Per- and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals,” have emerged as a significant environmental concern due to their persistence in the environment and potential health risks. These substances are prolific in modern manufacturing, often found in consumer products designed to resist heat, stains, and water, such as waterproof clothing and non-stick cookware.
In recent years, the global demand for energy storage solutions has risen dramatically, driven by the increasing reliance on renewable energy sources. However, the limitations of lithium-ion batteries, particularly related to resource scarcity and environmental impacts, have triggered a search for alternative technologies. As electric vehicles and renewable energy systems expand, researchers are investigating batteries
The global landscape of infectious diseases has been fundamentally altered due to the COVID-19 pandemic, which catalyzed a significant reevaluation of public health priorities. As we gradually emerge from this unprecedented crisis, vigilance remains crucial. The focus has shifted toward other historical and potential threats, particularly malaria, HIV, and tuberculosis (TB), which together account for
The intriguing world of moiré superlattices has captivated the attention of physicists and material scientists alike, leading to exciting discoveries which challenge our conventional understanding of matter. Moiré superlattices are formed when two layers of two-dimensional (2D) materials, like graphene or transition metal dichalcogenides, are stacked with a slight angular misalignment. This minor adjustment in
The technological landscape has undergone a radical transformation over the past few decades, particularly with the evolution of smartphones, which now boast capabilities once reserved for supercomputers. As society advances towards an era dominated by artificial intelligence (AI) and the Internet of Things (IoT), the demand for more sophisticated and energy-efficient microchips has never been
Since the groundbreaking discovery of photoelectrochemical hydrogen evolution by Honda and Fujishima in 1972, the quest for efficient methods of hydrogen production through photocatalysis has been a focal point for researchers in energy science. Hydrogen is increasingly seen as a sustainable energy carrier, making the pursuit of innovative catalysts capable of improving hydrogen production rates
In recent years, the growing toll of extreme heat in urban environments has captured global attention, especially in the Global South. This alarming trend is backed by a new investigation highlighting the significant disparities in “cooling capacity” between urban areas in the Global North versus those in the Global South. While cities in affluent nations
Three years ago, a monumental event unfolded in the realm of astrophysics: the successful launch of the James Webb Space Telescope (JWST). This technological marvel, heralded as the most advanced telescope ever deployed, has since transformed our understanding of the Universe. With a developmental timeline spanning three decades, JWST’s brief operational history has yielded discoveries
The concept of the Universe’s expansion offers a fascinating glimpse into the nature of reality itself. As we delve into this cosmic enigma, using thoughtful analogies and contemporary theories, we can better understand both the mechanics of the Universe and the fundamental challenges faced by scientists. The Universe can be likened to a loaf of
The enigma of dark matter has captivated scientists for decades, primarily due to its invisible and elusive characteristics. While dark matter constitutes approximately 27% of the universe, unlike ordinary matter, it doesn’t emit, absorb, or reflect light, making it nearly undetectable. Recent advancements in astrophysics at the University of California, Berkeley, offer a tantalizing opportunity
Microplastics have become an integral part of our daily discourse, often mentioned in conversations about pollution, environmental degradation, and its impacts on health. Recent studies have painted a dire picture of their omnipresence, revealing that these minuscule plastic fragments can be found in various unexpected sources, including human tissues, ancient geological formations, and even the
