In recent years, covalent organic frameworks (COFs) have emerged as a promising class of materials in the field of environmental science and engineering. These crystalline structures, comprised of small, repeating molecular units, exhibit exceptional properties such as high porosity and a tunable surface area, making them highly versatile. With applications ranging from gas storage and

In recent years, discussions surrounding climate change have predominantly centered on terrestrial ecosystems, often overlooking the significant role that inland waters—such as lakes, rivers, and streams—play in greenhouse gas emissions. This gap in our understanding is critical, especially in light of emerging research from Umeå University that underscores how carbon exchanges between land and freshwater
On a seemingly ordinary Monday, a significant disruption to Verizon’s cellular services sent shockwaves across the nation. Reports of disrupted services flooded in, indicating that tens of thousands of customers were left without cell coverage. Utilizing data from outage monitoring platform DownDetector, it was found that more than 100,000 complaints surfaced within a mere two
On October 3, 2024, the Sun astonished astronomers and skywatchers alike by unleashing an X9.0-class solar flare, marking the most powerful eruption in nearly seven years. This extraordinary event was not just a standalone phenomenon, as it arrived alongside a halo coronal mass ejection (CME) directed straight toward Earth. This combination of a potent flare
Aquaphobia, an overwhelming fear of water, can significantly impact a person’s quality of life. This anxiety often exceeds a mere discomfort, morphing into a debilitating condition that restricts individuals from participating in everyday recreational activities. While some who suffer from aquaphobia may dread swimming pools and oceans, others may experience symptoms even when faced with
The concept of the Anthropocene has emerged in recent discussions about geological epochs, signaling a profound transformation in Earth’s history instigated by human activities. This term, popularized by Nobel laureate Paul Crutzen in 2002, suggests that the Holocene—the epoch that began approximately 11,700 years ago at the end of the last Ice Age—has given way
Organic fluorophores have revolutionized various scientific fields, particularly in medical diagnostics and bioimaging. Their unique ability to fluoresce — absorbing light at one wavelength and emitting it at another — has made them indispensable in applications ranging from cancer detection to genetic research. As the demand for these compounds continues to rise, so too does
October 2023 commenced with an awe-inspiring display from our nearest star, the Sun. As we transition into the spooky season, an immense solar flare and a coronal mass ejection (CME), both incredibly potent, have sparked interest and concern among scientists and sky-gazers alike. On October 1, the Sun unleashed an X7.1 flare, marking it as
Recent advancements in nonlinear optical metasurfaces have the potential to redefine communication technologies and medical diagnostics. These uniquely engineered surfaces, which are smaller than light’s wavelength, signify a promising direction for future developments such as quantum light sources and innovative diagnostic devices. Led by Professor Jongwon Lee from the Department of Electrical Engineering at UNIST,
Since their illustrious launches in 1977, the Voyager spacecraft have continually dazzled scientists and space enthusiasts alike with their unprecedented voyages beyond the planets of our Solar System. Voyager 1 and Voyager 2, through their groundbreaking missions, have not only explored our immediate cosmic neighborhood but have also become humanity’s first ambassadors to the interstellar
In recent decades, a troubling trend has emerged in global public health: the alarming rise of myopia, commonly known as shortsightedness, particularly among children and adolescents. Current projections indicate catastrophic outcomes, with estimates suggesting that by 2050, over 740 million youth may experience difficulties in seeing distant objects. A comprehensive analysis led by researchers from
In the face of rising global temperatures and intensifying heatwaves, urban areas are becoming increasingly inhospitable. The phenomenon known as the “urban heat island” effect leads cities to absorb and retain more heat relative to surrounding rural areas, creating dangerously high temperature disparities. A recent study conducted by researchers from University College London (UCL) and
