A December 2025 study of more than 30,000 older adults found that social isolation accelerated cognitive decline whether people felt lonely or not — and only 6% of the effect could be explained by loneliness itself.
3+ week, 3+ day ago (855+ words) A 30,421-person study separated objective social isolation from subjective loneliness and estimated that loneliness mediated only 6 percent of isolation's cognitive effect.

Microsoft's AI diagnostic system correctly solved up to 85.5% of 304 exceptionally difficult medical cases adapted from the New England Journal of Medicine — while 21 experienced physicians averaged just 20% under the same benchmark conditions.
4+ week, 1+ day ago (799+ words) Microsoft's diagnostic orchestrator posted a striking result on 304 rare medical puzzles, but the benchmark was text-based, the work remains a preprint, and revised figures differ.

A 2025 study in Scientific Reports found that pet owners who leaned on animals as a substitute for human company were not less lonely for it; the substitution itself was linked to more loneliness, and that loneliness explained the drop in wellbeing
1+ mon, 2+ day ago (770+ words) ScienceBlog.com Jaining Li and Nichol Wong, at the Education University of Hong Kong, published a study in October 2025 in Scientific Reports that looked at exactly this pattern, pet owners who lean on animals specifically in place of people, and…...
The claim that the nicest people end up the loneliest has spread widely this year, and the largest meta-analysis on personality and loneliness, covering 93,668 people across 113 studies, points the other way
1+ mon, 1+ week ago (717+ words) A meta-analysis of 113 studies and 93,668 people finds agreeableness is associated with less loneliness, not more. The popular claim describes a narrower pattern that researchers measure separately, and the evidence for it stops short of where the claim goes. By Science…...
Exosomes, Hypothalamus, and the Body Clock

The blood-brain barrier lets glucose and ketones cross freely, but blocks 98% of small-molecule drugs — and the tight junctions doing the filtering are only about 4 nanometers wide
1+ mon, 3+ week ago (789+ words) The endothelial cells lining the blood vessels of your brain are stitched together so tightly that the gaps between them measure roughly 4 nanometers — about the width of a strand of DNA, and small enough to exclude more than 98% of every…...
Scientists identify a cell type in the brain that was previously ignored and it may explain why human memory has no known upper limit
1+ mon, 4+ week ago (192+ words) For nearly two centuries, neuroscience has been telling a story about the human brain that centres almost entirely on one kind of cell. The neuron — the...
A Parkinson's-linked protein can spread from cell to cell, and Yale researchers found the two-protein complex that appears to help it get inside neurons and trigger damage
1+ mon, 4+ week ago (717+ words) A protein associated with Parkinson's disease can move from one brain cell to another. Yale researchers have now identified an interacting pair of...
