Slow Neutrinos?

The "faster-than-light neutrino" result was probably an 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.”

How many B antigens should a good influenza vaccine have?

The vaccine against seasonal influenza is called trivalent, because it contains viruses representing three influenza strains: one A/H1N1, one A/H3N2, and one B. the single B-lineage antigen included is the one that is predicted to circulate in the related season. However, this means that some mismatch between the B antigen in the vaccine and the B antigen actually circulating may occur, this being a problem since cross-protection by immunization against the other lineage is expected to be low.
