Plural: neutrinos.

A neutral subatomic particle with a mass close to zero and half-integral spin, which rarely reacts with normal matter. Three kinds of neutrinos are known, associated with the electron, muon, and tau particles.

not "no-one"

Capitals for specific titles: Nobel Prize in Physics, Nobel Prize in Literature, Nobel Peace Prize, etc.

In the preamble to its Staff Rules and Regulations [CERN NICE Login required], CERN reaffirms equality of treatment between people as one of the basic principles of its personnel policy and does not discriminate between members of its personnel, in particular on account of race, religion, sex or sexual orientation. Authors of CERN texts must take care to avoid any discriminatory language that could cause offence, exclude certain groups of people or reinforce stereotypes.

It is a (persistent) myth that "none" has to take a singular verb: plural is acceptable and often sounds more natural, e.g. "none of the current squad are good enough to play in the Premiership", "none of the issues have been resolved"

Joe Bloggs (1933 - 2008)

The strapline should contain a description of the person based on highlights from their career:

Theorist who revolutionised random-sets algebra and paved the way for supersymmetric theories of time

The obituary should be respectful and measured. Do not be defamatory, but equally do not exaggerate the person's contribution. Avoid superlatives.

With an "s". 

Except when referring to CERN – "The Organization" – which takes a "z" and an upper case "O". (This is because the name was spelled with a "z" in the CERN convention, so the "z" is part of the official name).

Remember, follow British English for spelling.
