Humans glow in the dark
Ultra-sensitive cameras reveal that our bodies emit tiny amounts of light that are too weak for the human eye to detect
Amazing pictures of "glittering" human bodies have been released by Japanese scientists who have captured the first ever images of human "bioluminescence".

Although it has been known for many years that all living creatures produce a small amount of light as a result of chemical reactions within their cells, this is the first time light produced by humans has been captured on camera.
Writing in the online journal PLoS ONE, the researchers describe how they imaged volunteers' upper bodies using ultra-sensitive cameras over a period of several days. Their results show that the amount of light emitted follows a 24-hour cycle, at its highest in late afternoon and lowest late at night, and that the brightest light is emitted from the cheeks, forehead and neck.
Strangely, the areas that produced the brightest light did not correspond with the brightest areas on thermal images of the volunteers' bodies.
The light is a thousand times weaker than the human eye can perceive. At such a low level, it is unlikely to serve any evolutionary purpose in humans though when emitted more strongly by animals such as fireflies, glow-worms and deep-sea fish, it can be used to attract mates and for illumination.
Bioluminescence is a side-effect of metabolic reactions within all creatures, the result of highly reactive free radicals produced through cell respiration interacting with free-floating lipids and proteins. The "excited" molecules that result can react with chemicals called fluorophores to emit photons.
Human bioluminescence has been suspected for years, but until now the cameras required to detect such dim light sources took over an hour to capture a single image and so were unable to measure the constantly fluctuating light from living creatures.
While the practical applications of the discovery are hard to imagine, one can't help wondering what further surprises the human body has in store for us.

Better Identification of Viking Corpses Reveals: Half of the Warriors Were Female
Shieldmaidens are not a myth! A recent archaeological discovery has shattered the stereotype of exclusively male Viking warriors sailing out to war while their long-suffering wives wait at home with baby Vikings. (We knew it! We always knew it.) Plus, some other findings are challenging that whole ârape and pillageâ thing, too.
Researchers at the University of Western Australia decided ...

Into Eternity - Finland's 100,000 Year Massive Underground Spent Nuclear Fuel Program
Into Eternity is a documentary about a deep geological repository for nuclear waste. The concept of long-term underground storage for radioactive waste has been explored since the 1950s. The inner part of the Russian doll-like storage canisters is to be composed of copper. Hence in the case of Onkalo it is tightly linked to experiments on copper corrosion in running ...
