What exactly do we mean by cancer? Essentially, cancer is the uncontrolled proliferation of cells which lead to the formation of a tumour. The distinct differences between benign and malignant tumours are explained in this podcast, along with current treatments for both. Mr I also reveals how gene mutations can lead to cancer.

In this podcast, Mr I discusses two recently published articles about HIV therapy. CD4 T lymphocytes are known to act as viral reservoirs in those on antiretroviral therapy, but could the use of metabolic activity inhibitors help to destroy them? Equally, could the inflammatory marker GlycA indicate a greater risk of atherosclerosis in HIV patients?

As I look into the eyes of my rescue greyhound Luca, I wonder if the connection goes deeper than him simply wanting to be fed. They say that dogs are man's best friend, but why is that? Is there a biological reason why dogs are so loving and trusting? 

What are stem cells, and how can we harvest them to treat disease? Moreover, which type of stem cell should we use?

What happens to a body after death, and how can an autopsy reveal the exact cause, manner and time of death?

In this podcast, Mr I describes the group of symptoms that characterises dementia, with focus on Alzheimer's disease.

Emma T (Year 13 Biology student) discusses the mechanisms that might allow humans to use photosynthesis.

Just how unreliable are facial composites based on eyewitness testimony, and how might biometrics help?

With stories of 'miracle cures' for diseases like cancer being shared thousands of times on social media, Mr I considers the consequences of fake medical news.

Why do we have innate behaviours, and what distinguishes them from learnt responses?
