Through Teslaphoresis, nanotubes can be directed to assemble themselves into wires within this force field, making it possible to build circuits without physical contact.
Scientists from Rice University found a way to conduct electricity without making physical contact between the circuit and the energy source. Using a Tesla coil’s antenna to project a gradient high-voltage forcefield into air, they were able to polarize carbon nanotubes within this Teslaphoretic (TEP) field, which then spring out like webs to assemble themselves into wires.

Engineers have developed a type of camera that doesn’t require any lenses. They’re replacing curved glass with something that does the same job computationally – an ultra-thin optical phased array.
Researchers hope that the findings could turn a wide range of flat surfaces into image collectors.
To capture the perfect selfie or Instagram photo, cameras use lenses. In digital cameras, the lenses are used to focus the light on to a digital sensor. The optical phased array has a group of light receivers that adds a minute delay to the light as it is captured. This allows the camera to switch focus and look in different directions using nothing but electronic trickery.

Jeanne Calment, the French woman who holds the record for the longest verified lifespan, died in 1997 at 122 years old.
Few people, of course, ever become supercentenarians — 110 years old or older — and even fewer hit 115.
