In a milestone for Florida agriculture, researchers have grown and harvested wine grapes that are resistant to the main bacterial disease that has long prevented the state from establishing a large-scale wine industry.


Researchers successfully grew five grape varieties in Citra, Florida, that are resistant to Pierce’s disease, a bacterial infection that kills the vines and shrivels the grapes. The effort, led by Ali Sarkhosh, associate professor in the UF Institute of Food and Agricultural Sciences (UF/IFAS) horticultural sciences department, produced a harvest of grapes that resulted in 13 cases of wine.

While Florida has a thriving muscadine grape industry, the global market for muscadine wine is small compared to wine made from Vitis vinifera, the species of grapes behind world-famous wines such as cabernet sauvignon, sauvignon blanc and merlot. Florida is already the nation’s second-highest wine-consuming state, behind only California, with an industry valued at $15 billion in 2022. Yet most of the wines served are produced elsewhere, primarily in California, Oregon and Washington.



Sarkhosh said he hopes this research will offer a potential additional crop for muscadine grape farmers. As of 2017, there were 547 Florida vineyards, growing muscadine and hybrid grapes.


“This could be an enormous opportunity for vineyards in Florida to expand into additional types of wine for a wider market,” he said. “This could be the start of a new chapter for Florida wine.”


UF researchers worked with Château Le Coeur, a winery based in DeFuniak Springs, Florida, to make the wine from their harvest. The wine was crafted with 75% Florida-grown fruit and blended with 25% cabernet sauvignon and merlot.


The grape used in the wine collaboration is a hybrid called “Erante Noir” and was developed at the University of California, Davis. It carries the genes of sauvignon blanc and cabernet sauvignon.


John Choquer, the owner of Château Le Coeur, emphasized the potential for this collaboration.


“If we are successful in growing in the area and combating Pierce’s disease effectively, it will be a strong growth industry and emerging market for agri-tourism,” he said.


Early tastings point to a dark, fruit-forward wine. Château Le Coeur named this debut wine “Genial,” a French expression for something new and innovative.


He said he is also planting a variety of traditional wine grapes, red and white, at his vineyard. He said his winery is grateful for UF’s support and collaboration as he works to create a Florida-based traditional wine industry.


“This is not a short-term experiment,” Choquer added. “We plan to test more Pierce’s disease-resistant and traditional vinifera varieties, refine vineyard practices and build a new type of wine industry here in Florida. There will be challenges, there will be setbacks, but the potential is also so great. There is such a strong market potential here in Florida.”

Opinion: Hey Florida! Want to go to Mars? Here’s what it will do to your body

The president is eager “to plant the stars and stripes on the planet Mars.” Would you sign up for that mission? What would happen to your body in the three years you would be gone? As the United States continues to prioritize space travel, you might wonder why anyone would want to travel to Mars and whether it’s even ethical to expose humans to such extreme physiological conditions. The world is watching as the astronauts on the Boeing Starliner remain stuck in space until at least March due to a capsule malfunction. So many questions have arisen about the impacts of people spending extended periods of time in space, and we don’t have all the answers yet. However, because I study how spaceflight affects human physiology and performance, I have some ideas. The first 10 minutes of your journey will be exciting, but it’s the next months and years we really need to worry about. We have solved some of the problems but not all. After you lift off, the high g-forces will paste your body against the crew couch as you accelerate, but there’s really not too much to fear. A typical launch results in only about half the acceleration experienced by a fighter pilot in a tight turn. You might feel lightheaded, but astronauts have dealt with this for generations.

As holiday shopping season nears, UF experts warn retail theft is growing more sophisticated

With the busiest shopping season of the year approaching, new findings from the National Retail Federation’s Impact of Retail Theft and Violence 2025 report — developed by the University of Florida’s SaferPlaces Lab and the Loss Prevention Research Council — show retailers are facing increasingly complex and technology-driven threats. UF researchers say early preparation, better data and stronger collaboration will be essential as stores brace for heavier foot traffic and heightened safety risks. Despite public reports that retail theft is decreasing, Read Hayes, Ph.D., a UF research scientist and director of the LPRC at UF Innovate, said retailer surveys tell a different story: Incidents of shoplifting, organized retail crime, online fraud and other external theft continue to rise, even as some law enforcement statistics appear flat or declining. The gap, he said, reflects how much crime goes unreported or unrecorded. “Retailers have always had a difficult time reporting much of their crime, and if you look only at police data, like calls for service or arrests, it can look like retail crime is flat or even slightly down,” he said. “But when we survey retailers, who are the actual crime victims, they consistently report year-over-year increases in theft and violence.” Criminal groups are also becoming more sophisticated. Hayes said offenders are increasingly using technology to defeat protective systems, disrupt cameras and identify vulnerable stores. They also rely heavily on social media platforms such as TikTok and Reddit to coordinate attacks and share tactics. “It’s a little disconcerting how much criminals rely on social media now to scout stores, map out easy targets, learn from each other or just plain brag about how they did it,” he said. LPRC scientists monitor social media signals to help retailers and law enforcement understand emerging threats — not in real time, Hayes said, but to help build best practices organizations can use to defend themselves. Criminals continue to focus on high-demand items such as branded apparel and footwear, prompting retailers to rethink how those products are displayed and secured. Hayes said many companies are testing new approaches to better protect vulnerable merchandise without driving customers away. One example is automated self-service systems for locked items, where customers can retrieve a product by having a code sent to their phone without waiting for a store employee. Safety remains retailers’ top concern, Hayes said. LPRC’s latest report, developed in collaboration with the security technology company Verkada, found that frontline retail workers report feeling less safe than ever, a trend that typically intensifies during the holiday rush. Rising incidents of in-store violence, limited law enforcement support in some areas and increased guest-related confrontations are pushing retailers to reassess how they protect both employees and customers. “Nothing is more important than protecting the frontline retail associates who keep this industry running,” Hayes said. “This report helps reinforce what retailers need to do to ensure those workers feel safe.” LPRC teams are also studying ways to improve safety beyond store walls, testing parking lot technologies, including license plate readers and flashing deterrent systems designed to discourage potential offenders and reassure law-abiding shoppers. At the federal level, Hayes said he and partners across the country are urging Congress to pass a bill to address organized retail crime and establish a centralized platform for reporting retail theft threats. As the holiday season approaches, Hayes said the need for evidence-based solutions has never been clearer. “Retailers are under pressure to keep their stores safe, welcoming and competitive,” Hayes said. “The more we can understand offender behavior, customer expectations and emerging technologies, the better we can help retailers, communities and law enforcement reduce harm.” The LPRC, headquartered at UF Innovate, brings together more than 200 major retailers, technology companies and public safety agencies to conduct research that strengthens store safety, reduces loss and enhances the customer experience.

AI Can’t Replace Therapists – But It Can Help Them

For a young adult who is lonely or just needs someone to talk to, an artificial intelligence chatbot can feel like a nonjudgmental best friend, offering encouragement before an interview or consolation after a breakup. AI’s advice seems sincere, thoughtful and even empathic – in short, very human. But when a vulnerable person alludes to thoughts of suicide, AI is not the answer. Not by itself, at least. Recent stories have documented the heartbreak of people dying by suicide after seeking help from chatbots rather than fellow humans. In this way, the ethos of the digital world – sometimes characterized as “move fast and break things” – clashes with the health practitioners’ oath to “first, do no harm.” When humans are being harmed, things must change. As a researcher and licensed therapist with a background in computer science, I am interested in the intersection between technology and mental health, and I understand the technological foundations of AI. When I directed a counseling clinic, I sat with people in their most vulnerable moments. These experiences prompt me to consider the rise of therapy chatbots through both a technical and clinical lens. AI, no matter how advanced, lacks the morality, responsibility and duty of care that humans carry. When someone has suicidal thoughts, they need human professionals to help. With years of training before we are licensed, we have specific ethical protocols to follow when a person reveals thoughts of suicide. Read the full article from US News & World Report here
