New Theory of the Universe Marries Two of its Biggest Mysteries

first_img Improved model could help scientists better predict crop yield, climate change effects Physicists have devised a theory that unifies two widely studied mysteries of the universe: why there is an imbalance between regular matter and anti-matter (scientists expect to see equal amounts of each, but observe less anti-matter), and the identity of “dark matter” – the enigmatic particles thought to account for the extra gravitational pull observed in distant galaxies. He and his colleagues show in their paper (which appears in the November edition of the Journal of High Energy Physics) that if the dark-matter particle has certain properties it would have interacted with regular matter. When added to the rest of the equations in the Standard Model (dark matter is not currently part of it), this interaction could have caused a preference for matter over antimatter. Like the sphaleron process, this interaction would only take place at the very high temperatures of the early universe and would “turn off” as the universe cooled down. This not only explains how more baryons than anti-baryons could be generated momentarily, but also why there would be more baryons in the long run. But for this to work, the sphaleron process would have to turn off before the dark matter/regular matter interaction did. If it occurred in the opposite order, the excess baryons in the early universe would be annihilated by the new anti-baryons produced by the sphaleron process.The group came up with these ideas as they were studying an extension of the Standard Model known as the Pentagon model, which involves theoretical particles dubbed pentaquarks, which tend to combine together in groups of five. Scientists can only verify the Standard Model for particles with energies achievable in man-made experiments, which, relatively, are not very high. At high energies, many scientists suspect that the Standard Model breaks down and there is new physics at play. The Pentagon model, on the other hand, leaves room for unknown forces and holds at energies in which the Standard Model fails.The researchers say that their theory of baryogenesis could still be valid if the Pentagon model turns out to be incorrect, provided that their assumptions about the identity and nature of dark matter are true.“Ultimately, in order to know whether our theory is really the right explanation, it will need to be tested. Because it involves connections between many different kinds of physical processes, there will be more opportunities to test it and this may in some ways make it easier to test,” says Jones. “However, it has a certain advantage over alternatives in that it manages to kill two birds with one stone.”Citation: Tom Banks, Sean Echols and Jeff L.

Protons and neutrons are the most common examples of baryons. By extension, ordinary matter – atoms, in other words, which are primarily protons and neutrons – is therefore essentially made of baryons. Similarly, anti-matter is mostly anti-baryons.The Russian physicist Andrei Sakharov, father of the Russian hydrogen bomb and advocate of peaceful coexistence between the Soviet and western systems, pointed out in the 1960s that in order for baryogenesis to take place there had to be a violation of CP symmetry.” CP symmetry is a physics concept stating that if ordinary particles are replaced by anti-particles in any physical process, and the particles’ “handedness” is simultaneously reversed (sort of like how I’m right-handed but my mirror image, my “anti-self,” is a lefty), the result should be an equally feasible process occurring at the same rate as the first. Of the four known fundamental forces – strong, weak, electromagnetic, and gravity – scientists have only seen the weak force violate CP symmetry in experiments. However, when that violation results in the production of baryons, it also always generates anti-baryons. So there is no imbalance produced.There must be, then, a process that does not conserve the total number of baryons involved and also violates CP symmetry. The Standard Model of particle physics – a theory describing the relationship between the strong, weak, and electromagnetic forces, and the particles that feel those forces – predicts that there is such a process. Known as the sphaleron process, it would only take place at temperatures far too high to achieve in a lab, but would have existed during the early universe. The sphaleron process allows for the possibility of matter being generated without the corresponding anti-matter, but it’s still not a complete solution. But, Jones says, “The universe had no reason to prefer matter over anti-matter, so in the long run you would expect it to eventually even out. Mysteriously, it hasn’t, and that’s where our work comes in.”last_img read more

Electronic tattoo display runs on blood

first_img Explore further Look beyond the sun for skin cancer culprits, doctors warn Jim Mielke’s wireless blood-fueled display is a true merging of technology and body art. At the recent Greener Gadgets Design Competition, the engineer demonstrated a subcutaneously implanted touch-screen that operates as a cell phone display, with the potential for 3G video calls that are visible just underneath the skin.

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 tattoo display: “Waterproof and powered by pizza.” The basis of the 2×4-inch “Digital Tattoo Interface” is a Bluetooth device made of thin, flexible silicon and silicone. It´s inserted through a small incision as a tightly rolled tube, and then it unfurls beneath the skin to align between skin and muscle. Through the same incision, two small tubes on the device are attached to an artery and a vein to allow the blood to flow to a coin-sized blood fuel cell that converts glucose and oxygen to electricity. After blood flows in from the artery to the fuel cell, it flows out again through the vein.On both the top and bottom surfaces of the display is a matching matrix of field-producing pixels. The top surface also enables touch-screen control through the skin. Instead of ink, the display uses tiny microscopic spheres, somewhat similar to tattoo ink. A field-sensitive material in the spheres changes their color from clear to black, aligned with the matrix fields.The tattoo display communicates wirelessly to other Bluetooth devices – both in the outside world and within the same body. Although the device is always on (as long as your blood´s flowing), the display can be turned off and on by pushing a small dot on the skin. When the phone rings, for example, an individual turns the display on, and “the tattoo comes to life as a digital video of the caller,” Mielke explains. When the call ends, the tattoo disappears.Could such an invasive device have harmful biological effects? Actually, the device could offer health benefits. That´s because it also continually monitors for many blood disorders, alerting the person of a health problem.The tattoo display is still just a concept, with no word on plans for commercialization.core77.com via Gizmodo last_img read more

Cool under pressure Superconductivity in 3D Dirac semimetal zirconium pentatelluride

first_imgThe paper reported that the possibility of topological superconductivity at higher pressure cannot be excluded, and so remains an open question, as well as while the researchers’ theoretical study rules out the possibility of topological superconductivity at low pressure, at high pressure (above 20 GPa), the system has a complicated Fermi surface and a superconducting phase. “Of major interest in the field of topological superconductivity is the realization of Majorana fermions, which are predicted to exist as protected bound states in topological superconductors,” Sun explains. “In contrast to most of the above-mentioned topologically-related states, which have been theoretically predicted and experimentally proven, topological superconductivity remains elusive.” However, Yang continues, the Dirac semimetal is the neighbor state closely related to various quantum states ranging from topological insulators to topological superconductors. “This versatility makes the Dirac semimetal an ideal parent compound for the realization of topological superconductivity. Moreover, in order to study the nature of superconductivity, we further performed band structure and Fermi surface calculations at high pressures, and showed that the possibility of topological superconductor at higher pressure cannot be excluded, which deserves further investigations.”Looking ahead, the scientists are planning to study the pressure-induced topological transition with the help of high magnetic fields and ultra-low temperature. “Currently, we’re developing an integrated system which combines the extreme conditions of high pressure, high magnetic field (up to 35 T) and ultra-low temperature (0.3 K), so that we can explore the Fermi surface structures by probing the quantum oscillations of the normal state under high pressure.”As to other areas of research, Yang tells Phys.org, the researchers believe that their study will be beneficial to material science – particularly for synthesizing novel superconducting materials. © 2016 Phys.org Prof. Zhaorong Yang and Phys.org discussed the paper he and his colleagues published in Proceedings of the National Academy of Sciences, in which they report their discovery of the pressure-induced transition of the three-dimensional Dirac semimetal zirconium pentatelluride (ZrTe5) to a superconductor by combining synchrotron X-ray diffraction, magnetic field low-temperature transport and theoretical investigations. “Three-dimensional Dirac semimetals are neighbor states to other exotic phases such as topological insulators, Dirac semimetals, Weyl semimetals, superconductors, and even topological superconductors,” Yang tells Phys.org. “Recent theoretical and experimental studies show that ZrTe5 is a very promising system that hosts topological properties and might help to pave a new way for further experimental studies of topological phase transitions.” These discoveries spark the present team of scientists’ interests to further investigations on its Dirac and topological characters in ZrTe5 under high pressures, since pressure has proven to be an effective method for tuning electronic properties of materials by extensive studies.Prof. Jian Sun (an author of the paper discussed in this article) notes that “The sample is small, experiments are performed under extreme conditions and the signals are not strong. So it is very difficult to determine the crystal structures of high pressure phases based on the experimental data only. Our theoretical crystal structure prediction technique provides us the best candidates under the experimental circumstances and can be compared with the measured signals to eventually nail down the real structures.””We first conducted resistance and AC magnetic susceptibility measurements on ZrTe5 single crystals at various pressures up to 68.5 gigapascals and observed two superconducting phases,” Yang adds. One gigapascal (GPa) is equivalent to 1,000,000,000 pascals (Pa) – the standard unit of pressure defined as one newton per square meter. “However, we noticed that the constructed pressure-superconducting phase diagram is very similar to that of tellurium, possibly due to the decomposition of ZrTe5 under high pressure.” To determine the origin of this transition, the researchers carried out in situ high-pressure synchrotron X-ray diffraction and Raman spectroscopy measurements combined with theoretical calculations. “We’re very lucky that both experimental measurements and theoretical calculations identified that the superconducting phases are coming from a two-stage structural phase transition.” Journal information: Proceedings of the National Academy of Sciences The scientists found that (1) the appearance of superconductivity at the critical pressure is accompanied by the complete suppression of the high temperature resistance anomaly around 128 K, showing a structural transition from the Cmcm to C2/m space group, and (2) that at pressures above 21.2 GPa, a second superconducting phase with P-1 space group structure manifests and coexists with the original C2/m. (In mathematics and physics, a space group is the symmetry group of a configuration in space, usually in three dimensions.) “The superconductivity often appears in compounds which are close to a structural, magnetic, or electronic instability. More recent investigations have revealed that the high temperature resistance anomaly around 128 K is caused by temperature induced Lifshitz transition, in which the Fermi surface undergoes a change in topology and a drastic change in the electronic density of states.” In their study, the team demonstrated that the appearance of superconductivity at the critical pressure is accompanied by the complete suppression of the resistance anomaly and a structural transition indicates that both electronic and structural instabilities are responsible for the observed superconductivity.

Astronomers discover a large cavity around the Tychos supernova

first_imgChinese astronomers have detected a large cavity existing around Tycho’s supernova, also know as SN 1572, exhibiting stream-like structures.

It is a well-established type Ia supernova, one of about eight supernovae visible to the naked eye in historical records. As one of the most popular supernova remnants in our galaxy, it has been widely observed in the entire electromagnetic spectrum, and astronomers have discovered a shell-like structure produced by the shocks from the explosion as well as circumstellar material and dust.More recent observations of Tycho’s supernova were conducted by a team of Chinese astronomers led by Xuepeng Chen of the Purple Mountain Observatory (PMO) in Nanjing, China. They used the 13.7-meter millimeter-wavelength telescope of the Qinghai station of PMO at Delingha in China to perform large-field and high-sensitivity carbon monoxide (CO) molecular line observations of SN 1572. The scientists observed the supernova from November 2011 to February 2016 as part of the Milky Way Imaging Scroll Painting (MWISP) survey, which investigates the nature of the molecular gas along the northern Galactic Plane.”We present large-field CO (1-0) molecular line observations toward the Tycho’s supernova remnant, using the PMO 13.7-meter telescope. Based on the CO observations, we find a large cavity with radii of 0.3 degrees by 0.6 degrees around the remnant, which is further confirmed by the complementary infrared images from the space telescopes,” the researchers wrote in the paper.The team estimated that the cavity is located about 8,000 light years away and has radii of 42 and 88 light years. Their calculations allowed them to estimate that this cavity is expanding at a velocity of approximately 4 km s-1.Moreover, the astronomers distinguished stream-like structures in the cavity that could be part of a larger cavity seen along the line of sight. They noted that these structures may also record the accretion winds from the progenitor system. Due to these uncertainties, the team calls for further observations that could illuminate the real nature of these structures.”In the wind-regulated accretion models, the accretion wind could last for few million years, and the white dwarf may explode as a type Ia supernova while the accretion wind is still active. Therefore, another possible explanation is that these stream-like structures actually record the accretion winds from the progenitor system. This scenario is somehow supported by the infrared observations, in which knot-like structures are also found in the southwest and west of the cavity,” the paper reads.The scientists also investigated the origin of the cavity. They excluded the possibility that it could be produced by bright star in the region or the option that it was randomly distributed. According to the paper, the most plausible hypothesis taken into account is that it could be explained by the accretion wind from the progenitor system of the Tycho’s supernova.”The discovery of the Tycho’s cavity also gives us an alert that the environments of the supernovae Ia may be much more complicated than we thought before,” the researchers concluded.

More information: Discovery of A Large Cavity around the Tycho’s Supernova Remnant, arXiv:1608.05329 [astro-ph.GA] arxiv.org/abs/1608.05329AbstractWe present large-field (3×2 deg^2) and high-sensitivity CO(1-0) molecular line observations toward the Tycho’s supernova remnant, using the 13.7-meter radio telescope of the Purple Mountain Observatory. Based on the CO observations, we discover a large cavity around the remnant, with radii of about 0.3×0.6 deg (or ~13×27 pc at a distance of 2.5 kpc), which is further supported by the complementary infrared images from the space telescopes. The observed CO line broadenings and asymmetries in the surrounding clouds, the infrared pillar-like structures found around the remnant, in concert with enhanced 12CO(2-1)/(1-0) intensity ratio detected in previous studies, indicate strong interaction of the large cavity with a wind in the region. After excluding the scenario of a large bubble produced by bright massive stars, we consider that the large cavity could be most likely explained by the accretion wind from the progenitor system of the Tycho’s supernova. The CO gas kinematics indicates that the large cavity is expanding at a velocity of about 4 km/s. The estimated velocity (~1000 km/s, with a mass-loss rate of ~10^(-6)*M_sun*yr^(-1)) and timescale (~4×10^6 yr) of the wind needed for creating such a cavity are consistent with the predictions from the wind-regulated accretion model. We conclude that Tycho’s supernova, the prototypical Type-Ia supernova in the Milky Way, arose from accretion onto a white dwarf.last_img read more

HMC set to introduce online property tax payment from second week of

first_imgKolkata: Howrah Municipal Corporation (HMC) is all set to introduce the system of online payment of property tax from the second week of May.The days of standing in long queues to pay property tax is going to be a matter of the past, with introduction of the online mechanism.Dr Rathin Chakraborty, Mayor, said: “The initiative is a part of the measures taken to provide better civic amenities to the residents of Howrah.”At present, residents of the area under the municipal corporation have to visit the headquarters of the civic body to pay their property tax. But with introduction of the online system, using which one can pay the same from their mobile phones itself, the process is going to become much easier. Also Read – Heavy rain hits traffic, flightsIn a bid to make the payment online, one has to visit the website of the municipal corporation, which is www.hmcgov.in. There will be a link available in the website and just a click on the link will take the user to the page, through which the property tax can be paid online.Bijin Krishna, commissioner of Howrah Municipal Corporation, said: “The work to introduce the online platform to pay property tax is almost complete and it will be introduced soon in May.” Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedBesides introducing the online platform to pay the property tax, the civic body is also ensuring that one can make the payment at borough offices as well. The step has been taken so that people who are not that comfortable in making the payment online, do not have to travel a long distance up to the headquarters to pay their property tax. Instead, they can make the payment at borough offices as well.It has been learnt that in absence of the online platform to pay the property tax, the civic body authorities at present release the bill for the same in phases, to avoid unnecessary gathering at the payment receiving counter. In a bid to make the people aware of the new system, the HMC authorities will be sending a notice along with the next property tax bill.last_img read more

Moves that sweep you off your feet

first_imgExpression of feelings and complex emotions is best done through dance, which is not only limited to the boundaries of an art form but outshines the limited approach of words. In an attempt to showcase a dance performed on the beats of amalgamated carnatic music and classical Hindustan music, ‘Aayam Cultural Society’, Art Culture & Languages, Government of Delhi is organising a Bharatnatyam dance recital. Shashrek Ambardar, disciple of Sindhu Mishra will be performing in the national Capital. Also Read – ‘Playing Jojo was emotionally exhausting’The event will be inaugurated by Kapil Mishra, Minister of Art, Culture & Languages, Government of Delhi. With its vivid expression of emotions, its sculpturesque poses and the rhythmic depiction of innate human feelings, Bharatnatyam has been one of India’s most loved classical dance forms that have retained its popularity over centuries and spread its following to even distant lands.Presented by Aayam Cultural Society, choreographed by renowned danseuse Sindhu Mishra, recital has attempted a unique synthesis between Carnatic and Hindustani music styles. Also Read – Leslie doing new comedy special with NetflixThis January, ‘Aayam,’ the society for promotion of Indian culture, is presenting a never-seen-before performance of Bharatnatyam that blends the seamless singing of Hindustani classical music with the rhythmic elements of Carnatic music to attempt a new take on the traditional south Indian dance form.Choreographed by veteran danseuse and actor Sindhu Mishra, and performed solo by her young and dynamic disciple Shashrek Ambardar, the recital is in Hindi and offers a unique synthesis between two different musical forms. Padma Vibhushan Dr Sonal Mansingh will grace the occasion as a special guest. The performance will also be attended by other veteran artists including Padma Bhushan Raja Reddy; Padmashri Pt Bhajan Sopori and Padmashri Bharti Shivaji as guests of Honour. Explaining the unique features of the dance recital, Sindhu Mishra says that she and her team have worked tremendously hard on this recital to offer something different and enchanting to the lovers of Indian classical dances. “This recital is different for its unique amalgamation of Hindustani and Carnatic music not just in rhythms but also in vocals. The vocal renditions are in both Hindustani and Carnatic, and this lends a unique blend to the traditional south Indian dance form. Unlike most Bharatnatyam recitals which are performed by women, this is a solo performance by a male dancer. The entire Varnam displays the Sringar Ras of the Nayak (and not the Nayaki), depicted through the episode where Rama has a glimpse of Sita for the first time in a garden before the Dhanush Yagya,” she says. Bharatnatyam is based on episodes from Tulsidas’s Ramacharitmanas, one of the most loved epics of Indian literature, a poetic retelling of Valmiki’s Ramayana. It was Tulsidas’s epic that successfully took the Ramayana’s understanding from a select elite to the common masses by narrating it in their language.Currently studying Economics at St. Stephen’s College, Delhi University, Shashrek said, “I feel honoured to perform at a prestigious stage in front of some of India’s most veteran artists as well as the discerning audience of Delhi. We are hopeful that this unique experiment will be loved and appreciated by the people. I thank our troupe and my guru for giving me this opportunity.” When: January 15Where: LTG Auditorium, Mandi HouseTimings: 6pmlast_img read more

TMC block president shot at health condition critical

first_imgOur correspondent Kolkata: A block president of Trinamool Congress was shot at by some unidentified miscreants when he was returning home on Sunday afternoon. The incident took place in Khairasol area of Birbhum when some miscreants fired indiscriminately at him. The victim, Deepak Ghosh, has received two bullet injuries in his body. He was immediately rushed to Durgapur Mission Hospital. According to hospital sources, the health condition of the victim is stated to be critical. Also Read – Rain batters Kolkata, cripples normal lifeThe district Trinamool Congress leaders have alleged that the BJP backed miscreants were behind the attack and demanded a high level probe into the incident. The district BJP leaders have, however, denied the allegation and termed this to be a result of the intra-party clash within Trinamool Congress. Ghosh, an active Trinamool Congress leader, has been instrumental in strengthening the party’s organisation in the district. It might be an attempt to weaken the organisation, alleged senior Trinamool Congress leaders. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedGhosh was returning home on a motorcycle on Sunday afternoon when some miscreants blocked his way and shot at him from a close quarter. Two bullets pierced his body and the victim fell on the ground. Alerted by the sound of gun shots, locals rushed to his rescue. The miscreants who reportedly came on motorcycles fled the spot immediately after the incident. After being informed police reached the spot and started a probe in this regard. Police are conducting raids to nab the culprits. It may be stated that Ghosh was attacked earlier as well by some miscreants. Anubrata Mondal, Trinamool Congress president in Birbhum on Sunday said Ghosh is an efficient organiser who had contributed immensely in the party organisation. It was a deliberate attempt to weaken the organisation, Mondal said. He also alleged that the BJP backed goons were behind the attack.last_img read more

Officiating commandant and second in command of BSF’s 199 Battalion, D K Singh who had chaired the programme, said: “The principal objective of arranging such programmes is to provide a sense of security amongst border people. Our Battalion organises similar programmes frequently. Today’s Civic Action Programme helps to enhance overall basic standard of living and the little school goers’ education.” Notably, the border population is being an important stakeholder in the entire process of border management. “It is also pertinent that they should be taken along in the development process,” Singh said. It is true that the border people have been residing with tremendous financial crunch and compulsions following which they urgently need economic support. The Mamata Banerjee government has already undertaken many benevolent tasks extending their aid and support.last_img read more
