To get around the constraints of quantum physics, researchers have built a new acoustic system to study the way the minuscule atoms of condensed matter talk together. They hope to one day build an acoustic version of a quantum computer.

Scientists investigated whether email interventions informed by behavioral science could help teachers help students learn math.

Mathematicians studied the flow of human crowds and developed a way to predict when pedestrian paths will transition from orderly to entangled. Their findings may help inform the design of public spaces that promote safe and efficient thoroughfares.

A team of researchers has developed a new tool designed to revolutionize hardware troubleshooting, with the help of 3D phone scans.

Researchers developed a scalable interconnect that facilitates all-to-all communication among many quantum processor modules by enabling each to send and receive quantum information on demand in a user-specified direction. They used the interconnect to demonstrate remote entanglement, a type of correlation that is key to creating a powerful, distributed network of quantum processors.

A study found that when people were told to imagine their virtual bodies in pain, their brains resisted the illusion of ownership. Their findings could provide insights into why some people may struggle with feeling connected to their own bodies, particularly in contexts involving depersonalization or negative physical states.

Researchers developed a hybrid AI approach that can generate realistic images with the same or better quality than state-of-the-art diffusion models, but that runs about nine times faster and uses fewer computational resources. The tool uses an autoregressive model to quickly capture the big picture and then a small diffusion model to refine the details of the image.

Advances in the gene-editing technology known as CRISPR-Cas9 over the past 15 years have yielded important new insights into the roles that specific genes play in many diseases. But to date this technology -- which allows scientists to use a 'guide' RNA to modify DNA sequences and evaluate the effects -- is able to target, delete, replace, or modify only single gene sequences with a single guide RNA and has limited ability to assess multiple genetic changes simultaneously. Now, however, scientists have developed a series of sophisticated mouse models using CRISPR ('clustered regularly interspaced short palindromic repeats') technology that allows them to simultaneously assess genetic interactions on a host of immunological responses to multiple diseases, including cancer.

Memristors consume extremely little power and behave similarly to brain cells. Researchers have now introduced novel memristive that offer significant advantages: they are more robust, function across a wider voltage range, and can operate in both analog and digital modes. Their unique properties could help address the problem of 'catastrophic forgetting,' where artificial neural networks abruptly forget previously learned information.

Scientists recently unveiled a first-of-its-kind authentication protocol for wireless, battery-free, ultraminiaturized implants that ensures these devices remain protected while still allowing emergency access.

Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method.

Sensors attached to animals gather valuable data to track and mitigate the human influence on marine life. The review paper emphasizes the importance of integrating data from various sources and advocates for an 'Internet of Animals' based on open access and shared standards.

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, conduct heat. However, things are not as straightforward under extreme conditions such as temperatures close to absolute zero combined with strong magnetic fields, where strange quantum effects begin to dominate. This is particularly true in the realm of quantum materials.

AI-driven software is 96% accurate at diagnosing Parkinson's.

A new AI tool builds sophisticated map of mouse brains.

For adolescents struggling with substance abuse, traditional in-person interventions such as counseling are not always effective, and rural areas often lack access to these services. A researcher is thinking outside the box, aiming to help game designers develop fun, digital games that make ditching bad habits easier by meeting adolescents where they already are: online.

Scientists have recently detailed how automation and machine learning can aid clinicians treating patients with spreading depolarizations, sometimes referred to as 'brain tsunamis.'

Newly published research demonstrates a novel way of generating phonon-polaritons by making electrons collide with crystal lattice structures. The discovery paves the way for cheaper, smaller long-wave infrared light sources and more efficient device cooling.

A leaping robot could have application in search and rescue, construction, even forest monitoring. But how do you design a robot to stick a landing on a branch or pipe? Biologists worked with robot designers to discover how squirrels do it, and used what they learned to design a one-legged robot with the balancing ability and leg biomechanics to correct for over- and undershooting and land successfully on a narrow perch.

Scientists have successfully established the world's longest intercontinental ultra-secure quantum satellite link, spanning 12,900 km. Using the Chinese quantum microsatellite Jinan-1, launched into low Earth orbit, this milestone marks the first-ever quantum satellite communication link established in the Southern Hemisphere.
