In radiation ventriloquism electromagnetic waves travel backwards

first_img Lens with ‘Super Resolution’ Could Improve Medical Imaging Applications So if electromagnetic radiation started flowing in reverse, back toward its source, it could cause serious confusion. But this is just what Cesar Monzon, a Senior Scientist at Enig Associates, Inc., in Silver Spring, Maryland, has discovered. In a recent study, he theoretically demonstrates that, under special conditions of geometry, location, and frequency, power may flow backwards in the direction of its source. The study is published in a recent issue of Physical Review Letters.“I have been working in diverse aspects of electromagnetics for a number of years, and I just happened to stumble on some solutions of Maxwell’s equations that exhibited a very unusual behavior,” Monzon told “It is counterintuitive because we observe that, in some portions of space, the power is actually flowing back in the direction of the sources. On the other hand, based on experience, and with very rare exceptions (that involve wave guidance in exotic circumstances), the radiated power always spreads out as it travels away from the sources. For example, thermal radiation travels in straight lines away from a heat source.”In Monzon’s theoretical set-up, a number of identical electromagnetic wave sources are aligned in a row. When they radiate power at a certain frequency, an unusual power flow pattern develops at a distance of about half a wavelength away from the sources. At this location, the power turns and flows back toward the source array, accompanied by a vortex formation. As Monzon explains, the backwards power flow is caused by interference from the multiple sources. The waves superpose in such a way that the phase gradient of the waves points backwards in certain regions. Mathematically speaking, the electrical terms must overcome a geometric term. Monzon likens this condition to that of a mechanical object whose kinetic energy must overcome the potential energy of a barrier in order to overcome the barrier – like a ball with momentum rolling up a hill. As Monzon notes, the backward power flow is being carried by an ordinary wave, in which the phase velocity, group velocity, and power all point in the same direction. Until now, power flowing toward its source has only been demonstrated for “backward” waves, where some of these characteristics are reversed. ( — Typically, electromagnetic waves travel away from their sources. For instance, a radar system emits radio waves that travel all the way to a target, such as a car or plane, before being reflected back to the source. Police officers and the military rely on the forward movement of the waves to determine the speed or location of an object. But the fact that ordinary waves are flowing backwards here results in some unusual effects. If an observer were to detect the backward-moving waves, it would seem as if the waves were originating from a “ghost” source in the opposite direction from the true source. Monzon shows that it’s possible to control the placement of the backwards power flow, and harness the effect for various applications, including deception. “On the case of deception, it appears possible that with current technology we can build a radiator (such as a radar) that can convince an observer, through measurements, that radiation is coming from a given direction, when in reality we are somewhere else, and perhaps even observing them,” he said. “The effect is real, not an illusion. The resulting effect on the observer is, however, akin to the illusion offered by a ventriloquist who manipulates his or her voice so that it appears that the voice is coming from elsewhere.”Monzon added that the phenomenon could also be applied to other areas, such as optics, acoustics, and water wave problems. “On the case of satellite antenna feeds, the theory indicates it may be possible to build these behind the main reflector dish, which will offer a clear field of view without blocking or the disadvantages derived from feed offsetting,” he explained. “The same principle applies to both transmit and receive antennas.”More information: Monzon, Cesar. “Anomalous Power Flow and ‘Ghost’ Sources.” Physical Review Letters 101, 083901 (2008).Copyright 2008 All rights reserved.

The genetically modified eggs were placed between a pair of electrodes to form a detector, which measures the current created when the receptors on the egg bind with the odor molecules. The frog egg detectors are far more sensitive and accurate than other biological smell receptors that use the physical vibrations of quartz rods that vibrate when target odor molecules bind to them. These detectors tend to give false positives when other molecules with similar molecular weights to the target molecules bind to them. The frog egg smell detectors were demonstrated in a robotic mannequin that shakes its head when it comes into contact with moth pheromones. It is capable of detecting solutions containing only a few parts per billion of the target molecule, and can distinguish between molecules with only slight differences such as -OH, -CHO and -C=O groups.The aim of future research is to use frog eggs to detect gases such as carbon dioxide. Takeuchi explained that the mosquito can detect people from the carbon dioxide they breathe out. This means the mosquito must have carbon dioxide receptors, and so if DNA is extracted from the mosquito and used to genetically modify the frog eggs, the eggs will also be able to detect the gas.Takeuchi said aother possible future application would be to create detectors for the ketone odor produced by people with diabetes or for aldehydes or other allergens in foods.The paper was published in the Proceedings of the National Academy of Sciences.

Toyota threewheeler does 803 mph on compressed air

first_imgToyota staged a media viewing of the car earlier this week at a factory in Aichi Prefecture. The car is described by observers as a “sleek rocket,” or “a pencil-shaped rocket,” and, maybe not as kindly, an “eco-friendly tricycle.” The vehicle is said to be interesting but not practical. The driving range is a key reason why skeptics say it is impractical, at least under its present stage of development.The car offers a driving range of only 2 miles (3.2 km). As with battery powered cars, the marketable barrier remains range, or what is being more frequently called range jitters. The distance the Ku:Rin can go would only be 2 miles without replenishing the air in the cylinders. This document is subject to copyright.

The tank was filled using a conventional air-conditioner compressor manufactured by Toyota.The car was developed at the company’s Dream Car Workshop, where its engineers made use of the principle of compressed air, which Toyota knows more than a little about. The company is recognized for its expertise in compressors that are part of air conditioners. Toyota turns out about 20 million compressors for car air-conditioners per year; the company is the world’s largest supplier of car air- conditioner compressors, in addition to making automobiles, engines and electronics components. © 2011 According to reports, a number of companies, besides Toyota, are working on air-powered cars but they are all in the research phase. Likewise, the Ku:Rin was designed and built by a group of engineers at the Dream Car Workshop, which is a Toyota sandbox/incubator for innovative ideas. Company engineers gather there outside work hours to engage in development projects. One of the engineers, Kenta Nakauchi, told NHK TV that they are not thinking about putting the car into production. Instead, they want to use their expertise to design unique cars. At the same time, they are not walking away from the challenge of drawbacks.Toyota said it will keep working on extending the travel distance.

Company pioneering new types of material for 3D printer ink

first_img © 2013 3-D printing, also known as additive manufacturing because of the nature of the process, is a relatively new science. A liquid material is applied to a base, allowed to dry, then applied again, over and over, resulting in the creation of a three-dimensional object. To date, most advancements in the field have centered around the printer—Emerging Objects is instead focusing on the material that is used as the ink.As noted on Rael and San Fratello’s website, plastic, the standard ink used as a base material for 3-D printers, is both limiting and environmentally unfriendly. Other materials, they say, allow for the creation of objects that look and feel different, and don’t pollute. One example is acrylic—objects printed using it as a base are brittle and rigid, similar to glass, but also have a smooth, powdery feel. Perhaps more exciting are printed objects that look like they are made out of wood. The base material is wood pulp, but because of the 3-D layering process, the resulting materials have a natural-grain appearance.The company points out that because their materials are made from natural local components, they cost much less than plastic. For example, they’ve printed objects made mostly of salt obtained from nearby San Francisco Bay. In addition, the size of the printed objects using the new materials is limited only by the size of the printer. The team is currently working on printing a room-sized object that, because it will be made mostly of salt, will look like it’s made out of milk.The objects being produced by Emerging Objects offer a glimpse of the exciting future of 3-D printing technology. At this point, it’s possible to imagine giant printers one day laying down new houses or skyscrapers, or even on-demand machines in our homes that conjure almost any object we desire—much like the replicator of Star Trek fame, perhaps?

First venomous crustacean discovered living in underwater caves

first_img Citation: First venomous crustacean discovered living in underwater caves (2013, October 23) retrieved 18 August 2019 from More information: The first venomous crustacean revealed by transcriptomics and functional morphology: remipede venom glands express a unique toxin cocktail dominated by enzymes and a neurotoxin, Mol Biol Evol (2013) DOI: 10.1093/molbev/mst199AbstractAnimal venoms have evolved many times. Venomous species are especially common in three of the four main groups of arthropods (Chelicerata, Myriapoda, Hexapoda), which together represent tens of thousands of species of venomous spiders, scorpions, centipedes and hymenopterans. Surprisingly, despite their great diversity of body plans there is no unambiguous evidence that any crustacean is venomous. We provide the first conclusive evidence that the aquatic, blind and cave-dwelling remipede crustaceans are venomous, and that venoms evolved in all four major arthropod groups. We produced a three-dimensional reconstruction of the venom delivery apparatus of the remipede Speleonectes tulumensis, showing that remipedes can inject venom in a controlled manner. A transcriptomic profile of its venom glands shows that they express a unique cocktail of transcripts coding for known venom toxins, including a diversity of enzymes and a probable paralytic neurotoxin very similar to one described from spider venom. We screened a transcriptomic library obtained from whole animals and identified a non-toxin paralogue of the remipede neurotoxin that is not expressed in the venom glands. This allowed us to reconstruct its probable evolutionary origin, and underlines the importance of incorporating data derived from non-venom gland tissue to elucidate the evolution of candidate venom proteins. This first glimpse into the venom of a crustacean and primitively aquatic arthropod reveals conspicuous differences from the venoms of other predatory arthropods such as centipedes, scorpions and spiders, and contributes valuable information for ultimately disentangling the many factors shaping the biology and evolution of venoms and venomous species.

Credit: PLoS ONE 6 (5): e19627, figure 1. doi:10.1371/journal.pone.0019627 ( —A research team with members from the U.K., Germany, and Mexico has confirmed the first known existence of a venomous crustacean. In their paper published in the journal Molecular Biology and Evolution, the researchers describe their study of Speleonectes tulumensis, of the group remipedes as well as their finding that it is indeed the first known crustacean to use venom to capture and kill prey. , Molecular Biology and Evolution © 2013 Journal information: PLoS ONE Remipedes are a type of crustacean, which is a subgroup of arthropods. Venom is of course found in a wide variety of arthropods such as spiders and scorpions, but never before has a crustacean (of which there are 70,000 known kinds) been known to create and use venom.Scientists have suspected S. tulumensis may be unique since they were first discovered living in underwater caves along coastlines in Mexico and Central America as far back as the 1980’s. They have hollow fangs on the sides of their head behind their jaws. No one’s been able to study them up close until now, however because of the difficulty in getting to where they live. In this latest effort, the team was able to collect some samples and then took them back to their lab. There they discovered that the one-of-a-kind creature actually has a complex venom delivery system, and that it produces more than one type of toxin.Specifically, they found that the tiny creature has muscles that contract to pump venom into the fangs, and another set they use for injection once prey is bitten (they are also able to squeeze off the fang chamber to prevent backwash). They also found that the venom has a both a neurotoxin and enzyme in it to deal with prey in two different ways. The neurotoxins (similar to those found in spider venom) act to disable prey, likely by causing spasms, while the enzymes (similar to those found in snake venom) break down body tissue allowing S. tulumensis to suck the body out of the shell and then to digest it.The researchers suggest that if one type of crustacean is venomous, it’s likely there are others that just haven’t been discovered yet. They also can offer no explanation as to why this particular creature out of all the others has developed the trait other than to note that it evolved in an environment that doesn’t have many food sources.

Scientists investigate unidentified radio sources

first_img WISE, Fermi missions reveal a surprising blazar connection (—A team of researchers led by Andrea Maselli of the Institute of Space Astrophysics and Cosmic Physics of Palermo, Italy, has conducted an observational campaign of a group of unassociated radio sources with NASA’s Swift space observatory. The observations were aimed at revealing the true nature of these so far unidentified sources.

The Swift spacecraft, scanning the universe in the gamma-ray, X-ray, ultraviolet, and optical wavebands, is an invaluable tool when it comes to studying gamma-ray bursts and other electromagnetic events. It has already proved its scientific importance in many ways, for example by performing the first sensitive hard X-ray survey of the sky.Recently, Maselli and his team employed Swift to observe 21 bright radio sources included in the revised Third Cambridge Catalogue (3CR) of radio sources. The catalog contains celestial radio sources detected at 178 MHz that could advance our knowledge about the nature and evolution of powerful radio galaxies and quasars.However, some sources described in the 3CR catalog, including these detected by the NRAO VLA Sky Survey (NVSS), are not only unobserved in X-rays, but are, in fact, completely unidentified, lacking an assigned optical or infrared counterpart. The authors of the paper decided to fill this gap by conducting a supplementary optical-to-X-ray campaign with the Swift spacecraft, in order to better characterize the properties of these unidentified sources.”We have investigated a group of unassociated radio sources included in the 3CR catalog to increase the multi-frequency information on them and possibly obtain an identification,” the researchers wrote in the paper.Each of the 21 sources was observed by two telescopes onboard Swift – the X-ray Telescope (XRT) and the Ultraviolet/Optical Telescope (UVOT). The observation campaign lasted from November 2014 to March 2015.According to the research, out of these 21 investigated sources, nine exhibit significant emission in the soft X-ray band. The scientists managed to assign an infrared counterpart in the AllWISE (All Wide-field Infrared Survey Explorer) catalog for these nine sources and in four cases with no soft X-ray association.”After conducting Swift observations of 21 bright NVSS sources corresponding to 3CR sources classified as unassociated in the third update of the 3CR catalogue, we have obtained new X-ray detections for nine of them. Moreover, cross-matching the NVSS with the recent AllWISE Catalogue, we have found a WISE counterpart to all these nine X-ray sources, as well as to four cases with no X-ray detection,” the paper reads.What baffled the researchers is that no optical/UV counterpart has been found by UVOT, what lead them to an assumption that these unidentified radio sources should be classified as obscured active galaxies. However, the team added that it is too early to draw final conclusions as spectroscopic observations are needed to confirm this hypothesis.”Our analysis suggests that a spectroscopic analysis in the infrared range will be more helpful to identify their nature as well as potentially obtain a redshift measurement,” the team wrote.

We have carried out an observational campaign with the Swift satellite to observe with the UVOT and the XRT telescopes the field of view of 21 bright NVSS sources within the positional uncertainty region of the 3CR sources. Furthermore, we have searched in the recent AllWISE Source Catalogue for infrared sources matching the position of these NVSS sources. We have detected significant emission in the soft X-ray band for nine of the investigated NVSS sources. To all of them, and in four cases with no soft X-ray association, we have associated a WISE infrared counterpart. Eight of these infrared candidates have not been proposed earlier in the literature. In the five remaining cases our candidate matches one among a few optical candidates suggested for the same 3CR source in previous studies. No source has been detected in the UVOT filters at the position of the NVSS objects, confirming the scenario that all of them are heavily obscured. With this in mind, a spectroscopic campaign, preferably in the infrared band, will be necessary to establish the nature of the sources that we have finally identified. , arXiv Journal information: Monthly Notices of the Royal Astronomical Societylast_img read more

Scientists have noted that other animals make sounds that correlate to their emotional states, as well. In this new effort, the researchers sought to learn whether human beings are able to recognize which sort of emotional state other animals are experiencing based only on the sounds they emit.In the experiment, volunteers listened to prerecorded animal sounds and attempted to identify the emotional state of the creature that made it. To rule out the possibility that some sounds might be more or less recognizable by people who speak different languages, the volunteer group included people who spoke German, English or Mandarin. In all, the researchers played 180 vocalizations for the volunteers representing a very diverse group: black-capped chickadee, hourglass treefrog, American alligator, common raven, giant panda, barbary macaque and the African bush elephant. The researchers also carried out an acoustic analysis of the sounds on the recordings, comparing the sounds with people’s reactions to them and found that humans use many acoustic clues to understand emotional noises made by other animals.The researchers report that the volunteers were quite accurate in their ability to distinguish animal emotional vocalizations, showing an ability to distinguish between such sounds as cries of pain, exhilaration or fear in all of the land animals—regardless of which language the people spoke.This finding, the researchers suggest, hints at the possibility of common ancestral roots that evolved as a means of survival—being able to recognize the sounds other animals make when threatened, for example, could help humans prepare for what lies ahead.center_img (—A team of researchers with members from Germany, France, the Netherlands and Canada has found that human beings are able to accurately recognize emotionally based vocalizations made by a wide variety of land vertebrates.

If this hypothesis is true, we should expect to find cross-species acoustic universals in emotional vocalizations. Studies suggest that acoustic attributes of aroused vocalizations are shared across many mammalian species, and that humans can use these attributes to infer emotional content. But do these acoustic attributes extend to non-mammalian vertebrates? In this study, we asked human participants to judge the emotional content of vocalizations of nine vertebrate species representing three different biological classes—Amphibia, Reptilia (non-aves and aves) and Mammalia. We found that humans are able to identify higher levels of arousal in vocalizations across all species. This result was consistent across different language groups (English, German and Mandarin native speakers), suggesting that this ability is biologically rooted in humans. Our findings indicate that humans use multiple acoustic parameters to infer relative arousal in vocalizations for each species, but mainly rely on fundamental frequency and spectral centre of gravity to identify higher arousal vocalizations across species. These results suggest that fundamental mechanisms of vocal emotional expression are shared among vertebrates and could represent a homologous signalling system.last_img read more

IDA join hands with KMC to conduct drives against tobacco consumption

first_imgKolkata: The Indian Dental Association (IDA) will join hands with the Indian Medical Association (IMA) and Kolkata Municipal Corporation in spreading awareness against the consumption of tobacco.As a part of its anti-tobacco campaign, the IDA has taken up a host of initiatives on the occasion of World No Tobacco Day on 31 May. The health awareness camp will be organised at Dr R Ahmed Dental College and Hospital. The IDA has taken a pledge to hold various health camps to make people aware of the ill-effects of tobacco consumption in various forms. Also Read – Heavy rain hits traffic, flightsRallies will be held, where people from all walks of society, will take part only to highlight the danger of consuming tobacco. Various others anti-tobacco drives will also be organised on the occasion of World No Tobacco Day. IDA organises regular health talks, check-up camps and give suggestions to the state government and thus helps in implementing the anti-tobacco laws in West Bengal.India is home to one of the largest number of tobacco consumers in the world and West Bengal contributes largely to that. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedAccording to Global Adult Tobacco Survey 2010(GATS), 36.3% of the population of West Bengal uses tobacco in some form. This would amount to as many as 2.5 crore of people.Oral cancer has been on the rise. Oral cancer constitutes about 40% of all forms of cancer in our country and 30% of them stem from the use of tobacco. People from all sections of the society are victims. Strict measures should be taken to check the use of Gutkha among the people in the state and also a ban on smoking in public places. Smokeless chewing of tobacco like gutkha, khaini, paan and so on leaves people of Bengal vulnerable to various ailments. Also, cigarettes, bidis and alcohol increase the risk further. Almost in all cases, the patient comes for check up due to toothache and finds he is in a pre-cancerous state, a radiation oncologist in the city said.Dr Raju Biswas, State Secretary of the Indian Dental Association said: “Tobacco epidemic is one of the major health threats to the public health system. Our initiative is to free West Bengal from the clutches of Tobacco epidemic. It is very encouraging to get full support from the state government.”last_img read more
