Tiny Matters

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!

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.

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. Team bees!
