> A new technology has been proposed that could fundamentally solve the issue of smartphones overheating during high-spec gaming or extended video streaming. Researchers at KAIST have discovered the principle of processing signals [2]using the minute vibrations of magnets (spin waves) instead of electrons . This method significantly reduces heat generation and power consumption while enabling instantaneous frequency switching within the several GHz range. This breakthrough is expected to pave the way for smart devices with less heat and longer battery life, as well as ultra-low-power, high-speed computing.
Professor Kab-Jin Kim from the Department of Physics said: "This study is a case that proves we can implement and control the nonlinear dynamics of magnons -- the principle of information processing using magnetic vibrations -- in actual nano-devices, which had previously only been proposed in theory. It will serve as an important foundation for the development of a new information processing paradigm using spin waves instead of electrons."
The findings have been [3]published in the journal Nature Communications .

until they get the magnetic memristors.

The blurb is certainly plenty full of gibberish.
Throw out your chargers (Score:2)
Just as all phones are standardizing on using electromagnetic fields for charging. I can already picture it: a dongle you put in your car's wireless charging compartment, with a wire running out plugged into your phone that's bouncing around your floor.
Another stupid headline (Score:3)
Yes, this may eventually go into production. No, it will not be the "next" thing or the one after it. While very few of these discoveries make it, those that do take 20 years, 30 years or longer to get there.
May be big for AI (Score:2)
The computer architecture we use for AI given what it does and how much of it is probabilistic is really dumb and wasteful, spintronics is one candidate to speed it up if a few problems are solved.

Any performance uplift of RAM applies equally to any use of RAM. AI isn't special here.
Here we go again (Score:2)
Not looking towards worrying about magnets coming into proximity of computers again.
