Engineers developed a training method for multiagent systems, such as large numbers of drones, that can guarantee their safe operation in crowded environments.

Researchers have explored how integrating machine and deep learning techniques can create a standardized system for evaluating rock climbing routes to provide a difficulty grading scale that promotes inclusivity, accuracy and accessibility for all experience levels. The study found that the most successful approach for determining the difficulty of a rock-climbing route used route-centric, natural language processing methods.

A recent study by management scholars underscores the importance of organizations' dynamic capabilities for greener business practices. Analyzing data from 139 manufacturing companies, the research reveals that financial and technological expertise combined with adaptability to regulations and evolving consumer demands, are key to advancing the green transition.

Early detection of earthquakes could be vastly improved by tapping into the world's internet network with a groundbreaking new algorithm, researchers say. Fiber optic cables used for cable television, telephone systems and the global web matrix now have the potential to help measure seismic rumblings thanks to recent technological advances, but harnessing this breakthrough has proved problematic. A new paper seeks to address these challenges by adapting a simple physics-based algorithm to include fiber optic data that can then be used hand-in-hand with traditional seismometer measurements.

Chemists have found a new way to determine 3D genome structures, using generative AI, that can predict thousands of genome structures in minutes, making it much speedier than existing methods for analyzing the structures.

Researchers compared the environmental impacts of lithium-ion battery recycling to mining for new materials and found that recycling significantly outperforms mining in terms of greenhouse gas emissions, water use, and energy use.

A new study of satellite imagery and high-resolution climate model data upends previous assumptions and provides insight about how the atmosphere and ocean weather patterns interact. The new research reveals the surprising ways atmospheric winds influence ocean eddies, shaping the ocean's weather patterns in more complex ways than previously believed.

A carnation-like nanostructure could someday be used in bandages to promote wound healing. Researchers report that laboratory tests of their nanoflower-coated dressings demonstrate antibiotic, anti-inflammatory and biocompatible properties. They say these results show these tannic acid and copper(II) phosphate sprouted nanoflower bandages are promising candidates for treating infections and inflammatory conditions.

A team of scientists has made the first experimental measurements of laser-induced motions of miniature lightsails in the lab.

A study assessed the impact of electric fans on the body core temperature and heart rate of 18 participants aged 65-85 years, who were exposed to a simulated extreme indoor environment of 36 degrees Celsius with 45 percent relative humidity for eight hours. The results showed participants were unaffected by fan use, with all three of the experimental conditions resulting in an average body core temperature of 38.3 C and heart rate of 100 beats per minute.

It's been known for some time that radiation impacts the structural integrity of concrete. However, until now the details of this were unknown. Researchers can finally demonstrate what properties of concrete affect its structural characteristics under different neutron radiation loads. Their findings raise some concerns whilst reducing others; for example, quartz crystals in concrete can heal themselves, potentially allowing some reactors to run for longer than initially thought possible.

Researchers measured very precisely atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The discovery provides essential data for understanding how elements heavier than iron are produced in the Cosmos and triggers new research to elucidate the underlying nuclear structure causing this unexpected change in nuclear binding energies.

Researchers are breaking limits by increasing the temperature multiferroics can operate at, from room temperature up to a blistering 160 degrees Celsius.

The development of vehicle components is a lengthy and therefore very costly process. Researchers have developed a method that can shorten the development phase of the powertrain of battery electric vehicles by several months. A team is combining simulation models of components with evolutionary optimization algorithms. This AI system automatically optimizes the entire powertrain -- from the power electronics to the electric machine through to the transmission -- in line with the manufacturer's technical requirements, taking into account targets such as production costs, efficiency and package space requirements in the vehicle.

Skyrmions are nanometer- to micrometer-sized magnetic whirls that exhibit particle-like properties and can be moved efficiently by electrical currents. These properties make skyrmions an excellent system for new types of data storage or computers. However, for the optimization of such devices, it is usually too computationally expensive to simulate the complicated internal structure of the skyrmions. One possible approach is the efficient simulation of these magnetic spin structures as particles, similar to the simulation of molecules in biophysics. Until now, however, there has been no conversion between simulation time and experimental real time.

Researchers have demonstrated a new, unsupervised machine learning approach to find new patterns in the auxiliary channel data of the Laser Interferometer Gravitational-Wave Observatory.

By using optically active liquid crystals as reaction sites, researchers have successfully achieved the living polymerization of polymers with aligned helical structures. In this process, optically inactive monomers adopt the chiral (mirror-image) structure in liquid crystals as they grow, resulting in optically active polymers. This breakthrough represents a pioneering achievement in both asymmetric chemistry and polymer chemistry.

Researchers have developed a new material that harnesses the power of enzymes more effectively. These materials have improved the reaction efficiency and long-term stability of enzymes in electrochemical biosensors used in health care and other applications. Furthermore, the researchers significantly enhanced device performance.

The electronics of the future can be made even smaller and more efficient by getting more memory cells to fit in less space. One way to achieve this is by adding the noble gas xenon when manufacturing digital memories. This technology enables a more even material coating even in small cavities.

A research group has developed new advanced light-controlled tools that enable precise control of proteins in real time in living cells. This groundbreaking research opens doors to new methods for studying complex processes in cells and could pave the way for significant advances in medicine and synthetic biology.
