A new method provides a more realistic description of loads on large-scale wind turbines than was previously possible: A German research team has developed a more accurate mathematical model of wind fluctuations across the rotor surface. This allows for a better capture of sudden, localized gusts of wind. These localized loads are a key factor in premature material fatigue, especially in larger wind turbines.

Floatable beads made from chitosan and cellulose acetate and enhanced with bentonite were engineered to effectively clean oil from water. The beads showed good oil adsorption capacity while remaining easy to collect from the water surface. 

What culinary practices prevailed in the South Caucasus during the Bronze Age? The cuisine was remarkably diverse. This is what an international research team from the Universities of Bonn and Bari, along with other scientific institutions such as the Centre National de la Recherche Scientifique (CNRS) and the Azerbaijan National Academy of Sciences report. The new evidence highlights a multi-ingredient cuisine alongside the central role of dairy products, fruit, and grape-based beverages in Kura-Araxes communities. The findings have now been published in the journal PNAS. 

Kyoto, Japan -- A team of researchers at Kyoto University have demonstrated that the chaotic component of heartbeat variability is uniquely sensitive to cognitive brain activity. Conventional hear rate variability, HRV, indices show no consistent response, whereas chaos-based measures reveal clear and reproducible changes, providing a new non-invasive indicator of brain-heart interaction.

HRV is widely used as an indicator of autonomic nervous system function. However, its ability to reflect higher-order brain activity has remained unclear. In this study, the researchers applied nonlinear analysis and chaos theory to examine heartbeat dynamics under cognitive load.

The researchers had participants perform cognitive tasks designed to engage higher-order brain functions. They then analyzed heartbeat signals using both conventional HRV indices -- such as time-domain and frequency-domain measures -- and chaos-based metrics derived from nonlinear dynamics.

Wireless signals do not travel well through the human body, especially in high-frequency bands, such as the UWB band, making it difficult for swallowable medical devices to reliably send data outside the body. By accounting for how different frequencies behave in the body, researchers adjusted each part of the signal to match how it is absorbed and distorted by tissue, creating a stronger, clearer signal at the receiver.  

Nanyang Technological University, Singapore (NTU Singapore) will house the first two Max Planck Centres in Southeast Asia, the Max Planck – Singapore Centre for Data-Driven Chemistry and the Max Planck – NTU Singapore Centre for Biocultural Worlding.

 

These centres are flagship collaborative research initiatives between the Max Planck Society (MPG) in Germany and leading international research institutions. They serve as hubs of scientific excellence, bringing together top researchers from around the world to address frontier questions across diverse disciplines.

 

The Max Planck – Singapore Centre for Data Driven Chemistry aims to study how the complex volume of chemical research data can be digitalised and analysed effectively to better understand chemical processes and shed light on new reactions.

 

The Max Planck – NTU Singapore Centre for Biocultural Worlding will study how the close connection between nature and human cultures shape the future of our planet, and what kinds of knowledge and approaches are needed to respond effectively.

Antimicrobial resistance is becoming a global burden in human health and food production, so affordable new materials are needed to overcome this growing problem.

To answer the call, a multidisciplinary research team led by Flinders University with UK experts has discovered a novel solution for safe and effective use in antimicrobial and antifungal applications.
