Understanding the attraction of salty and sweet

Chocolate-covered pretzels, caramel popcorn, peanut butter and jelly, pineapple pizza, salt on watermelon (yes, it’s a thing) - sweet and salty is a pairing made in food heaven. The combination is found nearly everywhere to the point where, on the surface, the two make perfect sense, but think it over and it’s not necessarily obvious why these two flavors work so well.

Why don’t these two flavors clash? Scientists from Monell Chemical Senses Center in Philadelphia and Utah State University set out to answer this very question.

No compass necessary

As the snow (hopefully) stops falling and the weather takes a turn for the better, the snowbirds who made their annual trek south at the start of winter begin to return back north. They use planes, trains and cars allowing their navigation systems, maps, conductors and pilots to lead the way.

Similarly, months ago many real birds began their annual journey south and will soon return back north, but these birds don’t have GPS or a map to show them the way. How exactly do they know which way to fly?

Questions about battery life answered

We are a society always seeking. No, I’m not referring to our search for purpose, a career or love. I’m talking about the constant search for outlets to charge our electronic devices. We charge our phones, tablets, etc. hoping the battery lasts the same amount of time as the day of purchase, only to be sent off running for the nearest outlet to charge yet again much too soon.
