Summary

This episode of ‘7 Days of Science’ presents a roundup of recent scientific news. The first story discusses a re-evaluation of Voyager 2 data from Uranus, suggesting that the planet’s extreme conditions observed in 1986 were influenced by a solar storm, potentially making its moons more habitable than previously thought. Next, a new species of ankylosaur, Huaxiazhoulong shouwen, is described from Late Cretaceous rocks in southern China. The main headline addresses the ‘Too Big to Walk’ hypothesis, which claims dinosaurs were too large to live on land; the video presents a published rebuttal by paleontologist Darren Naish, highlighting the overwhelming evidence for terrestrial locomotion in most dinosaurs. The show then covers the discovery of the oldest known intensive ochre mine in Eswatini, dating back at least 48,000 years. A DNA study of Pompeii victims reveals that previous assumptions about relationships and gender based on skeletal position and artifacts were often incorrect. The final news story reports on the devastating impact of avian flu on elephant seal populations in South America, with evidence of mammal-to-mammal transmission. The episode concludes with a new segment featuring Ben’s father, who reviews the citizen science project ‘Iguanas from Above’ and encourages viewers to participate.
