A longitudinal MIDUS analysis involving 840 adults found that loneliness scores higher than a person's objective social-isolation score were linked to later cognitive impairment mainly through chronic disease burden, while the allostatic-load pathway was weaker than the chronic-disease pathway and not statistically confirmed for the main cognitive outcomes.1 Research Highlights Loneliness was separated from isolation: …
A 2026 controlled study of 96 people found severe long-COVID fatigue across 3 validated fatigue scales, but the tested peripheral inflammation, cellular-stress, neuroprotection, and autoimmunity markers did not significantly differ by group or explain fatigue severity.1 The finding argues against a simple blood-marker story, not against the reality of long-COVID fatigue. Research Highlights Fatigue was …
A 2026 PLOS One machine-learning study reported 95.0% accuracy for a hybrid FT-Transformer plus long short-term memory (LSTM) model predicting student mental-health risk. The technical result is strong inside the dataset, but the clinical claim is still limited because the labels came from repository data rather than prospective clinical diagnosis.1 Research Highlights 95.0% accuracy was …
A Wuhan cohort of 2,210 pregnant women found that mid-pregnancy sleep disturbance was common enough to screen for and associated with several birth-outcome signals. Depressive symptoms, pre-pregnancy alcohol use, and moderate-to-severe vomiting raised sleep-disturbance odds, while higher dietary variety was protective.1 Research Highlights 18.14% had sleep disturbance: Pittsburgh Sleep Quality Index (PSQI) scores greater than …
Nucleosomes may be far less uniform inside living chromatin than the textbook picture suggests. In a 2026 Nature study, a single-molecule method called IDLI found that more than 85% of sampled nucleosomes in mouse embryonic stem cells showed intranucleosomal DNA accessibility, meaning the DNA wrap was partly open or distorted rather than perfectly sealed around …
A 2026 analysis followed 161 people with cancer for 9 months to evaluate whether 2 forms of online mindfulness-based cognitive therapy reduced psychological distress: therapist-led group-blended care and individual self-guided modules. Psychological distress improved significantly in both formats, but fewer participants dropped out when the program included therapist-led group sessions. Research Highlights Distress improved through …
A 2026 study of Hodgkin lymphoma survivors treated with mantle radiation found obstructive sleep apnea (OSA) in 36 of 42 people who eventually underwent sleep testing. The practical screening target is a younger, non-obese, positional, hypopnea-heavy post-radiation OSA phenotype that standard risk heuristics can miss.1 Research Highlights Sleep symptoms identified a fatigued subgroup: 45 of …
