Nurse's mother went from London toNorwich and lived with relatives while awaiting Paul's birth (at the age of 18)[9] in order to hideillegitimacy. For the rest of their lives, his maternal grandmother pretended to be his mother, and his mother pretended to be his sister.[10]
Nurse did not know that his "sister" was in fact his mother until he was in his 50s. His "parents" had both already died and his "sister" Miriam, eighteen years his senior, had died early ofmultiple sclerosis. His application for agreen card for US residency while president ofRockefeller University was, to his surprise, rejected, despite him being aNobel Prize winner, president of a university and a knight; this was because he had submitted a short-formUK birth certificate which did not name his parents. When he applied for a full birth certificate he discovered the truth, to his astonishment.[9][12]Professor Turi King traced his father for him in 2023.[13]
Working in fission yeast, Nurse identified the gene cdc2, which controls the transition from G1 to S, when the cell grows in preparation for the duplication of DNA, and G2 to M, when the cell divides. With his postdocMelanie Lee, Nurse also found the corresponding gene, CDK1, in humans. These genes stop and start cyclin dependent kinase (CDK) by adding or removing phosphate groups.[19]
Nurse has said good scientists must have passion "to know the answer to the questions" that interest them, along with good technical ability, and a set of attitudes including mental honesty, self-criticism, open-mindedness and scepticism.[22]
Nurse married Anne Teresa (née Talbott) in 1971; they have two daughters – Sarah, who works forITV, and Emily,[45] a physicist based atUniversity College London andCERN.[46][1] He describes himself as a sceptical agnostic.[14]
Nurse has been a member of theLabour Party for nearly 40 years and is a patron ofScientists for Labour, asocialist society affiliated to them.[47] In September 2020, he was a co-author on a letter inNature alongside the former prime ministerGordon Brown highlighting the importance ofEU funding in the fight againstCOVID-19.[48]
As an undergraduate student at Birmingham, Nurse soldSocialist Worker, and participated in an occupation of the vice-chancellor's office.[46][49] As a graduate student at East Anglia he continued to sellSocialist Worker, and was sympathetic to theInternational Socialist Tendency but never formally joined the movement.[50]
One problem, Nurse said, was "treating scientific discussion as if it were political debate," using rhetorical tricks rather than logic. Another was the state of science teaching in the schools, which does not teach citizens how to discuss science – particularly in religious schools, even in the United Kingdom.[51] Nurse has written that "we need to emphasise why the scientific process is such a reliable generator of knowledge with its respect for evidence, for scepticism, for consistency of approach, for the constant testing of ideas."[51] Furthermore, Nurse feels that scientific leaders "have a responsibility to expose the bunkum". They should take on politicians, and expose nonsense during elections.[51]
In August 2014, Nurse was one of 200 public figures who were signatories to a letter toThe Guardian expressing their hope that Scotland would vote to remain part of the United Kingdom in September'sreferendum on that issue.[52]
Nurse believes that scientists should speak out about science in public affairs and challenge politicians who support policies based onpseudoscience.[53]
