The Methanol Economy Featuring Surya Prakash
Could a simple molecule known as methanol become a key energy source for the post-fossil fuel era? 1994 Nobel Prize in Chemistry winner George Olah, Ph.D., and Surya Prakash, Ph.D., think so. Olah and Prakash recently won a $1 million prize from the Israeli government for their research on a promising alternative fuel concept, known as the “methanol economy.” In our latest video, Surya Prakash gives us a rundown of the potentials that the methanol economy bolsters, and shows us why this concept offers such a promising future.

SCI CODE - Sugarless Gum vs Cavities
Previously we learned that there are bacteria in our mouths that eat sugar and poop out acid. The acid can reduce the pH balance of our mouths.
pH is the measure of a solution’s acidity or basicity. Water is neutral- pH 7. And anything lower is acidic.
If the pH in our mouths drops below 5.5, acids can start to wreck your teeth. However, studies show that chewing sugarless gum after eating can help reduce acid levels.
As you chew the gum, you begin to salivate. The increased flow of saliva washes away and neutralizes the acid-turds of those sugar hungry microbes. The increased saliva also brings in calcium and phosphates to strengthen tooth enamel.
While chewing sugarless gum may be effective in laying the smack down on tooth decay, you still have to brush and floss regularly and properly for a healthy smile. No exceptions!
For more information and a list of approved sugar-free gums, check out the American Dental Association.
The Direct Methanol Fuel Cell
Surya Prakash, Ph.D. and Nobel Laureate George Olah, Ph. D. are working on an alternative fuel concept known as the methanol economy. Methanol offers a large scope of potential applications ranging from use in combustion engines to being used to produce products such as plastics and solvents. Another intriguing potential of methanol is its use as a storable fuel source. In this video, Surya Prakash explains what a direct methanol fuel cell is, and talks about its potential applications.

Why Does Alka-Seltzer Fizz?
The fizzing you see when you drop an Alka-Seltzer tablet in water is the same sort of fizzing that you see from baking powder. This reaction is caused by an acid reacting with a base. Check out this BrainStuff episode to learn more.

What makes us feel good about our work?
What motivates us to work? Contrary to conventional wisdom, it isn’t just money. But it’s not exactly joy either. It seems that most of us thrive by making constant progress and feeling a sense of purpose. Behavioral economist Dan Ariely presents two eye-opening experiments that reveal our unexpected and nuanced attitudes toward meaning in our work. (Filmed at TEDxRiodelaPlata.)
