Every year, scientists make amazing new discoveries ¡ª findings that often don¡¯t get the attention they deserve.

War, tragedy and political controversies understandably dominate social media and the front pages, but not all the news is bad. With 2023 having drawn to a close, let¡¯s look back on some of the astounding breakthroughs we¡¯ve seen in the last 12 months.
