In a tiny island laboratory in the northwest corner of Washington, one marine biologist is on a mission to scan every known fish species in the world. Adam Summers, a fish expert at the University of Washington, is creating 3-D models of all known species of fish. He hopes to change the way that scientists and educators look at marine anatomy.

Dave Mosher is a science reporter who's written for Scientific American, Popular Mechanics, National Geographic News and discovery.com. Throughout his career he's watched humans and robots launch into space toward a cutting edge nuclear reactor and flown over the North Pole to catch a total solar eclipse. He joins Hari Sreenivasan to share what it's like to experience that up close and personal.

Many people all over the world consume at least one cup of coffee every day. So is there a science to brewing the perfect cup of joe?

Carbon black is a material found in tires that makes the rubber stronger and gives tires their distinctive black color. But a new food waste technology may have you seeing more colorful tires in the future. Professor Katrina Cornish of The Ohio State University has been researching the use of tomato peels and egg shells as a replacement for carbon black.

From surgical simulations to a tool that helps those who suffer from PTSD, virtual reality is taking on the health care industry by storm. Carrie Shaw of Embodied Labs joins Hari Sreenivasan via Google Hangout to discuss her lab, which is at the forefront of this work.

Not many people can say they've graduated both from Columbia University and the Massachusetts Institute of Technology, have published their memoir and have flown space missions with NASA except for our guest. Today, retired astronaut Michael Massimino is a mechanical engineering professor at Columbia Engineering School. He joins Hari Sreenivasan.

First introduced in 12th century Europe, the guitar is now a ubiquitous musical instrument. And now growing in the damp forests of the Pacific Northwest may be exactly what guitar makers need for a generation of ethical and sustainable instruments. Our environmental reporting partner Earth Fix has the story.

Did you know that the pesky cockroaches we sometimes find in kitchens, sewers and basements make up less than 1 percent of all cockroach species? Researchers estimate there are as many as 20,000 roach species on the planet and less than 5,000 have been cataloged. Up next, our partner Science Friday goes into the lab with roach researchers at Rutgers University in New Jersey.

Edward Wilson, better known as E.O. Wilson is an author, esteemed biologist and conservationist. His most recent book “Half Earth: Our Planet's Fight for Life,” details his plan to help save the planet from extinction.

While some kindergarten and preschool teachers have turned to iPads in the classroom others advocate for a different kind of immersive learning, outdoor classrooms. On an island outside of Seattle, Washington, one preschool class is reconnecting with the natural world in a nontraditional setting.

Big data companies are analyzing it and scientists are mining it. And now Sunandan Chakraborty is part of a team at New York University that's using data to track the illegal wildlife trade online. He joins Hari Sreenivasan.

Engineers at the Amber lab at Caltech in California are using data to help robots walk more like humans. This research is led by Professor Aaron Ames in the Department of Mechanical and Civil Engineering. He joins Hari Sreenivasan via Google Hangout.

Science has been relying on the work of citizen scientist’s ordinary citizens who’ve aided with science research for centuries. Researcher Caren Cooper highlights the work of citizen scientists in her new book “Citizen Science, How Ordinary People are Changing the Face of Discovery”. She joins Hari Sreenivasan via Google Hangout.

A breakthrough discovery in North Carolina State University's College of Veterinary Medicine could change the way illnesses like asthma and cancer are treated. Researchers at the university discovered a compound that reduces inflammation by slowing the movement of cells into unwanted areas.

From construction workers drilling to sirens blazing, there is seemingly no escape from the cacophony of New York City streets. But now researchers from New York University and Ohio University are teaming up to curb these urban irritants with an initiative they're calling “Sounds of New York City.” Lead Investigator Juan Pablo Bello joins Hari Sreenivasan.

The presence of ice and oxygen on Europa, one of Jupiter’s four moons, has lead scientists to think that the moon could harbor extraterrestrial life. Led by astrobiologist Kevin Hand at NASA's Jet Propulsion Lab, scientists are using chilled vacuum chambers to simulate what life might be like on Europa with the hope that astronauts may one day travel there.

In today's digital age it's no surprise that many lucrative jobs require coding skills. The increased demand for skilled programmers has led to a push for schools to implement coding into their curriculum. In this segment we meet Hillary Lewandowsky from Detroit Michigan, who discovered her love of coding upon entering college and now encourages young people especially young women to code.

As young children we learn a hard truth. In the end all animals die… or do they? Next up we have the story of an ongoing science experiment and a freshwater animal that just may have found the fountain of youth.
