Source: news.nationalgeographic.comHow many legs does a kangaroo have? The correct answer, according to new research, is five. A study in this week's Biology Letters says that a walking kangaroo propels itself with its tail, essentially transforming the appendage into a fifth "leg."
The study found that the tail of a walking kangaroo works as hard as the leg of a comparably sized human strolling at the same speed. No other animal is known to employ its tail this way, and the study's authors speculate that use of the tail as a leg evolved to make the hop—a classic and unique kangaroo maneuver—more efficient.

TIL... about these 5 cool new gadgets. The translator seems like it would be really useful - and just a little bit Star Trekky (but that could just be me!) The tiny quad-copter drone would be my next favourite.
I wonder if it would discourage people from learning foreign languages though?
