Calcite, a crystalline form of calcium carbonate, is a mineral with a rhombohedral appearance that is abundant on Earth. As a major component of limestone and marble, calcite is known for its stability compared to other forms of calcium carbonate, such as aragonite and vaterite. The internal structure of calcite is a key factor in

Siemens, the German industrial giant, has unveiled a groundbreaking urban development project in the heart of Berlin, specifically in the area known as Siemensstadt. With an impressive investment of 4.5 billion euros, the Siemensstadt Square project aims to breathe new life into this historic area, where Siemens once thrived before the tumultuous events of the
In a world where vision loss and visual impairment are significant concerns, there has been a groundbreaking invention by researchers from The Hong Kong Polytechnic University (PolyU) and The University of Waterloo. This device, utilizing Augmented Reality (AR) technology, aims to revolutionize navigation for visually impaired individuals, offering them a newfound sense of independence and
Food safety is a critical issue that affects consumers worldwide. The constant threat of contamination from harmful pathogens can lead to serious illnesses and even fatalities. Traditional methods of pathogen detection, such as cell culture and DNA sequencing, have limitations that make it difficult to detect contaminants in a timely and efficient manner. These methods
The pursuit of accurately simulating quantum particles using a computer made up of quantum particles has been a long-standing goal for physicists. The recent collaboration between scientists at Forschungszentrum Jülich and colleagues from Slovenia has made significant progress in this area. By using a quantum annealer to model real-life quantum material, they have demonstrated the
For years, the process of testing for asbestos in construction materials and air samples has relied heavily on transmission electron microscopy (TEM). However, recent research conducted by the National Institute of Standards and Technology (NIST) has suggested that scanning electron microscopy (SEM) may be a viable alternative to TEM for asbestos identification and classification. Asbestos,
Around 183 million years ago, during the Toarcian Oceanic Anoxic Event (T-OAE), massive volcanic activity in what is now South Africa released an estimated 20,500 gigatons of carbon dioxide (CO2) into the ocean and atmosphere. This event, which lasted for 300 to 500 thousand years, resulted in a significant lack of oxygen in the water,
In the realm of electronics engineering and material science, researchers have long been on the quest to discover materials that can enhance the performance of electronic devices beyond the limitations imposed by silicon-based transistors. Two-dimensional (2D) semiconductors have emerged as promising candidates for the development of high-performance transistors due to their unique properties. These materials
Garlic, a commonly used ingredient in various cuisines around the world, has been found to have significant impacts on blood sugar and cholesterol levels. Research conducted by scientists from Southeast University and Xizang Minzu University in China revealed some interesting findings that shed light on the positive effects of incorporating garlic into our diet. The
Boeing’s Starliner capsule, a key part of NASA’s Commercial Crew Program, has faced setbacks during its recent operation to the International Space Station. Due to helium leaks and thruster problems, NASA has decided to delay the return of two astronauts, Butch Wilmore and Suni Williams, indefinitely. The agency announced on Friday that they no longer
A recent Canadian study has found a significant increase in the risk of teenagers developing a psychotic disorder associated with cannabis use. The study suggests that the potency of cannabis today is much higher than it was in the past, leading to a stronger association between cannabis use and psychotic disorders. The study focused on
The Aral Sea, located in Central Asia, has been significantly impacted by both climate change and human activities. Due to these factors, the surface area of the Aral Sea has been steadily decreasing, leading to what can only be described as a regional ecological crisis. The reduction in size of the Aral Sea has had
