Today, nearly all of this critical mineral must be mined and processed and, in the United States, imported. https://phys.org/news/2026-07-graphite-newly.html Analytical Chemistry Thu, 30 Jul 2026 21:00:01 EDT news704646526 Algae are increasingly being explored as sustainable "living factories" that can convert sunlight and carbon dioxide into renewable fuels, plastics, pharmaceuticals and other valuable products. https://phys.org/news/2026-07-redistributing-sunlight-boosts-algae-biomass.html Biochemistry Thu, 30 Jul 2026 17:10:02 EDT news704647981 Pharmaceutical drugs often rely on chemical compounds found in the body. Take phosphate, a common compound cells use as a chemical switch. In a process called phosphorylation, cells can add a phosphate to a molecule and turn its function on. When the function is no longer needed, cells can remove the phosphate through dephosphorylation, turning the molecule back off. https://phys.org/news/2026-07-atps-recycling-cheaper-pathways-drug.html Biochemistry Thu, 30 Jul 2026 17:00:08 EDT news704642281 The Hiroshima blast on Aug. 6, 1945, was one of the most devastating events in human history. Like all nuclear detonations, it created fleeting moments of extreme heat, pressure, mixing and cooling. These conditions can briefly produce materials that could never form under normal circumstances. https://phys.org/news/2026-07-hiroshima-blast-debris-reveals-previously.html Analytical Chemistry Thu, 30 Jul 2026 10:40:04 EDT news704623621 The pulp and paper industry, which manufactures everything from tissue paper to cardboard, also generates a significant yet often overlooked byproduct—a complex polymer called lignin. Around 100 million tons of lignin are produced each year. Despite being the largest natural source of aromatic carbon on the planet, most of it is burned for energy. This is due to its complex structure, which is notoriously difficult to process. Researchers are exploring ways to leverage industrial lignin by developing methods to convert it into useful bio-based chemicals. https://phys.org/news/2026-07-industry-toughest-lignin-byproducts-feedstock.html Biochemistry Wed, 29 Jul 2026 18:40:03 EDT news704553481 Over the past few decades, scientists have become increasingly interested in developing materials that do not simply withstand mechanical forces but instead respond to them in useful, detectable ways. For example, it is now possible to engineer materials that signal when they are under stress through changes in color or brightness. This growing domain, sometimes called mechanochromic or mechanoresponsive materials science, has found applications in structural sensors and advanced optical technology. https://phys.org/news/2026-07-mechanically-tunable-molecular-circularly-polarized.html Materials Science Wed, 29 Jul 2026 17:20:05 EDT news704550570 The chemical synthesis of oligonucleotides (ONs) is central to modern molecular biology, diagnostics and nucleic acid therapeutics. While demand for high-quality ONs is increasing, the conventional synthetic method has long-standing efficiency challenges. Widely adopted P(III)-phosphoramidite-based ON synthesis requires an oxidation step after every nucleotide coupling cycle and uses moisture-sensitive building blocks, adding complexity to the workflow and slowing the process. https://phys.org/news/2026-07-stable-dna-blocks-enable-faster.html Biochemistry Wed, 29 Jul 2026 16:20:06 EDT news704550121 Plants need nitrogen fertilizers, which are usually ammonia-based.

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. https://phys.org/news/2026-07-local-asymmetry-proton-molecules-simulations.html Analytical Chemistry Mon, 27 Jul 2026 20:40:04 EDT news704385621 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.
