A small brain area may help decide which moments become lasting memories
Researchers recorded activity from individual brain cells in more than 100 surgical patients while they viewed new pictures, then tested later recall. Cells in the amygdala that responded to a particular kind of image, such as faces or landscapes, fired more strongly for pictures the person went on to remember. The work, published in Nature Neuroscience, points to a wider role for this region in forming everyday memories, beyond its well-known link to emotion.

Higher medical bills made people expect more pain — and hesitate to book care
Across three experiments, Carnegie Mellon researchers kept the medical procedure and its clinical details identical and changed only the out-of-pocket price. As the price rose, participants predicted more physical discomfort and became less willing to schedule the appointment. The researchers interpret this as financial worry spilling over into expectations of pain, with the effect strongest for people already under financial strain.

Daily peanuts were linked to a stronger brain insulin response in memory areas in older adults
In a small randomized crossover trial, 31 healthy adults aged 60 to 75 ate about 60 grams of unsalted, skin-roasted peanuts daily for 16 weeks, then switched to a no-peanut period. Brain imaging showed a stronger insulin response in a cluster of memory-related regions after the peanut period than after the control period. The study was small and funded by The Peanut Institute Foundation, which the researchers say had no role in the design or interpretation, so the result is best read as early evidence rather than dietary advice.
