3. Meerkats are adorable creatures. They even starred in a show called Meerkat Manor on Animal Planet. But they are, by far, the most murderous species of any animal, killing more of their own species with greater frequency than any other animal, with almost 20% of meerkats being killed by one of their own. The average among all mammals is just 0.3%.
4. Parents of Sophie Turner, who played Sansa Stark in Game of Thrones, are separated. The first time her Dad ever visited her on set was the day they shot the Ramsay Bolton rape scene. The young actress had, meanwhile, been assured by the director that the scene would be “choreographed like a ballet” and would be “beautiful.”
5. Eyelash mites are parasites that live on the face and in the hair follicles of humans. Studies have shown that roughly a third of children and young adults, half of the adults, and two-thirds of elderly people were proven to be hosts of the Demodex mites. They feed on dead skin cells, but they apparently have also started taking a liking to mascara. Also, they don't have an anus. They still need to poo, so it's been said that they 'explode' with waste at the end of their lives and all the built-up waste degrades on your face.

Almonds contain so much of it that it gives them their typical taste and aroma. But don't worry. You would have to eat 5 kilograms at once to actually have any consequences.

While adding more liquid, there was a bright flash of Cherenkov radiation followed by gamma radiation alarms. In that split second, both men near the tanks were dead, their bodies just didn't know it yet. One man, Hisashi Ouchi, was kept alive for 83 days before his body finally gave out.

Many patients go six to nine months without sleep, during which time they develop dementia and become unresponsive. Death follows. It is incurable and untreatable. Inducing a coma still keeps the brain awake. Because it is a form of prion disease, similar to mad cow disease, it's irreversible even by genetic therapy because once the protein exists in the body, it will slowly transform healthy proteins into their prion form.
