49+ min ago (833+ words) Researchers successfully used a quantum computer to predict how water molecules bind to proteins, matching the accuracy of conventional methods and suggesting a path towards improved drug discovery simulations with more powerful quantum hardware. https://quantumzeitgeist.com/wp-content/uploads/Image_fx-6-11.jpg Predicting how water molecules interact within protein pockets represents a critical challenge in drug discovery, influencing how effectively potential medications bind to target proteins. Daniele Loco from Qubit Pharmaceuticals, Kisa Barkemeyer and Andre R. R. Carvalho from Q-CTRL, along with Jean-Philip Piquemal from Sorbonne Universit "e, now demonstrate a practical approach to this problem using a quantum computer. The team successfully predicts hydration sites within protein pockets, matching the precision of established classical methods, and achieves this using hardware experiments involving up to 123 qubits. This work represents a significant step towards realising the potential of noisy intermediate-scale quantum computers for real-world applications in drug development, and suggests…...

However, the widespread adoption of water electrolyzers has encountered a formidable obstacle: the presence of impurities, particularly chloride ions, in low-grade water sources. These chloride impurities have long been notorious for undermining the selectivity and operational longevity of electrochemical water splitting devices, fostering side reactions that erode efficiency and durability. But a groundbreaking study now illuminates a promising pathway to circumvent this challenge, offering a…...

3+ hour, 15+ min ago (349+ words) Scottish scientists plan to send a small sample of fabric into space to test a special dye which can detect radiation. Fabrics painted with specially-designed dyes made from different types of bacteria will be launched from one of SpaceX's Falcon 9 rockets in February next year. The sample will be aboard a tiny satellite called a PocketQube, which will help to test the dye's performance in space. It is hoped this dye could be used in missions to the moon or other forms of space exploration as a passive radiation detector. It could also be used on Earth to monitor exposure to sunlight or radiation in clinical settings. Dr Gilles Bailet, a lecturer in space technology at the University of Glasgow, is leading the "Pigmented Space Pioneers" project. He said: "Exposure to radiation breaks up the pigments in the bacteria, while…...

5+ hour, 21+ min ago (683+ words) At a steaming creek in California's Lassen Volcanic National Park, a tiny amoeba just raised the heat ceiling for complex cells." A Syracuse University team reports that the single-celled eukaryote divided at about 145 degrees Fahrenheit. For decades, the accepted upper limit for such organisms sat near 140 degrees Fahrenheit." The work was led by Beryl Rappaport, a microbiologist completing her PhD at Syracuse University. Her research focuses on heat tolerant eukaryotic microbes in volcanic hot spring systems. She and colleagues sampled a tributary of Hot Springs Creek near Boiling Springs Lake, a hydrothermal basin in the park." The nearby lake stays at about 125 degrees Fahrenheit year-round. The new organism sits within Amoebozoa, a broad group of amoebae with flexible cell shapes. It moves and feeds with temporary extensions that let it glide over mineral rich films. "Eukaryotes can grow at higher…...

5+ hour, 44+ min ago (720+ words) Per-and polyfluoroalkyl substances (PFAS), long lasting human-made chemicals built from carbon and fluorine, are now used in thousands of everyday products." Scientists worry because many of these compounds stay in water, soil, and human blood for years. A group of 20 scientists says some industry-linked voices are trying to shrink that definition so fewer PFAS show up on official lists." They argue that this is not just a technical debate but a political move that could roll back protections for people and ecosystems. The work was led by Gabriel Sigmund, an environmental technology researcher at Wageningen University in the Netherlands." His research focuses on how long lived industrial chemicals move through water, soil, and living organisms. Large human studies have found that some PFAS in drinking water and blood are linked to higher cholesterol and weaker vaccine response." Researchers have also…...

5+ hour, 45+ min ago (813+ words) By optimising connectivity, expansion order, and molecular orbital basis, researchers have significantly improved the efficiency of a quantum algorithm for simulating molecules, and surprisingly discovered that noise from a real quantum computer can, in some cases, enhance the accuracy of the results. https://quantumzeitgeist.com/wp-content/uploads/Image_fx-22-10.jpg The challenge of simulating complex molecular systems represents a major hurdle in materials science and quantum chemistry, and researchers continually seek more efficient computational methods. L. Andrew Wray, Cheng-Ju Lin, and Vincent Su, alongside Hrant Gharibyan from BlueQubit Inc., investigated improvements to a technique called sample-based diagonalization, a hybrid quantum-classical algorithm designed for use on emerging quantum computers. Their work focuses on optimising this method for modelling cuprate chains, materials crucial to understanding high-temperature superconductivity, and reveals that enhanced connectivity, higher-order expansions, and alternative molecular orbital bases significantly improve computational convergence. Notably, the team discovered that even the…...
