The episode examines what happens chemically when cooked starch cools and is reheated. Melissa and Jam discuss glucose polymers, insulin, digestion, crystallization, resistant starch, and interactions with gut microbes. They review studies involving foods such as bread, rice, pasta, and potatoes, and explore the proposed effects of repeated reheating. The discussion connects everyday cooking questions to food chemistry and the evidence behind claims about leftovers.

Mariana Kneppers, Frankie Macpherson and Phillip Broadwith discuss allegations about manipulated antibody-validation images in Thermo Fisher Scientific's catalogue and the questions they raise for research integrity. They also examine the technical and commercial difficulties facing chemical recycling of plastics.

Monther Abu-Remaileh examines the cell's recycling machinery and its possible role in neurodegeneration. He explains how lysosomes process cellular material, why failures in that system can affect neurons, and how studying this biology may reveal connections among protein accumulation, aging and brain disease.
