By combining data from the DESI Legacy Imaging Surveys and the Gemini South telescope, astronomers have investigated three ultra-faint dwarf galaxies that reside in a region of space isolated from the environmental influence of larger objects. The galaxies, located in the direction of NGC 300, were found to contain only very old stars, supporting the

An international team of engineers has developed an innovative, scalable method for creating topography-patterned aluminum surfaces, enhancing liquid transport properties critical for applications in electronics cooling, self-cleaning technologies and anti-icing systems.

Methane from the destroyed Nord Stream pipelines spread over a large part of the southern Baltic Sea and remained for several months. Methane from the destroyed Nord Stream pipelines spread over a large part of the southern Baltic Sea and remained for several months. This is according to a new study by researchers from the

A milestone in graphene research: Chemists have succeeded in controlling the passage of halide ions by deliberately introducing defects into a two-layer nanographene system. Their paper shows new perspectives for applications in water filtration or sensor technology. Graphene is an extremely thin, flexible and resistant material made of pure carbon. It forms layers that consist

For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it -- the flickering star is 2.2 million light-years away, and is 1/100,000th the brightness of the faintest star visible to the human eye. Yet, a century ago, its

Hot Jupiters are giant planets initially known to orbit alone close to their star. During their migration towards their star, these planets were thought to accrete or eject any other planets present. However, this paradigm has been overturned by recent observations, and the final blow could come from a new study demonstrating the existence of

New observational data and simulation models have confirmed a new type of planet unlike anything found in the Solar System. This provides another piece of the puzzle to understand how planets and planetary systems form. New observational data from the James Webb Space Telescope and simulation models have confirmed a new type of planet unlike

Engineers have demonstrated a well-known quantum thought experiment in the real world. Their findings deliver a new and more robust way to perform quantum computations and they have important implications for error correction, one of the biggest obstacles standing between them and a working quantum computer. UNSW engineers have demonstrated a well-known quantum thought experiment

Researchers have published a study describing how quasiparticles called polarons behave in tellurene, a nanomaterial first synthesized in 2017 that is made up of tiny chains of tellurium atoms and has properties useful in sensing, electronic, optical and energy devices. To describe how matter works at infinitesimal scales, researchers designate collective behaviors with single concepts

Federal reservoirs could help meet the country's solar energy needs, according to a new study. Geospatial scientists and senior legal and regulatory analyst quantified exactly how much energy could be generated from floating solar panel projects installed on federally owned or regulated reservoirs. Federal reservoirs could help meet the country's solar energy needs, according to

AI applications like ChatGPT are based on artificial neural networks that, in many respects, imitate the nerve cells in our brains. They are trained with vast quantities of data on high-performance computers, gobbling up massive amounts of energy in the process. Spiking neurons, which are much less energy-intensive, could be one solution to this problem.

How can we ensure that life-saving drugs or genetic therapies reach their intended target cells without causing harmful side effects? Researchers have taken an important step to answer this question. They have developed a method that, for the first time, enables the precise detection of nanocarriers -- tiny transport vehicles -- throughout the entire mouse
