Imagine a material that defies common sense – one that becomes wider and fatter when pulled and narrower and thinner when compressed. These materials, known as auxetics, possess a range of extraordinary properties that make them ideal for a variety of applications, from sneaker insoles to bomb-resistant buildings. Despite their immense potential, the introduction of

The recent experiment conducted by researchers from the Paul-Drude-Institute for Solid State Electronics (PDI) in Berlin, Germany, and the Centro Atómico Bariloche and Instituto Balseiro (CAB-IB) in Argentina, has unveiled groundbreaking discoveries in the realm of time crystals. By observing a time crystal on a microscale semiconductor chip oscillating at several billion times per second,
The Sun, our beloved star, beats in multi-rhythmic patterns that are influenced by various periodicities, creating a complex dance of solar activity. The 11-year activity cycle of the Sun, known as the Schwabe cycle, has long been a subject of fascination and mystery for astronomers. Recent research suggests a potential link between the Sun’s activity
Recently, US officials reported the third human case of bird flu in the country, which is linked to the current outbreak of the virus in dairy cattle. This case was identified in a Michigan farm worker, making it the second person to be affected by the disease in the Midwestern state. The Centers for Disease
The European Union is leading the charge in revolutionizing the electric grid to enhance energy efficiency, reduce wastage, cut costs, and mitigate emissions. Dr. Anders Wulff, an engineer and CEO of Danish superconductor manufacturer SUBRA, is at the forefront of developing an innovative superconductor cable made of ceramics. This groundbreaking project, supported by EU funding,
The field of biocatalysis has made significant strides in optimizing natural enzyme functions for synthetic chemistry. However, UC Santa Barbara researchers, led by chemistry professor Yang Yang, are pushing the boundaries even further by delving into completely new enzymatic reactions that have never been seen before in either chemistry or biology. While most research in
In a groundbreaking study published in Advanced Science, a research group managed to achieve a remarkable giant magneto-superelasticity of 5% in a single crystal composed of Ni34Co8Cu8Mn36Ga14. This achievement opens up new possibilities in the field of material science by introducing arrays of ordered dislocations to shape preferentially oriented martensitic variants during a magnetically induced
In a recent study published in Materials Today Energy, a team of researchers successfully developed a 4-Amino-TEMPO derivative with photocatalytic properties. This derivative has been used to enhance the performance of fiber-shaped dye-sensitized solar cells (FDSSCs) and fiber-shaped organic light-emitting diodes (FOLEDs). The research team, led by Professor Chul-jin Ahn’s team at Changwon National University,
Urbanization in Africa is rapidly increasing, with no signs of slowing down. The urban population in the continent has more than doubled since the early 2000s, reaching over 600 million in 2020. If current growth trends continue, it is projected to double again by 2050. The rate of urban area expansion in Africa has outpaced
Robots are becoming increasingly prevalent in various environments, from home settings to industrial workplaces. In order to effectively carry out tasks in these diverse spaces, robots must possess the ability to grasp and manipulate a wide range of objects. To achieve this, developers have been exploring machine learning-based models to enhance robot manipulation skills. While
When we experience flow, we become completely absorbed in an activity, reaching a state of heightened concentration. This phenomenon, existing between boredom and stress, allows us to feel highly effective and in control, while losing track of time. Flow has been regarded as a positive experience with potential benefits for mental health. Origins of Flow
Japanese researchers have made a groundbreaking achievement by building the world’s first wooden satellite. This tiny cuboid craft, measuring 10 centimeters on each side, is the result of collaboration between scientists at Kyoto University and Sumitomo Forestry. The wooden material used in this experimental satellite is expected to burn up completely upon re-entry into the
Artificial Intelligence (AI) has the potential to significantly impact the peace and security landscape in South-East Asia. However, various systemic issues and gender biases present in widely used AI systems pose a substantial obstacle to the positive use of AI in this context. Research conducted by UN Women and the United Nations University Institute in
Proteins are essential components of living organisms, acting as molecular machines that carry out various processes vital for cell function. The three-dimensional structure of a protein plays a crucial role in its functionality, and analyzing these structures has become increasingly important in the field of protein research. In a recent study published in Nature Communications,
The fight against climate change often centers around farmland, where competing interests of food production and sustainable energy clash. Various strategies have been proposed to mitigate the impact of agriculture on the environment, including the use of marginal lands for energy crops. A recent study conducted by researchers at the University of Wisconsin-Madison sheds light
