Citation: Battery embedded in circuit board demonstrated at Tokyo exhibition (2010, June 6) retrieved 18 August 2019 from Panasonic Starts Mass-Production of High-Capacity 3.1 Ah Lithium-ion Battery More information: via: Tech-On and The Green Optimistic So far, there have been only a few circuit boards that have come with integrated energy devices. For instance, some circuit boards in mobile phones have embedded double layer capacitors to store energy, but these capacitors tend to have problems with high leak currents that increase the number of charges and drain the battery faster than normal. On the other hand, embedding the entire battery into a circuit board makes it possible to reduce leak currents and the number of charges, as well as reduce the peak power of the system. Oki Printed Circuits’ embedded thin-film battery, which is a product of Infinite Power Solutions, has an output voltage of 4.2V and a 0.7mAh capacity. With these parameters, the device could turn an LED lamp off and on, as demonstrated at the exhibition. If the battery’s power can be scaled up in the future, it might also be used to power other electronic devices.An article at The Green Optimistic mentions another potential future application of embedded batteries: “Electric cars could also benefit from an embedded battery that is spread all over the vehicle in independent modules that could power various parts of the car. When they break, the embedded batteries would also be changed easily and cheaper than if a total replacement of a unique and bigger battery would be needed.”Oki Printed Circuits plans to expand the applications of the technology with several corporate partners, and hopes to commercialize the device in 2011.

Critics raise doubts on NASAs arsenic bacteria

first_img Explore further A microscopic image of GFAJ-1 grown on arsenic. The findings reported last week, were that some bacteria (GFAJ-1) thrived when access to phosphate was removed and the bacteria were grown in a highly toxic culture rich is arsenate. The scientists suggested the bacteria thrived because they were able to replace phosphorus, which has always been thought vital to life, with arsenic, which is directly under it on the periodic table and has similar chemical properties. The researchers also suggested the bacteria were replacing phosphorus with arsenic within the bases that make up DNA. These findings, if correct, would mean the scientists had found a new form of life on Earth, and it would also re-write the guide book on the essential requirements for life to exist elsewhere.After the findings were published in Science, other scientists began immediately to express their doubts at the conclusions of the paper, with some even expressing the opinion the paper should not have been published at all. One of the critics was Dr. Alex Bradley, from Harvard University, who blogged that there were a number of problems with the research. Firstly, if arsenic had replaced phosphorus in the DNA the molecule would have broken into fragments when the DNA was placed in water, since the arsenic would have hydrolyzed, and yet it did not. Secondly, the paper showed there was a small amount of phosphorus in the medium and Bradley argued that even though small, this could have been enough, since bacteria metabolism is extremely efficient. Dr. Bradley also pointed out the bacteria live in Mono Lake, which is rich in arsenic but which also contains a higher concentration of phosphate than almost anywhere else on Earth, and this means there would be no selective pressure for a life based on arsenic to evolve. Dr. Bradley also suggested a mass spectrum of the DNA sequences would have shown whether or not the nucleotides contained arsenic in place of phosphorus, but this was not done.Another critic was University of British Columbia biologist Rosie Redfield, who reviewed the paper on her blog, and has more recently submitted a letter to the journal. Among her conclusions are that the paper “doesn’t present ANY convincing evidence that arsenic has been incorporated into DNA (or any other biological molecule).” She also writes: “If this data was presented by a PhD student at their committee meeting, I’d send them back to the bench to do more cleanup and controls.”Dr. Redfield also points out there was phosphate in the culture and that the authors did not calculate whether the amount of growth they saw in the arsenate-only medium could be supported by the phosphate present. She calculates on the blog that the growth of the bacteria is actually limited by the amount of phosphorus.Another point made by Redfield is that the arsenic bacteria were “like plump little corn kernels” and contain granules, which are usually produced by bacteria when they have ample supplies of carbon and energy sources but there are shortages of other nutrients needed for growth.The authors of the arsenic bacteria paper initially refused to be drawn into the arguments, saying the discussion should be confined to peer-reviewed journals, but one of the authors, Ronald Ormeland, did answer questions on the controversy after giving a lecture on the findings at NASA headquarters yesterday. He said the amount of phosphorus in the sample was too small to sustain growth, and a mass spectrum was not done because they did not have enough money, and wanted to get the result published quickly. He also pointed out that the bacteria are still there and other scientists could duplicate the work and carry out further experiments if they wished. ( — NASA’s announcement last week that bacteria had been discovered that appeared to replace phosphorus with arsenic and thrive even in the most poisonous environments, has now come under fire from a number of scientists.

Chemists devise means to use bacteria to encode secret messages

Theoretical physicists offer explanation of how bacteria might generate radio waves More information: InfoBiology by printed arrays of microorganism colonies for timed and on-demand release of messages, PNAS, Published online before print September 26, 2011, doi:10.1073/pnas.1109554108AbstractThis paper presents a proof-of-principle method, called InfoBiology, to write and encode data using arrays of genetically engineered strains of Escherichia coli with fluorescent proteins (FPs) as phenotypic markers. In InfoBiology, we encode, send, and release information using living organisms as carriers of data. Genetically engineered systems offer exquisite control of both genotype and phenotype. Living systems also offer the possibility for timed release of information as phenotypic features can take hours or days to develop. We use growth media and chemically induced gene expression as cipher keys or “biociphers” to develop encoded messages. The messages, called Steganography by Printed Arrays of Microbes (SPAM), consist of a matrix of spots generated by seven strains of E. coli, with each strain expressing a different FP. The coding scheme for these arrays relies on strings of paired, septenary digits, where each pair represents an alphanumeric character. In addition, the photophysical properties of the FPs offer another method for ciphering messages. Unique combinations of excited and emitted wavelengths generate distinct fluorescent patterns from the Steganography by Printed Arrays of Microbes (SPAM). This paper shows a new form of steganography based on information from engineered living systems. The combination of bio- and “photociphers” along with controlled timed-release exemplify the capabilities of InfoBiology, which could enable biometrics, communication through compromised channels, easy-to-read barcoding of biological products, or provide a deterrent to counterfeiting. Explore further © 2011 Called Steganography by Printed Arrays of Microbes (SPAM), the process is pretty simple. The team first developed seven different strains of the E. coli bacteria that grow in different colors (when bathed in ultraviolet light). They then devised a simple coding scheme based on pairings of the colors to represent letters of the alphabet (and some symbols). Next, they applied the bacteria to a plate of agar (a gelatinous substance that serves as food for the bacteria) where they grew into their respective color types. Next, a sheet of a nitrocellulose type material (that looks pretty much like paper) was pressed over the plate of agar, imprinting it with the bacteria. The result was then dried, causing the coloring attribute to disappear, making it ready for possible placement into an envelope for posting. After some time passed, the paper-like material was pressed onto an agar plate and the bacteria grew once again into their coloring, revealing the coded message.The process is so simple in fact, that it’s a wonder that no one thought to do it until now. Other means for encoding messages, such as stamping them into DNA, are in comparison much more complicated and expensive. The downside to this method of course, is that if someone wishes to intercept the message, it wouldn’t be all that hard to decode the message if they knew that it was bacteria encoded. To get around this problem, the team added fluorescence to antibiotic resistant genes so that the message would only become visible when ampicillin, for example, was introduced. Thus, the would-be snooper would not only need to know which method of coding was used, e.g. bacterial, they’d also have to know which antibiotic to use to reveal the right message. Message makers could even encode a false message for those using the wrong antibiotic.The authors also note that other factors could be engineered into their process as well, such as setting the bacteria to grow at certain times, or to die at others so the message won’t last long. Also, other types of nutrients that are maybe a little harder to find could be used re-grow the bacteria.Also, while such technology has obvious applications in espionage, other uses might be to watermark certain organic material or organisms to prevent counterfeiting. Citation: Chemists devise means to use bacteria to encode secret messages (2011, September 27) retrieved 18 August 2019 from ( — In the endless search to develop newer and cooler ways to send messages between people without other’s intercepting them, chemists from Tufts University working together have figured out a way to use a strain of bacteria to encode a message on a paper-like material that can then later be de-coded by the receiver. Manuel Palacios and David Walta, along with their team describe in their paper published in the Proceedings of the National Academy of Sciences, how they did it.last_img read more

NIF facility fires record laser shot into target chamber

first_img More information: The National Ignition Facility (NIF): official announcement is below:The National Ignition Facility (NIF), the world’s most energetic laser, surpassed a critical milestone in its efforts to meet one of modern science’s greatest challenges: achieving fusion ignition and energy gain in a laboratory setting. NIF’s 192 lasers fired in perfect unison, delivering a record 1.875 million joules (MJ) of ultraviolet laser light to the facility’s target chamber center.This historic laser shot involved a shaped pulse of energy 23 billionths of a second long that generated 411 trillion watts (TW) of peak power (1,000 times more than the United States uses at any instant in time).The record-breaking shot was made March 15.”This event marks a key milestone in the National Ignition Campaign’s drive toward fusion ignition,” said NIF Director Edward Moses. “While there have been many demonstrations of similar equivalent energy performance on individual beams or quads during the completion of the NIF project, this is the first time the full complement of 192 beams has operated at this sound barrier.”The ultraviolet energy produced by NIF (after conversion from the original infrared laser pulse to the final ultraviolet light) was 2.03 MJ before passing through diagnostic instruments and other optics on the way to the target chamber. As a result, NIF, located at Lawrence Livermore National Laboratory, is now the world’s first 2 MJ ultraviolet laser, generating nearly 100 times more energy than any other laser in operation.Satisfying the NIF objective coincides with the third anniversary of the startup of NIF operations in March 2009, when 1 MJ operation was first achieved. Since then, NIF has increased its operational energy about 1 kilojoule each day for three years, a remarkable achievement. Today, NIF is fully operational around the clock, completing important steps toward the goal of ignition and providing experimental access to national and international user communities. The 1.875 MJ shot exceeds NIF’s original design specification and sets the stage for full-power experiments over the coming months. Not only did the shot achieve the highest recorded energy threshold, it also was one of the most precise ever fired at NIF: The energy produced was within 1.3 percent of its goal. Such precision is vital because the energy distribution among the beams determines how symmetrical an implosion is obtained in capsules containing fusion fuel. Implosion symmetry is a critical factor in achieving the pressures and temperatures required for ignition. Moses said that NIF will pursue operations at even higher power and higher energy levels to achieve ignition. “Our facility’s ability to demonstrate this level of precision performance as part of routine operations is a testament to the efforts of multiple teams supporting laser operations, target chamber operations, transport and handling and optics refurbishment,” Moses said.”For the past 15 years, since NIF groundbreaking in 1997, the scientific community has regarded the 1.8 MJ milestone as a tremendous technical challenge,” said NIF Operations Manager Bruno Van Wonterghem. “In 2003, we demonstrated this performance level on a single beam line, and in 2008 we repeated the demonstration on a single quad of four beams. To achieve this performance level with this kind of precision, quality and reliability on all 192 beams is unprecedented and very exciting.”Van Wonterghem points in particular to the enormous progress NIF scientists and engineers have made in economically maintaining the facility’s optics system while operating at unprecedented energy levels. Technicians adjust the target positioner inside the NIF Target Chamber. Citation: NIF facility fires record laser shot into target chamber (2012, March 21) retrieved 18 August 2019 from ( — The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California has set a new record for a laser shot. This past week, its combined 192 lasers fired a single 1.875-megajoule shot into an empty test chamber. After passing through the last of its focusing lens, the shot reached 2.03 megajoules, making it the first 2 megajoule ultraviolet laser. Explore further Laser Bay 2, one of NIF’s two laser bays Because the facility is funded by the US nuclear weapons complex, there has been debate about whether it would ever be used to prove or disprove the idea that lasers could be used to create nuclear fusion to produce electric power. Having the laser break records doesn’t really resolve that argument in the short term, but it might in the long run if it does eventually show that electricity could be created economically using such a process. © 2011 Researchers at NIF moving closer to fusion ignition point Prior to this achievement, the most the facility had managed to coax out of the laser, the world’s largest, was 1.6 megajoules. Also, the new record shows that the NIF laser is capable of producing more than it was designed for, which was 1.8 megajoules. It also proved that it was capable of doing so without damaging its parts, allowing for another shot a day and a half later, which is important, because one of the goals for the laser is to get it to fire off shots at 15 per second eventually. That’s what researchers think will be needed to produce power economically from the laser system.The ultimate goal of the NIF is to figure out a way to use a laser to produce nuclear fusion in a way that gets more energy out than is put in. Currently, that goal is still a ways off. Thus far, engineers at the project haven’t even reached the break-even or ignition point, though they expect that to occur sometime this year. Tweaking the laser to produce more than it was designed for is a step in that direction. The NIF facility was designed to produce a fusion reaction by imploding hydrogen isotope pellets using the huge laser. To that end, the team has made steady progress. When the project first began eighteen months ago, it had just one percent of conditions in place that are believed necessary to achieve the ignition point. They have improved that mark to ten percent and it’s because the pace has picked up dramatically in recent months that they believe they will achieve the ignition point sometime over the next six months, which is when the original ignition campaign was slated to end.

Best of Last Week—The Zeno effect selfdriving cars and the genetic impact

first_img And another team with the National Institute of Standards and Technology found a way to experimentally demonstrate a 140-year-old prediction: A gas in perpetual non-equilibrium. They created a 3-dimensional cloud that never reached thermal equilibrium. In a more practical effort, a team at Cambridge University announced that they had developed a new method for scaling up quantum devices—allowing for control of 14 quantum dots with just 19 wires. Also somewhat related, a team of researchers at Harvard announced an experiment showing that light can go infinitely fast with a new on-chip material—the first on-chip metamaterial with a refractive index of zero.In other news, a group of geochemists at UCLA found evidence that suggests life on Earth likely started 4.1 billion years ago—much earlier than scientists thought—by studying zircons in a lab. And a trio of researchers (Jean-François Bonnefon, Azim Shariff and Iyad Rahwan) uploaded a paper to the preprint server arXiv, each looking at the ethical issues of self-driving cars. Each poses questions meant to stir policymakers into thinking about self-driving cars under ethical scenarios. Also, a team of researchers at the University of Queensland found 1500 ‘ageing’ genes that could lead to new treatments—which they suggest might lead to new ways to treat old age-related ailments. And an international team of researchers made an unexpected discovery—a comet that contains alcohol and sugar—comet Lovejoy , which left evidence of its makeup as it swept past our field of view this past February.And finally, if you are male and have been stressing about the impact that stress may be having on your body, you may have even more to worry about as a team at the University of Pennsylvania found that stressed dads affect offspring brain development through sperm microRNA.

Chiral superconductivity experimentally demonstrated for the first time

(Left) Illustration and (right) electron diffraction pattern of a single tungsten disulfide nanotube. Credit: Qin et al. Nature Communications Journal information: Nature Communications (—Scientists have found that a superconducting current flows in only one direction through a chiral nanotube, marking the first observation of the effects of chirality on superconductivity. Until now, superconductivity has only been demonstrated in achiral materials, in which the current flows in both directions equally.center_img Explore further The team of researchers, F. Qin et al., from Japan, the US, and Israel, have published a paper on the first observation of chiral superconductivity in a recent issue of Nature Communications. Chiral superconductivity combines two typically unrelated concepts in a single material: Chiral materials have mirror images that are not identical, similar to how left and right hands are not identical because they cannot be superimposed one on top of the other. And superconducting materials can conduct an electric current with zero resistance at very low temperatures.Observing chiral superconductivity has been experimentally challenging due to the material requirements. Although carbon nanotubes are superconducting, chiral, and commonly available, so far researchers have only successfully demonstrated superconducting electron transport in nanotube assemblies and not in individual nanotubes, which are required for this purpose. “The most important significance of our work is that superconductivity is realized in an individual nanotube for the first time,” coauthor Toshiya Ideue at The University of Tokyo told “It enables us to search for exotic superconducting properties originating from the characteristic (tubular or chiral) structure.”The achievement is only possible with a new two-dimensional superconducting material called tungsten disulfide, a type of transition metal dichalcogenide, which is a new class of materials that have potential applications in electronics, photonics, and other areas. The tungsten disulfide nanotubes are superconducting at low temperatures using a method called ionic liquid gating and also have a chiral structure. In addition, it’s possible to run a superconducting current through an individual tungsten disulfide nanotube.When the researchers ran a current through one of these nanotubes and cooled the device down to 5.8 K, the current became superconducting—in this case, meaning its normal resistance dropped by half. When the researchers applied a magnetic field parallel to the nanotube, they observed small antisymmetric signals that travel in one direction only. These signals are negligibly small in nonchiral superconducting materials, and the researchers explain that the chiral structure is responsible for strongly enhancing these signals.”The asymmetric electric transport is realized only when a magnetic field is applied parallel to the tube axis,” Ideue said. “If there is no magnetic field, current should flow symmetrically. We note that electric current should be asymmetric (if the magnetic field is applied parallel to the tube axis) even in the normal state (non-superconducting region), but we could not see any discernible signals in the normal state yet, interestingly, it shows a large enhancement in the superconducting region.”Currently, the researchers aren’t exactly sure what causes the asymmetric electric transport in the chiral superconducting nanotubes. They plan to further investigate these mechanisms in the future, which would reveal new insight into the relationship between superconductivity and chirality. “Our next plan is to understand the microscopic mechanism of the observed phenomena,” Ideue said. “In addition, we will try to verify the universality of the nonreciprocal superconducting transport and its enhancement in the superconducting region.”Although it may be too early to tell what kinds of applications chiral superconductivity might have, the researchers explain that the one-way effect shares similarities with existing technologies.”One thing we can say is that nonreciprocal electric transport can be understood as a ‘rectification effect’ or ‘diode-like functionality’ (if it is large) so that it might be used to realize a ‘superconducting diode’ which could have potential applications for superconducting circuits,” Ideue said. More information: “Superconductivity in a chiral nanotube.” Nature Communications. DOI: 10.1038/ncomms14465AbstractChirality of materials are known to affect optical, magnetic and electric properties, causing a variety of nontrivial phenomena such as circular dichiroism for chiral molecules, magnetic Skyrmions in chiral magnets and nonreciprocal carrier transport in chiral conductors. On the other hand, effect of chirality on superconducting transport has not been known. Here we report the nonreciprocity of superconductivity—unambiguous evidence of superconductivity reflecting chiral structure in which the forward and backward supercurrent flows are not equivalent because of inversion symmetry breaking. Such superconductivity is realized via ionic gating in individual chiral nanotubes of tungsten disulfide. The nonreciprocal signal is significantly enhanced in the superconducting state, being associated with unprecedented quantum Little-Parks oscillations originating from the interference of supercurrent along the circumference of the nanotube. The present results indicate that the nonreciprocity is a viable approach toward the superconductors with chiral or noncentrosymmetric structures. This document is subject to copyright.

More information: Nora Hassan et al. Evidence for a quantum dipole liquid state in an organic quasi–two-dimensional material, Science (2018). DOI: 10.1126/science.aan6286AbstractMott insulators are commonly pictured with electrons localized on lattice sites, with their low-energy degrees of freedom involving spins only. Here, we observe emergent charge degrees of freedom in a molecule-based Mott insulator κ-(BEDT-TTF)2Hg(SCN)2Br, resulting in a quantum dipole liquid state. Electrons localized on molecular dimer lattice sites form electric dipoles that do not order at low temperatures and fluctuate with frequency detected experimentally in our Raman spectroscopy experiments. The heat capacity and Raman scattering response are consistent with a scenario in which the composite spin and electric dipole degrees of freedom remain fluctuating down to the lowest measured temperatures. Explore further A team of researchers with members from several institutions in the U.S. and Russia has found evidence that suggests spin liquids in ferromagnets may be similar to dipole liquids in ferroelectrics. In their paper published in the journal Science, the group describes their study of molecular crystals and what they found. Ben Powell with the University of Queensland offers a Perspective piece on the work done by the team in the same journal issue. As Powell explains, the researchers were looking at the behavior of dipole liquids, which are theorized particles that are still not very well understood. Some phases of matter are relatively easy to observe—the spins of ferromagnets, for example. Other are not, such as the spin liquids. In this new effort, the researchers took advantage of features unique to molecular crystals—the structure and dipole inherent in dimer Mott insulators. To that end, they studied specific types of salts, noting that in the dimer Mott phase, most such dimers have a +1 charge. To conduct their study, they used Ramen scattering, comparing what they observed against vibrational models. Doing so allowed them to analyze dipolar fluctuations.The researchers report that they believe their experiments revealed evidence of excitations of dipoles or perhaps hybrid spin-dipole excitations that were provoked by interactions between the unpaired spins and dipoles. This, Powell explains, leads to the question of whether spin-dipole interactions might be involved in the particles observed in the salts—that is, if the excitations actually have hybrid spin dipole characteristics. If so, there lies the possibility that dipole liquids are similar in nature to spin liquids. If that is the case, Powell says, then the work by the team might have led to more questions than answers. But in either case, it offers other physicists new avenues of research efforts. Powell concludes by suggesting further work might involve the development of new tools that can be used to probe particle-like excitations directly—a means of proving one way or another if the two liquid states are truly alike, and if so, how closely. © 2018 Crystal structure and phases of BEDT-TTF–based crystals.

Weaknesses in EmotionExpression Research Outlined in New Report

first_img For more information about this study, please contact: Lisa Feldman Barrett at or 617-794-4409, Ralph Adolphs at, Stacy Marsella at, Aleix Martinez at, or Seth Pollak at or 608-698-2523. Read coverage of this report in The Washington Post, Forbes, The Verge, and the ACLU’s Free Future blog “It is not possible to confidently infer happiness from a smile, anger from a scowl or sadness from a frown, as much of current technology tries to do when applying what are mistakenly believed to be the scientific facts,” a group of leading experts in psychological science, neuroscience and computer science write in their comprehensive research review. “People scowl when angry, on average, approximately 25% of the time, but they move their faces in other meaningful ways when angry,” Barrett explains. “They might cry, or smile, or widen their eyes and gasp. And they also scowl when not angry, such as when they are concentrating or when they have a stomach ache. Similarly, most smiles don’t imply that a person is happy, and most of the time people who are happy do something other than smile.” The authors note that the general public and some scientists believe that there are unique facial expressions that reliably indicate six emotion categories: anger, sadness, happiness, disgust, fear, and surprise. But in reviewing more than 1,000 published findings about facial movements and emotions, they found that typical study designs don’t capture the real-life differences in the way people convey and interpret emotions on faces. A scowl or a smile can express more than one emotion depending on the situation, the individual, or the culture, they say. In a separate article in the journal, Alan Cowen and Dacher Keltner of the University of California, Berkeley; Disa Sauter of the University of Amsterdam; and Jessica L. Tracy of the University of British Columbia note that most scientists agree that facial expressions are meaningful, even if they don’t follow a one-to-one match with six basic emotion categories. They propose a new model for studying emotion-related responses in all their complexity and variations. This approach would measure not only facial cues, but also body movements, voice fluctuations, head movements and other indicators to capture such nuanced responses as smiles of embarrassment or sympathetic vocalizations, they say.center_img “We thought this was an especially important issue to address because of the way so-called ‘facial expressions’ are being used in industry, educational and medical settings, and in national security,” say Barrett and her co-authors. The full text of the report and commentary are available to the public online. Software that purports to read emotions in faces is being deployed or tested for a variety of purposes, including surveillance, hiring, clinical diagnosis, and market research. But a new scientific report finds that facial movements are an inexact gauge of a person’s feelings, behaviors, and intentions. The report appears in Psychological Science in the Public Interest, and is authored by APS President Lisa Feldman Barrett of Northeastern University, Ralph Adolphs of the California Institute of Technology, Stacy Marsella of Northeastern University and the University of Glasgow, Aleix M.

Efforts on to make Buxa Tiger Reserve a plasticfree zone

first_imgKolkata: The state Forest department is striving to make Buxa Tiger Reserve (BTR) in Alipurduar district of North Bengal a plastic-free zone. The tourists visiting the BTR are being offered paper bags free of cost and in case they are carrying plastic, the things in it are being put inside those paper bags.”We are taking all possible measures to make BTR plastic free. It is a massive challenge for us as the area in and around the reserve is a populated one. A number of slums are also located inside the forest area itself. We have started offering paper bags to tourists at the ticket counter of BTR,” state Forest minister Binay Krishna Barman said. The state Forest department will be soon introducing a dozen of Royal Bengal Tigers in BTR in a bid to augment tiger population there. The tigers will be brought from the forest reserves in Assam, which have a similar flora and fauna as the Buxa forest. Also Read – Rain batters Kolkata, cripples normal lifeThe state has already written to the Assam government for procuring a dozen tigers. It has been learnt that Buxa is one of the three forests in India where the National Tiger Conservation Authority has approved the tiger augmentation programme. It is located close to Assam’s Manas Tiger Reserve and some experts believe that animals from Manas often come to Buxa using Bhutan as a corridor. The BTR is home to smaller cats such as leopards which occasionally surface in the tea gardens nearby. There are also common clouded leopards, jungle cats and fishing cats. The herbivore list includes elephants, Indian gaur, chital, sambars, barking deer and hog deer. The tiger reserve has an area of about 757.9 sq km, of which 390 sq km lies in the core area and 367 sq km in the buffer zone. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe Forest department has decided to bring sambar and bison to the Buxa Tiger Reserve from other wildlife sanctuaries to boost the food chain ahead of the introduction of big cats in the BTR. “A number of heribivore needs to be present in Buxa for the food of the tigers. So, 250 spotted deer have already been moved to Buxa. We have decided to bring in at least 50 sambars and a good number of bisons from Jaldapara National Park to the BTR,” a senior Forest department official said. The number of tigers in Buxa has been often debated by wildlife enthusiasts. While Forest Department officials claimed there were tigers in the reserve, almost no sighting of the big cats raised questions about their presence. The survey of tigers in 2011 based on DNA analyses put the number of tigers at 20.last_img read more

Tale of the fallen empire

first_imgOn September 14, 1857, British Troops launched an attack on the besieged city of Delhi, bringing a bloody end to the Sepoy Mutiny by massacring not only the rebels, but also the ordinary citizens of the Mughal capital. 159 years later to the day, on a pleasant autumn evening in the national Capital, memories of the faded grandeur of imperial Delhi hung heavy in the air as William Dalrymple sat down for a discussion on his most famous work, ‘The Last Mughal’. Also Read – Add new books to your shelfThe event which celebrated the Hindustani edition of Dalrymple’s magnum opus was also attended by its translator Zakia Zaheer and singer Vidya Shah. The session at the Oxford Bookstore was marked by readings and music, and brought alive historical references for the audience, as the panel took them through the vivid descriptions of life from the Mughal era.Dalrymple described how Bahadur Shah Zafar, the last of the Mughals, was someone who was “quite magnificently unsuited to lead a revolution” of the scale of the 1857 mutiny. “The face off was between two different worlds,” Dalrymple said. A doomed romantic figure like Zafar on one side of the ring against the East India Company – a force that was four times the size of the British Army in the year of the mutiny.The East India Company was, as Dalrymple put it, like an evil multinational corporation, with the difference that it had an army. Also Read – Over 2 hours screen time daily will make your kids impulsive“For the last 100 years, we have been taught to think about colonialism as the British coming here. But it is much worse than that – it is a multinational corporation, like Union Carbide with armies, Google with weapons, Rio Tinto with infantry regiments,” he said. The scale of killings on that fateful day was on a level that was infinitely greater than the massacre at Jalianwala Bagh, Dalrymple said. English troops proceeded to systematically murder every able citizen at gunpoint, leaving the city of half a million people an empty ruin.  Zakia Zaheer who spent a year translating the book in Hindi, meanwhile read out captivating excerpts from the translated version of the book, describing the majestic sheen of the Mughal court at a time when it still held some semblance of power. The readings were interspersed with soulful vocals by singer Vidya Shah, who has also worked with Dalrymple earlier in a concert based on the book.Zaheer also stated that Dalrymple had offered an impartial account of all the facts in his book. When asked to elaborate on his idea of history being written from the point of view of the vanquished and not the victor in his book, the author said, “The whole exercise is in essence to try and bring back the Indian version. Normally the excuse is this, that there are no documents. So one has to always use the British texts. Right from the beginning, I knew that there were papers in the national archives. 20,000 documents taken from the rebel camps which were used for evidence in the trails that followed. I came across this stash of papers while researching for my previous book. So that was the heart of the whole project, putting the defeated side story forward.”Dalrymple also spoke about the writer’s block, “I think if you’re well planned and have got everything organized, there’s no excuse for having the writer’s block while writing non-fiction. The story is already in front of you. You know what’s happening. I spent 4-5 years preparing my ingredients, if you like it, and only then did I write. If you’re well organised you shouldn’t have the writer’s block. That’s something novelists experience when they are writing fiction”, He is currently writing a book on the Kohinoor diamond.last_img read more

Thinking of close ones can help reconnect with real people

first_imgReminding people of their close, caring relationships can reduce their tendency to anthropomorphise objects – ascribing humanlike characteristics to inanimate objects – as a way of feeling socially connected, and help people reconnect with real people, suggests new research.“Although anthropomorphism is one of the more creative ways people try to meet belonging needs, it is nevertheless difficult to have a relationship with an inanimate object,” the researchers said. There are many ways that people who feel socially disconnected can reconnect – they can try reinforce existing social bonds or forge new relationships, but there are other ways, too.  Also Read – Add new books to your shelfAn earlier study showed that one of the ways that people may try to increase their sense of connection and belonging is by anthropomorphising inanimate objects, such as a pillow or an alarm clock.“Reliance on such a compensatory strategy could permit disconnected people to delay the riskier – but potentially more rewarding – steps of forging new relationships with real people,” the current study noted.“We think this work really highlights how important feeling socially connected is to people and the lengths people will go to ‘reconnect’ when they feel disconnected, and it reminds us of the value of our close relationships,” lead researcher Jennifer Bartz of McGill University in Montreal, Quebec, Canada. The researchers wondered whether boosting people’s feelings of social connection might make them less likely to anthropomorphise. Also Read – Over 2 hours screen time daily will make your kids impulsiveThey also explored whether attachment anxiety – marked by a preoccupation with closeness and intimacy and heightened sensitivity to social cues of rejection – might be one individual characteristic associated with this tendency to anthropomorphise.To find out, the researchers conducted an online experiment with a total of 178 participants, who completed a variety of established survey measures aimed at assessing their feelings of attachment anxiety and avoidance, loneliness, self-esteem, and need to belong.Some of the participants were then asked to think about someone who was important to them and whom they could trust.Other participants completed the same tasks but were told to think about an acquaintance, instead of someone they were close to, serving as a comparison group. The results, published in the journal Psychological Science, showed that thinking about a close relationship can make a difference.Participants who thought and wrote about someone they were close to were less likely to anthropomorphise objects compared with participants who thought about an acquaintance.In addition, the researchers found that attachment anxiety was associated with a tendency to anthropomorphise, and was actually a stronger predictor than loneliness was.last_img read more
