A magnetically actuated acoustic metamaterial
Space coiling acoustic metamaterials are static and require manual reconfiguration for sound-field modulation. In a new report published in Communications Materials, Christabel Choi, and a team of scientists in computer science and engineering in the.....»»
New study shows that word-initial consonants are systematically lengthened across diverse languages
Speech consists of a continuous stream of acoustic signals, yet humans can segment words from each other with astonishing precision and speed. To find out how this is possible, a team of linguists has analyzed durations of consonants at different pos.....»»
Sound drives "quantum jumps" between electron orbits
Cornell University researchers have demonstrated that acoustic sound waves can be used to control the motion of an electron as it orbits a lattice defect in a diamond, a technique that can potentially improve the sensitivity of quantum sensors and be.....»»
Research shows the ocean is becoming too loud for oysters
Baby oysters rely on natural acoustic cues to settle in specific environments, but new research from the University of Adelaide reveals that noise from human activity is interfering with this critical process......»»
Researchers develop novel procedure for isolating primary mouse hepatocytes with holographic acoustic tweezers
Recently, a research team established a comprehensive procedure for isolating primary mouse hepatocytes and maintaining them in long-term culture with significant amplification in a two-dimensional (2D) environment. The team was led by Prof. Li Fei a.....»»
Q&A: "We lost instruments chewed or crunched by bears and sea otters"—how a researcher listens for elusive belugas
Dr. Manuel Castellote studies the behavior and conservation of whales and dolphins. After beginning his academic career in Spain, he now works in the United States, applying acoustic techniques to learn more about cetaceans—especially beluga whales.....»»
Observation of 3D acoustic quantum Hall states
The quantum Hall effect (QHE) is one of the most notable discoveries in condensed matter physics, opening the door to topological physics. Extending QHE into three dimensions is an inspiring but challenging endeavor. This difficulty arises because th.....»»
Artificial nanomagnets inspire mechanical system with memory capability
An international research team including Los Alamos National Laboratory and Tel Aviv University has developed a unique, mechanical metamaterial that, like a computer following instructions, can remember the order of actions performed on it. Named Cha.....»»
A spider silk sound system: Webs match acoustic particle velocity for long-distance sound detection
The best microphone in the world might have an unexpected source: spider silk. Spiders weave webs to trap their insect snacks, but the sticky strands also help spiders hear......»»
New surface acoustic wave techniques could lead to surfing a quantum internet
Researchers at the University of Rochester have used surface acoustic waves to overcome a significant obstacle in the quest to realize a quantum internet......»»
Artificial intelligence enhances monitoring of threatened marbled murrelet
Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species, research by Oregon State University and the U.S. Forest Service ha.....»»
Report suggests Switch 2 can play all original Switch games
New Joy-con buttons, 1080p screen also feature in MobaPad's "first-hand information." A mock-up posted by MobaPad provides one vision of how magnetically attached Switch 2 Joy-Cons might look (credit: MobaPad) Thus far,.....»»

Team demonstrates an ultra-broadband tunable terahertz absorber of graphene and hierarchical plasmonic metamaterials
Perfect absorption arises from the strong interaction of valence electrons with light in a conducting material. Optical metamaterial is an effective approach to exploit the superior photon capture capability. Thus, the perfect absorbers could be achi.....»»
Caller ID of the sea: Novel method of simultaneous acoustic tagging provides insight into whale communication
For researchers studying the acoustic behavior of whales, distinguishing which animal is vocalizing is like a teacher trying to figure out which student responded first when the entire class is calling out the answer. This is because many of the tech.....»»
Research team proposes a novel type of acoustic crystal with smooth, continuous changes in elastic properties
In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye that is not focused by the.....»»
Experts urge dog owners to teach life skills to help their canines cope with distractions
Many working dogs have to cope with sirens, sudden loud noises and flashing lights while carrying out vital work that keeps humans safe. Visual and acoustic distractions distinctly affect people's ability to concentrate and perform tasks; a new study.....»»
Good prospects for altermagnets in spin-based electronics
Altermagnets represent a newly recognized class of materials in magnetism that could enable novel applications in spin-based electronics. Their magnetically ordered state consists of an antiparallel arrangement of microscopic magnetic moments, so-cal.....»»
Acoustic invention enhances ultrasound to access enclosed metal spaces
The inside of underwater pipes and enclosed nuclear containers were inaccessible—until recently. Acoustics researchers in Penn State's College of Engineering have developed a way to convey energy and transmit communications through metal walls usin.....»»
A new optical metamaterial makes true one-way glass possible
A new approach has allowed researchers at Aalto University to create a kind of metamaterial that has so far been beyond the reach of existing technologies. Unlike natural materials, metamaterials and metasurfaces can be tailored to have specific elec.....»»
Aerosol jet printing could revolutionize microfluidic device fabrication
Surface acoustic wave (SAW) technologies, known for their high precision and rapid actuation, are essential to microfluidics and affect a broad spectrum of research areas. However, traditional fabrication methods are time-consuming, intricate, and ne.....»»
