Hoy, Jorge Laborda habla de la posibilidad de regenerar el corazón tras un infarto. Explica cómo la activación controlada de un gen concreto permite que las células cardíacas adultas vuelvan a dividirse, algo que hasta ahora se creía imposible. Experimentos con células de donantes de más de 40 años demostraron divisiones completas y funcionales sin activar otros tejidos, abriendo la puerta a terapias capaces de reparar el daño del corazón después de un infarto. Por su parte, Ángel Rodríguez Lozano aborda la búsqueda de vida en Encélado, una luna de Saturno. Los datos de la misión Cassini y un estudio reciente respaldan la existencia de un océano global activo bajo la capa de hielo que la recubre. La presencia de compuestos orgánicos, hidrógeno y sílice en los géiseres que emergen por las grietas de la superficie sugiere la existencia de procesos hidrotermales similares a los que, en la Tierra, albergan ecosistemas ricos en vida.

Dr. Alfonso Davila (NASA Ames Research Center)Nov. 24, 2025In 2005, NASA's Cassini spacecraft made a groundbreaking discovery—it found massive plumes of ice and gas erupting from the south pole of Enceladus, a small but geologically-active moon of Saturn. These plumes are now believed to originate from a subsurface ocean of liquid water beneath the moon's icy crust, with conditions compatible with life, as we know it. The talk focuses on our current understanding of Enceladus' plume and subsurface ocean, and on past and future strategies to search in them for possible evidence of life. Alfonso Davila is a Research Scientist in the Exobiology branch at NASA Ames Research Center, where he helps develop strategies to search for evidence of life beyond Earth.
How do planetary ring systems rings form, and what keeps them in line? What exactly is the Dragon Cloud of Saturn? And what's up with quasi moon 2025 PN7? To find out, Dr. Charles Liu and co-host Allen Liu welcome Cornell University's dynamical astronomer Dr. Phil Nicholson for a refresher course in orbital mechanics. As always, though, we start off with the day's joyfully cool cosmic thing, which is right up Phil's alley: the recent discovery of quasi moon 2025 PN7. Phil unpacks the orbital mechanics to explain the critical differences between quasi moons and regular moons, and also 2025 PN7's strange relationship to Earth's orbit. He also explains the dynamics of the sun's tidal forces and Earth's Hill Sphere. For our first question from the audience, Jameson asks, “Are meteorites smaller copies of planets. Are all of them the same?” Rather than discuss meteorites, which are the tiny survivors that have crashed on Earth, Phil pivots to where many of them come from in the first place: asteroids. Really big asteroids share some characteristics with planets, like being spherical in shape, whereas the smaller ones can be highly irregular, like the dumbbell-shaped asteroid 216 Kleopatra, or Arrokoth, previously known as Ultima Thule. Chuck asks Phil about the different shapes large asteroids can come in, and Phil points out 433 Eros, the second largest Near Earth Object, which is banana shaped. The ensuing brief discussion of the “is it a long, skinny asteroid or an interstellar starship?” debate, like the one sparked by Oumuamua, leads to a conversation about Arthur C. Clarke's “Rendezvous with Rama”, which described just such a starship back in 1973. Somehow, we end up looking at the “face” on Mars and the “Death Star,” aka, Saturn's moon Mimus as it was imaged by the Cassini spacecraft. Phil actually worked on the Cassini mission, and Chuck asks him to talk about his experience peering hundreds of miles deep into Saturn's atmosphere with the spacecraft's Visible and Infrared Mapping Spectrometer (VIMS). Along with other instruments run by other teams, the mission changed our perception of Saturn's “boring” atmosphere, documenting aurora, lightning, and giant storms like the “Dragon Cloud of Saturn.” Our next student question comes from Marvin, who asks, “What exactly is a Shepherd moon?” To answer, Phil describes what Saturn's rings are made of, how they form, and how they're structured. He explains what happens when particles that make up the rings collide, why some rings spread over time, while others stay very narrow, and the role Shepherd satellites play in the process. We end with Chuck soliciting a few classic sci-fi recommendations from Phil, who suggests anything by Arthur C. Clarke, the Foundation Trilogy by Isaac Asimov, and almost anything by Larry Niven, including Ringworld, his most famous series.

HT2456 - The Most Memorable Photographs of our Age Time has a way of filtering out the unimportant. Think back 500 years ago. We don't remember local politics, but we do remember the great art from that era. What will people, 500 years from now, look back at our era and find most remarkable? I'll guarantee you it won't be your work or my work, nor even the photographs of the masters like Ansel Adams or Edward Weston. No, they will look back at the images the astronauts captured while on the moon, the Voyager, Cassini, and Juno expeditions to the distant planets, the Hubble and Webb telescope images of distant galaxies.

It’s pretty easy to measure the length of a day on Mars or most other solid bodies. Just pick a feature on the surface and see how long it takes to spin back into view. It’s not so easy for planets that don’t have a solid surface. We can track bands of clouds, but different bands can move at different speeds. That’s been an especially tough problem for Saturn, the second-largest planet in the solar system. Scientists have been trying to pin down its rotation rate – the length of its day – for centuries. When the twin Voyager spacecraft flew past Saturn in the 1980s, they measured the planet’s magnetic field to reveal the rotation rate of its interior. But when the Cassini spacecraft orbited Saturn decades later, its observations showed the day was about six minutes longer. At the end of its mission, Cassini flew between Saturn and the inner edge of its rings. Measuring waves in the rings and tiny changes in the planet’s gravitation field produced yet another length: 10 hours, 33 minutes, and 38 seconds. That’s not necessarily the final answer. Scientists continue to study the giant planet to know how to set their Saturn clocks. And Saturn is in great view tonight.

In Plain Sight: A Memoir Infused with Military Psychological Operationsis the raw, introspective autobiography of Jonathan Mark Haber, a Brooklyn-born activist whose relentless quest for truth spans government conspiracies, military psy-ops, and spiritual awakening.The narrative begins in 1960s Brooklyn, where the assassinations of JFK, MLK, and RFK, the Vietnam War, and nuclear brinkmanship ignite Haber's activism. From draft resistance and communal living to building a family in rural Massachusetts, each step fuels his resolve to expose hidden forces shaping history.Central to his journey is a spiritual and political awakening guided by mentors like Karl Grossman, Elwood Babbitt, Eckhart Tolle, and Manhattan Project/NASA whistleblower Bart Jordan. Their insights propel his work with Flyby News, where he challenges official narratives—from the Cassini flyby and 9/11 to COVID-19—revealing the pervasive reach of military psychological operations.A defining collaboration with Jordan uncovers evidence of ancient Martian artifacts and languages, suggesting a pre-ice-age warning: humanity must break war's cyclical destruction or face oblivion. (Further details are explored in FlybyNews.com and on YouTube: "Bart Jordan: Manhattan Project NASA Whistleblower.")Interwoven with investigative rigor is Haber's personal battle—chronic pain, kidney failure, and profound loss—met with resilience and a belief in love's transformative power. More than a memoir, In Plain Sight is a call to confront deception and forge a future rooted in peace.https://amzn.to/3ImWDCwBecome a supporter of this podcast: https://www.spreaker.com/podcast/the-opperman-report--1198501/support.

Earth has something in common with Titan, the largest moon of Saturn. They’re the only two bodies in the solar system with liquids flowing and ponding on the surface. In the case of Earth, that liquid is water. But on frigid Titan, it’s liquid hydrocarbons – methane and ethane. Titan is the second-largest moon in the solar system – a bit bigger than the planet Mercury. Its surface is extremely cold – hundreds of degrees below zero. Its atmosphere is thicker than Earth’s, and it’s topped by a dense layer of smog. The Cassini spacecraft used radar to peer through the clouds. And its findings were remarkable. It discovered rivers flowing across the surface, emptying into lakes and seas. It also found clouds, which occasionally produce rain. Everything we can see on Titan contains a lot of carbon-based compounds – some of the raw building blocks of life. That’s led to speculation that Titan might have the precursors to life – or even life itself – hidden in a giant ocean below the crust. To be clear, there’s no evidence of life. But future missions to Titan will sniff around for such evidence – perhaps adding to the list of things that Earth and Titan have in common. Saturn appears quite close to our own moon tonight. It looks like a bright star to the lower left of the Moon as they climb into good view, by about 11 o’clock. But you’ll need a small telescope to pick out Titan. Script by Damond Benningfield

Powering spacecraft, especially out in the dark, cold outer solar system, is a huge challenge. There are limits to how large solar panels can be, and they are not very efficient in the weak sunlight beyond Mars. For decades, choice flagship NASA missions have used RTGs--radioisotope thermoelectric generators--to fill this need. From the experiments on the Apollo missions to the Viking Mars landers, Galileo to Jupiter, Cassini to Saturn, and the twin Voyagers, RTGs have provided decades of power for space exploration. From Plutonium to Americium, nuclear elements provide years and years of heat that can be converted into electricity. Dr. Rob O'Brien is the Director of the Center for Space Nuclear Research for the Universities Space Research Association and has specialized in RTGs for decades. It's a fascinating dive into atomic space batteries! Headlines The End of the Universe is Nigh (in 33 Billion Years): New dark matter discoveries suggest an earlier end to the universe, leading to a humorous discussion about bucket list items. August 2nd "Solar Eclipse": Rumors of an August 2nd, 2025, total solar eclipse are false; the next one on that date is in 2027 that won't darken the entire world, but will be the longest one of the century. Mother Earth 2.0 (L98-59f): Discussion of exoplanet L98-59f, 35 light-years away, and its potential habitability despite orbiting a red dwarf with a 23-day year. NASA Budget Concerns: Senate and House pushback against proposed cuts to NASA's 2026 science mission budget is discussed, with calls to preserve vital research. Mass Exodus at NASA: Senior NASA staff, including scientists and engineers, are reportedly leaving due to budget cuts, raising concerns about future capabilities. Main Topic - Dr. Robert O'Brien & RTGs (Radioisotope Thermoelectric Generators) Understanding RTGs: Dr. O'Brien explains RTGs convert heat from radioactive decay into electricity using the Seebeck effect. Early Use of RTGs in Space: The first US public RTG demonstration was on President Eisenhower's desk, and the first space use was the US Navy's Transit 4A satellite in 1961. RTGs on Mars and Deep Space Missions: RTGs power Mars landers and rovers (Viking, Curiosity, Perseverance), and deep space missions like Voyager, Galileo, and Cassini, providing long-term power in harsh environments. Fission Reactors vs. RTGs: RTGs suit small systems and backup power, while fission reactors are better for high-power needs of human expeditions. Plutonium-238 Production Challenges: The scarcity of plutonium-238 is due to its production requiring nuclear reactors and past moratoriums on reprocessing. Americium-241 as an Alternative: Americium-241, abundant in spent fuel and now accessible due to lifted moratoriums on reprocessing, is a viable alternative for powering missions despite lower energy density. Americium in Smoke Detectors and Safety: Americium's safe use in smoke detectors is highlighted, while acknowledging the hazards of working with nuclear materials.

Es gibt zwei große "himmlische" Familien-Clans: die deutsch-baltischen Struves und die italienisch-französischen Cassinis. Der Urvater der Cassinis, Giovanni Domenico, arbeitete an der Sternwarte in Paris und war ein begnadeter Planetenbeobachter. Lorenzen, Dirk www.deutschlandfunk.de, Sternzeit
The world has known many great astronomers, but only a few great astronomy dynasties. One of those celebrates an anniversary tomorrow – the birth of its patriarch 400 years ago. Giovanni Cassini was born in a small Italian village just across the border from Nice, France. Cassini the first, as he’s often called, was the first of four generations of Cassini astronomers. And he definitely was the most productive. He’s best known for his discovery of a gap in the rings of Saturn. It’s named the Cassini Division in his honor. Later, Cassini and his son Jacques theorized that the rings were made of “swarms of tiny satellites” moving at different speeds. They understood the truth many years before it was actually confirmed. More about Cassini and Saturn’s rings tomorrow. Cassini made many other contributions to astronomy. He was among the first to realize that light travels at a limited speed, although he didn’t believe the speed could be calculated. And he developed a law to explain why we always see the same side of the Moon: The Moon takes the same amount of time to orbit Earth as it does to complete one turn on its axis. For most of his career, Cassini was director of Paris Observatory. His descendants kept the job in the family for more than 120 years. Cassini the fourth ended the streak in 1793 – when he left the observatory to write the “stellar” history of this astronomical dynasty. Script by Laura Tuma

Este episodio examina el trabajo de las sondas que orbitan Marte y de los vehículos que exploran su superficie.Saturno reviste un inmenso interés para los investigadores, porque creen que su sistema de anillos comparte similitudes con el disco protoplanetario a partir del cual evolucionó el sistema solar. Este episodio revela el trabajo realizado por la sonda Cassini, que pasó más de trece años examinando el sistema saturniano.
In this episode of The Poetry of Reality, Richard Dawkins engages in an insightful conversation with Carolyn Porco about gene immortality, ancestral traits, the extended phenotype, extraterrestrial life, criticisms of religion and atheism, followed by audience questions.

Food is obviously part of our lives every day. We literally need it to survive. But it can also be an art form and serve as creative inspiration. From fifteenth century still life paintings to pop art, food and art have gone hand in hand for a long time. In this episode, we’ll introduce you to three Pacific Northwest artists whose creativity is inseparable from food. Julie Beeler is an artist and designer based in Trout Lake, Washington. She makes inks, dyes and watercolor paints from the mushrooms she collects in the forest, and she’s the author of the Mushroom Color Atlas. Portland photographer Isabella Cassini captures food in a number of different ways – from carefully arranged kaleidoscope images to her dynamic “splashes, crashes and smashes” series. That series is all about capturing messy food in motion – raw eggs, bowls of cereal and milk and plates of spaghetti get thrown in front of the camera as Cassini captures the midair collisions and spectacular spills. Gena Renaud’s exquisite artwork is actually meant to be eaten. She makes wagashi, or Japanese sweets, meant to be enjoyed as part of a traditional tea ceremony. For most of her career, she was a graphic and industrial designer and worked at companies like Nike and Adidas. Now, she spends time on her meticulous, seasonally-inspired wagashi – delicate, pickled cherry blossoms suspended in wobbly agar, a jelly candy made to look like pieces of sea glass and a confection called manju made with sweet lima bean paste.

Cassini's Mission to Study Saturn's Atmosphere, Ring's and Moons.
Author and space historian Jay Galentine embarks on a thrilling mission to capture the untold story of one of NASA's most influential figures—John Cassani. In his latest book, Born to Explore, Jay takes readers on an exhilarating journey through Cassani's remarkable career, from his unexpected entry into aerospace to his pivotal role in some of NASA's most legendary planetary missions. Cassani wasn't just another project manager—he was a force of nature who refused to accept dead ends, a master of navigating complex challenges, and a mentor who inspired teams to push beyond limits. Jay shares how his original vision for the book transformed when a scheduled 20-minute conversation with Cassani turned into a four-hour deep dive into his personal life, philosophies, and career-defining moments. From the Voyager program to Galileo and Cassini, John's leadership helped shape NASA's approach to planetary exploration, proving that the best missions aren't just about technology—they're about the people who make them happen. Through engaging storytelling, Jay reveals the personal side of Cassani—the man who kept a smile even in the face of budget cuts, mission failures, and relentless obstacles. He also offers insight into Cassani's philosophy of ‘living in a world with no corners,' a mindset that turned potential mission cancellations into historic successes.

Brian Cox and Robin Ince referee as Saturn and Jupiter square up to each other in a planetary face off. Representing team Saturn is space physicist Professor Michele Dougherty, and in the opposite corner is Dr Paul Abel on Team Jupiter. Katherine Parkinson judges this cosmic contest, casting the final vote to decide who will be awarded the coveted Kuiper Belt. It is not all about looks of course, but it is a significant factor in a first impression. Both Saturn and Jupiter score highly in this department, boasting magnificent icy rings and colourful stripes respectively. But what lies beneath their aesthetically pleasing exteriors? How do the planets compare on the inside? The gas giants have been subjects of investigation for many years, with historic missions like Galileo and Cassini uncovering their secrets. But they aren't alone, each planet is surrounded by its own mini solar system of moons, which get space scientists just as excited as their parent planets do. Both Jupiter and Saturn have moons which are hot contenders in the search for extra-terrestrial life and our panel discuss the future plans to explore them.Producer: Melanie Brown Exec Producer: Sasha Feachem Researcher: Olivia Jani
