In July 2010, amid the gargantuan rebuilding effort at the site of the World Trade Center in Lower Manhattan, construction workers halted the backhoes when they uncovered something unexpected just south of where the Twin Towers once stood.

Teeth rows of a tiger shark (Galeocerdo cuvier). Often times the teeth of a shark are the only evidence of that species’ existence in the fossil record - their cartilaginous skeletons fail to preserve with the same frequency. These teeth, however, are not bone - they’re modified placoid plates; in other words, scales.
Dragonfly helmet, made in Japan in the 17th century (source).
High-ranking lords began to embellish their helmets with sculptural forms so that they could be visually located on the battlefield. Exotic helmets (kawari kabuto) also allowed leaders to choose symbolic motifs for their helmets that reflected some aspect of their personality or that of their collective battalions. This helmet is shaped like a giant dragonfly. In Japan, the dragonfly is symbolic of focused endeavor and vigilance because of its manner of moving up, down and sideways while continuing to face forward. In addition, in ancient texts Japan was often referred to as Akitsushima (Land of the Dragonflies), because of their abundance. They were also thought to be the spirits of rice, since they are often to be found hovering above the flooded rice fields. - from the Minneapolis Institute of Arts description
Scottish universities should appoint more women to their governing bodies or be forced to do so, according to the National Union of Students.
NUS Scotland says the boards are dominated by men and the proportion of women is far too low.
A new voluntary code last year committed universities to improving the boards’ equality and diversity.
The body that represents universities says progress is being made and is confident more women will be appointed.
NUS Scotland argues that, if universities cannot meet their own commitments to improving the diversity and gender balance of boards, legislation should be introduced to make this mandatory.
Vonnie Sandlan, NUS Scotland women’s officer, said: “It’s incredibly worrying that, despite committing to strengthening the gender balance in their governing bodies, so many universities are still lagging behind. This is clear evidence that self-regulation does not seem to be enough to bring about gender equality on the boards that run our universities.”
