Vincent van Gogh’s ‘The Starry Night’ is not a masterpiece when it comes to flow physics, researchers say

The Dutch master Vincent van Gogh may have painted one of Western history’s most enduring works, but “The Starry Night” is not a masterpiece of flow physics—despite recent attention to its captivating swirls, according to researchers from Virginia Commonwealth University and the University of Washington.

Revolutionizing 3D vision: How miniaturized snapshot polarization imaging is transforming depth sensing

Capturing precise 3D details with a single camera has long been a challenge. Traditional methods often require complex dual-camera setups or specialized lighting conditions that are impractical for real-world applications. However, a groundbreaking approach developed at Nanjing University is set to redefine 3D imaging.

Quantum entanglement reveals strange metals’ unique electron behavior at critical point

Scientists have long sought to unravel the mysteries of strange metals—materials that defy conventional rules of electricity and magnetism. Now, a team of physicists at Rice University has made a breakthrough in this area using a tool from quantum information science. Their study, published recently in Nature Communications, reveals that electrons in strange metals become […]

Quantum imaging method developed for enhanced image clarity

For decades, quantum imaging has promised sharper images and greater light sensitivity than classical methods by exploiting the unique properties of quantum light, such as photon entanglement. But the approaches to do so rely on delicate, specially engineered light sources that are easily overwhelmed by real-world noise, and it is difficult to generate quantum light […]

Commercial fusion power plant now closer to reality

Successfully harnessing the power of fusion energy could lead to cleaner and safer energy for all—and contribute substantially to combating the climate crisis. Towards this goal, Type One Energy has published a comprehensive, self-consistent, and robust physics basis for a practical fusion pilot power plant.

Symmetry between up and down quarks is more broken than expected

In late 2023, Wojciech Brylinski was analyzing data from the NA61/SHINE collaboration at CERN for his thesis when he noticed an unexpected anomaly—a strikingly large imbalance between charged and neutral kaons in argon–scandium collisions. He found that, instead of being produced in roughly equal numbers, charged kaons were produced 18.4% more often than neutral kaons. […]

Efficient light control: Meta-optics replace conventional lenses

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and consist of an array of tiny structures known as meta-atoms. Meta-atoms influence light at a subwavelength scale and thus allow for highly precise control of […]

Physicist revisits the computational limits of life and Schrödinger’s essential question in the era of quantum computing

More than 80 years ago, Erwin Schrödinger, a theoretical physicist steeped in the philosophy of Schopenhauer and the Upanishads, delivered a series of public lectures at Trinity College, Dublin, which eventually came to be published in 1944 under the title “What is Life?”
