alternative_right writes: 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 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 published in the journal Nature Communications.

An anonymous reader quotes a report from the Guardian: A ban on mobile phones in schools in England is to be introduced by the government to ensure that "critical safeguarding legislation" is passed. The government will table an amendment to the children's wellbeing and schools bill in the House of Lords after the bill was held up by peers on opposition benches. It will make existing guidance on mobile phone bans in schools statutory, a move that ministers have resisted until now. The government had consistently argued that the vast majority of schools had already banned mobile phones, and that there was no need to add a legal requirement. They finally capitulated, however, describing it as "a pragmatic measure" to get the bill through. [...] The bill is regarded by many as the biggest piece of child protection legislation in decades and includes proposals for a compulsory register for children who are not in school, a crackdown on profiteering in children's social care, and a "single unique identifier" to help agencies track a child's welfare.

The Associated Press looks at the small-but-growing "rebellion" against attention-hogging devices, citing "a growing body of literature calling for people to move away from screens and pay attention to life." D. Graham Burnett is a historian of science at Princeton University and one of the authors of " Attensity! A Manifesto of the Attention Liberation Movement," making him a pillar of the growing backlash against the corporate harvesting of human attention. Along with MS NOW host Chris Hayes' bestselling " The Sirens' Call: How Attention Became the World's Most Endangered Resource," his work is part of a growing body of literature calling for people to move away from screens and pay attention to life. Burnett says the "attention liberation movement" is about throwing off the yoke of time-sucking apps. People "need to rewild their attention. Their attention is the fullness of their relationship to the world".... There are several dozen "attention activism" groups across the United States and Canada, and the movement has also cropped up in Spain, Italy, Croatia, France and England. Burnett said he expects it to spread further. Some examples cited in the article: "More than a dozen millennials gathered in a brownstone apartment in Brooklyn and placed their phones in a metal colander before two hours of reading, drawing and conversation." A few miles away "Nearly 20 people in their 30s stared at their cellphones for a few minutes. Then they set them down and looked at their bared palms for a while. Then those of their neighbors." Thanks to long-time Slashdot reader destinyland for sharing the article.
