Of all of the paths toward molecular manufacturing, structural DNA nanotechnology seems to provide the most frequent and photogenic advances. By re-engineering the Holliday junction, the basic cross-over structure adapted to build complex structures from DNA, Prof. Hao Yan and his colleagues has been able to construct a variety of new wire frame and mesh structures. A hat tip to ScienceDaily for reprinting this Arizona State University news release “ ASU scientists develop innovative twists to DNA nanotechnology “: In a new discovery that represents a major step in solving a critical design challenge, Arizona State University Professor Hao Yan has led a research team to produce a wide variety of 2-D and 3-D structures that push the boundaries of the burgeoning field of DNA nanotechnology.

Posted on behalf of Zeeya Merali. And the award for ‘best physicist’ goes to…Alexander Polyakov, of Princeton University in New Jersey. Polyakov was yesterday named the winner of 2013’s whopping US$3-million Fundamental Physics Prize for his early work on developing some of the mathematics behind the quantum-mechanical theory of fields that today underpins the standard model of particle physics.
Quantum teleportation , or entanglement-assisted teleportation , is a process by which a qubit (the basic unit of quantum information) can be transmitted exactly (in principle) from one location to another, without the qubit being transmitted through the intervening space. It is useful for quantum information processing . However, it does not immediately transmit classical information , and therefore cannot be used for communication at superluminal (faster than light) speed. Quantum teleportation is unrelated to the common term teleportation – it does not transport the system itself, and does not concern rearranging particles to copy the form of an object.
Teleportation is the transfer of matter from one point to another without traversing the physical space between them. [ edit ] Etymology The word teleportation was coined in 1931 [ 1 ] [ 2 ] by American writer Charles Fort to describe the strange disappearances and appearances of anomalies , which he suggested may be connected. He joined the Greek prefix tele- (meaning "distant") to the Latin verb portare (meaning "to carry"). Fort's first formal use of the word was in the second chapter of his 1931 book, Lo! : "Mostly in this book I shall specialize upon indications that there exists a transportory force that I shall call Teleportation ."
Editor's note: This is the third part of Crave's four-part series on Ecuador's attempt to become Latin America's hub for science, technology, and innovation. Read part 1, " Plotting the next Silicon Valley -- you'll never guess where ," and part 2, " New Silicon Valley in the Andes: Promise and paradox ." QUITO, Ecuador--Right now, I'm one of the final things standing between Ramiro Moncayo and a vacation he's been waiting to take for years. It's just a few days before Christmas, and needless to say, he is very excited about the couple of days he is about to spend with his family on a holiday getaway.
