Sally Lightfoot Crab- Grapsus grapsus is a typically shaped crab, with five pairs of legs, the front two bearing small, blocky, symmetrical chelae. The other legs are broad and flat, with only the tips touching the substrate. The crab’s round, flat carapace is slightly longer than 8 centimetres (3.1 in). Young G. grapsus are black or dark brown in colour and are camouflaged well on the black lava coasts of volcanic islands. Adults are quite variable in colour; some are muted brownish-red, some mottled or spotted brown, pink, or yellow. (sources 1,2)

Harvard discovers three of its library books are bound in human flesh

As it turns out, the practice of using human skin to bind books was actually pretty popular during the 17th century. It’s referred to as Anthropodermic bibliopegy and proved pretty common when it came to anatomical textbooks. Medical professionals would often use the flesh of cadavers they’d dissected during their research. Waste not, want not, I suppose.

A new formula helps CSIs determine whether a victim took a blow standing up.
1// Height of the blood at the beginning of its parabolic arc, that is, when it left the body.
2// Tangent of the angle at which the first blood drop hit the ground.
3// Tangent of the angle at which the second drop hit the ground.
4// Horizontal distance the first drop traveled.
5// Horizontal distance the second drop traveled.

At TEDxYouth@Manchester, genetics researcher Dan Davis introduces the audience to compatibility genes — key players in our immune system’s functioning, and the reason why it’s so difficult to transplant organs from person to person: one’s compatibility genes must match another’s for a transplant to take.

To learn more about these fascinating genes, watch the whole talk here»
