Ever since Thomas Jefferson championed the “yeoman farmer,” Americans across the political spectrum have romanticized small businesses. Politicians tout Mom-and-Pop companies as the backbone of the economy. But, if you run the numbers, small businesses don’t live up to the hype, according to economist Robert D. Atkinson, co-author of the book “Big is Beautiful: Debunking the Myth of Small Business.” Atkinson says that we should take a size-neutral approach to regulating businesses.

We rely on precision in every part of our lives. We take for granted the fact that if our car breaks down, we can buy a replacement part, instead of a whole new car. But there was a time before standardized car parts, standardized batteries, and standardized shoe sizes. In his new book “The Perfectionists,” author and journalist Simon Winchester set out to learn how the concept of precision came to be, and how it changed the world.

Choosing Friday night plans. Deciding what to wear to work. Selecting a new Netflix show to binge-watch. People are influenced by the tastes and opinions of their friends, and vice versa. But that doesn’t mean you’re a carbon copy of your social network— or does it? We talk with Carolyn Parkinson, an assistant professor of social psychology at UCLA, about why our brains might be more similar that we think.

We’re always so concerned about how to do something, but we don't always consider when we should do it. When should we start a new project? When should we take a nap? We talk to author Daniel Pink about why timing is everything.

Even though beards are currently in style, there was a time when being clean shaven was the way to go. We take a look at the man who revolutionized the shaving industry.  

Plus, if it seems like food allergies are on the rise, they are. One in every 13 children in America has some sort of food allergy, which marks a huge spike over the last few decades. We look at what could be causing the allergy increase and what’s being done to combat it. 

Finally, killing rats may seem like the best way to deal with them. But, in fact, it’s probably not our best option when it comes to pest control. We find out what is.

Does it matter when you go in for an operation? When a jury hears your case? What year you're born in? The answer in all three of these cases: yes. Dan Pink took a deep dive into the science behind how timing affects our lives. He's author of the new book, "When: The Scientific Secrets of Perfect Timing."

If you're the type of person who shaves, you've probably used a disposable razor at least once. But where did this seemingly ubiquitous part of American life come from? It all goes back to the late 19th century, and a man with the absolutely incredible name of King Camp Gillette.

Did you ever trade lunches at school when you were a kid? Maybe you gave away your peanut butter sandwich in exchange for some chocolate pudding. With rampant food allergies, a trade like that probably wouldn't happen today. And while schools and other organizations are very aware of the increased number of people who have allergies, we know little about what causes them.  

We talk to Dr. Wayne Shreffler, the director of the Food Allergy Center at Massachusetts General Hospital and Dr. Katie Allen, the Group Leader of Gastro and Food Allergy at Murdoch Children's Research Institute in Melbourne, about the rise of food allergies, how to prevent them, and treatments that are in the pipeline.

Rats: The bane of any city-dweller’s existence. We spend millions of dollars each year trying to kill these pests, putting out poison and traps. But new research poses the question: Should we be killing rats at all? Innovation Hub producer Marc Filippino reports on what could be a surprising new solution to rat control.

First, we talk with Kurt Beyer about the Queen of Software, Grace Hopper, and how her new ideas changed the tech world forever.

Next, we give you Kisses. And Reese’s. And Kit Kats. We take a look at how Milton Hershey built one of the biggest chocolate empires the world has ever seen.

Then, we’re all wondering when we can hop into our self-driving cars and watch Netflix on our way to work. But Rodney Brooks says: don’t expect it to happen tomorrow.

She’s been called “the first lady of software.” A conference named after her attracted over 18,000 attendees last year. She had her own Google doodle. She was even on Letterman.

It’s fair to say that Grace Hopper is one of the most celebrated coders ever. But, behind all the accolades, who was she? And how exactly did she change technology? We talk with Kurt Beyer, author of “Grace Hopper and the Invention of the Information Age.”
