A study suggests that a computer-generated breathing coach could be as effective as sessions with a human trainer.

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate.

AI agents trained in simulations that differ from the environments where they are deployed sometimes perform better than agents trained and deployed in the same environment, research shows.

Many materials store information about what has happened to them in a sort of material memory, like wrinkles on a once crumpled piece of paper. Now, a team of physicists has uncovered how, under specific conditions, some materials seemingly violate underlying mathematics to store memories about the sequence of previous deformations.

This novel finding regarding the nonreciprocal diffraction of acoustic waves could open doors for next-generation communication devices.

The universe is getting more disordered, entropy is growing -- this is the second law of thermodynamics. But according to quantum theory, entropy should actually stay the same. Scientists took a closer look and resolved this apparent contradiction.

The narrow, deep holes required for one type of flash memory are made twice as fast with the right recipe, which includes a plasma made from hydrogen fluoride.

In a groundbreaking achievement for quantum technologies, researchers have created a functional quantum register using the atoms inside a semiconductor quantum dot.

Researchers were able to demonstrate for the first time that non-covalent bonds between spin centers are also capable of producing quartet states through spin mixing. Supramolecular chemistry is thus a valuable tool for the research, development and scaling of new materials for quantum technologies.

Can a computer learn a language the way a child does? A recent study sheds new light on this question. The researchers advocate for a fundamental revision of how artificial intelligence acquires and processes language.

A new one-minute video game is able to accurately and efficiently identify children with autism from those who have ADHD or are neurotypical.

A new study finds that prompts do a good job of getting drivers to engage with their environment and take over control of the vehicle when necessary while using partially automated driving systems -- with one exception. If drivers are deeply distracted, these system-generated prompts have little or no effect.

Researchers propose a novel system that uses standing surface acoustic waves to separate circulating tumor cells from red blood cells with unprecedented precision and efficiency. The platform integrates advanced computational modeling, experimental analysis, and artificial intelligence algorithms to analyze complex acoustofluidic phenomena. The researchers included an innovative use of dualized pressure acoustic fields and strategically located them at critical channel geometry positions on a lithium niobate substrate. By means of acoustic pressure applied within the microchannel, the system design provides for the generation of reliable datasets.

Artificial Intelligence (AI) has the potential to transform aging research and help people live healthier, longer lives.

In the same way that terrestrial life evolved from ocean swimmers to land walkers, soft robots are progressing, too, thanks to recent research in battery development and design.

The world of quantum physics is experiencing a second revolution, which will drive an exponential leap in the progress of computing, the internet, telecommunications, cybersecurity and biomedicine. Quantum technologies are attracting more and more students who want to learn about concepts from the subatomic world -- such as quantum entanglement or quantum superposition -- to explore the innovative potential of quantum science. In fact, understanding the non-intuitive nature of quantum technology concepts and recognizing their relevance to technological progress is one of the challenges of 2025, declared the International Year of Quantum Science and Technology by UNESCO.

A research team has introduced a new concept for designing ultra-thin absorbers that enables absorbing layers with a record-high bandwidth-to-thickness ratio, potentially several times greater than that of absorbers designed using conventional approaches.

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method and implemented it experimentally for the first time, with which a quantum computer can switch back and forth between two correction codes and thus perform all computing operations protected against errors.

A scientific team looks at the progress and challenges in the research and development of brain implants. New achievements in the field of this technology are seen as a source of hope for many patients with neurological disorders and have been making headlines recently. As neural implants have an effect not only on a physical but also on a psychological level, researchers are calling for particular ethical and scientific care when conducting clinical trials.

Many people struggle to maintain a healthy weight, and choosing the optimal meals for weight loss can be challenging. A research team has developed a weight management program that helps individuals plan meals with the assistance of a web application and support from a registered dietitian. In a new study, they discuss the app's features, development, and implementation.
