Researchers Seek Understanding of Early Life on Earth Following Chilean Expedition
In a discovery that may further our understanding of the early evolution of life on Earth, a research team, including associate professor Andrew Palmer and master’s student Caitlyn Hubric, identified Chile’s deepest and most northern cold seeps—openings in the ocean floor that emit gases and fluids— about 100 miles off the Chilean coast and thousands of feet below the surface. This most terrestrial of discoveries may also yield insights that could benefit future space exploration, Palmer said. Palmer, who runs the astrobiology and chemical ecology lab at Florida Tech, and Hubric, who has studied with him for the last three years, represented the university on Schmidt Ocean Institute’s (SOI) expedition through the Atacama Trench. The trench is a nearly 5-mile-deep oceanic trench in the eastern Pacific Ocean that has remained at the same latitude for the last 150 million years, suggesting an extremely stable and potentially ancient ecosystem. The trench’s seeps, found at a depth of 2,836 meters (9,304 feet), provide chemical energy for deep sea animals living without sunlight, according to SOI. Seeps like this one can help astrobiologists understand how life developed on Earth and how those survival strategies and chemical conditions might sustain life on other planets. Palmer and Hubric were members of the expedition’s microbiology team and were specifically searching for biosignatures. That meant looking out for novel microbes and chemical signatures, like proteins or carbohydrates, which may have existed in the region for millions of years. The benefits of their research extend beyond life on Earth. They could also shape future space exploration. A big part of why they’re investigating water ecosystems is because of the popularity around Saturn’s moon Enceladus and Jupiter’s Europa, Hubric said. She said it’s not a perfect analog, but it’s close enough that they can look for patterns in how life’s chemical processes might operate at these sites. “We hope that some of the questions we answer here find will help us in future endeavors when we do finally go explore the solar system,” Hubric said. Back on campus after the expedition, which ran from May 24 to June 6, they’ve started working to solve those questions by both identifying molecules that guide the search for life and by understanding the limitations of the instruments that can detect metabolites, or early signatures of life, Palmer said. “If [the instruments] can’t successfully identify traces of life on Earth, where we know there’s lots of life, how are they going to be successful in a place where it’s less likely than a needle in a haystack?” Palmer said. “It’s the bigger question of, what do we need to do in order to be successful in the search for life?” For Palmer and Hubric, research has only just begun. They’ll test water and sediment samples and the filtrate that they’ll remove from their water filters and investigate for microbes of interest. Searching for novel metabolisms will be an even more extensive process, Palmer said. “It’s weird doing something where you won’t be able to see the results for weeks or months,” Palmer said. “This is just the beginning.” Looking to know more about the Schmidt Ocean Institute’s (SOI) expedition through the Atacama Trench and Dr. Palmer's research?

Astrobiologist Manasvi Lingam, assistant professor of aerospace, physics and space sciences at Florida Tech, authored a new astrobiology textbook to serve as a resource for the rapidly growing multidisciplinary field. “From Stars to Life: A Quantitative Approach to Astrobiology,” published by Cambridge University Press, is primarily geared toward upper-level undergraduate and graduate students studying astrobiology, Lingam says. Co-authored by astrophysicist Amedeo Balbi (University of Rome), the book’s 15 chapters cover topics from the Big Bang theory to planetary habitability to the future of humankind. The book also includes practice problems that involve modern developments like GenerativeAI (e.g., ChatGPT). Lingam explained how he came up with the new textbook and why it can help shape astrobiology programs like Florida Tech’s. What inspired this textbook? Manasvi Lingam: [Florida Tech] was the first university in the whole world to start an undergraduate astrobiology major. We have a strong connection to the field. But it turns out, every time I teach the subject, I don’t have a textbook to use. I have my first book, which is “Life in the Cosmos,” but it’s 1,100 pages. It’s for graduate students. It’s not going to work for them. Every time I was trying to cobble together resources from different places. My co-author has the same problem except that he’s been teaching [astrobiology] for even longer, for 20 years. He doesn’t have a textbook either. There’s this old saying in English: if you want something done right, do it yourself. We decided, well, might as well just try to write it ourselves. That’s how it came to be. How does this textbook bridge the gap between introductory readings and graduate-level material? ML: Right now, there’s pretty much only one class of textbooks for astrobiology, and those are written for freshman- or sophomore-level undergraduates. There’s this emphasis on a broad overview but at an extremely qualitative level and sometimes offering somewhat weak explanations for various specific phenomena, such as, “Why did Mars lose its atmosphere? It just got eroded over time.” These kinds of limitations. Graduate literature is very specialized, oriented towards whatever subfield one is studying in astrobiology. You can have a whole book on the origin of life. You can have a whole book on just Mars. You can have a whole book on Titan and so on. The aforementioned introductory textbooks that exist are very broad, but they don’t really offer a tool to actually get started doing research in the more specialized field. There was this vital need to bridge the gap. That’s what this book is meant to do. How did you decide what content to include and what not to include? ML: This field begins almost with the Big Bang – the start of the universe – which is when the first elements were formed, including elements that are widespread in life like hydrogen. This tale begins almost with the beginning of the universe. It is a tale that is still ongoing and is going to unfold for trillions of years into the future. But, there was so much material to include in principle. We had to be quite selective about what topics to include. There are a number of courses that are taught around the world on this topic. We looked at dozens of them to find the common core within all of them, and then expanded on that core. That’s what constitutes our table of contents. While writing the textbook, how did you grow as a researcher and an educator? ML: There’s this implicit understanding in academia that if you can write something down clearly, and if you can articulate something clearly, that’s when you can really say you understand it. Often you can’t articulate what you need to say coherently and succinctly if it’s something very big. That’s what, of course, astrobiology is. In the process of writing the book as an educator, I think I was really able to see how various domains linked to each other. For instance, modulations of, say, the Earth’s climate that were driven not just by changes on Earth (including life itself!), but also by changes in the sun, by changes in the orbits of other solar system planets, but also phenomena that were taking place hundreds of light years away in the galaxy. You really see that everything is connected – there are hidden links to each other. I think that helped me discover the magic of the universe, so to speak, even more. From a research standpoint, there were some areas that I have not worked in a lot, but by writing this book, I’ve gotten a better understanding of those areas, like, say, Mars, and also certain microbiological and astrophysical aspects as well. I think that has provided new ideas that I hope to explore in the future. What do you want readers to learn throughout the book, and what should they walk away with? ML: What we want to do is build a holistic integrated understanding of different phenomena pertaining to life in the universe, but at a quantitative level, and still retain breadth without sacrificing depth in the process. It won’t necessarily make students ready for research because it’s still primarily an undergrad textbook, but it will give them a comprehensive understanding of how various processes are intertwined with each other. We want people to see the big picture without missing out on the detail, and to appreciate the beauty of life, Earth, the solar system, the Milky Way and the universe. Lingam plans to start teaching from this textbook in Spring 2025. The textbook is available for purchase on Amazon.

Just before the holiday season, as he entered his final month as President of the United States, Joe Biden announced that he would be granting clemency to roughly 1,500 American citizens. The clemency acts, which included sentence commutations for individuals placed on home confinement during the pandemic and pardons for 39 individuals with non-violent offenses, were touted by the administration as the most ever in a single day in modern history. A month later, on January 17, he commuted the sentences of roughly 2,500 individuals convicted of non-violent drug offenses, shattering December's mark and giving him the most pardons and commutations of any president in United States history. The unprecedented size of the actions has been underscored throughout The White House’s press materials and has headlined most subsequent news coverage. But for Anton Robinson, JD, associate professor of law and director of Villanova’s Caritas Clemency Clinic in the Charles Widger School of Law, the importance of the clemency went far beyond the impressive scale. “Acts like these bring much needed awareness to the clemency process, and to the epidemic of excessive sentencing in United States courtrooms,” Professor Robinson said. “At our clinic, we are already having people call to ask about opportunities for pardons and additional support for their cases.” Public perception of presidential acts of clemency can, at times, be marred by partisan divisiveness. To some, these latest acts were overshadowed by President Biden’s earlier pardon of his son, Hunter, and eyes are already on incoming President Trump regarding how he might handle those charged in relation to the January 6 insurrection. Professor Robinson acknowledges that acts like these can cause people to “rightfully question the power that is being used,” but those are the outliers, not the norms, and steer the conversation away from the root purpose of clemency. “People deserve a second chance,” Professor Robinson said. “There’s a tendency for system actors to focus primarily on the crime committed when considering whether a person’s sentence should be cut short. But many are different people today—sometimes decades later—than they were at the time of the crime’s commission. “There is also no shortage of individuals in prison for whom a charge doesn’t tell the whole story. For example, a young person’s involvement in a crime, while sufficient for a legal conviction, might be weighed differently today, given increasing acceptance of scientific research on the portion of the human brain which controls decision-making, impulse control and executive function. Research shows all of that continues to develop well into adulthood.” Determining who fits the criteria for clemency, Professor Robinson says, is not always easy to do. Collecting records of good behavior that illustrate change while in a carceral setting is much more difficult than collecting records of bad behavior. That’s why entities like the Caritas Clemency Clinic, in which Villanova Law students work directly on behalf of such clients under Professor Robinson’s guidance, spend so much time talking to anyone who has had a relationship with the incarcerated person. “What we often find is that despite being incarcerated and having very little given opportunity, these individuals make their own opportunities to build community and rich relationships and try their best to contribute to society in a positive way,” Professor Robinson said. A military veteran who helped church members in poor health perform tasks. A nurse who spearheaded COVID vaccination efforts and natural disaster response. A counselor who helps guide youth away from destructive behavior and involvement with gangs. Those are the types of actions Professor Robinson references, all of which were highlighted specifically in the White House’s fact sheet for President Biden's December acts, just before the words “The United States is a nation of second chances.” “I'm hoping that these large acts of clemency encourage folks to think, ‘Hey, what about my loved one? What about me? I am a completely different person than I was 20 years ago, what can I do to try to secure my freedom and my ability to live the life that I've missed out on?’” Professor Robinson said. “It really is a great opportunity to remind ourselves that people are far better than the worst things that they've ever done, and that we have an opportunity to acknowledge that as a society and to encourage more of this action, both on a federal and state level.”
Secretary Buttigeg makes one of his final DOT stops at CMU's Safety 21
U.S. Secretary of Transportation Pete Buttigieg visited Carnegie Mellon University in one of his final stops as Transportation Secretary. Raj Rajkumar, director of Safety21 and George Westinghouse Professor in the Department of Electrical and Computer Engineering, with Ph.D. candidates Nishad Sahu and Gregory Su, demonstrated research on the safe navigation of autonomous driving systems in designated work zones, leveraging high-definition mapping, computer perception and vehicle connectivity. “The sophistication of the safety work that’s going on goes well beyond any commercially available automated or advanced driver assistance system is really inspiring,” Buttigieg said. “We’ve got to make sure it develops the right way, we’ve got to be cautious about how it’s deployed, but you can tell a lot of thought and, of course, a lot of incredibly sophisticated research is going into that.”
Image Credit: Petrovich9/Getty Images Plus Although time is a set duration of hours, minutes and seconds, the perception of time can vary dramatically based on the individual and especially during times of high stress and uncertainty such as disasters, recessions and most recently the COVID-19 lockdown. For example, ask anyone when a specific event occurred during the pandemic and they are likely to respond with, “That happened three months ago. Or did that happen three years ago?” While there have been studies on the feeling that there is not enough time or experiencing time as moving too slowly, Baylor University sociologists Matthew Andersson, Ph.D., and Paul Froese, Ph.D., investigated this sense of multifaceted time perceptions during the pandemic and their effects on mental well-being. Their findings – using national Gallup data collected in spring 2021 in the middle of the pandemic – were published in the journal Time & Society. “We know from existing research that people often experience time in altered ways whenever disasters strike, and we wanted to see if that was true during the pandemic as well,” Andersson said. The Baylor researchers found that Americans during the pandemic generally reported some degree of feeling rushed while also perceiving multiple types of time distortion involving slowness, quickness and days and weeks blending together. This disorientation also was frequently reported alongside other pandemic-related stressors, including economic strain, working from home, homeschooling a child and severe household conflict. Together, they complicated how people perceive time by disrupting routines and creating experiences of trauma, adding to the decline in mental well-being and an increase in feelings of loneliness. Time disorientation and mental well-being The top three findings of the study all demonstrate the connection between altered time perception and the mental states of an individual. “If time does not seem to be moving ‘normally,’ it is generally related to lower levels of mental well-being, such as increased depressive, anxiety symptoms or a lessened sense of control,” Andersson said. “We think this is because people tend to feel grounded or calm when they feel like time is moving as it should.” Secondly, the researchers found that individuals can often experience these time disorientations in multiple and contradictory ways, which can be related to even lower well-being. “Feeling rushed and feeling that time is slow are kind of opposites, but they are both related to having this sense of multifaceted blending of time,” Froese said. “We can show very clearly how these new stresses that were brought on by the pandemic created heightened senses of disorientation in terms of time.” More importantly, they found these time disorientations were affected by social, familial, physical and work situations, which created lower levels of mental well-being. “Specific forms of stress we were seeing during the pandemic, such as financial hardship, homeschooling, working from home and severe household conflict, all had relationships to experiencing different kinds of time distortions,” said Andersson. This was more evident in younger people “because it [lockdown] probably upended their daily routines in a much more dramatic way than it would have in somebody who's retired,” said Froese. Experience of time The rushed pace of industrialized society existed before the COVID-19 pandemic, but the stressors associated with the pandemic added to the feelings of time being out of control. “Our approach to capturing experiences of time rests on the assumption that individuals relate to time in complex ways,” Froese said. “We found original evidence to suggest that experiences of quickness, being rushed, slowness and indistinct boundaries of days all coincide, and that these multiple disorientations each relate to diminished mental wellbeing, to objective work and family demands, and to widespread exposures to pandemic-related stressors.” The survey was conducted as part of the Baylor Religion Survey, one of the most extensive national surveys of American religious beliefs, values and behaviors that produces unique data concerning religion, health and community in America today. The 2021 data collection by Gallup contained a section devoted to how the pandemic affected Americans’ activities, including how the pandemic changed the emotional lives of Americans.

Saving the world, one yard at a time
University of Delaware professor Doug Tallamy has a simple mission: Encourage people to rid their property of invasive plants and replace them with native ones. One of the ways he's tackling it is through a concept called “Homegrown National Park,” a grassroots initiative he co-founded to offer a simple solution for the biodiversity crisis — the decline of a variety of animals, plants and numerous species. Tallamy, the TA Baker Professor of Agriculture and Natural Resources at the University of Delaware, is trying to encourage everyone to do their part to protect the planet. If invasive plants (which don’t belong in an area and can ultimately harm the ecosystem by taking away essential resources from other plants) grow out of control, then an area loses its biodiversity, the ability for multiple plant and animal species to function at once and create a rich ecosystem. Invasive species are prolific. For example, many invasive plants produce berries, which some birds eat. The birds then spread those seeds around. So, once invasive plants are in an area, they’re hard to get rid of. The idea is to replace them with native plants, which have historically belonged to a region and provide critical habitat for insects, birds and other creatures. It's an uphill climb, but Tallamy persists and is trying to save the world, one yard at a time. “Everybody has a responsibility of doing things that sustain their little piece of the earth, and there are a whole bunch of things one individual can do to help in that regard,” Tallamy said. What’s not so simple, however, is getting the Earth’s 8 billion people (or, at least, anyone with property) to do this. “We are trying to change the culture so that [replacing invasive plants with native ones] becomes the norm, not the exception,” Tallamy said. “We’re not getting rid of lawns. But we don’t need 44 million acres of them. There are now so many people on the planet that natural systems are not functioning the way they need to sustain us.” A snowball effect Much of our current plant culture revolves around colorful, aesthetically pleasing ornamental plants that don’t support the local food web. When they grow out of control, a local yard or larger region loses out on biodiversity. The natural world is all connected. For example, Tallamy said, if we lose pollinators like our native bees that transport pollen between plants, then we also lose most of our plants that produce flowers and fruits. It’s a snowball effect. “If that happens, the energy flow through our terrestrial ecosystems is almost totally disrupted, which means the food webs that support our vertebrate animals, our amphibians, our reptiles, our birds and our mammals would collapse and all those animals would disappear,” Tallamy said. “Without insect decomposers, the creatures that break down dead material, mostly plants, would rot and only bacteria and fungi would endure.” “Homegrown National Park” has generated a lot of buzz for Tallamy, who received recognition for it in October by the Massachusetts Horticultural Society. The MHS awarded Tallamy with its highest honor, the George Robert White Medal of Honor, for eminent service in the field of horticulture. Conservation in action Tallamy’s quest to “change the culture” on planting can be witnessed in the fall at UD. On a warm October afternoon, he and a group of students from the Introduction to Insect and Wildlife Field Studies (ENWC 165) course trudged out to UD Wetlands to curtail some pesky invasive plants native to Asia. Equipped with clippers, loppers and handsaws, they walked behind Worrilow Hall, part of the College of Agriculture and Natural Resources’ 350-acre campus, which includes the UD Wetlands, an area that was formerly a dairy cow pasture but transformed into wetlands in 2008 because pollution from the farm was reaching the local watershed. The wetlands were created because wetlands, by design, absorb nitrogen from runoff before it goes into waterways. They then release it as a gas into the atmosphere. But the UD Wetlands repeatedly deal with pesky invasive plants such as Porcelain-berry and Chinese elm. Over the years, UD students have stymied the species from overtaking the area. “See this? This is a good guy,” said Tallamy to the students as he held up a fallen branch. “You just want to get the Porcelain-berry off of it. They’ll grow back very well. But we want to nip [the Porcelain-berry] in the bud.” Taylor Kelly, a senior wildlife ecology and conservation major who took part in the invasive species removal, said Tallamy has helped her better understand the interconnectedness of various ecosystems. “Native plants provide so much value to our local pollinators, which add value to our local birds because they feed on pollinators, seeds, fruit and trees,” Kelly said. When native plants are in their natural environment, she added, it is a beautiful thing to see. Gardening with intention Tallamy, who began his teaching career at the University of Delaware in 1982, has published numerous research papers about entomology and written three books about native plants, insects and ecosystems, with a fourth book soon to come out. Lately, much of his career has revolved around public outreach. He often lectures across the country about native plants and their ecosystem value and is regularly quoted in outlets like The New York Times, The Washington Post and Natural History Magazine. “Dr. Tallamy is a rare scientist that is able to explain his work to everyone,” said Jake Bowman, UD professor of wildlife ecology and chair of the Department of Entomology and Wildlife Ecology. “His passion for the importance of native plants has driven a major shift in thinking.” Years ago, when Tallamy first set out to spread his messages about native plants, he anticipated a lot of pushback from horticulture enthusiasts who he thought might be resentful about being told how to choose their plants. Instead, Tallamy found that many actually embraced his ideas, including Delaware’s own Master Gardeners, a group of about 300 volunteer educators trained by UD Cooperative Extension. Among his supporters are Delaware Master Gardeners Karen Kollias, Brent Marsh and Judy Pfister, who each praised Tallamy for the impact he has had on how they garden. Kollias now “gardens with intention”— not for herself or her neighbors, but for the environment. “I was a gardener before,” she said. “Now I consider myself an ecological gardener.” After Marsh received a copy of Tallamy’s 2007 book, Bringing Nature Home, which talks about the link between native plants and native wildlife, Marsh became a Master Gardener and began planting native species in his Georgetown lawn. Today, native plants such as woodland sunflowers and oak trees adorn Marsh’s yard, and he is grateful for the value of native plants that he learned through Tallamy’s book. “Someday, maybe 20 years from now when I’m 100 years old, somebody's going to buy my house and they’re going to say, ‘Who planted all these oak trees?!’” Marsh chuckled. “Doug Tallamy changed my life.” As Tallamy has sought to simplify scientific knowledge with the general public, Pfister has utilized Tallamy’s approach to do the same. “He has a way of just making the whole thing a big circle, tying the need for a plant back to the need for a bird back to the need for a tree,” she said. Tallamy, who has been delighted by the fervor ignited by his native plants teachings, said the future of the Earth and its diverse ecosystems will in large part depend on how people treat their yards. “In the past, we asked our landscapes to do one thing, and that was, be pretty,” Tallamy said. “Now we have to ask them to do two things: be pretty and ecologically functional. That's the horticultural challenge of today.” But it’s one Tallamy believes can be achieved. Sometimes, he wishes he could speak to his 10-year-old self and tell the young boy to dig another pond for the toads to colonize. Restore. Conserve. Focus on keeping nature’s ecosystems intact, he would say. “We have to do both,” Tallamy said. “Yes, we have to conserve what’s out there, but we have to get in the mindset that we can really put a lot of it back.” Tallamy and Homegrown National Park co-founder Michelle Alfandari have created a database for people to type in their zip code and discover which native plants are best for their area.
Villanova Professor Investigates Impacts of Hurricanes on Florida Coast
In October 2024, during the height of hurricane season, Hurricanes Milton and Helene swept across the southeastern United States. Their impact on Florida was severe, with damages totaling tens of billions of dollars. While communities in affected states continue to rebuild, a team of researchers mobilized to assess the damage caused in the hopes of better understanding the impacts of hurricane activity in the future. Jonathan Hubler, PhD, assistant professor of civil and environmental engineering at Villanova University, along with Villanova civil engineering graduate student Sarah Burghardt, traveled to Florida with a joint team from the Nearshore Extreme Events Reconnaissance (NEER) Association and the Geotechnical Extreme Events Reconnaissance (GEER) Association to investigate the immediate aftereffects of Hurricanes Milton and Helene. The National Science Foundation-sponsored trip gathered natural hazards research experts and practitioners from across the country, who quickly jumped at the opportunity to examine the impacts of two tropical storms that occurred in quick succession of each other. A few main areas of study were identified by the team so they could hit the ground running once they touched down in Florida. The researchers wanted to focus primarily on the effects of storm surge, waves, sediment erosion and deposition, and debris transport and accumulation from both hurricanes through pre-storm, during-storm, and post-storm data collection. Over 750 miles were covered across just a few days as data was surveyed and collected from Cedar Key, Horseshoe Beach, Venice, Port Charlotte, Port St. Lucie, Vero Beach and other coastal towns. “This was a unique opportunity for our team of scientists because our team collected data before the storms so we will be able to analyze the direct impacts of the storms utilizing the post-storm data that we collected,” said Dr. Hubler. “Although the destruction was difficult to witness firsthand, we are hopeful that our findings will help to mitigate the impact of these major storms in the future.” The data set collected from these storm sites is expected to improve the understanding, prediction, and mitigation of erosion as well as assess the performance of different shoreline protection systems during severe tropical storm events. Findings from the trip will be shared publicly through the NSF’s Natural Hazards Engineering Research Infrastructure (NHERI) DesignSafe-CI, a nationwide network tailored for data sharing among the natural hazards engineering research community. Local Florida communities will also be notified of relevant findings to increase awareness and understanding of risk assessments when preparing for tropical storm events. “It was a productive few days spent in Florida as we collected a significant amount of data and covered a lot of ground in a short span of time. I’m grateful to have been included on this research team and that I had the chance to bring one of my students along. This real-world experience in the field will help further her learning as she completes her studies,” said Dr. Hubler. Dr. Hubler traveled with the NEER and GEER team again in November for another data collection effort. Although the 2024 hurricane season has come to a close, researchers like Dr. Hubler continue to study their impact year-round to discover new mitigation strategies for next year’s season.
