Why would someone elect to have their eggs frozen? The main reason is to store these delicate cells so that they can be used in the future. The technique of freezing and storing sperm cells and embryos has been undertaken for many years. However, the use of frozen eggs for infertility treatment is a relatively new technique. Eggs do not freeze as well as embryos, and in fact, fertilisation of a frozen egg is less likely to result in pregnancy. In this podcast, I will explore the processes involved in freezing eggs, namely the use of cryoprotectant and vitrification, and will discuss both the advantages and disadvantages of undergoing such treatment.

The situational factors that influence any type of social interaction (e.g. the physical environment, the presence of other people) can be applied to sport in very specific ways. This podcast will consider some of the theories and studies that can be applied when considering the topic of sport within social contexts.

It is crucial that animals with a cardiovascular system can slow (and ultimately prevent) blood loss from injury or damage to body tissues. In addition, the skin (and accompanying secretions from sebaceous glands) is a highly effective barrier to pathogens such as bacteria, viruses and fungi. The repair of skin is vital to the prevention of contraction of infectious diseases. The faster the organism can ‘plug the leak’, the less blood loss will occur and the chance of infection will be reduced. In this podcast, I will explain how the blood clotting cascade is initiated, and describe the interactions between the different molecules involved in the process. I'll look in detail at some of the genetic conditions linked to problems with the blood clotting cascade mechanism and will explore how some venomous animals use blood clotting biochemistry to their advantage.

As we begin to unlock the secrets held in our DNA, we could all live healthier, for a lot longer - but how much longer is the key question…how far can we push the boundaries? How do we defy the natural phenomenon of ageing...but more importantly, what implications would it have? In this podcast, I’d like to explore the current scientific and medical restrictions on life and how with advances in science, we may be able to overcome them. This in itself raises a number of serious concerns; what might the social, economic, and ethical implications be of everyone living the lives truly to the fullest – with an ever increasing population, how does that affect access to resources, which as we know, are limited?

Rewilding offers a possible solution to reverse our rapidly deteriorating rural landscape. The natural world is often seen as a resource merely to exploit and the hunting of wild animals in the UK was only banned in 2004. The reintroduction of key species would have positive ecological consequences; a reduction in the number of invasive species, a reduction in the level of soil erosion and the straightening of river channels thereby creating more diverse wildlife habitats, to name but a few. In this podcast, I will discuss the ability of rewilding to potentially rebalance the UK’s landscape. (With thanks to Grace B for conducting the research and providing the content for this podcast)

Around 273 million sharks are killed each year globally. They’re feared as the archetypal killing machine, and there’s profit to be made from shark-derived products; but they may be more economically and environmentally valuable alive than dead. This podcast will evaluate the psychological, economical, gastronomical, medical, ethical and ecological arguments for killing these creatures as opposed to protecting them, and in doing so, will aim to answer the question of whether: should we continue to kill sharks?

Worldwide, the number of potential pathogens is very large, while the resources for disease research and development is limited. To ensure efforts under the World Health Organisation’s blueprint are focused and productive, a list of diseases and pathogens are prioritized for research in public health emergency contexts – what is fascinating, is that nearly all pathogens on the list are viruses. In this podcast, I will explore how particular viruses have shaped healthcare on a global scale. (With thanks to Hephzibah P for conducting the research and providing the content for this podcast)

We are all born with the neural architecture and ability to develop empathy and compassion, but to remain a good person, we must have a series of positive experiences throughout our lives. The Pygmalion effect may certainly account for why people choose to do bad things, but perhaps we should consider other psychological forces; cognitive dissonance, conformity, and obedience to authority. In this podcast, I will explore why good people do bad things - from a phycological perspective. (With thanks to Jess B for conducting the research and providing the content for this podcast)

The perceived role of God in illness and recovery is a primary influence upon the health care beliefs and behaviours of people. Only by understanding an individual's religious beliefs can medical practitioners effectively meet their health care needs, a concept which I examine in this extended podcast.
