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 PhysOrg.com. “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. (PhysOrg.com) — 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 PhysOrg.com.

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 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 Ku:Rin is yet another attempt to explore environmentally friendly modes of transport. 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 PhysOrg.com 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. (PhysOrg.com) — Toyota Industries intends to apply for a Guiness World record for the fastest car driven by a compressed-air engine, after its Ku:Rin, as the vehicle is called, reached 129.2km/h (80.3 mph)on a test run earlier this month.

© 2013 Phys.org 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?

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 (Phys.org) —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 Phys.org 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.

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.

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 Society

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.

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.

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.”

Heavy smokers are likely to gain more weight after quitting than light to moderate smokers, says a new study.“This is good news for light to moderate smokers who are concerned about weight gain. It means that in the long term, quitting smoking will not make that big of an impact on their weight,” said one of the researchers Susan Veldheer from Penn State Milton S Hershey Medical Centre in Pennsylvania, US.Quitting smoking may lead to some weight gain but how much weight gain depends on the individual.

Smokers of 25 or more cigarettes per day reported 23 pounds of weight gain that could be attributed to quitting cigarettes and obese smokers reported 16 pounds of weight gain that could be directly attributed to quitting.“Being able to easily identify smokers who may gain more weight when they quit is important so that we can work with patients to tailor their treatment plan,” Veldheer noted. The findings were reported in the International Journal of Obesity.

Make-up and women have been complementary terms for ages, but how do the two genders react to women with makeup? Men think women who wear make-up on are more “prestigious”, while women think women with make-up on are more “dominant”, reveals new research.The findings suggest that make-up changes perceptions of status depending on who is making the judgement – males or females.The research is the first to report on how males and females perceive women who wear make-up differently. “While both sexes agree that women with make-up look more attractive when it comes to ‘high status’, it really depends on who is looking,” said researcher Viktoria Mileva, post-doctoral research fellow at the University of Stirling in Scotland. Also Read – ‘Playing Jojo was emotionally exhausting’“Men think women with make-up on are more prestigious, while women think women with make-up are more dominant,” Mileva noted. Research suggests that “high status” can be obtained through two main routes. “Alternatively, you can gain high status by prestige; by having positive merits and qualities that make others want to follow you,” she added. The findings were published in the journal Perception.The study also found that women held rather negative views of other women who wear make-up. “We did some follow-up studies as to why women might feel that other women with make-up are perceived as more dominant, and it looks like it might be related to jealousy and potential threat,” Mileva said. Also Read – Leslie doing new comedy special with Netflix“Women rating other women with make-up said they would be more jealous of them, think of them to be more promiscuous, and more attractive to men than their non-make-up wearing counterparts,” she noted.For example, at a job interview, knowing whether the hiring committee will consist of men or women might influence a female candidate’s decision about wearing make-up. “Whether the interviewers will view her as attractive, dominant, and/or prestigious can affect her and the interviewers’ actions and perhaps the outcome of the interview itself. Thus, understanding the potential implications of cosmetic use are important not only for the wearer, but also for the perceiver,” Mileva explained.

In February 1948, a resident of Clearwater, Florida came face to face with something totally unexpected. Walking the beach one morning, he stumbled upon a set of remarkable footprints in the sand. The prints were enormous, about 14 inches long and 11 inches wide, and, even more remarkably, had three toes, tipped with long claws. Florida Fringe Tourism tells the story of the strange tracks, which came out of the Gulf of Mexico at the south end of the beach and walked the shore for about two miles before returning to the water and disappearing. No one could figure out what made the footprints, but the four- to six-foot strides it took showed that whatever it was, it was big.Clearwater Florida Photo by 2candle CC BY 2.5The creature’s tracks showed up on the beaches of various Florida towns for about two years. Its tracks were seen in towns between Clearwater and Sarasota, earning it the name “Old Three Toes”. During that time, several people claimed to have spotted the monster, for what else could it be? It was described as a large, bird-like thing or a large furry log with a head shaped like a hog’s.People’s reactions ranged from baffled, to terrified, to skeptical. If it was some strange creature from the water, what havoc could it cause, if it chose? If it was a hoax, who would go to so much trouble, and to what end?More tracks were found along the shore of Suwannee River, 40 miles (60 kilometers) from the ocean.The strange tracks came to the attention of Ivan T. Sanderson, a zoologist of some repute, who wrote and commented on scientific issues in New York. Sanderson came to Florida to investigate and spent months studying the tracks and interviewing witnesses. He even dug up one print to take home, according to an article in the Tampa Bay Times.Sanderson was like the Indiana Jones of the zoology world. He’d made several trips to the African jungle for Cambridge University and the British Museum which he then used as fodder to write a best-selling book.He was also the person who came up with the term cryptozoology — referring to the pursuit of creatures out of legend, such as the Loch Ness Monster. If anyone could crack the mystery of those three-toed tracks, he believed it was him.Cryptoclidus model used in the Five TV programme, Loch Ness Monster: The Ultimate Experiment. Author: Ballista. CC BY-SA 3.0After doing extensive study and research, he determined that the prints couldn’t be a hoax. They seemed far too deeply imprinted to have been made by man or machine. He even went so far as to say he had spotted the creature himself.He described it as being about 12 feet long, grayish-yellow, and having large arms that resembled flippers. He also said it made big waves when swimming as if it had a powerful kick. His final conclusion was that the creature had to be an enormous penguin, as silly as the idea sounded. After that, tracks were spotted a few more times throughout the ‘50s, but after 1958 there were no more sightings of either prints or giant penguins.Photo by Orgone Research30 years later, on June 11, 1988 the mystery was finally solved. The St. Petersburg Times wrote an article stating that Old Three-Toes was a hoax. A man from Clearwater, Tony Signorini, had confessed that he and a prankster friend had been responsible for leaving the mysterious tracks all those years ago. The article’s writer went to Signorini’s auto shop to interview him, and, while she was there, he showed her a pair of very large, cast-iron feet with three toes.Related Video: The Hybrid Neanderthal Girl – Made from 2 different speciesAccording to Signorini, at the instigation of Al Williams, his friend and boss at the time, they created the thirty-pound feet. Williams had apparently been taken with photos from Smithsonian magazine which showed a dinosaur footprint that had been fossilized. After examining the print for a while, Williams came up with the idea to make feet that matched the prints and have a little fun.Photo by Orgone ResearchWhen the feet were complete and had been bolted to a pair of high-top tennis shoes, the two men loaded them into a rowboat and went to shallow water not far from shore, where Signorini would put the dino-feet on and waded out of the water.To make the tracks so far apart, Signorini would balance on one foot, swinging the opposite leg back and forth to work up the momentum to make a jump to the other foot. Since each of the metal objects weighed about 30 pounds, the feat took some time and some stamina.Over the years, Signorini would occasionally pull the feet out of hiding and tell friends and family the story of how the tracks came to be, and, over time, he has left the only major player around to remember.Photo by Orgone ResearchHis partner, Al Williams, died in 1970. Ivan Sanderson had taken his interest in cryptozoology elsewhere and had been pursuing things like Bigfoot and UFOs prior to his own death in 1973. Tony Signorini finally died in 2013, leaving the fabled feet to his son, Jeff.Read another story from us: The ‘Dogman’ of Michigan: A Legend with More Sightings than BigfootSince Jeff inherited his father’s feet, he’s been approached by a couple of historical organizations who expressed their interest in displaying the oddball pieces of Florida history, but Jeff has resisted, noting his father wanted to keep the feet in the family. When he was wondering what to do with them, one of his nieces called dibs, so the family’s legacy will remain.
