Enhanced geothermal systems are a new type of geothermal power than can be used where naturally occurring geothermal systems do not exist. With enhanced geothermal systems, an injection well is drilled into dry rock. Water is forced into the injection well, which widens the ground fractures below. This process is known as 'hydraulic stimulation'. Water travels through fractures in the rock and becomes hot. This water then travels up a production well. The steam from this water is then used to drive a turbine and thus produce electricity.

Scientists studying the rotation of the Earth have long known that our planet doesn't have a perfect spin. Most believe this is due to the different types of materials that make up the core, mantle and crust, which all have different rates of spin causing inherent friction. Most models researchers have developed however agree that in order for the planet to wobble the way it does, the mantle would have to respond to the magnetic tug of the core. The problem with this though, is that the mantle is made mostly of rock, not metal, which means it’s not supposed to be conductive.

An ice core from the Antarctic has given an NSF-funded research team a glimpse into the very distant past. The continuous core sample provides details on how the Earth's climate and atmosphere changed long ago, and gives clues about variations in ice levels. The oldest ice from the bottom of the core may be up to 100,000 years old.
