• 20 December – NASA scientists release the latest WMAP results and an image of the very early universe. The nine-year WMAP data shows "13.772+/-0.059"-billion-year-old temperature fluctuations and a temperature range of ± 200 microKelvin. In addition, the study finds that 95 percent of the early universe is composed of dark matter and energy, the curvature of space is less than 0.4 percent of "flat", and the universe emerged from the cosmic Dark Ages "about 400 million years" after the Big Bang.
• * As predicted by scientists, 21 December 2012 passes without any form of apocalyptic event, despite years of global anticipation.

• 24 December
• * Scientists analyse the genomes of individuals with a high familial risk of bowel cancer, and discover two flawed genes that may contribute to the disease.
• * American researchers report that their experiments with liquid crystals may yield future materials that can be directly controlled and re-shaped in real time.
• 26 December
• * The world's longest high-speed rail line enters operation in China. The railway links Beijing with Guangzhou.
• * Tigers, having been on the verge of extinction, are now making a comeback in India and Thailand, according to the Wildlife Conservation Society.
• 28 December – Stanford University engineers publish a design for a future mission to the Martian moon Phobos, incorporating both an orbiting satellite and spherical surface rovers.
• 31 December – A NASA-supported study suggests that manned spaceflight may harm the brains of astronauts and accelerate the onset of Alzheimer's disease.
