#A Team Of MIT Bartender Robots Serves Beer More Efficiently Using robots, a team at MIT Computer science and Artificial intelligence Laboratory has solved an ancient problem:
Recently, researchers have looked to DNA as a method to store large amounts of digital information that are saved currently on hard drives.
Our hard drives may seem pretty stable for now, but because of what they're made of,
our hard drives can store up to five terabytes of data, encoded with the zeros and ones of binary code.

the idea of a personal DNA hard drive within the body may also be possible. According to Dr. Narayan, it already happening at the microbial level. everal years ago researchers built the first self-replicating bacterial cell
There also another reason why this personalized biological hard drive may not be the best option. We do not yet have the technology to read it.
There is little doubt the future of the DNA hard drive is bright. Yet while the biological aspects may be suited perfectly for a variety of applications
For Dr. Narayan, the answer to the future of the DNA hard drive is clear. NA as a medium for archival storage may have place in digital storage.

#Fiber-like light emitting diodes for wearable displays A research team at Korea Advanced Institute of Science
and Technology (KAIST) has developed fiber-like light emitting diodes, applicable to wearable displays. Professor Kyung-Cheol Choi and his research team from the School of Electrical engineering at KAIST have developed fiber-like light emitting diodes,
which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials.
Traditional wearable displays were manufactured on a hard substrate, which is attached later to the surface of clothes.
Such technique has posed limitations in applying it for wearable displays because inflexible displays were not adequate in practice,
and the characteristics of fabric were ignored. For a solution, the research team discarded the tradition of creating light emitting displays on a plane board.
Instead, they focused on fibers, a component of fabrics, and developed a fiber-like light emitting diode that has the characteristics of both fabrics and displays.
The essence of this technology, the dip coating process, is to immerse and extract a three dimensional (3-D) board that looks like a thread in a solution.
The researchers said that this technology would accelerate the commercialization of fiber based wearable displays
"Our research will become a core technology in developing light emitting diodes on fibers, which are fundamental elements of fabrics.
