This episode features Dr Marcin Barszczewski, Dr Aleks Marsh and Dr Alan Mullan discussing how modern-day DNA can determine your ancestral heritage? What is the difference between being related to and being descended from someone? What are the different types of DNA tests, what are they used for and what information can we get from them?

In this episode Aleks, Alan and Conor discuss what is organic farming? We consider whether organic farming methods which aim to reduce the use of synthetic pesticides, herbicides and the use of antibiotics provide a more sustainable method of food production. We discuss is organic food standardized by a central body? Is organic farming separate from fair trade standards and animal welfare practices? And is organic food more nutritionally valuable?

This episode features Dr Marcin Barszczewski, Dr Aleks Marsh and Dr Alan Mullan discussing potentially scientifically contentious aspects of plant communication. We discuss what defines communication between plants? How can chemical signals be released from plants and detected by insects? Moreover, how can chemical signals be used to deter insect predators or promote pollination?

This episode features Dr Marcin Barszczewski, Dr Aleks Marsh and Dr Alan Mullan discussing how school starting age impacts on future success. In this episode we discuss what is success? And how can we measure it? In the age of big data are we asking the right questions, collecting the right data and reaching the right conclusions? Is school merely means to an end to being academically successful or is it a mechanism for intellectual, social and emotional development contributing to lifelong well-being?

In this episode Aleks and Alan interview Conor about vertical farming. Conor has built his own prototype vertical farm to grow wheatgrass - check out the image below! We ask Conor what is vertical farming? How much would crops produced from a vertical farm cost? And how much produce can we get with a vertical farm compared with traditional farming? With the threat of an unstable climate and the formation of megacities is vertical farming the future of farming?

This week Alan and Aleks interview a special guest, Dr Matteo Gallidabino, a Senior Lecturer in Forensic Science at Northumbria University. Several of Matteo’s recent papers have discussed the use of machine learning in forensic science. In this episode we ask Matteo, what is machine learning? How is it implemented in forensic science? Should we be worried – will machine learning replace the laboratory forensic scientist?

From the air we breathe, to the water we drink, to the food we eat, microplastics are everywhere. In this episode Dr Marcin Barszczewski, Dr Aleks Marsh and Dr Alan Mullan discuss what are microplastics and where are they from? How do plastics and microplastics impact marine environments and get in the food chain? And how does this impact us and the food we eat?

In this episode Dr Marcin Barszczewski, Dr Aleks Marsh and Dr Alan Mullan debunk common science claims which are actually fiction. Have you heard the common sayings that you only use 10% of your brain? Goldfish have a 3 second memory and that humans only have five senses?

All these claims are untrue but that leaves the following questions how much of our brains do we use? How long is a fish’s memory and how many senses do humans have? Find out in this episode

Coming Soon

This episode features Dr Aleks Marsh and Dr Alan Mullan interviewing guest Dr Michael Mullan - yes, we have Alan’s dad on the show! Michael is a food scientist with experience in industry, research and teaching in several areas of food manufacturing. Michael was a Lecturer in Food Technology at Queen's University Belfast for 19 years and is currently an independent Food & Beverages Professional.

In this episode we discuss what is pasteurization? How long does it take? What are the chemical and nutritional changes to milk on pasteurization? Finally, we ask Michael about the challenges facing dairy production today.

This episode features Dr Marcin Barszczewski, Dr Aleks Marsh and Dr Alan Mullan discussing the question how old is that apple?

Seasonal fruit and vegetable products are available year-round thanks to improved food preservation techniques which are prevalent in our supermarkets. This poses the question are preserved foods nutritionally as valuable? And what impact do preservation, storage and transport have on the taste and flavour of food?
