    The Top Dino Discoveries Of 2024 | Can Spiking Eggnog Kill Bacteria From Raw Eggs?
    To wrap up 2024, science writer Riley Black shares her favorite paleontology discoveries of the year. And, if treated properly, even old-fashioned eggnog made with cream and raw eggs can be a safe holiday beverage.The Most Exciting Dino Discoveries Of 2024December is, traditionally, a time to reflect on the events of the past year—including dinosaur discoveries. In 2024, researchers learned more about T. rex and the spiky tails of stegosaurs as well as how dinosaurs evolved, lived, and more.For Smithsonian Magazine, dinosaur enthusiast and science writer Riley Black rounded up her top dino discoveries of the year. She talks with Ira Flatow about the most exciting paleontology news of 2024.Can Spiking Eggnog Kill Bacteria From The Raw Eggs?It’s a question that occasionally comes up over the course of a holiday celebration, at least in certain circles: whether or not the alcohol in old-fashioned eggnog made with real cream and raw eggs can protect against foodborne pathogens such as salmonella.Around 15 years ago, Science Friday investigated, enlisting the help of a lab at Rockefeller University that has a tradition of mixing up a big batch of old-fashioned eggnog around Thanksgiving, then serving it weeks later at a lab holiday party. The researchers kindly conducted a controlled study in which they deliberately spiked samples of their potent eggnog with salmonella, then followed the mixture’s bacterial status over the course of several weeks.Science Friday’s Charles Bergquist checks in with Dr. Vincent Fischetti, a bacteriologist at Rockefeller, to see if there have been any advances in the field of eggnogology.Transcripts for each segment will be available after the show airs on sciencefriday.com.

    Parker Solar Probe Will Make Closest-Ever Approach To Sun
    On December 24, NASA’s Parker Solar Probe will make the closest-ever approach to the sun by a spacecraft. Parker has made more than 20 close approaches to the sun before, but this one will swoop in even closer than 3.8 million miles away from the sun’s surface.Since the probe was launched back in 2018, it’s helped scientists better understand our star and unravel mysteries about solar wind, high-energy solar particles, the sun’s corona and more. Scientists hope that this upcoming approach will reveal even more about the star at the center of our solar system.Ira Flatow talks with Dr. Nour Rawafi, project scientist for NASA’s Parker Solar Probe mission and astrophysicist at the Johns Hopkins Applied Physics Laboratory in Maryland. They discuss the goal of this close approach, how the spacecraft will stand the heat, and what else there is to learn about our sun.Transcripts for each segment will be available after the show airs on sciencefriday.com.

    If ‘Interstellar’ Were Made Today, What Would Be Different?
    For its 10th anniversary, the science advisor for “Interstellar” discusses the film’s impact and how new information about gravitational waves could have changed it.The science fiction film “Interstellar” turns 10 years old this month. For many of us, it was our first encounter with some pretty advanced astrophysics, taking sci-fi concepts like wormholes and time warping, and backing them up with actual science. Now, we’re revisiting the impact that movie’s science had on pop culture, and how astrophysics has advanced in the past decade. If it were made today, what would be different?Ira Flatow sits down with “Interstellar” science advisor Dr. Kip Thorne, a professor of theoretical physics at the California Institute of Technology. Since the film’s release, he has won a Nobel Prize for his contributions to the detection of gravitational waves generated from black holes. They discuss how the film inspired people to pursue scientific careers and how recent astrophysics discoveries, like gravitational waves, could’ve made it into the movie.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

    Farewell, Murder Hornet | What FAA Regulations Tell Us About Mysterious Drone Sightings
    Officials say the invasive Asian giant hornet, with its menacing nickname, has been eradicated from the United States. Also, with drone sightings in the news, we take a look at the current laws and regulations around hobby and commercial drone operation.Farewell, Murder Hornet, We Hardly Knew YouOver the past few years many words have been written about an invasive insect known casually as the “murder hornet”—more formally, the Asian giant hornet, or northern giant hornet. But this week, the USDA and the Washington State Department of Agriculture announced that the insect has been eradicated in the United States. Our long national nightmare is over.Science journalist Maggie Koerth joins Ira to talk about the entomology news, plus other stories from the week in science, including debate over how viruses should be named, the complicated relationship between science and law in the courtroom, and work tracing health signs—through earwax.What FAA Regulations Tell Us About Mysterious Drone SightingsIt’s been all over the news the last few weeks: a slew of drone sightings in New Jersey and elsewhere on the East Coast, starting in mid-November. Federal authorities and President Biden have said that these drones don’t appear to be a threat to public safety, and that the sightings have been a mix of legal drones, airplanes, and helicopters. But questions and concerns remain, particularly among people who live in these areas. And just this week, the Federal Aviation Authority (FAA) banned most drones from flying over nearly two dozen New Jersey towns.Dr. Missy Cummings, professor and director of George Mason University’s Autonomy and Robotics Center in Fairfax, Virginia, has worked on drone technology extensively over the years. She agrees with what federal authorities have said: that these drones sightings are likely legal drones and aircraft, with some prankster drone owners mixed in.Transcripts for each segment will be available after the show airs on sciencefriday.com.
