The Mpemba Effect is a special phenomenon where hot water freezes faster than cold water. The discovery of this effect was made by a high school student named Mpemba in Tanzania, Africa in 1969. He noticed this phenomenon while making ice cream and was curious enough to make note of it. His teachers did not believe it was possible, and it took several years until university professors finally accepted his discovery.

 

Despite its name and hopping gait, the kangaroo rat actually has more in common with a camel than with its much larger marsupial namesake.

The kangaroo rat is a rodent, but it is unlike any other rodent on Earth: it is able to survive in the desert with virtually no drinking water. The camel is the only other mammal that can match this feat, and yet the kangaroo rat looks nothing like the ‘ship of the desert’.

 

The harmful effects of global warming on daily life are already showing up, and within a couple of decades hundreds of millions of people won't have enough water, top scientists will say next month at a meeting in Belgium.

At the same time, tens of millions of people will be flooded out of their homes each year as the Earth reels from rising temperatures and sea levels, according to portions of a draft of an international scientific report obtained by The Associated Press.
