Jupiter’s moon Europa is a fascinating target for study. Data from the Galileo spacecraft’s Solid State Imager showed that Europa, one of Jupiter’s moons, has a geologically young and varied surface featuring formations like pits, spots, and cryolava domes. A new study has revealed more about the composition of the cryovolcanoes and their domes but also and more excitingly perhaps that they may even provide some form of habitation as we explore the Solar System!
The search for life involves the most sophisticated observational machines known to humanity. They peer out across the light-years, looking for some proof - any proof - that other life exists, out there. What if, despite all our efforts, those observations turn up NO evidence of life elsewhere in our Milky Way Galaxy?
Titan is Saturn's largest moon, with a thick atmosphere and liquid methane lakes, making it the only place besides Earth with stable liquid on its surface. A new paper reveals how a team of researchers have compared real craters on Titan with computer-simulated ones to determine the thickness of its icy shell. This information is important for understanding Titan's interior structure, how it evolved thermally, and its potential to produce organic molecules, making it significant for astrobiological research.
NGC 1514 is a planetary nebula about 1500 light years away. William Herschel discovered it in 1790, and its discovery made him rethink the nature of nebulae. It's been imaged many times by modern telescopes, and each time a more capable one revisits it, astronomers learn more about it. The JWST is the latest to observe the curious nebula, and its observations help explain the unusual object.
Identifying a key protein's role could improve the common mental health medications and point to new treatments for inflammation-related diseases, a medicinal chemist says.
There are roof shapes and ratios that maximize heat retainment and energy efficiency and, interestingly, ancient Italian architects and builders seemed to know it, too.
We've long known that black holes can produce powerful jets of ionized gas. These jets stream away from the black hole at nearly the speed of light. Jets produced by supermassive black holes are so powerful they are seen as quasars from billions of light-years away. But when you think about it, jets are a bit counterintuitive. Black holes trap and consume material through their tremendous gravity, so how can they push streams of material away? A recent study in Publications of the Astronomical Society of Japan shows how it works.
Ice cores that record 1.2 million years of Earth’s atmosphere are on their way to Europe to be analysed, and an Australian drilling team is hoping to go even further back in time
A groundbreaking open-source computer program uses artificial intelligence to analyze videos of patients with Parkinson's disease and other movement disorders. The tool, called VisionMD, helps doctors more accurately monitor subtle motor changes, improving patient care and advancing clinical research.
Puppies’ performance in cognitive tests at 3 to 7 months old can give a strong indication of their personalities and trainability as adults
Neural networks are one typical structure on which artificial intelligence can be based. The term neural describes their learning ability, which to some extent mimics the functioning of neurons in our brains. To be able to work, several key ingredients are required: one of them is an activation function which introduces nonlinearity into the structure. A photonic activation function has important advantages for the implementation of optical neural networks based on light propagation. Researchers have now experimentally shown an all-optically controlled activation function based on traveling sound waves. It is suitable for a wide range of optical neural network approaches and allows operation in the so-called synthetic frequency dimension.

Microplastics and the much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in organs, blood and other body fluids. Scientists have now been able to develop a method for detecting and quantifying nanoplastics in transparent body fluids and determining their chemical composition.
Researchers may have answered one of space science's long-running questions -- and it could change our understanding of how life began. Carbon-rich asteroids are abundant in space yet make up less than 5 per cent of meteorites found on Earth.
Researchers have developed a new forecasting model that helps companies more accurately estimate how many customers are interested in a product -- even when key data is missing. The study introduces a mathematical modeling method that enables businesses to estimate customer interest beyond just completed transactions and traditional forecasting techniques. The approach offers a more precise way to understand demand, optimize operations and improve decision-making.

A team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA A few years ago, the advent of technology known as CRISPR was a major breakthrough in the scientific world. Developed from a derivative of the immune system of bacteria, CRISPR enables double strands of nucleotides in deoxyribonucleic acid (DNA) to be cut. This makes it possible to specifically modify a targeted gene in plant, animal and human cells. Ultimately, CRISPR became a preferred method in the search for treatments for acquired or hereditary diseases.
A new study by neuroscientists shows that our brain deals with different forms of visual uncertainty during movements in distinct ways. Depending on the type of uncertainty, planning and execution of movements in the brain are affected differently. These findings could help to optimize brain-computer interfaces that, for example, help people with paralysis to control prostheses or computers with their thoughts alone.
