mice both with and without Lactobacillus,circumventing the need for antibiotics.
Sure enough, the Altered Schaedler Flora produced exciting results. Gaultier and his colleagues were able to explain exactly how Lactobacilli influence behavior, and how a lack of the bacteria can worsen depression and anxiety. Lactobacilli in the family Lactobaccillacea, they found, maintain the levels of an immune mediator called interferon gamma that regulates the body’s response to stress and helps stave off depression.
Armed with this information, researchers are poised to develop new ways to prevent and treat depression and other mental-health conditions in which Lactobacillus plays an important role. For example, patients struggling with (or at risk for) depression might one day take specially formulated probiotic supplements that will optimize their levels of helpful Lactobacillus.
“With these results in hand, we have new tools to optimize the development of probiotics, which should speed up discoveries for novel therapies,” said researcher Andrea R. Merchak, Ph.D. “Most importantly, we can now explore how maintaining a healthy level of Lactobacillus and/or interferon gamma could be investigated to prevent and treat anxiety and depression.”
Findings Published
The UVA scientists have published their findings in the journal Brain Behavior and Immunity. The research team consisted of Merchak, Samuel Wachamo, Lucille C. Brown, Alisha Thakur, Brett Moreau, Ryan M. Brown, Courtney Rivet-Noor, Tula Raghavan and Gaultier. The researchers have no financial interest in the work.
The work was supported by the National Institutes of Health, grants T32 NS115657, T32 GM008136, F31 AI174782, T32 GM007267 and T32 GM148379; the Owens Family Foundation; the Miller Family; the UVA TransUniversity Microbiome Initiative; and the UVA Presidential Fellowship in Neuroscience.
UVA’s TransUniversity Microbiome Initiative, or TUMI, serves as the central hub for the University’s cutting-edge microbiome research. The initiative aims to expand our understanding of the microbiome to better treat and prevent disease.

Millions of mobile gamers prize stress relief over winning
Mobile Gamers Prize Stress: In the school’s car pickup line, five minutes before it starts moving. In the doctor’s office waiting room for an appointment that you’ve been heavily anticipating. In bed, just before going to sleep. In these transitional moments, many people reach for their phones — not to scroll, but to play.
Millions of mobile gamers prize stress relief over winning
(Sheeka Sanahori) In the school’s car pickup line, five minutes before it starts moving. In the doctor’s office waiting room for an appointment that you’ve been heavily anticipating. In bed, just before going to sleep. In these transitional moments, many people reach for their phones — not to scroll, but to play.
According to a June 2026 survey of more than 128,000 KashKick mobile gamers, playing a mobile game is more than a way to pass the time. Stress relief and relaxation are the top reasons respondents play, beating out entertainment and fun. As KashKick reports, for many people, this means mobile games are less a simple distraction and more a coping mechanism for the daily stress of life.
A quick reset for life’s transitional moments
Most respondents identify as women, and 60% live in households that earn less than $50,000 per year. In the ranking of their reasons for playing, stress relief and relaxation topped the list, with boredom relief, entertainment and fun close behind.
The ranking reads less like a profile of a gaming hobby and more like a profile of a coping behavior.
More than half of the respondents play games daily or multiple times a day. When they reach for a mobile game, about 53% of the time it’s for a short session—usually 30 minutes or less. Where and when people play tells its own story: 58% play in bed before going to sleep and 40% play in the bathroom. These are private, solitary moments, not the times people typically plan entertainment into their day.
Coping with stress by gaming
To understand why respondents play games for stress relief more than for fun, it helps to look at who they are. Among those surveyed, 19% say they’re unemployed or looking for work, and 60% live in lower-income households. There are likely some areas of their life where they must make every dollar stretch to cover the things they need.
The survey findings coincide with research from the American Psychological Association’s 2025 Stress in America report. According to the report, 18% of men and 22% of women under age 65 rate their stress level at eight or higher on a scale of one to 10. Although the KashKick survey didn’t measure stress, respondents are mostly women and fall within the age and income groups the APA found to carry the most stress.
The APA’s report also describes loneliness as a major strain for Americans. The KashKick survey didn’t measure feelings of isolation, but 55% prefer to play alone, and 60% rarely or never discuss their gameplay with friends or family.
Overall, the survey identifies a group of people who have found a routine, low-cost approach to cope with stress. They’re not necessarily there to get the highest score. They’re playing a mobile game to help them navigate a day that, with all of life’s to-dos and challenges, could quickly feel overwhelming.
Methodology
The KashKick Gaming Habits Survey was fielded from June 8, 2026, through Aug. 10, 2026, among KashKick members in the United States who play mobile games. The Gaming Habits Survey was available to all members on KashKick’s Surveys page post-profile completion. The survey received 128,218 total responses, with question-level response counts ranging from approximately 109,793 to 128,218 depending on attrition. All findings describe KashKick mobile gamers and should not be interpreted as representative of U.S. mobile gamers overall. Industry and stress context references publicly available data from the American Psychological Association, Statista, and Newzoo.

Pediatric Cancer Goes Beyond a Victory Bell: How Research and Innovation Improve Survivorship Rates
(Feature Impact) For every tear-jerking video found online of a child ringing a bell that signifies a cancer journey victory, there are dozens, if not more, people working behind the scenes. From leading minds in cancer research to doctors, nurses and support staff, a vast network of people and decades of medical advancements make those moments possible.
In fact, in the last 10 years, the FDA approved 10 new immunotherapies and 20 molecularly targeted therapies to treat pediatric cancers, according to the American Association for Cancer Research. Those breakthroughs – and the children they impact – come with a cost, which is why Hyundai Hope on Wheels has served as a pioneer in increasing survival rates by investing $303 million in pediatric cancer research over nearly three decades.
Those funds have supported more than 1,600 grants to 210 institutions, leading to new insights into cancer biology, clinical trials and new drug development while bringing hope at all stages of a child’s cancer journey.
However, there remains work to be accomplished. According to a survey conducted by Atomik Research on behalf of Hyundai Hope on Wheels, 46% of U.S. adults believe that a child ringing a hospital bell after cancer treatment signifies the child is cancer-free and their medical journey is largely over. The reality is more nuanced than that. In fact, more than one-third of respondents said they’re not familiar with the term cancer survivorship or they have heard the term but don’t fully understand what it means.
Many health care organizations define survivorship as beginning at the time of diagnosis and continuing through treatment and beyond. According to the American Association for Cancer Research, children who survive cancer face several long-term physical and psycho-social challenges due to their cancer and treatment, including planned surgeries, additional rounds of radiation or other forms of medical treatment to address common physical challenges stemming from chemotherapy.
Survival rates continue increasing with scientific and technological breakthroughs, up from 75% to 85% in nearly three decades, representing roughly 40,000 more children surviving their diagnoses. More than 3 in 4 U.S. adults are encouraged by that progress.
For survivors, treatment is just the beginning. Research, follow-up care and long-term funding determine what comes next, and every grant funded and every survivorship program backed means more children reaching adulthood.
According to the survey, more than 80% of adults said they’re more likely to support organizations that fund survivorship services, creating opportunities to fund crucial research and support for children facing pediatric cancer. Collaboration among leading minds, made possible by funding from organizations like Hyundai Hope on Wheels, has led to the development of comprehensive approaches to help children thrive during life after cancer, including enhanced medical records, AI integration, socioemotional support and combatting long-term side effects.

A child rings the cancer bell. Here’s what that moment doesn’t show
Cancer Bell: A child who’s been treated for cancer walks down the hall of a medical facility, nurses and doctors smiling at them from all corners of the room. The child rings a bell, and everyone cheers as the kid hugs their loved ones. These heartfelt videos appear regularly across social media. What helps make each of those moments possible is decades of research and innovation. For every bell-ringing child whose video goes viral online, a longer health journey awaits.

What helps make each of those moments possible is decades of research and innovation. In the last 10 years, the Food and Drug Administration (FDA) approved 10 new immunotherapies and 20 molecularly targeted therapies to treat pediatric cancers, according to the American Association for Cancer Research.
For every bell-ringing child whose video goes viral online, a longer health journey awaits. Hyundai Hope on Wheels, which has funded pediatric cancer research for nearly three decades, commissioned a survey to understand how much Americans know about that journey.
As September marks Childhood Cancer Awareness Month, what that journey actually looks like is worth understanding. According to the survey, 46% of U.S. adults believe that a child ringing a hospital bell after cancer treatment signifies the child is cancer-free and their medical journey is largely over. The reality is more nuanced than that.
When cancer survivorship begins
Many health care organizations define survivorship as beginning at the time of diagnosis and continuing through treatment and beyond. Understanding survivorship this way helps recognize that a child’s cancer journey is about more than reaching the end of treatment. It also includes managing long-term physical, emotional and medical needs that may continue for years to come.
More than a third of U.S. adults say they’re not familiar with the term cancer survivorship or they have heard theterm but don’t fully understand what it means.
According to the American Association for Cancer Research, children who survive cancer face several long-term physical and psycho-social challenges due to their cancer and treatment. Children could face planned surgeries, additional rounds of radiation, or other forms of medical treatment to address common physical challenges stemming from chemotherapy. Every child’s medical treatment plan is different based on their specific needs, but one thing is clear: Pediatric cancer survivors need ongoing support as they navigate long-term health challenges.
Supporting children to live long, full lives
More than 3 in 4 U.S. adults are encouraged by the progress in pediatric cancer, up 5 points from last year. There’s good reason to be hopeful, too. According to the American Cancer Society, the survival rate among pediatric cancer patients has increased from 75% to 85% in nearly three decades, representing 40,000 more children surviving their cancer diagnosis.
Survival rates continue to increase thanks to breakthrough science and technology, and higher standards of care. Pediatric cancer research has led to new insights into cancer biology, clinical trials, and new drug development.
More than 8 in 10 adults say they’re more likely to support organizations that fund survivorship services, which creates more opportunities to fund crucial research and support for children facing pediatric cancer.
Methodology
Hyundai Hope on Wheels commissioned Atomik Research to conduct an online survey of 1,005 adults throughout the United States. The margin of error is +/- 3 percentage points with a confidence level of 95%. Fieldwork took place March 19-26, 2026. Atomik Research, part of 4media group, is a creative market research agency.
