Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

We humans could have a bright future ahead of us that lasts billions of years. But we have to survive the next 200 years first. Join Josh Clark of Stuff You Should Know for a 10-episode deep dive that explores the future of humanity and finds dangers we have never encountered before lurking just ahead. And if we humans are alone in the universe, if we don't survive intelligent life dies out with us too.

Ever wondered how geologists figure out when a landslide happened? Or how ancient river terraces and glacial deposits get dated? This week, we dive into the detective work behind dating geomorphic features! 🌍🔬 From tree rings to cosmic rays, we explore the fascinating methods geologists use to reconstruct Earth’s history and assess natural hazards.
Why Dating Landslides and Other Features is Hard
- Landslides can reactivate multiple times, fluvial deposits get reworked, and glacial features have complex histories.
- What are we really dating—the event, the material, or the last exposure?
- Landslides can reactivate multiple times, fluvial deposits get reworked, and glacial features have complex histories.
Dating Techniques in Geology
- Dendrochronology 🌲 – Tree rings reveal landslides, floods, and debris flows.
- Radiocarbon Dating 💀 – Organic material like charcoal and buried soil horizons provide time markers.
- Optically Stimulated Luminescence (OSL) 🌞 – Measures when quartz grains were last exposed to sunlight.
- Cosmogenic Nuclide Dating ☄️ – Tracks surface exposure using cosmic rays.
- Other Methods – Lichen growth, volcanic ash layers, and earthquake trenching.
- Dendrochronology 🌲 – Tree rings reveal landslides, floods, and debris flows.
Fun Paper Friday
Ever wondered if your favorite neon-orange snack has hidden superpowers? This study explores how strongly absorbing molecules, like those found in food dyes, can reduce light scattering in biological tissues—making them temporarily more transparent! Researchers applied tartrazine (a common food coloring) to live mice and were able to see internal structures like blood vessels without invasive procedures. The discovery could improve biomedical imaging, but we’re mostly just fascinated that Dorito dust might have unexpected side effects!
