 The Athena collaboration, an
experimental group working at the CERN laboratory in Geneva, has measured
chemical reactions involving antiprotonic hydrogen, a bound object
consisting of a negatively charged antiproton paired with a
positively charged proton.

 The concept of quantum teleportation - the disembodied
complete transfer of the state of a quantum system to any other place -
was first experimentally realised between two different light beams.
Later it became also possible to transfer the properties of a stored
ion to another object of the same kind. A team of scientist headed by
Prof. Ignacio Cirac at MPQ and by Prof. Eugene Polzik at Niels Bohr
Institute in Copenhagen has now shown that the quantum states of a
light pulse can also be transferred to a macroscopic object, an
ensemble of 10 to the power of 12 atoms (Nature, 4 October 2006). This
is the first case of successful teleportation between objects of a
different nature - the one representing a "flying" medium (light), the
other a "stationary" medium (atoms). The result presented here is of
interest not only for fundamental research, but also primarily for
practical application in realising quantum computers or transmitting
coded data (quantum cryptography).

 Supercomputer simulations by
two Sandia researchers have significantly altered the theoretical
diagram universally used by scientists to understand the
characteristics of water at extreme temperatures and pressures.The new computational model also expands the known range
of water’s electrical conductivity.

 Today the Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2006 jointly to John C. Mather from the NASA Goddard Space Flight Center, Greenbelt, MD, USA, and to George F. Smoot University of California, Berkeley, CA, USA "for their discovery of the blackbody form and anisotropy of the cosmic microwave background radiation".
