The National Institute of Standards and Technology’s new cesium fountain clock is one of the most precise atomic clocks ever created.
Every week quantum computing hits a new milestone: more qubits, fewer errors, better readout of results. But will these breakthroughs help solve the advanced computational problems facing energy, like how to model energy storage catalysts or ensure power grid reliability? That is what scientists at the National Renewable Energy Laboratory (NREL) want to know.
Working with local quantum companies, an NREL team is developing benchmarks for quantum computers on the problems that are important to energy science. The pursuit of benchmarks will allow NREL and industry to prioritize practical utility for the next generation of quantum software and hardware.

The first nonverbal Neuralink patient to receive the chip implant is offering a glimpse into how he uses the technology — editing and narrating a YouTube video using signals from his brain.
Brad Smith is the third person in the world to get a brain chip implant with Elon Musk’s Neuralink, and the first person with ALS to do so.
Amyotrophic lateral sclerosis, also known as Lou Gehrig’s disease, is a progressive neurodegenerative disorder that primarily affects motor neurons — the nerve cells in the brain and spinal cord responsible for controlling voluntary muscle movement. Over time, patients lose voluntary control of muscle movements, affecting their ability to speak, eat, move, and breathe independently.
A Korean research team has developed a new proton exchange membrane (PEM) that significantly enhances the performance of electrochemical hydrogen storage systems. The work was published as a cover article in the Journal of Materials Chemistry A.
Dr. Soonyong So of the Korea Research Institute of Chemical Technology (KRICT) and Professor Sang-Young Lee of Yonsei University have developed a next-generation PEM for LOHC-based electrochemical hydrogen storage using a hydrocarbon-based polymer called SPAES (sulfonated poly(arylene ether sulfone)).
This SPAES membrane reduces toluene permeability by over 60% compared to the commercially available perfluorinated PEM Nafion and improves the Faradaic efficiency of hydrogenation to 72.8%.
Aluminum alloys are widely used in transportation applications because of their high strength-to-weight ratio, as well as their affordability. However, challenges arise when using them in extremely high-strength and high-temperature applications, particularly in components such as pistons of combustion engines, fan blades of jet engines, and vacuum pumps.
At elevated temperatures, few aluminum alloys can block dislocation movements effectively, which controls the strength. Moreover, few of the designs have considered costs and sustainability metrics in the design, which are essential for high-demand industries. Titanium alloys, such as Ti-64, that are often used in fan blades, are not only heavier and not machinable, but also nearly twice as expensive.
Additive manufacturing (AM) is rapidly evolving and providing new pathways for designing innovative alloys. A recent study by Carnegie Mellon University and the Massachusetts Institute of Technology (MIT) researchers has utilized computational simulations and optimization techniques to identify a new aluminum alloy system that balances strength and cost.
It’s spring, the birds are migrating and bird flu (H5N1) is rapidly evolving into the possibility of a human pandemic. Researchers from the University of Maryland School of Public Health have published a comprehensive review documenting research on bird flu in cats and calling for urgent surveillance of cats to help avoid human-to-human transmission.
The work is published in the journal Open Forum Infectious Diseases.
“The virus has evolved, and the way that it jumps between species—from birds to cats, and now between cows and cats, cats and humans—is very concerning. As summer approaches, we are anticipating cases on farms and in the wild to rise again,” says lead and senior author Dr. Kristen Coleman, assistant professor in UMD School of Public Health’s Department of Global, Environmental and Occupational Health and affiliate professor in UMD’s Department of Veterinary Medicine.
Wouldn’t it be great if music creators had someone to brainstorm with, help them when they’re stuck, and explore different musical directions together? Researchers at KAIST and Carnegie Mellon University (CMU) have developed AI technology similar to a fellow songwriter who helps create music.
The work is published in Proceedings of the 2025 CHI Conference on Human Factors in Computing Systems.
The system developed by Professor Sung-Ju Lee’s research team, Amuse, is an AI-based system that converts various forms of inspiration such as text, images, and audio into harmonic structures (chord progressions) to support composition.
A research team led by Professor Yong-Young Noh and Dr. Youjin Reo from the Department of Chemical Engineering at POSTECH (Pohang University of Science and Technology) has developed a technology poised to transform next-generation displays and electronic devices.
The project was a collaborative effort with Professors Ao Liu and Huihui Zhu from the University of Electronic Science and Technology of China (UESTC), and the findings were published in Nature Electronics.
Every time we stream videos or play games on our smartphones, thousands of transistors operate tirelessly behind the scenes. These microscopic components function like traffic signals, regulating electric currents to display images and ensure smooth app operation.
Feelings and experiences vary widely. For example, I run my fingers over sandpaper, smell a skunk, feel a sharp pain in my finger, seem to see bright purple, become extremely angry. In each of these cases, I am the subject of a mental state with a very distinctive subjective character. There is something it is like for me to undergo each state, some phenomenology that it has. Philosophers often use the term (singular ‘quale’) to refer to the introspectively accessible, phenomenal aspects of our mental lives. In this broad sense of the term, it is difficult to deny that there are Disagreement typically centers on which mental states have, whether are intrinsic qualities of their bearers, and how relate to the physical world both inside and outside the head. The status of is hotly debated in philosophy largely because it is central to a proper understanding of the nature of consciousness. are at the very heart of the mind-body problem.
The entry that follows is divided into ten sections. The first distinguishes various uses of the term The second addresses the question of which mental states have The third section brings out some of the main arguments for the view that are irreducible and non-physical. The remaining sections focus on functionalism and, the explanatory gap, and introspection, representational theories of, as intrinsic, nonrepresentational properties, relational theories of and finally the issue of and simple minds.
