Self-Replicating “DNA Computers” Are Set to Change Everything

Posted by in categories: biotech/medical, computing

Scientists now know how to code information into DNA as though it were a hard drive — the problem is, it’s really expensive to do.

Does quantum theory explain consciousness? Take the test to find out

Posted by in categories: computing, neuroscience, quantum physics

A chess problem could help scientists finally unravel whether quantum theory can explain human consciousness.

Oxford professor Sir Roger Penrose created the puzzle to prove the human mind can never be matched by a computer because it exhibits quantum effects.

This means the brain doesn’t follow the rules for the classical properties of matter like a computer.

IBM Has Devised a Way to “Grow” Computer Chips

Posted by in categories: computing, nanotechnology

In Brief

  • Scientists have devised a way, inspired by nature, of coaxing carbon nanotubes to build themselves into structures that could be used to replace silicon chips.
  • The successful implementation of this technology could lead to faster than silicon computer chips along with bendable electronics.

Traditionally, computer microchips are made of the semiconductor silicon. Silicon is turned into wafers where complex circuitry is carved—but there’s a limit to this complexity and to the chips’ processing capacity, and it’s coming soon.

Scientist from IBM are ushering in a revolution of microchip design by seeking to use carbon nanotubes. The researchers theorize that these nanotube chips could use less electricity, and be six to ten times faster than silicon-based ones.

Scientists Want to Build a Super-Fast, Self-Replicating Computer That “Grows as It Computes”

Posted by in categories: computing, information science, quantum physics

Scientists say it’s possible to build a new type of self-replicating computer that replaces silicon chips with processors made from DNA molecules, and it would be faster than any other form of computer ever proposed — even quantum computers.

Called a nondeterministic universal Turing machine (NUTM), it’s predicted that the technology could execute all possible algorithms at once by taking advantage of DNA’s ability to replicate almost perfect copies of itself over billions of years.

The basic idea is that our current electronic computers are based on a finite number of silicon chips, and we’re fast approaching the limit for how many we can actually fit in our machines.

Scientists reveal new super-fast form of computer that ‘grows as it computes’

Posted by in categories: biotech/medical, computing, engineering, quantum physics

Researchers from The University of Manchester have shown it is possible to build a new super-fast form of computer that “grows as it computes”.

Professor Ross D King and his team have demonstrated for the first time the feasibility of engineering a nondeterministic universal Turing machine (NUTM), and their research is to be published in the prestigious Journal of the Royal Society Interface.

The theoretical properties of such a computing machine, including its exponential boost in speed over electronic and quantum computers, have been well understood for many years – but the Manchester breakthrough demonstrates that it is actually possible to physically create a NUTM using DNA molecules.

This super-fast 3D printer is powered by holograms

Posted by in categories: 3D printing, computing, holograms

The advantage of Daqri’s chip, the company says, is that it can create holograms without the need for complex optics. On a silicon wafer, a tiny grid of tunable crystals is used to control the magnitude and time delay, or phase, of reflected light shined at the surface of the chip from a laser. Software adjusts the crystals to create patterns of interference in the light, resulting in a three-dimensional light field.

In experiments, the team has used the chip to create solid objects by projecting holograms into containers of various light-activated monomers. It can currently make small objects, such as a paper clip, in about five seconds—a process that could take a normal 3D printer several minutes.


A startup called Daqri has technology that can print solid objects faster and also powers a new kind of head-up display.

IBM Is Rolling Out the World’s First Universal ‘Quantum Computing’ Service

Posted by in categories: computing, internet, quantum physics

IBM esta anunciando que estão desenvolvendo um sistema universal de “computação qu ntica”

O serviço será chamado IBM Q, e ele dará às pessoas acesso ao seu computador qu ntico de estágio inicial pela internet para usar como desejar — por uma taxa.

O grande elefante na sala é que, por enquanto, o computador qu ntico da IBM só funciona com cinco qubits, então não é muito mais rápido (se houver mais rápido) do que um computador convencional.
