Slower than Light 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.”

Neanderthal genes made Covid more severe

The Origin study from the Mario Negri Institute has identified genetic variants from Neanderthals in the DNA of those who had the most severe form of the disease.

A small group of genes that we inherited from the Neanderthal man - and from his romantic relationships with our sapiens ancestors - exposes us today to the risk of developing severe Covid. This is the unique conclusion of the Origin study by the Mario Negri Institute, presented yesterday in Milan and published in the journal iScience.
