  • Analysis of the clinical trials evolution
  • New advancements in the field of biotechnology transformed clinical trial processes in 2020/21. These processes used to be very labour intensive and required trial participants to be in-person present in the clinic to record their symptoms and receive treatment. Currently, clinical trials are heavily digitalised, which allows quick testing of a substantial number of patients (An example is an Invitae app working through Apple Watch).

  • Analysis of personalised treatment in the mitigation of rare diseases
  • It is possible to make treatment more personalised by reducing genetic sequencing costs. With the implementation of more extensive screening of patients, it is expected to make interventions more personalised with targeted therapies and more effective treatment plans.

  • Increase of agricultural yields with the introduction of biotechnology innovations
  • Global trends suggested that biotechnology provided a considerable number of opportunities for improving agricultural yields. For example, corn and wheat can be altered to withstand harsh environmental conditions, while producing high yields. The issue is highly important in the environment of the growing world population that puts pressure on biological resources, land, and supply chains.

  • The development of value-based pricing models
  • Value-based pricing agreements presume that a seller and a buyer link the respective payments to a specified value that is achieved as opposed to the volume of sales. The indicated agreements are aimed at aligning the incentives between the purchasers and manufacturers of various products. Value-based pricing models in healthcare for instance may presume a lower-payment for drugs unless they prove their high efficiency compared to other treatment methods.

  • The development of pig-to-human transplantation systems
  • The idea of transplanting animal organs to humans raises ethical issues, however, despite unclear consequences, the trend is gaining considerable momentum. Several approaches are tested for successful transplantation of various organs. For instance, by using CRISPR organs it is possible to transplant pig hears to baboons.

  • Assessment of new trends in cell and gene medicine
  • Currently, more than 800 therapies are approved for clinical applications. The respective treatments include CAR T-cell treatments for applications against cancer and bona fide gene therapy.

  • Investigation of gain-of-function mutations migrating from specie to specie
  • It was shown that species that originate from the same appendage may manifest gain-of-function mutations under certain conditions. For instance, a gain-of-function mutation was identified in the zebrafish that resulted in the formation of several additional bone sets in the fin.

  • The use of big data in the investigation of plant development
  • Big data presents a collection of information that covers a substantial number of species, their habitat, behaviour and nutrition. With 2020/21 developments in computational technologies it became possible to predict the distribution of different plant species in different habitats with greater precision.

  • Analysis of the accumulation of genetic differences by twins in the womb
  • Cell division is an important aspect of cellular microbiology and possible replication errors were shown to the development of a considerable number of diseases. DNA replication errors can be studied on monozygotic twins, providing information on possible developments leading to cancer.

  • Investigations of gene activity regulators in animals
  • Short DNA regions with direct gene expression have been evolving over the last 700 years. The trend has emerged over 2020/21 as a possible approach to generating organisms with necessary properties.

  • Investigation of simultaneous transcriptomic and epigenomic profiling from the same cell
