Goose Bump Technology
Researchers think goose-bumps probably reflect a distinct emotional state, a kind of awed mixture of fear and joy. English and French lack a word for this, but German has two.
Goose flesh, that rather odd form of emotional reaction in which a chill is felt and bumps form on the skin and the hairs stand erect, was noted by Darwin and still has scientists intrigued. Research into 'piloerection' had been hampered by the lack of an objective measure, until now. A new camera has found that film is a more reliable provoker of goose-bumps than music. "The researchers' conclusion is that given the low specificity of other physiological measures of emotion, measuring goose-bumps objectively could prove to be a useful new tool in the psychologist's armamentarium when studying emotional responses."

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
