**A brain scan may not reveal how well someone handles tough emotions**
A large pooled analysis brought together 40 brain-imaging datasets covering up to 2,175 people who were asked to rethink upsetting pictures in a less distressing way while in a scanner. Activity in the front-of-brain areas usually tied to this reframing skill did not predict how well each individual actually managed their feelings, and three common gauges of that skill — a self-report questionnaire, in-scanner mood change, and change in a deep emotion-processing region — lined up only weakly with one another. The authors conclude that comparing brain activity across people is far less straightforward than comparing it within one person, and that single-region readings should not be treated as a personal score for emotional control.

**When you eat may track with how sharp your memory is**
In an observational study of middle-aged and older adults, researchers compared questionnaire reports of daily eating rhythms with scores on memory and attention tests. More frequent meals, extra snacking, eating at night, and stretching food intake across a longer stretch of the day were all tied to lower memory scores, while waiting longer after waking before the first meal was tied to weaker overall thinking, and leaving a longer gap between the last meal and bedtime was tied to stronger memory and thinking scores. Because the study captured patterns at one stage rather than testing a change in habits, it shows links only — not proof that shifting meal times would protect thinking.

**Writing about thanks did no better than simply writing freely**
In a randomized experiment, 198 university students were assigned to one of three short writing tasks: one prompting gratitude, one prompting a sense of indebtedness, and one allowing free expression as a comparison. The indebtedness group reported lower positive mood and higher negative mood than the other two groups, while the gratitude group ended up no better off than the free-writing group, suggesting the act of writing itself may carry the benefit. The results cover immediate mood after a single task in students only, so they say nothing about the longer-term effects of a regular gratitude habit.
