A DNA Computer Just Computed Square Root of 900

DNA strand

Researchers at the University of Rochester created a computer that uses 32 DNA strands to store and process information. It can calculate the square root of square numbers 1, 4, 9, 16, 25 and so on up to 900.

To start, the team encodes a number onto the DNA using a combination of ten building blocks. Each combination represents a different number up to 900, and is attached to a fluorescence marker.

The team then controls hybridisation in such a way that it changes the overall fluorescent signal so that it corresponds to the square root of the original number. The number can then be deduced from the colour.

Augmented Reality is the Mirrorworld

Kevin Kelly writes how augmented reality will become a mirrorworld; That is, an exact replica of the physical world we will interact with.

The mirrorworld—a term first popularized by Yale computer scientist David Gelernter—will reflect not just what something looks like but its context, meaning, and function. We will interact with it, manipulate it, and experience it like we do the real world.

I firmly believe that AR can be as revolutionary as the internet. We just need an AR device that will dominate peoples’ lives to the point where everyone will wear a headset all the time.

Check Out What AT&T Thought the Future Would Look Like in 1961

· · Cool Stuff Found

Check out this fascinating AT&T video from 1961 called Seeing the Digital Future. AT&T has published a lot of archival material to YouTube, and a friend spotted this one over the weekend. There are lots of things I find interesting about it. For one thing, remember that it’s 1961. AT&T wasn’t the AT&T of today, it was Ma Bell. It was the telephone company. It was the tech giant of its day! And while there’s a lot that misses the mark in this video, there are also some things Ma Bell got right, including the importance of computers being able to talk to each other. I also personally enjoy the 1960s special effects—in color, no less!—and wooden acting. It’s a great glimpse back at how things were, while they were trying to figure out how things would someday be.

Meet Alo, A Phone Concept From The Future

Have you ever wondered about a “post-iPhone” future? Well, French designers Jerome Olivet and Philippe Starck have one possible answer. It involves a metal and resin device they call Alo, and it’s meant to be a voice-only smartphone with built-in artificial intelligence.
