For the inhabitants of Singapore this bizarre yet spectacular sight took a while to get used to. Architects have designed 18 synthetic 'supertrees' which, for the last few months have been acting as thermal storage systems and providing sha
de and nutrients - just like natural trees. Their shape allows them to collect rainwater and they're equipped with solar panels to store energy from the sun. A sophisticated system of channels, similar to the roots of a tree, ensures that all 200 plant species cultivated inside the supertrees are regularly watered.
When underwater photographer Yoji Ookata discovered these bizarre geometric sand circles off the coast of Japan, he was understandably pretty confused.
After returning to the site with colleagues and a television crew, they worked out that they're being made by male puffer fish. It's thought to be a 'display' to attract females and/or a shield to neutralize ocean currents that could pose a threat to their young.
