TL;DR: A 2026 mouse study in Proceedings of the National Academy of Sciences found that deleting or inhibiting PTP1B improved memory behavior, reduced amyloid-beta burden, and pushed microglia toward an amyloid-clearing state. Key Findings Memory behavior improved: APP/PS1 mice lacking PTP1B performed better in novel object recognition and Morris water maze tests; the PTP1B inhibitor …
TL;DR: A 2026 study in Cognition & Emotion found that moral anger did not improve falsehood detection; it lowered the evidence threshold for sharing, making the choice faster and less dependent on source credibility. Key Findings Severe moral violations made false headlines more shareable: In a 223-person online experiment, people were more willing to share …
TL;DR: A 2026 study in Journal of Pain Research found dialysis headache in 50.6% of 79 adults receiving maintenance hemodialysis, with prior recurrent headaches and female sex independently linked to higher odds of developing headaches during dialysis. Key Findings 79 hemodialysis patients: Researchers interviewed adults with end-stage renal disease who had been on regular hemodialysis …
TL;DR: A 2026 Journal of Intelligence study of 170 adults found that math ability and music ability were only weakly related, and the link was reduced to almost zero after researchers accounted for general intelligence. Key Findings Adult ability groups were tested: The 170-person sample included math specialists, music specialists, and controls who did not …
TL;DR: A 2026 Imaging Neuroscience functional MRI (fMRI) study found that emotional pictures were recalled better than neutral pictures, but amygdala and insula activity appeared tied mainly to arousal rather than whether memories were negative or positive. Key Findings Large fMRI sample: The main imaging analysis used 1,006 healthy young adults from a single center. …
TL;DR: A 2026 double-blind trial in Psychopharmacology found that methylphenidate reduced cheating in healthy adults compared with placebo, contrary to survey respondents’ expectations about smart drugs. Key Findings Methylphenidate reduced dishonesty vs placebo: A double-blind placebo-controlled experiment in healthy adults showed methylphenidate (Ritalin) reduced cheating behavior compared to placebo — the opposite direction from what …
TL;DR: A 2025 study in The Journal of Prevention of Alzheimer’s Disease found that stress internalization, not acculturation or activity engagement, predicted memory decline across three waves in 1,528 older Chinese Americans. Key Findings Stress internalization predicted longitudinal memory decline: A latent factor combining greater perceived stress, greater hopelessness, and lower conscientiousness was the single …
TL;DR: A 2026 preprint registry-family study in medRxiv found that some maternal diagnosis-autism associations fit shared direct genetic effects, while other diagnoses showed stronger parallel-cousin associations, suggesting indirect genetic effects through the prenatal environment. Key Findings Study type: a three-generation Danish register study comparing full maternal parallel and cross cousin pairs. People studied: 1,131,899 children …
TL;DR: A 2026 Frontiers in Behavioral Neuroscience study reported that inaudible infrasound shifted mood toward unease and raised stress-hormone markers under controlled conditions, offering a physiological explanation for some room-specific fear sensations without supporting supernatural claims. Key Findings Inaudible infrasound shifted mood: Controlled exposure produced measurable mood changes — toward unease, anxiety, and a felt …
TL;DR: A 2026 MIDUS mediation study in Brain, Behavior, & Immunity – Health found that social asymmetry was associated with greater chronic disease burden, while chronic disease burden mediated links between social asymmetry and episodic memory and executive function, while allostatic load did not. Key Findings Study type: a structural equation modeling study of social …
