Philips Research Laboratories engineers have taken inspiration from moth eyes to develop a coating for solar cells that increases their efficiency. Nanostructures, comparable to the tapered structures on the insects' eyes, reduce the amount of light that's reflected off the photovoltaic material. From Physics World:
To maximize the amount of light entering (moths') eyes, to help them see at night, the insects' eyes are covered in tapered nanostructures. This creates an "effective medium" where the refractive index gradually increases as light travels from air through to the insects' optical nerve. The resulting effective index is close to one, which means that very little light is reflected out of the eye.
Inspired by these biostructures, Gomez Rivas and colleagues have mimicked the effect by growing nanowires of different lengths - creating a metamaterial with optical properties that change gradually as a function of distance.
Mian Wei, a Chinese student at the Rhode Island School of Design, has created an experimental series of fake fingertips with randomly generated fingerprints that work with Apple and Android fingerprint authentication schemes, as well as many others.

It’s been nearly a year since I moved from London to Burbank, and in that time, I’ve been slowly iterating through various online tutorials to be better at charcoal grilling, something I had almost no experience with when I got here.
Experienced shutterbugs with DSLR cameras have boatloads of lens options for capturing the moment. Unfortunately, smartphone photographers often get stuck with their one crummy lens, which means limited zoom and focus for their final image.Step up your smartphone’s photographic power with the Acesori 5-Piece Smartphone Camera Lens Kit, now just $9.99 in the Boing Boing Store.Magnetic rings easily […]
Some truths are universal. For one, your phone will always run out of power when you most need it. For another, the charging cords that come packaged with your Apple device will fray, split, and rip faster than Usain Bolt in a game of tag.Instead, pick up a charging cord that anyone would have a tough […]
Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp. And now, we’re giving you the ability to put a few parlor tricks up your sleeve with the Penguin […]
