Sugarcane is a well-known biofuel source: Brazil has been fermenting sugarcane juice to make alcohol-based fuel for decades. Ethanol from sugarcane yields 25 percent more energy than the amount used during the production process, and reduces greenhouse gas emissions by 12 percent compared to fossil fuels.
I choose this piece of information to annotate because it was something that really stood out to me. Not only was I not aware that a type of ethanol was made from sugarcane, but I didn't know the cleanliness of it as well. The ethanol produced from sugarcane reducing greenhouse gas emissions by 12 percent is a very important aspect to consider when we think about fuel production. This could not only create a cleaner solution but a more diverse solution so we do not so as much dominance in the fuel industry.

Water immobilization is a cool thing! The simplest way to accomplish it is by freezing. But can you think of how water might be immobilized (so to speak) at temperatures above freezing, say at 50°F (10°C)? Think Jell-O and a new process that mimics caviar and you have two methods that nearly stop water in its tracks.
I learned that science and cooking is always connected. Even if we don't think about it in every day life like when water evaporates or freezes it is chemistry. But what I found most interesting that I learned is how water immobilization works, or to put it more simply the science behind Jell-O. When you add gelatin to water it traps the water molecules in place which creates the sort of liquid and solid hybrid we find with Jell-O.
