Analogy of cochlea as resonator could lead to artificial copies

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Using squirting waves and the SAW configuration, the cochlea could theoretically provide sharp resonance frequencies typical of the human ear, in the range of 20 to 20,000 Hz.“The idea is that cells are not lonely, independent entities unaware of other cells,” said Bell. “Instead, cells appear in populations and cooperatively interact so as to perform signal processing. We have long known that nerve cells process information via a network of interactions (neural nets), but here we see a preneural example: outer hair cells act both to detect sound and pass it on to neighboring cells, which do the same. Shuttling of signals back and forth leads to positive feedback and frequency analysis, and this might prompt us to look for similar interactions among other sensing cells. Visual, olfactory, and balance cells, for example, could well work in similar ways.”Bell speculates that the main reason past artificial cochleas fell short is that their designers focused on the passive traveling wave picture. But building a cochlea based on the active processes residing in the resonator analogy may, Bell thinks, open up a much more effective way forward.“A SAW-like cochlea would form a rugged spectral analyzer—a reasoning behind existing artificial cochleas—but it could be much more sensitive then existing prototypes,” said Bell.Bell explained that more experiments and testing will determine if this idea is accurate. He also added that there may be some exciting characteristics of the ear to discover.“Future research needs to be directed to validating the SAW resonator model,” he said. “But then there are finer features which call for explanation, too. What is the purpose of the ‘V’ shape of the stereocilia, for example? There is reason to think it could relate to detecting musical ratios in sounds, and if so this would give a marvelous physical underpinning to our remarkable musical sense. The cochlea may be highly tuned—and musical.”Citation: Bell, Andrew. “Sensors, motors, and tuning in the cochlea: interacting cells could form a surface acoustic wave resonator.” Bioinspiration and Biomimetics 1 (2006) 96-101.By Lisa Zyga, Copyright 2006 PhysOrg.com.

A SAW resonator (top) has two sets of electrodes that generate and detect electromechanical ripples. With a similar structure, the cochlea (bottom) could use outer hair cells to sense and create standing waves. Image Credit: Andrew Bell. In developing his new idea, Bell was inspired by a discovery in 1978 that most human ears continuously emit very pure, soft tones—sounds which can be picked up with a sensitive microphone. The current theory of a hydrodynamical traveling wave stimulating hair cell stereocilia does not easily accommodate such fine tuning, leading Bell to propose that the outer hair cells in the cochlea actively cooperate to amplify sound. “When you listen to a recording of the sound that the cochlea makes, you hear something like a carillon of wind chimes,” Bell told PhysOrg.com. “It’s easy to get the impression that something seems to be resonating.”He considered a design where the cochlea would function like a SAW resonator, a device in solid-state electronics commonly used in cell phones due to its small size. SAW resonators use rows of electrodes to process signals by creating electromechanical waves between them whose wavelengths correspond to the spacing of the electrodes. Bell noted a striking characteristic of the outer hair cells: they always lie in three well-defined rows, much like the electrodes on a SAW resonator. Bell thinks that the waves align with the rows of hair cells, with the first and third rows being in antiphase with the middle row. Such SAW-like behavior would also correspond well with results from past experiments in auditory science.Further, like a SAW resonator, the cochlear amplifier would operate in a feedback circuit mediated by the waves. Because the hair cells are linked to soft structures such as the gelatinous tectorial membrane, feedback in the cochlea would require a slow-moving wave, one with a very short wavelength. Recently, a prime candidate for such a wave has been identified: called “squirting waves,” these waves arise in fluids constrained in ways similar to those found in the cochlea. center_img In attempting to construct an artificial cochlea—and faced with limited knowledge of how the living chamber works—scientists might need to look no further than a simple electronic device: a surface acoustic wave (SAW) resonator. Recently, scientist Andrew Bell suggested that the cochlea exhibits similar structure and electromechanical properties to this common piece of circuitry.

The common understanding of the workings of the cochlea centers on its passive behavior, in which tiny hair cells create electrical signals from vibrations in the surrounding fluid.last_img read more

The company designed the Orbita mouse to overcome some of the limitations of conventional mice by replacing the conventional scroll wheel with a 360° spinning “jog wheel.” An oracle for object-oriented programmers Citation: Spinning ‘Orbita’ Mouse Available in January (2008, December 15) retrieved 18 August 2019 from https://phys.org/news/2008-12-orbita-mouse-january.html Cyber Sport’s Orbita mouse replaces the scroll wheel with a spinning jog wheel for more intuitive navigation. Image credit: Cyber Sport. Cyber Sport says that the new mouse provides a more intuitive control center, better ergonomic handling, and higher efficiency. Rather than scrolling down a page with jerky vertical finger movement, users of the Orbita mouse can navigate by rotating the mouse left or right in a natural dialing motion.The Orbita mouse has a small white button at the top, which serves as the orientation button. Pressing that button calibrates the mouse in the same direction as the arrow on the screen is currently pointing, so that left, right, up, and down navigating directions are based on that orientation. The orientation feature is particularly useful for navigating in 3D gaming environments, Google Earth maps, and 3D CAD designs. The mouse could also have advantages in audio and video applications for frame-by-frame manipulation. Because the mouse can be used at any angle, the buttons can also be used at any angle. The mouse has one “push” button and a series of “squeeze” buttons to serve as a “right click.”A third button, the “jog dimple” button, can be used to either spin the mouse or it can work like a standard scroll wheel button on a conventional mouse. By pressing this button, users can also switch between vertical and horizontal scrolling. Besides rotating the mouse with a finger, the device is sensitive enough that users can flick it to make it spin freely and continuously. The Orbita mouse, which works with both Macs and PCs, will be sold for $98.50 starting in January 2009. More information: http://www.cyberesport.com/via: Engadget© 2008 PhysOrg.comlast_img read more

Foldit gamers improve protein design through crowdsourcing

first_img Journal information: Nature Biotechnology Paper uncovers power of Foldit gamers’ strategies © 2011 PhysOrg.com This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Proteins are made up of long chains of amino acids which wind up in various shapes due to the chemical properties of each link in the chain. Eventually three dimensional shapes emerge, sort of like balloon animals, and the shape a protein takes determines the activity that it performs. One activity that some proteins, such as enzymes provide, is acting as a catalyst for chemical reactions. Researchers are always interested in finding better catalysts because the better they are the more money can be saved in manufacturing costs of materials that come about as a result of chemical reactions.In earlier versions of the Foldit game, players were simply given existing proteins to play with and asked to find the minimal energy state for them by folding them in optimum ways, this latest version has gone much farther by giving players the opportunity to come up with a whole new protein design.To create the new design, gamers were given a simple beginning structure and some basic ideas about the goal of the new protein, in this case to serve as a better catalyst for a class of Diels-Alder reactions, which are used to synthesize many commercial products. After offering some ideas such as remodeling certain sections to make them behave in certain ways, the gamers went to work folding the proteins using the tools at hand.The first go-round proved mostly futile, with few gamers coming up with good improvements. To improve the results, the team took the best foldings from the first round and fed them back into the game allowing gamers to improve on them. This time, the crowd proved quite adept at coming up with a much improved enzyme; they succeeded in designing a new catalyst that was a hundred times more active than prior designs.Unfortunately, the new protein isn’t really useful though because the chemical reaction that it’s used for doesn’t have any purpose except to serve as a proof of concept. That will change very soon though. The current protein the gamers are working on is an improvement on a protein inhibitor to block the spread of the virus responsible for the 1918 flu pandemic.

De novo enzyme design has generated catalysts for several reactions, but with lower catalytic efficiencies than naturally occurring enzymes. Here we report the use of game-driven crowdsourcing to enhance the activity of a computationally designed enzyme through the functional remodeling of its structure. Players of the online game Foldit5, 6 were challenged to remodel the backbone of a computationally designed bimolecular Diels-Alderase3 to enable additional interactions with substrates. Several iterations of design and characterization generated a 24-residue helix-turn-helix motif, including a 13-residue insertion, that increased enzyme activity >18-fold. X-ray crystallography showed that the large insertion adopts a helix-turn-helix structure positioned as in the Foldit model. These results demonstrate that human creativity can extend beyond the macroscopic challenges encountered in everyday life to molecular-scale design problems. (PhysOrg.com) — Gamers on Foldit have succeeded in improving the catalyst abilities of an enzyme, making it 18-fold more active than the original version. The idea is the brainchild of University of Washington scientist Zoran Popovic who is director of the Center for Game Science, and biochemist David Baker. Together they have created the Foldit site which is a video game application that allows players to work with protein design, rather than shooting virtual aliens. By giving players a basic concept to work with and a box of tools, the team has created a means for crowd sourcing protein design. Those that come up with the most efficient way to fold an enzyme get the most points.

The optomechanical Kerker effect Controlling light with vibrating nanoparticles

first_img © 2019 Science X Network Credit: Poshakinskiy & Poddubny. “Even though the light scattering has been understood for more than a century after the works of Rayleigh, Raman, Landsberg and Mandelstam, it remains both a fundamental and applied challenge to route light scattered at the nanoscale in the direction at will,” Alexander Poshakinskiy, one of the researchers who carried out the study, told Phys.org. “The ability to control the direction, frequency and polarization of the scattered light is essential for operation of optical circuits.”Devices that can control the direction of scattered light could have numerous useful applications, particularly for the operation of antennas and routing of light. In the 1980s, researchers theorized that a directional scattering of light can be achieved via the so-called Kerker effect. This effect essentially exploits the interference of electric and magnetic dipole emission patterns, which have different spatial parity, yielding the suppression of forward or backward scattering when they are superposed. “Realization of the conventional Kerker effect requires the particles to have electric and magnetic polarizabilities of the same strength,” Poshakinskiy said. “However, this is challenging because magnetic response at optical frequencies is extremely weak. A possible workaround is to use large submicron-size nanoparticles hosting both electric and magnetic Mie resonances. However, optical Kerker effect for the particles smaller than the wavelength in the medium is still unfeasible. In our work, we show that even small particles, that lack magnetic response when at rest, do acquire it when they start trembling in space, enabling realization of what we call optomechanical Kerker effect.”In the optomechanical Kerker effect, proposed by Poshakinskiy and his colleague Alexander Poddubny, the tunable directional scattering of light is attained for a particle that lacks magnetic resonances as it trembles in space. The trembling motion of the electric dipole in space leads to the appearance of a magnetic dipole, as one could expect from the Lorentz transformation. This document is subject to copyright.

More information: A. V. Poshakinskiy et al. Optomechanical Kerker Effect, Physical Review X (2019). DOI: 10.1103/PhysRevX.9.011008 Journal information: Physical Review X Explore further Citation: The optomechanical Kerker effect: Controlling light with vibrating nanoparticles (2019, March 6) retrieved 18 August 2019 from https://phys.org/news/2019-03-optomechanical-kerker-effect-vibrating-nanoparticles.html For the Kerker effect to occur, particles need to have electric and magnetic polarizabilities of the same strength. This, however, is very challenging to achieve, as magnetic optical resonances in small particles are relatively weak. Researchers at Ioffe Institute, in St. Petersburg, have recently shown that a similar effect can be attained when small particles are trembling in space. Tiny particles with varied shapes scatter light in useful and unusual ways “We show that magnetic and electric dipole induced in the trembling particle by incident light counterintuitively are of the same order when inelastic scattering is considered,” Poshakinskiy explained. “The phase difference between the electric and magnetic dipoles is governed by the frequency dependence of the particle permittivity. For a resonant particle, this enables control of the scattering direction via the detuning of light frequency from the resonance: The light is scattered preferably forward at resonance and backward away from it. ” The researchers show that in the optomechanical Kerker effect, the figure of merit that quantifies how much of the light is scattered in a particular direction compared to all other directions (i.e. directivity), can be as high as 5.25. This exceeds the directivity of 3 attained in the classical Kerker effect, due to the additional electric quadrupole momentum induced by the mechanical motion. In their study, Poshakinskiy and Poddubny also introduced a second effect, which they refer to as ‘the optomechanical spin-Hall effect.’ In this effect, a directional inelastic scattering of light, depending on its circular polarization, is realized for a small trembling particle.”The optomechanical spin-Hall effect can be achieved when a particle vibrates around a circular trajectory rather that a straight line,” Poshakinskiy said. “We show that the angular mechanical momentum of the particle can be transferred to the spin of light. Then the electromagnetic waves scattered by the trembling particle to the left and to the right attain opposite circular polarization.” The findings gathered by Poshakinskiy and Poddubny suggest that the interaction between light and mechanical motion has an intrinsically multipolar nature. This quality could be exploited in a variety of systems, ranging from cold atoms to two-dimensional materials and superconducting qubits. “We believe that the proposed optomechanical Kerker opens a new multidisciplinary field by uncovering, for the first time, to our knowledge, a highly untrivial link between optomechanics and nanophotonics,” Poshakinskiy said. “From a practical point of view, the proposed effects can be used to design non-reciprocal nanoscale optical devices.”Optical non-reciprocity, meaning that light is transmitted forward and backward through an optical circuit differently, is crucial for optical signal processing. Most existing non-reciprocal optomechanical devices are based on optical resonators, which limit their minimal size to sub-microns. The results collected by Poshakinskiy and Poddubny show that tunable optomechanical non-reciprocity can also occur at nanoscale when using small trembling particles with resonant polarizability. “Optical non-reciprocity is also a key ingredient for the design of photonic topological circuits,” Poshakinskiy added. “In an array of trembling particles, one can expect a disorder-robust propagation of light and sound, ensured by the time modulation of optical and mechanical properties.”The study carried out by Poshakinskiy and Poddubny shows how the tunable directional scattering of light can be achieved at nanoscale, introducing the optomechanical Kerker and spin-Hall effects. In the future, their findings could have several interesting applications, for instance, informing the design of non-reciprocal topological circuits. The researchers are now planning to demonstrate the optomechanical Kerker effect in lab experiments. “The proof of concept would be observation of the directional backscattering by trembling objects, which can be realized even away from material resonances,” Poshakinskiy said “We believe that this can be done in a variety of systems e.g., semiconductor quantum dots, transitional metal dichalcogenides or graphene. However, the key feature of the optomechanical Kerker effect is the possibility to switch the direction of scattering between forward and backward. This requires particles with extremely sharp resonances in their electromagnetic response. Our estimations show that such switching can be realized for cold atoms in optical traps or superconducting qubits in radio-frequency circuits.”last_img read more

In one of the films, the nefarious Borg travel back in time to prevent the first Vulcan space ship from landing on our world and offering friendship.The Dharma Planet Survey, in a new study led by University of Florida (UF) astronomer Jian Ge and a team that includes Tennessee State University (TSU) astronomers Matthew Muterspaugh and Gregory Henry, has “discovered” the planet Vulcan.Artist rendition of the planet found around 40 Eridani A (University of Florida).“The new planet is a ‘super-Earth’ orbiting the star HD 26965, which is only 16 light years from Earth, making it the closest super-Earth orbiting another Sun-like star,” says Ge in UF News. “The planet is roughly twice the size of Earth and orbits its star with a 42-day period just inside the star’s optimal habitable zone.”Super-Earths have a mass that is far greater than that of Earth but smaller than that of other gigantic, gaseous planets. This newly found one’s mass is twice that of our home planet and it orbits its host star “with a 42-day period just inside the star’s optimal habitable zone,” said Ge.Photo of Leonard Nimoy as Mr. Spock from the television series Star Trek.The discovery was made using the Dharma Endowment Foundation Telescope (DEFT), a 50-inch telescope that is mounted on top of Mount Lemmon in Arizona. The planet is the first “super-Earth” detected by the Dharma Survey.It’s being compared to the fictional Vulcan because Gene Roddenberry, the creator of Star Trek, once said the star HD 26965, also known as 40 Eridani A, was the ideal home system for Spock.In 1991, Roddenberry and several Harvard-Smithsonian Center for Astrophysics astronomers wrote in a “letter to the editor” in Sky and Telescope that 40 Eridani A would be the perfect one for Vulcan.Gene Roddenberry in 1971.“Presumably Vulcan orbits the primary star, an orange main-sequence dwarf of spectral type K1. … Two companion stars — a 9th magnitude white dwarf and an 11th magnitude red dwarf — orbit each other about 400 astronomical units from the primary. They would gleam brilliantly in the Vulcan sky,” they wrote in the letter.The newly found planet is situated at the exact place where Roddenberry and the astronomers had imagined Vulcan to be.Vulcan hz-590According to the Daily Galaxy, “Star Trek fans may know the star HD 26965 by its alternative moniker, 40 Eridani A,” says Henry, who collected precise brightness measurements of the star at TSU’s observatory needed to verify the presence of the planet. “Vulcan was connected to 40 Eridani A in the publications Star Trek 2 by James Blish and Star Trek Maps by Jeff Maynard,” explains Henry.40 Eridani.

VIDEO Giancarlo Stanton gets booed after 5 Ks in his first game

first_imgGiancarlo Stanton was far and away the biggest free agency acquisition of the baseball offseason, and not surprisingly, Yankee fans are expecting big things from Stanton and bash brother Aaron Judge for many years to come.New York is also a tough freakin’ town, and Stanton got his first taste of the Gotham venom in his first ever game at Yankee Stadium after taking striking out 5 times against the Rays, today. It was the first time Stanton had K’d 5 times in a game in his career and Yankee fans celebrated the occasion by booing him all the way back to the dugout. Oh, yeah, the Yankees had a comfortable 9-4 lead at the time of his 5th K, and won the game 11-4. Good god, people.The pinstripes always look great, but the other half of the equation is the obligation to please an unrelenting fanbase. Watch Gio get a New York welcome in his first game. It ain’t Miami.More boos for Giancarlo Stanton.

Gadgets That Can Battle the Elements

first_imgJanuary 8, 2013 There’s always that moment of irrational hope just as disaster strikes a personal electronic device. Maybe your cell phone will be the first ever to survive an accidental bath, or perhaps your laptop, tumbling off the table, won’t shatter. The good news? If your device has a high Ingress Protection (IP) rating, it just might tough it out. The IP uses a two-digit system: The first digit (from 0 to 6) measures protection against solid objects like hands, wires and dust; the second (from 0 to 8) measures the level of protection against liquids, from condensation to total immersion. The rough-and-tumble devices showcased here didn’t just earn passing grades–they weathered our own real-world trials with flying colors. Hear from Polar Explorers, ultra marathoners, authors, artists and a range of other unique personalities to better understand the traits that make excellence possible. 3 min read Tough StuffGetac X500 (from $4,999)Scored at IP65, this 16-inch laptop can fight off dust, splashes of water and, with its magnesium-alloy case, maybe even a few battlefield foes as well.

For the First Time Ever 3D Printed Pill Receives FDA Approval

first_img 2 min read Opinions expressed by Entrepreneur contributors are their own. For the first time, the U.S. Food and Drug Administration has approved a 3-D printed pill.Developed by Aprecia Pharmaceuticals, the pill will be used by patients with epilepsy to control seizures. But the FDA’s stamp of approval could have far broader applications; Aprecia Pharmaceuticals plans to develop other medications using 3-D printing technology, the BBC reports.While 3-D printing technology has been dinged for generating outsized expectations that have yet to be fulfilled, in health care its impact has already been profound. From customized 3-D printed prosthetics and hip replacements, to 3-D printed bones, skin and personalized replicas of tumors (for use in cancer treatment), the industry is a place where novel technology and actual use cases have intercepted to create real innovation.Related: 3-D Printing Points Way to Smarter Cancer TreatmentPills fit neatly into this vein. Not only does the technology – which builds up a tablet in layers – allow for more concentrated pills, it could also make it easier and more cost-efficient (an adjustment to software, instead of the traditional manufacturing process) to create pills precisely tailored for a patient’s exact dosage.In addition, “for the last 50 years we have manufactured tablets in factories and shipped them to hospitals and for the first time this process means we can produce tablets much closer to the patient,” Dr. Mohamed Albed Alhnan, a lecturer in pharmaceutics at the University of Central Lancashire, told the BBC.Related: FDA Approves First Mind-Controlled Prosthetic Arm August 4, 2015 Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.
