This week we dive into the world of CRISPR-Cas9 and gene editing with a hopefully easy to understand overview of the basics. What is CRISPR, what can and might it do, what are the concerns and roadblocks.

Also, new nano metal techniques for improving hardness, and the Air Force X37 sets a record.

This week I have a chat with guest Jamey Racer, radiographer and teacher. We talk about the past, present, and future of radiology and medical imaging. Types of scans, radiation exposure, and the changes that computers and artificial intelligence are bringing to the work.

This week we explore the newest techniques in growing animal-free meat and other products using cell cultures.

Also, 3d printed houses and exploring Titan in a flying machine

In the continuing food series this week we talk about vertical, urban, and indoor farming, and 3d printed food.

Also, GMO nutrition, fast food self-service, and NASA's next solar probe.

This week I talk about a controversial topic, genetically modified organisms and gene editing, and how these aspects of modern science can feed us far into the future. I will have links to the science on the show's web page, for my part I focus on the basics and the benefits of GMOs and gene editing for food production.

Also, metamaterial news, new planets, and the Hubble Constant

This week I chat with the Farm Babe, Michelle Miller, about modern farming, farm technology, and myths about farmers (you know, the scant handful of people who feed us all).

Also, Bill Gates on taxing robots, and the Icarus Project for interstellar travel.

This week I begin a run of shows on the future of food, food production, technology, and farming. Everything from self-driving tractors, drones, lab grown meat, vertical farming, and GMO seeds is on the table for discussion.

Also, robots in China and NASA's Europa mission

This week I have another long chat with science fiction author A.C. Hachem (achachem.com) about his recently released book Dawn Of Legaia (dawnoflegaia.com). We also touch on creativity and the process, the technology in his book (including AI, androids, and artificial gravity), the near future society he's imagined, comic cons, and then we nerd out about movies and video games for a while.

This week I ramble about the need for level-headed communication for a functional society, and ponder why it's so hard to do, including science communication.

Also, lots of medical news from Earth and space about stem cells and genetics.

This week I offer an overview of scientific consensus - what it is, and why we should accept it.

And in the news: Vantablack, and mud on Mars
