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.”

President Trump reshapes US research landscape

trump

Con una serie di ordini esecutivi, Donald Trump smantella le politiche climatiche di Biden e ritira gli Stati Uniti dall'accordo di Parigi. Le agenzie federali scientifiche (EPA, NIH, CDC, FDA, NASA) vengono ristrutturate con nuove nomine orientate alla deregolamentazione. Vengono congelate le assunzioni federali, mentre la revisione delle collaborazioni internazionali potrebbe ridefinire il ruolo USA nella ricerca globale. Immagine: Donald Trump.

20 January 2025 marks a turning point in US science policy, with a series of executive orders drastically redefining the role of federal science and research agencies. A detailed analysis of the documents reveals an approach that fundamentally changes the basis of US climate, energy and biomedical research policy.

This comprehensive list shows the scope and breadth of the first day's interventions, which touch virtually every aspect of the federal government, from foreign policy to national security, from energy to immigration, from administrative reform to social policy.
