The first FitzHugh-Nagumo neuron circuit designed to include noise and exhibit the Ghost Stochastic Resonance effect has been presented by researchers from Université de Bourgogne in France. Their circuit operates according to the exact expression of the nonlinearity required by the FitzHugh-Nagumo model of neural activity. This has allowed them to investigate the real-time effect of noise and confirm that a ghost frequency is present, a nonlinear signature that could be useful to develop pitch perception applications.
One hand clinging to his boat's gunwale, Harun Muhammad submerges himself, eyes and ears wide open underwater as he "listens" for fish sounds emanating from the blue depths.
Researchers have given a sweeping assessment to understand how human activities are affecting estuaries, the nation's sounds, bays, gulfs and bayous. This first comprehensive look at changes in land cover, river flow, pollution and nutrient levels offers a comprehensive look at the state of America's estuaries.
The singer-songwriter tweeted with astronaut Reid Wiseman during a visit to the Space Center in Florida. He was there to promote his new song, "American Flag on the Moon".
Many people listen to loud music without realizing that this can affect their hearing. This could lead to difficulties in understanding speech during age-related hearing loss which affects up to half of people over the age of 65. New research has examined the cellular mechanisms that underlie hearing loss and tinnitus triggered by exposure to loud sound.
An optical frequency comb that has record low laser relative intensity noise and in which the carrier envelope offset frequency has been stabilised to very low level, has been demonstrated by researchers at Centre Suisse d'Electronique et de Microtechnique (CSEM) in Switzerland.
You don't have to listen to heavy-metal music to be a metal head. The human brain harbors far more copper, iron and zinc than anywhere else in the body. Abnormally high levels of these metals can lead to disorders such as Alzheimer's and Parkinson's diseases. Chris Chang, a faculty chemist with Berkeley Lab's Chemical Sciences Division, has spent the past several years developing new probes and techniques for imaging the molecular activity of these metals in the brain. Speaking at the national meeting of the American Chemical Society (ACS) in San Francisco, he discussed challenges and recent achievements in this area of research.
The U.S. Air Force Research Laboratory is studying hypersonic vehicles that would use the Synergetic Air-Breathing Rocket Engine (SABRE), which is intended to power the Skylon space plane, AFRL officials said.
(Michigan State University) In this week's edition of Estuaries and Coasts, a Michigan State University doctoral student joins with others to give a sweeping assessment to understand how human activities are affecting estuaries, the nation's sounds, bays, gulfs and bayous.
Country music star Brad Paisley traveled to NASA's Kennedy Space Center in Florida to launch his new song, 'American Flag on the Moon.' 'I'm at NASA's Apollo launch pad in FL, leaking my new song,' Paisley wrote on Twitter.
It sounds like science fiction, but it seems that bacteria within us -- which outnumber our own cells about 100-fold -- may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity.
Companies have been cleared to seek seismic noise permits in the Atlantic, but ocean researchers fear for whales.
An enterprising team with experience in music, engineering, coding, product and graphic design, have come up with a prototype called LightFreq, This is a Bluetooth light bulb with built-in HD audio. A light bulb and speaker combo? Why would anyone want to own that kind of device? The team has an engaging set of answers: "Why do we only use our lights to see? That would be like only using our phones to make calls, right?" "We solved the problem of the dumb light bulb." The distinguishing edge to their concept is that the device comes with an accompanying app, for iOS or Android smart devices, which unlocks numerous features. With the app, the user can turn LightFreq into a useful device for notifications according to the color of the light or for mood-centric applications such as strobe lights. Also, LightFreq will turn on and off automatically when you enter or leave a room. As for "follow-me" audio capabilities, the LightFreq starts playing music in the room you are in and when you move into a different room your music will follow, while turning off in the room you just left.
The first pilot study in Australia to give musicians the skills and training to critically assess music by what they hear rather than what they see begins this month at the Sydney Conservatorium of Music.The study aims to address a lack of skill and formal training in the industry that enables music judges to critically assess sound - an important skill when it comes to auditions and judging music in the 'real world'.
(Phys.org) —"One thing led to another," people often say. Events, discoveries and relationships are triggered by something previous. The iPhone case was designed only because the iPhone was invented first. A song became popular only after someone liked it.

Sam Ridgway has spent most of his life learning about dolphins and whales. Over his five-decade career he has asked these cetaceans various questions, including how deep they can dive and how depth affects their hearing. As he trained each animal to answer his questions, he rewarded them with tasty fish treats, and each time that they received a reward he remembers that they squealed. Initially he thought that the squeals were food signals, where animals communicate the presence of food to nearby members of their species. It was only when his wife Jeanette suggested that the squeals reminded her of delighted children that he began to ponder whether there was more to the cetaceans' cries: could they be genuine expressions of delight? Ridgway publishes his discovered that the time delay between dolphins and whales receiving a reward and their squeals is the same as the delay between a pleasant experience and dopamine release – suggesting that dolphins and whales experience pleasure – in the Journal of Experimental Biology.
Words in the English language are structured to help children learn, according to research. Words like "woof" accurately represent the sound of a dog while sounds with similar meanings may have a similar structure, such as the "sl" sound at the beginning of a word often has negative properties as in "slime, slur, slum, slug."
Whether the problem is health, enemies, poverty or difficulty with aging, “Take your burden to the Lord and leave it there,” suggested the late gospel musician Charles A. Tindley. But when it comes to easing anxiety-related disorders, prayer doesn’t have the same effect for everybody, according to a researcher.
(Phys.org) —Physicist Holger Hennig, currently with OptWare in Munich, Germany, has developed a stochastic model to describe synchronization that occurs in human musical rhythms that involve more than one person. In his paper published in Proceedings of the National Academy of Sciences, Henning describes how he discovered that when two musicians are playing together, a beat played by one person can depend on up to several minutes of the other person's prior interbeat intervals—the model he developed can be used, he claims, to produce more natural sounding computer generated music.
