Experts in the Media: CBD may help treat and reduce inflammation in Alzheimer's disease

In a recent Medical News Today article, Corrie Pelc reported on a study led by Babak Baban, PhD, in which inhaled CBD (cannabidiol) was tested in a mouse model of Alzheimer’s disease to examine its effects on neuroinflammation. Baban, associate dean for Research with AU's Dental College of Georgia and a professor with appointments in neurology and surgery in the Medical College of Georgia at Augusta University, explained that previous work from his group showed inhaled CBD to be more effective than oral or injected forms for certain neurological conditions, motivating them to explore its potential in Alzheimer’s research. He emphasized that Alzheimer’s is driven by multiple interacting biological processes – not just amyloid plaques – and sees inflammation as a promising new therapeutic target. In the study, inhaled CBD lowered activity in two major immune “alarm” pathways – IDO (indoleamine 2,3-dioxygenase) and cGAS-STING – both implicated in chronic inflammation. By dampening these pathways, CBD reduced levels of inflammatory cytokines and helped restore a more balanced immune environment in the brain. Baban framed this as a shift from symptom treatment to addressing underlying immune dysfunction, and noted that the findings could reorient how Alzheimer’s is approached. At the same time, he stressed that human trials are still needed: his team is preparing translational studies and holds an active Investigational New Drug (IND) application with the FDA for inhaled CBD in neuroinflammatory conditions, with Alzheimer’s disease as a natural next step.

Florida needs veterinarians trained to respond to natural disasters. Congress can help.

When Hurricane Helene struck, we were on the frontlines in Florida’s Big Bend region, racing against time to support the Humane Society as they rescued animals displaced by the most powerful storm ever to hit this part of the state. Two weeks later, we were back in action, facing the devastating flooding from Hurricane Milton. These back-to-back disasters showcased the urgency and critical need for emergency-response veterinarians who can act fast to save lives. We lead one of the nation’s only three emergency veterinary response teams — the University of Florida Veterinary Emergency Treatment Service (UF VETS). Founded after the 2004 hurricane season and operating under the UF College of Veterinary Medicine, the UF VETS program hosts two distinct, yet complementary, branches: a medical response unit for disaster-affected animals and an animal technical rescue branch, which manages complex operations like overturned livestock trailers. Larry Garcia specializes in veterinary disaster preparedness and response, animal technical rescue/training and shelter medicine operations. View his profile here Our team is on call whenever disaster strikes, working alongside local and state veterinary organizations, animal rescues and law enforcement to save animals in crisis. But here’s the problem: Without a nationwide system for coordinating these efforts, it’s often chaotic, and animals suffer because of it. Now Congress has a golden opportunity to change that. As they return to Washington, they have the chance to make a game-changing impact by including funding in the final FY 2025 Homeland Security Appropriations bill to create a nationwide network of veterinary emergency teams. This funding could revolutionize how the U.S. handles animal care during national disasters — and it needs to happen, fast. Read more ...

Multi-university AI research may revolutionize wildfire evacuation

As wildfires grow wilder, the University of Florida and two other universities are developing large language models to make evacuations safer and more efficient. Armed with a nearly $1.2 million National Science Foundation grant, UF, Johns Hopkins University and the University of Utah are creating these AI-based models to simulate human behavior during evacuations – information that will help emergency managers shape more effective evacuation plans. “Strengthening wildfire resilience requires accurate modeling and a deep understanding of collective human behavior during evacuations,” said UF project lead Xilei Zhao, Ph.D., an associate professor with the Engineering School of Sustainable Infrastructure and Environment. “There is a critical need for simulation models that can realistically capture how civilians, incident commanders and public safety officials make protective decisions during wildfires.” Xilei Zhao focuses on developing and applying data and computational science methods to tackle problems in transportation and resilience. View her profile here Existing simulation models face limitations, particularly with reliable predictions under various wildfire scenarios. New AI models can simulate how diverse groups of people behave and interact during the hurried scramble to seek safety. Zhao’s team is developing a convergent AI framework for wildfire evacuation simulations powered by psychological theory-informed large language models. The project will produce simulation methods to promote teaching, training and learning, and support wildfire resilience by allowing public safety officials to use open-access tools. “This research seeks to be a transformative step toward improving the behavioral realism, prediction accuracy and decision-support capability of wildfire evacuation simulation models,” Zhao said. Zhao partnered with John Hopkins professor Susu Xu, Ph.D., and University of Utah professors Thomas Cova, Ph.D., and Frank Drews, Ph.D. The preliminary results of the study were recently presented at the 63rd Annual Meeting of the Association for Computational Linguistics. “In that paper, we started to train the model on the survey data we collected to see how we can accurately predict people's evacuation decisions with LLMs,” Zhao said. Research objectives include extending the Protective Action Decision Model for civilians and public safety officials, developing psychological theory-informed large language model agents for protective modeling and generating a realistic synthetic population as input for the simulation platform. The team also plans to develop learning-based simulations and predict human behavior under scenarios such as fire spread, warning and infrastructure damage. This research comes at a critical time, as the number of wildfires has significantly increased globally. About 43% of the 200 most damaging fires occurred in the last decade leading up to 2023, according to a recent study in Science. The intensity, size and volume of wildfires are threatening more urban areas. “If you go into the urban area, many people do not have cars, or they need additional mobility support,” Zhao said. “For example, the LA fires impacted nursing homes with a lot of elderly people, many of whom are immobile or lack the ability to drive. That's a big problem. This would be very relevant to them.” The large language models will provide important context for evacuation planning as well as real-time decision making. “We envision this tool being used during planning,” Zhao said, “so emergency managers can test different kinds of scenarios to determine how to draw the evacuation zones, where to issue the orders first and how to design the communications messaging.” This is important research and critical as wildfires become more common across North America.  If you're a reporter looking to connect and learn more - then let us help.

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.

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.

Gig worker protection law boosted overall earnings but dropped hourly pay

A 2020 California law designed to protect gig workers by classifying them as regular employees, rather than contractors, ended up increasing their earnings by about 8%. However, their hourly pay dropped by 1.6% as companies offset the higher costs of benefits. Workers’ increased earnings came from working longer hours in order to qualify for and reap benefits like employer tax sharing. These findings come from a study led by Liangfei Qiu, Ph.D., a professor in the University of Florida’s Warrington College of Business, which examined nearly 400,000 monthly work records from about 41,000 freelancers on Upwork, one of the world’s largest online labor platforms. That trove of data let the researchers ask what actually happened when the law, known as AB5, took effect. Qiu’s is the first study to reveal how AB5 affected workers’ income and comes as other states consider passing similar laws. Liangfei Qiu is an expert in social technology, including social media and social networks, as well as artificial intelligence. View his profile here “It highlights some unintended consequences,” Qiu said. “If the labor market competition is similar to what we observe in California, then you might get lower hourly rates for gig economy workers and longer working hours.” “But it’s nuanced. In surveys, gig workers said they were willing to work longer hours because they had better benefits. The outcome depends on how involved someone is in the gig economy,” Qiu added. AB5 was designed to correct what labor advocates saw as widespread misclassification of a company’s essential employees as independent contractors, who don’t typically earn any benefits. This classification gives companies a cheaper workforce, and provides maximum flexibility for workers, but doesn’t allow workers to earn any sick leave, vacation or health insurance. Self-employed contractors must also pay the full share of Social Security and Medicare taxes, which works out to about 15% of gross income. Gig economy companies fought back against the AB5 regulations. A company-sponsored ballot referendum, Prop 22, exempted well-known giants like Uber, Lyft and DoorDash from the law later in 2020. And the California legislature provided further carve outs for professions like doctors, lawyers and photographers. The law still applies to contractors used by delivery companies like FedEx, UPS or Amazon, home-service companies like Angi or Rover as well as online freelance platforms like TaskRabbit. The study is forthcoming in the journal Information Systems Research. Qiu collaborated on the analysis with researchers at Baylor University, Santa Clara University and Stony Brook University.
