U.S. to increase wild bird avian flu tests A team at the Zoological Society of London, led by Dr. Becki Lawson, is tracking an increased spread of an avian pox virus that is rapidly moving through the UK and affecting the great tits. Researchers are asking the public to help them track the spread of this virus. The virus was first discovered in the UK in 2006 but before then had been confined to birds in Austria, Czech Republic, Scandinavia and Slovakia. Until this year, the virus had stayed contained to south-east England but is now spreading to the north and west.Avian pox causes wart-like tumor growths on the birds, predominately around the eyes and beaks. Researchers do not know if the tumors are fatal or not but they do affect the bird’s ability to see and eat, leaving them more vulnerable to predators and starvation.Avian pox can be transmitted via insect bites, direct contact with other birds or indirect contact in places where multiple birds frequent, such as bird feeders, bird baths and garden perches. The researchers explain that the virus can remain in the environment for weeks or months.They are recommending that homeowners with bird baths and feeders keep them disinfected on a regular basis in order to try and reduce the spread of the virus. They are unable to give medicine to free-range birds and are hoping to find a way to prevent the transmission.Avian pox has also been noted in birds such as the dunnock, house sparrow, starling and wood pigeon however, it seems to affect these birds in a much milder form than it does the great tits.The RSPB has asked that residents report possible sightings of birds displaying symptoms of the avian pox to the RSPB Wildlife Enquiries Unit at 01767 693690. © 2010 PhysOrg.com Explore further Citation: UK garden bird avian pox virus spreading (2011, August 4) retrieved 18 August 2019 from https://phys.org/news/2011-08-uk-garden-bird-avian-pox.html
Journal information: arXiv More information: Space-time crystals of trapped ions, arXiv:1206.4772v1 [quant-ph] arxiv.org/abs/1206.4772AbstractGreat progresses have been made in exploring exciting physics of low dimensional materials in last few decades. Important examples include the discovering and synthesizing of fullerenes (zero dimensional, 0D), carbon nanotubes (1D) and graphene (2D). A fundamental question is whether we can create materials with dimensions higher than that of conventional 3D crystals, for example, a 4D crystal that has periodic structures in both space and time. Here we propose a space-time crystal of trapped ions and a method to realize it experimentally by confining ions in a ring-shaped trapping potential with a static magnetic field. The ions spontaneously form a spatial ring crystal due to Coulomb repulsion. This ion crystal can rotate persistently at the lowest quantum energy state in magnetic fields with fractional fluxes. The persistent rotation of trapped ions produces the temporal order, leading to the formation of a space-time crystal. We show that these space-time crystals are robust for direct experimental observation. The proposed space-time crystals of trapped ions provide a new dimension for exploring many-body physics and emerging properties of matter.

He envisioned a rotation with a ring of ions that flowed separately rather than as a stream, likening it to a mouse running around inside of a snake laying as a circle. The bulge would flow, rather than the snake itself spinning and would just keep on going, potentially forever. The problem was, he couldn’t figure out how such a crystal structure could be created in the real world.Taking Wilczek’s original idea, but not his method for creating a real world example, Li et al, suggest that to create a space-time crystal all that’s needed is a better ion trap. They believe that if ions could be forced using such a trap, into a ring at very low temperatures, as a superconductor, all that would be needed would be a little nudge from a tiny bit of a magnetic field to cause the ions to begin rotating as a single ring. Because there would be no resistance, and because of their natural mutual repulsion, the ring should then continue rotating indefinitely with no additional injection of energy, resulting in the space-time crystal that Wilczek imagined.The team is quick to point out, for those that might be making the jump, that the result would not be the mythical perpetual motion machine because no energy could be extracted from the space-time crystal. They do believe that building an actual space-time crystal should be possible though, in the near term if a future team has the funds necessary to overcome the difficulty of creating a better ion trap.

See arXiv:1206.4772v1 paper for details. (Phys.org) — Earlier this year, theoretical physicists Frank Wilczek, of MIT put forth an idea that intrigued the research community. He suggested that it should be possible to construct a so called space-time crystal by adding a fourth dimension, movement in time, to the structure of a crystal, causing it to become an infinitely running clock of sorts. At the time, Wilczek acknowledged that his ideas on how to do so were inelegant, to say the least. Now another international team led by Tongcang Li has proposed a way to achieve what Wilczek proposed using a far more elegant process. They have posted a paper on the preprint server arXiv describing what they believe is a real-world process for creating an actual space-time crystal that could conceivably be carried out in just the next few years. © 2012 Phys.org Time crystals could behave almost like perpetual motion machines This document is subject to copyright.

Quantum equation predicts universe has no beginning (2015, February 9) retrieved 18 August 2019 from https://phys.org/news/2015-02-big-quantum-equation-universe.html No singularities nor dark stuffIn addition to not predicting a Big Bang singularity, the new model does not predict a “big crunch” singularity, either. In general relativity, one possible fate of the universe is that it starts to shrink until it collapses in on itself in a big crunch and becomes an infinitely dense point once again. Ali and Das explain in their paper that their model avoids singularities because of a key difference between classical geodesics and Bohmian trajectories. Classical geodesics eventually cross each other, and the points at which they converge are singularities. In contrast, Bohmian trajectories never cross each other, so singularities do not appear in the equations.In cosmological terms, the scientists explain that the quantum corrections can be thought of as a cosmological constant term (without the need for dark energy) and a radiation term. These terms keep the universe at a finite size, and therefore give it an infinite age. The terms also make predictions that agree closely with current observations of the cosmological constant and density of the universe.New gravity particleIn physical terms, the model describes the universe as being filled with a quantum fluid. The scientists propose that this fluid might be composed of gravitons—hypothetical massless particles that mediate the force of gravity. If they exist, gravitons are thought to play a key role in a theory of quantum gravity.In a related paper, Das and another collaborator, Rajat Bhaduri of McMaster University, Canada, have lent further credence to this model. They show that gravitons can form a Bose-Einstein condensate (named after Einstein and another Indian physicist, Satyendranath Bose) at temperatures that were present in the universe at all epochs. Motivated by the model’s potential to resolve the Big Bang singularity and account for dark matter and dark energy, the physicists plan to analyze their model more rigorously in the future. Their future work includes redoing their study while taking into account small inhomogeneous and anisotropic perturbations, but they do not expect small perturbations to significantly affect the results.”It is satisfying to note that such straightforward corrections can potentially resolve so many issues at once,” Das said. (Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein’s theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once. Explore further The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a “Big Bang” did the universe officially begin.Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after—not at or before—the singularity. “The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there,” Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology, both in Egypt, told Phys.org.Ali and coauthor Saurya Das at the University of Lethbridge in Alberta, Canada, have shown in a paper published in Physics Letters B that the Big Bang singularity can be resolved by their new model in which the universe has no beginning and no end. Old ideas revisitedThe physicists emphasize that their quantum correction terms are not applied ad hoc in an attempt to specifically eliminate the Big Bang singularity. Their work is based on ideas by the theoretical physicist David Bohm, who is also known for his contributions to the philosophy of physics. Starting in the 1950s, Bohm explored replacing classical geodesics (the shortest path between two points on a curved surface) with quantum trajectories. In their paper, Ali and Das applied these Bohmian trajectories to an equation developed in the 1950s by physicist Amal Kumar Raychaudhuri at Presidency University in Kolkata, India. Raychaudhuri was also Das’s teacher when he was an undergraduate student of that institution in the ’90s. Using the quantum-corrected Raychaudhuri equation, Ali and Das derived quantum-corrected Friedmann equations, which describe the expansion and evolution of universe (including the Big Bang) within the context of general relativity. Although it’s not a true theory of quantum gravity, the model does contain elements from both quantum theory and general relativity. Ali and Das also expect their results to hold even if and when a full theory of quantum gravity is formulated.

© 2015 Phys.org At the bottom of the 2 meter deep pit, the researchers report, were the scattered pieces and bits of hand bones, along with seven human arms, all from the left side of the body. On top of those were piled the full skeletal remains of one woman, two men and four children. Just one of the skeletons had an arm missing—one of the males, but it was not yet known if one of the arms underneath was his. The condition of the skeletons, the team suggests, indicates that the bones once belonged to people who were killed in some type of warfare—there was damage that appeared inflicted by axes or other such implements. Testing of the bones indicated they were all from a period between 5,500 and 6,500 years ago, putting them in the Neolithic period. A layer of sediment was on top of the skeletons and on top of that was the skeleton of another woman, whose body had clearly been put there long after the bones underneath.The team notes that there was also a piece of jewelry among the skeletons, an arrowhead, a pig jaw bone and the skeletons of two hares, which the group notes, might have simply fallen in the pit and died because they could not jump out.

The researchers suggest the severed arms might have been part of a trophy collection, though they note that it would represent the first evidence of such a practice for the people of that time period. Taken together, the evidence rules out the placement of the arm bones and skeletal remains as part of a funerary process, they add. More information: Fanny Chenal et al.

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. The researchers, led by Arseniy Kuznetsov and Ramón Paniagua-Domínguez, at A*STAR (Agency for Science, Technology, and Research) and Nanyang Technological University, both in Singapore, have published a paper on the lens with near-unity numerical aperture in a recent issue of Nano Letters.Previously, the highest numerical aperture for a free-space lens was 0.95, which corresponds to a maximum collection angle of around 72°. Due to the way these lenses are made, they are also large and expensive, and so cannot be easily scaled down to work with very small systems.With its numerical aperture of 0.99, the new lens has both a higher resolution and a larger collection angle of 82°. The new lens is made of a metasurface rather than traditional lens materials. The metasurface consists of a pattern of subwavelength-scale structures and has an overall thickness of less than one wavelength of light, resulting in a small size that greatly expands its potential applications.”High-numerical aperture lenses/microscope objectives are major optical components that are widely used in microscopy, optical detection systems, optical lithography, quantum optics, etc.,” Kuznetsov told Phys.org. “Having a high numerical aperture is of primary importance in achieving a high resolution and high detection level of optical signals. Currently existing high-numerical-aperture lenses/microscope objectives are bulky and expensive. In this work, we showed that, using a new concept of metasurfaces based on dielectric nanoantennas, it is possible to design and realize flat optical components that can achieve a numerical aperture higher than all existing optical objectives, using just a device just a few hundred nanometers thick.”To demonstrate the advantages of the new lens, the researchers used it to image nitrogen-vacancy centers in diamond nanocrystals, which are several tens of nanometers in size. The images scanned by the new metalens revealed smaller spots compared to images scanned using commercial lenses with smaller numerical apertures, demonstrating the new lens’ higher resolution.The researchers expect that, in the future, the new lens may also be used to make improvements to photolithography, which is used to produce computer chips and other high-resolution devices. In addition, the new lens’ wide-angle collection is expected to increase the efficiency of single-photon emission processes, which are used in quantum optics systems.”We believe that this new concept will find broad applications in areas where detection of weak optical signals is important,” Kuznetsov said. “One example is in quantum optics, which deals with systems containing only single atoms or quantum emitters emitting light at the single-photon level. Such flat lenses not only allow for the detection of weak optical signals, but also can operate at extreme conditions of low temperatures and in vacuum, which is typical for quantum optics experiments.”Another important application direction could be in wearable and mobile photonic devices, where dense integration of high-efficiency optical components is required. For example, the lenses could find applications in mobile phone cameras and augmented reality glasses.” Nanostructured thin-films that can bend light by large angles could be a replacement for bulky glass optical components Explore further More information: Ramón Paniagua-Domínguez et al. “A Metalens with a Near-Unity Numerical Aperture.” Nano Letters 18, 2124–2132 (2018). DOI: 10.1021/acs.nanolett.8b00368 Researchers have designed an optical lens with the highest free-space numerical aperture to date, achieving a value of just under 1. As the numerical aperture indicates the highest possible resolution that a lens can attain, the new lens can focus light with unprecedented ability, as well as collect light from wide angles. These abilities should make the lens particularly useful for low-light applications, such as single-photon emission, which is often used in quantum optics systems.

A team of researchers with Purdue University has demonstrated the highest reported conductivity for an organic radical polymer to date, moving another step closer to their use in electronics. In their paper published in the journal Science, the group describes the technique they used and offer an opinion on why it produced the results they found. Jodie Lutkenhaus, with Texas A&M University writes a Perspectives piece on the work done by the team in the same journal issue, and discusses further possible research in the area. © 2018 Phys.org More information: Yongho Joo et al. A nonconjugated radical polymer glass with high electrical conductivity, Science (2018). DOI: 10.1126/science.aao7287AbstractSolid-state conducting polymers usually have highly conjugated macromolecular backbones and require intentional doping in order to achieve high electrical conductivities. Conversely, single-component, charge-neutral macromolecules could be synthetically simpler and have improved processibility and ambient stability. We show that poly(4-glycidyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl), a nonconjugated radical polymer with a subambient glass transition temperature, underwent rapid solid-state charge transfer reactions and had an electrical conductivity of up to 28 siemens per meter over channel lengths up to 0.6 micrometers. The charge transport through the radical polymer film was enabled with thermal annealing at 80°C, which allowed for the formation of a percolating network of open-shell sites in electronic communication with one another. The electrical conductivity was not enhanced by intentional doping, and thin films of this material showed high optical transparency.

As Lutkenhaus notes, organic radical polymers (ORPs), flexible plastics, have properties that could make them suitable for use in a wide variety of applications, such as battery storage, electronics and memory devices. But that requires a technique to make them run faster. ORPs are made up of a hydrocarbon backbone and radical function groups that hang off of them like bulbs on a string of Christmas lights. Currently, they are used mainly in batteries, and perform almost like capacitors. This is because they work as conjugated polymers—charges move along the backbone due to electronic delocalization. In this new effort, the researchers took a new approach that they believe allows the charge to move directly between the radical function groups, which produces much faster movement.The researchers started with traditional strands of PTEO ORPs, which they refer to as random coils. In such a configuration, they note, the radical groups were initially too far apart to carry a charge very far. To bring them closer together, the team applied thermal annealing (heating them and then allowing them to cool). Doing so, they report, caused a dramatic speed-up of the charge when it was applied. The team does not yet know for certain why, but they have a theory. They believe the annealing process caused different parts of the strand making up the coil to bend closer to one another, bringing them close enough together so that the radical groups from both parts of the strand could share electron transport.The work represents a step toward using ORPs in electronics, though there is one major obstacle yet to overcome—the technique only works for very short distances. To be used in applications other than batteries, ORPs will need to carry a charge much farther.

The Syrian Observatory for Human Rights, a monitoring group, said the strikes were on an office and a vehicle in Idlib province in northwest Syria, where last week the group routed Western-backed Syrian rebels.Residents said one strike targeted a car used by Nusra commanders, near an internet cafe in the Nusra-controlled town of Sarmada close to the Turkish border.A rebel from another Western-backed group operating in northern Syria confirmed the air strikes on the Nusra Front and hardline Islamist group Ahrar al-Sham near the border with Turkey, and said they took place at around 1 a.m.‘The strength of strikes and their accuracy confirms that they were carried out by the alliance,’ the rebel said, speaking on condition of anonymity.The Nusra Front vehicle struck in the attack had been carrying ammunition, he said. In neighbouring Harem, residents said at least four children had been killed and dozens injured in an attack they believed was launched by the coalition.The Observatory also reported the first air strikes against Ahrar al-Sham.Residents around the rebel-held Bab al-Hawa border crossing, a strategic gateway to Turkey, said a missile flattened the group’s headquarters nearby and killed Abu al-Nasr, the head of its arms procurement division.Rami Abdulrahman, head of the Observatory, said it marked the second time the Nusra Front had been hit in the U.S.-led campaign. The first was on Sept. 23, the first day of U.S. air strikes in Syria, which are part of Washington’s strategy to ‘degrade and destroy’ Islamic State.Nusra, which has been trying with allies to remove its name from the U.N. terrorist list, was taken by surprise when coalition warplanes bombed several of its positions then. Several commanders are believed to have been killed in the September strikes, including Kuwaiti-born Mohsin al-Fadhli — also known as Abu Asmaa al-Jazrawi — reputedly a former member of Osama bin Laden’s inner circle.Nusra Front last week seized control of areas of Idlib province from Western-backed rebel leader Jamal Maarouf, head of the Syria Revolutionaries’ Front in northern Syria, confiscating its weapons.
