IBM To Build Next Generation Chips Using DNA

In future DNA wouldn’t just control human evolution but also computing evolution, if IBM succeeds to use DNA in development of next-generation microchips.


IBM scientists are using DNA scaffolding to build tiny circuit boards; this image shows high concentrations of triangular DNA origami binding to wide lines on a lithographically patterned surface; the inset shows individual origami structures at high resolution.

Scientists at IBM Research and the California Institute of Technology announced a scientific advancement that could be a major breakthrough in enabling the semiconductor industry to pack more power and speed into tiny computer chips, while making them more energy efficient and less expensive to manufacture.

Today, the semiconductor industry is faced with the challenges of developing lithographic technology for feature sizes smaller than 22 nm and exploring new classes of transistors that employ carbon nanotubes or silicon nanowires. IBM’s approach of using DNA molecules as scaffolding – where millions of carbon nanotubes could be deposited and self-assembled into precise patterns by sticking to the DNA molecules – may provide a way to reach sub-22 nm lithography

Verizon Wireless Set To Rollout 4G In 2010

Verizon Wireless completed its first successful Long Term Evolution (LTE) Fourth Generation (4G) data call in Boston based on the 3GPP Release 8 standard; the company also announced that it had earlier completed the first LTE 4G data call based on the 3GPP Release 8 standard in Seattle. While Verizon previously disclosed its intentions to test the 4G standard in the two cities, the carrier had not provided details on the trials until now.

The tests involved streaming video, file uploads and downloads, and Web browsing. Interestingly, Verizon also said it placed voice calls using Voice over Internet Protocol (VoIP) technology to enable voice transmissions over the LTE 4G network, though the carrier has said in the past that it plans to keep most voice traffic on its existing CDMA 1x network.
