As various advisory bodies, scientific organizations and funding agencies deliberate on genome editing in humans, Debra J. H.

Selection against embryos that are predisposed to develop disabilities is one of the less controversial uses of embryo selection technologies ( EST s). Many bio‐conservatives argue that while the use of EST s to select for non‐disease‐related traits, such as height and eye‐colour, should be banned, their use to avoid disease and disability should b...

Reproductive genetic technologies (RGTs) allow parents to decide whether their future children will have or lack certain genetic predispositions. A popular model that has been proposed for regulating access to RGTs is the 'genetic supermarket'. In the genetic supermarket, parents are free to make decisions about which genes to select for their chil...

Polygenic genome editing in human embryos and germ cells is predicted to become feasible in the next three decades. Several recent books and academic papers have outlined the ethical concerns raised by germline genome editing and the opportunities that it may present1, 2–3. To date, no attempts have been made to predict the consequences of altering...

Disagreements about language use are common both between and within fields. Where interests require multidisciplinary collaboration or the field of research has the potential to impact society at large, it becomes critical to minimize these disagreements where possible. The development of diverse intelligent systems, regardless of the substrate (e....

Background Implementing genomic sequencing into newborn screening programs allows for significant expansion in the number and scope of conditions detected. We sought to explore public preferences and perspectives on which conditions to include in genomic newborn screening (gNBS). Methods We recruited English-speaking members of the Australian publ...

Introduction Newborn bloodspot screening (NBS) is a highly successful public health programme that uses biochemical and other assays to screen for severe but treatable childhood-onset conditions. Introducing genomic sequencing into NBS programmes increases the range of detectable conditions but raises practical and ethical issues. Evidence from pro...

Stem cell-derived embryo models (SCEMs) are model embryos used in scientific research to gain a better understanding of early embryonic development. The way humans develop from a single-cell zygote to a complex multicellular organism remains poorly understood. However, research looking at embryo development is difficult because of restrictions on t...

Background Implementing genomic sequencing into newborn screening programs allows for significant expansion in the number and scope of conditions detected. We sought to explore public preferences and perspectives on which conditions to include in genomic newborn screening (gNBS). Methods We recruited English-speaking members of the Australian publ...

Human brain organoids are three-dimensional masses of tissues derived from human stem cells that partially recapitulate the characteristics of the human brain. They have promising applications in many fields, from basic research to applied medicine. However, ethical concerns have been raised regarding the use of human brain organoids. These concern...

Recent dramatic reductions in the timeframe in which genomic sequencing can deliver results means its application in time-sensitive screening programs such as newborn screening (NBS) is becoming a reality. As genomic NBS (gNBS) programs are developed around the world, there is an increasing need to address the ethical and social issues that such in...

The use of novel technologies in the selection of embryos during in vitro fertilisation (IVF) has the potential to improve the chances of pregnancy and birth of a healthy child. However, it is important to be aware of the potential risks and unintended consequences that may arise from the premature implementation of these technologies. This article...

This paper examines the ethics of introducing emerging forms of artificial intelligence (AI) into prenatal and pediatric genomic medicine. Application of genomic AI to these early life settings has not received much attention in the ethics literature. We focus on three contexts: (1) prenatal genomic sequencing for possible fetal abnormalities, (2)...

In this paper, we outline how one might conduct a comprehensive ethical evaluation of human brain organoid transplantation in animals. Thus far, ethical concerns regarding this type of research have been assumed to be similar to those associated with other transplants of human cells in animals, and have therefore not received significant attention....

Recently, Australia became the second jurisdiction worldwide to legalize the use of mitochondrial donation technology. The Mitochondrial Donation Law Reform (Maeve's Law) Bill 2021 allows individuals with a family history of mitochondrial disease to access assisted reproductive techniques that prevent the inheritance of mitochondrial disease. Using...

Integrating neural cultures developed through synthetic biology methods with digital computing has enabled the early development of Synthetic Biological Intelligence (SBI). Recently, key studies have emphasized the advantages of biological neural systems in some information processing tasks. However, neither the technology behind this early develop...

In this article, we provide an ethical analysis of the first porcine cardiac xenotransplant, performed in Maryland, USA in early 2022. David Bennett was offered the experimental procedure after he was deemed ineligible for human heart transplantation and mechanical circulatory support, based on a history of non-compliance. It was reported that Mr B...

Genomic sequencing (GS) is increasingly used in paediatric medicine to aid in screening, research and treatment. Some health systems are trialling GS as a first-line test in newborn screening programmes. Questions about what to do with genomic data after it has been generated are becoming more pertinent. While other research has outlined the ethica...

Rapid genomic testing (rGT) enables genomic information to be available in a matter of hours, allowing it to be used in time-critical settings, such as intensive care units. Although rGT has been shown to improve diagnostic rates in a cost-effective manner, it raises ethical questions around a range of different areas, including obtaining consent a...

Genomic sequencing generates huge volumes of data, which may be collected or donated to form large genomic databases. Such information can be stored for future use, either for the data donor themselves or by researchers to help improve our understanding of the genetic basis of disease. Creating datasets of this magnitude and diversity is only possi...

Ultra-rapid genomic sequencing (urGS) is increasingly used in neonatal and pediatric intensive care settings (NICU/PICU), demonstrating high diagnostic and clinical utility. This study aimed to explore the perspectives of healthcare professionals (HPs) and the challenges raised by urGS, particularly when making treatment decisions. Four focus group...

Representations of brain organoids in the media are often negatively or positively exaggerated without appropriate discussion. Here, we examine two topics (the possibility of consciousness and medical applications) and call on scientists, ethicists, and the media to represent brain organoid research and its ethical issues more accurately.

Diagnostic genomic sequencing generates unprecedented amounts of data. In addition to its primary use, this data could be used for a wide range of secondary purposes, including research and informing future healthcare for the data donor. These opportunities may require data to be shared with third parties. Although effective data sharing relies on...

The clinical utility of rapid genome sequencing (rGS) in critically unwell infants has been consistently demonstrated, and there are calls for rGS to be implemented as a first-line test in the NICU. A diagnosis from rGS can enable rapid initiation of precision treatment, making it potentially lifesaving. However, in many patients rGS leads to the d...

Numerous chronic diseases have a substantial hereditary component. Recent advances in human genetics have allowed the extent of this to be quantified via genome-wide association studies, producing polygenic risk scores (PRS), which can then be applied to individuals to estimate their risk of developing a disease in question. This technology has rec...

DNA databases have significant commercial value. Direct-to-consumer genetic testing companies have built databanks using samples and information voluntarily provided by customers. As the price of genetic analysis falls, there is growing interest in building such databases by paying individuals for their DNA and personal data. This paper maps the et...

Rapid genomic sequencing (rGS) is being increasingly used in neonatal and paediatric intensive care units. While there is emerging evidence of clinical utility and cost-effectiveness, concerns have been raised regarding the impact of delivering genomic results in an acute care setting. To help investigate these concerns, we analysed survey data col...

Genomic sequencing technologies (GS) pose novel challenges not seen in older genetic technologies, making traditional standards for fully informed consent difficult or impossible to meet. This is due to factors including the complexity of the test and the broad range of results it may identify. Meaningful informed consent is even more challenging t...

Although rapid genomic sequencing (RGS) is improving care for critically ill children with rare disease, it also raises important ethical questions that need to be explored as its use becomes more widespread. Two such questions relate to the degree of consent that should be required for RGS to proceed and whether it might ever be appropriate to ove...

The scope of noninvasive prenatal testing (NIPT) could expand in the future to include detailed analysis of the fetal genome. This will allow for the testing for virtually any trait with a genetic contribution, including “non-medical” traits. Here we discuss the potential use of NIPT for these traits. We outline a scenario which highlights possible...

Lockdowns and quarantines have been implemented widely in response to the COVID-19 pandemic. This has been accompanied by a rise in interest in the ethics of ‘passport’ systems that allow low-risk individuals greater freedoms during lockdowns and exemptions to quarantines. Immunity and vaccination passports have been suggested to facilitate the gre...

In this paper, we investigate how data about public preferences may be used to inform policy around the use of controversial novel technologies, using public preferences about autonomous vehicles (AVs) as a case study. We first summarize the recent ‘Moral Machine’ study, which generated preference data from millions of people regarding how they thi...

Genetic variants that influence susceptibility to COVID-19 have recently been identified. In this manuscript, we identify and discuss some of the ethical and practical issues raised by these studies. We first outline the ethical case for providing COVID-19 susceptibility testing to healthcare workers, as well as highlighting risks associated with p...

Many controversies in bioethics turn on questions of moral status. Some moral status issues have received extensive bioethical attention, including those raised by abortion, embryo experimentation, and animal research. Beyond these established debates lie a less familiar set of moral status issues, many of which are tied to recent scientific breakt...

Despite substantial advances in our understanding of many somatic diseases, the nature of many psychiatric disorders remains elusive. This chapter shows how an appreciation of the multilevel causal nature of psychiatric disorders can move these debates forward. It first examines the ways in which genetic risk factors interact with environmental fac...

Psychiatry Reborn: Biopsychosocial Psychiatry in Modern Medicine is a comprehensive collection of essays by leading experts in the field, and provides a timely reassessment of the biopsychosocial approach in psychiatry. Spanning the sciences and philosophy of psychiatry, the essays offer complementary perspectives on the ever more urgent importance...

CRISPR-Cas9 has revolutionised genome engineering and has the potential to radically change our approach to genetic disease. However, the potential for genetic modification of embryos has raised significant and complex ethical and social concerns. The scientific community have called for ongoing stakeholder consultation about Germline Gene Editing...

Here, a moral case is presented as to why sign languages such as Auslan should be made compulsory in general school curricula. Firstly, there are significant benefits that accrue to individuals from learning sign language. Secondly, sign language education is a matter of justice; the normalisation of sign language education and use would particular...

Spinal muscular atrophy (SMA) is the most common genetic disease that causes infant mortality. Its treatment and prevention represent the paradigmatic example of the ethical dilemmas of 21st‐century medicine. New therapies (nusinersen and AVXS‐101) hold the promise of being able to treat, but not cure, the condition. Alternatively, genomic analysis...

In vitro gametogenesis (IVG) might offer numerous research and clinical benefits. Some potential clinical applications of IVG, such as allowing opposite‐sex couples experiencing infertility to have genetically related children, have attracted support. Others, such as enabling same‐sex reproduction and solo reproduction, have attracted significantly...

Non‐invasive prenatal testing (NIPT) can determine the sex of the fetus very accurately and very early in gestation. There are concerns that the ease, timing and accuracy of NIPT sex determination will facilitate sex‐selective termination of pregnancy (TOP). Here we review current practice, the evidence for a link between NIPT and sex‐selective TOP...

Studies have provided rich data on global preferences for how autonomous vehicles should act in collisions. We describe a framework for incorporating such preferences in policy. Preferences should inform the design of autonomous vehicles only after being screened for bias and only to the degree to which they match major ethical theories.

Preimplantation genetic diagnosis (PGD) allows the detection of genetic abnormalities in embryos produced through in vitro fertilization (IVF). Current funding models in Australia provide governmental subsidies for couples undergoing IVF, but do not extend to PGD. There are strong reasons for publicly funding PGD that follow from the moral principl...

The precautionary principle aims to influence decision‐making in contexts where some activity poses uncertain but potentially grave threats. This perfectly describes the controversy surrounding germline gene editing. This article considers whether the precautionary principle should influence how we weigh the risks and benefits of human germline int...

It is likely that gene editing technologies will become viable in the current century. As scientists uncover the genetic contribution to personality traits and cognitive styles, parents will face hard choices. Some of these choices will involve trade‐offs from the standpoint of the individual's welfare, while others will involve trade‐offs between...

Background: Non-invasive prenatal testing (NIPT) has been available in Australia on a user-pays basis since 2012. Since its introduction, it has grown in popularity as a screening method for fetal aneuploidy and may become publicly funded. Aims: To assess the motivations and experiences of women who have undergone NIPT in a user-pays system in A...

Non-invasive prenatal testing (NIPT) is at the forefront of prenatal screening. Current uses for NIPT include fetal sex determination and screening for chromosomal disorders such as trisomy 21 (Down syndrome). However, NIPT may be expanded to many different future applications. There are a potential host of ethical concerns around the expanding use...

In July 2018, the Nuffield Council of Bioethics released its long-awaited report on heritable genome editing (HGE). The Nuffield report was notable for finding that HGE could be morally permissible, even in cases of human enhancement. In this paper, we summarise the findings of the Nuffield Council report, critically examine the guiding principles...

NICUs are a priority implementation area for genomic medicine. Rapid genomic testing in the NICU is expected to be genomic medicine's "critical application," providing such clear benefits that it drives the adoption of genomics more broadly. Studies from multiple centers worldwide have now demonstrated the clinical utility and cost-effectiveness of...

The CRISPR-cas9 genome editing system (CRISPR) has been used to make precise and heritable changes to a diverse range of animals. The use of CRISPR to edit embryonic cells initially raised widespread criticism and calls for an international ban. However, the rapid development of genome editing has prompted governments around the world to review the...

Advances in genome editing techniques have generated renewed interest in the ethical implications of genetic modification. In this article, we review the recent literature and discuss in detail ethical issues pertaining to the application of this technology to five areas; human embryo research, organoid research, the prospect of genetically modifie...

Advances in biotechnology mean that it may soon be possible to recreate previously extinct species. This has led to an emerging debate within bioethics about whether we ought to reintroduce extinct species into our ecosystems. In this paper, we discuss the role that biodiversity could play in this debate. Many believe that biodiversity is a good th...

Dolly, the sheep, was the first mammal cloned from a somatic cell using a technique called somatic cell nuclear transfer. The announcement of her birth in 1997 sparked a heated debate about the ethics of human reproductive cloning, resulting in most countries legally banning it. Some of the reasons why someone may want to create a human clone are b...

Germline Gene Editing (GGE) has enormous potential both as a research tool and a therapeutic intervention. While other types of gene editing are relatively uncontroversial, GGE has been strongly resisted. In this article, we analyse the ethical arguments for and against pursuing GGE by allowing and funding its development. We argue there is a stron...

One argument that is sometimes made against pursuing radical forms of human life extension is that such interventions will make the species less evolvable, which would be morally undesirable. In this article, I discuss the empirical and evaluative claims of this argument. I argue that radical increases in life expectancy could, in principle, reduce...

The publication of the first study to use gene editing techniques in human embryos (Liang et al., 2015) has drawn outrage from many in the scientific community. The prestigious scientific journals Nature and Science have published commentaries which call for this research to be strongly discouraged or halted all together (Lanphier et al., 2015; Bal...

One debate in contemporary bioethics centers on whether the development of cognitive enhancement technologies (CETs) will hasten the need for moral enhancement. In this article we provide a new argument in favor of pursuing these enhancement technologies together. The widespread availability of CETs will likely increase population-level cognitive d...

In this thesis I develop a novel perspective on human enhancement and its moral and philosophical implications. I begin by describing the scientific developments that have ignited a debate within bioethics on human enhancement and reviewing the ways in which the concept of enhancement has been analysed in the philosophical literature. I then descri...

Many of the existing ethical analyses of genetic engineering technologies (GET) focus on how they can be used to enhance individuals—to improve individual well-being, health and cognition. There is a gap in the current literature about the specific ways enhancement technologies could be used to improve our populations and species, viewed as a whole...
