The Peer Review Process: Past, Present, and Future.

The peer review process is a fundamental aspect of modern scientific paper publishing, underpinning essential quality control. First conceptualised in the 1700s, it is an iterative process that aims to elevate scientific literature to the highest standards whilst preventing publication of scientifically unsound, potentially misleading, and even plagiarised information. It is widely accepted that the peer review of scientific papers is an irreplaceable and fundamental aspect of the research process. However, the rapid growth of research and technology has led to a huge increase in the number of publications. This has led to increased pressure on the peer review system. There are several established peer review methodologies, ranging from single and double blind to open and transparent review, but their implementation across journals and research fields varies greatly. Some journals are testing entirely novel approaches (such as collaborative reviews), whilst others are piloting changes to established methods. Given the unprecedented growth in publication numbers, and the ensuing burden on journals, editors, and reviewers, it is imperative to improve the quality and efficiency of the peer review process. Herein we evaluate the peer review process, from its historical origins to current practice and future directions.

Transitions in development - an interview with Sonia Sen.

Sonia Sen is Group Leader at the Tata Institute for Genetics and Society in Bangalore, India. Her group is interested in understanding neurodevelopment and behaviour in Drosophila and Anopheles. We spoke to Sonia over a video call to talk about her research career, her transition to becoming a group leader, and the work that the Indian Society of Developmental Biologists is doing.

History of biological, mechanistic, and clinical understanding of concussion.

The history behind the biological, mechanistic, and clinical insights into concussion provides awareness of the current understanding and future areas for study. Although the initial description of concussion appeared in the 10th century, the potential long-term structural consequences were first defined by Harrison Martland, M.D., who performed a postmortem study of former boxers in 1928. He found evidence of perivascular microhemorrhage that he believed eventually evolved into a "replacement gliosis" underlying a clinical syndrome that he named "punch drunk," which was characterized by acute confusion with chronic cognitive and physical symptoms developing in those with prolonged exposure. Further research into the potential long-term consequences of repetitive concussions, particularly in athletics and the military, led to an understanding of chronic traumatic encephalopathy. To ameliorate possible long-term risks, research has been focused on preventative and therapeutic measures for concussion. In this review article, the authors present the history of concussion and the long-term sequelae of repeated head injury. Specifically, they consider how the understanding of concussion has evolved from antiquity into the modern era, and how this change in understanding of head injury has led to an appreciation of the fact that its long-term implications sometimes manifest as the clinical and histopathological entity of chronic traumatic encephalopathy.

The history and potential future of monoclonal antibody therapeutics development and manufacturing in four eras.

Therapeutic monoclonal antibody (mAb) development and the processes for manufacturing drug substance have evolved since the first approval of the mAb in 1986. As the past is often the prologue to the future, the history of these technologies has been classified here into three eras, leading to speculation about what the next era may hold with regard to development and manufacturing strategies, as well as the potential impacts to patients. The substantial increase in production culture titers and bioreactor production volumes and the availability of large-scale contract manufacturing facilities could translate into improved global access for these therapies and an expansion of indications for therapeutic antibodies.

Interview with Andrea Graham, who studies the ecological and evolutionary causes of immunological heterogeneity in mammals at Princeton University.

The people behind the papers - Alyshia Scholl, Yihong Liu and Geraldine Seydoux.

Germ granules have been hypothesized to deliver mRNAs of germ cell fate determinants to primordial germ cells. Now, a new study in Development finds that many mRNAs enriched in germ granules are not involved in germline development in Caenorhabditis elegans. To find out more about the story behind the paper, we caught up with first author Alyshia Scholl, second author Yihong Liu and corresponding author Geraldine Seydoux, Professor at Johns Hopkins University School of Medicine.

HISTOMONAS MELEAGRIDIS INFECTIONS IN TURKEYS IN THE USA: A CENTURY OF PROGRESS, RESURGENCE, AND TRIBUTE TO ITS EARLY INVESTIGATORS, THEOBALD SMITH, ERNST TYZZER, AND EVERETT LUND.

Histomoniasis, caused by the protozoan, Histomonas meleagridis, is an economically important disease of turkeys, and it also affects several other species of domesticated and wild Galliformes, including chickens. Under natural conditions, the parasite is transmitted through eggs of a nematode, Heterakis gallinarum, that shares its hosts with Hi. meleagridis. The protozoan infects tissues of both male and female He. gallinarum and eventually is carried within the worm egg. Histomonas meleagridis more readily infects and develops in chickens, and the proximity of chicken farms is a major risk factor for outbreaks in turkeys. Chemoprophylaxis had controlled Hi. meleagridis in turkeys very successfully, but histomoniasis has recently reemerged in turkeys because anti-histomonal drugs are no longer permitted by the United States Food and Drug Administration because of the concerns for residual toxins in poultry meat. Horizontal transmission of the protozoan in the absence of worm eggs remains a mystery because the flagellate trophozoite excreted in the feces of turkeys is not viable for any length of time. A proposed resistant stage of the protozoan has not yet been conclusively demonstrated. Here we review the discovery of the protozoan and the current status of the disease and its control.

The History of Agrobacterium Rhizogenes: From Pathogen to a Multitasking Platform for Biotechnology.

Agrobacterium's journey has been a roller coaster, from being a pathogen to becoming a powerful biotechnological tool. While A. tumefaciens has provided the scientific community with a versatile tool for plant transformation, Agrobacterium rhizogenes has given researchers a Swiss army knife for developing many applications. These applications range from a methodology to regenerate plants, often recalcitrant, to establish bioremediation protocols to a valuable system to produce secondary metabolites. This chapter reviews its discovery, biology, controversies over its nomenclature, and some of the multiple applications developed using A. rhizogenes as a platform.
