Are DNA computer chips a reality?

Computer chips made from DNA may not only replace traditional silicon, but may also be smaller and faster.

Researchers are paving the way for the future of micro-computing, using DNA (the building blocks of life) to build smaller-than-ever computer chips. These chips will be able to amass far superior amounts of circuitry compared to traditional silicon for only a fraction of the size, and their potential speed is unrivaled to silicon.

One of the main advantages of DNA computer chips is that they are vastly cheaper compared to silicon, according to Chris Dwyer, assistant professor of electrical and computer engineering at Duke's Pratt School of Engineering. This will be beneficial in producing supercomputer machines at an economical price.

The most appealing benefit of DNA computer chips would be their superior processing speeds. They would use light instead of electricity to simulate zeros or ones because of a detector that would differentiate between different wavelengths of light emitted by molecules or chromophores on the chip.

Another group, IBM and the California Institute of Technology, have actually built a computer chip utilizing synthesized DNA molecules. Their chip is a different technology that actually uses DNA as a positioner or mini circuit board for the precise assembly of components, thus making it easier to produce smaller chipsets.

Either technology by either group could substantially reduce the manufacturing cost of computer chips and their size while increasing their speed. The accomplishments by IBM and the California Institute of Technology show that this technology is coming, and the future is now.

HP OfficeJet 250 Mobile Printer

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
