New fishing management tools for the Pyrenean marine coastline
The Pyrenean marine coastline has a high biological connectivity between fish populations that move around different habitats at a regional scale, according to the RESMED project (2019–2021), an initiative based on acoustic telemetry techniques for.....»»
Topological materials become switchable
A donut is not a breakfast roll. Those are two very clearly distinguishable objects: One has a hole, the other does not. In mathematics, the two shapes are said to be topologically different—you cannot transform one into the other by small, continu.....»»
RF BAW filter maker Akoustis builds Asia-Pacific foothold in Taiwan
Akoustis Technologies, a US-based IDM of bulk acoustic wave (BAW) high-band filters for mobile and other wireless applications, has located its Asia-Pacific foothold in Taoyuan, northern Taiwan, looking to better serve Taiwanese ODMs and explore more.....»»
Spiral dislocation gives 3D topological photonics a robust edge
Crystals have enthralled humans for thousands of years with their visual beauty and elegant symmetrical shapes, and, more recently, with their numerous technological applications. Fundamentally, these materials are based on a highly regular arrangeme.....»»

Humpback whale songs spread from pod to pod across the Pacific Ocean
A team of researchers with members from the University of St Andrews, Universidad San Francisco de Quito and the CETACEA Ecuador Project's Acoustic Ecology Program has found that songs created by humpback whales in some parts of the Pacific Ocean are.....»»
New insights into the interaction of topological insulators
Tungsten di-telluride (WTe2) has recently proven to be a promising material for the realization of topological states. These are regarded as the key to novel "spintronic" devices and quantum computers of the future due to their unique electronic prop.....»»
Researchers find novel topology-correlation interplay in toy model system built from iridate superlattice
In topological physics, band topology often originates from spin-orbit interaction, which gives rise to complex hopping parameters. While this approach has enjoyed great success in non-interacting or weakly interacting electronic materials, the conse.....»»
Saturn V was loud but didn"t melt concrete
The Saturn V carried man to the moon and remains the most powerful rocket to successfully launch to orbit. It captures the imagination—but sometimes, it might capture a bit too much imagination. Abundant internet claims about the acoustic power of.....»»
Asian elephants have a nasal pronunciation
With the help of an acoustic camera that visualizes sound pressure, researchers from the University of Vienna investigated the calls of Asian elephants. The elephants emitted their low frequency "rumbles" mainly through their trunk or through their m.....»»
