SPP1 Marks Cross-Disease Microglial Activation in Neurodegeneration

by GLOOM

MHD featured image for SPP1 microglia and neurodegeneration transcriptomics.

A 2026 Glia analysis found a shared microglial transcriptional program across 5 neurodegenerative contexts: ALS, frontotemporal dementia, Alzheimer’s disease, aging, and Parkinson’s disease.1 The standout marker was SPP1, a gene encoding osteopontin, but the finding is a cellular-state signal rather than a ready diagnostic test. Research Highlights Cross-disease microglia converged: the integrated dataset covered ALS, …

Amitriptyline Water Pollution Impaired Male Guppy Spatial Accuracy

by GLOOM

MHD featured image for amitriptyline water pollution and guppy spatial cognition.

A 2026 Environmental Science & Technology experiment found that wild guppies still reduced maze solve times with practice after 11-day exposure to environmentally motivated amitriptyline concentrations, but exposed males made 26.35% to 34.21% more navigation errors than control males.1 The result is a sex-specific accuracy signal, not a blanket claim that antidepressant pollution erased learning. …

Image Memorability, Not Recognition Success, Drove N400 Encoding Signals

by GLOOM

MHD featured image for image memorability and N400 EEG signals.

A 2026 EEG study found that image memorability predicted recognition strongly, z = 9.17, p < 0.001, and the N400 encoding signal tracked memorability after later recognition success was included in the same model.1 The result weakens the common shortcut that every hit-vs-miss brain signal is purely an encoding-success signal. Research Highlights Memorability predicted recognition: …

Depression Brain Energy Landscape Showed State 3 Trapping in MDD

by GLOOM

MHD featured image for depression brain energy landscape state trapping.

A 76-person Nature Communications fMRI study found that people with major depressive disorder spent a higher share of time in a model-derived State 3 than healthy controls, 27.63 vs. 25.65, p(FDR) = 0.035, and State 3 occupancy correlated with QIDS depression severity, r2 = 0.268, p(FDR) = 0.008.1 The result points to altered brain-state transitions …

Opioid Coalitions Used Data and Shared Goals to Expand MOUD/Naloxone

by GLOOM

MHD featured image for opioid coalitions and MOUD/naloxone implementation.

A 2026 qualitative case study of 8 top-performing HEALing Communities Study communities linked opioid-response implementation success to representative coalition membership, shared goals, data connectivity, and communications campaigns, not to a simple urban-vs.-rural split.1 The useful lesson is operational: coalitions worked when collaboration was turned into service reach for medication for opioid use disorder and overdose …

150 mg Caffeine Did Not Trigger Panic in Panic Disorder Trial

by GLOOM

MHD featured image for caffeine and panic disorder challenge research.

A randomized crossover trial found that 150 mg caffeine did not increase subjective anxiety, interoceptive attention, or anxiety from body sensations in 29 people with panic disorder compared with 53 healthy controls.1 The result runs opposite the hypothesis, but it does not make caffeine inert: caffeine still increased physiological arousal, costly avoidance, and attention problems …

CB1 Receptor Autophagy Did Not Explain p62 Obesity in Mice

by GLOOM

MHD featured image for CB1 receptor autophagy and p62 obesity mice.

A 2026 neuron and mouse study found that CB1 receptors accumulate when autophagic flux is blocked, but p62 deficiency did not significantly increase steady-state CB1 receptor abundance in brain or hypothalamus and did not make CB1 signaling the primary explanation for late-onset obesity.1 The result separates 2 claims that are easy to blur: CB1 can …
