The XR Week Peek: Leaks and rumors about Apple headset intensify, VRChat to launch Creator Economy, and more!

Posted by in category: economics

It’s been a strange week. On the technological side, it has been exciting. Since there is the possibility that Apple announces its headset soon, all the companies are rushing to announce what they have in the pipeline before the big day. This means that these days we are going to have a lot of announcements. This and the next editions of the newsletter are going to be full of cool pieces of news.

On the work side, it has been busy, very busy. I’m also working on a cool tech prototype and I will share it with you very soon in the next few days on this blog. Be sure not to miss it! Next week I’ll also be at AWE. So the next 2–3 weeks are going to be crazy for me, so sorry if I will make the comments on the newsletter a bit shorter than usual.

AI Reconstructs ‘High-Quality’ Video Directly from Brain Readings in Study

Posted by in category: robotics/AI

Researchers have used generative AI to reconstruct “high-quality” video from brain activity, a new study reports.

Researchers Jiaxin Qing, Zijiao Chen, and Juan Helen Zhou from the National University of Singapore and The Chinese University of Hong Kong used fMRI data and the text-to-image AI model Stable Diffusion to create a model called MinD-Video that generates video from the brain readings. Their paper describing the work was posted to the arXiv preprint server last week.

Their demonstration on the paper’s corresponding website shows a parallel between videos that were shown to subjects and the AI-generated videos created based on their brain activity. The differences between the two videos are slight and for the most part, contain similar subjects and color palettes.

Stretching metals at the atomic level allows researchers to create important materials for quantum applications

Posted by in categories: chemistry, computing, engineering, nanotechnology, quantum physics

A University of Minnesota Twin Cities-led team has developed a first-of-its-kind, breakthrough method that makes it easier to create high-quality metal oxide thin films out of “stubborn” metals that have historically been difficult to synthesize in an atomically precise manner. This research paves the way for scientists to develop better materials for various next-generation applications including quantum computing, microelectronics, sensors, and energy catalysis.

The researchers’ paper is published in Nature Nanotechnology.

“This is truly remarkable discovery, as it unveils an unparalleled and simple way for navigating material synthesis at the atomic scale by harnessing the power of epitaxial strain,” said Bharat Jalan, senior author on the paper and a professor and Shell Chair in the University of Minnesota Department of Chemical Engineering and Materials Science.

Higgs Boson: Our Passport to the Hidden Valley of New Physics in Next-Gen Particle Accelerators

Posted by in categories: futurism, particle physics

It may be that the famous Higgs boson, co-responsible for the existence of masses of elementary particles, also interacts with the world of the new physics that has been sought for decades. If this were indeed to be the case, the Higgs should decay in a characteristic way, involving exotic particles. At the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow, it has been shown that if such decays do indeed occur, they will be observable in successors to the LHC currently being designed.

When talking about the ‘hidden valley’, our first thoughts are of dragons rather than sound science. However, in high-energy physics, this picturesque name is given to certain models that extend the set of currently known elementary particles. In these so-called Hidden Valley models, the particles of our world as described by the Standard Model belong to the low-energy group, while exotic particles are hidden in the high-energy region. Theoretical considerations suggest then the exotic decay of the famous Higgs boson, something that has not been observed at the LHC accelerator despite many years of searching. However, scientists at the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow argue that Higgs decays into exotic particles should already be perfectly observable in accelerators that are successors to the Large Hadron Collider – if the Hidden Valley models turn out to be consistent with reality.

“In Hidden Valley models we have two groups of particles separated by an energy barrier. The theory is that there could then be exotic massive particles that could cross this barrier under specific circumstances. The particles like Higgs boson or hypothetic Z’ boson would act as communicators between the particles of both worlds. The Higgs boson, one of the most massive particle of the Standard Model, is a very good candidate for such a communicator,” explains Prof. Marcin Kucharczyk (IFJ PAN), lead author of an article in the Journal of High Energy Physics, which presents the latest analyses and simulations concerning the possibility of detecting Higgs boson decays in the future lepton accelerators.

Designing synthetic receptors for precise cell control

Posted by in categories: biological, chemistry, computing, engineering

Biosensors are artificial molecular complexes designed to detect the presence of target chemicals or even biomolecules. Consequently, biosensors have become important in diagnostics and synthetic cell biology. However, typical methods for engineering biosensors focus on optimizing the interactions between static binding surfaces, and current biosensor designs can only recognize structurally well-defined molecules, which can be too rigid for “real-life” biology.

“We developed a novel computational approach for designing protein-peptide ligand binding and applied it to engineer cell-surface chemotactic receptors that reprogrammed cell migration,” says EPFL professor Patrick Barth. “We think that our work could broadly impact the design of protein binding and cell engineering applications.”

The new biosensors developed by Barth’s group can sense flexible compounds and trigger complex cellular responses, which open up new possibilities for biosensor applications. The researchers created a , which is a computer-based system, for designing protein complexes that can change their shape and function dynamically—as opposed to the conventional static approaches. The framework can look at previously unexplored protein sequences to come up with new ways for the protein’s groups to be activated, even in ways that are different to their natural function.

Bridging Quantum Theory and Relativity: Curved Spacetime in a Quantum Simulator

Posted by in categories: particle physics, quantum physics

New techniques can answer questions that were previously inaccessible experimentally — including questions about the relationship between quantum mechanics and relativity.

Scientists at TU Wien and other institutions have developed a “quantum simulator” using ultracold atomic clouds to model quantum particles in curved spacetime, marking a major step toward reconciling quantum theory and the theory of relativity. The model system offers a tool to study gravitational lensing effects in a quantum field, which may lead to new insights in the elusive field of quantum gravity and other areas of physics.

The theory of relativity works well when you want to explain cosmic-scale phenomena — such as the gravitational waves.

The US now has 150 of the TOP500 supercomputers in the world

Posted by in category: supercomputing

China has slipped to number two, but is that intentional?

The US has edged past China when it comes to being home to the world’s fastest supercomputers. The number of machines in the U.S. is now 150, up from 126 last year, while the number of supercomputers from China fell from 162 to 134, Techspot.
