Have Yourself a Sustainable Christmas: Five Tips for a Greener Holiday
As the holiday season approaches, there are multiple ways that individuals and families can employ mindful practices – both meaningful and eco-friendly – that reduce waste and support local communities. From reusable wrappings to sourcing meals locally and composting the leftovers to smarter Christmas tree choices, Baylor University’s Joshua King, Ph.D., professor of English and director of Environmental Humanities minor, and Gary Cocke, senior director of sustainability, offer five tips for embracing sustainability during the holidays to help us reconnect with simpler, more meaningful traditions. Five Tips to Make Your Holidays Meaningful and Eco-friendly 1. Thoughtful gift giving: Choose long-lasting gifts or experiences that recipients will use and appreciate. "Quality over quantity is always a good rule of thumb," Cocke said. “Giving gifts that are useful and durable is best – and if you think of what the recipient would actually be able to use, it is, by its very nature, a more thoughtful gift.” He also encourages exploring and supporting local businesses and the local economy while shopping for unique presents. King added that crafting a creative letter, poem or handmade gift “take us back to the gratitude that should be at the heart of our celebration.” "Experiences can also be wonderful gifts – they often foster lasting memories and meaningful connections," Cocke added. For those looking to give back, donating to a nonprofit organization that resonates with the recipient’s values is a thoughtful gesture. 2. Eco-friendly gift wrapping options An easy way to reduce holiday waste is with intentional gift wrapping. "Choose recyclable paper wrapping over shiny, plastic-laden alternatives and reuse materials when possible," Cocke said. King added that reusable options like fabric and premade bags can be stylish and sustainable. Do-it-yourself wrapping paper can be a fun family activity. “Grab some plain paper and decorate with stamps and markers,” Cocke said. “Grandparents especially love the personal touch of kid-decorated paper." 3. Eat locally and compost Another way to support local businesses is by “sourcing meals locally and making use of leftovers or composting what can’t be eaten,” King said. The Baylor Community Garden offers compost buckets for families to collect their food waste for composting. 4. Greener Christmas tree choices When it comes to Christmas trees, the debate between real versus artificial trees comes down to longevity and disposal. "Artificial trees can be the more sustainable option if used for at least 10 years," Cocke said. "However, real trees are a good choice if properly composted after use." Cocke highlighted the importance of composting and local options for live tree recycling or mulching: 5. A sustainable future “The holidays invite us to practice gratitude and to celebrate relationships we cherish, often by giving gifts, and at Christmas, Christians express gratitude for the ultimate gift: God’s pledge of love to creation through the incarnation, becoming one with us as a fellow creature,” King said. “What better time for practicing a revolution of gratitude through gift-giving and celebrations that are light on the earth and that respect the many relationships by which we live?” Cocke hopes that Baylor’s strategic initiatives and local partnerships will continue to foster sustainable practices, from increasing access to composting to raising awareness about holiday waste reduction. "A little mindfulness can go a long way toward making the holidays more meaningful and sustainable," he said. Looking to know more or arrange an interview?

NASA Missions Discover Record-Setting Blast
Black Hole Eats Star: NASA Missions Discover Record-Setting Blast Dr. Eric Burns, associate professor of Physics & Astronomy in LSU’s College of Science, leads a consortium that studies gamma-ray bursts (GRBs), including the July event that, because of its long duration, stands in a class by itself. Because opportunities to study such events are so rare, and because they may reveal new ways to create GRBs, astronomers are particularly excited about the July burst. Burns discussed the discovery and the significance of this area of research. Can you explain your interest in gamma-ray bursts, why they matter, and how they play into these new discoveries? "I run a consortium that studies gamma-ray bursts. These are the most luminous explosions in the universe, other than the Big Bang itself. The consortium's been operating for almost 50 years. We've seen 15,000 gamma-ray bursts. We've used these sightings to understand the speed of gravity, where gold is created, and fundamental properties in the universe. In July, we detected a gamma-ray burst that was longer than we've ever seen before. They're normally like 30 seconds long. This one was 8 hours. It was so long that we didn't believe it was a gamma-ray burst for a while." What was your role in investigating this phenomenon? "The consortium I run helped find it and helped figure out where it was coming from. We put a bunch of telescopes on it to try and figure out what was happening and to understand what caused this event. Normal gamma-ray bursts come from a massive star near the end of its life. The interior of the star collapses, and it forms a black hole. That black hole eats it from the inside out, and it launches this matter that's moving at basically the speed of light, and that produces your gamma-ray burst. By chance, a colleague and I had written a paper earlier this year on what is the longest gamma-ray burst you could produce with this scenario. And the answer is 1,000 seconds. So we're pretty sure that what happened here was this: You have that massive star, but instead of its core becoming the black hole, instead you have a black hole that falls into it. Or they sort of fall into each other." How was this long gamma-ray burst discovered? And what led to your involvement in studying it? "We have what’s called gamma-ray burst monitors. They're a version of a telescope, but they're not like a long tube that you use to see visible light with your eyes. They're actually crystals that detect when they are hit by a gamma ray by fluorescing and sending out light. And so we could detect them that way. In the consortium I run, there are about a dozen of these gamma ray detectors. They're all on different satellites. Most of them are around Earth, but some of them are much further out in our solar system. We've automated most of our processes. The spacecraft itself will detect this event and report it to the community. All of that happens in like 30 seconds. In this case, our satellite had four different triggers spread over eight hours, and a member of the community pointed out that these events were coming from the same general area in the sky. So, even before the last trigger, within a couple hours, we realized, oh, there's something really long happening here that we haven't really seen before." Full story available here.

Dinosaurs in New Mexico Thrived Until the Very End, Study Shows
For decades, many scientists believed dinosaurs were already dwindling in number and variety long before an asteroid strike sealed their fate 66 million years ago. But new research in the journal Science from Baylor University, New Mexico State University, the Smithsonian Institution and an international team is rewriting that story. The dinosaurs, it turns out, were not fading away. They were flourishing. A final flourish in the San Juan Basin In northwestern New Mexico, layers of rock preserve a hidden chapter of Earth’s history. In the Naashoibito Member of the Kirtland Formation, researchers uncovered evidence of vibrant dinosaur ecosystems that thrived until just before the asteroid impact. High-precision dating techniques revealed that fossils from these rocks are between 66.4 and 66 million years old – placing them in the catastrophic Cretaceous-Paleogene boundary. “The Naashoibito dinosaurs lived at the same time as the famous Hell Creek species in Montana and the Dakotas... They were not in decline – these were vibrant, diverse communities.” – Daniel Peppe, Ph.D. “The Naashoibito dinosaurs lived at the same time as the famous Hell Creek species in Montana and the Dakotas,” said Daniel Peppe, Ph.D., associate professor of geosciences at Baylor University. “They were not in decline – these were vibrant, diverse communities.” Dinosaurs in their prime The New Mexico fossils tell a different story than originally thought. Far from being uniform and weakened, dinosaur communities across North America were regionally distinct and thriving. Using ecological and biogeographic analyses, the researchers discovered that dinosaurs in western North America lived in separate “bioprovinces,” divided not by mountains or rivers, but by temperature differences across regions. “What our new research shows is that dinosaurs are not on their way out going into the mass extinction,” said first author Andrew Flynn, Ph.D., ‘20, assistant professor of geological sciences at New Mexico State University. “They're doing great, they're thriving and that the asteroid impact seems to knock them out. This counters a long-held idea that there was this long-term decline in dinosaur diversity leading up to the mass extinction making them more prone to extinction.” Life after impact The asteroid impact ended the age of dinosaurs in an instant – but the ecosystems they left behind set the stage for what came next, the researchers said. Within 300,000 years of their extinction, mammals began to diversify rapidly, exploring new diets, body sizes and ecological roles. The same temperature-driven patterns that shaped dinosaur communities continued into the Paleocene, showing how climate guided life’s rebound after catastrophe. “The surviving mammals still retain the same north and south bio provinces,” Flynn said. “Mammals in the north and the south are very different from each other, which is different than other mass extinctions where it seems to be much more uniform.” Why the discovery matters today The discovery is more than a window into the past – it’s a reminder of the resilience and vulnerability of life on Earth. Conducted on public lands managed by the U.S. Bureau of Land Management, the research highlights how carefully protected landscapes can yield profound insights into how ecosystems respond to sudden global change. With a clearer understanding of the timeline of the dinosaurs’ final days, the study reveals not a slow fade into extinction but a dramatic ending to a story of flourishing diversity cut short by cosmic chance.

RPI Awarded Air Force Grant to Monitor Growing Traffic Between Earth and Moon
As nations and private companies prepare to ramp up the number of missions to the Moon, researchers at Rensselaer Polytechnic Institute (RPI) and Texas A&M University have secured a $1 million grant from the Air Force Office of Scientific Research to develop a system to track and monitor resident space objects — including spacecraft, satellites and debris — moving through the vast cislunar space between the Earth and the Moon. The initiative, called RCAT-CS (Reconfigurable Constellations for Adaptive Tracking in Cislunar Space), will develop intelligent networks of sensor satellites that can be reconfigured to perform resilient tracking of objects as they maneuver through this complex orbital environment. "Right now, we're seeing an explosive growth in cislunar missions, including everything from commercial lunar landers and orbiters to next-generation spacecraft that secure national interests in this contested domain," said engineering professor Sandeep Singh, Ph.D., RPI’s lead investigator on the project. "But our ability to track what's happening out there hasn't kept pace. Ground-based sensor systems have blind spots and cannot reliably provide measurements. A space-based constellation is the answer, but placing spacecraft in orbit is expensive and solving the resource constraint problem is essential." The cislunar region presents unique challenges for space domain awareness applications. Competing gravitational forces from the Earth and the Moon create complex orbital dynamics, while the sheer distances involved make tracking difficult. When spacecraft and satellites perform maneuvers in this space or behave unexpectedly, current systems can lose track of them entirely. RCAT-CS will tackle these problems by designing constellations of space-based sensors that can dynamically reposition themselves based on what they're observing. Professor Singh and his colleagues will develop novel algorithms to detect maneuvers made by tracked objects, balance fuel costs, track performance of the sensing satellites, and quantify the uncertainties underlying it all. The system addresses critical safety and security needs as cislunar space becomes increasingly congested and contested. The research will also advance fundamental knowledge in orbital dynamics and autonomous space systems, with implications for mission planning, collision avoidance, and safe coordination of a growing cislunar economy. Additionally, the project will train the next generation of space engineers in cutting-edge technologies essential for American leadership in space operations. “Congratulations to Professor Sandeep Singh and his team on securing a research grant in the important area of lunar space exploration,” said Shekhar Garde, Ph.D., the Thomas R. Farino Jr. ’67 and Patricia E. Farino Dean of the School of Engineering. “RPI has always been at the frontier of space exploration, from George Low’s work on the Apollo program to the forthcoming Artemis II mission, led by Commander Reid Wiseman ’97.” “Professor Singh’s work will not only advance research, it will strengthen RPI’s recently launched Aerospace Engineering undergraduate program by bringing the latest research into our classrooms,” Garde added.

UD physicists track one of the most powerful solar flares in nearly two decades
A massive solar flare – possibly the strongest recorded in nearly 20 years – has unleashed a wave of charged particles toward Earth, sparking radio blackouts across parts of Africa and Europe and triggering measurable increases in radiation levels worldwide. At the University of Delaware, physicists Pierre-Simon Mangeard and John Clem are closely monitoring the event through UD’s neutron monitor network, a global system that tracks cosmic radiation from observatories in Newark, Greenland, Canada, Antarctica and Hawaii. “This is a significant event, still in progress,” said Mangeard. The physicists are seeing a roughly 65% increase in ground-level radiation, which is possibly the largest since 2006. These elevated readings are known as a Ground Level Enhancement (GLE) – a rare occurrence caused by high-energy particles accelerated by solar flares that penetrate Earth’s magnetic field and reach the surface. The data being collected now will help researchers better understand how such bursts of solar activity impact Earth’s atmosphere, communications systems and even aviation safety. Clem and Mangeard’s work at UD’s Bartol Research Institute and Department of Physics and Astronomy contributes to global efforts to monitor and predict space weather events, including solar storms and coronal mass ejections. The team’s continuous, real-time data help scientists worldwide assess potential disruptions to satellites, power grids and high-altitude flights. As analysis of this flare continues, UD’s neutron monitor network will remain a key resource for understanding how space weather events ripple through our planet’s systems. Experts available for interviews: • Pierre-Simon Mangeard, research associate, Department of Physics and Astronomy • John Clem, associate professor, Department of Physics and Astronomy To contact Mangeard or Clem, email mediarelations@udel.edu.

Mosquito-borne disease research featured ahead of climate conference
University of Florida medical geographer Sadie Ryan, Ph.D. is among the international scientists whose work is featured in the forthcoming “10 New Insights in Climate Science” report, which will be presented at the United Nations COP30 Climate Conference on Nov. 10. Ryan’s research, which examines how climate change influences the spread of mosquito-borne diseases such as dengue, contributed to a newly generated global map illustrating where shifting temperatures and rainfall patterns are making conditions increasingly suitable for disease transmission. “A lot of my research is about how vector-borne diseases are going to move as the climate changes, and what that means for where and when transmission can happen,” Ryan said. “Climate change isn’t the only driver of dengue’s spread, but we are seeing the bleeding edge of climate shifting those distributions, where it’s warm enough for long enough and wet enough at the right times for outbreaks to take off.” According to Ryan, the map included in the report is based on the most recent generation of climate models and directly illustrates how climate suitability for dengue is changing around the world. Produced annually by Future Earth, the Earth League and the World Climate Research Programme, the report synthesizes the most important developments in climate research at the intersection of climate, health and policy on the world stage.

Humanities play integral role in the UF Astraeus Space Institute
The ability to imagine has given the human species the power to create, problem solve, empathize, and theorize. In fact, creative imagination can be found at the origin of every modern development throughout time. From medical advancements and the formation of governments to the establishment of the internet and the creation of Beethoven’s Symphony No. 3 — all at first were simply imagined. So, it is not a leap to think that in establishing a space institute at the University of Florida, collaborators would continue to anchor the institution in the human element of imagination. That’s where space exploration began. Ancient Greek philosopher Thales, later known as the father of Greek science and mathematics, questioned the true origins of the universe. Introducing deductive reasoning, Thales sought answers beyond the stories of gods and heroes. Three hundred years later, Aristotle theorized the geocentric layout of the universe with Earth at its stationery core and celestial bodies revolving around it. In the early 14th century, the Italian poet Dante told the story of a vertical journey through the universe, reaching the stars in what he described as paradise. And in the fall of 1609, Galileo began observing the heavens with instruments he created to magnify his view up to 20 times beyond what the natural eye could see. Through his telescope, Galileo observed mountains on the moon, rings around Saturn, and the moons of Jupiter, all evidence that the universe did not revolve around the Earth, but the sun. Inspired by words written in 1865 by Jules Verne in his novel, “De la Terre à la Lune” (From the Earth to the Moon), a 10-year-old Russian boy questioned, could travel be possible beyond the Earth’s atmosphere? Could Verne’s 900-foot-long space gun propel humans — or anything for that matter — through the bonds of gravity and into outer space?

On Sunday, October 19, at 9:34 a.m., four masked individuals surged into the Louvre’s Galerie d’Apollon from a severed, second-floor window. Hurriedly, they smashed open two display cases, seized eight pieces of jewelry, then shimmied down a ladder and sped off on motorbikes toward Lyons. In seven minutes’ time, in broad daylight, they absconded with an estimated $102 million in valuables from the world’s most famous museum. This past Saturday, October 25, French authorities announced the first arrests in connection with the daring heist. However, despite the police’s progress, the country continues to litigate the matter—embroiled in discussions of heritage, history and national identity. Recently, Roderick Cooke, PhD, director of French and Francophone Studies at Villanova University, shared his perspective on the situation as well as the artifacts lost. Q: The Louvre heist has been described as “brazen,” “shocking” and a “terrible failure” on security’s part. Is there any sort of precedent for this event in the museum’s history? Dr. Cooke: Nothing on this scale has ever happened to the Louvre since its founding as a museum during the Revolution. The closest equivalent is the 1911 theft of the Mona Lisa by a former employee who claimed it should be returned to Italy. However, that was one painting, the heist was not committed by organized crime, and the Mona Lisa did not have the renown it enjoys today. The impact of the theft was thus lower, although it did cause major outrage and a sweeping law-enforcement response at the time. Ironically, that theft is often credited with making da Vinci’s painting the global icon it continues to be. Q: What has the reaction to this event been among the French people? DC: It’s harder to get a sense of reactions across French society, because so much of the aftermath has focused on the intellectual milieux’s opinions. And in those realms, it has immediately become a political football. Individuals positioning themselves as anti-elite or anti-status quo, such as Jordan Bardella of the National Rally party, have called the theft a “humiliation,” immediately tying it to French national prestige. Former President François Hollande has conversely and vainly called for the event to be de-polemicized, citing national solidarity. This is happening because the Louvre is one of the most visible manifestations of French soft power—the most-visited museum anywhere on Earth. As such, anything attacking its integrity becomes an attack on the nation, and how individual French citizens feel about the theft is closely tied to their broader view of the nation. Q: Several of the items stolen from the Louvre once belonged to Empress Eugénie. Could you share a bit of information on her story? DC: Eugénie de Montijo was a Spanish aristocrat who married the Emperor of the French, who ruled as Napoleon III between 1852 and 1870. It was a time of authoritarian repression and sham democracy—Napoleon III installed the Empire through a coup. Its clearest legacy is that Paris looks the way it does today largely because of the thorough modernizations overseen by Napoleon III’s appointee Baron Haussmann. So, Eugénie and her now-lost jewels represent a complex point in French history, when culture and the economy developed quickly, but did so in a climate of fear for any French person who opposed the regime too loudly (like Victor Hugo, who went into exile on the Channel Islands and wrote poems savaging Napoleon III and his deeds). Some accused the Empress of being responsible for the more hardline and conservative stances taken by her husband’s government. On a different note, she was a diligent patron of the arts and arguably the most significant figure in the contemporary fashion world, famous for setting trends such as the bustle that radiated across Europe. This explains the mix of anger and admiration that followed her depending on the sphere she was operating in. A new English-language biography argues that far from being a traditionalist, she was a pioneering feminist by the standards of the time. It looks like her historical importance will continue to be debated. Q: Interior Minister Laurent Nuñez described the stolen items as “of immeasurable heritage value.” How significant of a cultural loss do you consider this theft? DC: These jewels are referred to in French as “les Joyaux de la Couronne” (the Crown Jewels), but of course that phrase lands very differently in republican France than it does across the water in the United Kingdom. The items actually represent several different dynasties of French rulers, some of whom came to power through direct conflict with others. The now-ransacked display at the Louvre smoothed over these historical divisions, for which many French people died over the centuries. President Macron referred to the stolen items as embodying “our history,” which is emblematic of the French state’s work to create a conceptual present-day unity out of the clashes of the past. At a time when France is arguably more divided than at any point since World War II, any unitary symbol of identity takes on greater significance. Q: Do you have any closing thoughts on the artifacts taken and what they represent? DC: I’d reemphasize the previous point about the smoothing effect of the museum display on the violent history that made it possible. Much of the reporting on the stolen jewels lists off the different queens and empresses who owned them, without giving readers a sense of the complicated succession of regime changes and ideologies that put those women in power in the first place. The relative stability of the last 60-odd years is an anomaly in modern French history. This set of jewels and the names of their original owners may seem far removed from the concerns of an ordinary French citizen today, but just beneath their surface is a legacy of changing governments and tensions between social classes that survives in new forms in 2025.

Batty pathogens: Why do bats spread so many diseases?
Let’s face it — bats get a bad rap. Their links to disease outbreaks and their spooky association with vampires influence their notoriety. In reality, bats are truly remarkable. Bats support our agricultural industries as vital members of food webs. And, contrary to their portrayal in popular Halloween blockbusters, they are gentle and tidy creatures that groom themselves like cats. So why is it that when we hear of disease outbreaks, it always seems to be bats? According to University of Florida Emerging Pathogens Institute member Jim Wellehan, D.V.M., what sets bats apart isn’t black magic at all. But rather, it’s their long history of co-existing with viruses, the unique tradeoffs of flight and, perhaps most of all, a history of adapting to new pathogens. “(Infectious disease) has been the biggest factor in all of evolution,” said Wellehan, who is also a professor at the UF College of Veterinary Medicine. “People are always looking for an excuse (as to) why bats are magic, and the truth is bats have just been exposed to a lot of stuff and selected for those genes accordingly.” While humans are the most populous mammals on Earth, bats are a massive group of animals. Behind rodents, they represent the second-largest group of mammalian biodiversity, accounting for a whopping 20% of all mammal species. With over 1,400 species, it’s no surprise that pathogen diversity in bats is just as extensive and complex. Jim Wellehan's research focuses on comparative infectious disease, pathogen evolution, molecular diagnostics and pathogen discovery. View his profile here Bats, as we know them, have been on Earth for over 50 million years. This extensive period has given pathogens plenty of time to evolve alongside the winged mammals. Bats carry viruses like Ebola, Hendra virus, Nipah virus and SARS-CoV-2, which causes COVID-19. One factor that is important in this viral diversity is flight. Flight provides bats with many evolutionary advantages, such as predator evasion, access to new food sources and the ability to exploit diverse habitats. Flight also dramatically increases the chance of rapid pathogen transmission, as they can travel long distances and past many geographic barriers. Many species are highly social, which increases transmission rates as they live in close proximity and groom one another. “When I first learned about Darwin and evolution, ‘survival of the fittest,’ I assumed, meant ‘smartest and fastest and strongest,’ but if you look at our genomes, turns out that's wrong,” said Wellehan. “The genes that are selected for are mostly immune-related. The most important thing is to have enough genetic diversity in your population so that someone has immunity genes that are effective against the next pathogen that doesn't even exist yet. With their increased mixing and contact rates, bats have done this more often than most animals.” Generally, pathogens are most likely to cause disease when they first infect a new host species, as the susceptible animals have not yet developed the necessary defenses. Pathogens, along with their hosts, have no choice but to evolve to survive. With such a wide variety of species, it is not surprising that bats also carry a large proportion of mammal-associated viruses. This is not to say that bats are immune to all pathogens. As the most rapidly evolving factor in life, infectious disease is an incredibly dynamic part of medicine. Bats can get sick from lyssaviruses, including rabies. Additionally, white nose disease, a fungal infection that targets hibernating bats, has been a growing concern in the United States for the past decade. Though bat pathogens are a significant concern, habitat disturbance plays a larger role in bat population pathogen emergence, ultimately affecting humans as the dominoes fall. “Pathogen transmission to humans and conservation efforts go hand in hand,” Wellehan said. “When populations get under stress, that's when ecological balances get shifted, and zoonotic jumps occur. ... It turns out that if we think of ourselves as something separate from nature, it doesn't work so well.” So, while bats may embody the spirit of Halloween, their “magic” lies in evolution and resilience, shaped by millions of years of flying in the face of viruses, not spooky legends.
