There is more than one way to describe a water molecule, especially when communicating with a machine learning (ML) model, says chemist Robert DiStasio. You can feed the algorithm the molecule's structural information: two hydrogen atoms flanking an oxygen atom with the bonds a certain length and a certain bond angle. https://phys.org/news/2025-12-quantum-mechanical-molecular-fingerprints-machine.html Biochemistry Wed, 17 Dec 2025 12:50:06 EST news685197774 Sometimes, less really is more. By removing oxygen during synthesis, a team led by materials scientists at Penn State has created seven new high-entropy oxides (HEOS), a class of ceramics composed of five or more metals with potential for applications in energy storage, electronics and protective coatings. https://phys.org/news/2025-10-simple-stabilizing-solution-ceramic-materials.html Analytical Chemistry Mon, 20 Oct 2025 16:38:03 EDT news680197081 Aluminum oxide or alumina is the fruit fly of materials science: thoroughly researched and well-understood. This compound, with the simple chemical formula Al2O3, occurs frequently in Earth's crust in the form of the mineral corundum and its well-known color variants sapphires and rubies—and is used for a wide variety of purposes, whether in electronics, the chemical industry, or technical ceramics. https://phys.org/news/2025-08-machine-reveals-mysteries-amorphous-alumina.html Analytical Chemistry Wed, 13 Aug 2025 13:13:03 EDT news674309581 A team of researchers from Ca' Foscari University of Venice and the Universidad Autónoma de Madrid has developed a groundbreaking technique that maps temperature in three dimensions within biological tissue, using invisible light and artificial intelligence. https://phys.org/news/2025-07-scientists-3d-temperature-tissue-ai.html Cell & Microbiology Wed, 16 Jul 2025 09:42:58 EDT news671877773 Researchers at Kanazawa University report in Angewandte Chemie International Edition how the formation and deformation speed of interlocked molecular structures called rotaxanes can be tuned—a discovery that may lead to an enhanced functionality of rotaxanes as building blocks for molecular machines. https://phys.org/news/2023-02-molecular-demand.html Analytical Chemistry Fri, 24 Feb 2023 10:50:03 EST news596458201 Hair loss is undesirable for many men—and women—because one's hairstyle is often closely tied to their self-confidence. And while some people embrace it, others wish they could regrow their lost strands. Now, researchers reporting in Nano Letters have used artificial intelligence (AI) to predict compounds that could neutralize baldness-causing reactive oxygen species in the scalp. Using the best candidate, they constructed a proof-of-concept microneedle patch and effectively regenerated hair on mice. https://phys.org/news/2022-10-ai-microneedle-patches-hair-balding.html Bio & Medicine Mon, 31 Oct 2022 14:20:50 EDT news586444848 A new class of motorized molecules that kill specific bacteria shows promise to curb the threat of antibiotic resistance to human health. https://phys.org/news/2022-08-lightactivated-molecular-machines-antibiotic-resistance.html Biochemistry Thu, 25 Aug 2022 17:00:04 EDT news580665601 Ancient microbes may have been producing oxygen through photosynthesis a billion years earlier than we thought, which means oxygen was available for living organisms very close to the origin of life on earth. In a new article in Heliyon, a researcher from Imperial College London studied the molecular machines responsible for photosynthesis and found the process may have evolved as long as 3.6 billion years ago. https://phys.org/news/2018-03-photosynthesis-billion-years-earlier-thought.html Earth Sciences Tue, 06 Mar 2018 12:21:18 EST news439561264
