HR is no longer just about managing people—it’s about shaping the future of work. Jens Baier, BCG’s HR transformation expert, discusses how AI and shifting employee expectations are forcing companies to rethink talent strategies. From re-recruiting to upskilling employees, HR must adapt to a rapidly changing landscape.

Fun Paper Friday Summary:

In this episode’s Fun Paper Friday, we discuss B.F. Skinner’s “Pigeons in a Pelican.” The paper recounts the story of "Project Pigeon," a World War II experiment that explored using pigeons to guide missiles by pecking at visual targets. Though the project faced skepticism and was never implemented in combat, it highlighted the potential of animal training and laid a foundation for behaviorist research. The study is a testament to how creative ideas can push the boundaries of science, even if they seem outlandish at first.

45:27

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? 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. 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! Ou, Zihao, et al.

Throughout human history, certain minerals have held immense power, shaping economies, societies, and entire civilizations. In this economic rocks series, John and Shannon discuss how essential minerals like salt, gold, and coal influenced historical events and continue to impact modern geopolitics. This week we start with salt and how it is essential to many aspects of our day to day.

Fun Paper Friday This week's Fun Paper Friday features a study on the leaf-mimicking abilities of Boquila trifoliolata . The vine is capable of changing the shape and size of its leaves to resemble those of neighboring plants, potentially as a form of camouflage against herbivores. But the most surprising part? It can even mimic artificial plastic leaves. This finding challenges existing theories that leaf mimicry is driven solely by chemical signaling or genetic exchange between plants, suggesting instead that Boquila may possess a form of plant vision through specialized light-sensitive cells called “plant ocelli.” This discovery opens new possibilities for understanding plant sensory and adaptive behaviors.
