When movies caught fire: The history and science of nitrocellulose film
Did you know that over 75% of silent films have disappeared? The culprit: highly flammable film! We open this episode of Tiny Matters with a poker bet, a decades long grudge, and a garage full of film before we hop into the rise of nitrate (nitrocellulose) film and how it shaped film history. We chat with Robert Shanebrook, who literally wrote the book on Kodak film, and with collection manager Deborah Stoiber at the George Eastman Museum, the world’s oldest photography museum and one of the oldest film archives. We talk about the science of preserving and conserving the nitrate films that have survived, and why it’s so important for keeping cultural memories alive.

[BONUS] Von Willebrand disease and how old is the air in your lungs?: Tiny Show and Tell Us #47
In this episode of Tiny Show and Tell Us, a listener asks: Could we still be carrying air from our very first breath? Deboki unpack’s residual lung volume, gas exchange, and a forensic technique used to determine whether or not someone drowned. Then, the conversation turns to women’s health and bleeding disorders after a listener shares their experience living with Von Willebrand disease — the most common bleeding disorder. Sam explores what the condition is, how it was discovered, why it disproportionately affects women, and how normalizing heavy, painful periods is not just frustrating but has serious medical consequences.Check out Pale Blue Pod here or wherever you get podcasts!We need your stories — they're what make these bonus episodes possible!

‘Clean beauty’: Cosmetics, chemophobia and the anti-vax pipeline
In the early 1930s, a “new and improved” eyelash dye called Lash Lure blinded more than a dozen women, ultimately forcing the FDA to pass new regulations on cosmetics. Nearly a century later, beauty remains far safer than it was in the past, but you could argue that beauty marketing has become far more insidious, with vague language and chemophobic claims to push consumers toward products. In this episode, we chat with cosmetic chemist and science communicator Michelle Wong to unpack the booming “clean beauty” industry, including a conversation about parabens and fragrances and how chemophobia (a fear of chemicals) early in life can become a gateway to broader anti-science thinking, including anti-vax. You can follow Michelle at @LabMuffinBeautyScience on Instagram, TikTok, and YouTube where she makes longer explainer videos.

[BONUS] The Chemists’ Wars: The Origin Story of Chemistry
Have you checked out ACS' new podcast Chain Reaction? Today we're bringing Tiny Matters listeners one of our favorite episodes! Chemistry doesn’t just shape conflict — conflict shapes chemistry. And at no time in history is that more apparent than during the two world wars. Historian Alison McManus recounts how the race to weaponize toxic gases like chlorine and mustard gas transformed chemists into key military players, spurred industrial growth, and ignited an international arms race during WWI. However, some battles of the world wars weren’t waged against an opposing army, but against diseases that soldiers caught while in combat. Journalist Karen Masterson reveals how WWII triggered a massive scientific mobilization — a secret, high‑stakes search for synthetic quinine and antimalarial drugs that would ultimately help seed the modern pharmaceutical industry. Packed with espionage, innovation, and ethical dilemmas, this episode uncovers how war accelerated chemistry in ways that still shape science today.Available wherever you get podcasts!

[BONUS] Antarctic dinosaurs, blood restriction therapy, and an HIV prevention breakthrough: Tiny Show and Tell Us #46
In this episode of Tiny Show and Tell Us, we welcome our first‑ever guest, podcast producer and dinosaur enthusiast Steven Ray Morris. Together, we dive into three wildly different stories. First, we explore a major advancement in HIV prevention: a newly approved twice‑yearly injectable drug called Lenacapavir. We chat about how it works, why it’s a huge shift from daily pills or monthly shots, and the challenges around global access. Next, Steven takes us deep into the (mostly chilly) past — to Antarctic dinosaurs! What scientists are learning about these dinos is shifting what we think we know about where, and how, dinosaurs lived. Finally, Deboki breaks down the science behind blood flow restriction therapy, a rehabilitation technique that helps injured muscles rebuild strength using lighter loads. As always, Tiny Matters is not giving anything that could be interpreted as medical advice! Deboki also reveals she’s into weightlifting. So yeah, don’t mess with Deboki!

Deep-sea mining: Environmental uncertainty, ‘Law of the Sea,’ and shark potatoes
In this episode, we dive into the murky, high‑stakes world of deep-sea mining — the practice of extracting valuable metals from the ocean floor. Deep-sea mining has been “just around the corner” for decades. So what’s the holdup? With the help of deep-sea ecologist Andrew Thaler and oceanography researcher Michael Dowd, we discuss what makes the deep ocean such a challenging place to operate, and unpack why polymetallic nodules have drawn so much interest, and why removing them could permanently alter ecosystems we barely understand. The episode also looks ahead, asking whether deep-sea mining is even necessary and what it could mean not just for Earth’s oceans, but for future resource extraction in places like Antarctica and the Moon. It’s a story about science, but also Victorian research ships, CIA cover stories, “shark potatoes,” and vast, untouched ecosystems.

[BONUS] The history of Turner Syndrome and engineering food for bees: Tiny Show and Tell Us #45
In this episode of Tiny Show and Tell Us, we trace the history of Turner Syndrome — from early clinical observations to the discovery of its chromosomal cause — highlighting how scientists began connecting symptoms to genetics long before DNA was fully understood. Then we follow up on a listener note about lab safety by explaining, at a molecular level, why dimethylmercury and prions are so dangerous to the human body. Ending on something more hopeful, we explore new research showing how engineered yeast could help give honey bees the nutrients they need to thrive.
