In 1900, most people accepted the earth to be about 6,000 years old.  By 1955, that estimate shot up a bit, to about 4.5 billion years.  The change was largely due to Arthur Holmes's obsession to pin down the age of our planet, and incidentally shape the science of geology as we know it.  Todd talks with author Cherry Lewis about Arthur Holmes.  Her book is "The Dating Game: One Man's Search for the Age of the Earth".

The "Chicago Daily Tribune" has a new look.  Changes include easier to read fonts, and headlines that quickly get to the point of the story. Director of Consumer Sales and Marketing Carrie Hoye talks with Todd about the changes.

Todd talks with music critic Patrick Beach about the music festival "South By Southwest".  Beach discusses who attends the festival, and how the city of Austin deals with the people and crowds.

Researchers at the National Geophysical Data Center are measuring the amount of artificial light emitted into the night sky by looking at the light reflected back onto the ground.  Chris Elvidge is from the Office of the Director at the Center, and tells Todd about how satellite data is used to take the measurements, and what this says about light pollution in certain areas of the world.
