This episode details the key ingredients in fertilisers: nitrogen, phosphorus, and potassium. It outlines the chemical production of nitrogen-based fertilisers, specifically ammonium nitrate, highlighting its rich nitrogen content due to its dual sources. We explain that phosphat ...  Show more

In this episode, we look at plants and nitrogen.Plants require nitrogen to produce proteins necessary for growth. While the atmosphere is full of nitrogen gas, plants cannot directly utilise this form. Instead, they absorb soluble nitrates from the soil. Crop harvesting depletes ...  Show more

This episode explores the historical shift in drug discovery from natural sources to synthetic production. 

Initially, many essential medicines like Digitalis and Aspirin were derived directly from plants, highlighting the importance of botanical resources</stron ...

In this episode, Jamie explores the fascinating world of prokaryotic cells, focusing on their unique features such as plasmids, the absence of mitochondria and chloroplasts, and their distinctive way of storing genetic material.

This discussion is particularly valuable ...

In this episode, we’ll explore the distinct characteristics of prokaryotic cells and what sets them apart from more complex cell types. We’ll discuss the presence of plasmids—small DNA rings that enable genetic information exchange. We’ll examine how prokaryotic cells lack mem ...

In this episode, we look at evidence supporting the theory of evolution. Fossil records demonstrate the incremental changes in organisms throughout extended timeframes. Furthermore, the development of antibiotic-resistant bacteria is highlighted as an example of natural selection ...  Show more
