1. Artificial Intelligence: Artificial intelligence (AI) is a branch of computer science that aims to create intelligent machines that can perform tasks typically requiring human intelligence, such as visual perception, speech recognition, decision-making, and language translation. 2. Biotechnology: Biotechnology is the application of biological systems, organisms, or derivatives to develop products or processes that benefit society. This field encompasses a wide range of applications, such as genetic engineering, pharmaceuticals, agriculture, and environmental remediation. 3. Climate Change: Climate change refers to long-term changes in global or regional climate patterns, often attributed to human activities that increase greenhouse gas emissions. These changes can have wide-ranging impacts on ecosystems, weather patterns, and human societies, and efforts are underway to mitigate and adapt to these changes. 4. Machine Learning: Machine learning is a subset of artificial intelligence that involves developing algorithms and models that enable computers to learn from and make predictions or decisions based on data. Machine learning is used in a variety of applications, including predictive analytics, natural language processing, and computer vision. 5. Renewable Energy: Renewable energy refers to energy sources that are replenished naturally and can be used indefinitely without depleting finite resources. Examples of renewable energy sources include solar, wind, hydroelectric, and geothermal energy. The development and deployment of renewable energy technologies play a vital role in transitioning to a more sustainable energy system.
