32. Organ on a chip
Researchers at the Wyss Institute have developed a system for replicating complex, 3-dimensional tissues in the human body using circuitry combined with living cells. These proxy-organs will facilitate rapid, sophisticated testing without the need...
33. Bioinspired adhesive tape
Insects are well known for their ability to walk with ease on vertical surfaces, rough or smooth, and scientists have long been looking for ways to reproduce those abilities. A team of researchers from the Max Planck Institute joined with a team o...
34. Reflectance causes white color: cabbage butterfly
"The small white, P. [Pieris] rapae, offers an interesting example of the biology of wing coloration. Both sexes of this butterfly species are rather featureless for human eyes, except for slight differences in the black spots, small wing areas wh...
35. Screw-and-nut leg joint assists climbing: Papuan weevil
"It is remarkable that in the case of the weevil leg a rotary movement is accomplished by a screw-and-nut system. In engineering, such systems are mainly used for fixing connections, whereas an axle would be used for a simple rotation. The possibl...
37. Color change mechanisms indicate state change.
Fruits and berries are masters of focus-grouped advertising---they are specifically colored to attract the birds, mammals, and even fi sh that will best spread their seed. The ripening process is highly orchestrated as well, with berries staying a...
38. Head structures absorb shock: golden-fronted woodpecker
"The woodpecker’s beak...is a specialized chisel effective in cutting into a tree; unlike a human-made chisel, the beak is self-sharpening...; the beak, made of elastic material, is relatively large compared to the body. This endoskeletal fe...
39. Multiple mechanisms help flies adhere.
"A fly can easily walk on the most slippery surfaces or stand still on a ceiling for hours. Its feet are better equipped to hold on to glass, walls and ceilings than those of a climber. If the retractable claws are not enough, suction pads on its ...
40. Nest lined with protective material: song thrush
"The song-thrush (Turdus philomelos) lines its nest cup with rotting wood fibres, which creates a kind of a pulp that hardens into a cardboard-like material." (Pallasmaa 1995:20)
