The idea of having living fungi cover your body might not be the most appealing thing in the world. But what if it was part of a clothing fabric that could change color, protect you from UV rays and even repair its own tears? Those are just some of the possibilities of a new material described in a paper published in the journal Science.
Researchers at Rensselaer Polytechnic Institute (RPI) have found that today's leading artificial intelligence tools for predicting protein structures routinely generate results that are physically and chemically impossible, exposing critical blind spots in how AI is being applied across scientific research. The work, published in the Proceedings of the National Academy of Sciences, serves as a cautionary reminder that AI still requires human oversight and physics-based verification to produce reliable results in the lab.
Photocatalytic reduction of CO2 offers a promising approach to storing energy from intermittent sunlight in carbon-containing fuels and chemicals, thereby enabling carbon recycling. Single-atom Cu catalysts have attracted attention because they enhance CO2 photoreduction. However, the roles of single-atom active sites and adjacent atoms in these catalysts have not been well understood.
Sand has a way of getting everywhere on a beach day—and for some, it can make or break the whole trip. There's the way it whips through the air just as sandwiches are being unwrapped, the way it turns blisteringly hot underfoot by midday, and the way it stubbornly clings to every piece of clothing.
To improve carbon recycling and reduce emissions, researchers at Science Tokyo developed iron-substituted calcium titanate (Fe-doped CaTiO3) as an environmentally friendly support material for chemical looping, a process that converts carbon dioxide (CO2) into carbon monoxide for fuel and chemical production. By substituting iron into CaTiO3, the material gained oxygen vacancies and improved ion and electron transport, accelerating CO2 conversion. Built from widely available, low-cost elements, the material could help enable scalable carbon recycling.
Biomolecular condensates are ubiquitous in living cells, including bacteria, viruses, plants and mammalian systems. These membraneless bodies, or molecular communities made up of DNA, RNA and proteins, are where molecules large and small within the cell come together to coordinate various biochemical reactions.
A new study suggests that simple molecules on early Earth may have worked together to create more stable, cell-like structures, offering fresh clues about one of science's biggest questions: how life began. Led by Dr. Moran Frenkel-Pinter of Hebrew University and her postdoctoral researcher, Dr. Rotem Edri, the research shows that two types of simple molecules, fatty acids and hydroxy acids, can combine to create structures that are stronger and more stable than either molecule can form alone.
Complex simulations—the most intricate of their kind to date—carried out by an international research team led by scientists at Heidelberg University's Institute for Physical Chemistry, have revealed how water governs the way protons move through it. Using their modeling, researchers from Cambridge (U.K.), Bochum, Dijon (France) and Heidelberg were able to trace, in full quantum detail, the movements of a proton shared among six water molecules. At its core, the work addresses how a proton moves through water: not as a single particle drifting along, but by "hopping" from one molecule to the next.
Plastic recycling could become far more effective thanks to a new technique that restores the strength of damaged engineering plastics by repairing them at the molecular level.
A naturally abundant plant material best known for giving trees and crops their strength may one day help repair broken bones, according to a new study led by postdoctoral researcher Dr. Srinath Palakurthy and Professor Rivka Elbaum of the Hebrew University of Jerusalem.
Seoul National University (SNU) College of Engineering announced that a research team led by Professor Jeong Woo Han of the Department of Materials Science and Engineering has developed a new nanostructured catalyst with up to 14.4 times the greenhouse gas decomposition performance of conventional commercial catalysts.
Nitrate contamination originating from agricultural runoff, industrial wastewater and municipal effluents is a growing global environmental problem. At the same time, ammonia has emerged as a key chemical feedstock and an attractive carbon-free energy carrier for a sustainable society.
A research team led by Dongwoo Lee, an associate professor in the School of Mechanical Engineering at Sungkyunkwan University (SKKU), and Yanhui Liu of the Institute of Physics, Chinese Academy of Sciences (CAS), has developed a new electrical resistivity-based indicator for rapidly screening alloy compositions with high glass-forming ability.
Ethanol is an alcohol used in a vast number of industrial and household applications. When dehydrogenated—in this case, stripped of some of its hydrogen atoms—it yields another important compound: acetaldehyde, which is used to make resins, dyes, perfumes and synthetic flavors, among many other products. But currently available catalysts for ethanol dehydrogenation suffer from deactivation, poor performance over time and unwanted side reactions.
Researchers at the University of Warwick and spinout company Verdel Instruments have successfully demonstrated two-dimensional mass spectrometry (2DMS) on a benchtop instrument, making this powerful technique practical and affordable for everyday laboratory use.
