Young magmas on the moon came from much shallower depths than previously thought, new study finds
New research on the rocks collected by China's Chang'e 5 mission is rewriting our understanding of how the moon cooled. Stephen Elardo, Ph.D., an assistant professor of Geological Sciences with the University of Florida, has found that lava on the near side of the moon likely came from a much shallower depth than previously thought, contradicting previous theories on how the moon produced lavas through time. These samples of basalt, an igneous rock made up of rapidly cooled lava, were collected from the near side of the moon by the Chang’e 5 mission and are the youngest samples collected on any lunar mission, making them an invaluable resource for those studying the geological history of the moon. In order to get an estimate of how deep within the moon the Chang’e 5 lava came from, the team conducted high-pressure and high-temperature experiments on a synthetic lava with an identical composition. Previous work from Chinese scientists has determined that the lava erupted about 2 billion years ago and remote sensing from orbit has showed it erupted in an area with very high abundances of potassium, thorium and uranium on the surface, all of which are radioactive and produce heat. Scientists believe that, in large amounts, these elements generate enough heat to keep the moon hot near the surface, slowing the cooling process over time. “Using our experimental results and thermal evolution calculations, we put together a simple model showing that an enrichment in radioactive elements would have kept the Moon's upper mantle hundreds of degrees hotter than it would have been otherwise, even at 2 billion years ago,” explained Elardo. These findings contradict the previous theory that the temperature of the moon’s outer portions was too low to support melting of the shallow interior by that time and may challenge the hypothesis about how the moon cooled. Prior to this study, the generally-accepted theory was that the moon cooled from the top down. It was presumed that the mantle closer to the surface cooled first as the surface of the moon gradually lost heat to space, and that younger lavas like the one collected by Chang’e 5 must have come from the deep mantle where the moon would still be hot. This theory was backed by data from seismometers placed during the Apollo moon landings, but these findings suggest that there were still pockets of shallow mantle hot enough to partially melt even late into the moon’s cooling process. “Lunar magmatism, which is the record of volcanic activity on the moon, gives us a direct window into the composition of the Moon's mantle, which is where magmas ultimately come from,” said Elardo. “We don't have any direct samples of the Moon's mantle like we do for Earth, so our window into the composition of the mantle comes indirectly from its lavas.” Establishing a detailed timeline of the moon’s evolution represents a critical step towards understanding how other celestial bodies form and grow. Processes like cooling and geological layer formation are key steps in the “life cycles” of other moons and small planets. As our closest neighbor in the solar system, the moon offers us our best chance of learning about these processes. “My hope is that this study will lead to more work in lunar geodynamics, which is a field that uses complex computer simulations to model how planetary interiors move, flow, and cool through time,” said Elardo. “This is an area, at least for the moon, where there's a lot of uncertainty, and my hope is that this study helps to give that community another important data point for future models.”
What "Super Agers" Are Teaching Us About Growing Older
When I think about aging well, I don't see a number on a birthday cake. I see capacity. The ability to think clearly. To move with confidence. To stay curious. To laugh easily. To remember where I put my keys. (Okay, that last one is still aspirational.) That's why I teach 4 fitness classes a week and pay close attention to how I fuel my body. Not because I'm chasing youth, but because I've learned, both personally and professionally, that the way we move, eat, sleep, and cope influences how we feel... and how we show up for the people we care about. I don't want to live forever. I just want to live well while I'm here. Like many Boomers, I've been interested in the growing research on longevity. And let's be honest: Boomers have never been good at accepting "no" for an answer. Why would we start now, just because it's mortality asking? We're the generation that refused to compromise. Retirement? Optional. Slowing down? Negotiable. Death? We'd like to speak to the manager. This leads us to a fascinating group of scientists known as "Super Agers." Who Are Super Agers, Really? In research terms, Super Agers are adults over 80 whose cognitive abilities, especially memory, perform at levels expected of people in their 50s or 60s (Rogalski et al., 2013). But here's what I love most: they aren't superhuman. They're not top athletes. They're not biohackers living on kale foam and cold plunges at dawn. (Though if that's your thing, carry on.). They're everyday people who never disconnected from life. A striking Canadian example is Morry Kernerman, a Toronto violinist who kept on learning, hiking, and performing well into the ripe age of 101. His story embodies the spirit of Super Aging: it's not about dodging age, it's about refusing to stop living. In a CBC interview, Maury Kernerman doesn't sound like someone "trying to live longer." He talks like someone who's still interested in living, fascinated by the world, hungry for learning, and unwilling to stand still just because he might do something imperfectly. He also admits something that matters to a lot of readers: he wasn't always an exercise person. He started taking it seriously later in life and describes it as a "rear guard action" that hasn't stopped aging, but has helped him keep his capacity. One of the most poignant lessons: when we're afraid of doing the wrong thing, afraid of failing or being embarrassed, we stop. And standing still is what really costs us. Haven't you heard? Sitting is the new Smoking!! What the Science Is Showing Us Canadian and U.S. researchers, at Western University and Northwestern University, are discovering something significant. Not a pill. Not a quick fix. A system. Angela Roberts (Western University) explained that the Canadian arm of the research isn't relying only on lab snapshots. Participants are sent home with wearable devices so researchers can monitor real-world activity patterns continuously (24 hours a day) over multi-week periods (CBC News, 2024 - https://www.cbc.ca/news/health/superager-centenarians-brain-second-opinion-9.7049411). That design matters because it turns "healthy aging" from a vague concept into measurable behaviours: how much movement you get, how intense it is, how consistent it is, and how it fits into the rhythm of normal life. Super Agers typically stay active, remain mentally sharp, maintain close relationships, handle stress effectively, sleep well, and keep a generally positive attitude (Rogalski et al., 2013 - https://doi.org/10.1162/jocn_a_00300; Sun et al., 2016 - https://doi.org/10.1523/JNEUROSCI.1492-16.2016) Their brains display thicker cortical areas linked to attention and memory, experience slower atrophy rates, have fewer Alzheimer's markers, and show stronger neuronal connections (Gefen et al., 2015 - https://doi.org/10.1523/JNEUROSCI.2998-14.2015; Harrison et al., 2012 - https://doi.org/10.1017/S1355617712000847) A Data Point Worth Remembering When It Comes to Longevity From the wearables, the research study observed that many 80-year-olds in the study, both "super agers" and the control group, were averaging about 25 to 30 minutes of exercise a day (roughly aligned with Canadian movement guidelines). The difference wasn't that super agers moved a little more. The study showed that they got about 30% more of the kind of movement that raises heart rate, what researchers call moderate-to-vigorous physical activity In plain language: it's not just steps. It's getting your engine up into that slightly breathy zone on purpose, most days. There's no single longevity switch. It's a belt-and-suspenders approach: multiple protective habits working together over decades. Let's Talk About Weight (Without Losing Our Minds) People often ask: Should Super Agers be skinny? Or a little plump? The research answer is surprisingly dull (and comforting): Neither. Super Agers come in all sizes. There is no evidence that they share a specific body weight or BMI. What matters much more than the scale is stability, strength, and body composition (Stenholm et al., 2008). Obesity Shows Up Consistently in the Research Midlife obesity is associated with an increased risk of dementia later in life. Several large studies indicate that obesity (BMI ≥30) during midlife raises dementia risk by 33 to 91% compared to individuals of normal weight (Kivipelto et al., 2005; Qizilbash et al., 2015) However, in older age, unintentional weight loss often signals frailty or illness. Weight loss in later life is linked to faster cognitive decline and higher risk of death (Diehr et al., 2008) Being underweight increases the risk of death. Studies consistently indicate that underweight older adults (BMI <20) have 2 to 3 times the all-cause mortality risk compared to those with a normal weight, with one study reporting a 34% higher risk of dementia (Diehr et al., 2008). A slightly higher BMI in later life may actually be protective, especially if muscle mass is maintained. The "obesity paradox" demonstrates that overweight and mild obesity in older adults (ages 65+) are often linked to a lower risk of mortality, particularly from non-cardiovascular diseases (Natale et al., 2023). So, the prescription is clear: avoid extremes. Not so skinny you could use a Cheerio as a hula hoop, and not so plump that tying your shoes feels like a full-contact sport. Here's What Truly Matters: Muscle Mass Strength defends the brain, maintains balance, boosts metabolism, and offers resilience during illness or stress (Peterson & Gordon, 2011) "Skinny-fat", low muscle, higher fat, is actually worse for aging than carrying a bit more weight with muscle beneath (Prado et al., 2012). Super Aging isn't about shrinking yourself. It's about supporting the structure you live in. Sleep: The Quiet Superpower If movement is the main act, sleep is the stage crew ensuring the entire show runs smoothly. Sleep isn't just one thing. It's a cycle (Walker, 2017). The Stages of Sleep (a quick, non-boring tour) Light sleep: The warm-up. Easy to wake from. Necessary, but not enough by itself. Deep sleep: The body's main repair mode. This is where physical repair occurs: muscle recovery, immune support, hormone regulation (Scullin & Bliwise, 2015) (Walker, 2017). REM sleep: The brain's spa. Memory consolidation, emotional regulation, creativity, and learning all occur here (Scullin & Bliwise, 2015) (Walker, 2017). Missing deep sleep leaves your body feeling exhausted. Missing REM causes your brain to become fragile and foggy (Mander et al., 2017). Super Agers tend to guard their sleep, though not perfectly, deliberately (Mander et al., 2016). Consistent bedtimes, morning sunlight, daily activity, and relaxing evenings appear repeatedly. For some people, slow-release melatonin or magnesium can help improve sleep maintenance (Ferracioli-Oda et al., 2013). However, the greatest benefits often come from simple routines: consistency, darkness, cooler rooms, and avoiding phone use at 10 p.m. Sleep isn't a luxury. It's essential brain maintenance (Mander et al., 2017). Stress: The Real Villain Chronic stress is like kryptonite for cognitive health (McEwen & Sapolsky, 1995). The main source of stress is not accepting what is. We argue with reality, and we lose every time. We revisit conversations. We resist change. We attempt to control others. Super Agers appear more accepting, not resignation, but realism (Sun et al., 2016) Here are some practical strategies to consider: Let them. (Thank you, Mel Robbins.) People will be people. You don't need to manage them. Save your energy for what truly matters. And remember: what people think of you... is none of your business. Calm isn't passive. Calm is protective. Gratitude also plays a role. Many Super Agers exhibit a distinct emotional tone: more grateful, less gripeful (Hill & Allemand, 2011) Life wasn't simpler; they simply didn't let bitterness steer the way. Relationships and Quality of Life: The Real Gold Standard Super Agers don't have more friends; they have deeper ones. Strong relationships are linked to better emotional regulation and preserved brain regions. (Cacioppo & Cacioppo, 2014) (Holt-Lunstad et al., 2010) And this isn't about extending life. It's about quality of life: cognitive, physical, and emotional well-being. Because no one wants a farewell-to-life party where nobody shows up because you've been miserable, bitter, or exhausting to be around (thank you, BR). Strong body. Clear mind. Warm relationships. A sense of humour that endures gravity. That's the win. 3 Practical Takeaways to Steal this Week If you want the super-ager approach without turning your life into a science experiment, here are three low-drama moves: Add intensity, not just activity. Keep your regular walk, but pick one segment to walk faster, take a hill, or add short brisk bursts. Your heart rate is the clue. Keep a learning thread running. Music, audiobooks, a class, a museum habit, a book club, anything that keeps your mind taxed in a good way and makes you feel curious again. Make "don't stand still" a rule. If you're avoiding something because you might look silly (a dance class, a new hobby, a new friend group), that's exactly the place to lean in, gently, but on purpose. Super Agers aren't chasing youth. (No one needs to see me in low-rise jeans again.) They're cultivating engagement. (Do you want to dance?) They move. They learn. They sleep well. They stay positive. They accept what is. They remain connected. They rely on the belt and suspenders. And most importantly, they don't wait for permission to live life to the fullest at any age. Yes, biology will win eventually. None of us gets out of this alive. But the real victory isn't in defeating what we can't control. It's in mastering what we can, for as long as we can, and living fully right up until biology takes its final bow. Don't Retire...ReWire! Sue Want more of this?

A future in pharmacy, made possible by support and mentorship
A freshman chemistry major from Hinesville, Georgia, Geovanii Pacheco already has his sights set on a career in pharmacy. His ambition is rooted not just in a love for science, but in personal experience. Growing up, his family spent countless hours navigating prescriptions and insurance coverage for his older brother, Devin, who has autism. During those moments, one pharmacist consistently stood out. This was someone who advocated for his family, helped them through paperwork and made sure Devin got the medication he needed. “It really resonated with me,” Pacheco said. “As a pharmacist, I’d like to embody what she did for us, for others as well.” That goal brought Pacheco to Georgia Southern University where he is now supported by the National Science Foundation’s S-STEM Scholarship Program Award. This is a nearly $2 million grant designed to support Pell-eligible students pursuing degrees in biochemistry, biology, chemistry, geosciences, mathematics, physics or sustainability science. For Pacheco, the program has been nothing short of life-changing. “I can say that I’m not going to college with any financial stress,” he said. “I have no money coming out-of-pocket.” Administered through Georgia Southern’s College of Science and Mathematics, the federally funded program provides last-dollar scholarships that cover remaining costs after Pell Grants and other aid are applied. In addition to financial support, the program pairs students with dedicated faculty mentors and offers structured programming aimed at retention, professional development and long-term success. Sara Gremillion, Ph.D., professor of biology and principal investigator on the grant, said the goal is to ensure that students don’t just enroll in college, but that they also thrive once they arrive. “They may not have a strong expectation about what to expect in college,” said Gremillion. “This program not only removes financial barriers, but it also surrounds students with the support they need to navigate college and plan for their future.” Pacheco has felt that impact from day one. Thanks to the program, he moved into his residence hall a week early to attend a one-week Basebamp program to jump start his college experience. There, he met fellow scholarship recipients and connected with his faculty mentor before classes even began. His mentor, Shainaz Landge, Ph.D., associate professor of chemistry, has helped connect Pacheco with opportunities from joining the Student Affiliates of the American Chemical Society to learning about upcoming pre-pharmacy organizations and undergraduate research. “Students such as Geovanii serve as prime examples of the fulfillment derived from mentorship and teaching,” said Landge. “Their growth and engagement highlight the critical role that effective mentorship plays in fostering both academic development.” That blend of mentorship and financial support is exactly what the grant was designed to provide. Over five years, the program will serve dozens of students in eligible majors such as chemistry, biology, biomedical science, biochemistry, physics, mathematics, sustainability science and geoscience. Each student receives individualized scholarship support, up to $15,000 per year, based on need, along with a faculty mentor who stays with them throughout their undergraduate journey. For Pacheco and his family, the scholarship brought immediate relief. He vividly remembers opening the acceptance email with his mother and scrolling down to see the financial aid details. “She was tickled, let me tell you,” he said. “It lifted so much stress off her shoulders. It was life-changing.” Applications to be part of the next cohort of COSM S-STEM Scholars are open until Feb. 1, 2026. Eligibility requirements, necessary documentation and other information can be found at this webpage.

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. Featured Experts Harshi Sritharan, MSW, RSW – Psychotherapist specializing in ADHD, anxiety, insomnia and digital dependency. She helps teens and adults understand how doomscrolling and passive feeds hijack dopamine and mood, and teaches practical shifts toward more intentional, “active” tech use. Eli Singer – Founder of Offline.now and author of Offline.now: A Practical Guide to Healthy Digital Balance. He brings proprietary data on digital overwhelm and the “confidence gap,” and shows how 20-minute “micro-wins” like upgrading one chunk of passive screen time can change people’s relationship with their phones without extreme detoxes.

Do Teens Secretly Want Phone Boundaries More Than Adults Think?
Ask a parent about phones and teens, and you’ll hear the same story: “They’re glued to that thing and don’t care.” But when you ask teens themselves, a different picture emerges. A recent Pew Research Center study found that about 95% of U.S. teens have access to a smartphone — and around 4 in 10 say they spend too much time on it. (Pew Research Center) Coverage of the same data notes that over 70% of teens say they feel happiness or peace when they’re not tethered to their device, even as they rely on it for social life. (KTUL) Psychotherapist Harshi Sritharan, MSW, RSW, who works with teens and young adults on digital dependency, sees that ambivalence every day. “I have 12- to 15-year-olds who come in and say, ‘I know I’m kind of addicted to my phone,’” she says. “When a teenager says that, I’m relieved — it means we have something to work with.” She stresses that most young people don’t actually want to be left alone with endless scrolling — they want help making sense of it. Teen Limits Work Better Than Parents Think New data suggests that reasonable limits can help and that many teens benefit when parents set them thoughtfully. A tool parents can use is collaborative problem solving. This involves parents and teens working together to come up with a plan for the best strategies that combat everyone’s concerns while compromising. A 2024 Springtide Research Institute survey of 1,112 13-year-olds found that teens whose parents limit their screen time are less likely to be heavy users: only 32% of those with limits use their phone 5+ hours a day, compared with 55%of those with unlimited time. Just 24% of teens with limits said they’d felt like they had a mental health problem, versus 32% with no limits.(Springtide Research Institute) In other words, boundaries are mildly protective, not cruel, especially when they’re explained instead of imposed. Sritharan cautions against “no phones ever” rules that ignore school and social realities: “We can’t make blanket statements of ‘no screens’,” she says. “We shape how kids use devices so they can still get things done and spend more time engaging with their family.” That might mean agreeing on tech-free windows (like family dinners or the hour before bed) and tech-friendly ones (like a 45-minute bus ride where a teen can listen to music or message friends). Teens Are Leading a Quiet “Cutback” Movement Parents often feel like the only ones craving less screen time, but surveys show Gen Z is already trying to dial things down. A global survey cited by Tech Times and ExpressVPN found that about 46% of Gen Z are actively taking steps to limit their screen time, more than older generations.(Tech Times) Another U.S. poll commissioned by ThriftBooks found half of respondents are cutting back on screens, with Gen Z and millennials leading — and 84% adopting analog habits like printed books, paper planners and board games.(New York Post) Reporting on the “board game revival” among Gen Z echoes the same trend: young people are consciously seeking offline, face-to-face ways to connect.(Woke Waves) For Offline.now experts, this adds up to a simple message: teens aren’t fighting all boundaries — they’re fighting feeling controlled or misunderstood. Parents as Co-Pilots, Not Phone Police Executive Function Coach Craig Selinger, M.S., CCC-SLP says the real leverage point isn’t just new rules; it’s how parents model and co-create them. “If you want behavior change in kids, start with the parent model,” he says. “A 12-year-old will not put their phone away at dinner if their parents won’t.” He encourages families to focus on “little moments” where phones quietly block connection — especially car rides and in-between times when kids might naturally open up: “In the car, your kid is trapped with you,” Selinger says. “That’s when they start talking. If they’re on their phone the whole time, you lose those big conversations hiding in the boring moments.” Both experts emphasize co-designing boundaries with teens: agreeing together on tech-free times and how late-night scrolling affects mood and school performance. When teens feel heard — and see adults following the same rules — boundaries feel less like punishment and more like shared protection. For journalists, the story isn’t “teens vs phones” or “parents vs teens.” It’s that both sides are quietly overwhelmed, and many young people are more open to limits than adults realize — if those limits are built with them, not against them.

Study: What makes a smell bad?
You wouldn’t microwave fish around your worst enemy — the smell lingers both in kitchen and memory. It is one few of us like, let alone have positive associations with. But what makes our brains decide a smell is stinky? A new study from UF Health researchers reveals the mechanisms behind how your brain decides you dislike — even loathe — a smell. Or as first author and graduate research fellow Sarah Sniffen puts it: How do odors come to acquire some sort of emotional charge? In many ways, our world capitalizes upon the importance of smells to influence emotions, running the gamut from perfumes to cooking and even grocery store design. “Odors are powerful at driving emotions, and it’s long been thought that the sense of smell is just as powerful, if not more powerful, at driving an emotional response as a picture, a song or any other sensory stimulus,” said senior author Dan Wesson, Ph.D., a professor of pharmacology and therapeutics in the UF College of Medicine and interim director of the Florida Chemical Senses Institute. But until now, researchers have puzzled over what circuitry connects the parts of the brain vital to generating an emotional response with those responsible for smell perception. The team started off with the amygdala, a brain region that curates your emotional responses to sensory stimuli. Although all our senses (sound, sight, taste, touch and smell) interact with this small part of your brain, the olfactory system takes a more direct route to it. “This is, in part, what we mean when we say your sense of smell is your most emotional sense,” Sniffen said. “Yes, smells evoke strong, emotional memories, but the brain’s smell centers are more closely connected with emotional centers like the amygdala.” In the study, researchers looked at mice, who share neurochemical similarities with people. They can learn about odors and categorize them as good or bad. After observing their behavior and analyzing brain activity, the team found two genetically unique brain cell types that allow odors to be assigned into a bucket of good feelings or bad feelings. Initially, the team expected that one cell type would generate a positive emotion to an odor, and another would generate a negative emotion. Instead, the brain’s cellular organization gives the cells the capability of doing either. “It can make an odor positive or negative to you,” Wesson said. “And it all depends upon where that cell type projects in your brain and how it engages with structures in your brain.” But why is knowing more about how we categorize smells important? Well, for starters, smells — and our reactions to them — are a part of life. Sometimes, however, our reactions to them can be outsized, or take on a negative association so strong it disrupts how we live. “We’re constantly breathing in and out and that means that we’re constantly receiving olfactory input,” Sniffen said. “For some people that’s fine, and it doesn’t impact their day-to-day life. They might even think, ‘Oh, odors don’t matter that much.’ But for people who have a heightened response to sensory stimuli, like those with PTSD or anxiety or autism, it’s a really important factor for their day-to-day life.” In the future, the research could help clinicians adjust for heightened sensory response that some people struggle with in their everyday lives, Wesson added. One example? A patient associating a clinic’s smell with transfusions that made them queasy. Based upon the receptor systems in these specific brain pathways, the team members believe they might be able to change those associations. Potentially, medications could suppress some of these pathways’ activity to allow you to overcome stressful and aversive emotional responses. Conversely, these pathways could be activated to restore enjoyment to things that people might have grown indifferent to — like those who lose their appetite from illness. “Emotions in part dictate our quality of life, and we’re learning more about how they arise in our brain,” Wesson said. “Understanding more about how our surroundings can impact our feelings can help us become happier, healthier humans.” This research was supported by funding from the National Institute on Deafness and Other Communication Disorders and the National Institute on Drug Abuse. Sarah Sniffen was supported by a fellowship from the National Institute on Deafness and Other Communication Disorders.
Six University of Delaware online graduate degree programs are ranked among the best in the nation by U.S. News & World Report in its 2026 U.S. News Best Online Programs, released Jan. 27, 2026. Both UD’s online master’s in education and online MBA ranked among the top 10% of their respective programs, at No. 25 and 26, respectively. Announced on Jan. 6, the online MBA program recently rose nine spots to No. 32 in the Poets&Quants 2026 Online MBA rankings. UD’s online master’s in nursing program ranked No. 35 out of 209 programs, rising 99 places over the past year. New for UD, the online master’s in educational/instructional media design program was recognized by peers at No. 11 in this education specialty ranking. UD’s online master’s in computer information technology program and online master’s in engineering ranked No. 64 in their respective areas. “These latest rankings recognize the expertise and dedication of our faculty and staff in delivering UD’s outstanding online graduate programs,” Interim Provost Bill Farquhar said. “We are committed to continually enhancing these programs and all the transformative opportunities that enable our students to meet their educational and career goals throughout their lives.” U.S. News selects several factors, known as ranking indicators, to assess each program in the categories outlined above. A program's score for each ranking indicator is calculated using data that the program reported to U.S. News in a statistical survey and from data collected in a separate peer assessment survey. This year’s edition evaluates more than 1,850 online bachelor’s and master’s degree programs using metrics specific to online learning. The rankings include only degree-granting programs offered primarily online by institutions with accreditation from recognized commissions. While the overall rankings methodology remains largely unchanged, U.S. News reported increased participation in this year’s data collection cycle, with more programs submitting statistical data and completing peer assessment surveys.

How Higher Ed Should Tackle AI
Higher learning in the age of artificial intelligence isn’t about policing AI, but rather reinventing education around the new technology, says Chris Kanan, an associate professor of computer science at the University of Rochester and an expert in artificial intelligence and deep learning. “The cost of misusing AI is not students cheating, it’s knowledge loss,” says Kanan. “My core worry is that students can deprive themselves of knowledge while still producing ‘acceptable work.’” Kanan, who writes about and studies artificial intelligence, is helping to shape one of the most urgent debates in academia today: how universities should respond to the disruptive force of AI. In his latest essay on the topic, Kanan laments that many universities consider AI “a writing problem,” noting that student writing is where faculty first felt the force of artificial intelligence. But, he argues, treating student use of AI as something to be detected or banned misunderstands the technological shift at hand. “Treating AI as ‘writing-tech’ is like treating electricity as ‘better candles,’” he writes. “The deeper issue is not prose quality or plagiarism detection,” he continues. “The deeper issue is that AI has become a general-purpose interface to knowledge work: coding, data analysis, tutoring, research synthesis, design, simulation, persuasion, workflow automation, and (increasingly) agent-like delegation.” That, he says, forces a change in pedagogy. What Higher Ed Needs to Do His essay points to universities that are “doing AI right,” including hiring distinguished artificial intelligence experts in key administrative leadership roles and making AI competency a graduation requirement. Kanan outlines structural changes he believes need to take place in institutions of higher learning. • Rework assessment so it measures understanding in an AI-rich environment. • Teach verification habits. • Build explicit norms for attribution, privacy, and appropriate use. • Create top-down leadership so AI strategy is coherent and not fractured among departments. • Deliver AI literacy across the entire curriculum. • Offer deep AI degrees for students who will build the systems everyone else will use. For journalists covering AI’s impact on education, technology, workforce development, or institutional change, Kanan offers a research-based, forward-looking perspective grounded in both technical expertise and a deep commitment to the mission of learning.

One year ago, after a campaign that toppled Bashar al-Assad's repressive dictatorship, Ahmed al-Sharaa assumed the Syrian presidency. Since then, the former rebel commander has worked to establish his credentials as a statesman, winning the support of regional powers like Türkiye, Saudi Arabia and Qatar—as well as recognition from the White House. Yet al-Sharaa and his transitional government have not been immune from criticism, particularly over their handling of domestic affairs. Samer Abboud, PhD, director of the Center for Arab and Islamic Studies at Villanova University, is an expert on modern Syria and the wider Middle East. A year into al-Sharaa's presidency, he believes the provisional government has made incredible strides in some areas, like international diplomacy, while struggling to find its footing in others. "There's no doubt that Syria's external image is becoming more positive. We see this kind of charm offensive, with President al-Sharaa taking to the world stage," says Dr. Abboud. "Also, most of the regional actors are very fond of al-Sharaa and were very happy for the Assad regime to have fallen. So, there's this external presentation of a transition government that is legitimate and has support, and I think that's largely true. "The problem in Syria right now, of course, is what's happening internally. To begin, across the country, you have completely collapsed infrastructure—limited electricity, restricted access to running water and unreliable internet." Much has been made of economic sanctions' role in contributing to these internal issues, with Western governments having historically limited the amount of aid and investment that could enter Syria. However, while Dr. Abboud sees these measures' elimination as crucial to the nation's progress, he also contends that ending restrictions alone is not enough to ensure the country's long-term stability and prosperity. Of particular concern, according to the professor, is the al-Sharaa administration's persistent claim "that 'free markets' could and would be a cure-all." As he explains, "The problem is that there's literally no evidence to demonstrate that private enterprise is interested in social betterment in reconstruction cases. You can't rebuild a state and a society on the profit logic. When you look at Lebanon, after all the wars Lebanon endured, what did free markets—without a strong public sector—do for that country? Roughly 80 percent of Lebanese people live in poverty." Beyond the troubles surrounding economic growth and infrastructural development, there also exist a series of fractures along ethnic and ideological lines. Wide swaths of Syria are currently controlled by militias with agendas at odds with that of the provisional government, and despite making inroads with one significant bloc of dissent (the Kurdish-led Syrian Democratic Forces), tensions are exceedingly high. Furthermore, a number of groups remain suspicious of the president and his intentions due to his past affiliation with Hayat Tahrir al-Sham, a Sunni Islamist group that traces its roots to al-Qaeda. Navigating this delicate situation with poise and precision is something that al-Sharaa needs to master, contends Dr. Abboud. And, over the course of the past several months, it seems Syria's new leader has started to refine the skill. "To illustrate, last year, at least 25 people were killed in a bombing at the Mar Elias Church in Damascus, and President al-Sharaa did not go to the site. In addressing the incident, he also didn't use the language of martyrdom, which is what you would typically do for any person—Christian or Muslim—who died in this context," says Dr. Abboud. "In June, however, they arrested the culprits, and he went and met the patriarch and went inside the church, and they publicized it. "The first time, he was too worried about these internal influences—of being perceived by his base as having moderated his views. Right now, he very much finds himself caught in a balancing act, working to temper the forces that are compelling him to possibly do something that could worsen an unstable situation. But I do think that the two contrasts [represented in the Mar Elias Church episode] suggest that the president is learning and gradually figuring out how to do politics a bit differently." In this vein, Dr. Abboud feels the next phase in al-Sharaa's evolution should center on reckoning with the history of the country's late civil war and encouraging a dialogue between those who supported the Assad regime and those who sought to overthrow it. In the professor's estimation, this step is essential to achieving a lasting peace in Syria. "Currently, there are some memory projects and knowledge projects that are happening, but those are not led or facilitated by the state. And that's troublesome, given what we've seen in other conflict contexts," he says. "In Lebanon, for instance, the state has amnesia. The civil war is not in the textbooks, officials don't talk about it, and it's not commemorated nationally. But then, in many ways, the narrative of how it happened—who are the victims, who are the perpetrators—can totally shape people's lives." Still, while much economic, social and humanitarian work remains to be done, Syria today finds itself in a position unlike any it's occupied in decades' time: one marked by possibility. "In general, I envision an extended period of grace for the government and an extended period of hope," concludes Dr. Abboud. "Syria did not have a future under the Assad regime. Or it had a future, but one characterized by generations of isolation. Today, people, both inside and outside Syria, have an entirely different outlook."
