Ask an Expert: Augusta University's Gokila Dorai, PhD, talks Artificial Intelligence

Artificial Intelligence is dominating the news cycle. There's a lot to know, a lot to prepare for and also a lot of misinformation or assumptions that are making their way into the mainstream coverage. Recently, Augusta University's Gokila Dorai, PhD, took some time to answer some of the more important question's she's seeing being asked about Artificial Intelligence. Gokila Dorai, PhD, is an assistant professor in the School of Computer and Cyber Sciences at Augusta University. Dorai’s area of expertise is mobile/IoT forensics research. She is passionate about inventing digital tools to help victims and survivors of various digital crimes. View her profile here Q. What excites you most about your current research in digital forensics and AI? "I am most excited about using artificial intelligence to produce frameworks for practitioners make sense of complex digital evidence more quickly and fairly. My research combines machine learning with natural language processing incorporating a socio-technical framework, so that we don’t just get accurate results, but also understand how and why the system reached those results. This is especially important when dealing with sensitive investigations, where transparency builds trust." Q. How does your work help address today’s challenges around cybersecurity and data privacy? "Everyday life is increasingly digital, our phones, apps, and online accounts contain deeply personal information. My research looks at how we can responsibly analyze this data during investigations without compromising privacy. For example, I work on AI models that can focus only on what is legally relevant, while filtering out unrelated personal information. This balance between security and privacy is one of the biggest challenges today, and my work aims to provide practical solutions." Q. What role do you see artificial intelligence playing in shaping the future of digital investigations? "AI will be a critical partner in digital investigations. The volume of data investigators face is overwhelming, thousands of documents, chat messages, and app logs. AI can help organize and prioritize this information, spotting patterns that a human might miss. At the same time, I believe AI must be designed to be explainable and resilient against manipulation, so investigators and courts can trust its findings. The future isn’t about replacing human judgment, but about giving investigators smarter tools." Q. What is one misconception people often have about cybersecurity or digital forensics? "A common misconception is that digital forensics is like what you see on TV, instant results with a few keystrokes. In reality, it’s a painstaking process that requires both technical skill and ethical responsibility. Another misconception is that cybersecurity is only about protecting large organizations. In truth, individuals face just as many risks, from identity theft to app data leaks, and my research highlights how better tools can protect everyone."

How to respond when your teen rebels

Why do some rebellious teenagers shun parental warnings about their behavior while others take them to heart? University of Rochester psychologist Judith Smetana has devoted her career to unpacking that question. Her research reveals that parents who live out their values — and take the time to understand the perspective of their teenagers — have the most success at positively shaping adolescent behavior. Smetana’s latest study, published in the Journal of Youth and Adolescence, shows that when parents “walk the walk” and model their values consistently, teens perceive rules and warnings as supportive guidance rather than controlling commands. But that alone won’t stop all risky teenage behavior. What really works, Smetana’s research finds, is “perspective-taking”: when parents try to understand their child’s feelings and the reasons for them. Smetana is widely cited for her expertise on moral development, autonomy, and parent-teen conflict — and how these dynamics shape young people’s lives. Connect with her by clicking on her profile.

Swimming in the deep: MSU research reveals sea lamprey travel patterns in Great Lakes waterways

Why this matters: Invasive sea lampreys prey on most species of large Great Lakes fish such as lake trout, brown trout, lake sturgeon, lake whitefish, ciscoes, burbot, walleye and catfish. These species are crucial to Great Lakes ecosystems and to the region’s fishing industry. Understanding how sea lampreys migrate can inform management and conservation strategies, such as developing methods to catch the invasive fish that don’t involve dams, which reduce river connectivity, or lampricide, a pesticide that some communities and groups prefer not to use. The Great Lakes fishing industry is worth $7 billion and provides 75,000 jobs to the region. Reducing the amount of sea lamprey in waters is crucial for the industry’s well-being and the economic vitality of the Great Lakes. How do you catch an invasive fish that’s solitary, nocturnal and doesn't feed on bait? Researchers in the Michigan State University College of Agriculture and Natural Resources are one step closer to figuring it out. In a study published in the Journal of Experimental Biology and funded by the Great Lakes Fishery Commission, Kandace Griffin, a fisheries and wildlife doctoral student, and Michael Wagner, professor in the MSU Department of Fisheries and Wildlife, found that sea lampreys — a parasitic fish considered an invasive species in the Great Lakes region of the U.S. — follow a clear pattern of staying in the deepest parts of a river. These findings are important for informing sea lamprey management strategies, conservation of fish species native to the Great Lakes and protecting the region’s $7 billion fishing industry and the 75,000 jobs it provides. “We wanted to know how sea lampreys are making their movement decisions when migrating,” Griffin said. “Are they guided by certain environmental cues? Are they moving through areas that are safer? How can we potentially exploit those decisions or maybe manipulate them into going somewhere that they don’t want to go, like pushing them into a trap.” The primary methods used to control sea lamprey are dams that block them from entering waterways and lampricide, a species-specific pesticide that targets lamprey larvae. “Dams create a lot of challenges for conserving river ecosystems: They block all the other fish that are moving up and down in the system. Even though lampricide is proven to be safe and effective, there are communities that are uncomfortable with its use going into the future,” Wagner said. “Figuring out the right way to fish sea lamprey would decrease its population, lower reproduction rates and provide managers with the opportunity to match their control tactics to the community’s needs.” To track lamprey movements, Griffin and Wagner used a method called acoustic telemetry, which involved using sound emitted from a surgically implanted tag to track the movement of 56 sea lampreys in the White River near Whitehall, Michigan. Griffin likened acoustic telemetry to GPS. “There’s a tag that emits sound and has a unique transmission with a unique identification code, so I know exactly which fish is going where,” she said. “The receivers are listening for that sound and then calculating the time it reaches each receiver. We used this information to triangulate the position of the sea lamprey and analyzed it to find out how they’re using the river’s environmental traits to make decisions on where to swim.” Of the 56 lampreys studied, 26 of them (46%), consistently chose the deepest quarter of the river. “For nearly 20 years we have been discovering how sea lampreys migrate along coasts and through rivers. Now, thanks to Kandace’s work, we know where their movement paths come together near a riverbank — the perfect place to install a trap or other fishing device,” Wagner said. “That knowledge can be used to find similar sites across the Great Lakes basin.” Right now, a fishing device designed to catch bottom-swimming, solitary, nonfeeding, nocturnal sea lamprey doesn’t exist. However, Wagner notes there are places around the world — including Indigenous communities in the U.S. — where people have fished migratory lampreys of various species for hundreds of years and could help inform the creation of such a mechanism. “We have recently had a proposal funded to scour the Earth in search of knowledge, both scientific and traditional, about how to capture migrating lampreys and similar fishes,” Wagner said. “We want to talk with the communities of people who have histories fishing these animals and use this information, along with other data we’ve gathered, to conceive a device that could be used to fish sea lampreys.” Griffin views the new intel on lamprey migration patterns as a way to inform fishing practices to complement some of the existing control methods. “Hopefully, we can use this as a supplemental control method to the use of the barriers or dams,” she said. “We have societal pressure to remove barriers to enhance river connectivity, and some barriers are failing. Open water trapping is another way that we could try to still combat the invasive sea lamprey problem here but also promote river connectivity and other conservation goals for other species.” Wagner shares the same perspective. “When a community, or the Great Lakes Fishery Commission, or the governments of Canada and the U.S. come in and say, ‘We’d really rather be able to control this river with something other than lampricide,’ we want to be able to be able to provide 360-degree solutions that specify where to fish, when to fish and how to fish using fully prototyped and tested equipment,” he said. “We want our science to help solve real-world problems.”

Professor Roslyn Bill selected for the inaugural cohort of the Big if True Science accelerator

Professor Roslyn Bill is the director of Aston Institute for Membrane Excellence (AIME) The Big if True Science (BiTS) accelerator aims to bridge the gap between cutting-edge lab science and multi-million-dollar collaborative projects Professor Bill’s research is focused on the brain’s plumbing system and developing drugs against traumatic brain injury and cognitive decline. Professor Roslyn Bill, director of Aston Institute for Membrane Excellence (AIME), has been selected as an inaugural fellow of the new Big if True Science (BiTS) accelerator. BiTS was set up by a non-profit organisation, Renaissance Philanthropy, to support its scientist and innovator fellows in developing groundbreaking research initiatives and equip them with the tools, skills, and networks needed to design high-impact, collaborative research programmes and technical projects with multi-million-dollar budgets beyond their own laboratories. The first cohort of 12 fellows was selected after a highly competitive process. The cohort represents diverse fields including neuroscience, environmental engineering, biomedical research, and materials science. Over a 15-week period, they will transform their breakthrough concepts into fundable eight-figure R&D programmes, before pitching their ideas to funders on 10 December 2025. Professor Bill’s research focuses on the glymphatic system, the brain’s ‘plumbing’ system, which facilitates the movement of fluid and clears waste products. Water moves in and out of brain cells through tiny protein channels in the cell membrane called aquaporins. Uncontrolled water entry, for example, after a head injury, can cause catastrophic swelling and severe brain injuries of the type suffered by racing driver Michael Schumacher after a skiing accident. When the flow is impeded, for example, as we age, waste products can build up, leading to diseases like Alzheimer’s. In 2020, Professor Bill was lead author on a paper published in the prestigious journal Cell on how the flow of water through aquaporin-4 is controlled. She is now researching drugs to affect this process, which could have a huge impact on the treatment of traumatic brain injury and cognitive decline. Professor Bill said: “Every year, tens of millions of people are affected by injuries to their brains. Every three seconds, someone in the world develops dementia. There are no medicines that can fix these terrible conditions. Being an inaugural member of BiTS is a great honour, and I am delighted to be in the company of truly inspiring people. This exciting programme offers hope to patients for whom no medicines are available!”

First scientific paper on 3I/ATLAS interstellar object

When the news started to spread on July 1, 2025, about a new object that was spotted from outside our solar system, only the third of its kind ever known, astronomers at Michigan State University — along with a team of international researchers — turned their telescopes to capture data on the new celestial sighting. The team rushed to write a scientific paper on what they know so far about the object, now called 3I/ATLAS, after NASA’s Asteroid Terrestrial-impact Last Alert System, or ATLAS. ATLAS consists of four telescopes — two in Hawaii, one in Chile and one in South Africa — which automatically scans the whole sky several times every night looking for moving objects. MSU’s Darryl Seligman, a member of the scientific team and an assistant professor in the College of Natural Science, took the lead on writing the paper. “I heard something about the object before I went to bed, but we didn’t have a lot of information yet,” Seligman said. “By the time I woke up around 1 a.m., my colleagues, Marco Micheli from the European Space Agency and Davide Farnocchia from NASA’s Jet Propulsion Laboratory, were emailing me that this was likely for real. I started sending messages telling everyone to turn their telescopes to look at this object and started writing the paper to document what we know to date. We have data coming in from across the globe about this object.” The discovery Larry Denneau, a member of the ATLAS team reviewed and submitted the observations from the European Southern Observatory's Very Large Telescope in Chile shortly after it was observed on the night of July 1. Denneau said that he was cautiously excited. “We have had false alarms in the past about interesting objects, so we know not to get too excited on the first day. But the incoming observations were all consistent, and late that night it looked like we had the real thing. “It is especially gratifying that we found it in the Milky Way in the direction of the galactic center, which is a very challenging place to survey for asteroids because of all the stars in the background,” Denneau said. “Most other surveys don't look there.” John Tonry, another member of ATLAS and professor at the University of Hawaii, was instrumental in design and construction of ATLAS, the survey that discovered 3I. Tonry said, “It's really gratifying every time our hard work surveying the sky discovers something new, and this comet that has been traveling for millions of years from another star system is particularly interesting.” Once 3I/ATLAS was confirmed, Seligman and Karen Meech, faculty chair for the Institute for Astronomy at the University of Hawaii, both managed the communications flow and worked on getting the data pulled together for submitting the paper. “Once 3I/ATLAS was identified as likely interstellar, we mobilized rapidly,” Meech said. “We activated observing time on major facilities like the Southern Astrophysical Research Telescope and the Gemini Observatory to capture early, high-quality data and build a foundation for detailed follow-up studies.” After confirmation of the interstellar object, institutions from around the world began sharing information about 3I/ATLAS with Seligman. What scientists know about 3I/ATLAS so far Though data is pouring in about the discovery, it’s still so far away from Earth, which leaves many unanswered questions. Here’s what the scientific team knows at this point: It is only the third interstellar (meaning from outside our solar system) object to be detected passing through our solar system. It’s potentially giving off gas like other comets do, but that needs to be confirmed. It’s moving really fast at 60 kilometers per second, or 134,000 miles per hour, relative to the sun. It’s on an orbital path that is shaped like a boomerang or hyperbola. It’s very bright. It’s on a path that will leave our solar system and not return, but scientists will be able to study it for several months before it leaves. The James Webb Space Telescope and the Hubble Space Telescope are expected to reveal more information about its size, composition, spin and how it reacts to being heated over the next few months. “We have these images of 3I/ATLAS where it’s not entirely clear and it looks fuzzier than the other stars in the same image,” said James Wray, a professor at Georgia Tech. “But the object is pretty far away and, so, we just don’t know.” Seligman and his team are specifically interested in 3I/ATLAS’s brightness because it informs us about the evolution of the coma, a cloud of dust and gas. They’ve been tracking it to see if it has been changing over time as the object moves and turns in space. They also want to monitor for sudden outburst events in which the object gets much brighter. “3I/ATLAS likely contains ices, especially below the surface, and those ices may start to activate as it nears the sun,” Seligman said. “But until we detect specific gas emissions, like H₂O, CO or CO₂, we can’t say for sure what kinds of ice or how much are there.” The discovery of 3I/ATLAS is just the beginning. For Tessa Frincke, who came to MSU in late June to begin her career as a doctoral student with Seligman, having the opportunity to analyze data from 3I/ATLAS to predict its future path could lead to her publishing a scientific paper of her own. “I’ve had to learn a lot quickly, and I was shocked at how many people were involved,” said Frincke. “Discoveries like this have a domino effect that inspires novel engineering and mission planning.” For Atsuhiro Yaginuma, a fourth-year undergraduate student on Seligman’s team, this discovery has inspired him to apply his current research to see if it is possible to launch a spacecraft from Earth to get it within hundreds of miles or kilometers to 3I/ATLAS to capture some images and learn more about the object. “The closest approach to Earth will be in December,” said Yaginuma. “It would require a lot of fuel and a lot of rapid mobilization from people here on Earth. But getting close to an interstellar object could be a once-in-a-lifetime opportunity.” “We can’t continue to do this research and experiment with new ideas from Frincke and Yaginuma without federal funding,” said Seligman, who also is a postdoctoral fellow of the National Science Foundation. Seligman and Aster Taylor, who is a former student of Seligman’s and now a doctoral candidate in astronomy and astrophysics and a 2023 Fannie and John Hertz Foundation Fellow, wrote the following: “At a critical moment, given the current congressional discussions on science funding, 3I/ATLAS also reminds us of the broader impact of astronomical research. An example like 3I is particularly important to astronomy — as a science, we are supported almost entirely by government and philanthropic funding. The fact that this science is not funded by commercial enterprise indicates that our field does not provide a financial return on investment, but instead responds to the public’s curiosity about the deep questions of the universe: Where did we come from? Are we alone? What else is out there? The curiosity of the public, as expressed by the will of the U.S. Congress and made manifest in the federal budget, is the reason that astronomy exists.” In addition to MSU, contributors to this research and paper include European Space Agency Near-Earth Objects Coordination Centre (Italy), NASA Jet Propulsion Laboratory/Caltech (USA), University of Hawaii (USA), Auburn University (USA), Universidad de Alicante (Spain), Universitat de Barcelona (Spain), European Southern Observatory (Germany), Villanova University (USA), Lowell Observatory (USA), University of Maryland (USA), Las Cumbres Observatory (USA), University of Belgrade (Serbia), Politecnico di Milano (Italy), University of Michigan (USA), University of Western Ontario (Canada), Georgia Institute of Technology (USA), Universidad Diego Portales, Santiago (Chile) and Boston University (USA).

LSU, FUEL, Syngenta Partner to Develop Low-cost Digital Twins for Chemical Processing Facilities

Derick Ostrenko and Jason Jamerson, faculty in the LSU College of Art & Design, along with engineering advisor David Ben Spry, are pioneering a new approach to industrial innovation using digital twins. The effort is supported by a $217,403 use-inspired research and development (UIRD) award from Future Use of Energy in Louisiana (FUEL). Digital twins are highly detailed, virtual replicas of physical assets. The technology is used in engineering to enhance efficiency, safety, and training; however, their creation often requires costly specialized hardware, proprietary software, and engineering-intensive workflows. “This initiative not only advances digital twin technology but also highlights the interdisciplinary power of design and engineering,” FUEL UIRD Director Ashwith Chilvery said. “By applying creative tools in an industrial setting, we’re demonstrating new ways to lower costs and expand access to advanced digital infrastructure.” The collaborative effort between LSU, FUEL, and Syngenta aims to reduce costs by applying techniques more commonly used in the entertainment industry, leveraging free and open-source software and consumer-grade hardware, such as gaming PCs and digital cameras. Most of the work will be conducted by digital art students skilled in 3D modeling and video game production, offering a cost-effective alternative to traditional engineering services. “3D artists and game developers bring both technical expertise and creative vision that can add significant value when paired with traditional engineering approaches,” Spry said. “We’re eager to demonstrate how this talent pool can help accelerate digital transformation in industry.” “Working with an innovative company like Syngenta to advance digital twins for chemical manufacturing is an outstanding opportunity for our researchers and students, and we’re proud of the techniques and talent we’ve developed at LSU. FUEL’s support of digital twin development for the energy and chemical sectors helps build this technology and unique artistry in Louisiana, for our industries, and for the rest of the nation.” - Greg Trahan, LSU Assistant Vice President of Strategic Research Partnerships In addition to producing a high-fidelity digital twin of a process unit within an active chemical manufacturing facility, the project will deliver a virtual reality application that allows immersive interaction with the 3D model. Future extensions may include augmented reality overlays of physical equipment or integration of live process data for real-time monitoring and troubleshooting. The ultimate outcome of the project is a validated workflow that reduces the cost of producing digital twins by a factor of at least five compared to conventional engineering methods. This breakthrough has the potential to redefine digital infrastructure for the chemical processing industry, making it more accessible, scalable, and adaptable to future needs.

MSU researchers: Young athletes should take a cross-training vacation for better performance, health

Why this matters: MSU researchers say that young athletes who specialize in just one sport experience more injuries and injury-related surgeries. Switching sports for one season a year, or roughly three months, can keep young athletes safer and provide a better outlook for their long-term health. This information is important for parents, coaches, young athletes and their health practitioners as they make decisions about upcoming sports seasons. Some professional football players practice ballet. An NCAA champion runner also swims. An Olympic gold medal speed skater does six-hour biking sessions. According to researchers from Michigan State University, these athletes are ahead of the game because cross-training can help prevent injury in youth athletes. Nathan Fitton, associate professor of orthopedics in the MSU College of Osteopathic Medicine, chief medical information officer for MSU Health Care, and MSU Athletics team physician; Jared Lutsic, MSU College of Osteopathic Medicine alumni and orthopedic surgery resident at Henry Ford Warren; and others studied the effects of sport specialization on collegiate athletes. Their findings were recently published in the Clinical Journal of Sport Medicine and reveal a direct association between the intensity of sport specialization and incidence of injuries while as a college athlete. “We expected to learn that highly specialized athletes would have higher injury rates,” Fitton said. “What’s alarming is a statistically significant increase in surgical procedures after an injury. We found that the more specialized an athlete was, the more likely they were to need surgery to correct an injury. This was true for male and female athletes.” “There are lifelong implications for youth sports injuries,” he added. “Injured athletes don’t always return to their pre-injury state. In the short term, this may mean they don’t get back to the sport at a level where they want to be. Longer term, we see arthritis from trauma to joints at an earlier age than would be expected. And we see 30- and 35-year-olds who need additional surgeries or lifestyle modifications to recover from an injury they experienced as a youth athlete.” In the survey, NCAA Division I, II and III athletes were asked about their sports participation, specialization, injuries, recovery periods and treatment methods. Findings showed that highly specialized athletes were more likely to report injuries and, of those who said they had been injured, more than half reported a reinjury. “We asked college athletes about their specialization status and learned that those who had a history of being highly specialized in high school got injured more frequently in college and had more severe injuries,” Lutsic said. “Parents, physicians and coaches should consider this when advising student athletes.” Crosstrain for better performance and lower risk of injury “Athletes can still be very committed to a single sport and reduce their risk of injury by playing just one other sport for three months,” Fitton explained. “Cross-training is like rotating the tires on your car. You’ll get longer use and better performance when tires are regularly rotated. For our bodies, diversification of movement reduces the risk of injury and helps maintain healthy functioning.” Fitton says that other activities, like dance class or participating in a school play, can offer the break young athletes need. Even taking a day or two a week to do something that uses different muscle groups would be beneficial, he added.

University of Delaware secures $13.1M grant to transform Alzheimer’s research and prevention

A new five-year $13.1 million grant will greatly expand the ability of University of Delaware researchers to pursue ways to prevent and treat Alzheimer's disease. The gift from the Delaware Community Foundation (DCF) is one of the largest in state history for Alzheimer’s research. UD's Christopher Martens called the grant "transformational," as it will support the expansion of a statewide prevention study, enable the purchase of a state-of-the-art MRI machine and drive discovery of new diagnostic tools and treatments. “It will also help grow the number of researchers in Delaware focused on Alzheimer’s disease, promoting an interdisciplinary approach." said Martens, director of UD's Delaware Center for Cognitive Aging Research (DECCAR) and professor of kinesiology and applied physiology in the College of Health Sciences. Bringing together researchers from multiple fields to collaborate on a critical challenge like Alzheimer’s disease is a key strength of the University of Delaware, said Interim President Laura Carlson. “Every one of us has a family member or friend who has been deeply affected by Alzheimer’s. I’m proud that UD is working better to understand this terrible disease and partnering with others throughout the state to work on its prevention, diagnosis and treatment,” Carlson said. “We are grateful to the Delaware Community Foundation for their support, which allows us to escalate our research and expand our community outreach.” “No one has to look very far afield to witness and understand the tragedy of Alzheimer’s, and the research supported by this grant will help UD researchers come ever-closer to uncovering life-improving and life-saving solutions,” said Stuart Comstock-Gay, President and CEO of the Delaware Community Foundation (DCF). “The grant was provided through the generosity of late Paul H. Boerger, who made a substantial legacy gift to the fund he had established at the DCF in his lifetime, and his foresight will help so many.” The gift is aimed at achieving the following goals: • Tracking Alzheimer’s risk over time – Expanding Delaware’s largest study of brain aging from 100 to 500 participants to uncover who develops dementia and why. • A simple blood test for early detection – Developing a first-of-its-kind test that could diagnose Alzheimer’s years earlier than current methods. • Cutting-edge brain imaging – Installing a $3.2 million MRI machine on UD’s STAR Campus to reveal hidden brain changes linked to memory loss. • Spotting the earliest warning signs – Exploring how subtle shifts in language and menopause-related hormone changes may predict Alzheimer’s risk. • Fueling prevention and cures – Creating powerful data and tools that will accelerate new treatments and bring researchers closer to stopping Alzheimer’s.
