Researchers at The University of Manchester have discovered record-high magnetoresistance in graphene.

Graphene is an allotrope of carbon in the form of a single layer of atoms in a two-dimensional hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes of carbon, including graphite, charcoal, carbon nanotubes, and fullerenes. In proportion to its thickness, it is about 100 times stronger than the strongest steel.

DGIST Professor Yoonkyu Lee’s research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible electrode materials and consequently enabling its mass production. The results were published in the February 23 issue of Nano Energy.

This technology is applicable to various 2D materials, and its applicability can be extended to the synthesis of various metal-2D material nanowires.

The research team used copper-graphene nanowires to implement high-performance transparent-flexible electronic devices such as transparent-flexible electrodes, transparent supercapacitors and transparent heaters and to thereby demonstrate the commercial viability of this material.

Silver, gold and copper nanowires are leading contenders for next-generation nanoscale devices, however greater understanding of how they work and improved production methods are needed before they can be widely used, explains a recent review in the journal Science and Technology of Advanced Materials.

“Metal nanowires are used for numerous applications, but our understanding of their mechanical properties remains elusive,” says Nurul Akmal Che Lah, engineer at Universiti Malaysia Pahang.

Lah and colleague Sonia Trigueros at the University of Oxford reviewed methods for synthesising and analysing silver, gold and copper nanowires for molecular-based electronics.

This film by Ken Gumbs tackles the issue of pending greater-than-human artificial intelligence and the possible ramifications. Different individuals with different backgrounds are interviewed on the subject, including a theologian, a philosopher, a brain builder and a cyborg. A wide spectrum of topics are discussed, including trans-humanism, mind-machine mergers, uploading, and artificial super-intelligence.

An older article but something the world is facing just like in certain sci-fi movies.

The reference publication of the movement in the 80s, the Earth First journal, featured a column called Ask Ned Ludd, in reference to the mythical character that gave name to the luddites. Jones thinks that neo-luddites are in fact misreading the original luddites, but he believes that understanding the difference between the old and modern ones tells us a lot about the ideology of the latter.

“Luddites were not anti-technology: they were skilled craftsmen, involved in a labour movement aimed at keeping their machines and their jobs,” he says. “That’s very different from the neo-luddites ideas of relinquishing civilisation and [of] nature as the supreme good.” Jones thinks neo-luddism is fed rather by “the idea of technology as a disembodied, transcendent, terrifying force outside the human”, which emerged in the mid 20th century, with the bomb and the rise of large-scale computing.

It’s available on phones and now watches? That’s actually nice though I hope they make it battery efficient. The Pixel watch for example already has issues with battery life. I’m the future will there be a small AI server in our bodies in microchips or a network of nanobots?

ChatGPT is all the rage these days, but did you know you can get it on your watch? Here’s how to install it on a Galaxy Watch, Pixel Watch, and other Wear OS watches.

The nanoscale electronic parts in devices like smartphones are solid, static objects that once designed and built cannot transform into anything else. But University of California, Irvine physicists have reported the discovery of nanoscale devices that can transform into many different shapes and sizes even though they exist in solid states.

It’s a finding that could fundamentally change the nature of electronic devices, as well as the way scientists research atomic-scale quantum materials. The study is published in Science Advances.

“What we discovered is that for a particular set of materials, you can make nanoscale electronic devices that aren’t stuck together,” said Javier Sanchez-Yamagishi, an assistant professor of physics & astronomy whose lab performed the new research. “The parts can move, and so that allows us to modify the size and shape of a device after it’s been made.”

This new “nano-excitonic transistor” could revolutionize data processing, especially in the age of AI.
