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
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.
Major hard drive maker Western Digital has announced that it is acquiring SanDisk, one of the biggest and most familiar names in flash storage, creating a new global memory giant of sorts.
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.
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.
Where and when you form new memories affects where they are stored in the brain's hippocampus, which is the memory center in our brain, researchers at Ohio State University found in a new study. They saw evidence that a particular part of the hippocampus stores memories relative to time over durations of at least a month and space over distances of up to 30 km (18.6 mi).
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.
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.
Music gets so much easier when you instinctively know all the notes. But being able to reliably identify or reproduce a pitch without error is rare. If you're not born with perfect pitch, prior studies suggest, your only hope of getting it is to receive musical training at a critical period in your childhood. New research at the University of Chicago suggests otherwise, however. Perfect pitch might be attainable well into adulthood.
