What makes you you? Is the self somewhere in the body or the brain? If you downloaded your brain into a new body, would it be you? ANSWER ME (whatever 'me' is)

A woman has a condition that makes her see dragons wherever she goes. Anthony and Jeff discuss perception and reality, and if we know what we see is real.

Every Autumn, falling leaves create hazards for the railways. Trains compress the debris by running over it, and the resulting surface becomes slick and unsafe. The solution? Lasers! One Dutch company has developed a way to blast the rails clean with high-tech lasers mounted to the front of the trains - which, of course, inspires Jeff and Anthony to pitch their new action/adventure trilogy, Laser Trains!

Adrian David Cheok, the founder and director of the Mixed Reality Lab in Singapore, is attempting to record odors digitally, and recreate them without the use of chemicals. While a breakthrough in the area is still a long way off, the idea of digital smells has Jeff and Anthony wondering what this technology could possibly be used for, and, moreoever, what working in a place called the Mixed Reality Lab" might be like.

Scientists at the University of Rochester Medical Center in New York have successfully implanted human glial cells into the brains of mice to shocking result. Not only were the cells not rejected, but the human cells completely dominated the mouse brain cells. More incredibly, this led to mice which demonstrated a much higher capacity for memory and cognitive skill...

A New Yorker article all about passwords has Jeff musing on what Anthony's passwords mean about him. It is a secret people tell themselves every time they log on to something, so what are the most common topics that appear in passwords? What are the smartest passwords? How can they can used to hack your life?

These are some of the most horrible organisms in the natural world. This episode is not recommended for sensitive listeners.

New anaysis suggests that the bronze computing device known as the Antikythera, discovered at the bottom of the Aegean Sea in 1901 is even older than previously thought. In fact, this computer dates back to 200 BC and represents a incredible feat of pre-historic human engineering. Anthony and Jeff marvel at a people that could devise such a thing, and rail at the Dark Ages for stealing away so many awesome advancements.

According to quantum physics, Planck's Constant is the smallest unit of measure in the universe, beyond which nothing can be further divided. Scientists at the Fermilab are building a Holographic Interferometer, or Holometer, with which they intend to test this theory. If true, it could mean that our entire dimension is a hologram, projected into 3D space like a pixelized image on your computer screen...
