2+ hour, 31+ min ago (611+ words) Inspired by advances in artificial intelligence, researchers have developed a new type of neural network that more accurately identifies and quantifies peaks in complex molecular spectra, offering an eleven percent improvement in accuracy and a thirty percent reduction in error compared to conventional methods. https://quantumzeitgeist.com/wp-content/uploads/Capture-723.jpg Identifying and quantifying peaks within complex spectra, such as those generated by Nuclear Magnetic Resonance, presents a significant challenge for scientists, particularly when analysing intricate molecules. Lukas Bischof, Rudolf M. F'chslin, Kurt Stockinger, and Pavel Sulimov, all from Zurich University of Applied Sciences, now demonstrate a powerful new approach to this problem using Quanvolutional Neural Networks. Inspired by the success of conventional Convolutional Neural Networks, their research introduces a novel architecture that excels at both counting peaks and accurately determining their positions within a spectrum. The team's results reveal that these Quanvolutional Neural Networks outperform their…...

3+ hour, 59+ min ago (819+ words) Researchers have created a system, QFANG, that automatically generates detailed, step-by-step laboratory procedures directly from chemical equations, significantly improving the potential for fully automated drug discovery and chemical synthesis. https://quantumzeitgeist.com/wp-content/uploads/Capture-715.jpg Automated planning of chemical synthesis remains a significant hurdle in accelerating drug discovery and enabling fully robotic laboratories, largely because translating computational routes into practical, executable procedures proves challenging. Guoqing Liu, Junren Li, and Zihan Zhao, working with colleagues at Microsoft Research and Shanghai Jiao Tong University, now present a new model, QFANG, which directly generates detailed, structured experimental procedures from simple reaction equations. This achievement stems from a novel Chemistry-Guided Reasoning framework and a large dataset of nearly one million chemical reactions, carefully extracted from patent literature, allowing the model to learn complex chemical reasoning. The team further refined QFANG using a reinforcement learning approach, resulting in a system…...

4+ hour, 3+ min ago (582+ words) A group of North Carolina health and science leaders is calling on the Environmental Protection Agency to release a long-awaited toxicity report on PFNA, a "forever chemical" found in drinking water systems in North Carolina and nationwide. The request comes after a ProPublica investigation reported that EPA scientists completed the PFNA toxicity assessment in April and prepared it for public release, citing internal documents and two agency scientists familiar with the report. The assessment has still not been published. In a letter sent last month to Rep. Greg Murphy, R-N.C., researchers from UNC-Chapel Hill, Duke University, East Carolina University and several former EPA officials urged him to press the agency for transparency. The signatories wrote that without access to the findings, "families in North Carolina, and across the country, [cannot] know their water is safe." PFNA, part of the PFAS…...

4+ hour, 52+ min ago (452+ words) Newswise " FAMU-FSU College of Engineering researchers are applying fuel cell technology to new applications like sustainable energy and water treatment. In a study published in Frontiers in Membrane Science and Technology, the researchers examined a type of membrane called a perfluorosulfonic acid polymer membrane, or PFSA polymer membrane. These membranes act as filters, allowing protons to move through, but blocking electrons and gases. In the study, the researchers examined how boiling these membranes " a common treatment applied to the material " affects their performance and helps them work as specialized tools for different applications. During production, PFSA membranes sometimes undergo boiling as pretreatment, which helps them to absorb more water and thereby transport ions faster. The research team showed how pretreatment leads to design tradeoffs: Treated membranes showed increased water absorption, which led to better conductivity (faster transport of desired material…...

5+ hour, 50+ min ago (389+ words) Quantum Zeitgeist is a leading independent news source covering quantum computing breakthroughs, industry developments, and research advances. Established in 2018, we provide daily analysis of quantum technology's impact on computing, cryptography, and scientific innovation. Controlling the direction of solar sails, vast reflective sheets propelled by sunlight, presents a significant challenge for deep-space exploration, as traditional methods often require substantial energy. Gulzhan Aldan and Igor Bargatin, both from the University of Pennsylvania, now demonstrate a novel approach utilising the unique properties of kirigami, the ancient art of paper cutting. Their research reveals that specially perforated and stretched films, when illuminated, redirect light and generate forces parallel to the sail's surface, offering a potential means of steering without conventional propulsion systems. This breakthrough suggests a scalable, lightweight, and crucially, low-power method for controlling solar sails, paving the way for more efficient and ambitious…...

6+ hour, 55+ min ago (1074+ words) Researchers demonstrate that the probability of the universe originating with specific characteristics increases significantly due to resonant effects within a model incorporating radiation, a novel fluid, and a potential energy field. https://quantumzeitgeist.com/wp-content/uploads/Capture-706.jpg The very earliest moments of the universe remain a profound mystery, and new research explores how fundamental properties might have emerged from the initial conditions. D. L. Canedo, G. Oliveira-Neto, G. A. Monerat, and E. V. Corr'a Silva investigate a model of the early universe containing radiation and exotic forms of matter, revealing the possibility of "resonances" within the universe"s potential energy landscape. Their work demonstrates that these resonances, which act as preferred pathways for the universe to emerge, could explain why the universe possesses specific values for certain key parameters. This finding represents a significant step towards understanding the initial conditions that shaped the cosmos, potentially offering insights into the fundamental constants governing…...

7+ hour, 6+ min ago (879+ words) Scientists have discovered a single-celled amoeba that grows at temperatures once thought impossible for complex life, pushing the known limits of eukaryotic survival. (CREDIT: Wikimedia / CC BY-SA 4.0) Scientists had previously assumed that no eukaryotic life could survive temperatures above approximately 60 degrees Celsius; any higher temperature would cause the proteins and membranes necessary for life to break down. However, the discovery of this single-celled organism proves that there is a possible ceiling for the temperature at which eukaryotic life may survive. H. Beryl Rappaport and Angela Oliverio of Syracuse University in New York told The Brighter Side of News, "Our findings challenge long-held temperature limits for eukaryotic cells and expand our view of where this kind of life can survive." The organism was isolated from geothermal springs found in tributaries of Hot Springs Creek, located in Northern California. The research team conducted…...

11+ hour, 10+ min ago (863+ words) Water looks familiar in a glass, yet it behaves very differently when pushed to extremes. When researchers in Manchester squeezed water into ultra-thin channels inside crystals, it carried electric current up to 100,000 times better than ordinary water. This discovery is important because many of nature's crucial processes occur in areas where water touches a surface, not deep in the liquid." Changing how easily charges move in those tiny regions could reshape how we understand chemistry inside cells and inside advanced materials. In everyday conditions, water molecules hook together through a hydrogen bond network, a shifting web of weak attractions between neighboring molecules." This network helps water dissolve salts, stabilizes proteins, and already gives bulk water a surprisingly high ability to let electric charges move. The work was led by Laura Fumagalli, a physicist at the University of Manchester who specializes…...
