SciWorks Radio - Body On A Chip

Today we’ll  talk about printing body parts.  I’m not talking about antics in the copy room. I mean bio-printing three dimensional human organs for medical research.

There are several types of 3D printers, but  the generic model for this particular type involves a nozzle that squirts out a building material like an ink. Mounted in a frame, it moves side to side as well as up and down. This allows for travel to any point within the printer’s range; “printing” material layer by layer. The result is an accurate translation of a digital computer file into a solid three dimensional object.

Triad Geology

Learn about the unique geology of the Triad in this first episode of SciWorks Radio.

From a geologic perspective, we don’t usually think about the North Carolina Piedmont as being very exciting. There are no tall mountains or volcanoes right nearby. But what if I told you that much of the area was once dominated by towering mountains and active volcanoes? In fact most of the piedmont was made up of a series of volcanic islands, or “island Arcs” much like Japan or Indonesia today. These separated themselves from the early continents, eventually collided and were squeezed together as the supercontinent “Pangea” was being formed. This same thing happened up and down most of the East Coast of the United States. Any time you find actual granite exposed at the surface, it was once part of a magma chamber located deep within the earth, likely feeding the region’s volcanos that were formed in these collisions. The Greensboro area has a lot this.

Getting There from Here: Local Writer Publishes Book About GPS

We live in a world dependent on the Global Positioning System, or GPS.  It powers our navigation systems, smart phone apps and lets us here at WFDD synch perfectly with NPR programs like Morning Edition and All things Considered.  Roger Easton was one of the key scientists behind GPS.  A few years ago, his son Richard began writing a book about his father's work.  Around the same time, Kernersville writer Eric Frazier's curiosity was picqued when his daughter bought a GPS unit and stopped calling him for directions.
