Modern cosmology believes that for the universe to behave as it does, the mass-energy of the universe must be dominated by dark matter and dark energy, though there is no direct evidence for the existence of these invisible components.    Alternate, though unpopular, possibilities are that the current theory of gravity does not suffice to describe the dynamics of cosmic systems.
Athletes will always look for a competitive edge and 'natural' performance enhancements that can escape scrutiny are a frequent goal.    Scientists have found that bovine colostrum can massively reduce gut permeability, otherwise known as 'leaky gut syndrome' and the results may also be applicable to sufferers of heatstroke.

Gut disorders induced by exercise are common in runners; the body's response to increased permeability is to clear the gut contents, giving rise to symptoms such as diarrhea to avoid toxins from gut organisms entering the bloodstream, as these lead to heatstroke which can result in damage to the internal organs.
