New study suggests Florida Chagas disease transmission

Researchers from the University of Florida Emerging Pathogens Institute and Texas A&M University gathered their resources to investigate the potential of vector-borne transmission of Chagas in Florida. The 10-year-long study, published in the Public Library of Science Neglected Tropical Diseases, used data from Florida-based submissions, as well as field evidence collected from 23 counties across Florida. Chagas disease is considered rare in the United States. Since it is not notifiable to most state health departments, it is quite difficult to know exactly how many cases there are and how frequently it’s transmitted. Chagas disease is caused by the protozoan parasite Trypanosoma cruzi. Nuisance blood-sucking insects known as kissing bugs spread the parasite to humans when exposure to their feces penetrates the mucus membranes, breaches the skin or gets orally ingested. Interestingly, it is believed that most companion animals, like dogs and cats, acquire the parasite from eating the kissing bug itself. The first record of kissing bugs, scientifically known as Triatoma sanguisuga, harboring T. cruzi in Florida was from an insect in Gainesville in 1988. However, kissing bugs have been calling the state home for far longer than humans have. Currently, there are two known endemic species of kissing bugs in the Sunshine State: Triatoma sanguisuga, the species invading homes, and the cryptic species Paratriatoma lecticularia, which live primarily in certain Floridan ecosystems but were not found in this study.

Villanova's Héctor Varela Rios, PhD, Comments on Bad Bunny's Super Bowl Performance, "Unapologetic" Swagger

On February 8, 2026, 120 million-plus viewers worldwide are expected to tune into Super Bowl LX. However, the battle on the gridiron will be a secondary attraction for many, especially those from Puerto Rico and of Puerto Rican descent (colloquially known as "Boricuas"). Their attention will be focused on this year's halftime show, headlined by Bayamón-born rapper and producer Bad Bunny. Renowned for songs like "Yo Perreo Sola," "La Canción" and "Me Porto Bonito," the pop sensation is expected to bring a distinctive Latin American flair to his set, representing Puerto Rican culture and creativity to an audience unlike any other. Héctor Varela Rios, PhD, the Raquel and Alfonso Martínez-Fonts Endowed Assistant Professor in Latin American Studies at Villanova University, specializes in popular culture and writes extensively on the Boricua community, to which he himself belongs. From his perspective, Bad Bunny's upcoming performance in the Super Bowl halftime show marks "a high point for Puerto Rican pride," both within the U.S. territory and across the globe. "He is not the first Super Bowl performer to claim Puerto Rican ancestry—Jennifer Lopez performed alongside Colombia-born Shakira in 2020—but he is the first island-born Puerto Rican to perform," says Dr. Varela Rios. "At this moment, he is our brightest superstar and absolutely adored throughout Latin America and the world." To the professor's point, Bad Bunny is among the most successful musical acts touring today, having notched more than 7 million records sold, four diamond plaques and 11 platinums all before the age of 32. His popularity has not come at the expense of his art, either, with the rapper having won six Grammy Awards over the course of his career—including three for his latest album, "Debí Tirar Más Fotos." According to Dr. Varela Rios, Bad Bunny's widespread appeal and critical acclaim can be traced to his authenticity, courage and swagger. Singing in Spanish, making deep-cut cultural references and broaching sensitive, seemingly taboo topics, the Latin American pop star has effectively built a following by unabashedly embracing his own identity. (Perhaps tellingly, he titled his second album "Yo Hago Lo Que Me Da La," or "I Do Whatever I Want.") "Bad Bunny is proud of his Caribbean roots and keenly aware of the history of Puerto Rico, particularly since the U.S. took control, which influences his work," says Dr. Varela Rios. "In addition, he is very unapologetic about the content of his lyrics and performing style. It goes beyond mere shock with him; he relishes challenging assumptions of what being an artist should be or needs to be in order to 'sell records.'" While this daring approach has netted Bad Bunny a number of accolades and a devoted legion of fans, it has not been without its share of detractors. Still, on the biggest stages and under the brightest lights, the celebrated artist has shown no inclination to shy away from controversy. Dr. Varela Rios predicts the pop star's Super Bowl act will be no different. "If people took exception to Kendrick Lamar last year, be warned: Bad Bunny will blow you away," says the professor. "I would not be surprised to see thinly veiled, or just unveiled, political content. "That said, Bad Bunny is a businessman, and one of the best I've ever seen. This is an artist who knows what to do and how to do it, and when the Super Bowl halftime show's lights go down, his performance will certainly be remembered."

The Double-Edged Scroll: Why Passive Screen Time Drains You More Than Active Use

Most conversations about “screen time” focus on hours. But newer research and what clinicians see in practice suggest how you use your phone may matter as much as how much you use it. A 2024 meta-analysis of 141 studies on active vs passive social media use found that, overall, effects are small, but there is a pattern: passive use (just scrolling and watching) is more consistently associated with worse emotional outcomes, while some forms of active use (commenting, messaging, posting) show small links to greater wellbeing and online social support. (OUP Academic) Other work from Frontiers in Psychology suggests that the emotional impact of passive use depends heavily on how you feel about the content: when it triggers envy, comparison or negativity, mental ill-being goes up; when it’s genuinely positive, the effect can be neutral or even slightly protective for some users. (Frontiers) Reviews also point to upward social comparison, FOMO and rumination as key pathways linking passive browsing to lower wellbeing. (ScienceDirect) Psychotherapist Harshi Sritharan, MSW, RSW works with teens and adults who feel “wiped out” by their feeds and draws a sharp line between passive and active tech use: “Don’t do passive tech use — that doom scrolling, or content just being thrown at you,” she says. “I want people to engage in active tech use. Go and search something up, choose the long-form video you actually want, talk to your friends. Don’t let the app decide everything you see — especially for kids, who are getting content they’re not ready for and didn’t sign up for.” She notes that many of her clients describe feeling “numb, anxious or wired” after long passive sessions, a sign that their nervous system is being pulled around by unpredictable, emotionally loaded content rather than chosen experiences. She also discussed the short term recall related to scrolling: "Some of my clients can't even remember what content they consumed right after scrolling. However, we know that what we pay attention to and what we show our brains has an impact on our thoughts, mindset, feelings and overall internal world." Offline.now founder Eli Singer frames this as a design problem, not a moral failing. The platform’s research shows people already spend about 10 of their 16 waking hours on screens; the realistic goal is to upgrade some of that time, not pretend we can all go offline. His advice: instead of vowing to “get off your phone,” start by swapping just 20 minutes a day from passive to active use; for example, messaging a friend to meet up, learning something specific, or planning an offline activity. “When people tell us they feel overwhelmed by their screen habits, it’s not laziness, it’s a crisis of confidence,” Singer says. “We don’t need perfect digital detoxes. We need small, winnable shifts, like taking one block of passive scrolling and turning it into something you actually chose.” For journalists, the story isn’t simply “screens are bad.” It’s that passive, algorithm-driven scrolling is where comparison, FOMO and emotional overload tend to pile up and that helping people change how they use their devices may be more realistic, and more effective, than focusing on raw minutes alone.

Aston University economists say Prime Minister can reduce UK trade vulnerability with China visit

Greenland episode exposed UK’s lack of effective response to economic coercion from allies Research shows tariff retaliation would have cost the average UK household up to £324 per year Economists say China visit is “portfolio risk management” – diversification reduces vulnerability. The Prime Minister’s visit to China – the first by a British PM since 2018 – is an opportunity to reduce the UK’s vulnerability to economic coercion, according to new research from Aston University. A policy paper from Aston Business School’s Centre for Business Prosperity analyses the January 2026 Greenland tariff episode, when President Trump threatened and then withdrew tariffs on eight European countries. The researchers found that the UK had no good options: retaliation would have made Britain worse off, while absorbing the tariffs left Europe without credible deterrence. Director of the centre for business prosperity, Professor Jun Du, said: “The Greenland episode was a wake-up call. When your principal security ally threatens economic coercion, the old assumptions about who is safe and who is dangerous no longer hold. “The PM’s China visit should be framed as portfolio risk management – building diversified trading relationships that reduce the UK’s exposure to any single partner. Just as investors don’t put all their money in one stock, countries shouldn’t put all their trade into one basket. A UK with multiple strong partnerships is harder to pressure, whether the pressure comes from Washington or Beijing.” The research found that coordinated UK–EU tariff retaliation would have cost British households up to £324 per year – the worst outcome modelled. But the authors argue that Europe has untapped leverage elsewhere: the US runs a €148 billion annual services surplus with the EU, and mutual investment exceeds €5.3 trillion. Associate professor of economics and co-author, Dr Oleksandr Shepotylo, said: “Tariff retaliation fails because it hurts consumers and distorts the economy – the retaliator suffers similarly to the target. But Europe has cards it isn’t playing. Services, investment screening, and regulatory access are pressure points where Europe can respond effectively.” UK exports to China fell by 10.4% in the year to Q2 2025, with goods exports down 23.1% – the sharpest decline among major trading partners. The researchers argue that this closes off the UK’s largest alternative market at precisely the moment US reliability is in question. The paper identifies three priorities for UK policy: Recognise the permanent incentives behind US tariffs. US tariff revenue hit $264 billion in 2025. Trade negotiations alone cannot resolve revenue-driven policy. Build UK–EU coordination on non-tariff instruments. Services, investment, procurement, and regulation offer leverage that tariffs do not. Treat China engagement as portfolio risk management. Concentration in any single market creates vulnerability. Diversification is not about picking sides – it’s about resilience. Professor Du added: “The question for the Prime Minister is whether to use this breathing space to build resilience – or wait for the next Greenland.” To read the policy paper in full, click on this link:

UF works with Gainesville-based Peaceful Paths to educate the public about domestic abuse and cybersecurity

Domestic abuse affects millions of people every year, often in unseen and deeply personal ways, and online threats toward victims can be particularly harmful. To address this reality locally, the University of Florida’s Center for Privacy and Security for Marginalized and Vulnerable Populations, or PRISM, works with Gainesville-based domestic abuse support center Peaceful Paths to help people stay safe in the digital world. Kevin Butler, Ph.D., the director of PRISM and the Florida Institute for Cybersecurity Research at UF, has been researching issues related to security and privacy of technologies that affect survivors of intimate partner violence for years. He and his graduate students connected with Peaceful Paths in 2022, presenting their findings on cybersecurity and demonstrating how their research may help improve online safety for vulnerable populations. They developed a pilot study, a survey and interview protocols that are now helping those in need at the center. “[We aim to] develop principles of design that will allow for a robust technology design that really mitigates harms and improves benefits for all,” Butler said about PRISM. Educating abuse survivors has been a key component of the collaboration between UF and Peaceful Paths. For example, PRISM’s team has conducted research on the effects of stalkerware, also known as spyware, which is a type of software or app designed to be installed secretly on people’s devices to monitor their activities without their consent. Abusers may use this tool to track and harass victims, and stalkerware is regularly linked to domestic violence – a fact that is not widely known. "Even the first presentation [UF] gave enhanced our advocates' knowledge of security pieces, which helps them safety plan with survivors," said Peaceful Paths CEO Crystal Sorrow. “It actually increases the safety of everyone in the community we work with when we talk about red flags, digital dating abuse and healthy relationships.” While PRISM, which is supported by the National Science Foundation, is making an impact on the local community, its overall reach is much broader. PRISM was the first academic partner in the Coalition Against Stalkerware, which includes groups such as the National Network to End Domestic Violence, the Electronic Frontier Foundation, and law enforcement agencies throughout the United States and the world.

We Don’t Realize How Much Time We Spend With AI. Because It’s Hiding in Our Phones

If you ask most people how often they use AI, they’ll say something like: “I tried ChatGPT a couple of times” or “I don’t really use AI.” But look at their phone, and the story is completely different. Digital wellness platform Offline.now has found that we already spend about 10 of our 16 waking hours on screens, roughly 63% of our day. Founder Eli Singer calls AI “the shadow roommate inside those 10 hours”: invisible most of the time, but involved in more of our everyday taps and swipes than we realize. And we now have data to prove it. A recent Talker Research survey of 2,000 U.S. adults, commissioned by Samsung, found that 90% of Americans use AI features on their phones, but only 38% realize it. Common features like weather alerts, call screening, autocorrect, night-mode camera enhancements and auto-brightness are all powered by AI — yet more than half of respondents initially said they don’t use AI at all. Once shown a list of features, 86% admitted they use AI tools daily. (Lifewire) Singer sees this as a classic “confidence gap” problem applied to AI. Beyond the “invisible AI” on our phones, generative AI tools like ChatGPT, Claude and image generators are spreading fast. A nationally representative U.S. survey from Harvard’s Kennedy School and the Real-Time Population Survey found that by August 2024, about 39% of adults aged 18–64 were using generative AI. More than 24% of workers had used it at least once in the previous week, and nearly 1 in 9 used it every single workday. (NBER) Globally, usage is enormous. A World Bank backed analysis of online activity estimated that, as of March 2024, the top 40 generative AI tools attracted nearly 3 billion visits per month from hundreds of millions of users. ChatGPT alone commanded about 82.5% of that traffic. (Open Knowledge Repository) From a mental-health perspective, psychotherapist Harshi Sritharan, MSW, RSW says the issue isn’t just the number of visits, it’s the way AI subtly shapes the texture of our day. “Every autocorrect, every AI-sorted inbox, every ‘magic’ photo fix is a tiny cognitive hand-off,” she explains. “Individually they feel helpful. But taken together, they keep your brain in a constant state of micro-decisions and micro-rewards, which is exhausting, especially if you already struggle with ADHD, anxiety or overwhelm.” She points out that many of her clients only think of “AI time” as the hours they spend in a chatbot window. In reality, AI is involved when: Their phone decides which notifications to surface A map app reroutes them automatically Spam filters silently screen hundreds of emails “By the time they open a dedicated AI app, their nervous system has already been engaging with AI-driven features all day,” Sritharan says. “That’s part of why people end the day feeling tapped out but can’t quite explain why.” Singer worries that this “shadow AI” is quietly eating into the same finite resource Offline.now tracks with screens in general: attention. “We already know 10 hours a day on screens is unsustainable for our focus and our relationships,” he says. “Layer AI on top — systems designed to predict and nudge our behavior — and you’re not just losing time. You’re outsourcing micro-chunks of judgment, memory and choice without even noticing.” So how much time are people spending with AI? Right now, no one has a perfect number and that’s exactly the point. The best data we have suggests: Most smartphone users are already interacting with AI daily, whether they know it or not. (Lifewire) Roughly 4 in 10 U.S. adults now use generative AI, with a growing share using it at work every week or every day. (Harvard Kennedy School) Globally, billions of monthly visits are flowing into AI tools on top of our existing 10-hour screen days. (Open Knowledge Repository) “The future isn’t AI or no AI,” Singer says. “It’s: Can you be conscious about how you use it — instead of letting it hijack your attention and manage your life?” Featured Experts Eli Singer – Founder of Offline.now and author of Offline.now: A Practical Guide to Healthy Digital Balance.

What makes the NFL's biggest game so Super?

Why would someone pay $10,000 for a Super Bowl ticket? Why does the big game serve as a reason for a party – perhaps the only event to do so on a national level? How do teams lock in and play their best while the whole world is watching? University of Delaware experts can deliver answers to those and other questions long before the first chip hits the dip. Amit Kumar, an assistant professor of marketing and expert on happiness, said that part of the reason people derive hedonic benefits from buying tickets to sporting events like the Super Bowl is because of the memories they provide and the conversational value they generate. He pointed to his study on consuming experiences, which found that consumers derive more happiness from purchasing experiences than from buying possessions. Kumar can also talk about the benefits of Super Bowl parties and the psychology behind the social connections that take place at sports-related gatherings. Other UD experts who can comment on the Super Bowl include: • Kyle Emich, professor of management: The inner-working of teams, decision-making and how emotions influence cognitive processing. • John Allgood, instructor of sport management: Fan engagement and the economics of sports. • Nataliya Bredikhina, assistant professor of sport management: Athlete branding and event sponsorships. • Tim Deschriver, associate professor of sport management: Topics related to sports economics, finance and marketing. • Karin Sabernagel, professor of physical therapy: Specializes in lower extremity musculoskeletal injuries, sports medicine and tendon injuries (ankle, knee).
