Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a researcher realized that the Solar System's biggest moon's axis has shifted as a result of the impact, which confirmed that the asteroid was around 20 times larger than the one that ended the age of the dinosaurs on Earth, and caused

Over billions of years, the universe's stars and galaxies shined their light into space, leaving behind an imperceptibly faint night light known as the cosmic optical background. NASA's New Horizons spacecraft has traveled to the edge of Earth's solar system and captured the most accurate measurement of this glow to date. Scientists have traveled to

A recently developed block copolymer could help push the limits of integration and miniaturization in semiconductor manufacturing, report scientists. Chemically tailored for reliable directed self-assembly, the proposed compound can arrange itself into perpendicular lamellar structures whose half-pitch width is less than 10 nanometers, outperforming conventional and widely used block copolymers. A recently developed block copolymer

Scientists have developed an AI tool that creates detailed models of cellular metabolism, making it easier to understand how cells function. Understanding how cells process nutrients and produce energy -- collectively known as metabolism -- is essential in biology. However, analyzing the vast amounts of data on cellular processes to determine metabolic states is a

Researchers created a new quantum state of matter, dubbed a higher-order topological magnet, that may address key issues in quantum technology. When different quantum states combine, new collective states of matter can emerge. In the quantum realm, combining components such as atoms that possess quantum effects can give rise to macroscopic quantum states of matter

A collaborative research team has identified the world's first multiple Majorana zero modes (MZMs) in a single vortex of the superconducting topological crystalline insulator SnTe and exploited crystal symmetry to control the coupling between the MZMs. This discovery offers a new pathway to realizing fault-tolerant quantum computers. A collaborative research team led by Prof. Junwei

It's not easy being green. Scientists for years have made small red and blue lasers, but other colors, including green, have been a challenge. A team has now filled this technology gap by creating orange, yellow and green lasers tiny enough to fit on a chip, opening up a wide range of applications in quantum

While some microbes can make people sick or spoil food, others are critical for survival. These tiny organisms can also be engineered to make specific molecules. Researchers have rewired one such microbe to help tackle greenhouse gases in the atmosphere: It takes in carbon dioxide (CO2) gas and produces mevalonate, a useful building block for

To understand the mysteries surrounding black holes, researchers at Tohoku University have created a simulation of accretion disk turbulence that possesses the highest-resolution currently available. Researchers at Tohoku University and Utsunomiya University have made a breakthrough in understanding the complex nature of turbulence in structures called "accretion disks" surrounding black holes, using state-of-the-art supercomputers to

Researchers have used vinegar vapor to dramatically improve UV sensors in a cheap, room-temperature process leading to better wearable devices. Researchers at Macquarie University have developed a new way to produce ultraviolet (UV) light sensors, which could lead to more efficient and flexible wearable devices. The study, published in the journal Small in July, shows

Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT-IR spectroscopy, researchers succeeded in observing and identifying the reactive electron species for photocatalytic hydrogen evolution. In contrast to the traditional belief, this study demonstrates that not the free electrons in metal cocatalysts but the electrons trapped in the periphery of cocatalysts directly contribute

Researchers have successfully simulated higher-order topological (HOT) lattices with unprecedented accuracy using digital quantum computers. These complex lattice structures can help us understand advanced quantum materials with robust quantum states that are highly sought after in various technological applications. Researchers from the National University of Singapore (NUS) have successfully simulated higher-order topological (HOT) lattices with
