ICD/ITKE Research Pavilion 2015-16 : Some of the most splendid manifestations of biomimetic architecture can be seen in examples where the mimicry is not just a superficial replication but is a creation that comes out of holistic understanding of the specimen itself.

"A designer has an idea of how to make drivers take more caution around cyclists: Help them see bikers as people, not obstacles. [...] The jacket uses sensors to tell if a car or bus is approaching, and then starts flashing LED lights. As cars get closer or drive faster, the lights flash more quickly. The design is inspired by animals that use visual signals to keep predators away."
"An international team of scientists led by Newcastle University, UK, and funded by the US Office of Naval Research, have shown for the first time that barnacle larvae release an oily droplet to clear the water from surfaces before sticking down using a phosphoprotein adhesive."
Some bird eggs have visual signatures that help them distinguish they own clutch from impostor cuckoo .
For most honest bird species, brood parasites like the cuckoo are no joke. These sneaky free-loaders comprise about one percent of all bird species. Sniffing out false eggs is serious business for many birds. Brood parasites plant eggs in unsuspecting nests and leave the duped foster parents to care for their chicks—usually to the deadly detriment of the foster parents' own babies.
Now, researchers from Harvard University and the University of Cambridge have discovered one way that bird parents likely keep an eye on their own eggs: with special visual signature. The researchers used the same kind of software that companies rely on for facial recognition and image stitching but applied that technology to hundreds of eggs of eight different parasitized bird species. They call the new program NaturePatternMatch.
The host birds, they found, have previously unrecognized egg "signatures"—essentially, secret visual cues that allow them to recognize their own among the imposters. The more intensely the bird species is targeted by cuckoos, the more complex and sophisticated their egg signatures. Some of the host birds, they found, produce exactly the same egg, whereas some show variation within their own clutch or between females within the same species. All of these methods, the team says, would likely be effective strategies for lessening the likelihood of being duped.
"The ability of Common Cuckoos to mimic the appearance of many of their hosts' eggs has been known for centuries," the researchers say in a statement. "The astonishing finding here is that hosts can fight back against cuckoo mimicry by evolving highly recognizable patterns on their own eggs, just like a bank might insert watermarks on its currency to deter counterfeiters."
It sounds like the beginning of a bad joke: A brain expert, a bat biologist, and an engineer walk into a cafeteria. But that's exactly what happened when a casual meeting of the minds at England's Leeds University led to the ...
Its transparent wings fixed to a delicate wire framework recall the diaphanous, veined wings of an insect. But when the flying machine rises gracefully into the air, the undulations of its conical form resemble nothing so much as ...
"Beating its tiny wings up to 80 times a second a hummingbird will dart from flower to flower, its iridescent plumage dazzling in the tropical sun. But these busy birds are con artists. Their feathers are pigment-free, the colours the product of microscopic structures that refract sunlight like a prism, spraying out its reds, blues and greens."
Cellular functions within living organisms are extremely complex processes and researchers have been using nanopatterned substrates to control and monitor cellular functions in order to design and fabricate nanoscale biotechnological systems. Especially stem cell research has benefitted from nanopatterned surfaces to maintains stem cells' long-term viability and phenotype during experiments. Nevertheless, despite the intense scientific efforts to achieve precise control of stem cell fates with engineered nanopatterned substrates, reliable and cost effective control of stem cell behavior remains a challenge. Most of the tissues and organs in the human body, with their distinct three-dimensional structures, require support – scaffold/substrate, template, and artificial extracellular matrix or niche – for their formation from diverse cells. Researchers have now fabricated biomimetic substrates that are similar to that of the native extracellular matrix (ECM) in the epidermis which assists proliferation, differentiation, and biosynthesis of the keratinocyte (i.e. human outer skin) cells.
