Scientists Put Squeeze On Electron Spins - SpaceDaily  In research published in today's issue of the scientific journal Physical Review Letters, Scott Crooker and Darryl Smith describe their use of a scanning optical microscope to acquire two-dimensional images of spin-polarized electrons flowing in semiconductor crystals mounted on an optical cryostat while using a miniature "cryogenic vise" to apply gentle pressure. By squeezing the crystal in a controlled manner, and without applying magnetic fields, the researchers were able to watch the electron spins rotate (or precess) as they flow through the crystal.Electron spins in semiconductors are typically manipulated by applying a magnetic field, but we've found we can do the same thing, in a controlled fashion, using the "vise". And, the resulting degree of spatial spin coherence is remarkably more robust compared to the spin precession induced by a magnetic field."     
Animator Nick Park with claymation model of Wallace, from Wallace And Gromit 'Teleporting' over the internet  - BBC  Computer scientists in the US are developing a system which would allow people to "teleport" a solid 3D recreation of themselves over the internet. Professors Todd Mowry and Seth Goldstein of Carnegie Mellon University in Pennsylvania think that, within a human generation, we might be able to replicate three-dimensional objects out of a mass of material made up of small synthetic "atoms". Cameras would capture the movement of an object or person and then this data would be fed to the atoms, which would then assemble themselves to make up an exact likeness of the object.

New model 'permits time travel'  - BBC  If you went back in time and met your teenage parents, you could not split them up and prevent your birth - even if you wanted to, a new quantum model has stated. In other words, you can pop back in time and have a look around, but you cannot do anything that will alter the present you left behind. The new model, which uses the laws of quantum mechanics, gets rid of the famous paradox surrounding time travel. The main headache stems from the idea that if you went back in time you could, theoretically, do something to change the present; and that possibility messes up the whole theory of time travel. either time travel is not possible, or something is actually acting to prevent any backward movement from changing the present. Einstein's general theory of relativity leads some physicists to suspect the latter.
