Journalist Dave Levitan provides a guide to cut through the deceptive arguments politicians use to undermine scientific evidence. Plus simulating Mars missions, and news from Enceladus about the moons hydrothermal activity.

Hr2: Giant Virus, Radio Astronomy, SETI, Lyme  

Giant viruses evolved from smaller viruses that picked up genes from other organisms, according to a new study. Plus, a look at the search for extraterrestrial intelligence, and the challenges of listening to the stars from a planet filled with radio transmissions. And as incidence of Lyme disease soars, scientists look for answers.

Hr1: News Roundup, Noise, Michael Mann, Mars Wheels, Splashing  

Michael Mann discusses his participation on the latest House Committee on Science hearing on climate change. Plus a visit to the playground where Mars rovers are put through their paces, and how one researcher peers deep inside sneezes to answer questions about disease transmission.

Hr2: Engineering New Ideas, Bionic Arm, Robotic Prospecting  

If humans someday colonize the moon and Mars, robotic prospectors and miners will be among the first to arrive, manufacturing fuel, water, and other essentials. Plus technology like 3D printing is expanding what prosthetic limbs can do, and who can wear them.

Hr1: News Roundup, Dino Family Tree, What-If Physics, Impact Glass  

Geologist Peter Schultz uses a high-velocity gun to test his hypothesis that asteroid impacts could preserve signs of ancient life. Plus, what would happen if you stuck your hand in a particle accelerator or jumped off of the Space Station?

Hr2: Wildflowers and Bees, Infinity and Beyond  

The wildflower explosion in the southern California desert provides plentiful food to wild bees. In this springtime special, we talk about which wildflowers—and pollinators—to spot this season, and how to log your observations at Plus, mathematician Eugenia Cheng explores infinity.

Hr1: News Roundup, Residents Hours, BP Oil Spill, Gerrymandering  

A play explores the loss of human and animal life after the Deepwater Horizon exploded in 2010. Plus, can the shape of a congressional district tell us everything we need to know about its fairness?

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.
