Toucans are tropical birds found in Central and South America. They are best known for their enormous, brilliantly colored bills. These beaks perform several functions, but new research confirms that they accomplish yet another essential job.

They helped underpin belief in vast ages and had largely gone unchallenged. But certain decay rates apparently aren’t as stable as some would hope.

The Internet search engines Google and Yahoo! have massive server farms that are all interconnected in a network configuration called “cloud computing.” These systems are engineered with fault tolerance features so that if one server breaks down it does not impair the operation of the whole, since another server has all the data ready to go in no time.

Massive schools of cod fish once dominated regions of the North Atlantic Ocean.
