Things I learned lately 28 Feb

• Researchers are figuring out how to make edible fat as a replacement for butter and oil out of insects. Insect fat contains lauric acid, which provides positive nutritional attributes since it is more digestible than butter. Moreover, lauric acid has an antibacterial, antimicrobial and antimycotic effect.
• In Japan, you can get mayonnaise in solid form in slices, like cheese singles.
• The estimated number of birds killed in North America each year by wind turbines: @300,000. The estimated number of birds killed in the US each year by cats: 1.4 to 3.7 billion. While that seems to put things into perspective, it omits a critical fact. Cats don't kill large endangered birds like owls or eagles. But wind turbines have been known to.
• This TED talk sheds some light on the real cost and drawbacks of the most popular renewable energy sources and offers a surprising solution that is more efficient, costs less, doesn't kill any wildlife, and is much less harmful to the environment. 
• Paper-based currency doesn't last long, so the U.S. Treasury Department keeps busy disposing of damaged currency and printing new stock. Every day, the presses print 25 million notes worth approximately 560 million dollars.
• The Boeing 737 was first introduced in 1967.
• The Hoover Dam construction project, started in 1931, was the first construction project in the world where the workers were required to wear hard hats.
• The actor inside the alien suit in the 1979 sci-fi classic Alien, took Tai Chi and mime lessons in order to give the alien the slow, smooth, and deliberate movements that thoroughly terrified audiences.
