In this episode of Curiosity Weekly, Dr. Samantha Amin explores three groundbreaking scientific frontiers. First, she examines 'Humanity's Last Exam,' a rigorous 2,500-question test designed by nearly 1,000 global researchers to assess whether AI can match human expertise. The results show AI models like Gemini 3.1 Pro scoring only 50% accuracy, with most models around 5%, highlighting that human intuition, context, and specialized knowledge remain unmatched. Next, Amin dives into the discovery of Spinosaurus mirabilis, a newly identified dinosaur species found in the Sahara Desert by paleontologist Dr. Paul Serino. Using drones, photogrammetry, and solar-powered tech, Serino’s team uncovered a land-adapted, fish-eating spinosaur with a towering crest and interdigitating teeth—evolutionary adaptations for catching slippery prey. The find reshapes our understanding of dinosaur behavior and evolution, suggesting a unique 'hell heron' niche in ancient river systems. Finally, the episode reveals a neuroscience breakthrough: in mice, consistent exercise rewires the brain’s ventromedial hypothalamus, specifically SF1 neurons, which are essential for building endurance. Post-exercise activation of these neurons triggers physiological changes, proving that brain rewiring is not just a side effect but a necessary mechanism for stamina gains. The episode underscores the power of human curiosity, collaboration, and the unseen role of the brain in physical performance.
AI still lags behind humans in complex, context-rich tasks—'Humanity's Last Exam' proves that advanced models struggle with graduate-level, non-searchable questions requiring deep expertise.
Spinosaurus mirabilis was a land-adapted, fish-hunting dinosaur with unique interdigitating teeth and a towering crest, challenging previous assumptions about spinosaurs being marine animals.
Paleontological discoveries rely on modern tech like drones, photogrammetry, and solar-powered computing, enabling high-resolution digital reconstruction of fossils in remote environments.
Local knowledge and international collaboration—especially with Tuareg guides like Abdu Nassar—are essential for successful fieldwork and ethical research in regions like the Sahara.
The brain plays a direct, causal role in building endurance: post-exercise rewiring of SF1 neurons in the hypothalamus is required for physiological gains, not just psychological grit.

Welcome to Curiosity Weekly
Host Dr. Samantha Amin introduces the podcast, previews the episode's three segments, and encourages listeners to rate and review the show.
Humanity's Last Exam: Can AI Pass?
“In human vs machine, humans still wins. For now. Phew!”
The Discovery of Spinosaurus mirabilis
“We have a hell heron on our hands, something that... no marine animal like a whale or a mosasaur ever lived up the rivers that was even half the size of Spinosaurus.”
The Science of Endurance: Brain Rewiring
“No brain, no gain.”
Closing Notes and Credits
The episode concludes with production credits and a brief thank-you to listeners.
“We have a hell heron on our hands, something that... no marine animal like a whale or a mosasaur ever lived up the rivers that was even half the size of Spinosaurus.”
“In human vs machine, humans still wins. For now. Phew!”
“If you don't have the scholars, the museums, the storerooms, the knowledge and the understanding of the importance of these finds, they will eventually be destroyed.”
