In today's episode of Discover Daily, we explore how Chinese military researchers have adapted Meta's open-source Llama model to create ChatBIT, an AI tool capable of performing at 90% of ChatGPT-4's capability. This development raises critical questions about the control of open-source AI technology and its potential military applications, with Meta's policy director explicitly stating that such military use violates their acceptable use policy.
We then uncover the fascinating secrets behind the Pantheon's 2000-year-old self-healing concrete, where recent MIT research reveals that special lime clasts created through "hot mixing" allow the ancient Roman structure to repair its own cracks. This discovery could reimagine modern construction methods and significantly reduce the environmental impact of concrete production, which currently accounts for 8% of global greenhouse gas emissions.
Lastly, we look at a new discovery about the sea walnut, a transparent comb jelly that can reverse its aging process when faced with stressful conditions. This extraordinary creature, which becomes only the third known species capable of age reversal, transforms from its adult form back to a juvenile stage by regrowing tentacles and adopting different feeding behaviors, offering potential insights into the biology of aging and regenerative medicine.
