In our increasingly digital world, smartphones serve as indispensable tools, handling everything from personal communication to financial transactions. As these devices have become more ingrained in our daily lives, so too has the need for robust security measures to protect sensitive data. However, a recent study conducted by researchers at Graz University of Technology (TU

Bacteria have long been a formidable adversary in the battle against infectious diseases. These microorganisms have evolved a variety of protective strategies to survive hostile environments, evade host immune responses, and persist despite medical interventions. A critical area of research focuses on the structural elements that allow pathogenic bacteria to fortify themselves, particularly through the
Per- and polyfluoroalkyl substances (PFAS) have emerged as significant pollutants due to their robust chemical structure, which leads to immense persistence in the environment. These man-made compounds, commonly referred to as “forever chemicals,” are utilized in a wide array of products, from non-stick cookware to water-repellent fabrics. Unfortunately, their strong chemical bonds make them resistant
For decades, scientists have speculated about the origins of water in the cosmos, often dating its formation to much later than previously believed. However, recent advancements in astronomical modeling suggest that water, one of life’s essential compounds, might have emerged much earlier than the conventional timeline posited by previous theories. New simulations led by cosmologist
Shock experiments stand at the forefront of materials science, particularly when examining how materials behave under extreme conditions, such as those encountered during cosmic events like meteorite impacts. These experiments deliberately induce shock waves within materials to observe changes in their mechanical and electronic properties. However, while there is a wealth of research focusing on
In early 2025, the landscape of public health shifted dramatically as influenza rates surged to levels not witnessed in over a decade and a half. For the first time since the onset of the COVID-19 pandemic, the number of flu cases surpassed those of COVID-19 infections and hospitalizations. The Centers for Disease Control and Prevention
In an era increasingly dominated by digital devices, our smartphones have become almost an extension of ourselves. The ubiquitous nature of these devices raises important questions about their impact on our cognitive functions and overall mental health. A recent study conducted by researchers from Heidelberg University and the University of Cologne sheds light on the
Fast radio bursts (FRBs) continue to captivate and perplex astronomers around the globe. These brief, intense pulses of radio waves, which release energy equivalent to billions of suns within milliseconds, have sparked a wave of questions regarding their origins and nature. Unlike typical cosmic phenomena, FRBs exhibit a unique volatility; most appear as one-off events,
Nanozymes represent an innovative frontier in nanotechnology, designed to closely imitate the catalytic function of natural enzymes. These engineered nanomaterials open doors to numerous applications, particularly in fields like biomedicine, environmental science, and chemical engineering. However, while their inorganic counterparts have made significant strides since their inception, they bring with them a set of inherent
In recent years, there has been an alarming increase in concern regarding climate change, particularly among scientists across various academic disciplines. A recent study led by researchers from the University of Amsterdam reveals that an overwhelming majority of scientists recognize climate change as an existential threat that demands immediate action. Published in the prestigious journal
Firefly Aerospace’s Blue Ghost lunar lander is making waves in the aerospace industry as it prepares for its first landing on the Moon. This innovative mission signifies a leap forward for both the company and NASA, as it marks the start of multiple planned missions aimed at exploring and ultimately establishing a presence on our
In the context of an ever-urbanizing world, the demand for comprehensive safety measures against fire hazards has reached a critical juncture. The rise in high-density developments, particularly in dynamic urban landscapes like Hong Kong, necessitates innovative solutions to tackle the complexities of firefighting and emergency management. The Hong Kong Polytechnic University (PolyU) stands at the
