Adam Frank: New Peer-reviewed Studies Change the Conversation on UFOs

For decades, talk of UFOs has thrived on fuzzy photos and personal anecdotes—never the kind of hard data scientists can actually test. But new peer-reviewed studies have changed the conversation, says Adam Frank, a University of Rochester astrophysicist who studies life in the universe and the nature of scientific discovery. Two recent papers, published in reputable astronomy journals, claim to have found evidence of “non-terrestrial artifacts” in astronomical photographs from the 1950s — objects that appear to be  orbiting Earth before the Space Age began. “That’s an extraordinary claim,” Frank says, “and, as Carl Sagan famously said, 'Extraordinary claims require extraordinary proof.' “The good news is that, finally, there’s something associated with UFOs that science can work with.” Led by astronomer Beatriz Villarroel and her VASCO project (Vanishing and Appearing Sources during a Century of Observations), the studies passed the first test of scientific credibility: rigorous peer review. Now, Frank says, comes the harder part — the “call-and-response” that defines real science. “Getting a paper published doesn’t make the claim right,” he explains. “It just means the debate can begin. Other scientists will now dig into the data, test the methods, and try to tear the claim apart. That’s how science works.” Frank is a frequent on-air commentator for live interviews and segments in national media outlets and the author of The Little Book of Aliens (Harper Collins, 2023). He also regularly contributes to written publications, including The Washington Post, The Atlantic, The New York Times, and Scientific American. In 2021 he received the Carl Sagan Medal, which recognizes and honors outstanding communication by an active planetary scientist to the general public. It is awarded to scientists whose efforts have significantly contributed to a public understanding of, and enthusiasm for, planetary science. Connect with him by clicking on his profile. 

Lighting the Night: The History and Meaning of the Jack-o’-Lantern

No Halloween is complete without the warm flicker of a Jack-o’-Lantern glowing from porches and windowsills. But long before it became a symbol of trick-or-treating and fall décor, the carved pumpkin had deep roots in folklore, superstition, and the immigrant experience that shaped North American culture. From Folklore to Flame The story begins in Ireland, where early Jack-o’-Lanterns were not pumpkins at all, but turnips and beets. The tradition sprang from an old Irish folktale about “Stingy Jack,” a clever but dishonest man who tricked the Devil and was doomed to wander the Earth with only a burning coal inside a hollowed-out turnip to light his way. People began carving their own “Jack’s lanterns” to ward off wandering spirits and evil forces during Samhain, the Celtic festival marking the end of the harvest and the beginning of winter. When Irish and Scottish immigrants brought this tradition to North America in the 19th century, they discovered that the native pumpkin—larger, softer, and easier to carve—was the perfect replacement. The transformation from turnip to pumpkin turned a small superstition into a dazzling new folk art. The American Reinvention By the mid-1800s, Jack-o’-Lanterns had become a staple of Halloween celebrations in the United States. Newspapers of the era described “pumpkin lanterns” lighting up autumn gatherings, and by the early 20th century, the smiling (and sometimes sinister) carved pumpkin was the defining symbol of the holiday. Over time, the tradition evolved from scaring away spirits to creating community and creativity. Towns began holding carving contests, families passed down patterns and designs, and pumpkin patches and Halloween festivals turned the once-humble lantern into an essential piece of American seasonal culture. A Symbol Beyond Scares Today, Jack-o’-Lanterns carry layered meanings: they celebrate harvest, creativity, and folklore while keeping a touch of the supernatural alive. In many ways, they embody the blend of ancient myth and modern celebration that defines Halloween itself—where fear meets fun, and the flicker of a candle becomes both decoration and tradition. Whether whimsical or eerie, the glowing face of a Jack-o’-Lantern continues to connect generations to an age-old story about light overcoming darkness—a reminder that even the spookiest traditions began with a spark of human imagination.

UF scientist studies muscle loss in space to benefit astronauts and patients on Earth

Astronauts traveling to Mars will face many challenges, but one of the most serious is muscle loss during long space missions. A new study led by University of Florida researcher Siobhan Malany, Ph.D., sheds light on how human biology changes in microgravity and could help protect astronaut health while also offering hope for patients with muscle-wasting diseases on Earth. Malany, an associate professor in the College of Pharmacy, a member of UF’s Astraeus Space Institute, and director of the in-space Biomanufacturing Innovation Hub, recently published findings showing how muscle cells adapt in space. Her team studied bioengineered three-dimensional muscle tissues derived from biopsy cells from both younger and older individuals and observed how they responded to electrical stimulation in microgravity. These micro-scale tissues called “tissue chips” were given nutrients and electric pulses autonomously in a miniature laboratory the size of a shoe box called a CubeLab.x. A camera system inside the box recorded the rate of muscle contraction. “This research is about more than just space,” Malany said. “By understanding how muscle tissue deteriorates much faster in microgravity, we can uncover new strategies to address muscle loss that occurs naturally with aging and with age-related diseases here on Earth.” Siobhan Malany studies the effects of microgravity on human muscle biology using an automated tissue chip system. View her profile here The study found that younger muscle tissue showed more pronounced changes in mitochondrial pathways — cellular systems that produce energy — than older tissue did when exposed to microgravity. Researchers also discovered that, on Earth, older muscle tissue responds less to electrical stimulation than younger tissue. But in space, the younger tissue showed a noticeable drop in its ability to contract, suggesting that younger muscle may experience a greater change when exposed to the space environment. These insights may help researchers design new treatments to protect muscles in astronauts during long missions, as well as develop therapies for people experiencing age-related muscle loss on Earth. The project was part of UF’s broader efforts to advance space biology. Through the Astraeus Space Institute, UF brings together experts across disciplines, from medicine and pharmacy to engineering and plant science, to address the unique challenges of space exploration. “UF researchers are helping lay the groundwork for humanity’s next giant leap,” Malany said. “It’s exciting to see our work contribute to both the health of astronauts and the lives of patients back home.” UF’s leadership in space biology is strengthened through collaboration with partners including the Kennedy Space Center Consortium and the Center for Science, Technology and Advanced Research in Space), both initiatives bringing together universities in Florida’s high-tech corridor, government agencies and industry leaders. Malany’s work also builds on long-term collaborations with AdventHealth, using donated tissue samples to model age-related muscle changes in space. Her team also works with SpaceTango, a NASA-certified aerospace company, to design the CubeLab that flew to the International Space Station on multiple SpaceX missions. Looking ahead, Malany and her team are developing new ways to study astronaut-derived cells, including both skeletal and heart muscle, generated from blood samples. These “avatars” could help researchers track changes before, during and after space missions, providing an unprecedented window into how microgravity affects the human body. “Now we can study cells from individual astronauts and see how they respond over time,” Malany said. “This helps us understand the risks of long-term spaceflight and also gives us a platform for testing potential treatments for muscle-wasting conditions on Earth.” By using tissue chips, small, bioengineered devices that mimic the structure and function of human organs, scientists in space can gather data more quickly and accurately than with traditional animal studies, potentially accelerating the discovery of therapies for aging-related muscle loss.

Simulations of Exoplanet Formation May Help Inform Search for Extraterrestrial Life

Florida Tech astrophysicist Howard Chen is offering new insights to help aid NASA’s search for life beyond Earth. His latest theoretical work investigates the TRAPPIST-1 planetary system, one of the most widely studied exoplanetary systems in the galaxy. It has captured scientists’ attention for its potential to host water, and thus possibly life, on its planets. Now, he’s offering an explanation for why telescopes have yet to find definitive signs of either. The paper “Born Dry or Born Wet? A Palette of Water Growth Histories in TRAPPIST-1 Analogs and Compact Planetary Systems” was authored by Chen, an assistant professor of space sciences, and researchers from NASA, Johns Hopkins University and Harvard University, was published in The Astrophysical Journal Letters in September. It explores the likelihood that TRAPPIST-1’s three innermost exoplanets contained no water when they formed, despite existing in a zone where water is viable. TRAPPIST-1 is a red dwarf star located about 40 light-years away from us. (One light year is about 6 trillion miles.) It is thought to be about 7.6 billion years old, or 3 billion years older than our Sun. Astronomers are captivated by the TRAPPIST-1 system because its seven known planets are rocky and Earth-like. They also fall within the star’s habitable zone: the distance range from a star at which temperatures are not too hot or cold to support liquid water. Researchers are searching for any evidence of water on these planets, but have yet to detect anything. Some think a lack of gas in the atmosphere is disrupting the light needed to pick up detailed visuals. Others predict water could have escaped the planets’ atmospheres throughout their evolution. Chen and his team, however, decided to research a different theory: that there was no water to begin with because there was no gas to contain it. He would test it not from an observational perspective, but with mathematical modeling of the planets’ initial formation. “You have astronomers who are using telescopes to see what’s out there. I come from a different perspective,” Chen said. “I’m both trying to explain what we’re seeing while trying to make predictions about what we can’t.” The researchers created models that examined the composition and growth of these planets starting when they were as small as one kilometer wide. They simulated how material aggregated during collisions with other celestial objects until they reached their final planetary formations. There are several key factors in collision events that heavily influence a planet’s final composition. Chen’s models incorporated impact delivery, which is the transfer of materials like water and gases during a celestial collision; impact erosion, which refers to the removal of materials in a planet’s atmosphere due to impact; and mantle-atmosphere exchange, which is the transfer of water and gases between a planet’s atmosphere and mantle to maintain its conditions. The team ran hundreds of collision simulations, which returned thousands of different possibilities for how TRAPPIST-1’s planets might have formed. They varied several components, such as the amount of water available to the system, the profile of the initial planet formation environment, the planets’ density profiles and the initial system conditions. For the inner worlds, specifically the first three planets, most of the simulations came back dry. “Whatever we did, we couldn’t get much water in these inner planets,” Chen said. He believes that the main reason the planets couldn’t acquire water is due to the nature of the collision events. Compact planet collisions are higher velocity, so they are more aggressive and energetic, Chen said. This means that instead of acquiring material for a gaseous atmosphere, planets’ atmospheres were completely cleared out by the power of the collisions. With no gas in the atmosphere to contain water, it’s possible that any previously existing water escaped back into space during these collision events. Understanding a planet’s earliest characteristics, its water, air and carbon content, builds the foundation for how they evolve. That way, when researchers identify a planet that seems viable for life at the surface level, they can use Chen’s model to simulate what these distant worlds might be like on the inside, on the surface and in the air. Combining the theoretical context of a planet’s formation with the state in which it was discovered can help researchers – and NASA – make informed, efficient decisions on which planets are worth investigating and when it’s time to move on to the next. If you're interested in connecting with Howard Chen about the search for life beyond Earth, let us help.

Swimming in the deep: MSU research reveals sea lamprey travel patterns in Great Lakes waterways

Why this matters: Invasive sea lampreys prey on most species of large Great Lakes fish such as lake trout, brown trout, lake sturgeon, lake whitefish, ciscoes, burbot, walleye and catfish. These species are crucial to Great Lakes ecosystems and to the region’s fishing industry. Understanding how sea lampreys migrate can inform management and conservation strategies, such as developing methods to catch the invasive fish that don’t involve dams, which reduce river connectivity, or lampricide, a pesticide that some communities and groups prefer not to use. The Great Lakes fishing industry is worth $7 billion and provides 75,000 jobs to the region. Reducing the amount of sea lamprey in waters is crucial for the industry’s well-being and the economic vitality of the Great Lakes. How do you catch an invasive fish that’s solitary, nocturnal and doesn't feed on bait? Researchers in the Michigan State University College of Agriculture and Natural Resources are one step closer to figuring it out. In a study published in the Journal of Experimental Biology and funded by the Great Lakes Fishery Commission, Kandace Griffin, a fisheries and wildlife doctoral student, and Michael Wagner, professor in the MSU Department of Fisheries and Wildlife, found that sea lampreys — a parasitic fish considered an invasive species in the Great Lakes region of the U.S. — follow a clear pattern of staying in the deepest parts of a river. These findings are important for informing sea lamprey management strategies, conservation of fish species native to the Great Lakes and protecting the region’s $7 billion fishing industry and the 75,000 jobs it provides. “We wanted to know how sea lampreys are making their movement decisions when migrating,” Griffin said. “Are they guided by certain environmental cues? Are they moving through areas that are safer? How can we potentially exploit those decisions or maybe manipulate them into going somewhere that they don’t want to go, like pushing them into a trap.” The primary methods used to control sea lamprey are dams that block them from entering waterways and lampricide, a species-specific pesticide that targets lamprey larvae. “Dams create a lot of challenges for conserving river ecosystems: They block all the other fish that are moving up and down in the system. Even though lampricide is proven to be safe and effective, there are communities that are uncomfortable with its use going into the future,” Wagner said. “Figuring out the right way to fish sea lamprey would decrease its population, lower reproduction rates and provide managers with the opportunity to match their control tactics to the community’s needs.” To track lamprey movements, Griffin and Wagner used a method called acoustic telemetry, which involved using sound emitted from a surgically implanted tag to track the movement of 56 sea lampreys in the White River near Whitehall, Michigan. Griffin likened acoustic telemetry to GPS. “There’s a tag that emits sound and has a unique transmission with a unique identification code, so I know exactly which fish is going where,” she said. “The receivers are listening for that sound and then calculating the time it reaches each receiver. We used this information to triangulate the position of the sea lamprey and analyzed it to find out how they’re using the river’s environmental traits to make decisions on where to swim.” Of the 56 lampreys studied, 26 of them (46%), consistently chose the deepest quarter of the river. “For nearly 20 years we have been discovering how sea lampreys migrate along coasts and through rivers. Now, thanks to Kandace’s work, we know where their movement paths come together near a riverbank — the perfect place to install a trap or other fishing device,” Wagner said. “That knowledge can be used to find similar sites across the Great Lakes basin.” Right now, a fishing device designed to catch bottom-swimming, solitary, nonfeeding, nocturnal sea lamprey doesn’t exist. However, Wagner notes there are places around the world — including Indigenous communities in the U.S. — where people have fished migratory lampreys of various species for hundreds of years and could help inform the creation of such a mechanism. “We have recently had a proposal funded to scour the Earth in search of knowledge, both scientific and traditional, about how to capture migrating lampreys and similar fishes,” Wagner said. “We want to talk with the communities of people who have histories fishing these animals and use this information, along with other data we’ve gathered, to conceive a device that could be used to fish sea lampreys.” Griffin views the new intel on lamprey migration patterns as a way to inform fishing practices to complement some of the existing control methods. “Hopefully, we can use this as a supplemental control method to the use of the barriers or dams,” she said. “We have societal pressure to remove barriers to enhance river connectivity, and some barriers are failing. Open water trapping is another way that we could try to still combat the invasive sea lamprey problem here but also promote river connectivity and other conservation goals for other species.” Wagner shares the same perspective. “When a community, or the Great Lakes Fishery Commission, or the governments of Canada and the U.S. come in and say, ‘We’d really rather be able to control this river with something other than lampricide,’ we want to be able to be able to provide 360-degree solutions that specify where to fish, when to fish and how to fish using fully prototyped and tested equipment,” he said. “We want our science to help solve real-world problems.”

First scientific paper on 3I/ATLAS interstellar object

When the news started to spread on July 1, 2025, about a new object that was spotted from outside our solar system, only the third of its kind ever known, astronomers at Michigan State University — along with a team of international researchers — turned their telescopes to capture data on the new celestial sighting. The team rushed to write a scientific paper on what they know so far about the object, now called 3I/ATLAS, after NASA’s Asteroid Terrestrial-impact Last Alert System, or ATLAS. ATLAS consists of four telescopes — two in Hawaii, one in Chile and one in South Africa — which automatically scans the whole sky several times every night looking for moving objects. MSU’s Darryl Seligman, a member of the scientific team and an assistant professor in the College of Natural Science, took the lead on writing the paper. “I heard something about the object before I went to bed, but we didn’t have a lot of information yet,” Seligman said. “By the time I woke up around 1 a.m., my colleagues, Marco Micheli from the European Space Agency and Davide Farnocchia from NASA’s Jet Propulsion Laboratory, were emailing me that this was likely for real. I started sending messages telling everyone to turn their telescopes to look at this object and started writing the paper to document what we know to date. We have data coming in from across the globe about this object.” The discovery Larry Denneau, a member of the ATLAS team reviewed and submitted the observations from the European Southern Observatory's Very Large Telescope in Chile shortly after it was observed on the night of July 1. Denneau said that he was cautiously excited. “We have had false alarms in the past about interesting objects, so we know not to get too excited on the first day. But the incoming observations were all consistent, and late that night it looked like we had the real thing. “It is especially gratifying that we found it in the Milky Way in the direction of the galactic center, which is a very challenging place to survey for asteroids because of all the stars in the background,” Denneau said. “Most other surveys don't look there.” John Tonry, another member of ATLAS and professor at the University of Hawaii, was instrumental in design and construction of ATLAS, the survey that discovered 3I. Tonry said, “It's really gratifying every time our hard work surveying the sky discovers something new, and this comet that has been traveling for millions of years from another star system is particularly interesting.” Once 3I/ATLAS was confirmed, Seligman and Karen Meech, faculty chair for the Institute for Astronomy at the University of Hawaii, both managed the communications flow and worked on getting the data pulled together for submitting the paper. “Once 3I/ATLAS was identified as likely interstellar, we mobilized rapidly,” Meech said. “We activated observing time on major facilities like the Southern Astrophysical Research Telescope and the Gemini Observatory to capture early, high-quality data and build a foundation for detailed follow-up studies.” After confirmation of the interstellar object, institutions from around the world began sharing information about 3I/ATLAS with Seligman. What scientists know about 3I/ATLAS so far Though data is pouring in about the discovery, it’s still so far away from Earth, which leaves many unanswered questions. Here’s what the scientific team knows at this point: It is only the third interstellar (meaning from outside our solar system) object to be detected passing through our solar system. It’s potentially giving off gas like other comets do, but that needs to be confirmed. It’s moving really fast at 60 kilometers per second, or 134,000 miles per hour, relative to the sun. It’s on an orbital path that is shaped like a boomerang or hyperbola. It’s very bright. It’s on a path that will leave our solar system and not return, but scientists will be able to study it for several months before it leaves. The James Webb Space Telescope and the Hubble Space Telescope are expected to reveal more information about its size, composition, spin and how it reacts to being heated over the next few months. “We have these images of 3I/ATLAS where it’s not entirely clear and it looks fuzzier than the other stars in the same image,” said James Wray, a professor at Georgia Tech. “But the object is pretty far away and, so, we just don’t know.” Seligman and his team are specifically interested in 3I/ATLAS’s brightness because it informs us about the evolution of the coma, a cloud of dust and gas. They’ve been tracking it to see if it has been changing over time as the object moves and turns in space. They also want to monitor for sudden outburst events in which the object gets much brighter. “3I/ATLAS likely contains ices, especially below the surface, and those ices may start to activate as it nears the sun,” Seligman said. “But until we detect specific gas emissions, like H₂O, CO or CO₂, we can’t say for sure what kinds of ice or how much are there.” The discovery of 3I/ATLAS is just the beginning. For Tessa Frincke, who came to MSU in late June to begin her career as a doctoral student with Seligman, having the opportunity to analyze data from 3I/ATLAS to predict its future path could lead to her publishing a scientific paper of her own. “I’ve had to learn a lot quickly, and I was shocked at how many people were involved,” said Frincke. “Discoveries like this have a domino effect that inspires novel engineering and mission planning.” For Atsuhiro Yaginuma, a fourth-year undergraduate student on Seligman’s team, this discovery has inspired him to apply his current research to see if it is possible to launch a spacecraft from Earth to get it within hundreds of miles or kilometers to 3I/ATLAS to capture some images and learn more about the object. “The closest approach to Earth will be in December,” said Yaginuma. “It would require a lot of fuel and a lot of rapid mobilization from people here on Earth. But getting close to an interstellar object could be a once-in-a-lifetime opportunity.” “We can’t continue to do this research and experiment with new ideas from Frincke and Yaginuma without federal funding,” said Seligman, who also is a postdoctoral fellow of the National Science Foundation. Seligman and Aster Taylor, who is a former student of Seligman’s and now a doctoral candidate in astronomy and astrophysics and a 2023 Fannie and John Hertz Foundation Fellow, wrote the following: “At a critical moment, given the current congressional discussions on science funding, 3I/ATLAS also reminds us of the broader impact of astronomical research. An example like 3I is particularly important to astronomy — as a science, we are supported almost entirely by government and philanthropic funding. The fact that this science is not funded by commercial enterprise indicates that our field does not provide a financial return on investment, but instead responds to the public’s curiosity about the deep questions of the universe: Where did we come from? Are we alone? What else is out there? The curiosity of the public, as expressed by the will of the U.S. Congress and made manifest in the federal budget, is the reason that astronomy exists.” In addition to MSU, contributors to this research and paper include European Space Agency Near-Earth Objects Coordination Centre (Italy), NASA Jet Propulsion Laboratory/Caltech (USA), University of Hawaii (USA), Auburn University (USA), Universidad de Alicante (Spain), Universitat de Barcelona (Spain), European Southern Observatory (Germany), Villanova University (USA), Lowell Observatory (USA), University of Maryland (USA), Las Cumbres Observatory (USA), University of Belgrade (Serbia), Politecnico di Milano (Italy), University of Michigan (USA), University of Western Ontario (Canada), Georgia Institute of Technology (USA), Universidad Diego Portales, Santiago (Chile) and Boston University (USA).

The Sky’s the Limit: Researching surface impacts to improve the durability of aircraft

Associate professor Ibrahim Guven, Ph.D. from the Department of Mechanical and Nuclear Engineering is conducting a research project funded by the Department of Defense (DoD) that explores building aircraft for military purposes and civilian transportation that can travel more than five times the speed of sound. Guven’s role in this project is to consider the durability of aircraft surfaces against elements such as rain, ice, and debris. His research group is composed of Ph.D. students who assist with the study and has collaborated with other institutions, including the University of Minnesota, Stevens Institute of Technology and the University of Maryland. Why did you get involved with this research project? The intersection of need and our interests decides what we research. I’m interested in physics and have been working on methods to strengthen aircraft exteriors against the elements for 12 years. We started with looking at sand particle impact damage, and then we graduated from that to studying raindrop impact because that’s a more challenging problem. Sand impact is not as challenging in terms of physics. A liquid and a solid behave differently under impact conditions. The shape of the raindrop changes prior to the impact due to the shock layer ahead of the aircraft. Researching this impact requires simulating the raindrop-shock layer interaction that gives us the shape of the droplet at the time of contact with the aircraft surface. Unlike with sand, analyzing raindrop impact starts at that point, which requires accurate modeling of the pressure being applied. As the aerospace community achieves faster speeds, there’s a need to understand what will affect a flight’s safety and the aircraft’s structural integrity. That need is what I’m helping to fulfill. Were there any challenges you and your research group faced while working on this study? How did you overcome them? Finding data was hard. I’m a computational scientist, meaning I implement mathematical differential equations that govern physics to write computer code that predicts how something will behave. My experiments are virtual, so to ensure that my models work well, I need experimental data for validation. However, conducting experiments on this problem is extremely challenging. That’s the roadblock. Currently, we refer to data from the seventies and eighties. Beyond that, this kind of information is not available. We are working to generate data that my computational methods need for their validation. An example is the nylon bead impact experiment. Some researchers found that if you shoot a nylon bead at a target, it leads to damage similar to that from a raindrop of the same size. It is much easier and cheaper to shoot nylon beads compared to the experiments involving raindrops. However, this similarity vanishes as we go into higher velocities. How do you typically gather data for a project of this nature? We are working with a laboratory under the U.S. Navy. They can accelerate specimens to relevant speeds, meaning they can shoot them into the air at the desired velocity. A colleague at Stevens Institute of Technology also came up with a droplet levitator. He uses acoustic waves emitted by tiny speakers to play a certain sound at a certain frequency to create enough air pressure to suspend droplets midair. To an untrained eye, it looks like magic. They levitate droplets and use a railgun to shoot our samples at the droplets. Our samples hitting the droplets are stand-ins for the aircraft surface material. Once this is done successfully, they shoot a sample with high-speed cameras that can take ten million frames per second. As a result, we get a good, high-fidelity picture of this impact event. That is the type of data I’m seeking, and this is how I get it from my collaborators. What was your overall experience working with the students in your research group? I like to think it was positive. I try to be a nice advisor and give them space to explore, fail, and bring their own ideas. Even if I feel like we’re at a dead-end, I step back and let them figure it out. My role is to help them grow. Teach them, train them and help them along the way. That’s the experience. Did you notice any personal changes in your students during this project? Yeah, I have. When they’re just out of their undergraduate programs, confidence is lacking sometimes. You see them become more sure of themselves as they learn more and more. Often, regardless of whether English is their native language or not, writing is a big issue for every student. How one presents ideas in written form is a persistent problem in engineering. I see the most growth in that area. Again, an advisor has to be a guide and also have patience. Eventually, after working on multiple paper drafts, I can see tremendous improvement. You must allow them to see their shortcomings. It’s important to work with students to refine how they frame a problem, explain it to a wide audience in concise terms, and use neutral language without leading them to certain conclusions. Why do you think that this research is important? Somebody has to do it, right? I believe that I’m the right person because of my background. Personally, I think if this research makes for safer travel conditions, and if I have something to offer, then why not? If we can accurately simulate what happens in these conditions, we can use our methods to test out designs for damage mitigation. For example, we can perform simulations with different surface materials for the aircraft to see if using a different material or layered coating system leads to less damage. In a bigger picture, we’re working on a very narrow problem in our field, but we don’t know how useful that’s going to be in 10, 15 or 30 years from now. Whatever we study and put out there in terms of publications, it may help some other researcher in a different context many years later. This could be space research, modeling an atmosphere on a different planet, or something that is related to our bodies. There are parts of physics in this problem that do not necessarily only apply to high-speed flight. It could be many different things. One has to understand that what is studied may seem obscure today, but because the universe is more or less governed by the same physics, everything should be put in a theoretical framework, done right and shared with the community. People may learn things that could become relevant in the future. It’s not uncommon. What is another subject that you plan to study? The next natural step is coming up with strategies to mitigate damage in these scenarios. If avoiding a risk is not an option, can we actually come up with a solution? We have to determine how to modify an aircraft’s design to prevent a catastrophe. Another extension of my research would be to examine the landing of spacecraft on dusty planetary bodies. During landing on Earth, aircraft approach and reach the ground very smoothly. On the other hand, a spacecraft comes down slowly and needs a lot of reverse propulsion for a soft landing. As it does, it kicks up a large amount of dust, which blows back and hits the spacecraft. Taking into account the damage that occurs due to particle impact is a direct connection to my work. This again is an open area, and because we have ambitions to have a permanent presence on dusty places like the moon and Mars, we have to nail down the concept of landing safely. That is where my research could help.

If you’re experiencing health issues, don’t rely on blogs (even snappy ones)—rely on a qualified medical professional. Fall is here. Kids are back in class, pumpkin spice is back in mugs, and—like clockwork—news headlines are back stirring fear and doubt. This season, RFK Jr. is making noise about vaccines, throwing science under the school bus, and leaving some older Canadians wondering: Who should I trust—politics or science? Spoiler: if you’re betting on politics to keep you healthy, you might as well ask your neighbour’s cat for medical advice. So, let’s get back to basics: what shots you really need, why the science is solid, why politics muddies the waters, and how you can be your own best health advocate. Oh, and because you know me—I’ll sprinkle in a few “if only” vaccines we all wish existed. Science vs. Politics: Who Wins? Science: Vaccines work. They reduce severe illness, save millions of lives, and prevent outbreaks of diseases we thought we’d left in history books. COVID-19 vaccines alone are credited with saving over 1.4 million lives in Europe since 2020. Vaccines aren’t some modern fad cooked up in a lab—they’ve been saving lives since 1796, when English doctor Edward Jenner made a discovery that led to the first smallpox vaccines, which at the time was one of the deadliest diseases on earth. Fast forward to today, and the results speak for themselves. Data from the CDC shows that vaccines have slashed major diseases in the U.S. and Canada to the point where polio and smallpox haven’t been seen in decades—down from tens of thousands of cases every year in the 20th century. Even measles, which has made a resurgence due to rising vaccine skepticism, is still nowhere near the half-million infections Americans used to see annually. Thanks to vaccines, measles, pertussis, mumps, and rubella are now more likely to show up in a history book—or on a pub trivia night—than in your family doctor’s office. Over a century of data shows that vaccines don’t just work—they’ve rewritten medical history. A landmark CDC study published in JAMA by researchers Sandra W. Roush (MT, MPH) and Trudy V. Murphy, MD, with Centers for Disease Control and Prevention, Atlanta, Georgia did a major study comparing disease rates before and after vaccines became widespread.  The results were jaw-dropping: Cases of diphtheria, mumps, pertussis, and tetanus dropped by more than 92%, and deaths by more than 99%. Endemic polio, measles, and rubella have been eliminated in the U.S and Canada. Smallpox is gone from the globe. Even newer vaccines introduced since 1980—like those for hepatitis A, hepatitis B, Hib, and chickenpox—cut cases and deaths by 80% or more. The evidence found by the CDC study was so overwhelming that the authors called vaccines “among the greatest achievements of biomedical science and public health” (Source: JAMA, 2007) The number of cases of most vaccine-preventable diseases is at an all-time low; hospitalizations and deaths have also shown striking decreases. Think about it. When was the last time someone at your dinner table worried about catching smallpox? Enter RFK Jr., stage left. He has wasted no time since his appointment as US Secretary of Health & Human Services to undermine confidence in the public health system.  His recent moves—firing the CDC director, cutting mRNA funding (even for cancer vaccines!), and gutting expert panels—are sowing doubt faster than a Toronto raccoon opening a green bin. Even Dr. Martin Makary, Commissioner of Food and Drugs for the U.S. Food and Drug Administration (FDA), recently chimed in with an opinion piece published last week in  The Wall Street Journal. His take? Vaccines should mostly be reserved for high-risk groups, healthy people don’t really need them, and maybe we should start running more placebo trials “just to be sure.” That sounds reasonable until you realize it’s the same playbook RFK Jr. uses: shrink access, shift the burden of proof endlessly, and treat vaccines like optional extras. When Politics Drowns Out Science, Seniors Pay the Highest Price When politics drowns out science, we pay the highest price. Because the truth is: our immune systems age just like our knees do—creaky and slower to respond. Vaccines aren’t optional; they’re essential. Demanding new placebo trials for vaccines we already know work is like asking a baker to prove yeast makes bread rise every single year. And framing vaccines as “only for the sick” ignores the basic truth: when coverage falls, outbreaks rise. Period. Vaccines for Canadian Adults & Seniors (Source: Health Canada) Vaccines aren’t just for kids—they’re part of healthy aging, too. Health Canada has issued clear guidelines on which shots adults and seniors should have on their radar, from flu and pneumonia to shingles and RSV. Think of it as a maintenance schedule for your immune system. That said, every person’s health history is unique, so always check with your doctor or healthcare provider before rolling up your sleeve. Flu shot (Seasonal Influenza Vaccine) – Protects against flu strains that mutate yearly (PHAC – Influenza Vaccine). Everyone should receive it annually; seniors may be eligible for a high-dose version. Pneumococcal (Pneu-C-20) – Shields you from pneumonia, bloodstream infections, and meningitis (PHAC – Pneumococcal Vaccine). One dose at 65+. Shingles (Recombinant Zoster Vaccine – RZV) – Stops the chickenpox virus (that never left your body) from staging a painful comeback tour (PHAC – Shingles Vaccine Guidance)—two doses, starting at age 50. Tdap (Tetanus, Diphtheria, Pertussis Vaccine) – Protects against lockjaw, a throat infection, and whooping cough (PHAC – Tdap Vaccine). One-time booster, then Tdap every 10 years. Polio (Inactivated Poliovirus Vaccine – IPV) – Keeps polio from making a comeback (PHAC – Polio Vaccine). Needed if you missed doses or travel to outbreak zones. RSV (Respiratory Syncytial Virus Vaccine) – Prevents serious lung infections in older adults (Health Canada – RSV Vaccine Information). Recommended for ages 75+ or in long-term care. MMR (Measles, Mumps, Rubella Vaccine) – Blocks childhood triple threats (PHAC – MMR Vaccine). One dose if born after 1970 and not immune. Varicella (Chickenpox Vaccine) – For those who have never had chickenpox (PHAC – Varicella Vaccine). Two doses under age 50; For those over 50, the shingles vaccine is recommended. The Vaccines We Wish Existed Because let’s face it: medicine has cured smallpox, but not small talk. RV – Rectitious Vision Correction: For correcting poor attitudes and selective hearing in spouses. FOMOVAX: Stops the green-eyed monster when your friends are on a Caribbean cruise and you’re at Costco. TechTonic: For when Zoom won’t unmute and your iPad keeps asking for your “Apple ID you made in 2009.” EarPeace: Selective hearing—blocks whining, amplifies compliments. WineNot: The Thanksgiving booster that helps you tolerate in-laws, politics talk, and Uncle Bob’s gravy complaints. MemoryMap: Protects against the “where did I put my glasses?” epidemic. Spoiler: they’re on your head. If only. Until then, we’ll have to stick with flu and shingles shots. Screening Schedule: The Other Half of the Health Checklist Keeping your health on track sometimes feels like managing a full-time maintenance schedule. After all, the human body has more moving parts than a Canadian Tire catalogue—so of course things need regular tune-ups. If vaccines are like scheduled oil changes for your immune system, screenings are more like the regular safety inspections—checking the brakes, the lights, and making sure nothing rattles when it shouldn’t. Our bodies have a knack for keeping secrets until it’s too late, which is why Health Canada and national guidelines recommend routine checks for cancer, heart health, bone strength, and more. Here’s the recommended Health Canada guidelines—your doctor may adjust based on your risk.: Cervical (Pap test): Every 3 years, ages 25–69 (CTFPHC – Cervical Cancer Guideline). Breast (Mammogram): Every 2–3 years, ages 50–74 (CTFPHC – Breast Cancer Screening). Colorectal (Colonoscopy or FIT test): Every 2 years (FIT) or 10 years (colonoscopy), ages 50–74 (CTFPHC – Colorectal Cancer Screening). Prostate (PSA test): Discuss with your doctor around age 50 (CTFPHC – Prostate Cancer Guideline). Lung Cancer Screening: For current/former heavy smokers, typically ages 55–74 (Canadian Partnership Against Cancer – Lung Cancer Screening). Bone Density (DXA scan): At 65+ or earlier if at risk (Osteoporosis Canada – BMD Testing). Blood Pressure & Cholesterol: Annual or as needed (Hypertension Canada Guidelines). Diabetes (A1C test): Every 3 years starting at 40 (Diabetes Canada – Clinical Guidelines). Your Fall Holistic Health Checklist Still with me?  Here's a checklist that I personally follow as a seasonal tune-up—part vaccines, part screenings, part lifestyle hacks. It’s not about chasing perfection; it’s about making sure you’ve got the energy to keep doing what you love (and maybe even outpace the grandkids). Whether you’re just easing into retirement, solidly in the groove, or rocking your seventies with style, these age-by-age tips will help you stay sharp, strong, and one step ahead of sneaky health surprises. Pre-Retirees (55–64) • Annual flu shot • Covid-19 shot • Start shingles series (50+) • Tdap booster if due • Immunization catch-up (MMR, polio, varicella) • Screenings: Pap, mammogram, colon, bloodwork • Exercise, hydrate, and learn to say no—yes, that’s preventive care too. Post-Retirees (65+) • Annual flu shot (high-dose if offered) • Covid-19 shot • Pneumococcal vaccine • RSV vaccine (75+ or communal living) • Shingles vaccine if not done • Screenings: colon, prostate, bone density, cholesterol, diabetes • Keep bones strong: vitamin D, weight training, and occasionally lifting grandkids count. Active Retirees (70+) • All of the above • Review meds and fall-prevention strategies • Stay social—book clubs, golf leagues, dance classes. Loneliness is a silent epidemic. • Advocate for friends, spouses, and grandkids—because being the family health quarterback matters. Your Best Shot: Be Your Own (and Your Community’s) Advocate Vaccines and screenings are only half the story—the other half is using your voice. Seniors have enormous influence, and when you speak up, policymakers listen. Here are a few ways to make sure your concerns don’t get lost in the shuffle: Start local. Write a short letter or email to your Member of Parliament, MPP, or Mayor. Personal stories are more powerful than statistics—tell them why vaccines, screenings, and health services matter to you and your community. Pick up the phone. Constituency offices actually log every call, so even a five-minute conversation with a staffer goes on record. Think of it as Yelp for public policy. Go public. A letter to the editor in your local paper or a well-placed comment at a town hall gets noticed by decision-makers. Be persistent (but polite). Politics moves slowly, but steady nudges add up. You don’t need to storm Parliament—just keep knocking on the door. You’ve spent a lifetime paying taxes, raising families, and building communities—you’ve earned the right to be heard. And let’s be real: nobody wants to mess with a senior who’s got a phone, an email list, and time to follow up. This fall, don’t let politics steal your peace of mind. Don’t let headlines plant seeds of doubt. Vaccines and screenings aren’t about fear—they’re about freedom: freedom to keep moving, keep laughing, keep living the “Hip, Fit & Financially Free” life you deserve. And until they invent the "WineNot" booster or the "MemoryMap" shot, your best defence is still the good old-fashioned flu, shingles, and pneumonia vaccines—plus the screening tests that catch sneaky stuff early. So roll up your sleeve. Book that screening. Be your own health advocate. And while you’re at it, sign your spouse up for the RV shot—because an attitude adjustment should absolutely be a household vaccine. Stay healthy. Don't Retire - Rewire!

MSU team develops scalable climate solutions for agricultural carbon markets

Why this matters: Builds trust in carbon markets. This science-based baseline system dramatically improves accuracy, helping ensure carbon credits are credible and truly reflect climate benefits. Enables real climate impact by accounting for both soil carbon and nitrous oxide emissions, the approach delivers a full, net climate assessment. Scales across millions of acres. Tested on 46 million hectares in 12 Midwest states, this approach is ready for large-scale adoption, helping farmers transition to regenerative practices with confidence and clarity. New research from Michigan State University, led by agricultural systems scientist Bruno Basso, addresses a major problem in agricultural carbon markets: how to set an accurate starting point, or “baseline,” for measuring climate benefits. Most current systems use fixed baselines that don’t account for the soil carbon changes and emissions that would occur if business-as-usual practices were maintained on fields. Such inaccuracies can distort carbon credit calculations and undermine market trust. “The choice of baseline can dramatically influence carbon credit generation; if the model is inaccurate, too many or too few credits may be issued, calling market legitimacy into question,” said Basso, a John A. Hannah Distinguished Professor in the Department of Earth and Environmental Sciences, the Department of Plant, Soil and Microbial Sciences and the W.K. Kellogg Biological Station at MSU. “Our dynamic baseline approach provides flexible scenarios that capture the comparative climate impacts of soil organic carbon, or SOC, sequestration and nitrous oxide emissions from business-as-usual practices and the new regenerative system.” The research, published in the journal Scientific Reports, covers 46 million hectares of cropland across the U.S. Midwest, provides carbon market stakeholders with a scalable, scientifically robust crediting framework. It offers both the investment-grade credibility and operational simplicity needed to expand regenerative agriculture. Regenerative agriculture and carbon markets Regenerative agriculture includes practices like cover cropping, reduced or no tillage, diversified rotations, adaptive grazing and agroforestry. These methods restore soil health, enhance biodiversity, increase system resilience and help mitigate climate change by building SOC and reducing greenhouse gas emissions. Carbon markets offer a promising financial mechanism to accelerate regenerative transitions. By compensating farmers for verified climate benefits, they can act as either offset markets (for external buyers) or inset markets (within agricultural supply chains). However, the integrity of these markets hinges on reliable, science-based measurement, reporting and verification systems that integrate modeling, field data and remote sensing. A breakthrough multi-model ensemble approach To overcome limitations in traditional modeling, the MSU scientists and colleagues from different institutions in the U.S. and Europe deployed a multi-model ensemble, or MME, framework, using eight validated crop and biogeochemical models across 40,000 locations in 934 counties spanning 12 Midwestern states. The MME avoids model selection bias, lowering uncertainty in soil carbon predictions from 99% (with single models) to just 36% (with the MME). “This is a game changer for carbon markets,” said Basso. “It delivers a level of accuracy and scalability — from individual fields to entire regions — that current systems lack.” The MME platform also enables the creation of precalculated, practice-based dynamic baselines, reducing the burden of data collection and easing participation for producers. Improved mitigation assessments Unlike many approaches that consider only SOC, the MSU lead team’s study evaluates both SOC sequestration and nitrous oxide emissions to determine net climate impact. “This comprehensive assessment ensures that carbon credits represent true climate mitigation,” said Tommaso Tadiello, postdoctoral fellow in MSU’s Department of Earth and Environmental Sciences and co-author of the study. “A practice that increases soil carbon may improve soil health,” added Basso, “but it may not deliver actual climate benefits if it simultaneously increases nitrous oxide emissions. Our method provides a full accounting of the net climate effect.” The research team found that the combination of no-till and cover cropping delivered an average net mitigation of 1.2 metric tons of carbon dioxide-equivalent per hectare annually, potentially abating 16.4 teragrams of carbon dioxide-equivalent across the study area. This research was supported by the Michigan Department of Agriculture and Rural Development, U.S. Department of Energy’s Great Lakes Bioenergy Research Center, National Science Foundation Long-Term Ecological Research, Builders Initiative, The Soil Inventory Project, Generation IM Foundation, Walton Family Foundation, Morgan Stanley Sustainable Solutions Collaborative and MSU AgBioResearch.

Engineering professor develops eco-friendly method of creating semiconductor materials for electronics

A Virginia Commonwealth University researcher has developed an alternative method of producing semiconductor materials that is environmentally friendly. Semiconductors are crucial to modern electronics and displays, but they are constructed from toxic solvents. They also are created at high temperatures and pressures, resulting in both environmental damage and high production costs. The new technique has been introduced by Leah Spangler, Ph.D., assistant professor in the VCU College of Engineering’s Department of Chemical and Life Science Engineering, and Michael Hecht, a professor of chemistry at Princeton University. It demonstrates an alternative method to produce semiconductor materials called quantum dots using proteins at room temperature in water, resulting in a more environmentally friendly synthesis method. “This research uses de novo proteins, which are not taken from natural organisms but instead made by design for specific purposes,” Spangler said. “Therefore, this work shows that protein design can be leveraged to control material properties, creating an exciting new direction to explore for future research.” This work builds on natural examples of proteins creating materials, known as biomineralization. But this is the first example that uses de novo proteins made by design to control the synthesis of quantum dots. The study, “De Novo Proteins Template the Formation of Semiconductor Quantum Dots,” was published in the journal ACS Central Science. The work is related to a recent Department of Defense grant to Spangler to test an eco-friendly approach for separating rare earth elements into a refined final product using de novo proteins.
