    Emery N. Brown, Massachusetts Institute of Technology - Your Brainstem's Bundles

    Brainstems are hard to image because of their size and density, but is that about to change? Emery N. Brown, professor of neuroscience at the Massachusetts Institute of Technology, says yes. Faculty Bio: Emery N. Brown, M.D., Ph.D. is the Edward Hood Taplin Professor of Medical Engineering and Computational Neuroscience at MIT in The Picower Institute for Learning and Memory; the Warren M. Zapol Professor of Anaesthesia at Harvard Medical School; and an anesthesiologist at Massachusetts General Hospital. Dr. Brown is a neuroscientist-anesthesiologist-statistician whose research has contributed toward understanding how anesthetics act in the brain. In his statistics research he has developed signal processing algorithms to solve important data analysis challenges in neuroscience. For his work he received the National Medal of Science in January 2025. Transcript: Don’t sleep on the importance of your brainstem. This part of your brain is a vital conduit between your body and the rest of the brain. The signals that flow through bundles of nerve fibers there govern essential functions such as consciousness, sleep, breathing, heart rate and motion.While we know that the brainstem is absolutely crucial and that damage there can present patients with major problems, we haven’t had good ways to image and keep track of the health of its fiber bundles for reasons including how small and densely packed they are.But earlier this year, my colleagues and I, led by my graduate student Mark Olchanyi, developed a new way to clearly see brainstem fiber bundles in diffusion MRI imaging. The Brainstem Bundle Tool uses AI to analyze MRI images from patients, enabling us to track the size and structural integrity of eight distinct nerve fiber bundles.In the study we showed that the tool could reliably spot different effects on fiber bundles from Alzheimer’s disease, Parkinson’s disease, multiple sclerosis and traumatic brain injury. Mark even used the tool to retrospectively look at the bundles in a patient who had been in a coma for seven months before recovering. He was able to show how the bundles were healing during that time.We are hopeful that this innovation, developed at MIT, Harvard and Massachusetts General Hospital can transform the brainstem from being something of a mystery into a brain structure essential for understanding normal brain physiology as well as brain diseases and injury.

    Fabian Klenner, University of California, Riverside - How Do We Search for Life Beyond Earth?

    How do we search for life beyond Earth? Fabian Klenner, assistant professor of planetary sciences at the University of California, Riverside, explores the cosmos to find out. Faculty Bio: Fabian Klenner is an Assistant Professor of Planetary Sciences in the Department of Earth and Planetary Sciences at the University of California, Riverside. He received his Ph.D. from Freie Universität Berlin (FUB) in Germany. Prior to joining UC Riverside, he held postdoctoral appointments at FUB and the University of Washington. Being involved in various space missions, Fabian Klenner’s research centers around ocean worlds in the solar system. His research group addresses astrobiological questions to advance our understanding of extraterrestrial geochemical processes and the detection of potential life beyond Earth. Transcript: Are we alone in the universe? This is one of the most intriguing questions of mankind. We only know of one example of life, that is, life on Earth. In order to make life, you need the right ingredients, and the main ingredients of life on Earth are liquid water, enough energy and organic chemistry. Organic chemistry refers to chemical processes that involve carbon-containing compounds. When we search for life beyond Earth, we can start by searching for liquid water and then we analyse what is in the water.Within the solar system, so-called ocean worlds are at the forefront of the search for life. Ocean worlds are objects that harbour large bodies of liquid water. Examples include Saturn’s moon Enceladus and Jupiter’s moon Europa. The oceans on these moons do not exist at the surface and instead they are hidden below thick ice crusts in the subsurface. However, Enceladus, and maybe also Europa, emit material from their oceans through geysers into space. Such emissions provide us a unique opportunity to sample an ocean beyond Earth. This can be done by spacecraft flying to these moons and analysing the emitted material.My research at the University of California in Riverside combines spacecraft observations, laboratory experiments and computational efforts to advance our understanding of chemical processes on ocean worlds in the solar system and the detection of potential life beyond Earth. In a recent study, we re-analysed data that was recorded by NASA’s and ESA’s Cassini spacecraft in the geysers of Enceladus. The data contained clear evidence of a variety of organic compounds that came from Enceladus’s subsurface ocean. These organic compounds open up many new pathways for chemistry that may occur inside Enceladus and bolster the case that Enceladus could support life.

    Harry Reis, University of Rochester - How to Feel Loved

    Do you feel loved? Harry Reis, professor of psychology at the University of Rochester, examines why most do not. Faculty Bio: Harry Reis, a professor of psychology at the University of Rochester, is one of the world’s leading experts on relationships and connection and has studied the complexities of well-being and love in depth. His research examines the factors that influence the quantity and closeness or social interaction, and the consequences of different patterns of socializing for health and psychological well-being. Truly feeling loved, he has found, differs widely from the actions that we usually associate with loving, being loved, and falling in love. Transcript: Most people want to BE loved, but above all, they want to FEEL loved. Ask yourself: Do you feel loved as often as you would like? Do you feel loved by the people you want to feel loved by? A book I co-authored with Sonja Lyubomirsky, How to Feel Loved, is meant to help people find, keep, and grow the love they feel.In our research, roughly two-¬thirds of a random sample of Americans wantedto feel more loved or loved more often.Studies show that not feeling loved is the root of the so-called loneliness epidemic; it hampers performance at school and work; it harms our health and well-being, and it even predicts dying sooner. Feeling loved is not a luxury, it’s a necessity.Ironically, some of the most common ways we try to feel more loved can make things worse, not better:For example, we try to make ourselves appear more attractive and successful;We spotlight our positive qualities while hiding our weaknesses and vulnerabilities.But feeling loved is not about changing yourself or making another person love you. It’s about changing the conversation.The pathway to feeling more loved begins with conversations that help your partner feel more loved. Listen attentively to what they say and show genuine curiosity into what makes them tick. Be non-judgmental and open-hearted. This approach invites your partner to reciprocate your curiosity and caring. When you help another person feel loved, they become interested in you. When this happens, it is important to share your full self: not just your accomplishments and strengths but also your shortcomings: the authentic person you believe yourself to be. By opening up, you allow yourself to be seen and understood.Adopting the right mindset – the attitude with which you approach others – creates the conditions in which love and connection can flourish.

    Craig Clements, San Jose State University - Understanding the Science of Wildfires and Extreme Fire Behavior

    We have much to learn about wildfires. Craig Clements, professor and chair of the Department of Meteorology and Climate Science at San Jose State University, uses a research lab on wheels to get close to the action. Faculty Bio: Craig Clements is a professor and chair of the Department of Meteorology and Climate Science at San José State University, where he is director of the Wildfire Interdisciplinary Research Center (WIRC) and director of the Fire Weather Lab. His research focuses on the micro-meteorology and behavior of wildland fires, mountain and boundary-layer meteorology, air pollution and turbulence.His research and teaching focus includes wildfire meteorology and fire weather, extreme fire behavior, mountain and boundary-layer meteorology, turbulence, and meteorological instrumentation. Transcripts: Californians are concerned about the growing threat of extreme wildfires, such as the recent Pacific Palisades and Altadena fires, that resulted in loss of life and extensive property damage. But residents of other states, including Washington, Oregon, Texas and parts of the Midwest and Southeast are now facing increased dangers from wildfires.My research seeks to improve accurate predictions in wildfire science, a field that wasn’t even on the map when we began our work well over a decade ago. Since then, we launched the mobile fire weather lab--which allows us to travel to the fires--similar to the ways scientists have studied hurricanes and tornadoes--learning about their formation and dynamics for better prediction models. We’re really the only team that’s done this for wildfires, which are significantly under-sampled compared to all other atmospheric phenomena.Our “research lab on wheels” consists of a pair of lifted pickup trucks, both four-wheel drive, with state-of-the-art equipment, including Doppler LIDAR surface weather equipment and an upper air sounding system--basically a weather balloon--satellite radio to communicate with fire personnel, a suite of laptop computers, and other useful gear. Our team drives around forests and mountains using the two trucks in tandem to study fire dynamics and wildfire plumes. We gather, examine and provide useful data, much like that which is collected in severe weather and hurricane research, to better understand key elements of fire behavior and to test models and forecast systems. We collect information from the ground, but also from airborne assets and remote sensing satellites.When it comes to wildfires, it’s notable that their frequency and intensity is the result of a complex interplay of climate, topography, and vegetation. Extreme wildfires bring these elements and other factors together in ways that can become so powerful that they can actually create their own weather.

    Clinton Haarlem, Trinity College - How Ecology and Lifestyle Drives an Animal's Speed of Sight

    Not every animal experiences the world at the same speed. Clinton Haarlem, postdoctoral research fellow at Trinity College, looks to visual processing speeds to explain why. Faculty Bio: Dr. Clinton Haarlem’s research focuses on variation in visual perception rates, both across species and across individuals. Clinton’s work is multidisciplinary and incorporates zoology, ecology and neuroscience to explore the dynamic interplay between sensory perception, behaviour and the environment. Transcript: Have you ever wondered why it is so difficult to swat a fly? One of the reasons is because flies can see events happening in the world more than twice as fast as we can, allowing them to react to situations with incredible speed. But why do different animals see the world at different rates, and how does this shape their interactions with the world? These are the types of questions we aim to address with our research. Using a metric called the “critical flicker fusion threshold,” we can measure how fast the visual processing abilities of animals are. We can then compare how species with different visual processing rates differ in their physiology, their behaviour and the types of habitats they occupy. For example, we have found that species that live fast paced lifestyles, like those that are highly manoeuvrable or those that actively chase after prey, tend to possess much faster perception than more sluggish species or species that graze on stationary foods. Flying species in particular have extremely fast vision. After all, a peregrine falcon diving at over 300 km/h through the air needs pinpoint precision and expert timing to catch its prey. A high visual temporal resolution allows it to do just that. Our work informs how sensory systems are not only highly influenced by evolutionary background, but also by the environment and by behaviour. This helps us develop a greater understanding of how species living in similar habitats may have an entirely different experience of the world around them. Gaining a better understanding of the sensory worlds of animals is not only valuable in behavioural - and ecological research, but it can also help to improve conservation strategies and animal welfare practices by fostering more tailored - and individualized approaches.

    Naomi Baron, American University - Negotiating How Much AI Reads for Us

    What are the consequences of letting AI read for us? Naomi Baron, professor emerita of linguistics at American University, explores this issue. Faculty Bio: Naomi S. Baron is Professor Emerita of Linguistics at American University in Washington, DC. She is a Stanford PhD and has been a Guggenheim Fellow, Fulbright Fellow, and Visiting Scholar at the Stanford Center for Advanced Study in the Behavioral Sciences. Author of eleven books, she has done research in a wide swath of areas, including child language acquisition, the history of English, writing as a form of linguistic representation, reading, and artificial intelligence. The emergence of email, mobile phones, and social media led her to explore how online and mobile communication reshape our linguistic interactions (Alphabet to Email, 2000, and Always On, 2008). Two subsequent books (Words Onscreen, 2015, and How We Read Now, 2021) drew on her empirical studies of how users view print versus digital screens as reading media.More recently, Professor Baron has focused on the ways in which artificial intelligence is reshaping what it means to write and read. Who Wrote This? (2023) broached the challenges we face when AI becomes our writing or editing surrogate. Her new book, Reader Bot (2026), takes on the complementary issue of outsourcing human reading to a large language model. Transcripts: Since writing first emerged roughly 5,000 years ago, motivations for reading have proliferated. From legal declarations to religious creeds, epic poems to novels, research articles to emails, the texts we read invite us to connect with the words and thoughts of others. Today, humans aren’t the only ones reading. As large language models (LLMs) permeate our lives, we increasingly lean on them to read on our behalf. AI-as-reader can produce an impressive comparison of Mark Twain’s The Adventures of Huckleberry Finn and Percival Everett’s James. It can locate, summarize, and analyze scores of research papers. Human labor is reduced, but with what consequences? The question is increasingly pressing, given worrisome declines in how much both children and adults are reading of their own volition. Documenting a related trend, my research with Anne Mangen found that 49% of the US university faculty we surveyed were assigning less reading than in the past, with 34% indicating this was because students were ignoring the assignments.But the value of reading far supersedes completing academic or professional tasks. My research on AI and reading probes mental consequences of outsourcing reading, along with benefits from reading ourselves. Both experiments and self-reports indicate diminished cognitive effort and potential deskilling if AI reads for us. When doing our own reading, we build human connections, perhaps leading to empathy. We relax, escape, or peer into the minds of others. Reading encourages us to contemplate whom we want to emulate or what values we might aspire to. Coming-of-age novels (including Huckleberry Finn and James) enable us to vicariously share in – and learn from – the protagonist’s journey. Turning to AI for some reading tasks, some of the time, is a principled choice. However, in our AI-saturated world, it behooves us not to ignore the personal rewards human reading can bring.

    Nick Dorzweiler, Wheaton College - Understanding the Relationship Between Politics and Anxiety

    How do we best understand the relationship between politics and anxiety? Nick Dorzweiler, professor of the practice of political science and women’s and gender studies at Wheaton College, delves into this. Faculty Bio: Nick Dorzweiler joined Wheaton College in 2015, after completing doctoral work at Northwestern University. His research is guided by an overarching interest in the history of the social sciences and its impacts on political life beyond the academy. Nick has published on topics including the politics of popular culture, the history or the social sciences, democratic theory, feminist pedagogy, and the development of Critical Theory in the American academy in outlets such as Perspectives on Politics, Contemporary Political Theory, Polity, Constellations, New Political Science, and The History of the Human Sciences.Nick is a passionate teacher, and has developed courses at Wheaton that span the fields of international relations, political theory, and women’s and gender studies. In each of his classes, Nick seeks to uncover the history of our present in order to encourage his students to think deeply about who we are, how we got here, and where we can go – both as individuals and as members of larger political communities. Transcript: We live, we’re told, in an age of exceptional anxiety – a “polycrisis” of political polarization,economic uncertainty, environmental collapse, and rapid technological change. But this isn’t thefirst time Americans have felt this way. In the late 1930s, the US faced a similarly overwhelmingslate of challenges, from the Great Depression to the rising specter of world war to dizzyingtechnological innovation. My research unearths a provocative but forgotten effort to manage Americans’ collective anxieties during this period of deep social and political uncertainty.In 1939, the influential political scientist Harold D. Lasswell created Human Nature in Action, anNBC radio show that presented itself as an entertaining self-help program on how to managepersonality quirks and get along better with others. Behind the friendly advice, however, was afar more ambitious mission: training citizens to adjust themselves to their anxieties before theycould be expressed in in ways that Lasswell thought were pathological. This included everythingranging from individual expressions of sociopathy to mass revolutionary uprisings.In uncovering this remarkable effort to manage citizens’ mental health, my work explains whyone of the most famous scholars of the twentieth century believed the public needed this programof mass psychotherapy – and why the nation’s largest broadcaster agreed. Yet there is contemporary relevance here, too. Indeed, the propagandistic methods Lasswell felt he needed to use to achieve his objectives suggests we may need new ways of understanding the relationship between politics and anxiety. While Lasswell hoped to create a society free from anxiety, I draw on insights from existential psychiatry and related scholarship in humanistic psychology to argue that a more realistic – and democratic – approach is to nurture an appreciation for certain experiences of anxiety as inevitable yet also meaningful components of living in a world defined by pluralism, freedom, and growth.
