Artificial solid fog material creates pleasant laser light

With a porosity of 99.99 %, it consists practically only of air, making it one of the lightest materials in the world: Aerobornitride is the name of the material developed by an international research team led by Kiel University. The scientists assume that they have thereby created a central basis for bringing laser light into a broad application range. Based on a boron-nitrogen compound, they developed a special three-dimensional nanostructure that scatters light very strongly and hardly absorbs it. Irradiated with a laser, the material emits uniform lighting, which, depending on the type of laser, is much more efficient and powerful than LED light. Thus, lamps for car headlights, projectors or room lighting with laser light could become smaller and brighter in the future. The research team presents their results in the current issue of the renowned journal Nature Communications, which was published today.

More light in the smallest space

In research and industry, has long been considered the “next generation” of light sources that could even exceed the efficiency of LEDs (light-emitting diode). “For very bright or a lot of light, you need a large number of LEDs and thus space. But the same amount of light could also be obtained with a single diode that is one-thousandth smaller,” Dr. Fabian Schütt emphasizes the potential. The materials scientist from the working group “Functional Nanomaterials” at Kiel University is the first author of the study, which involves other researchers from Germany, England, Italy, Denmark and South Korea.

A Surprising Breakthrough Will Allow Tiny Implants to Fix – and Even Upgrade – Your Body

Known as an ion-gated transistor (IGT), the new class of technology effectively melds electronics with molecules of human skin.

But wait, you no longer need any of those, since you recently got one of the new biomed implants — a device that integrates seamlessly with body tissues, because of a watershed breakthrough that happened in the early 2020s. It’s an improved biological transistor driven by electrically charged particles that move in and out of your own cells. Like insulin pumps and cardiac pacemakers, the medical implants of the future will go where they are needed, on or inside the body.

Scientists at @Columbia built a new ion-driven transistor that can safely interact with human skin. What does this mean for the future of #medical #bioelectronics? Find out via @PhysicsWorld: https://bddy.me/2YsvJ0g #wearabletech #healthIT pic.twitter.com/qj3LX3Dqfx

Intel to Release Neuromorphic-Computing System

Intel Corp. is releasing an experimental research system for neuromorphic computing, a cutting-edge method that simulates the way human brains work to perform computations faster, using significantly less energy.

The system, called Pohoiki Springs, will be made available this month over the cloud to members of the Intel Neuromorphic Research Community, which includes academic researchers, government labs and about a dozen companies such as Accenture PLC and Airbus SE.

Others, including International Business Machines Corp., are also researching the technique.

The imitation game: Scientists describe and emulate new quantum state of entangled photons

:oooo.

A research team from ITMO University, with the help of colleagues from MIPT (Russia) and Politecnico di Torino (Italy), has predicted a novel type of topological quantum state of two photons. Scientists have also applied a new, affordable experimental method for testing this prediction. The method relies on an analogy: Instead of expensive experiments with quantum systems of two or more entangled photons, the researchers have used resonant electric circuits of higher dimensionality described by similar equations. The obtained results can be useful for the engineering of optical chips and quantum computers without the need for expensive experiments. The research was published in Nature Communications.

Light plays a key role in modern information technologies: With its help, information is transmitted over large distances via optical fibers. In the future, scientists anticipate the invention of optical chips and computers that process information with the help of photons—light quanta—instead of electrons, as it is done today. This will decrease energy consumption, while also increasing the capabilities of computers. However, to turn these predictions into reality, fundamental and applied research of light behavior at the micro- and nanoscale is needed.

In the new study, the researchers have theoretically predicted the formation of a new quantum state of photons: Two photons propagating in the array of quantum microresonators (qubits) can form a bound pair and settle down on the edge of the array. A proper experiment demands special nanostructures, as well as special devices to create such quantum state of photons and detect it. Currently, such capabilities are available only to very few research teams worldwide.

This Library In Minecraft Was Built By 24 People To Fight Censorship Across The World

Love this convergence of metaverse and fighting censorship with style. Wonder when Microsoft will start getting pressure about this or other kinds of content.

Most of us live in countries where freedom of speech is considered a fundamental human right and it would be hard to imagine living in a different state than that. However, not all of us are blessed with this sometimes overlooked right as there are a number of countries in this world where governments actively censor their citizens, especially those whose profession is to report facts. Journalists.

In a number of places around the world, journalists are banned, jailed, exiled, and even killed for their words. In order to make their message heard and reach the places where they’re banned, Reporters Without Borders (RSF) opened a special type of library that could reach millions. They built it in Minecraft.

The creators reason their choice by explaining the library’s accessibility: ” Reporters Without Borders (RSF) used this backdoor to build ” The Uncensored Library”: a library that is now accessible on an open server for Minecraft players around the globe. The library is filled with books containing articles that were censored in their country of origin. These articles are now available again within Minecraft—hidden from government surveillance technology inside a computer game. The books can be read by everyone on the server, but their content cannot be changed. The library is growing, with more and more books being added to overcome censorship.”

A new theory of magnetar formation

Magnetars are neutron stars endowed with the strongest magnetic fields observed in the universe, but their origin remains controversial. In a study published in Science Advances, a team of scientists from CEA, Saclay, the Max Planck Institute for Astrophysics (MPA), and the Institut de Physique du Globe de Paris developed a new and unprecedentedly detailed computer model that can explain the genesis of these gigantic fields through the amplification of pre-existing weak fields when rapidly rotating neutron stars are born in collapsing massive stars. The work opens new avenues to understand the most powerful and most luminous explosions of such stars.

Magnetars: what are they?

Neutron stars are compact objects containing one to two within a radius of about 12 kilometers. Among them, magnetars are characterized by eruptive emission of X-rays and gamma rays. The energy associated with these bursts of intense radiation is probably related to ultra–. Magnetars should thus spin down faster than other neutron stars due to enhanced magnetic braking, and measurements of their rotation period evolution have confirmed this scenario. We thus infer that magnetars have a dipole magnetic field of the order of 1015 Gauss (G), i.e., up to 1000 times stronger than typical neutron stars! While the existence of these tremendous magnetic fields is now well established, their origin remains controversial.

Windows 10’s built-in Linux kernel will be available to everyone soon

You won’t have to be a tester to try Windows 10’s new, built-in Linux kernel in the near future. Microsoft has confirmed that Windows Subsystem for Linux 2 will be widely available when Windows 10 version 2004 arrives. You’ll have to install it manually for a “few months” until an update adds automatic installs and updates, but that’s a small price to pay if you want Linux and Windows to coexist in peace and harmony. It’ll be easier to set up, at least — the kernel will now be delivered through Windows Update instead of forcing you to install an entire Windows image.
