Omega-3 fatty acids are known to be an essential part of a healthy diet. As humans cannot produce them, they have to be consumed in sufficient amounts. However, omega-6, -7, -9, and -10 fatty acids also play important roles in the metabolism of fats. These numbers indicate the position of the first double bond in a fatty acid chain. Deviations in the omega position can signal enzyme malfunctions or pathological metabolic processes, such as those occurring in cancer. Now, researchers at the University of Graz and the University of California, San Diego present in Nature Communications a novel, effective method to determine omega positions of lipids – the scientific term for fats – in complex biological samples including human tissues and blood.

How can quantum technologies be developed responsibly? In the journal Science, researchers from the Technical University of Munich (TUM), the University of Cambridge, Harvard University and Stanford University argue that international standards should be established before laws are enacted. Prof. Urs Gasser explains why the authors propose a quality management system for quantum technologies, how standards create trust and where even competing countries such as China and the US can cooperate.

A Japanese superconducting quantum computer, designed and built with homegrown components and software, went live on July 28th at The University of Osaka’s Center for Quantum Information and Quantum Biology (QIQB). This achievement signifies Japan's technological prowess in quantum computing, demonstrating the nation's capacity to design, manufacture, and integrate a complete quantum system. Visitors to Expo 2025, Osaka, Kansai, Japan will have the opportunity to interact with this cutting-edge technology through a dedicated exhibit.

A machine learning method developed by researchers from Institute of Science Tokyo, the Institute of Statistical Mathematics, and other institutions accurately predicts liquid crystallinity of polymers with 96% accuracy. They screened over 115,000 polyimides and selected six candidates with a high probability of exhibiting liquid crystallinity. Upon successful synthesis and experimental analyses, these liquid crystalline polyimides demonstrated thermal conductivities up to 1.26 W m⁻¹ K⁻¹, accelerating the discovery of efficient thermal materials for next-generation electronics.

What happens when things combine? This question lies at the heart of the Borell-Brascamp-Lieb inequality (BBL), a mathematical relation widely applied across many fields of mathematics, science and beyond. Now, researchers from the Okinawa Institute of Science and Technology (OIST), University of Tokyo and University of Florence have provided a new proof for this powerful inequality, taking an unconventional approach based on heat and diffusion equations.
