Robotics help solve deep Sea Mysteries
UD's College of Earth, Ocean and Environment uses robotics currently operated by the National Deep Submergence Facility (NDSF) to study the depths of the ocean. These expeditions ranged from the East Pacific Rise to the Mid-Atlantic Ridge. The vehicles include the Human Occupied Vehicle (HOV) Alvin, the Remotely Operated Vehicle (ROV) Jason and the Autonomous Underwater Vehicle (AUV) Sentry. What it is: A CTD (Conductivity, Temperature, Depth) instrument is a key oceanography tool that collects deep-water samples using remotely triggered Niskin bottles at specific depths. How it helps: These measurements help scientists understand ocean processes, including carbon cycling and life systems, which are essential to understanding Earth’s overall functioning.

One year after his pioneering flight aboard Blue Origin’s New Shepard rocket, University of Florida space biologist Rob Ferl, Ph.D., is still processing what it meant — not just for his career, but for science itself. “What stands out the most is just the overwhelming gratitude,” Ferl said. “It was such an amazing opportunity for a scientist to go to space and actually do science.” Ferl, a professor in UF’s Horticultural Sciences Department, Director of the Astraeus Space Institute, and Assistant Vice President of Research, became one of the first space biologists to fly alongside his own experiment — a moment that marked a new era in researcher-led missions. His suborbital journey provided a rare opportunity to study how terrestrial biology responds to the very first moments of spaceflight. “For decades, space biology has relied on professional astronauts to carry out experiments designed by scientists on Earth,” Ferl explained. “But to truly understand how biology works in space, I believe you - as the scientist - have to be there. You have to feel the environment.” This September, Ferl and longtime collaborator Anna-Lisa Paul, Ph.D., will be back at Blue Origin’s West Texas launch site, continuing their work with a new series of plant experiments. Ferl and Paul, who directs UF’s Interdisciplinary Center for Biotechnology Research and is a professor in Horticultural Sciences, are tracking fluorescently tagged genes in Arabidopsis plants to study how gene expression changes during the rapid shift from Earth’s gravity to the microgravity of spaceflight and back again. It’s a full-circle moment for Ferl, who remains deeply engaged in the same questions that sent him to space a year ago. Unpacking the Transition from Earth to Space Ferl’s experiment focused on the early metabolic responses of plants during the critical transition from Earth’s gravity to the weightlessness of space. “The scientific community has accumulated plenty of data comparing biology in orbit with that on Earth,” he said. “But we’ve known almost nothing about what happens in those first few minutes as organisms enter space and are exposed to microgravity.” Initial results from the flight reveal intense metabolic changes in the early moments of spaceflight. These changes are distinct from, but connected to, the long-term adaptations seen in orbit. Early Findings, Future Impact While the data from Ferl’s experiment are still on the way to being published, the findings are already shaping the direction of ongoing research. The work contributes to a growing understanding of how terrestrial life, from plants to humans, shares fundamental pathways in responding to the space environment. “This has real implications for the future of space missions,” Ferl noted. “As we send more people and more biology into space in support of exploration, we need a comprehensive understanding of how living systems adapt — right from the start.” Ferl and his team will return to Blue Origin’s launch site in Texas in September to continue their research, sending an uncrewed payload of plants into suborbital space. The flight carries no humans—but it does carry an automated experiment designed to advance their understanding of plant biology in space. It’s part of a broader effort to refine what Ferl calls “researcher-tended missions.” A New Course for UF Space Science The mission has not only shaped the trajectory of Ferl’s research, it has also energized Astraeus and the university’s space biology efforts. “This is about building a new kind of science culture,” Ferl said. “One where the scientists are embedded in every part of the mission, from experiment design to the moment of launch.” As the one-year anniversary of his flight approaches, Ferl remains focused on pushing the boundaries of what science in space can be. But he hasn’t forgotten the magnitude of the moment. “Even a year later,” he said, “the most powerful thing I feel is just: thank you. Thank you for the chance to go, to see it for myself, and to bring that knowledge back to Earth.”
ExpertSpotlight: Why the Strait of Hormuz Matters: The World’s Most Critical Chokepoint
The Strait of Hormuz is one of the most strategically vital waterways on Earth. Just 20 miles wide at its narrowest point, with shipping lanes only a few miles across in each direction, this narrow channel connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. Through it flows roughly one-fifth of the world’s petroleum supply, along with vast quantities of liquefied natural gas, particularly from Qatar. For global markets, the Strait is more than geography, it is a pressure point. Any disruption, even the threat of one, can send oil prices surging and rattle financial markets worldwide. A History Shaped by Empire and Energy For centuries, the Strait served as a maritime corridor linking Mesopotamia, Persia, India, and East Africa. Control over it shifted between regional powers, colonial empires, and eventually modern nation-states. In the 16th century, the Portuguese seized nearby islands to dominate regional trade routes. Later, British naval power asserted influence during the height of imperial shipping dominance. In the 20th century, however, the Strait’s importance expanded dramatically with the rise of oil exports from Gulf states. After the 1979 Iranian Revolution, tensions surrounding the Strait intensified. During the Iran-Iraq War in the 1980s, particularly the so-called “Tanker War” phase, commercial vessels were targeted, highlighting how vulnerable global energy supplies could be. Since then, periodic confrontations between Iran, the United States, and regional powers have kept the Strait at the centre of geopolitical risk. Why It Is So Important Today 1. Energy Security Major oil producers including Saudi Arabia, Iraq, the UAE, Kuwait, and Qatar rely heavily on this route. Even short-term closures could disrupt millions of barrels per day in global supply. 2. Global Economic Stability Because oil is globally traded and priced, disruptions in the Strait impact fuel costs, inflation, shipping, and consumer prices worldwide — including in North America and Europe. 3. Military Strategy The Strait is bordered primarily by Iran to the north and Oman to the south. Iran has periodically threatened to close the passage in response to sanctions or military pressure. The U.S. Navy and allied forces maintain a consistent presence to ensure freedom of navigation. 4. Modern Geopolitical Flashpoint Recent decades have seen drone seizures, tanker detentions, and naval standoffs. Each incident reinforces how fragile global energy logistics can be when concentrated in a single corridor. The Strait as a Symbol of Interdependence The Strait of Hormuz underscores a central truth of globalization: the world’s economies are deeply interconnected and geographically vulnerable. A narrow stretch of water in the Middle East can influence gasoline prices in Ontario, manufacturing costs in Germany, and energy security debates in Asia. It is both a trade artery and a geopolitical lever — a reminder that geography still shapes global power. Expert Angles for Media An expert in geopolitics, energy economics, or maritime security could explore: How vulnerable is the global economy to a prolonged closure? Can alternative pipelines realistically replace Hormuz traffic? What role do regional alliances play in deterring conflict? How does the Strait shape Iran’s negotiating power? What would insurance and shipping markets do in a crisis? The Strait of Hormuz is not simply a map feature — it is one of the world’s most consequential strategic chokepoints. Its stability underpins global energy flows, economic predictability, and international security. If tensions rise there, the world feels it. Our experts can help!

The truth behind federal disclosure of alien life
With the recent presidential comments on potential alien life, UFO enthusiasts have new hope that finally we’re going to get federal “disclosure” of UFOs, aliens and the great government conspiracy surrounding both. But, as a scientist who studies the search for life in the Universe, the question I have is much simpler: What would disclosure really need to disclose? What is required for actual, factual proof that aliens exist and they’ve been visiting Earth? We’ve already had three years of Congressional hearings on UFOs that have produced zero proof of anything. What we need now is simple: hard physical evidence. That is what disclosure needs to deliver. Not stories about alien spaceships being held by the government, but the actual spaceships themselves. Not stories about alien bodies but the actual icky, gooey bodies with their icky gooey tentacles. If disclosure provides physical evidence that independent laboratories and independent scientists all over the world can verify, then it will live up to its hype. That would make “Disclosure Day” truly history-making.
LSU astrophysicist weighs in on potential release of UFO records
Dr. Eric Burns is a leading researcher in high-energy astrophysics, he studies neutron star mergers and gamma-ray bursts and helped lead the first multimessenger discovery of a binary neutron star merger. "Given the vast size of the universe, most scientists think life beyond Earth likely exists, and we are actively searching for it. However, there is no credible evidence that extraterrestrials have visited Earth or made contact with humanity. Previous government reviews of UFO reports have not produced convincing proof of alien technology. Astronomers are terrible at keeping secrets — if even one of us had solid evidence of aliens, the entire world would know by lunchtime. I strongly support transparency and look forward to the release of additional information, but extraordinary claims require extraordinary evidence."
Young magmas on the moon came from much shallower depths than previously thought, new study finds
New research on the rocks collected by China's Chang'e 5 mission is rewriting our understanding of how the moon cooled. Stephen Elardo, Ph.D., an assistant professor of Geological Sciences with the University of Florida, has found that lava on the near side of the moon likely came from a much shallower depth than previously thought, contradicting previous theories on how the moon produced lavas through time. These samples of basalt, an igneous rock made up of rapidly cooled lava, were collected from the near side of the moon by the Chang’e 5 mission and are the youngest samples collected on any lunar mission, making them an invaluable resource for those studying the geological history of the moon. In order to get an estimate of how deep within the moon the Chang’e 5 lava came from, the team conducted high-pressure and high-temperature experiments on a synthetic lava with an identical composition. Previous work from Chinese scientists has determined that the lava erupted about 2 billion years ago and remote sensing from orbit has showed it erupted in an area with very high abundances of potassium, thorium and uranium on the surface, all of which are radioactive and produce heat. Scientists believe that, in large amounts, these elements generate enough heat to keep the moon hot near the surface, slowing the cooling process over time. “Using our experimental results and thermal evolution calculations, we put together a simple model showing that an enrichment in radioactive elements would have kept the Moon's upper mantle hundreds of degrees hotter than it would have been otherwise, even at 2 billion years ago,” explained Elardo. These findings contradict the previous theory that the temperature of the moon’s outer portions was too low to support melting of the shallow interior by that time and may challenge the hypothesis about how the moon cooled. Prior to this study, the generally-accepted theory was that the moon cooled from the top down. It was presumed that the mantle closer to the surface cooled first as the surface of the moon gradually lost heat to space, and that younger lavas like the one collected by Chang’e 5 must have come from the deep mantle where the moon would still be hot. This theory was backed by data from seismometers placed during the Apollo moon landings, but these findings suggest that there were still pockets of shallow mantle hot enough to partially melt even late into the moon’s cooling process. “Lunar magmatism, which is the record of volcanic activity on the moon, gives us a direct window into the composition of the Moon's mantle, which is where magmas ultimately come from,” said Elardo. “We don't have any direct samples of the Moon's mantle like we do for Earth, so our window into the composition of the mantle comes indirectly from its lavas.” Establishing a detailed timeline of the moon’s evolution represents a critical step towards understanding how other celestial bodies form and grow. Processes like cooling and geological layer formation are key steps in the “life cycles” of other moons and small planets. As our closest neighbor in the solar system, the moon offers us our best chance of learning about these processes. “My hope is that this study will lead to more work in lunar geodynamics, which is a field that uses complex computer simulations to model how planetary interiors move, flow, and cool through time,” said Elardo. “This is an area, at least for the moon, where there's a lot of uncertainty, and my hope is that this study helps to give that community another important data point for future models.”
From classroom to cosmos: Students aim to build big things in space
In the vast vacuum of space, Earth-bound limitations no longer apply. And that’s exactly where UF engineering associate professor Victoria Miller, Ph.D., and her students are pushing the boundaries of possibilities. In partnership with the Defense Advanced Research Projects Agency, known as DARPA, and NASA’s Marshall Space Flight Center, the University of Florida engineering team is exploring how to manufacture precision metal structures in orbit using laser technology. “We want to build big things in space. To build big things in space, you must start manufacturing things in space. This is an exciting new frontier,” said Miller. An associate professor in the Department of Materials Science & Engineering at UF’s Herbert Wertheim College of Engineering, Miller said the project called NOM4D – which means Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design – seeks to transform how people think about space infrastructure development. Picture constructing massive structures in orbit, like a 100-meter solar array built using advanced laser technology. “We’d love to see large-scale structures like satellite antennas, solar panels, space telescopes or even parts of space stations built directly in orbit. This would be a major step toward sustainable space operations and longer missions,” said team member Tianchen Wei, a third-year Ph.D. student in materials science and engineering. UF received a $1.1 million DARPA contract to carry out this pioneering research over three phases. While other universities explore various aspects of space manufacturing, UF is the only one specifically focused on laser forming for space applications, Miller said. A major challenge of the NOM4D project is overcoming the size and weight limitations of rocket cargo. To address these concerns, Miller’s team is developing laser-forming technology to trace precise patterns on metals to bend them into shape. If executed correctly, the heat from the laser bends the metal without human touch; a key step toward making orbital manufacturing a reality. “With this technology, we can build structures in space far more efficiently than launching them fully assembled from Earth,” said team member Nathan Fripp, also a third-year Ph.D. student studying materials science and engineering. “This opens up a wide range of new possibilities for space exploration, satellite systems and even future habitats.” Miller said laser bending is complex but getting the correct shape from the metal is only part of the equation. “The challenge is ensuring that the material properties stay good or improve during the laser-forming process,” she said. “Can we ensure when we bend this sheet metal that bent regions still have really good properties and are strong and tough with the right flexibility?” To analyze the materials, Miller’s students are running controlled tests on aluminum, ceramics and stainless steel, assessing how variables like laser input, heat and gravity affect how materials bend and behave. “We run many controlled tests and collect detailed data on how different metals respond to laser energy: how much they bend, how much they heat up, how the heat affects them and more. We have also developed models to predict the temperature and the amount of bending based on the material properties and laser energy input,” said Wei. “We continuously learn from both modeling and experiments to deepen our understanding of the process.” The research started in 2021 and has made significant progress, but the technology must be developed further before it’s ready for use in space. This is why collaboration with the NASA Marshall Space Center is so critical. It enables UF researchers to dramatically increase the technology readiness level (TRL) by testing laser forming in space-like conditions inside a thermal vacuum chamber provided by NASA. Fripp leads this testing using the chamber to observe how materials respond to the harsh environment of space. “We've observed that many factors, such as laser parameters, material properties and atmospheric conditions, can significantly determine the final results. In space, conditions like extreme temperatures, microgravity and vacuums further change how materials behave. As a result, adapting our forming techniques to work reliably and consistently in space adds another layer of complexity,” said Fripp. Another important step is building a feedback loop into the manufacturing process. A sensor would detect the bending angle in real time, allowing for feedback and recalibration of the laser’s path. As the project enters its final year, finishing in June of 2026, questions remain -- especially around maintaining material integrity during the laser-forming process. Still, Miller’s team remains optimistic. UF moves one step closer to a new era of construction with each simulation and laser test. “It's great to be a part of a team pushing the boundaries of what's possible in manufacturing, not just on Earth, but beyond,” said Wei.
Tracking rain patterns will improve hurricane forecasting, UF researcher finds
Studying the precipitation patterns in hurricanes may be key to predicting future storm patterns and their potential strength, a University of Florida researcher has found. Supported by a four-year, $212,000 grant from the National Science Foundation, Professor of Geography Corene Matyas, Ph.D. has identified the patterns of rain rates within storms and studied the moisture surrounding these storms. “We are hoping that, if we have a better prediction of moisture availability, that might help us forecast rain events with greater accuracy,” Matyas said. “The more we know about how storms develop, the more we can predict their path and magnitude.” The ideal stage for the perfect storm The potential for devastating high winds, storm surge and flooding poses an annual threat to Florida and its residents. With 1,350 miles of coastline and relatively flat geography that juts out to separate the warm waters of the southeast Atlantic and the Gulf, Florida creates the ideal stage for the perfect storm. Last year broke records with 18 named storms, including 11 hurricanes in the Atlantic basin and three major hurricanes making landfall along Florida’s coast. Early predictions are crucial to hurricane preparedness, allowing for increased response time and resource allocation, and hurricane modeling is essential for understanding these somewhat unpredictable storms. Advances in technology, data collection and the use of artificial intelligence in hurricane modeling have significantly impacted the ability to predict a storm’s path and strength more accurately. Artificial intelligence helps researchers understand hurricanes Matyas has completed two studies on this topic. The first study processed 12,000 images of rain rates from tropical storms and hurricanes in the Atlantic, using a machine learning algorithm called a convolutional autoencoder. Similar in use to image recognition software, the encoder broke the rain rate images down and simplified the patterns. Six main types, or clusters, of rainfall patterns for tropical cyclones were identified. At a presentation of the work to forecasters at the National Weather Service office in Jacksonville, the forecasters confirmed that one of the patterns matches what they typically see when late-season storms make landfall over Florida’s Gulf Coast. The second study used the autoencoder to process 4,600 images that represent the amount of moisture in the atmosphere extending 1,000 kilometers away from each hurricane. “We looked for commonalities in the patterns and found four dominant patterns of moisture that accompany Atlantic basin hurricanes,” Matyas said. “We found the biggest storms with the most moisture make the most landfalls, typically in the Caribbean and even in southern Florida. They also have a large moisture pool, giving them a bigger chance of heavy rainfall.” According to Matyas, three of the moisture patterns found in the second study were strikingly like those found in the earlier study that used fewer observations in a statistical analysis. With this use of AI, researchers can now recognize and understand these moisture patterns better, which can improve predictions about a storm’s intensity, its size and the amount of rainfall that will result from it. Early, accurate storm predictions allow Floridians time to prepare Rapid intensification – when, in a 24-hour period, a storm experiences a sudden drop in pressure and a dramatic increase in wind speed – creates much more of a challenge for forecasters. “We tend to boil down a hurricane to a set of coordinates which track the middle of a storm,” Matyas said. “And the fastest winds do focus there, but the moisture gets pulled from thousands of kilometers away and the system forces the moisture up. That moisture must go somewhere. So, the outer edges of the storm need to be understood more as well.” Matyas hopes these studies will help scientists classify rain patterns more accurately and consistently. Continued funding for research at public universities from federal agencies, such as the National Science Foundation and the National Oceanic and Atmospheric Administration, is essential for helping researchers develop tools to detect and predict severe weather events. Matyas is one of two UF faculty members among 18 national researchers named to the 2025 class of fellows by the American Association of Geographers. Matyas and UF Geography Department Chair Jane Southworth, Ph.D. were honored by the organization for their contributions in biogeography, geospatial analytics, soil science, community geography, climatology and other areas related to geography. “I look forward to this opportunity to contribute to the mission of the AAG in a more formal capacity, continuing to research how weather shapes our spaces and share knowledge of earth systems beyond the classroom and the written word to promote an inclusive society,” Matyas said.
Why Greenland Matters: The History and Strategic Importance of the World’s Largest Island
Often viewed as remote and sparsely populated, Greenland has long played an outsized role in global strategy. Settled by Inuit peoples for thousands of years, Greenland later became part of the Danish realm in the 18th century and today exists as an autonomous territory within the Kingdom of Denmark. Its location—bridging North America and Europe—has consistently drawn the attention of major powers, especially during moments of geopolitical tension. That attention intensified during the Cold War, when Greenland became a critical asset in Arctic defense. The United States established military installations on the island, most notably what is now known as Pituffik Space Base, to support missile warning systems and transatlantic defense. Greenland’s position along the shortest air and missile routes between North America and Russia made it indispensable to early-warning networks—and that strategic logic has not faded with time. Today, Greenland’s importance is growing rather than shrinking. Climate change is reshaping the Arctic, opening new shipping routes and increasing access to natural resources such as rare earth minerals, hydrocarbons, and freshwater reserves locked in ice. These developments have renewed global interest in Greenland from NATO allies and rival powers alike, as control over Arctic infrastructure, data, and mobility becomes central to economic and security planning. At the same time, Greenland’s own political future—balancing autonomy, Indigenous priorities, and external pressure—adds another layer of complexity. Greenland’s story is ultimately one of geography shaping history. What once made the island strategically valuable for defense now places it at the center of debates about climate, security, energy, and sovereignty in the 21st century. As Arctic competition accelerates, Greenland is no longer a peripheral actor—it is a focal point where global interests converge. Journalists covering geopolitics, Arctic security, climate change, Indigenous governance, or global resource competition are encouraged to connect with experts who study Greenland’s past and its evolving strategic role. Expert insight can help explain why this vast island continues to matter—and why it is likely to play an even larger role in the years ahead. Our experts can help!

The health challenges astronauts Butch Wilmore and Suni Williams face after 9 months in space
On June 5, 2024, astronauts Butch Wilmore and Suni Williams embarked on a brief mission to the International Space Station. But equipment failures turned what was supposed to be an eight-day trip into a grueling 9 month spaceflight. This week, Wilmore and Williams finally returned to Earth. While their safe return is cause for celebration, the journey doesn’t end when astronauts touch down on Earth. They now face the significant task of recovering from the physical and psychological toll of long-duration spaceflight. As part of the University of Florida’s ongoing research into astronaut health, Rachael Seidler, Ph.D., a leading expert in spaceflight-associated health changes, is studying the long-term effects of space travel on astronauts’ brains and bodies. Seidler’s research focuses on understanding how the central nervous system and brain structure adapt to the challenges of space travel, as well as how these changes affect performance, balance, and mobility once astronauts return to Earth. “While the physical and psychological challenges astronauts face after returning from long-duration space missions are well-documented, the research we do at UF is helping us understand the intricacies of their recovery process,” said Seidler, deputy director of the Astraeus Space Institute at UF. “By following astronauts like Butch and Suni before, during, and after their missions, we can track how the human body responds to the extreme conditions of space.” Behavioral and Brain Changes Post-Flight Seidler’s research tracks astronauts’ physical and neurological recovery by observing them both during their missions and after they return. "One of the most immediate challenges astronauts face when they return to Earth is mobility and balance. These issues often recover more quickly compared to others, but it takes time for astronauts to readjust to gravity,” Seidler said. "The balance, mobility, and walking difficulties astronauts experience during the first weeks back are typically resolved in a short period, but brain function and structure require longer recovery periods." Seidler’s research indicates that astronauts’ brains exhibit compensation when they return to Earth following spaceflight. This compensation occurs through the recruitment of additional neural pathways in order to return to their preflight performance levels. However, the recovery of brain function is a gradual process. "This brain functional compensation is typically no longer observed within one to six months post-flight," Seidler said. However, not all changes are reversible. "Brain structural changes, particularly related to fluid shifts in space, show little to no recovery even after six months to a year," Seidler said. Two significant structural changes include the brain physically sitting higher in the skull and the expansion of the brain’s ventricles — fluid-filled cavities in the brain — which can increase in volume by 25% or more. These changes are thought to result from the fluid shifts caused by microgravity, and they present long-term health considerations for astronauts. Long-Term Health Effects: Understanding the Impact As Wilmore and Williams embark on their recovery journey, the long-term impact of these changes becomes a critical focus for researchers like Seidler. "The long-term health impacts are crucial to understand because they could affect how astronauts recover and perform in their daily lives post-mission," she said. Seidler’s team at UF is conducting a new study in which they are tracking astronauts for up to five years post-flight to better understand these long-term effects. "We’ve had astronauts in space for up to a year, and we know how to manage their physical health during those missions," Seidler said. "But the effects of space on the brain and body extend beyond the mission, and our work helps inform strategies to manage recovery." Collaborating with NASA and Studying Spaceflight-Associated Neuro-Ocular Syndrome Seidler's work is also part of a broader collaboration with NASA and other scientists to assess astronaut long-term health. The project is particularly focused on Spaceflight-Associated Neuro-Ocular Syndrome, which affects up to 70% of astronauts. This condition involves structural changes to the eye and optic nerve, leading to vision problems that may impact astronauts’ function. "Neuropsychological assessments can help to measure astronauts’ brain health, while studies of the ocular system help identify potential vision issues that may arise during and after long-duration space missions," she said. Simulating Space Conditions on Earth In addition to studying astronauts on Earth and in space, Seidler’s team conducts experiments to simulate the effects of spaceflight on human physiology. The UF lab runs experiments in head-down tilt bed rest studies, which keep participants lying down for weeks to months at a time to simulate the lack of gravity. "This type of study helps us understand how fluid shifts in the body during space travel affect mobility, balance, and brain structure," Seidler explained. "In addition, other publications have reported that astronauts describe that vestibular galvanic stimulation feels similar to what they experience when they first arrive in space and when they return to Earth. We have equipment to induce these effects in the lab." Looking Toward the Future As space missions continue to grow longer and more complex, UF’s research is more important than ever. "We’re studying these issues now to ensure that future astronauts are prepared for the physical and cognitive challenges that await them in deep space," Seidler said.
