\nJocelyn Bell Burnell (b. 1943) is an astrophysicist from Northern\nIreland, who was the first to discover radio pulsars. Despite the fact that it\nwas her research that led to the first observation and analysis of the pulsars,\nit was her supervisor, Antony Hewish, who received the 1974 Nobel Prize in\nPhysics for the breakthrough discovery.
\nGrowing up in Northern Ireland, she was only\nallowed to study science at school after her parents and others protested\nagainst the exclusion of female students from such subjects. She obtained her\nPhD from the University of Cambridge, and went on to become the President of\nthe Royal Astronomical Society and of the Institute of Physics. In 2014 she\nbecame President of the Royal Society of Edinburgh, the first woman to hold the\nposition.
\nShe was awarded the Special Breakthrough Prize in Fundamental Physics in 2018, and used all of the £2.3 million to help female, minority and refugee students become physics researchers.

\nAs epidemiologist Ellie Murray explains, it’s almost certainly just “lead time bias.”
\nThat’s when you test more people, including presymptomatic people, and thus discover the disease earlier than before.

\nThat means we learn people are sick earlier, which means that the time between detection and death gets longer - not because people are surviving longer from the onset of symptoms, but because we’re detecting sick people before they exhibit symptoms.
\nLead-time bias emerges whenever we ramp up testing: routine mammograms and colonoscopies appeared to change the course of related cancers, but what was really going on was earlier, presymptomatic identification of cancers.
\nAnd while it’s true that we measured earlier cases from the first symptoms, we didn’t know what some symptoms were (loss of smell, for example) and we relied on self-reporting by gravely ill people, which isn’t as good as actual tests.
\nThat’s called “recall bias.” Sometimes we’d ask family members, who only knew about the symptoms that were severe enough to warrant mentioning (“proxy respondent bias”).
\nBottom line: “When you start identifying people at earlier stages of a disease, it looks like they survive longer (or have the disease longer) compared to when you identify based on severe symptoms.” -Ellie Murray
