Science Friday

United States

Covering everything about science and technology -- from the outer reaches of space to the tiniest microbes in our bodies -- Science Friday is your source for entertaining and educational stories and activities. Each week, host Ira Flatow interviews scientists and inventors like Sylvia Earle, Elon Musk, Neil deGrasse Tyson, and more.


Hr2: Vibrato Physics, Satellite Repair, Charting Physics History  

Physicist Lawrence Krauss on the substance of the universe, the Higgs Boson, and how we know what we know. Plus, researchers use the tools of quantum physics to quantify the vibration of sound. And a robotic spacecraft could improve weather forecasting by fixing satellites in geosynchronous orbit.

Hr1: News Roundup, Autonomous Ambulances, New York 2140, Climate and Food  

In his new novel, New York 2140, author Kim Stanley Robinson tackles how a drowning city might adapt and thrive after disastrous sea level rise. Plus, as the globe warms, maple syrup, tea, and other specialty foods could suffer from lower quality and lower nutritional value.

Hr2: Atmospheric Microbiome, Content Moderation, Scraps for Dinner  

In their book Scraps, Wilt & Weeds, Mads Refslund and Tama Matsuoka Wong describe creative ways to use the parts of produce that we usually toss away. Plus, a look at how content moderators work behind the scenes to keep graphic content off your feed. And why certain types of bacteria in the atmosphere can play a role in rain and snow.

Hr1: News Roundup, Gamifying Communication, Trump and the EPA, Tuvan Throat Singing  

How the president and Congress have been quietly and successfully tearing down U.S environmental and climate change policy. Plus, Tuvan throat singers have developed a technique that allows them to produce two notes at one time.

Hr2: Ancient Earth Crust, Farmers and Conservation, California Water Supply  

Some farmers are using techniques like no-till and dry irrigation that conserve natural resources as a way to cultivate crops according to the biology of the soil and land. Plus, predicting rain, snow, and water supply in the warming west.

Hr1: News Roundup, Bee Intelligence, Genetic Data Storage  

Bees are more intelligent than we thought, and can count and recognize faces. Plus, could DNA become a mainstream data storage option?

Hr2: Antibiotic Discovery, Regrowing Sensory Hair in the Ear, Trappist-1 Exoplanets  

Scientists have discovered seven Earth-size planets orbiting a nearby star that could hold the conditions for life. Plus, a look at the scientific obstacles and breakthroughs involved in finding and developing new antibiotics. And Boston-based researchers have regrown a high volume of sensory hair cells in the lab using a new technique.

Hr1: News Roundup, Gene Editing Embryos, Computer Hacks of the Future, and How to Prevent Them  

As self-driving cars and other artificial intelligence advance, how safe will we be from A.I. hacks and attacks? Plus, a report from a National Academies panel endorses the possible use of gene-editing techniques in human embryos -- under very limited conditions.

Hr2: Net Neutrality, The Price of Privacy, Expanse  

As we trade more and more of our personal data to big companies in exchange for their services, internet users must decide for themselves where to draw the line on internet privacy. Plus, the minds behind the The Expanse chat about space flight, space politics, and how they keep the show feeling real.

Hr1: News Roundup, Emotion Translator, Battery Technology  

Is there a new battery that can beat lithium ion in electric vehicles? We plug into the world of battery research to find out. Plus, how to squeeze more power out of the electrical grid. And a new wearable aims to help people who feel socially awkward interpret emotions.

Hr2: Heat-sensitive Prosthetic Skin, Flint Water, Ingestible Electronics  

Three years after the Flint water crisis began, lead concentrations in the water are below federal action levels, but residents are still drinking filtered and bottled water. Plus, researchers have designed a battery that runs on stomach acid to power ingestible sensors.

Hr1: News Roundup, Ice, Holographic Cosmology  

Researchers who study icy places have discovered uncanny phenomena. Plus, Holographic cosmology is a way of simplifying mind-boggling mathematical models of our universe. But it does not necessarily mean we live in a hologram.

Hr2: Mesh Networks, Frog Tongues, Solid Hydrogen, Science March  

March for Science organizers want to boost appreciation for research they see as under threat. Plus, scientists theorize that metallic hydrogen could be used to create superconductors and high-powered rocket propellant. And how frog saliva changes from high to low viscosity when it hits an insect.

Hr1: News Roundup, Chimeras, Astrobiology  

New advances in stem cell research will one day make it possible to grow human transplant organs in animal hosts. And astrobiologists are looking at unusual environments on Earth for clues on how to search for life elsewhere in the solar system.

Hr2: Immunizing Against Fake News, Fighting Online Extremisom, Paperfuge  

The Paperfuge is a hand-powered paper centrifuge that costs less than one dollar to produce. And a strategy for building an immunity to fake news.

Hr1: News Roundup, Jerry Brown, Brilliant Girls  

California governor Jerry Brown talks about how states can take the lead on issues like climate change and clean energy--with or without Washington, D.C. plus, internalized stereotypes that can guide career choice manifest as young as age 6.

Hr1: Special Coverage: How Will Scientific Research Fare Under President Donald Trump?  

From cabinet nominees to Congressional wishlists, a look at what could realistically change for scientists in the coming years.

Hr2: Automation, Twisted Science, Worm Indecision, Concussions  

A blood test may help athletes gauge concussion recovery. Plus, a new report looks at potential impacts of automation and artificial intelligence on jobs in a variety of industries.

Hr1:News Roundup, Uber Data, Obama Science Legacy, Asteroid Missions  

What effect has the Obama administration had on science? Plus, we discuss two new NASA missions that will investigate the metal world of asteroids.

Hr2: Malaria Vaccine Trial, Dino Eggs, Tractor Beam, Slow Science  

A 140-year-old seed study and an evolution project more than 66,000 generations old -- we take a look at long-lived experiments. Plus, A new approach to defeating malaria looks safe, but will it be effective?
