Mitochondrial replacement techniques have the potential to allow prospective parents who are at risk of passing on debilitating or even life-threatening mitochondrial disorders to have healthy children to whom they are genetically related. Ethical concerns have however been raised about these techniques. This article focuses on one aspect of the ethical debate, the question of whether there is any moral difference between the two types of MRT proposed: Pronuclear Transfer and Maternal Spindle Transfer. It examines how questions of identity impact (...) on the ethical evaluation of each technique and argues that there is an important difference between the two. PNT, it is argued, is a form of therapy based on embryo modification while MST is, instead, an instance of selective reproduction. The article's main ethical conclusion is that, in some circumstances, there is a stronger obligation to use PNT than MST. (shrink)

Mitochondrial DNA (mtDNA) diseases are a group of neuromuscular diseases that often cause suffering and premature death. New mitochondrial replacement techniques (MRTs) may offer women with mtDNA diseases the opportunity to have healthy offspring to whom they are genetically related. MRTs will likely be ready to license for clinical use in the near future and a discussion of the ethics of the clinical introduction ofMRTs is needed. This paper begins by evaluating three concerns about the safety of MRTs for clinical (...) use on humans: (1) Is it ethical to use MRTs if safe alternatives exist? (2) Would persons with three genetic contributors be at risk of suffering? and (3) Can society trust that MRTs will be made available for humans only once adequate safety testing has taken place, and that MRTs will only be licensed for clinical use in a way that minimises risks? It is then argued that the ethics debate about MRTs should be reoriented towards recommendingways to reduce the possible risks of MRT use on humans. Two recommendations are made: (1) licensed clinical access to MRTs should only be granted to prospective parents if they intend to tell their children about their MRT conception by adulthood; and (2) sex selection should be used in conjunction with the clinical use ofMRTs, in order to reduce transgenerational health risks.

Currently in the United Kingdom, anyone donating gametes has the status of an open-identity donor. This means that, at the age of 18, persons conceived with gametes donated since April 1, 2005 have a right to access certain pieces of identifying information about their donor. However, in early 2015, the UK Parliament approved new regulations that make mitochondrial donors anonymous. Both mitochondrial donation and gamete donation are similar in the basic sense that they involve the contribution of gamete materials to (...) create future persons. Given this similarity, this paper presumes that both types of donor should be treated the same and made open-identity under the law, unless there is a convincing argument for treating them differently. I argue that none of the existing arguments that have been made so far in favor of mitochondrial donor anonymity are convincing and mitochondrial donors should therefore be treated as open-identity donors under UK law.

Although best known as a scientific instrument maker, John Rowley extended his sphere of activity very considerably as Master of Mechanics to George I and as a hydraulic engineer at the Offices of Ordnance and Works. Re-examined and untapped sources provide fresh evidence of these aspects of his work and highlight his predilection for the arts and the virtuosity of his artefacts. The findings also have implications for studies of the instrument-making trade in the early eighteenth century.

Well-known in his day, but overlooked since, Erasmus King lectured in natural and experimental philosophy from the 1730s until 1756 at his Westminster home and twenty other venues, publicizing his frequent courses exclusively in the Daily Advertiser. In 1739 he escorted Desaguliers's youngest son to Russia, hoping to demonstrate experimental philosophy to the Russian empress. En route, he conducted trials with a sea-guage in the Baltic which were reported by Stephen Hales in his Statical Essays. Various sources testify to King's (...) subsequent experimental research for Hales in the fields of anatomy, respiration and electricity. There is recorded evidence for the exceptional range and quality of King's scientific apparatus and models. (shrink)

The COVID-19 pandemic has exacerbated inequalities, including among the healthcare workforce. Based on recent literature and drawing on our experiences of working in operating theatres and critical care in the UK’s National Health Service during the pandemic, we review the role of personal protective equipment and consider the ethical implications of its design, availability and provision at a time of unprecedented demand. Several important inequalities have emerged, driven by factors such as individuals purchasing their own personal protective equipment, inconsistencies between (...) guidelines issued by different agencies and organisations, and the standardised design and procurement of equipment required to protect a diverse healthcare workforce. These, we suggest, have resulted largely because of a lack of appropriate pandemic planning and coordination, as well as insufficient appreciation of the significance of equipment design for the healthcare setting. As with many aspects of the pandemic, personal protective equipment has created and revealed inequalities driven by economics, gender, ethnicity and professional influence, creating a division between the ‘haves’ and ‘have-nots’ of personal protective equipment. As the healthcare workforce continues to cope with ongoing waves of COVID-19, and with the prospect of more pandemics in the future, it is vital that these inequalities are urgently addressed, both through academic analysis and practical action. All data relevant to the study are included in the article. (shrink)
