As interest in cryptocurrencies move from the fringes to mainstream conversation and public policy debate, Derek Mohr, clinical associate professor of finance at the Simon Business School at the University of Rochester, offers a clear-eyed voice on the subject. Mohr specializes in financial innovation and digital assets, and he’s been in demand with reporters looking to understand the economics behind everything from “Bitcoin-powered” home heaters to gas stations offering discounts for crypto purchases. His message? Not everything that markets itself as a breakthrough actually adds up. For instance, some companies have pitched devices that promise to heat a home using excess energy generated from bitcoin mining. Mohr recently told CNBC the idea might sound clever, but that its practicality collapses under basic financial and engineering realities. “The bitcoin heat devices I have seen appear to be simple space heaters that use your own electricity to heat the room . . . which is not an efficient way to heat a house,” Mohr said. “Yes, bitcoin mining generates a lot of heat, but the only way to get that to your house is to use your own electricity.” Bitcoin mining, he explained, has become so specialized that home computers have virtually zero chance of earning a mining reward. Industrial mining farms operate on custom-built chips far more powerful than any consumer device. In other words, consumers who think they’re heating their homes and earning crypto are, in reality, just paying for electricity and getting no real mining benefit. A pragmatic voice in a volatile space Mohr’s research and commentary help explain not just what is happening in the crypto world, but why it matters for consumers, businesses, and regulators. Whether evaluating the economics of mining or the viability of crypto payments, he brings a steady, analytical perspective to a domain dominated by hype and fast-moving news cycles. For journalists covering cryptocurrency, fintech, and the future of financial transactions, Mohr is available for interviews on digital payments, bitcoin mining economics, crypto regulation, and emerging trends in financial technologies.

Christmas Magic on Screen: A Curated List of Must-Watch Holiday Classics
Christmas movies and TV specials hold a special place in the hearts of many, offering a blend of nostalgia, joy and fun that captures the magic of the holiday season, creating a sense of togetherness, drawing families and friends around the glow of the television. James Kendrick, Ph.D., a film historian and professor of film and digital media at Baylor University, has curated a list of his Top 5 Christmas movies and specials, sharing the history of how they became holiday classics sure to fill you with holiday cheer. View his profile 1. It’s a Wonderful Life Frank Capra’s classic is the perennial Christmas movie, which is only fitting given that it began with writer Philip Van Doren Stern penning a short story called “The Greatest Gift” and printing it on 200 holiday cards that he sent to friends and family. Although initially a box office dud, it later fell into the public domain and was used by PBS stations during the 1970s as December counterprogramming, turning it into the holiday classic it always deserved to be. Along with stockings hung by the fireplace, decorated trees and blinking lights on the house, the viewing of “It’s a Wonderful Life” has become indelibly interwoven into contemporary Christmas tradition. Capra weaves a rich tapestry of American life filling the screen, including memorable details and wonderful performances from James Stewart in his first role after returning from duty in World War II, and Donna Reed, then a largely unknown contract player. It is a truly classic, timeless film, one of the few that quite simply never grows old. 2. Die Hard It is a long-settled matter that Die Hard is not just a Christmas movie, but one of the very best. Christmas movies, after all, know no genre, so there is no reason why a violent action film can’t fit the bill for the holidays. The decision to set John McTiernan’s wry action extravaganza against a Christmas-season backdrop only adds to the film’s myriad pleasures, as it makes Bruce Willis’s one-man mission to eradicate a crack team of terrorist-robbers all the more imperative after they take a Los Angeles high-rise hostage along with a party of business executives that include his estranged wife. “The fact that the soundtrack includes as many jingle bells as gunshots (well, maybe not quite as many, but still more than a few) only adds to the seasonal feels,” Kendrick said. 3. A Christmas Story Somewhere inside we are all young, round-faced Ralphie, pining away for our own “official Red Ryder carbine action, 200-shot Range model air rifle with a compass in the stock and this thing which tells time.” The film’s stroke of brilliance in how it ladles halcyon American nostalgia – so many images from the film could have been painted by Norman Rockwell – with a biting sense of cold, but often hilarious, reality. Humorist Jean Shepherd, parts of whose 1966 semi-autobiographical short story collection, In God We Trust: All Others Pay Cash, provided the film’s source material, narrates the film with a mix of humor and irony, making each scene work as both an evocation of a specific time and place in American history and a blank slate onto which we can project our own Christmas memories and dreams. The fact that the genuine, child wonderment of waking up on Christmas morning co-exists so easily with sneering bullies, creatively cursing fathers, draconian teachers, tongues frozen to light poles, inappropriate major awards and the always braying Bumpass hounds is testament to the film’s breadth and depth. 4. A Charlie Brown Christmas The first and best of the Peanuts TV specials (sorry, Great Pumpkin), A Charlie Brown Christmas premiered in 1965 and has been in our hearts ever since. While technically not a feature film, it captures in its brisk 22 minutes both the truth of the Christmas spirit and the attendant interpersonal difficulties of the holiday season. The fact that it does so with such good humor and poignancy means that no Christmas viewing list is complete without it. Charlie Brown’s oft-frustrated attempts to fit in and find meaning in the season amid all the crass commercialism is one of pop culture’s greatest evocations of existential struggle, but all the low points are balanced perfectly with Linus’s simple, illuminating recitation of the annunciation to the shepherds from the Gospel of Luke, which remains remarkably powerful in its unadorned directness. From the mouth of babes, indeed. 5. National Lampoon’s Christmas Vacation This is the movie for everyone who has ever tried their absolute hardest to live up to the hype of the Christmas season, only to end in abject failure. Maybe we haven’t all crashed and burned as badly as poor Clark Griswold does here, but we can all relate to how the idea of a “good ol’ fashioned family Christmas” doesn’t always comport with the realities of family, especially when your family includes the inveterate Cousin Eddie, who thinks nothing of emptying his rusting hulk of an RV’s chemical toilet into a storm drain first thing in the morning while wearing a shorty robe and smoking a cigar. John Hughes’s screenplay is a veritable compendium of modern America’s expectations for the season and how they can all go terribly, horribly wrong, which is enough to make anyone feel better about their own Christmas turkey coming out too dry or inability to find which lightbulb is causing the whole strand to go dark.
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.
Stress-Free Holiday Gatherings Made Simple
Holiday gatherings often bring a mix of joy and challenges, especially when navigating complex family dynamics. Anticipating potential hurdles, such as sensitive topics or interpersonal tensions, can help family members approach these events with confidence and clarity. Baylor University communication expert Allison M. Alford, Ph.D., researches adult daughtering, invisible labor and family relationships and emphasizes the importance of preparation to ensure a more relaxed and enjoyable experience for everyone over the holidays. She shares five practical tips to help families navigate the holidays with ease: Dr. Allison Alford’s Five Family Tips for a Stress-free Holiday 1.Work out known hurdles before you arrive to the holiday event. Family dynamics often have predictable friction points – whether it’s a difference in political views, sibling rivalries or unresolved conflicts. Identify these hurdles in advance and decide how to approach them. “For instance, if you anticipate a certain topic will come up, plan a calm response or rehearse setting a boundary,” Alford said. “If you’re traveling with a partner or children, discuss how you’ll handle challenging moments as a team. The goal is to minimize surprises and feel equipped to manage potential stressors.” 2.Come prepared with a list of topics you’re ready and willing to talk about (and off-limits subjects, too!). Having a mental (or physical!) list of neutral or positive conversation topics can keep the mood light and engaging, Alford said. “Think about shared hobbies, family memories or recent accomplishments,” she said. “At the same time, identify subjects that are off-limits for you – like contentious debates or sensitive personal matters – and practice polite ways to redirect or deflect those conversations. For example, you could say, ‘I’d rather not get into that today. Tell me about your new garden!’ Preparation is key to feeling in control of the dialogue.” 3.Set a mantra for your intention. Repeat often. Alford suggests anchoring yourself with a phrase or saying that aligns with your values and goals for the event. For example, “I will stay calm and kind,” or “I am here to connect, not to control.” Repeat this mantra to yourself whenever you feel stress creeping in. “It acts as a mental reset and helps you respond intentionally rather than react impulsively. Over time, this practice can shift your mindset and create a buffer against family tension,” Alford said. View her profile 4.Take breaks when you feel things going off the rails. Recognizing when you’re overwhelmed is a vital skill. If emotions are running high, excuse yourself for a breather. A short walk, stepping outside for fresh air, or even taking an extended “bathroom break” can provide the time you need to decompress and regroup. “Use this break to practice deep breathing, text a supportive friend or simply enjoy a few moments of solitude. Returning with a clearer head can prevent escalation and help you maintain your composure,” Alford said. 5.Stand up for your needs. Don’t abandon yourself! While family gatherings often involve compromise, Alford said it’s important not to sacrifice your emotional well-being. If a situation feels uncomfortable or hurtful, express your needs calmly but firmly, she said. For example, “I feel uncomfortable when this is discussed. Let’s talk about something else.” “Prioritize your mental health and remember that it’s okay to say no, step away or leave early if necessary. Standing up for yourself sends a clear message that your feelings matter and reinforces healthy boundaries,” Alford said. By addressing known hurdles in advance, curating conversation topics, setting personal intentions and taking mindful breaks when needed, Alford said family members can create a buffer against tension and foster meaningful connections. “At the same time, standing up for your needs and setting boundaries helps preserve your emotional well-being,” she said. “With these strategies, you’ll be better equipped to approach holiday events with confidence and calm.”
Navigating Grief During the Holiday Season
The holiday season is a time of joy, togetherness and celebration, but for many – especially those who are grieving the death of a loved one or a deep loss – it can bring a complex mix of emotions, ranging from sadness and sorrow to gratitude and joy. Baylor University professors Candi Cann, Ph.D., a death scholar and associate professor of religion in the Honors College, and Jo-Ann Tsang, Ph.D., a leading gratitude researcher and associate professor of psychology, offer four strategies for people experiencing difficult emotions and grief during the holidays. Embrace the spectrum of emotions Both Tsang and Cann say the key to maintaining balance and authenticity – even while deep in grief – is understanding and accepting where you are emotionally. “It’s possible and normal to feel different emotions at one time,” Tsang said. “You can feel happiness during the holidays, but also sad that you miss someone who you wish were present. Being grateful does not rule out feeling other emotions; we can cultivate gratitude, but that does not necessitate running away from other emotions.” Cann pointed out that grief can be complicated if the death or loss is from a difficult relationship. “It is okay to feel relief in addition to grief and it is important to validate all of your feelings – it’s a complicated grief because it was a complicated relationship,” Cann said. The importance of self-care Self-care is vital during this time, Cann said. She encourages grieving people to stay active, eat healthy, go outside to be in nature and get enough sleep. “It’s totally normal to need more sleep when you're depressed and grieving. You just have to be gracious with yourself about that,” Cann said. Allowing ourselves to feel emotions like stress, sadness or grief gives us insight into what we value and “can motivate us to take some time for self-care,” Tsang said. Acknowledging that we are stressed might lead us to reach out to others for help with tasks that overwhelm us or to let go of things to reduce stress. In addition to taking care of your physical health, staying engaged in your community or church and being in community with others is beneficial for mental health, Cann said. But at the same time, be honest with yourself about what you want to do and only accept invitations or participate in activities that you feel you can handle, she added. The place of gratitude Tsang suggests approaching challenging emotions with gratitude as it “might also provide context and perspective for our loss and potentially transform our negative emotions.” “As an example, I might feel frustrated that I am sad but then feel grateful that I have good family and neighbors to check on me and coworkers to help me finish the tasks that I can’t do while I’m down,” Tsang said. “This gratitude might help reduce my frustration by helping me see the support that is present in my life, on which I had not previously reflected.” At the same time, she reiterated that, in addition to cultivating gratitude, it’s important for people to permit themselves to experience negative emotions such as grief and sadness in response to life circumstances. “It’s okay if it’s hard to experience gratitude. God meets us where we are,” Tsang said. Evaluate traditions and embrace memories Cann suggests evaluating family traditions, choosing those that are most important to continue and starting new traditions that include their loved one. “A lot of people feel like when that person is gone, the love is gone too, but the love is still there,” Cann said. “You wouldn't feel the grief or the big hole that you now have if you didn't have all of this love in the first place.” She suggests embracing their loved one’s presence by including a place at the table for Christmas dinner, making their favorite recipe or finding other ways to continue the bonds. By doing these things, “you're including them in your conversation, and you're making space for that person, both literally and symbolically,” Cann said. Supporting someone who is grieving Being supportive of someone grieving requires patience and vulnerability. “Engage with the person and ask how you can best support them, and let them know that you are thinking about them during this time,” Cann said. Sometimes, friends or family members don’t want to bring up death during the holidays because they don't want to make people sad at a joyful time. “But the point is, they already are sad, so bringing it up allows them to express it” and feel accepted in their pain, Cann said. It also is important to remember that not all grief is related to death. There are many types of loss that people experience such as divorce or disease. The Baylor researchers note that we can’t decide or predict what defines another person's grief, but we can offer love and support. Approaching the holidays when experiencing grief over a death or a deep loss may be painful at first, but using these strategies can help us face the future by celebrating with gratitude what we had in the past. Ultimately, the holidays are a time for reflection, connection and self-compassion. Allow yourself to feel your emotions fully – whether joyful, challenging or a mix of both – and use them as guides for meaningful action. Looking to know more or arrange an interview?

Violence alters human genomes for generations, researchers discover
In February of 1982, the Syrian government besieged the city of Hama, killing tens of thousands of its own citizens in sectarian violence. Four decades later, rebels used the memory of the massacre to help inspire the toppling of the Assad family that had overseen the operation. But there is another lasting effect of the attack, hidden deep in the genes of Syrian families. The grandchildren of women who were pregnant during the siege — grandchildren who never experienced such violence themselves — nonetheless bear marks of it in their genomes. Passed down through their mothers, this genetic imprint offers the first human evidence of a phenomenon previously documented only in animal models. The genetic transmission of stress across multiple generations. “The idea that trauma and violence can have repercussions into future generations should help people be more empathetic, help policymakers pay more attention to the problem of violence,” said Connie Mulligan, Ph.D., a professor of Anthropology and the Genetics Institute at the University of Florida and co-senior author of the new study. “It could even help explain some of the seemingly unbreakable intergenerational cycles of abuse and poverty and trauma that we see around the world, including in the U.S.” While our genes are not changed by life experiences, they can be tuned through a system known as epigenetics. In response to stress or other events, our cells can add small chemical flags to genes that may quiet them down or alter their behavior. These changes may help us adapt to stressful environments, although the effects aren’t well understood. It is these tell-tale chemical flags that Mulligan and her team were looking for in the genes of Syrian families. While lab experiments have shown that animals can pass along epigenetic signatures of stress to future generations, proving the same in people has been nearly impossible. “Resilience and perseverance is quite possibly a uniquely human trait.” —Connie Mulligan Mulligan worked with Rana Dajani, Ph.D., a molecular biologist at Hashemite University in Jordan and co-senior author, as well as anthropologist Catherine Panter-Brick, Ph.D., of Yale University, to conduct the unique study. Dajani envisioned the research project; because of her intimate knowledge of the Syrian population and its tragic history, she designed the study to cover three generations of Syrian refugees to Jordan. Some families had lived through the Hama attack before fleeing to Jordan. Other families avoided Hama, but lived through the recent civil war against the Assad regime. The team collected samples from grandmothers and mothers who were pregnant during the two conflicts, as well as from their children. This study design meant there were grandmothers, mothers and children who had each experienced violence at different stages of development. A third group of families had immigrated to Jordan before 1980, avoiding the decades of violence in Syria. These early immigrants served as a crucial control to compare to the families who had experienced the stress of civil war. Study coauthor Dima Hamadmad, a Syrian researcher and the daughter of refugees, led the search for families that met the study criteria and collected cheek swabs from 138 people across 48 families. "The participants took part in the research out of love for their children and concern for future generations,” she said. “But more than that, they wanted their stories of trauma to be heard and acknowledged.” Back in Florida, Mulligan’s lab scanned the DNA for epigenetic modifications and looked for any relationship with the families’ experience of violence. In the grandchildren of Hama survivors, the researchers discovered 14 areas in the genome that had been modified in response to the violence their grandmothers experienced. These 14 modifications demonstrate that stress-induced epigenetic changes may indeed appear in future generations in humans, just as they can in animals. The study also uncovered 21 epigenetic sites in the genomes of people who had directly experienced violence in Syria. In a third finding, the researchers reported that people exposed to violence while in their mothers’ wombs showed evidence of accelerated epigenetic aging, a type of biological aging that may be associated with susceptibility to age-related diseases. Most of these epigenetic changes showed the same pattern after exposure to violence, suggesting a kind of common epigenetic response to stress – one that can not only affect people directly exposed to stress, but also future generations. “We think our work is relevant to many forms of violence, not just refugees. Domestic violence, sexual violence, gun violence: all the different kinds of violence we have in the U.S,” said Mulligan. “We should study the effects of violence. We should take it more seriously.” It’s not clear what, if any, effect these epigenetic changes have in the lives of people carrying them inside their genomes. But some studies have found a link between stress-induced epigenetic changes and diseases like diabetes. One famous study of Dutch survivors of famine during World War II suggested that their offspring carried epigenetic changes that increased their odds of being overweight later in life. While many of these modifications likely have no effect, It’s possible that some have functional effects that can affect our health, Mulligan said. The researchers published their findings, which were supported by the National Science Foundation, Feb. 27 in the journal Scientific Reports. While carefully searching for evidence of the lasting effects of war and trauma stamped into our genomes, Mulligan and her collaborators were also struck by the perseverance of the families they worked with. Their story was much bigger than merely surviving war, Mulligan said. “In the midst of all this violence we can still celebrate their extraordinary resilience. They have persevered,” Mulligan said. “That resilience and perseverance is quite possibly a uniquely human trait.”
The School of Science at Rensselaer Polytechnic Institute (RPI) has launched a new minor in quantum computing, positioning students at the forefront of one of the most rapidly developing fields in technology. The minor leverages RPI's unique status as the first university in the world to house an IBM Quantum System One on campus, providing students with unprecedented access to utility-scale quantum computing technology. The minor, which is now available to all currently enrolled students, requires four courses drawn from physics, computer science, mathematics, and engineering. The curriculum provides both theoretical foundations and practical exposure to quantum hardware and software, and gives students a leg up in a field rapidly approaching quantum advantage — the point at which quantum systems outperform classical computing approaches on meaningful tasks. "The quantum computing minor will augment the training of RPI students with insight into an emerging technology that will reshape industries from pharmaceuticals to artificial intelligence," said Steven Tait, Ph.D., Dean of the School of Science. "With direct access to the IBM Quantum System One, our students will gain hands-on experience with cutting-edge tools that are not yet widely available. This minor equips them with the interdisciplinary foundation needed to understand and contribute to quantum-enabled innovation." The minor arrives at a pivotal moment in quantum computing's evolution. IBM's demonstration of quantum utility in 2023 marked the beginning of an era in which quantum systems serve as scientific tools to explore complex problems in chemistry, physics, and materials science — areas where quantum advantage offers transformative potential. Hannah Xiuying Fried, graduating this December, is one of the first students to declare the minor. “I'm not a physics or computer science major, so it allows me an accredited way to prove a relevant background to future employers,” she said. “It prepares me for graduate school where I plan to continue pursuing quantum hardware research.” Currently enrolled students may declare the minor now and pursue it alongside their established degree programs. Interested students should contact Chad Christensen at sciencehub@rpi.edu.
Trim the Clutter, Keep the Cheer
The holiday season brings warmth, joy and a touch of magic into our homes, but it also can bring excess clutter, waste and energy consumption, making it hard to feel festive. However, there are simple and creative ways to decorate sustainably without sacrificing the festive spirit. Baylor University human sciences and design professor Elise King, M.I.D., M.A., an expert in interior design and built environments, says embracing sustainable decorations, changing to energy-efficient lights, eliminating clutter and reducing waste can help maintain a tidy, eco-friendly home – and create a holiday atmosphere that resonates with joy and meaning. “The holidays can often feel busy and stressful, so it’s helpful to focus on traditions and decorations that bring joy and add meaning to the season,” King said. By taking simple steps to reuse materials, reduce energy consumption and focus on what matters most, families can celebrate the season with both heart and mindfulness, King said. Decorating sustainably One of the easiest ways to approach sustainable decorating is by reusing or repurposing materials you already have or finding decorations at resale shops. "Upcycling items from thrift stores or turning last year’s Christmas cards into garlands are simple and creative ideas," King said. “Beyond thriftiness, these practices add a personal and nostalgic touch to decorations.” King also said that it is important to consider the lifecycle of a product, beyond just being recyclable. "Also consider elements such as durability/longevity, manufacturing processes, transportation, energy consumption and disposal,” she said. “I recommend people make the best-informed decisions they can, while also remembering not to let it become overwhelming. Switch to LED Christmas lights Changing from incandescent to LED Christmas lights is good for both style and sustainability. LED lights reduce energy usage, are more durable and typically last longer than incandescent. Plus, they have come a long way over the past few years. “The criticism used to be that LEDs had a blue hue and were ‘cold’ compared to incandescent,” King said. “That isn’t really the case anymore. You have to be particular about what you purchase, but several companies offer lights that are virtually indistinguishable from vintage lights.” A clutter-free peaceful mindset While holiday decorations create a festive touch around the house, they can add to the clutter and busyness, which ultimately takes away the joy, King said. Decluttering and organization can help create a peaceful environment. “Most people enjoy Christmas decorations, but over the years we tend to accumulate a lot of them,” King said. “Sadly, for many, the thought of decorating for Christmas no longer brings feelings of excitement and joy. Instead, we dread going into the attic, dragging out the tree and boxes of ornaments, checking strands of lights, fixing broken bulbs, etc., only to know that we’ll have to put it all back in about a month. "Keep decorations that bring joy and let go of what no longer feels fulfilling can make a big difference in decreasing the excess while emphasizing what is important to you and your family," she said. By clearing both physical and mental space, families can better prioritize the activities and moments that truly matter. Reducing paper use It can be difficult to go fully paperless because of gift wrapping, but there are ways to reduce paper in the holidays from reusing materials or gifting experiences. “You can reuse paper shopping bags or even cut up the bags or other paper you have around the house and wrap gifts,” King said. Gifting experiences rather than physical items is another growing trend. “I find that many people are interested in receiving or gifting experiences, which can also reduce wrapping needs,” King said. “Not only does this minimize waste, but it also emphasizes shared moments over material possessions.” King noted that since COVID, there has been a trend to go paperless and people tend to be more comfortable with virtual communication and remote collaboration in general, which can also eliminate the need for Christmas cards and other paper products.
Dinosaurs in New Mexico Thrived Until the Very End, Study Shows
For decades, many scientists believed dinosaurs were already dwindling in number and variety long before an asteroid strike sealed their fate 66 million years ago. But new research in the journal Science from Baylor University, New Mexico State University, the Smithsonian Institution and an international team is rewriting that story. The dinosaurs, it turns out, were not fading away. They were flourishing. A final flourish in the San Juan Basin In northwestern New Mexico, layers of rock preserve a hidden chapter of Earth’s history. In the Naashoibito Member of the Kirtland Formation, researchers uncovered evidence of vibrant dinosaur ecosystems that thrived until just before the asteroid impact. High-precision dating techniques revealed that fossils from these rocks are between 66.4 and 66 million years old – placing them in the catastrophic Cretaceous-Paleogene boundary. “The Naashoibito dinosaurs lived at the same time as the famous Hell Creek species in Montana and the Dakotas... They were not in decline – these were vibrant, diverse communities.” – Daniel Peppe, Ph.D. “The Naashoibito dinosaurs lived at the same time as the famous Hell Creek species in Montana and the Dakotas,” said Daniel Peppe, Ph.D., associate professor of geosciences at Baylor University. “They were not in decline – these were vibrant, diverse communities.” Dinosaurs in their prime The New Mexico fossils tell a different story than originally thought. Far from being uniform and weakened, dinosaur communities across North America were regionally distinct and thriving. Using ecological and biogeographic analyses, the researchers discovered that dinosaurs in western North America lived in separate “bioprovinces,” divided not by mountains or rivers, but by temperature differences across regions. “What our new research shows is that dinosaurs are not on their way out going into the mass extinction,” said first author Andrew Flynn, Ph.D., ‘20, assistant professor of geological sciences at New Mexico State University. “They're doing great, they're thriving and that the asteroid impact seems to knock them out. This counters a long-held idea that there was this long-term decline in dinosaur diversity leading up to the mass extinction making them more prone to extinction.” Life after impact The asteroid impact ended the age of dinosaurs in an instant – but the ecosystems they left behind set the stage for what came next, the researchers said. Within 300,000 years of their extinction, mammals began to diversify rapidly, exploring new diets, body sizes and ecological roles. The same temperature-driven patterns that shaped dinosaur communities continued into the Paleocene, showing how climate guided life’s rebound after catastrophe. “The surviving mammals still retain the same north and south bio provinces,” Flynn said. “Mammals in the north and the south are very different from each other, which is different than other mass extinctions where it seems to be much more uniform.” Why the discovery matters today The discovery is more than a window into the past – it’s a reminder of the resilience and vulnerability of life on Earth. Conducted on public lands managed by the U.S. Bureau of Land Management, the research highlights how carefully protected landscapes can yield profound insights into how ecosystems respond to sudden global change. With a clearer understanding of the timeline of the dinosaurs’ final days, the study reveals not a slow fade into extinction but a dramatic ending to a story of flourishing diversity cut short by cosmic chance.
The Meaning Behind Hanukkah Meals
As families around the world prepare to celebrate Hanukkah, University of Rochester professor Nora Rubel can expound on the deeper stories behind the holiday’s foods, rituals, and evolving traditions. Rubel, a scholar of Jewish studies and chair of the Department of Religion and Classics, specializes in how Jewish identity is expressed through everyday practices and food. For instance, her work explores how dishes like latkes and sufganiyot (fried jelly donuts) carry meanings beyond the kitchen. “Food is one of the most powerful ways communities tell their stories,” Rubel says. “During Hanukkah, the foods we make and share help us remember the past, celebrate resilience, and connect with one another.” Hanukkah runs from Dec. 14 through Dec. 22 this year. Oil at the Heart of Hanukkah: Why Fried Foods Matter Many people recognize the holiday through its signature fried foods. But Rubel notes that these traditions developed over centuries and vary widely across cultures. • Ashkenazi Jews typically serve potato latkes. • Sephardic and Mizrahi communities prepare sufganiyot, bimuelos, zalabiya, and other fried sweets. • Some families incorporate dairy dishes, drawing on medieval interpretations of the Hanukkah story. What unites these foods, Rubel explains, is the symbolism of oil, which commemorates the miracle at the heart of the Hanukkah story. Many Ways to Celebrate Rubel emphasizes that Hanukkah is not a monolithic holiday. Its rituals, from lighting the menorah to singing blessings and exchanging gifts, vary across communities and generations. Some families add new traditions such as: • Hosting “latke tasting” gatherings • Experimenting with global Jewish recipes • Incorporating social justice themes into nightly candle-lighting • Sharing stories of family immigration and heritage “Hanukkah is a living tradition,” Rubel says. “It continues to evolve, and food is one of the ways people reinterpret what the holiday means for them today.” A Resource for Understanding Jewish Life Rubel’s broader scholarship focuses on American Jewish life, cultural memory, and how religious identities are shaped in the home as much as in the synagogue. She is a go-to resource for journalists covering holiday practices, regional Jewish cuisines, and the meaning behind rituals that shape the season, and is featured in “Family Recipe: Jewish American Style,” a new documentary now airing on PBS stations across the United States. Rubel is available for interviews throughout the Hanukkah period and beyond, and can speak to how traditions differ in Jewish communities around the world, the evolution of Hanukkah in American culture, and contemporary interpretations of rituals and identity.
