3 Things A Climate Scientist Learned From Jane Goodall
In a recent Forbes article, Marshall Shepherd reflects on three key lessons he has drawn from the life and work of Dr. Jane Goodall. Shepherd frames Goodall’s legacy—spanning primatology, conservation, and public engagement—as deeply instructive for climate scientists and environmental advocates. He argues that her methods and mindset have more to teach than simply how to observe nature; they speak to how we engage with the world. First, Shepherd highlights immersion: Goodall’s decades of patient observation in the Tanzanian forests demonstrates the power of being physically—and emotionally—present to truly learn from ecosystems. For Shepherd, climate science must go beyond remote data collection: getting into the field and understanding local realities matters. Second, he emphasizes patience. Goodall’s willingness to wait, sometimes for years, for breakthroughs in understanding primate behavior offers a lesson for climate researchers, whose progress may unfold over decades. Third, he admires her tenacity—a commitment sustained over a lifetime, even under adversity. Shepherd suggests that tackling climate change requires that same kind of enduring resolve, especially when public attention or funding waxes and wanes. Through these reflections, Shepherd presents Goodall not just as an icon of conservation but as a model for scientific humility and perseverance. He invites readers to see the parallels between animal behavior research and climate work—and to adopt practices of listening, patience, and resolve in confronting our planet’s changing trajectory.

Cesar Dominguez, a fourth-year chemistry and physics double major at the University of Florida, may be on track to finding alternatives to plastic that could benefit the planet. His impactful work has helped him earn the title of Michelin Science Scholar, and he is now one of a select group of undergraduates connecting scientific research to real-world challenges at Michelin – a global leader in materials science and sustainability. “There’s always this misconception that academic research is completely separate from industry research,” Dominguez said. “Michelin has shown me it’s all one science. You can push discovery forward in both spaces.” Dominguez embarked this fall on a two-semester program of faculty-mentored research, with a $2,000 student stipend and $500 in support funding for his faculty mentor, UF chemistry professor Austin Evans, Ph.D. The program also invites students to present their findings at a spring symposium and tour a Michelin facility in South Carolina. Austin Evans' research aims to control macromolecular structure at all length scales concurrently and deploy materials in the real world. View his profile here Dominguez is furthering his study of how to process ultra-high molecular weight polymers – materials he compares to the scale of “an entire city” rather than a football stadium, through powerful electric fields. By adjusting electrospinning techniques, Dominguez and his team examine how polymers form fibers with different thermal and mechanical properties. These findings could lead to stronger, more sustainable materials, including alternatives to plastics like the major pollutant polyethylene. “All my life, I’ve been told chemistry and physics are separate fields,” Dominguez said. “But I’ve learned they come together in really elegant ways. Being able to unite concepts from both gives me a deeper understanding of how things work.” Dominguez attributes much of his development as a researcher to his work with Evans, who he describes as incredibly supportive, always accessible, and consistently encouraging him to focus on precision and detail. Dominguez also sees UF’s resources as pivotal to his journey. “I feel like what makes the research I'm doing really exciting is the fact that this can only be done at the University of Florida, because we're working with materials that have been developed by scientists here, using equipment that we're very fortunate to have access to here,” Dominguez said. As he prepares to apply to graduate school in analytical chemistry, Dominguez said the Michelin program has expanded his view of what is possible after his degree. “I used to think research only happened in academia,” he said. “Now I know industry is just as vital. It’s opened my mind to different paths for my future.” For now, he offers one piece of advice to other students considering the program: “Do it for the love of the game. If you put passion into your work, everything else will follow.” For more information on the Michelin Science Scholars Program, click here: To learn more about the research happening at UF and to connect with Austin Evans - simply click his icon now to arrange an interview today.
How LSU is Helping Keep Louisiana at the Center of the Nation’s Seafood Map

Strengthening the Seafood Workforce Through outreach programs like Louisiana Fisheries Forward, a partnership between Louisiana Sea Grant and the Louisiana Department of Wildlife and Fisheries, LSU helps fishers and processors modernize their operations. These voluntary programs teach best practices in handling, traceability, and sustainability — directly improving product quality and market reputation. LSU’s extension agents also provide hands-on disaster recovery assistance after hurricanes and market disruptions, helping ensure Louisiana’s seafood workforce remains resilient and ready for the next season. 2. Building Seafood Resilience The total economic value for oysters in 2018 was more than $180 million. Resilience defines LSU’s seafood science. Researchers at the LSU AgCenter and Louisiana Sea Grant are leading selective breeding programs and developing genetic tools to combat disease, temperature changes, and salinity stress. With a powerful combination of hatchery capacity, genetics expertise, and industry collaboration, LSU is helping Louisiana’s seafood industry adapt faster and smarter — protecting both the food supply and the economic backbone of coastal communities. 3. Powering Economic Growth Every part of LSU’s seafood research and outreach ties directly to Louisiana’s economy. AgCenter economists analyze market data and advise state and federal partners on strategies to grow the seafood sector. Meanwhile, Sea Grant specialists help entrepreneurs develop value-added seafood products, from branded lines to ready-to-eat options, that increase profit margins and create new jobs in coastal towns. By helping Louisiana seafood businesses stay competitive, LSU keeps more of the industry’s economic benefits right here at home. 4. Supporting Communities Louisiana’s seafood industry faces constant challenges. LSU’s coastal extension agents and Sea Grant programs provide on-the-ground support to help communities recover and rebuild after disasters. Whether assisting with dock repairs, connecting fishers to relief programs, or helping restart operations, LSU’s commitment ensures that Louisiana’s coastal workforce can weather any storm. 5. Preparing the Next Generation LSU’s work extends from the lab to the dock — and into the classroom. New research and education programs are training future scientists, producers, and entrepreneurs to continue Louisiana’s seafood legacy. For new LSU students interested in the coast, Bayou Adventure, a trip created by the College of the Coast & Environment (CC&E), was designed specifically to educate incoming freshmen about some of the challenges and marvels of the Louisiana coastline. The trip stops at sites that showcase "not just the significance of these areas to the state and nation, but the important work that is being done to sustain and preserve them," said Clint Willson, dean of CC&E. Through workforce development, hands-on learning, and applied research, LSU is shaping the next wave of innovators who will protect Louisiana’s coast and ensure its seafood remains world-renowned. Looking Ahead As the seafood industry faces new challenges and opportunities, LSU’s mission remains clear: to protect Louisiana’s coast, empower its seafood workforce, and ensure the state remains synonymous with the best seafood in America.
LSU Launches Louisiana’s Most Advanced Microscope at Research Core Facility
LSU’s Advanced Microscopy and Analytical Core (AMAC) facility gives Louisiana researchers access to 16 state-of-the-art instruments, including a new Spectra 300 Scanning Transmission Electron Microscope (S/TEM) for atomic-scale imaging and analysis. The new microscope—the most advanced in Louisiana—was installed with $10 million in support from the U.S. Army. Standing almost 13 feet tall on a platform isolated from vibration, the S/TEM required major renovations, including a raised ceiling, acoustic wall panels, and a magnetic field cancellation system to ensure the instrument’s stability and performance. The microscope offers magnification up to 10 million times, powerful enough to enlarge a single grain of Mississippi River silt to the size of Tiger Stadium. “This is a transformational moment for LSU and for the future of research in Louisiana,” Interim LSU President Matt Lee said. “With the installation of the most advanced microscope in the state, LSU is once again demonstrating how we’re delivering on our promises—leading in research, innovation, and service to the state and nation.” The launch of the AMAC and S/TEM demonstrates LSU’s increased investment in providing its faculty and partners with the best possible equipment for research and discovery, including for national defense, energy, and health. “Winning in research is no different than winning in athletics—the best facilities attract the best talent, and you need the best of both to win,” LSU Vice President of Research and Economic Development Robert Twilley said. “Today’s launch is about a state-of-the-art microscope but also the launch of the AMAC as our first research core facility at LSU—the first of more to come to attract, train, and supply the best research talent for Louisiana and build research teams that win.” Using a finely focused electron beam and techniques such as energy dispersive X-ray spectroscopy (EDS) and electron energy loss spectroscopy (EELS), the S/TEM can reveal both structure and chemistry at atomic resolution. These capabilities drive advances in materials science—improving semiconductors, solar cells, batteries, catalysts, coatings, and alloys—while supporting biomedical research by mapping drug delivery, uncovering the structures of viruses and bacteria, and improving medical implant design. LSU’s AMAC research core facility was recently rebranded, changing its name from the Shared Instruments Facility (SIF). Learn more about how AMAC instruments help unlock millions in federal research funding to Louisiana and deliver solutions.
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.

Experts in the Media: Hurricane Season Isn’t Shutdown. A Busy Week Looms For Meteorologists
When you think hurricane season is winding down, think again. Just as many people begin to relax after a stretch of calm weather, the atmosphere often has other plans. Meteorologists are warning that even as we head deeper into October, the tropics are far from done stirring. The “off-season,” as Dr. Marshall Shepherd puts it, can be one of the most deceptive times of year—when attention fades but nature remains restless. Dr. J. Marshall Shepherd is a leading international weather-climate expert and is the Georgia Athletic Association Distinguished Professor of Geography and Atmospheric Sciences at the University of Georgia. Dr. Shepherd was the 2013 President of American Meteorological Society (AMS), the nation’s largest and oldest professional/science society in the atmospheric and related sciences. View his profile here In his recent Forbes article, Shepherd, a leading atmospheric scientist and former president of the American Meteorological Society, reminds readers that the Atlantic hurricane season doesn’t have an on-off switch. While it may appear to be slowing, meteorologists are bracing for a busy week ahead as multiple weather systems continue to develop. He explains that this year’s pattern demonstrates how tropical activity often ebbs and flows, and a lull in storms doesn’t mean the threat has passed. Shepherd highlights how experts are closely watching sea-surface temperatures, wind shear, and atmospheric moisture—factors that can quickly transform calm seas into cyclone breeding grounds. Despite the calendar inching toward November, he warns that conditions remain ripe for sudden storm formation. Ultimately, Shepherd’s message is one of preparedness and respect for nature’s unpredictability. Even when the radar looks clear, the tropics can still surprise us. His call to stay alert is a timely reminder that meteorology is not about predicting the past—it’s about anticipating the next twist in the weather’s unfolding story. Dr. J.

What the First U.S. Chikungunya Virus Case Means: LSU Expert Breaks It Down
"The main vector in the US, Aedes albopictus, is known to have been there so it isn’t terribly surprising that we’d eventually have a case. The fact that is was a local transmission case – meaning that a mosquito transmitted it to someone who had not traveled outside the area – is a bit concerning and points to a couple of things: We need more surveillance for these types of viruses; the fact that it got here means likely someone who had traveled brought it back from their vacation The surveillance infrastructure via the CDC and federal funding has been gutted – which of course is problematic when we have these sorts of introductions occurring. These types of mosquitoes go a little quiet in the fall/winter because it gets too cool for them to be as active as say the summertime. They’re lucky it’s in the fall and not at the start of summer, where the weather would be more conducive to MORE transmission. HOWEVER, as weather patterns change from a combination of climate change and urban development (which creates more heated areas), we’re going to see the times that these mosquitoes are more active becoming longer – which will again mean more opportunities for transmission. Of course, in Louisiana, these mosquitoes are active for a lot of the year. We have good mosquito control, but anyone who sits outside will tell you that doesn’t eliminate biting (though imagine if we didn’t have it) we need to stay vigilant and support the systems that protect us: mosquito abatement, federal and state surveillance, and the science and research that supports our ability to recognize and respond to outbreaks."
