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.

Portraits and busts of all the “white male professors” have been removed from the part of Stockholm University, Sweden, which is dedicated to the study of Law.
Not only have they be removed, but they have also been replaced by artwork which apparently promotes “diversity”.
One of these is a drawing of a moose head colored with a rainbow.

40% of Palestinian Children Detained by Israel Are Sexually Abused: Virtually All Are Tortured
According to a new report by the independent, non-governmental, human rights organization the Palestinian Prisoners Club (PPC), at least 600 Palestinian children have been arrested in Jerusalem alone in the past five months. Of these, roughly 40% were sexually abused.
PPC attorney Mufeed al-Haj notes that this horrific, grotesque abuse is not the only crime of which the Israeli military is ...
Barbara Lerner Spectre On Twitter!
Kevin MacDonald writes in 2010:
In the video below, Barbara Lerner Spectre, who runs a government-funded Jewish study group in Sweden, makes the following remarkable statement—remarkable because she does not attribute anti-Jewish attitudes to irrational prejudices or even Muslims who hate Israel. Instead she says that it’s because of the “leading role” played by Jews in the movement toward multiculturalism:
