Recent groundbreaking research led by an international team including UCL scientists has fundamentally redefined our understanding of the carbon-storage capabilities of miombo woodlands in Mozambique. Utilizing advanced technology, researchers discovered that these ecosystems, historically overlooked in terms of their carbon potential, could store 1.5 to 2.2 times more carbon than previously estimated by conventional methods.
The field of carbohydrate chemistry has long been overshadowed by the complexities surrounding the synthesis of glycosides and glycoproteins. The challenges include not just the intricate structures of carbohydrates, but also the conventional need for protecting groups in chemical reactions. These hurdles have reduced the efficiency and increased the waste associated with carbohydrate synthesis, hindering
In an extraordinary revelation, astronomers have recently captured the breathtaking moment when one galaxy collides with another, propelled by an intense beam of radiation emanating from its central black hole. This stunning event, dubbed the “cosmic joust,” represents a landmark in our understanding of galactic interactions. The massive energy at play is altering the fabric
On May 20, 2025, the Food and Drug Administration (FDA) took a bold step in reshaping the landscape of COVID-19 vaccination recommendations. By shifting its focus toward a risk-based framework, the agency is decisively limiting the eligibility for receiving the COVID-19 vaccine to adults aged 65 and older and individuals with specific health conditions, including
Recent studies have shed light on an intricate and relatively obscure concept known as the human oxidation field (HOF). Discovered only in 2022, this phenomenon refers to the chemical shield our bodies create when our skin oils react with airborne pollutants, particularly ozone. This shield generates hydroxyl (OH) radicals, often characterized as nature’s own atmospheric
The cosmos has a way of constantly challenging our understanding of its vast intricacies. Recently, astronomers unveiled a massive spiral galaxy, identified as J0107a, that emerged just 2.6 billion years after the Big Bang. What’s stunning is that this galaxy features a remarkably evolved structure—a stable galactic bar—traditionally thought to characterize older galaxies. The implications
In an astonishing revelation from China’s Tiangong space station, researchers have identified a previously unknown bacterium, which they’ve aptly named Niallia tiangongensis. This discovery offers both insight and concern as humanity prepares for prolonged missions in the unforgiving realms of space. Extracted from swabs collected by the Shenzhou-15 crew in May 2023, this microorganism presents
In a remarkable advancement in the field of regenerative medicine, researchers at the University of Virginia have pioneered a method that could revolutionize organ fabrication. Led by assistant professor Liheng Cai and Ph.D. student Jinchang Zhu, the team has developed innovative biomaterials that aspire to closely mimic human tissue properties. In their recent publication in
Recent findings by a coalition of non-governmental organizations have revealed a disturbing presence of substances commonly referred to as “forever chemicals” in the drinking water across multiple regions of Europe. These chemicals, specifically per- and polyfluoroalkyl substances (PFAS), which are extensively used in various industries, have been identified in alarming levels in both bottled and
In the rapidly evolving landscape of data storage, researchers from the Helmholtz-Zentrum Dresden-Rossendorf and several German universities have embarked on a groundbreaking journey that may redefine our understanding of how information is stored and processed. Their recent findings, published in *Advanced Electronic Materials*, reveal that not only individual bits can be stored but entire sequences
At 115 years old, Ethel Caterham from Surrey has recently earned the title of the oldest living person. Her remarkable longevity prompts many to inquire about the factors that have contributed to her exceptional life span. While every supercentenarian may possess unique genetic and lifestyle traits, there are certain habits and practices common among long-lived
Taurine has often been celebrated for its numerous health benefits, especially its relationship with energy production and cellular health. Found naturally in our bodies and in various food sources like seafood and meat, taurine’s reputation is accompanied by its presence in popular energy drinks. However, emerging research signals a need for a critical reevaluation of
On the night of May 17, 2025, stargazers across the United States caught a breathtaking spectacle: a radiant stream of whitish light cascading across the sky. Reports of this mesmerizing phenomenon came pouring in from various states, with observers as far south as New Mexico transfixed by the visual treat. Initially, this display was attributed
In a stunning discovery that captured the imagination of astronomers and the public alike, the TRAPPIST-1 system emerged as a focal point for the search for extraterrestrial life in February 2017. Located approximately 40 light-years from Earth, this extraordinary system is home to seven Earth-sized planets orbiting a red dwarf star. Scientists have been eager
