Pulsus paradoxus is an abnormally large drop in systolic blood pressure during inhalation. In most healthy people, systolic pressure falls by only a few millimeters of mercury when they breathe in. When that drop exceeds roughly 10 mm Hg, clinicians call it pulsus paradoxus. The name is misleading. The pulse does not actually disappear or … Read more
Ginger ale has been a home remedy for stomach trouble for generations, and Canada Dry is one of the most recognized names in that tradition.

Delta-9 THC is the main psychoactive compound in cannabis, and its potency varies enormously depending on the product, the route of administration, and how it is processed. Inhaled flower might deliver a fraction of the THC that a concentrated vape or edible does, and the same milligram can feel completely different depending on how it … Read more

Making liquid hydrogen means cooling hydrogen gas to minus 253 degrees Celsius (minus 423 degrees Fahrenheit), the point at which it turns from a gas into a liquid.
