  • Ford Motor Company, in a joint research project with Microsoft, reveals a "quantum-inspired" algorithm able to cut traffic by 73% and shorten commuting times by 8% in a simulation of 5,000 cars.⁴⁹⁵⁴⁹⁶
• 11 December
  • Scientists report the discovery of cave art in central Indonesia that is estimated to be at least 43,900 years old, and noted that the finding was "the oldest pictorial record of storytelling and the earliest figurative artwork in the world".⁴⁹⁷
  • Researchers find evidence that the carbon dioxide concentration in the oceans rose before the asteroid impact that caused the extinction of non-avian dinosaurs. This was likely caused by long-term volcanic eruptions from the Deccan Traps and acidified the oceans already before the asteroid impact. Their results might inform preparations for consequences of contemporary human-caused climate change in the Earth system and were made possible by a new method for analyzing the calcium isotope composition of fossilized sea shells.⁴⁹⁸

The study could provide a low-cost way for a range applications for large-area flexible electronics.⁵⁰⁰⁵⁰¹
• 18 December
  • The CHEOPS space telescope, whose mission is to study the formation of extrasolar planets and determine their precise radius, likely density and internal structure, is launched.⁵⁰²⁵⁰³
