After nearly 100 years, scientists may have detected dark matter

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark matter—holding the galaxies together. Nearly 100 years later, NASA’s Fermi Gamma-ray Space Telescope may have provided direct evidence of dark matter, allowing the invisible matter to […]

Yggdrasil, The Legendary World Tree Of Norse Mythology

In the beginning of the Norse cosmos, there existed an eternal Void, known as Ginnungagap. Out of this nothingness sprang Yggdrasil, a huge Ash tree. Its newly emerging branches held two primordial worlds; Niflheim, a world of ice & frost, and Muspellheim, a realm of molten fire.

When a spring erupted from Nifelheim (known […]

New X-ray method captures 3 image-contrast types in a single shot

University of Houston researchers developed a new X-ray imaging method capable of revealing hidden features in a single shot, a breakthrough that could advance cancer detection, disease monitoring, security screening and material analysis.

Puzzling ultraviolet radiation in the birthplaces of stars

Researchers used the MIRI instrument onboard the James Webb Space Telescope (JWST) to identify the presence of ultraviolet radiation in five young stars in the Ophiuchus region, and to understand its role in the formation of stars. The discovery of UV radiation around these protostars and its significant impact on the surrounding material is a […]

Adaptive method helps light-based quantum processors act more like neural networks

Machine learning models called convolutional neural networks (CNNs) power technologies like image recognition and language translation. A quantum counterpart—known as a quantum convolutional neural network (QCNN)—could process information more efficiently by using quantum states instead of classical bits.

Experimental proof shows quantum world is even stranger than previously thought

The quantum world is famously weird—a single particle can be in two places at once, its properties are undefined until they are measured, and the very act of measuring a quantum system changes everything. But according to new research published in Physical Review Letters, the quantum world is even stranger than previously thought.

From orbit to X-ray: Imaging the entire EURECA satellite to reveal hidden structural damage

Whether it’s a sprained ankle or a backpack at the airport, X-ray images are an everyday occurrence in many areas. Empa researchers at the Center for X-Ray Analytics have succeeded in taking images that are far less commonplace: In collaboration with the Swiss Space Center (now Space Innovation at EPFL) and the Swiss Museum of […]

Finding 40,000 asteroids before they find us

The number 40,000 might not sound particularly dramatic, but it represents humanity’s growing catalog of near-Earth asteroids, rocky remnants from the solar system’s violent birth that cross paths with our planet’s orbit. We’ve come a long way since 1898, when astronomers discovered the first of these wanderers, an asteroid called Eros.

Researchers reveal key role of interstellar polycyclic aromatic hydrocarbons in molecular clouds

Polycyclic aromatic hydrocarbons (PAHs) are important carriers of organic matter throughout the universe. As organic molecules, they play a central role in interstellar chemistry and are closely related to the origin of prebiotic molecules. Understanding how these organic compounds evolve in molecular clouds—the cold, dark cradles of star formation—is essential for tracing the origins of […]

Chang’e-6’s far-side lunar samples show strongly cohesive behavior

Lunar samples serve as a critical link between orbital remote sensing and ground-truth measurements. Previous sample-return missions—Apollo, Luna, and Chang’e-5—have collectively brought back approximately 383 kilograms of lunar soil and rock from the moon’s near side, advancing the understanding of lunar geological evolution and regolith properties. However, the absence of samples from the far side […]

Recently discovered X-ray transient traced to possible collapsar origin

Using various ground-based and space telescopes, an international team of astronomers has observed a recently discovered fast X-ray transient designated EP 241021a. Results of the multiwavelength observational campaign, published November 17 on the pre-print server arXiv, shed more light on the behavior and nature of this transient.

Quantum key distribution enables secure communication via hybrid and mobile channels

As part of the QuNET project, researchers have demonstrated how quantum key distribution works reliably via hybrid and mobile channels. The results are milestones for sovereign, quantum-secured communication in Germany and have been published in the New Journal of Physics.
