The pursuit of sustainable energy solutions has fueled significant interest in hydrogen, the simplest and lightest of all elements. Researchers have long recognized the potential of hydrogen as a clean energy resource, particularly through its isotopes: protium, deuterium, and tritium. A recent collaborative effort by scientists from Leipzig University and TU Dresden has resulted in
Chemistry
At the forefront of nanotechnology, researchers from the Technical University of Munich (TUM) have achieved a significant breakthrough by designing an artificial motor utilizing supramolecular structures. This intricately engineered wind-up motor is not only minuscule but also exhibits remarkable power generation capabilities. Composed of specially formulated peptide ribbons, the motor employs chemical energy to trigger
When most people think of oysters, their minds often go to culinary delights served on ice or cooked to perfection. However, these aquatic organisms are much more than just a delicacy; they hold secrets that could revolutionize materials science. Particularly noteworthy are the Etheria elliptica oysters, found in Africa’s rivers and lakes, which produce a
In the realm of photocatalysis, understanding energy transfer (EnT) processes has become increasingly pivotal. Dr. Albert Solé-Daura and Professor Feliu Maseras have made strides in this area by harnessing the traditional Marcus theory, typically reserved for electron transfer modeling, to provide fresh insights into the energetic landscapes of EnT. Their innovative application of this theory,
Samarium, a rare earth element, has carved a niche in the field of organic chemistry due to its unique capacity for facilitating single-electron transfer reactions. Among its various compounds, samarium iodide (SmI2) stands out for its stability and efficacy at ambient temperatures, making it an essential reagent in synthesizing pharmaceuticals and bioactive compounds. However, traditional
In a remarkable turn of events for microbiology and genetics, recent research led by Samuel Schwab, a Ph.D. candidate at the Leiden Institute of Chemistry, has unveiled an unexpected level of complexity in the histones of single-celled organisms, specifically bacteria and archaea. Long overshadowed by the implications of histone function in multicellular life forms, these
Crystallization is often associated with processes that occur far from the natural world, such as the creation of synthetic gems or the production of illicit substances. However, nature has its own set of remarkable crystal artisans. Birds, fish, and even reptiles wield the remarkable ability to produce crystals intrinsically within their biological framework.

In a groundbreaking study spearheaded by a team at Rice University, researchers have begun to unravel the complex interplay between cholesterol and cell membranes. Led by Jason Hafner, a professor specializing in physics and chemistry, the findings present a significant advance in our comprehension of how cholesterol shapes these vital structures. The study, recently published
As the planet grapples with rising levels of atmospheric carbon dioxide (CO2), the implications extend far beyond climate change. Increasing evidence suggests that excess CO2 can impact cellular function, presenting potential hazards to human health. Notably, the interaction between CO2 and hydrogen peroxide (H2O2)—a critical molecule in various biological processes—results in the formation of a
Cancer cells are characterized by their accelerated growth, which is often fueled by mutations and aberrations in metabolic processes. One vital enzyme in this context is serine hydroxymethyltransferase (SHMT), a metabolic enzyme that plays a significant role in one-carbon metabolism—a pathway essential for nucleic acid synthesis and cell division. Recent discoveries regarding SHMT have shown
The quest for sustainable energy solutions has catapulted hydrogen gas to the forefront of green technology discourse. Renowned for its high energy density and lack of carbon emissions when utilized, hydrogen embodies potential as a clean fuel alternative for the future. Indeed, hydrogen is the most plentiful element in the universe. However, its sheer abundance
Water quality has become a pressing concern globally, particularly with the increasing levels of pharmaceutical micropollutants found in our rivers, lakes, and wastewater systems. These contaminants often originate from the excretion of medications or disposal of expired pharmaceuticals, which evade traditional wastewater treatment facilities. As a result, a substantial variety of active pharmaceutical ingredients (APIs)
The recent Nobel Prize in Chemistry has captured global attention, recognizing the groundbreaking contributions of three distinguished scientists—Demis Hassabis, John Jumper, and David Baker—who have significantly advanced our understanding of proteins, the essential building blocks of life. This award is not merely a tribute to individual accomplishments but a celebration of the transformative potential these
For countless children, the allure of superheroes like Spider-Man has sparked dreams of swinging between skyscrapers, web-shooting, and foiling villains with effortless agility. This whimsical imagination has now been taken seriously by researchers at Tufts University, culminating in the development of cutting-edge web-slinging technology. Their work, published in the journal Advanced Functional Materials, delineates a
Covalent bonds form the backbone of organic chemistry, connecting atoms through the sharing of electron pairs. In 1931, Linus Pauling, a trailblazer in the field, theorized the existence of bonds formed by the sharing of a single, unpaired electron. However, these single-electron bonds were believed to be inherently weaker than their double-electron counterparts. Despite considerable
