Quoted: Michio Kaku (加來 道雄 Kaku Michio) (b. January 24, 1947) is an American theoretical physicist, specializing in string field theory, and a futurist. He is a popularizer of science, host of two radio programs, and a best-selling author.
String theory is a still-developing mathematical approach to theoretical physics, whose original building blocks are one-dimensional extended objects called strings. Unlike the point particles in quantum field theories like the standard model of particle physics, strings interact in a way that is almost uniquely specified by mathematical self-consistency, forming an apparently valid quantum theory of gravity.

Quantum teleportation or entanglement-assisted teleportation is a quantum protocol by which quantum information can be transmitted utilizing a classical communication channel and an entangled pair of qubits. The sender's original qubit is destroyed in the process, as required by the no cloning theorem. The entangled pair of qubits is also separated.
Quantum teleportation does not transport energy or matter, nor does it allow communication of information at superluminal (faster than light) speed, but is useful for quantum communication and computation.

Teleportation is the movement of objects from one place to another, more or less instantaneously, without traveling through space. The concept has been widely used in science fiction. It should not be confused with quantum teleportation.

Quoted: Dr. Moira Gunn speaks with Michio Kaku, theoretical physicist and author of "Physics of the Impossible" about the improbable, and the very likely in the near future: phasers, force fields and time travel.

Those of us fanboys who work at our day jobs in the computer biz are well aware of the concept of Moore's Law which is that as time goes on more sophisticated hardware becomes cheaper to manufacture at an incremental rate. Well it seems that now some folks who develop photovoltaics (PV for short) think that they may see their technology reach a turning point by 2015 which is only seven years away:
Photovoltaic Moore's Law Will Make Solar Competitive by 2015

Quoted: Phoenix Mission: A new space explorer is waiting in the wings and ready to take center stage: the Mars lander called Phoenix. Set for launch aboard a Delta II rocket, Phoenix's assignment is to dig through the Martian soil and ice in the arctic region and use its onboard scientific instruments to analyze the samples it retrieves.
This video includes highlights from the entry, descent and landing phase as Mars Phoenix Lander touched down on the Red Planet on May 25, 2008.
