Our expanding waistlines result from the  competition between our modern diet and our ancestral genes.  The book Newton’s Football (Random House) spells in out:

Cheap and easy access to calories is a very recent development in the human condition. The hunting and gathering that early man did was a boom-or-bust business. One day there’d be a feast in the form of ripe fruits and vegetables or a freshly killed ox. And there were, of course, no Ziploc bags or Sub-Zero refrigerators in which to store the leftovers.

When the harvest was over and the hunters hit a dry spell, it was famine time. Attempts to store food were generally unsuccessful, and even when it did work, it still required an early human to defend the food against those who’d steal it, human or otherwise.

Storing excess calories as fat was an elegant solution to these problems.

“Fat is the best defense against a rainy day, and throughout human history there were lots of rainy days,” explains David Katz, founding director of the Yale Prevention Research Center.

Additionally, there is a new ingredient in our diet that our ancestors rarely enjoyed, and that is processed sugar.  Sugar is surprisingly prevalent in our modern diets and is found in bread and crackers and salad dressing and tomato sauce. And, that’s more calories to burn.

Sugar in moderation is a good thing and serves as a fuel for our bodies, but if we don’t use sugar, it gets stored. “It’s subject to the laws of thermodynamics,” says Katz. “If you don’t burn it, the body will store it as an excess of calories.”

As one can see, fat was a Stone Age solution for a rainy day when there wasn’t any food. Unfortunately, in our modern day, that rainy day never comes.

So, blame those extra pounds on your ancestors.

There’s no papering over the impact of origami in technology.

What do pizza boxes, paper bags, and fancy napkins have in common? Well, you might have guessed it — origami.

Origami, which means “paper folding,” is everywhere. While some of the oldest pieces of origami have been found in ancient China and origami’s deepest roots are in ancient Japan, origami makes an impact in today’s technology too.

One of the most important uses of origami today is in airbags. Airbags are doughnut-shape nylon bags that are deployed in a fraction of a second during a car collision. Airbags lie flat inside of the steering wheel. So, engineers needed to find the way to fold an airbag so it will store flat and expand out quickly. They consulted origami artist Robert Lang for the folding recipes. He found the origami folds for making a box with lots of corners was the solution that was needed.

Origami doesn’t stop there. The National Science Foundation, one of the government’s largest funding sources for research, has funded 13 grants last year to use origami in industry. Origami is being applied to foldable forceps to expanding solar panels to deployable antennas.

Interestingly, other cultures also have a history of folded paper. There are elaborate folded patterns in Europe and folded paper in Mesoamerica going back over a thousand years.

Today, schools are using origami in STEAM education to improve students’ skills. Origami has been found to increase thinking skills, improve geometry learning, and enhance problem solving.

Origami is used in nature. Bugs fold wings with origami patterns; leaf buds have patterns that are similar to Japanese fans. Even molecules are arranged like origami structures.

So, get a piece of paper out and make some folds. Be connected by using this technique that has made impact in so many ways and for so long.
