Researchers have developed a technique called “atomic spray painting” using molecular beam epitaxy to strain-tune potassium niobate, enhancing its ferroelectric properties.
This method allows precise manipulation of material properties, with potential applications in green technologies, quantum computing, and space exploration.
Material Strain Tuning
Dr. Ariel Zeleznikow-Johnston hopes to pick up the movement where Jones left off, albeit with the significant twist that his version does not require freezing. A research fellow at Melbourne’s Monash University, Zeleznikow-Johnston wrote the new book, “The Future Loves You: How and Why We Should Abolish Death,” which makes the case that cryopreservation is possible and should be more widely available. Rejecting the popular notion that death endows life with meaning as “palliative philosophy,” Zeleznikow-Johnston’s book instead argues a human’s connectome — a high-resolution map of all their brain connections — could be theoretically recorded perfectly before they die.
Once that happens, that same internal brain activity could be recreated through high-powered computers, while a new brain is grown in a vat via stem cells or some combination of the two. As such, Zeleznikow-Johnston is proposing a spiritual descendant to the cryonics movement (which he dismisses as “unscientific” and “unsubstantiated”), one where the focus is not on preserving tissues but on the “data,” so to speak, of our distinct connectomes.
“We have very strong evidence that the static structure of the neurons is enough to hold onto someone’s memories and personality.”
A new technology that can generate electricity from vibrations or even small body movements means you could charge your laptop by typing or power your smartphone’s battery on your morning run.
Researchers at the University of Waterloo have developed a tiny, wearable generator in response to the urgent need for sustainable, clean energy. It is also scalable for larger machines. Their paper, “Breaking Dielectric Dilemma: Polymer Functionalized Perovskite Piezocomposite with Large Current Density Output,” is published in the November edition of Nature Communications.
“This is a real game changer,” said Dr. Asif Khan, the project’s lead researcher and a postdoctoral fellow in the Department of Electrical and Computer Engineering at Waterloo. “We have made the first device of its kind that can power electronics at low cost and with unprecedented efficiency.”
Researchers at MIT have developed a design framework for controlling ultrasound wave propagation in microscale acoustic metamaterials, focusing on the precise positioning of microscale spheres within a lattice.
This approach enables tunable wave velocities and responses, and is applicable in fields like ultrasound imaging and mechanical computing.
Acoustic Metamaterials
In the future we can envision FASQ* machines, Fault-Tolerant Application-Scale Quantum computers that can run a wide variety of useful applications, but that is still a rather distant goal. What term captures the path along the road from NISQ to FASQ? Various terms retaining the ISQ format of NISQ have been proposed[here, here, here], but I would prefer to leave ISQ behind as we move forward, so I’ll speak instead of a megaquop or gigaquop machine and so on meaning one capable of executing a million or a billion quantum operations, but with the understanding that mega means not precisely a million but somewhere in the vicinity of a million.
Naively, a megaquop machine would have an error rate per logical gate of order 10^{-6}, which we don’t expect to achieve anytime soon without using error correction and fault-tolerant operation. Or maybe the logical error rate could be somewhat larger, as we expect to be able to boost the simulable circuit volume using various error mitigation techniques in the megaquop era just as we do in the NISQ era. Importantly, the megaquop machine would be capable of achieving some tasks beyond the reach of classical, NISQ, or analog quantum devices, for example by executing circuits with of order 100 logical qubits and circuit depth of order 10,000.

A new quantum processor design features a modular router that allows enhanced qubit connectivity, breaking away from traditional 2D grid constraints.
This approach aims for scalable, fault-tolerant quantum computing that could transform industries by solving problems beyond the reach of classical computers.
Quantum Processor Innovation
With brains that process information almost like a computer, the sea creatures already use tools and can be social. But they need to make a few changes before they can take over the world.
Interim Intel co-CEO Michelle Johnston Holthaus announced that the first engineering samples of hardware manufactured with the company’s 18A semiconductor node have been delivered to customers. Her comments aim to reassure industry observers that Intel’s foundry business remains on track to compete with TSMC’s and Samsung’s 3nm and 2nm nodes starting next year.
At the Barclays Annual Global Technology Conference, Holthaus and co-CEO David Zinsner discussed Intel’s upcoming Panther Lake processors, which will debut the 18A process node upon their expected launch in the second half of 2025. Holthaus revealed that eight foundry customers have powered on ES0 (likely “Engineering Sample 0”) chips built on the 18A node, signaling significant progress compared to six months ago.
Intel released version 1.0 of the 18A process design kit in July, enabling customers to begin developing chips based on the node. In August, the company confirmed that internal samples of Panther Lake and Clearwater Forest processors, built on the 18A node, successfully powered on and booted Windows with satisfactory performance. The statements made at the Barclays event mark the first confirmation of 18A usage outside of Intel.

What is time? Is it just a ticking clock, or is it something more profound?
In this thought-provoking episode of Into the Impossible, Stephen Wolfram challenges everything we know about time, offering a revolutionary computational perspective that could forever change how we understand the universe.
Stephen Wolfram is a computer scientist, physicist, and businessman. He is the founder and CEO of Wolfram Research and the creator of Mathematica, Wolfram Alpha, and Wolfram Language. Over the course of 4 decades, he has pioneered the development & application of computational thinking. He has been responsible for many discoveries, inventions & innovations in science, technology, and business.
He argues that time is the inevitable progress of computation in the universe, where simple rules can lead to complex behaviors. This concept, termed computational irreducibility, implies that time has a rigid structure and that our perception of it is limited by our computational capabilities. Wolfram also explores the relationship between time, space, and gravity, suggesting that dark matter might be a feature of the structure of space.
