This article presents 10 groundbreaking technologies across various fields. It explores the impact of AI, specifically generative-AI tools like ChatGPT, which have transformed the industry. The article also discusses the first gene-editing treatment for sickle-cell disease using CRISPR technology, offering hope for patients. Additionally, it delves into the use of heat pumps to decarbonize buildings and manufacturing, as well as the emergence of decentralized social media platforms as alternatives to Twitter. Enhanced geothermal systems are also highlighted for their potential to unlock more geothermal energy sources. The article further examines weight-loss drugs like Wegovy and Mounjaro, which are gaining popularity as potential solutions to the obesity crisis in the US. While these drugs can help individuals lose a significant amount of weight, they have side effects and are costly, often not covered by insurance plans. Nevertheless, weight-loss drugs have the potential to improve the health of many and alleviate symptoms of heart failure. [Extracted from the article]
