Emergency response experts say that funding and staff cuts at the National Weather Service could mean less reliable weather forecast. And, babies like music, but they generally have preferences. A music therapist reveals the best kinds of music to soothe a baby.Forecasting Cuts Leave Some Worried For Hurricane SeasonMany in Georgia are still recovering from the devastation of Hurricane Helene last fall.Now, firings and funding cuts at the National Weather Service and other agencies have some experts worried about accurate forecasts heading into the next hurricane season, which begins June 1.Hundreds of workers have been fired from the National Oceanic and Atmospheric Administration, or NOAA, including meteorologists at the Weather Service. More cuts by the Trump administration are reportedly on the way.“The forecast is not going to be as accurate because it won’t have as much information in it,” said Chuck Watson of ENKI research in Savannah, who studies disaster preparedness and response.Read the whole story at sciencefriday.com.Tips For Soothing Your Baby With Music, From A Music TherapistIf you’re a parent, you’ve probably heard that playing music is good for your baby’s brain development. But that’s where many people’s knowledge about the subject ends. What about music is good for a baby’s development? Will queuing up a lullaby playlist get the job done? And how can you tell if it’s all just too much for them?Sarah Nolan, a board-certified music therapist and neonatal intensive care unit music therapist in Children’s Hospital Los Angeles’ Mark Taper and Johnny Mercer Artists Program recently published recommendations on the best ways to play music around your baby.Host Ira Flatow talks to Nolan about the ideal length of time to play music, what kinds of music are best, and the benefits of music therapy to babies and adults alike.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

In January, an iceberg the size of Chicago splintered off from the Antarctic Peninsula and drifted away in the Bellingshausen Sea.As luck would have it, a team of scientists was nearby on a research vessel, and they seized the chance to see what was lurking on the seafloor beneath that iceberg—a place that had long been covered, and nearly impossible to get to.They found a stunning array of life, like octopuses, sea spiders, and crustaceans, as well as possible clues to the dynamics of ice sheets.Host Ira Flatow talks with the expedition’s two chief scientists: Dr. Patricia Esquete, marine biologist at the University of Aveiro in Portugal, and Dr. Sasha Montelli, glaciologist and geophysicist at University College London.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

Mental health information on social media can be both revelatory and misleading. How do clinicians and their patients make sense of it?TikTok and other social media sites are full of mental health content—often short, grabby, first-person videos detailing symptoms for conditions like ADHD and autism. But what does this mean for teens and young adults who spend hours a day scrolling?A new study published in PLOS One analyzes the 100 most viewed TikTok videos about ADHD to assess both how accurate they are and how young people respond to them. Researchers found that about half of the videos were inaccurate or missing key context, and that the more TikToks young adults watched, the less critical they were of the content.For some, watching social videos about mental health conditions led them to better understand themselves and eventually get a proper diagnosis and treatment. For others it made them consider if they have conditions they don’t meet the diagnostic criteria for.Host Flora Lichtman talks with the lead author of the ADHD TikTok study, Vasileia Karasavva, a PhD Student in clinical psychology at the University of British Columbia; and Dr. Jennifer Katzenstein, director of psychology, neuropsychology, and social work at Johns Hopkins All Children’s Hospital in St. Petersburg, Florida.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

Certain words are overrepresented in text written by AI language models. A study investigates why such patterns develop. Also, the ends of chromosomes, called telomeres, typically shorten as an organism ages. But when some fat-tail dwarf lemurs hibernate, they lengthen.‘Delving’ Into The ‘Realm’ Of AI Word ChoiceSeveral years ago, some eagle-eyed readers of scientific papers noticed an unusual trend—an increase in the number of abstracts using certain words. The terms, including “delve,” “realm,” “evolving landscape,” and more, were suddenly appearing more often than they used to.Researchers analyzed the abstracts and compared them to abstracts written just a few years earlier, before the widespread availability of artificial intelligence large language model chatbots. They came to the conclusion that abstracts written by AI were more likely to use words from a list of around 20 favorites than regular human speech. The question was, why? If the models were trained on conventional writing, how did a preference for words such as “delve” creep in?Host Flora Lichtman talks with Dr. Tom Juzek and Dr. Zina Ward of Florida State University, who set out to try to understand the origins of some of AI’s favorite words.When Dwarf Lemurs Hibernate, Their Chromosomes Do Something OddThe fat-tail dwarf lemur is one of the only primates that hibernate for the winter. A new study published in the journal Biology Letters takes a closer look at what’s going on inside lemur cells when they are in this extended phase of suspended animation. It turns out that their telomeres, the ends of the chromosomes, actually grow longer when the dwarf lemurs hibernate. Typically telomeres shorten as we age, as cells continuously divide. So, what exactly does this finding mean for lemurs and other primates, like humans?Host Flora Lichtman talks with the co-authors of this study, Dr. Marina Blanco and Dr. Lydia Greene, research scientists at Duke University.Transcripts for each segment will be available after the show airs on sciencefriday.com.

TB kills more than a million people each year. Dr. Mireille Kamariza has spent her career developing better detection and treatment tools.As the United States retreats from global health leadership—withdrawing from the World Health Organization, dismantling USAID—public health experts warn that there will be implications for the spread of certain diseases around the globe. One such disease is tuberculosis (TB), which is the deadliest infectious disease in the world.If you live in the United States, it’s likely that TB is not on your radar: It’s rare, and if someone is infected, there are effective treatments. But elsewhere in the world, more than a million people die of the bacterium each year, mostly in low-resource, high population regions.Tuberculosis isn’t a straightforward bug to treat. It has a unique armor, which helps it evade treatment like antibiotics. The current treatment regimen involves taking 16 pills a day for six months, which for people in regions with limited access to medicine, can be a massive barrier.Joining Host Flora Lichtman to discuss the science behind this deadly bacterium, and new tools to test for and treat it, is Dr. Mireille Kamariza, a chemical biologist at the University of California, Los Angeles.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Researchers built the largest 3D map of our universe yet. What they found supports the idea that dark energy could have evolved over time.One of the mysteries of the universe is why it expands at the rate that it does. Back in 1998, two teams of researchers observed that not only was the universe expanding, but that the rate of expansion was increasing. That observation was the basis for a concept now known as dark energy. In the years since, cosmologists have been trying to get a handle on better measurements of that effect, and hoping to figure out what dark energy actually might be.This week, researchers on a project called DESI, the Dark Energy Spectroscopic Instrument, released results based on their first three years of data at an international physics conference. They found that it appears possible that dark energy—whatever it is—has changed over the lifetime of the universe. In other words, the so-called cosmological constant may not, in fact, be a constant. The data is not quite statistically significant yet, so researchers can’t definitively say that this is true, which leaves many questions about the nature of dark energy still unresolved.Dr. Andrei Cuceu of the Lawrence Berkeley National Laboratory and Dr. Adam Riess of Johns Hopkins University and the Space Telescope Science Institute join Host Flora Lichtman to talk about the new research, and what remains to be discovered in dark energy.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The framework of Adverse Childhood Experiences started with an unexpected finding over 30 years ago. How is our approach changing? We know that experiences from our childhood, both good and bad, shape who we become as adults. But, understanding what kinds of early experiences have staying power into adulthood and the wide range of impacts they can have is an emerging science.In the 1980s, Dr. Vincent Felitti ran a weight loss clinic in San Diego, California. He noticed that some patients who regained weight were more likely to have experienced sexual abuse in childhood.This eventually led him to conduct research on a larger scale to better understand the correlation between what he and his colleagues dubbed adverse childhood experiences, or ACES, and mental and physical health challenges later in life.This same 10-question survey Dr. Felitti gave participants in the 1990s is still used by researchers and clinicians to assess childhood trauma. But recently, some psychology experts have begun to question how accurately the ACES framework identifies trauma in diverse populations, since it was originally developed for a mostly white and affluent study population.Host Flora Lichtman talks with Preeti Simran Sethi, science writer and Rosalyn Carter Mental Health Journalism fellow, about her reporting for Science Friday about adverse childhood experiences.Also, to see more butterfly stories from our listeners, visit our story from last week. Transcripts for each segment will be available after the show airs on sciencefriday.com.

Former NIH director Dr. Harold Varmus speaks out about what recent budget cuts and policy changes could mean for science.One of the areas targeted by President Trump’s administration for cuts has been the National Institutes of Health (NIH). Cost-cutting actions have included the layoffs of some 1,200 NIH employees, the termination of research grants, a pause in the “study sections” that evaluate and award grant funding, and a cap on indirect costs included in research grants. Some of those moves have been paused following court cases. Dr. Harold Varmus, a former director of the National Institutes of Health, joins Host Ira Flatow to talk about the actions, and the impact he fears they could have on the future of biomedical research in the United States.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Fungal networks in the ground ferry crucial nutrients to plants. But how do brainless organisms form complex supply chain networks? Also, in this year’s baseball spring training, the new Automated Ball-Strike System is helping settle challenges to home plate pitch calls.Scientists Observe Fungi Creating Complex Supply ChainsAs the leaves start to pop out, it’s natural to look up and admire the trees. But actually, there’s a lot of action happening underneath your feet. Beneath you is a complex network of fungal trade routes carrying essential nutrients to the roots of plants, mined from the soil by fungus. It’s a subterranean supply chain.But how exactly do these complex networks form? How does the fungus decide where to ship which resources, or where to build roads? Basically, how does a brainless thread make decisions?Host Flora Lichtman is joined by Dr. Toby Kiers, an author on a recent study of those networks, and professor of evolutionary biology at Vrije University in Amsterdam. She’s also the executive director of the Society for the Protection of Underground Networks (SPUN).A Rookie Robot Umpire Takes The FieldBaseball fans are eagerly awaiting opening day. And while spring training is a time for teams to test out new players and strategies, it’s also a time for Major League Baseball to trial new rules and procedures. One of the things that the league has been testing this year is a robotic system to call balls and strikes.The Automated Ball-Strike System, which is based on the same technology used for line judging in tennis, isn’t calling every pitch, but is used to back up a challenge system at the plate. The tech is already in use in Triple-A games, and could make it to the major leagues in the years ahead. Baseball writer Davy Andrews joins Host Ira Flatow to talk about the technology, and how it could subtly change the rules of the game.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Layoffs at the agency, which releases weather forecasts and monitors extreme weather, could have serious implications. Also, funds for climate and sustainability-focused farming projects have been indefinitely frozen, even though the USDA has already signed contracts.10% Of NOAA Staff Laid Off, With More Cuts PossibleThe National Oceanic and Atmospheric Administration, better known as NOAA, impacts and provides services for Americans every day. The agency releases daily weather forecasts and monitors extreme weather, and it also conducts research into global weather and climate change.Along with many other federal science agencies, NOAA is being subjected to layoffs in the name of cost-cutting: 10% of the agency’s workforce has been laid off, with 1,000 more cuts potentially to come. According to Dr. Timothy Gallaudet, acting NOAA administrator during Trump’s first term, this is likely to lead to declines in quality of service and access to information about weather events.Host Flora Lichtman speaks to Umair Irfan, science correspondent at Vox, who has been covering the turmoil at NOAA. They also discuss other science stories of the week, including the death of prolific blood donor James Harrison.Frozen Climate And Conservation Funds Leave Farmers In LimboAround the country, farmers are planning and planting this year’s crops. It can be uncertain work, made even more tenuous by some of the Trump administration’s changes to climate and conservation policies.The administration has frozen billions of dollars in grants to farmers for sustainable agriculture, conservation, and “climate smart” projects. In some cases, farmers had already signed contracts with the government and begun work on these projects.While some funding from the Inflation Reduction Act was recently released, many farmers across the country are still in limbo.Host Flora Lichtman talks with Patrick Brown, a farmer in Warren County, North Carolina; and Dr. Kitty O’Neil, an agricultural climate resiliency specialist at Cornell University’s Cooperative Extension about the future of farming in a changing climate.Transcripts for each segment will be available after the show airs on sciencefriday.com.
