Six Minute Science
Six Minute Science, produced and hosted by KTNA’s Jenny Willoughby, promises to be a weekly cram session of everything weird and wonderful about science. We’ll learn about fire, mushrooms, octopuses, and much more this season. Tuesdays at 12:30pm after the midday news and on Saturdays after Ag Matters at about 6:25pm on KTNA.

Episode 1: Morels and Fire
Episode 2: Octopuses and Antarctica
Episode 3: Redwoods and Fire
Episode 4: Microplastics
Episode 5: Garbage Patch
Episode 6: Snakeworms
Episode 7: Magma
Episode 8: Ice Fog
Episode 9: No Summer
Episode 10: Arctic-breeding Shorebirds
Episode 11: Iron Lead and Glacial Dust
What’s so important about the iron and lead scientists have found in the glacial dust? Airplanes and food webs and melting glaciers, oh my!
Episode 12: Caterpillar Mimicry
Why caterpillars in Alaska look like snakes, which aren’t found in Alaska. And how climate change is impacting butterflies.
Episode 13: Tidepools
What a tidepool is, who lives there, and how they might be changing.
Episode 14: Aurora
What the Aurora Borealis is, how it happens, how it gets its color, and if it makes a sound.
Episode 15: Canada Lynx
Canada lynx, what makes them able to live in Alaska, and new research on their travel patterns
Episode 16: Microplastics on Denali
Two University of Alaska Fairbanks students collected samples for microplastics on their way to the summit of Denali. So far, their research shows microplastics are even on North America’s highest peak.
Episode 17: Cogeneration
Cogeneration is a newer way to recognize efficiencies and resilience in energy generation and usage. The Ted Stevens Anchorage International Airport will build one of these facilities in the very near future.
Episode 18: Wildfire Seasons
Wildfire is pushed by different factors depending on when they happen during the season. And trends are showing the fire season is getting longer.
Episode 19: Barnacles
Barnacles are one of those weird critters that have a two-part life cycle, but also seem to be more resilient in warming water. Recent research shows they take advantage of any bare spots on rocks left by things that can’t hang in the rising water temps.
Episode 20: Wildfire Air Quality
Wildfire smoke is a concern for air quality, but new research shows that intense wildfires generate more particulate matter higher in the atmosphere rather than on the ground.
Episode 21: Fossils and Sediment
Dinosaur tracks abound in the Yukon Delta, but recently they also found some very large bird tracks, indicating some interesting things about the life that the Delta has supported over millions of years.
Episode 22: Bar-tailed Godwits
Bar-tailed godwits travel about 20,000 miles each year reaching three different continents, with a summer stopover in Alaska to fatten up and raise babies. And a bar-tailed godwit holds the record for the longest non-stop flight known to science.
Episode 23: Atmospheric Energy
Non-visible atmospheric energy may not be as pretty as the Aurora, but it can have a big impact on everything from telecommunications to carbon dioxide.
Episode 24: Invasive Species Risks
Invasive species can become problematic for our ecosystems and even us, but there are a few things we can all do to reduce their spread.
Episode 25: Volcanos and Earthquakes
Alaska has a lot of volcanoes and earthquakes-more than any other state. And they are linked, but do earthquakes actually trigger volcanic activity?
Episode 26: Earth MRI in the Kuskokwim
Through the Earth MRI program, scientists collect data about where mineral resources are located and what those minerals might be and the Kuskokwim data will be collected with aeromagnetic surveys.
Episode 27: Pesticides in the Environment
Some persistent pesticides are especially helpful with managing invasive plants that have long-lived seeds. Knowing which one will be the best for certain applications is key.
Episode 28: Pollinators and Plant Preference
New research is showing that invasive plants just aren’t attractive to many pollinators the way that native plants are
Episode 29: Phytoremediation
Get into the nuts and bolts of phytoremediation, or using plants to clean up contaminated sites.
Episode 30: Stream Scour
Learn about what scour is, how it affects bridge piers, and all the equipment used to measure it.
Episode 31: Mount Churchill
Learn about the history of Mt. Churchill and what its past eruptions can tell us about how a new activity could impact us if it erupts.
Episode 32: Microbes in Winter
What a microbe is and what it does, even in winter, and how they help with the carbon dioxide battle.
Episode 33: Ants
ANTS! It’s all about how they live, how they fit into the ecosystem, and why it’s so hard to identify them.
Episode 34: Black Brants
Black brants, which are a special kind of geese, their migration patterns and habitats.
Episode 35: Glacier Trash (Poop) Revisited
Glacier trash, how it travels in the glacier, and what it could mean for water quality.
Episode 36: Remote sensing for bark beetle infestation.
Tracking spruce tree deaths using multiple remote sensing methods.
Episode 37: Songbirds at the Alaska Songbird Institute
This episode is about the data collection efforts at the Alaska Songbird Institute.
Episode 38: Beavers and Poplars
This episode is about beavers moving north and what impacts they may have on tundra poplar groves.
Episode 39: Microbes in Permafrost
This week’s episode is about microbes in melting permafrost.
Episode 40: Mendenhall Glacier
This episode is about the Mendenhall Glacier, its retreat, and its flooding.
Episode 41: Tularemia
This episode is about Tularemia, what it is, and how it can affect wildlife, humans, and our pets.
Episode 42: ACORN
This episode gives an update on ACORN – Alaska’s Continuously Operating Reference Network. The State’s ACORN system has expanded westward, and brings a lot more capabilities that will help keep data collection efforts on a consistent system and help with planning and development too.
Episode 43: Ice Pillars
This week’s episode is about ice pillars, how they form, and where to see them.
