'Chaogates' hold promise for the semiconductor industry

  • PDF
TechAndComputer (Nov. 17, 2010) — In a move that holds great significance for the semiconductor industry, a team of researchers has created an alternative to conventional logic gates, demonstrated them in silicon, and dubbed them "chaogates." The researchers present their findings in Chaos, a journal published by the American Institute of Physics.

Simply put, they used chaotic patterns to encode and manipulate inputs to produce a desired output....

'Racetrack' magnetic memory could make computer memory 100,000 times faster

  • PDF
TechAndComputer (Nov. 15, 2010) — Imagine a computer equipped with shock-proof memory that's 100,000 times faster and consumes less power than current hard disks. EPFL Professor Mathias Kläui is working on a new kind of "Racetrack" memory, a high-volume, ultra-rapid non-volatile read-write magnetic memory that may soon make such a device possible.

Annoyed by how long it took his computer to boot up, Kläui began to think about an alternative. Hard...

Tiny brained bees solve a complex mathematical problem

  • PDF
TechAndComputer (Oct. 25, 2010) — Bumblebees can find the solution to a complex mathematical problem which keeps computers busy for days.

Scientists at Royal Holloway, University of London and Queen Mary, University of London have discovered that bees learn to fly the shortest possible route between flowers even if they discover the flowers in a different order. Bees are effectively solving the 'Travelling Salesman Problem', and these are the...
