In this episode of 'Chemistry for Your Life,' hosts Melissa and Jam explore the chemistry behind the popular belief that eating carrots improves night vision. They take a deep dive into the scientific processes, including how beta carotene from carrots is converted into vitamin A, then into rhodopsin, and how this helps with night vision. They also discuss the historical context of this belief, dating back to World War II propaganda, and expand their discussion to include other fall foods rich in beta carotene, such as pumpkins and sweet potatoes. The episode also touches on fun facts, personal anecdotes, and a special shout-out to a new community member.

New College-Style Sweatshirt! And Spooky Chemistry Shirts Are Back!
Melissa and Jam explore the fascinating chemistry behind self tanners. They take listeners on a journey from the discovery of the key sugar in self tanners in the 1960s by Dr. Eva Wittgenstein to the present-day scientific understanding. The episode delves into the Maillard reactions, typically known for browning food, explaining in simple terms how similar reactions color the skin when self tanners are used. Additionally, the hosts discuss the molecular structure of carbohydrates, the generation of free radicals, and the temporary UV sensitivity following self-tanner application. Interactive elements like pop quizzes and listener shout-outs keep the discussion engaging and educational, while also touching on recent studies and encouraging community support. The episode is a blend of fun facts, thorough biochemistry, and practical advice for achieving a safe, sun-kissed look.

A podcast that helps you understand the fascinating chemistry hidden in your everyday life.
Have you ever wondered why onions make you cry? Or how soap gets your hands clean? What really is margarine, or why do trees change colors in the fall? Melissa is a chemist, and to answer these questions she started a podcast, called Chemistry for your life!
In each episode Melissa explains the chemistry behind one of life’s mysteries to Jam, who is definitely not a chemist, but she explains it in a way that is easy to understand, and totally fascinating.
If you’re someone who loves learning new things, or who wonders about the way the world works, then give us a listen.
