Researchers have developed brain implants that allowed rats to communicate by thought alone, even from separate continents. The researchers implanted microelectrodes 1/100th the width of a hair into the brains of rats.

Placed in separate cages, these rats were able to solve puzzles, they found.

One rat was able to interpret the other's actions and intentions even when they couldn't see or hear each other, Fox News reported.

The same experiment worked when the rats were thousands of miles apart with one in Brazil and another in North Carolina.
