A 2026 iScience study found that adults could learn a new auditory cue to visual depth after about 1 hour, but full perceptual integration did not appear reliably at the group level: only 31 of 63 participants, or 49%, gained precision when the novel cue was combined with familiar visual disparity.1 The sharp interpretation separates …
A 2026 NHANES mortality analysis found that adults with PHQ-9 depressive symptoms had lower long-term all-cause mortality when their CALLY index was higher: in the fully adjusted model, each 1-unit higher log-CALLY value carried a hazard ratio of 0.59, with a 95% confidence interval from 0.51 to 0.68.1 The useful interpretation is prognostic, not therapeutic: …
A 2026 population-based polysomnography study involving 1,206 adults found current smokers had 1.75x higher odds of worse obstructive sleep apnea severity than non-smokers or occasional smokers after adjustment for age and body mass index. Former smokers showed almost the same overall signal — 1.76x higher odds than never smokers — but that part of the …
A 2026 randomized sham-controlled trial in 76 adults with primary insomnia found an 8-week Sancai acupuncture protocol reduced post-treatment Insomnia Severity Index scores to 7.80 vs. 16.45 with sham acupuncture, while total sleep time increased to 366.83 minutes vs. 287.97 minutes.1 Research Highlights Insomnia severity fell far more with real acupuncture: Zhao et al. randomized …
A 2026 systematic review of 16 articles found that youth social-media suicide risk clustered around specific mechanisms, not raw screen time: emotional dysregulation appeared in 8 studies, social contagion or imitation in 6, and problematic social-network or gaming use in 4.1 Research Highlights Mechanisms beat screen-time panic: Martin-Calvete and Ramirez-Ucles screened 295 records, assessed 55 …
A 2026 DIVERGE analysis of 3,677 antidepressant-exposed patients with major depressive disorder in Pakistan classified 34% as treatment resistant, while 86% received psychotropic polypharmacy and only 6% received psychotherapy.1 The CYP2C19 signal is real enough to study prospectively, but the main treatment-system finding is medication stacking in a setting where psychological care was rare. Research …
A 2026 clinical-lab study tested a 77-drug liquid chromatography-tandem mass spectrometry serum screen in 1,021 patients and found that benzodiazepines accounted for 37.9% of all detections, ahead of antidepressants and antipsychotics.1 Emergency-department cases were a small slice of the sample, but they were positive more often than outpatients: 85.2% vs. 59.5%. Research Highlights Benzodiazepines dominated …
