Artificial Intelligence Revolutionizing Medicine and Science
Artificial intelligence (AI) has made significant advancements in medicine and science. With the development of language models like chat GPT, AI is being used to streamline medical notes and patient records, generate correspondence between doctors and patients, and even draft messages from doctors to patients. However, there are concerns about the accuracy and potential biases of AI. In the field of science, AI is helping researchers in chemistry and biology by finding candidate molecules and compounds to test, and some labs have built robots capable of synthesis and testing. Despite these advancements, AI works best when humans are involved, complementing their skills and aiding in efficiency.
Climate Change and the Urgent Need for Action
Climate change remains a pressing concern, as 2023 is projected to be the hottest year on record. To prevent the most catastrophic effects, it is crucial to limit global temperature increases to 1.5 degrees Celsius compared to pre-industrial levels. However, we are currently not on track to achieve this goal, as greenhouse gas emissions need to be reduced by more than 40% by 2030. While it may not be a sudden cliff, every degree of temperature increase worsens the impact. Nonetheless, there are global efforts to address climate change, such as Uruguay's use of wind power to supply 98% of their grid's energy.
James Webb Space Telescope Revealing Surprising Discoveries
The James Webb Space Telescope (JWST) has provided astronomers with remarkable insights into the early universe. It has revealed previously unseen galaxies, black holes, and stars. Surprisingly, these celestial objects appear more developed than initially expected, challenging existing hypotheses. Since its science operations began, JWST has already detected the oldest known galaxy and black hole, hinting at the likelihood of more groundbreaking discoveries in the future.
2023 was filled with scientific innovation, exploration and new discoveries. A few of the biggest threads we saw unraveling this year came from the James Webb Space Telescope, the changing climate and artificial intelligence. Today, host Regina G. Barber wraps up these three areas of science news with the help of correspondent Geoff Brumfiel and All Things Considered host Ari Shapiro.
