UF researchers aim to improve nutrition for cancer patients

A new study and first-of-its-kind food pharmacy at UF aim to help patients with cancer access and eat nutritious foods, giving them the best possible shot at a healthy future. As many as a third of cancer patients face food challenges, particularly in rural areas. Good nutrition can improve outcomes during and after treatment. With a grant from the Florida Department of Health, a team of researchers at the University of Florida Health Cancer Center and Sylvester Comprehensive Cancer Center will first assess the community’s nutritional needs. Then they’ll test the usefulness of a food-focused digital tool designed to connect patients to helpful resources. An on-site food pharmacy will help patients not only get the food they need to thrive but also provide tools for lasting change. “We’re taking a community-based approach to holistic cancer care,” said Dejana Braithwaite, Ph.D., associate director for population sciences at the UF Health Cancer Center. “Patients consistently express that nutrition is an important issue for them during cancer treatment. We want to address nutritional needs from treatment through survivorship with a sustainable intervention. ASCENT brings science and community together to make that a reality in Florida.” Braithwaite, a professor and division chief in the UF Department of Surgery, is leading the multi-institution study with Tracy Crane, Ph.D., R.D.N., director of lifestyle medicine, prevention and digital health and co-lead of the Cancer Control Program at Sylvester, part of the University of Miami Health System. Researchers from the UF colleges of Journalism, Medicine, and Public Health and Health Professions and UF/IFAS Extension are participating. The Florida Partnership for Adding Social Context to Address Cancer Survivorship Outcomes study, which the researchers have nicknamed ASCENT, will focus on those affected by the most prevalent cancers in Florida, including breast, lung, colorectal, prostate and blood cancers. “Cancer survivors who follow a healthy dietary pattern have a lower risk of recurrence and death,” said Cora Best, Ph.D., R.D.N., an assistant professor of nutritional sciences in the UF College of Agricultural and Life Sciences and study team member. “Some cancer therapies have long-term or late side effects that increase the risk for chronic conditions, like osteoporosis, which can be alleviated with good nutrition. That means a healthy diet during and after oncologic treatment can enhance lifespan and quality of life.” Researchers will start by conducting interviews with patients, providers and community-based organizations. They want to understand how to best use resources to meet the nutritional needs of those with cancer, such as food security and diet quality. “Community outreach and engagement with various groups is a cornerstone of the study,” said Francis Dalisay, Ph.D., an associate professor in the UF College of Journalism and Communications who helped develop the interview guides. The team will use the information to build a diet intervention with online surveys and patient navigator support, which they will test in a randomized clinical study at UF Health and Sylvester. Patient navigators will connect patients with resources like community programs or specialist referrals. The food pharmacy, located at the UF Clinical and Translational Sciences Metabolic Kitchen, will help cancer patients get healthy, whole nutrient-dense foods like high-protein items, fruits, vegetables and pantry staples. It will also provide workshops, personalized recipes and meal plans. Although the United States is a wealthy nation, food insecurity remains common, including in Florida, Best said. “The ASCENT study pairs evidence-based dietary guidance for cancer survivors with innovative strategies to overcome barriers like food insecurity,” she said. Ultimately, the study aims to empower patients so they can address lifestyle factors in their control, boosting their well-being. “I am hopeful this study will provide patients with appropriate resources to improve their overall nutrition, especially those who are malnourished,” said Paul Crispen, M.D., the Cancer Center’s associate director for clinical research and a study adviser.

New light-based chip boosts power efficiency of AI tasks 100 fold

A team of engineers has developed a new kind of computer chip that uses light instead of electricity to perform one of the most power-intensive parts of artificial intelligence — image recognition and similar pattern-finding tasks. Using light dramatically cuts the power needed to perform these tasks, with efficiency 10 or even 100 times that of current chips performing the same calculations. Using this approach could help rein in the enormous demand for electricity that is straining power grids and enable higher performance AI models and systems. This machine learning task, called “convolution,” is at the heart of how AI systems process pictures, videos and even language. Convolution operations currently require large amounts of computing resources and time. These new chips, though, use lasers and microscopic lenses fabricated onto circuit boards to perform convolutions with far less power and at faster speeds. In tests, the new chip successfully classified handwritten digits with about 98% accuracy, on par with traditional chips “Performing a key machine learning computation at near zero energy is a leap forward for future AI systems,” said study leader Volker J. Sorger, Ph.D., the Rhines Endowed Professor in Semiconductor Photonics at the University of Florida. “This is critical to keep scaling up AI capabilities in years to come.” “This is the first time anyone has put this type of optical computation on a chip and applied it to an AI neural network,” said Hangbo Yang, Ph.D., a research associate professor in Sorger’s group at UF and co-author of the study. Sorger’s team collaborated with researchers at UF’s Florida Semiconductor Institute, the University of California, Los Angeles and George Washington University on study. The team published their findings, which were supported by the Office of Naval Research, Sept. 8 in the journal Advanced Photonics The prototype chip uses two sets of miniature Fresnel lenses using standard manufacturing processes. These two-dimensional versions of the same lenses found in lighthouses are just a fraction of the width of a human hair. Machine learning data, such as from an image or other pattern-recognition tasks, are converted into laser light on-chip and passed through the lenses. The results are then converted back into a digital signal to complete the AI task. This lens-based convolution system is not only more computationally efficient, but it also reduces the computing time. Using light instead of electricity has other benefits, too. Sorger’s group designed a chip that could use different colored lasers to process multiple data streams in parallel. “We can have multiple wavelengths, or colors, of light passing through the lens at the same time,” Yang said. “That’s a key advantage of photonics.” Chip manufacturers, such as industry leader NVIDIA, already incorporate optical elements into other parts of their AI systems, which could make the addition of convolution lenses more seamless. “In the near future, chip-based optics will become a key part of every AI chip we use daily,” said Sorger, who is also deputy director for strategic initiatives at the Florida Semiconductor Institute. “And optical AI computing is next.”

Villanova Tax Experts Break Down Legislative Changes, Best Practices Before Filing Deadline

It's time to collect your W-2s, 1098s and 1099s: On April 15, Americans are required to submit their annual tax returns—recapping earnings, income and life events from the past calendar year. Yet, as filers prepare their records and statements for 2025, they should anticipate some substantial departures from the 2024 season. According to Stephen Olsen, JD, faculty director of the Graduate Tax Program at Villanova University Charles Widger School of Law, and Luke Watson, PhD, associate professor of Accounting in the Villanova School of Business, one of the most significant drivers of change is the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025. A sweeping piece of legislation, OBBBA has instituted a number of new tax rules and regulations, including a deduction of $6,000 for taxpayers over 65 years of age, a deduction for certain overtime payments up to $12,500, a deduction for certain tips up to $25,000 and an increase in the state and local tax (SALT) deduction cap from $10,000 to $40,000. Given these policies, most taxpayers should expect a modest decrease in taxes owed this season, and refunds on average should trend higher than in 2025—something borne out by early data from the U.S. Department of Treasury. Of course, the full extent and range of the windfalls have yet to be discovered. "It is unclear if the average refund will be as high as estimated by the administration or what the actual distribution of those tax benefits will be," says Professor Olsen. "Not every taxpayer will receive a significant benefit, and there are so many factors that could cause someone's tax bill to increase, including increased taxable income, the loss of other deductions, changes in filing status and claimed dependents." "There are also many restrictions and phaseouts that changed with OBBBA," adds Dr. Watson. "For example, many seniors and tipped workers paid little to no income tax even under prior law, so they would not necessarily see much benefit with the new legislation." As Dr. Watson's remarks reflect, the question of who exactly qualifies for and benefits from OBBBA's provisions has preoccupied the general public for quite some time. In particular, the deduction-related measure tied to tips, or the "no tax on tips" policy, has sparked curiosity. "Like many things in the Internal Revenue Code, 'no tax on tips' sounds simple, but the actual law is a bit more nuanced," says Professor Olsen. "Only workers who are in an occupation that 'customarily and regularly' receives tips qualify for this deduction. This includes lots of people in transportation, personal services and the food, beverage and hospitality industries—even some in entertainment. "Certain professions, including those in healthcare, law, accounting, financial services and consulting, will likely be prohibited from taking the deduction… Importantly, qualifying workers will need to be able to prove their tip income to take the deduction." "It is also worth noting that, due to the generally lower-wage nature of tipped jobs and the historical underreporting of tips on returns, many taxpayers earning tips paid little to no tax on tips in prior years," says Dr. Watson. "So, they would not experience much of a change under OBBBA." Navigating new provisions like this one, during a process and time already known for provoking anxiety, can be a daunting prospect for many taxpayers. What's more, administrative adjustments at the Internal Revenue Service (IRS) could potentially exacerbate levels of stress. "IRS staffing remains lower than in past years, which could impact customer service and processing of returns," says Professor Olsen. "In addition, the current administration has elected to eliminate the IRS Direct File tool for income taxes that was available last year. Taxpayers who used the tool last year will need to find other options for the preparation of their income tax returns." For those concerned about filing and worried about abiding by the new rules and regulations, Professor Olsen and Dr. Watson highlight the importance of remaining organized, maintaining a game plan and, if necessary, seeking assistance. "First, taxpayers should be proactive," says Professor Olsen. "Start gathering information as soon as possible and start the process of preparing your returns as early as possible. That will provide you with more time to troubleshoot issues or find other information you may not have initially gathered." "Free resources are also available for taxpayers," says Dr. Watson. "There is a federal volunteer-run program called Volunteer Income Tax Assistance (VITA) that operates throughout communities to prepare tax returns for free, and many of the big tax prep companies do offer a free version of their software, despite trying very hard to sell a paid version. "That said, the best advice is to keep thorough tax and financial records throughout the year. Then, seek help—such as through VITA—when you need it. The better your records, the easier it will be for VITA or others to assist you."

What the Meta/YouTube Verdict Still Misses About Youth Social Media Harm

The verdict against Meta and YouTube has reignited debate over addictive design and youth social media harm. But according to Harshi Sritharan, clinician and digital dependency expert with Offline.now, one key issue is still being overlooked: digital emotional regulation. Sritharan works with young people and families dealing with the real-life fallout of harmful platform design, including compulsive scrolling, sleep disruption, body-image distress, emotional dysregulation, and conflict at home. “The goal isn’t to remove technology from their lives entirely,” says Sritharan. “It’s to help young people and their families build healthier relationships with it.” She can speak to why regulating platform design matters, why digital resilience and online emotional regulation should be treated as core life skills, and why simply restricting access without healthier alternatives can push vulnerable youth into harder-to-monitor spaces. As news coverage focuses on liability and platform accountability, Sritharan offers a frontline clinical perspective on what these harms actually look like inside homes - and what young people, parents, schools, and policymakers may still be missing. ABOUT THE EXPERT Harshi Sritharan is a clinician and digital dependency expert with Offline.now, a digital wellness platform connecting individuals and families with therapists, coaches, and social workers who specialize in healthier relationships with technology.

Study: Many pregnant women uncertain of marijuana risks even as use increases

Many pregnant women are unsure if it’s safe to use marijuana or products containing cannabidiol, an active compound in marijuana, even as they increasingly turn to them to combat morning sickness, anxiety or insomnia, a recent University of Florida Health study shows. The American College of Obstetricians and Gynecologists advises against the use of marijuana and cannabidiol, or CBD, during pregnancy. Marijuana use has been associated in some studies with adverse fetal neurodevelopmental outcomes. Evidence of cannabidiol safety is sparse in human studies, but researchers remain concerned that it might nonetheless pose a danger. CBD is not intoxicating. The UF Health researchers said their study shows a need for the medical community to better educate women about the potential hazards to the fetus from using marijuana, also called cannabis. One worry is that some people believe the spreading legalization of marijuana or CBD around the nation equates to the government giving its stamp of approval that the products are safe, researchers said. Medical marijuana is legal in Florida, although its recreational use is not. “If a medication is legal, we assume that maybe it’s safe, although other things like tobacco and alcohol are also legal and we know that those can be harmful to pregnancies,” said Kay Roussos-Ross, M.D., the study’s senior author and a professor in the UF College of Medicine’s Department of Obstetrics and Gynecology. “We see a good deal of data out there that shows that there is increased risk of psychiatric and behavioral issues related to marijuana use in pregnancy, but we need more,” she added. “We need more so that we can be correct in our assessments and our educational efforts to women of reproductive age who are using marijuana.” It’s difficult to quantify the rise of marijuana and CBD use during pregnancy, with most estimates showing an increase predating COVID-19. A 2021 federal survey reported 7.2% of pregnant women used marijuana. The UF Health study noted that emerging evidence from obstetrics care shows more pregnant women are trying the products, perhaps because of increased legalization. The study, published in Medical Cannabis and Cannabinoids, surveyed 261 women and used focus groups to explore participants’ perceptions of the products. The women were either pregnant, breastfeeding or caring for a child 5 years old or younger, and reported use of marijuana or CBD products, such as vapes, smoking, tincture oils or ointments. “There seems to be a disconnect,” said Amie Goodin, Ph.D., an assistant professor in the UF College of Pharmacy’s Department of Pharmaceutical Outcomes and Policy and the study’s lead author. “About one in six pregnant women are telling us, ‘Yes, I have used marijuana or a CBD product while I’m pregnant.’ But half are saying, ‘I don’t know what the risks are.’” About 40% of the pregnant women surveyed said they were unsure how risky it was to use marijuana once or twice a week during pregnancy, compared with 34.5% of women who were not pregnant when surveyed for the study but who had children. Asked the same question about CBD, more than 52% of pregnant women were unsure of the risk, compared with 41.8% for mothers who weren’t pregnant when surveyed. About 36% of pregnant women reported using marijuana, compared with 65% of mothers not currently pregnant, perhaps reflecting at least some increased caution among those in the former group. CBD use was 19.9% for pregnant women and 38.2% for women who were not pregnant. “Some women did mention that the legalization of marijuana has made marijuana more socially acceptable,” said study co-author Deepthi Varma, Ph.D., an assistant professor in the College of Public Health and Health Professions’ Department of Epidemiology. The researchers said they were especially concerned that women were even less sure of the safety of CBD use because it is widely available and often seen as harmless. “You might notice that it’s even something that you can buy at a gas station or a grocery store,” Goodin said. “CBD in a purified form has actually got an FDA approval to treat certain types of pediatric epilepsy on its own … but pharmaceutical-grade CBD is not quite the same thing as you would expect to get if you were purchasing CBD oil at a smoke shop or a gas station.”

Target Can’t Seem to Escape the Crosshairs

The on-again-off-again nationwide boycott of Target has the retailer’s new chief executive, Michael Fiddelke, officer facing relentless pressure from activists on both sides of the issue. David Primo, a professor of political science and business administration at the University of Rochester, says Fiddelke can’t seem to move Target from the crosshairs despite slashing prices on thousands of products and investing in stores, workers, and technology. “Target remains a battleground for activists on the left and the right, and its new CEO hasn’t yet figured out how to extricate the company from this role,” Primo recently told USA Today. “Fiddelke already faces a huge challenge in turning around a company with significant operational issues. This certainly doesn’t help matters.” Target has reported 13 straight quarters of sluggish sales. Company officials have admitted that shopper anger has contributed. Activists in Minneapolis, where Target is based, organized a nationwide boycott last year over the company’s rollback of diversity, equity, and inclusion policies. From church pulpits to community gatherings, the policy about-face was widely viewed as a betrayal of Black Americans who had propped up the retail giant’s bottom line. Primo studies corporate political strategies, among other areas, and regularly shares his insights with business journalists and political reporters. His essays have appeared in The New York Times and The Wall Street Journal, and he’s been interviewed by many radio and television outlets, including Bloomberg and National Public Radio.

Your Retirement Reset: My New Book will Be in Stores on Sept. 8th

This one has been a long time coming. My new book, Your Retirement Reset: How to Convert Home Equity into Financial Security, published by ECW Press, finally has a publication date. Why I Wrote This Book I have spent decades watching far too many older Canadians carry unnecessary financial stress into what should be a more secure and dignified stage of life.  Throughout my career as a mortgage broker, business owner, and later as an executive at HomeEquity Bank, I saw the same painful pattern again and again: people who had worked hard, paid down their homes, built real equity, and still felt trapped. Many were living with fear, cutting back on basic pleasures, worrying about every bill, and feeling ashamed that they had not “saved enough.” Meanwhile, a major asset was sitting right beneath their feet. What struck me most was this: younger homeowners often see home equity as a financial tool, but many retirees do not. For many older Canadians, the idea of borrowing against their home feels frightening, even when it could improve their quality of life and help them stay independent. This resistance is not just about math. It is emotional. It is psychological. And it is deeply tied to identity, security, family, and fear. The Retirement Problem We Are Not Talking About Honestly Enough The old retirement script is failing too many people. We are living longer. The cost of living keeps rising. Private sector pensions have largely disappeared. Healthcare and long-term care costs are real concerns. And many people reaching retirement are discovering, far too late, that the traditional advice to simply save, downsize, and make do does not reflect today’s reality. At the same time, most older Canadians want to age in place. They want to remain in the homes and communities they know and love. They do not want to be pushed into selling, renting, or moving in with family unless they truly choose that path. Yet many are gripped by what I call FORO — Fear of Running Out. That fear shapes countless decisions and robs people of peace of mind. It’s actually rooted in neuroscience and the way we’re wired to behave as we do. I’ve posted about this here in my newsletter and Substack a lot. Because it’s important. This is not a fringe issue. It is a national issue. And it deserves a more honest conversation. Why This Book Matters for Canadians 55+ There is a critical gap in this country when it comes to retirement literacy. Many Canadians over 55 have substantial value tied up in their homes, yet traditional retirement advice often does not seriously incorporate home equity into the conversation. At the same time, the information people do find is often fragmented, biased, overly technical, or scattered across lenders, planners, brokers, lawyers, accountants, media stories, and well-meaning family members. That leaves people vulnerable. They may rely on outdated assumptions. They may wait too long to explore options. They may make decisions out of fear rather than clarity. And because older adults usually do not have decades to recover from a financial mistake, the stakes are high. I want to be direct about this: one wrong decision later in life can be extremely hard to reverse. Seniors need unbiased, transparent information they can actually trust. I wanted to create a resource that is practical, plainspoken, and empowering. Not a sales pitch. Not a jargon-filled textbook. Not a one-size-fits-all solution. What I Hope This Book Will Accomplish I hope “Your Retirement Reset” helps Canadians 55+ do a number of things. First, I hope it helps people understand their options more clearly. Too many retirees only hear about a narrow set of choices. I want readers to see the full landscape and understand how different strategies work, including the pros, cons, and trade-offs. Second, I hope it helps people replace fear with confidence. Retirement should not be defined entirely by scarcity thinking. When people understand how to use all of their assets strategically, including home equity, they can make decisions from a position of strength rather than panic. Third, I hope it helps families have better conversations. One of the great hidden challenges in retirement planning is communication. Adult children often mean well, but they may not understand the emotional reality of aging, independence, or financial vulnerability. These conversations matter, and they are often avoided until a crisis forces them. This book is meant to encourage healthier, earlier, and more respectful dialogue. Fourth, I hope it helps more older Canadians protect their dignity and independence. To me, this is the heart of the matter. As I work through my current MBA studies, my life today is filled with spreadsheets. But retirement shouldn’t be. It is about autonomy, confidence, lifestyle, peace of mind, and the ability to live on your own terms for as long as possible. The Information Gap Nobody Is Filling One reason I felt so compelled to write this book is that the resources simply are not where they need to be. There is no shortage of opinions in the marketplace. But there is a shortage of clear, balanced, accessible education specifically designed for older Canadians trying to navigate retirement in the world as it actually exists now. Many books in this category are dated, narrowly focused, or too technical for many of the people I speak with. And it’s to be expected that much of the consumer-facing content around financial products like reverse mortgages comes from lenders themselves. Many seniors are left trying to piece together a life-changing financial strategy from disconnected advice and Google searches. That is the gap I am trying to fill. Canadians need impartial, balanced information they can trust — especially around home equity strategies and retirement financing. I believe Canadians deserve better than that. They deserve a resource that speaks to them in plain language, respects their intelligence, acknowledges the emotional complexity of these decisions, and gives them practical tools to move forward. We Need a More Modern Retirement Roadmap This book is built around a simple idea: retirement planning cannot just be about accumulating savings. It also has to be about learning how to use those resources wisely. That includes understanding how to: • create income • manage spending • shelter income from unnecessary tax pressure • protect savings from fraud and bad decisions • evaluate whether home equity should play a role in your retirement strategy These are the pillars I keep coming back to. They reflect what I believe Canadians in this stage of life truly need.  I want readers to come away not just informed, but steadier. More capable. More hopeful. This Is Personal for Me I am part of this demographic myself. I understand the questions, the transitions, the uncertainty, and the pressure. I also know from lived experience that retirement is not simply a financial event. It is a life event. It affects your confidence, your relationships, your routines, your health, and your sense of who you are. That combination — professional experience and personal experience — is exactly what I bring to every page. That is why I have approached this book not simply as a finance book, but as a practical guide for real people facing real decisions. My hope is simple: that this book helps more Canadians 55+ move into the next chapter of life with greater knowledge, less fear, and a stronger sense of possibility. Because retirement should not just be about getting by. It should be about living with confidence, dignity, and choice.
