Slow Neutrinos?

Read time: 1 min

The "faster-than-light neutrino" result was probably in error. OPERA admits that faster than light Neutrino measurement may have been an error.

The OPERA’s official statement reads in full:

“The OPERA Collaboration, by continuing its campaign of verifications on the neutrino velocity measurement, has identified two issues that could significantly affect the reported result. The first one is linked to the oscillator used to produce the events time-stamps in between the GPS synchronizations. The second point is related to the connection of the optical fiber bringing the external GPS signal to the OPERA master clock.
These two issues can modify the neutrino time of flight in opposite directions. While continuing our investigations, in order to unambiguously quantify the effect on the observed result, the Collaboration is looking forward to performing a new measurement of the neutrino velocity as soon as a new bunched beam will be available in 2012. An extensive report on the above mentioned verifications and results will be shortly made available to the scientific committees and agencies.”

Molecular machines, an already written future

In a world in which chemists assemble devices and machines billion times smaller than the usual ones, it is possible to develop systems similar to those created by nature within cells. The intricate arrangement of cellular organelles and enzymatic systems, muscle contraction, intracellular transport and ATP synthesis are examples of biological motors. For chemists this is a real challenge; to design active nanostructures that can operate as molecular machines, to increase our understanding of biological nanomotors and to construct a new generation of devices capable, for
