Does magnesium improve sleep? An updated 2026 evidence review reveals modest trial effects, uncertain benefits, and a critical gap in baseline magnesium testing.

A personal guided meditation using regression-inspired imagery and inner-child visualization to explore safety, self-acceptance, eye contact, voice, and taking up space.
A three-day analysis of wearable-sensor data found a repeatable personal turning-direction bias. Turning direction was not convincingly related to falls or physical mobility, but a counterclockwise bias showed an exploratory association with better cognitive performance, echoing a 1992 visuospatial study.
Hormesis has one of the most attractive ideas in health science: a small stress can make a…
We live inside electric fields so quietly that it is easy to forget they are there. Between…
The 1918 Rosenau experiments famously failed to transmit influenza under the conditions used. That negative result is historically important, but modern human challenge studies show that influenza virus can reproducibly infect people, including by aerosol.
How acidic is the human stomach? Clinical pH measurements, 68-species comparisons and a surprising beaver exception reveal what stomach acid can and cannot tell us about evolution.
There is a strange natural phenomenon called the ant circle (also called death mill). A few ants…
GOS is one of the best-studied prebiotics; XOS is promising but less established. Here is how to read labels, judge claims, and avoid assuming that a GOS + XOS blend is automatically better.
Viruses and exosomes can look alike, but controlled infection and reverse-genetics experiments reveal a crucial difference. What host immunity and PCR really tell us.
