Ayahuasca, a traditional Amazonian brew known for its psychedelic effects, appears to enhance certain aspects of memory, according to a recent study. This memory boost was selective, as it did not increase false memories or their general feeling of familiarity with the scenes.

Just a few days of eating a diet high in saturated fat could be enough to cause memory problems and related brain inflammation in older adults, a new study in rats suggests. The results dispel the idea that diet-related inflammation in the aging brain is driven by obesity, researchers say.
