Are sound waves a better way to move data?

Researchers from the University of Leeds and Sheffield University have created a way to move data through magnetic nanowires by using surface acoustic waves as the motivating force. Being developed for use in so-called racetrack solid-state memory, the researchers claim that using sound waves for data transfer should markedly increase computer processing speeds while vastly reducing power consumption.

Material that could revolutionize memory storage is magnetic, but not as we know it

Using a type of magnetic insulator material that normally doesn’t conduct electricity, scientists working at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory have shown that electric currents can still be made to flow along the borders of the grains within the material. This latest research not only validates a long-held belief that magnetic insulators could be used to conduct electricity, but offers a more tantalizing possibility of creating highly-efficient magnetic memory devices.

All-optical permanent on-chip memory paves the way for faster, more efficient computers

A new non-volatile optical memory has been created by researchers working at the Karlsruhe Institute of Technology (KIT) and the universities of Münster, Oxford, and Exeter. Utilizing innovative phase-change materials to store information, the new device promises to significantly improve processing speeds by effectively eliminating the existing bottleneck of having to convert optical signals into electrical signals for storage and then back again for transmission.

"Autobiographical memory" lets robots act as knowledge go-betweens for ISS crews

Anyone who's had to take on job responsibilities from someone who left the company months ago will appreciate this robotic system designed with the International Space Station (ISS) in mind. With the design challenge of retaining important experiential information between rotating crews of astronauts, French researchers used the popular Nao robot to form an "autobiographical memory" of human interactions and pass on the know-how to new crew members.

New therapy to help addicts put memories of meth use behind them

Even after a lengthy period of abstinence, putting lingering memories of methamphetamine use to rest is a difficult and often impossible task for former users. Therapies are available to help people stay clean, but for many the lure remains irresistible with incredibly high relapse rates of more than 90 percent, according to the National Institute on Drug Abuse. But a research team is hoping to help addicts stay away from the devastating drug for good by developing a way to safely erase drug-associated memories.

Intel and Micron announce memory breakthrough

If being a processor chip was a human job, it would be one of the most boring. That's because modern processors spend a lot of their time doing not much of anything, as they wait for the slower memory chips to catch up with them. But that may change if Intel Corporation and Micron Technology's new 3D XPoint (3D Crosspoint) technology pans out. Described by the makers as a "major breakthrough in memory process technology," it's the first new class of non-volatile memory to be released since 1989 and is reportedly 1,000 times faster than NAND flash memory.
