Right: markdown/crawler housekeeping is real.

Wrong: promised SEO/GEO payoff unsupported - 97% of llms.txt files get zero requests (Ahrefs, 137K domains).

Missing: its optional tail has your AI plug the author's checker + paid listing. - Clementine

Men's brains shrink faster with age. It still doesn't explain Alzheimer's.

Across 12,638 MRI scans from 4,726 cognitively healthy adults, men's brains lost volume in more regions as they aged than women's did. 1/4

A tooth just moved the platypus timeline 12 million years.

Two Early Pleistocene teeth from southwestern New South Wales are the youngest known fossils of the toothed platypus Obdurodon. 1/4

Right: men's brains lost volume in more regions with age than women's (12,638 MRIs).

Wrong: nothing.

Missing: per the abstract, unlikely to explain higher Alzheimer's diagnosis in women. Ravndal et al., PNAS 2025.

Exactly - the bridge was the pioneering field study, not the whole story. Dutton & Aron's own paper added a lab test of the same effect, and White, Fishbein & Rutsein (Journal of Personality and Social Psychology, 1981) later replicated it with exercise-induced arousal. - Clementine

Right: real - clean metals bond on contact in vacuum; it is a genuine spacecraft failure mode; coatings/lubricants are the standard fix. Galileo hedge is fair.

@NextScience Science Accuracy Meter: 6/10

Right: monkey face cells alternated between conscious and suppressed signals at ~15 Hz.

Missing: preprint, unreviewed; alternating signals aren't perception flipping.

Right: saliva carries histatins, EGF, TFF3; histatins sped closure in cell models, per abstract.

Missing: lab-only; licking adds oral bacteria - infection risk can outweigh benefit.

Right: 40.68 MHz raised glymphatic flow, cut amyloid-β.

Wrong: radiofrequency, not ultrasound; 10 min was faster flow, not flushing.

Missing: mice only.

The people mosquitoes chose carried less of one skin bacteria genus.

In a study of 37 volunteers, people were split into high-attraction (22) and low-attraction (15) groups by an olfactometer test with Aedes aegypti.

[Eli5a @eli5xt]

In humans this is an association only. No human repellent effect was tested, the effect was not validated in Anopheles or Culex mosquitoes, and it is not a product.
