Tiny Matters

Matt Candeias, the host of In Defense of Plants, dives into the captivating world of plant pollination. He enlightens listeners on the bizarre strategies plants employ, like corpse flowers exuding foul aromas to attract specific pollinators. The discussion also touches on unique adaptations found in plants such as cycads and pawpaw trees, showcasing their intricate relationships with insects. Candeias advocates for planting native species, emphasizing their role in promoting biodiversity and enriching local ecosystems.

In this episode of Tiny Show and Tell Us, we cover why your body feels so ‘off’ at high altitudes and how we’ve evolved not to detect low oxygen levels but high amounts of carbon dioxide. Then we unpack the confusing world of molecule chirality — what it is, why it matters, and how we evolved to only have ‘left-handed’ amino acids but ‘right-handed’ DNA and RNA.We need your stories — they're what make these bonus episodes possible!

Explore how ancient teeth reveal the diets of megalodons and the migration patterns of woolly mammoths. Delve into the science of isotopes, tracing how nitrogen levels help understand prehistoric food webs. Learn about innovations in studying megalodon teeth that suggest they had a higher trophic level than great whites. Discover how strontium mapping from mammoth tusks reconstructs their life journeys across ancient landscapes. Plus, fascinating insights on the implications for conservation and potential de-extinction efforts!

In this episode of Tiny Show and Tell Us, we explore the science behind a very catchy headline about a drug that makes mice look more youthful and increases their life expectancies. Then we shift gears to talk about a predatory unicellular organism with a swan-like neck that rapidly extends a great distance to capture prey. Researchers used origami to understand the mechanics behind this anatomical feat. We need your stories — they're what make these bonus episodes possible!

Join Chris French, an expert in anomalistic psychology, and Vicki Webster-Wood, a leader in biohybrid robotics, as they explore the spectral and mechanical realms. French dives into the psychology of ghost sightings, examining how expectations and environmental factors mislead ghost hunters. He also discusses the intrigue of ghost-hunting gear. Meanwhile, Webster-Wood unveils the promises of biohybrid robots, from biodegradable actuators to using them for environmental monitoring, while emphasizing the ethical concerns of integrating human tissues in robotics.

Join science communicator Alex Danis as he unravels the surprising connection between algae and cloud formation. Discover how the tiny algae species Emiliania huxleyi can affect our skies by seeding clouds with their shells. The conversation also ventures into the immense galaxy walls, like the South Pole and Sloan Great Walls, stretching 1.5 billion light-years across the universe. Alex invites listeners to share their own science stories for a chance to be featured and win a special prize!

Ariana Remmel, a journalist and audio producer with a background in organic chemistry, dives into the intriguing world of pesticides. She discusses the historical context of pesticide use, including ancient practices and the introduction of DDT, highlighting Rachel Carson’s influence in the environmental movement. The conversation also explores fascinating coevolution between plants and pests, revealing how this natural dance informs modern pesticide strategies. Plus, Ariana shares insights on safer alternatives like biopesticides and the implications of genetically modified crops.

In this episode of Tiny Show and Tell Us, we talk about the ampullae of Lorenzini that allow sharks to detect the electrochemical signals coming from prey. We also cover the fascinating science behind cyanide-filled clovers. Did you know cyanide is actually a very popular poison in the plant kingdom?

E-cigarettes, commonly referred to as “vapes,” were invented in the early 2000s with the explicit goal of helping people quit smoking by transitioning them to something safer.  But there are many people, particularly in the United States, who start vaping without ever having smoked a cigarette, leading to fears that vaping will be an on-ramp to smoking — a “gateway drug.” In fact, in the U.S. alone, nearly half a million middle school students vape. And in 2019, the CDC started receiving reports of severe and acute lung injury in people who vaped. By February of 2020, almost 3,000 people had been hospitalized and 68 people had died. We know that smoking is deadly (in fact, it’s estimated to take about 10 years off your life), but of course vaping isn’t risk free. In this episode of Tiny Matters, we’ll dive into the science behind both to answer, “What’s more dangerous, smoking or vaping?” “And does vaping actually help people quit smoking cigarettes?” We’ll also get to the bottom of why so many people got sick or died from vaping back in 2019 and 2020, yet we haven’t seen injuries like that since.
