    In many regions of the world, HPV and its association with cervical cancer is a well-known but rarely considered issue, after the rollout of the HPV vaccine in the late 2000s. However, while this rollout significantly impacted cervical cancer rates where it was implemented, it was not universal and in many areas of the world HPV induced cervical cancer remains a critical issue.Cervical cancer is the leading cause of death for people with a cervix living in poverty in low-resource regions and on the continent of Africa, it is estimated that in 2020 as many people with a cervix died of cervical cancer as COVID-19.In this episode of Talking techniques, supported by Oxford Nanopore, Senior Investigator Michael Dean and Post-baccalaureate Fellow Nicole Rossi, from the NIH's National Cancer Institute (MD, USA), discuss their research into the relationship between HPV and cervical cancer. Expounding on the points mentioned above, they reveal the tremendous insights into cancer and immunology still to be gained, document the key tools used in their studies and explain how their work can be translated into more effective immunotherapies and treatments for cervical cancer.

In part one we discussed the impacts the technology has had on both improving the clinical diagnosis and management of rare diseases and on drug development and basic research studies.This episode goes beyond the technology's capabilities and into the debates surrounding how, when and why they should be used. What needs to change for the technique to be applied equitably? And how does reality stack up against science fiction in terms of people's perceptions of ubiquitous WGS?To do this I speak with David Dimmock, Senior Medical Director of the Rady Children's Institute for Genomic Medicine (CA, USA); Christine Stanley, Chief Director of Clinical Genomics, Variantyx (MA, USA); and Take Ogawa, Vice President of Sales & Marketing at Psomagen (MD, USA). Each of these speakers provides their opinions on the impacts of race, religion and way of life on the application of WGS and how much is too much data.Contents:Introductions: 00:00-02:20Gauging public perceptions of routine WGS 02:20-05:40The role of industry in improving WGS accessibility and capabilities: 05:40-07:35The appropriate use of pre-symptomatic and predictive risk findings: 08:00-11:15Debating the discovery of untreatable diseases: 11:15-12:45The impact of data biases in gene sequencing and the lack of gene references for different populations: 12:45-14:45The impact of religion and lifestyle on ethical considerations in the use of WGS data: 14:45-16:00Dealing with unintended findings or results that impact relatives: 16:00-16:45The value of WGS in pharmacogenomic variant findings and challenging the ACMG59 list: 16:45-19:20Striking the balance between fully utilizing WGS for all potential findings and ensuring maximum participation for all groups: 19:20-22:45Filtering data to avoid exclusion: 22:45-24:10Who owns WGS data? 24:10-25:15Consent conversations: 25:15-26:30Final comments: 26:30-27:15 See acast.com/privacy for privacy and opt-out information.

Providing me with an insight into the world of PCR diagnostics is Tyler Miller, Clinical Pathology Resident and Research Fellow at Massachusetts General Hospital (MA, USA), where he was instrumental in setting up the testing regimen for the Hospital.Ty details the attributes of PCR that lead to it becoming the gold standard for diagnostic tests, before explaining the variance in clinical detection rate during a patient's disease course and how this variation correlates with the infectivity of the patient. Ty also delves into the variety of sample collection methods available, how each of these methods compares in terms of sensitivity and their ability to be integrated into exciting novel PCR techniques.We also look at the work of the Broad Institute in establishing a mass testing effort that involved automation, workflow optimization and hundreds of new staff, ultimately leading to the delivery of 100,000 tests a day, almost 5% of the USA's total COVID-19 testing at the time. All of this rapid work has led to dramatic changes in the PCR technique and process. These changes are perhaps exemplified by PCR testing without RNA extraction and purification, which Ty explains was partly developed due to the limited supplies available to researchers at the beginning of the pandemic.ContentsIntroduction: 00:00-02:00Why PCR tests are so valuable: 02:00-03:10Changes in clinical detection rate and infectivity: 03:10-8:00Infectivity and exceptions to the rule: 08:00-09:00Sample collection methods, sensitivity and encouraging testing uptake 09:00-17:00The Broad Institute's mass testing regimen: 17:00-21:00Developments during the pandemic and no RNA extraction PCR: 21:00-27:00Dreams for improving COVID-19 testing: 27:00- 30:00This episode was supported by Roche sequencing and life science.

To do this I speak to two researchers driving forward reproducibility in the life sciences, Marc Raphael from the United States Naval Research Laboratory, and Elizabeth Iorns, CEO of Science Exchange. Marc discusses his recent trial of independent verification and validation (IV&V) labs in a live science setting, highlighting the lessons learned from the experience and exploring the differences observed in attitudes and approaches to reproducibility between the life sciences and engineering, where mark began his career. Elizabeth discusses her work with Science Exchange and the reproducibility project: cancer biology. Elizabeth notes the key themes that have been exposed by the reproducibility project that are holding back the resolution of the crisis and explains what she thinks has worked so far in improving reproducibility. This leads to a fascinating discussion between Marc and Elizabeth, comparing and contrasting their experiences and noting the different challenges that they face in trying to improve the state of research in the life sciences.
