The study found that the brain's electrical activity for listened music and imagined or expected music was the same except for being of opposite voltage. When the listened music matched the expected music in the brain, the positive and negative signals cancel each other out.

Faster Than Wind Travel

A former aerospace engineer turned YouTuber Rick Cavellero designed a land yacht that harnesses the power of the wind to propel itself faster than said wind.

Researchers at Rice Unievrsity have observed networks of fungi demostrate economic market principles of Walrusian equilibrium when they negotiate the exchange of carbon & nutrients with host organisms. Manipulating these interactions may allow the organisms to sequester even more carbon, on top of the 5 billion tonnes of carbon they already secure per year.
