A survey on the experience of auditory hallucinations, commonly referred to as hearing voices, found that the majority of voice-hearers hear multiple voices with distinct character-like qualities, with many also experiencing physical effects on their bodies.

In other words,voices in people's heads may be more varied and complex than previously thought. Or they are so subjective as to defy science.

Auditory hallucinations are a common feature of many psychiatric disorders, such as psychosis, schizophrenia and bipolar disorder, but are sometimes experienced by people without a diagnosed psychiatric condition.

Ritalin, Adderall and their ilk are Schedule II controlled substances - the same as cocaine and methamphetamine - but they are widely available on college campuses, thanks to the ADHD diagnosis craze that made prescriptions easy to get and prevalent starting in the 1990s.

Because rosacea affects facial appearance, it can also have a psychological impact on those who suffer from it, according to surveys by the National Rosacea Society.

A new injectable polymer  called PolySTAT strengthens blood clots and that means that  soldiers who might otherwise die from uncontrolled bleeding before reaching a surgical hospital could be saved. Likewise for civilian traumas.

A tourniquet won't stop bleeding from a chest wound, and clotting treatments that require refrigerated or frozen blood products aren't always available in the field.
