Astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained in July and August 2023. They show giant, hot bubbles of gas, 75 times the size of the Sun, appearing on the

Phase separation, when molecules part like oil and water, works alongside oxygen diffusion to help memristors -- electrical components that store information using electrical resistance -- retain information even after the power is shut off, according to a recent study.

A new article examines how the flexibility of containers affect how fast they drain. As Rohit Velankar, now a senior at Fox Chapel Area High School, poured juice into a glass, he could feel that the rhythmic glug, glug, glug was flexing the walls of the carton. Rohit pondered the sound, and wondered if a

Researchers have introduced a novel method for converting the greenhouse gas carbon dioxide (CO2) into ethanol, a sustainable fuel. This significant advancement could pave the way for more environmentally friendly and economically viable alternatives to fossil fuels. In a cutting-edge study published in the journal Energy & Environmental Science, researchers from the Interface Science Department

Researchers report on a new defect passivation strategy for improved power conversion efficiency and stability of perovskite solar cells. Polycrystalline formamidinium lead iodide (FAPbI3), widely used for making perovskite-based solar cells due to its superior optoelectronic properties, suffers from defects in its crystalline structure. Researchers from the Gwangju Institute of Science and Technology (GIST) introduced

A study has developed an innovative method that overcomes the limitations of traditional additive manufacturing (3D printing), significantly simplifying and accelerating the production of geometrically complex cellular ceramics. This groundbreaking approach has the potential to revolutionize the design and processing of multifarious ceramic materials, opening up new possibilities for new applications in energy, electronics, and

An AI-powered tool can distinguish dark matter's elusive effects from other cosmic phenomena, which could bring us closer to unlocking the secrets of dark matter. Dark matter is the invisible force holding the universe together -- or so we think. It makes up around 85% of all matter and around 27% of the universe's contents

Physicists present a nanometer-sized light antenna with electrically modulated surface properties -- a breakthrough that could pave the way for faster computer chips. Physicists from Würzburg present a nanometre-sized light antenna with electrically modulated surface properties -- a breakthrough that could pave the way for faster computer chips. Today's computers reach their physical limits when

Every living organism uses tiny quantities of metals to carry out biological functions, including breathing, transcribing DNA, turning food into energy, or any number of essential life processes.

Chemists discover how key contrast agent works, paving a way to create new markers needed for correlative microscopy that can image the structure and signaling of cells at the same time. Two labs at the University of Utah's Department of Chemistry joined forces to improve imaging tools that may soon enable scientists to better observe

The MXene class of materials has many talents. An international team has now demonstrated that MXenes, properly functionalized, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the best metal oxide catalysts currently available. The team is now extensively characterizing these MXene catalysts for water
