Liquid water molecules are inherently asymmetric. Icebergs float on liquid water, 4°C cold water sinks to the bottom: With its anomalies, water still poses a number of scientific puzzles. Researchers led by Johannes Hunger at the Max Planck Institute for Polymer Research have investigated the bonds between a water molecule and its neighbors in the liquid phase. They have discovered that the distances to neighboring molecules are not just randomly distributed: The two hydrogen atoms of a water molecule form…

… for laser inertial fusion for the clean energy supply of the future. In order for future laser fusion power plants to work efficiently and reliably, current laser technologies must be adapted to the extreme requirements of high power and continuous operation. In the new “nanoAR” research project, nine project partners from industry and research are working on methods for structural antireflection solutions and reducing sub-surface damage of the optical components used. Their approaches could also be transferred to other…
Kumamoto University scientists have unveiled a novel compound, HPH-15, with dual effects of reducing blood glucose levels and combating fat accumulation, marking a significant leap in diabetes treatment innovation. Type 2 diabetes, a condition affecting millions worldwide, is often accompanied by complications like fatty liver and insulin resistance, which challenge current treatment methods. The research team, led by Visiting Associate Professor Hiroshi Tateishi and Professor Eiichi Araki, has identified HPH-15 as a promising alternative to existing medications like metformin. The…
Speed and precision unlocked… A novel computational technique offers a faster, more accurate approach for measuring bioactive carotenoids, reducing error rates and analysis time. Carotenoids, the pigments responsible for the vibrant hues of tomatoes, carrots, and some seafood, are well-regarded for their antioxidant effects and health benefits. A few examples of commercially significant carotenoids are lycopene, β-carotene, and astaxanthin. These compounds are frequently used in functional foods, skincare products, and dietary supplements. However, the bioactivity of these carotenoids depends heavily…
Researchers from Singapore and China have used a superconducting quantum processor to study the phenomenon of quantum transport in unprecedented detail. A better understanding of quantum transport, which can refer to the flow of particles, magnetisation, energy or information through a quantum channel, could propel advances in technologies such as nanoelectronics and thermal management. “We’re quite excited because this is, practically, a new paradigm of doing quantum transport experiments,” says Centre for Quantum Technologies (CQT) Fellow Dario Poletti, whose co-corresponding…
Scientists at the University of Würzburg and the German national metrology institute (PTB) have carried out an experiment that realizes a new kind of quantum standard of resistance. It’s based on the Quantum Anomalous Hall Effect. The precise measurement of electrical resistance is essential in industrial production or electronics – for example, in the manufacture of high-tech sensors, microchips and flight controls. “Very precise measurements are essential here, as even the smallest deviations can significantly affect these complex systems”, explains…
Glyphosate exposure exacerbates Alzheimer’s disease-like pathology in mice even after a significant pause from exposure. The human brain is an incredibly adaptable organ, often able to heal itself even from significant trauma. Yet for the first time, new research shows even brief contact with a common herbicide can cause lasting damage to the brain, which may persist long after direct exposure ends. In a groundbreaking new study, Arizona State University researcher Ramon Velazquez and his colleagues at the Translational Genomics Research Institute…
With a novel approach, EMBL scientists discovered important interactions between molecular machines, potentially offering new opportunities for drug development. Choosing a film for a movie night is always a battle. Now imagine if you could pick one that provided a window into some of the most fundamental biological processes that keep us alive. For the first time ever, researchers have captured a real-time molecular movie to show how two essential cellular processes – transcription and translation – interact with each…
A team of researchers has beaten its own record for the fastest swimming soft robot, drawing inspiration from manta rays to improve their ability to control the robot’s movement in the water. “Two years ago, we demonstrated an aquatic soft robot that was able to reach average speeds of 3.74 body lengths per second,” says Jie Yin, corresponding author of a paper on the work and an associate professor of mechanical and aerospace engineering at North Carolina State University. “We…
Caltech’s algorithm called Spectral Expansion Tree Search helps autonomous robotic systems make optimal choices on the move. In 2018, Google DeepMind’s AlphaZero program taught itself the games of chess, shogi, and Go using machine learning and a special algorithm to determine the best moves to win a game within a defined grid. Now, a team of Caltech researchers has developed an analogous algorithm for autonomous robots—a planning and decision-making control system that helps freely moving robots determine the best movements…
An international team of researchers including The University of Tokyo Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) has found evidence showing that old elliptical galaxies in the universe can form from intense star formation within early galaxy cores. This discovery will deepen our understanding of how galaxies evolved from the early Universe, reports a new study in Nature. Galaxies in today’s Universe are diverse in morphologies and can be roughly divided into two categories:…
Researchers propose a simple fix to an existing technique that could help artists, designers, and engineers create better 3D models. Creating realistic 3D models for applications like virtual reality, filmmaking, and engineering design can be a cumbersome process requiring lots of manual trial and error. While generative artificial intelligence models for images can streamline artistic processes by enabling creators to produce lifelike 2D images from text prompts, these models are not designed to generate 3D shapes. To bridge the gap,…
What was the cause of the great Tōhoku earthquake of 2011, and how can we better understand geological processes in order to protect coastal infrastructure in the long term – for example, from a tsunami like the one 13 years ago? These questions are currently the focus of a scientific expedition as part of the International Ocean Discovery Program (IODP), in which researchers from the MARUM – Center for Marine Environmental Sciences at the University of Bremen are participating. Since…
– climate change causes more sediment in high-mountain rivers. Many high-mountain rivers in Asia transport more sediment downstream compared to a few years ago. Changes in sediment levels have a particularly strong impact on agriculture, water quality, flood management, and hydropower generation. A study with participation of the University of Potsdam demonstrates the interacting roles of glaciers, vegetation, precipitation, and slope in mobilizing sediment and controlling the current sediment transport in rivers. In order to counteract climate change, the authors…
Researchers at the Leibniz Institute of Vegetable and Ornamental Crops (IGZ) investigated the seasonal variation in glucosinolates and their enzymatic hydrolysis products in red and white cabbage, as well as broccoli. The results provide crucial insights for cultivating and utilizing these vegetables for healthy diets and functional food production. The study was carried out on the IGZ experimental fields in Großbeeren in three consecutive years from 2020 to 2022. It revealed that red cabbage shows significant variation in the amounts…
