I have an idea of the thrust of the news between now and Christmas. It may be a good time to talk about philosophy of science.
What we learn in our high school science classes about the nature of scientific progress is that it comes brick-by-brick. We learn that scientists form hypotheses, devise experiments to test them, collect data, form conclusions, around and around. Their results and conclusions are bricks that get added to the wall of science, a wall that gets built higher and higher over time with each generation of scientists.
