  • Virtual reality a ‘safe space’ for youth counselling: Brock-Pathstone research

    MEDIA RELEASE – SEPTEMBER 11, 2025 – R0101

    For many children and teens, virtual reality (VR) headsets are a gateway to immersive video game worlds.

    But Nicole Luke thinks they could also open the door to better mental health.

    “There’s a different kind of experience in this type of space. VR is a tool that can give anxious youth a safe space to express themselves and test out new behaviours,” says the Brock University Assistant Professor of Applied Disabilities Studies.

    Luke and her team partnered with Pathstone Mental Health — which offers a range of services tailored to children, youth and families in Niagara — to study the use of VR in cognitive behaviour therapy (CBT) counselling sessions for children and adolescents. 

    Pathstone CEO Shaun Baylis says the organization aims to engage in research that develops “innovative, evidenced-based, effective and high-quality methods of service delivery.”

    “We are further committed to reducing barriers to services and saw this project as meeting those priorities,” he says. “We are thrilled to partner in research with Brock around VR therapy as a way of growing the field for our community and beyond.” 

    Luke’s team included then-Applied Disability Studies master’s students Gifty Owusu (MA ’24) and Qi Wan (MADS ’23) as well as Samantha Allcock, System Performance Co-ordinator at Pathstone. The group also worked with XpertVR, a VR company Luke has collaborated with on previous research.

    The study involved seven Pathstone clients ranging from eight to 16 years old receiving in-person CBT treatment for anxiety and two mental health therapists with experience delivering CBT to adolescents.

    CBT is a type of psychotherapy where negative thoughts and feelings are challenged and replaced with helpful thinking patterns, leading to positive behaviour change. Therapists assign exercises between sessions for clients to achieve these goals.

    The team outfitted clients and therapists with head-mounted display devices consisting of headsets and hand controllers along with software called Engage to support single-player and multi-player access to virtual environments.

    After being trained in how to use the technology, clients and therapists conducted CBT-VR sessions lasting 10 to 20 minutes at a time taking place over a time period ranging from six weeks to a school year. 

    Pre- and post-study questionnaires surveyed participants’ experiences and satisfaction levels with using VR in counselling sessions.

    Luke says feedback from the children and teens was largely positive.

    “We did see some differences in how clients behaved with the counsellors and other people in the VR setting compared to real life,” she says. “The youth were more forthcoming and engaged — they talked and interacted more than they did in real life.”

    One possible reason for this, says Luke, could be clients were allowed to construct their own avatars to represent themselves. Some clients created a figure closely resembling themselves while others chose an object to represent them. 

    The therapist also created an avatar, so at some points, the two avatars would interact.

    “This configuration creates a bit of distance or anonymity,” says Luke. “Nobody’s looking at you physically, they’re looking at your avatar, so that takes the pressure off the clients and makes a safe space for them to try something new or challenge themselves.”

    Eventually the client and therapist would reconnect with each other face to face to discuss homework assignments and other issues.

    The therapists initially felt intimidated by the new technology but soon learned to adapt, Luke says.

    Baylis says Pathstone’s clients “were interested and engaged in this method of treatment.” 

    “As a therapist, it offered challenges and opportunities to extend the therapy space,” he says. “It was exciting to participate and be part of the possibilities this offers the therapy experience.”

    The team is in the process of compiling their results for an academic journal.

    The study, “Delivery of Mental Health Services for Ontario Youth Using CBT in Virtual Reality,” was funded by grants from TD Bank and the Knowledge Institute on Child and Youth Mental Health and Addictions, a department of the Ottawa-based Children’s Hospital of Eastern Ontario.

    This work builds on the foundation of a 2019 Memorandum of Understanding between Brock and Pathstone Mental Health, which formalized a shared commitment to advancing mental health research, education and community outreach across Niagara.

  • Unearthed Mars minerals provide strong evidence of potential ancient life on Red Planet 

    MEDIA RELEASE – SEPTEMBER 10, 2025 – R0100

    New research supported by Brock University Earth Sciences professors has uncovered findings that could provide the clearest sign of ancient life ever found on Mars.

    As members of the Mars 2020 PIXL Instrument Science Team, Mariek Schmidt and Tanya Kizovski were part of an international effort that discovered a potential “biosignature” in a sample collected by NASA’s Perseverance Mars rover.

    Biosignatures are a substance, feature or pattern that could suggest the presence of either past or present life.

    While further study is required to definitively confirm the findings, scientists have indicated that a biological explanation for features identified within the rocks cannot be dismissed.

    “This is the most significant finding to date by the Perseverance rover,” says Schmidt, a Co-Investigator on the Mars 2020 PIXL Instrument Science Team. “When we sent Perseverance to Jezero Crater, we were making an educated guess that we’d find evidence of past life. Now we know that the suspicions were possibly confirmed. Once the samples are hopefully brought to Earth, we will be able to definitively confirm it.”

    The findings were announced during a media conference hosted by NASA on Wednesday, Sept. 10. The discovery is also the subject of a peer-reviewed paper, co-authored by Schmidt and Kizovski, recently published in Nature.

    Called “Sapphire Canyon,” the sample was collected in July 2024 from a set of reddish, clay-rich mudstones found on the edges of Mars’ Neretva Vallis, a river valley created by water that once flowed into the planet’s Jezero Crater more than three billion years ago. The Perseverance Rover has been exploring this area since February 2021.

    Through detailed analysis, the research team identified a series of iron-, sulfur- and phosphorus-bearing minerals within a collection of outcrops informally named ‘Bright Angel,’ located in the northern margin of Neretva Vallis.

    Two minerals appeared to have formed because of chemical reactions between mud making up the ‘Bright Angel’ outcrops and organic matter: vivianite, an iron phosphate mineral, and greigite, an iron sulfide mineral.

    Kizovski says the textural relationships between these minerals and their association with organics provides strong evidence of a potential biosignature.

    Using the Planetary Instrument for X-Ray Lithochemistry (PIXL), which rapidly measures elemental chemistry on Mars remotely from Earth, Schmidt and Kizovski contributed to the textural, chemical, spectral and analyses on the sample and related outcrops.

    “When we’re trying to figure out if an environment was potentially habitable or if there are biosignatures present, we look at the minerals that formed from that environment, their textural relationships, and then tease back the conditions that would have caused these minerals to form,” Kizovski, a PIXL Science Team Associate Researcher, says. “The data from the PIXL was crucial for this work.”

    The team identified fine-grained outcrops in the ‘Bright Angel’ region and upon closer inspection, unusual features were discovered on the surfaces of the mudstones.

    “It looked like nothing we had seen previously because there are sub-millimetre spots that are lighter in tone in the centre with a dark ring of reduced, iron-containing phosphates around them. The team called them ‘leopard spots,’” says Schmidt. “Knowing that organics and reduced iron can be associated with one another, and that on Earth, these sorts of textures can be attributed to life, it was a very exciting discovery.”

    In prior research conducted within Jezero Crater, Kizovski and Schmidt also identified multiple iron phosphates related to the mineral vivianite in a different outcrop called Onahu. This provided evidence that many of the materials and energy sources needed for conditions that may support life could have once existed within Mars’ Jezero Crater.

    A representative sample that may contain iron phosphate minerals was collected from an outcrop on Mars, about 30 metres from Onahu on sol 822 of the Perseverance mission.

    “The identification of iron phosphates in Onahu is not considered a potential biosignature as these minerals can form without biological inputs, they are not associated with organics, and they do not have the same textural context as the iron phosphates identified within ‘Bright Angel,’” says Kizovski. “However, finding evidence of vivianite on Mars is really exciting on its own because it could have originally precipitated in conditions favourable to potential ancient life on the planet, which includes the presence of phosphorus, water, low temperature and a neutral pH.”

    Kizovski and Schmidt’s contributions to this work were funded through the Canadian Space Agency. Kizovski completed part of this research while she was a postdoctoral fellow at Brock, under the supervision of Schmidt, and working as the former Associate Curator of Mineralogy at the Royal Ontario Museum.
