Advent of Cold Plasma

first_img This new device which is a major improvement on the earlier plasma jet devices has been developed by Mounir Laroussi and XinPei Lu at the Old Dominion University in Virginia, could be used to kill bacteria, heal wounds and treat plaque.At atmospheric pressure, most plasmas are so hot (thousands of degrees centigrade) that they would immediately kill any living cells they come into contact with. Moreover, these high-temperature plasmas are also very difficult to control. In recent years, however, researchers have developed techniques for producing low-temperature plasmas and some of these have been used in biomedical applications. However, till now the replacement were not very reliable.A good low-temperature plasma source must be able to work at room temperature and atmospheric pressure. Moreover, it should be hand-held and must not “arc” and heat up while operating. The new device developed by Laroussi and Lu consists of two electrodes, each made of a thin copper ring attached to the surface of a glass disk: the disk is about 2.5 centimetres across and has a small hole at its centre. These electrodes are then inserted into a dielectric tube and are separated by a gap that can be varied between 0.5 and 1 centimeter.When helium gas is injected into the tube and short (less than one microsecond) high-voltage pulses are applied to the electrodes, a discharge is ignited in the gap between the electrodes. This produces a plasma plume that is ejected through the hole in the outer electrode. The plume can be up to 5 centimetres long, with the length depending on the flow rate of the helium and the size of the voltage pulses. The plume remains at room temperature and can be touched by bare hands.The device is an improvement on previous plasma “jet” devices that only generate short plumes that have lengths in the millimetre range and can reach temperatures several tens of degrees above room temperature. And unlike other devices, such as the “plasma needle”, the new apparatus contains no sharp metal objects. And since very short voltage pulses are used, there is no risk of arcing and heating if the device is deployed for long periods.This development of cold plasma can have far reaching effects not only in biomedical sciences, but also in all areas where plasma are used. Its portability has added benefit. This might help the scientists and researchers use plasma in other fields.Dr. Bikram Lamba, an international management consultant, is Chairman & Managing Director of Tormacon Limited- a multi-disciplinary consultancy organization.He can be contacted at 9058484205.

Researchers find evidence of quantum critical point in high temperature superconductivity material

first_img Journal information: Science A material’s QCP is analogous to the phase changes in ordinary materials, such as ice melting to water. In the quantum world, rather than occurring due to the ordering of atoms, they are based on electronic carriers, and come about as a result of interactions rather than organization. At the QCP, the properties of the material change suddenly, due to quantum fluctuations. Researchers have suspected that the reason materials with Tc are able to become super conductive (have no resistance to an electrical charge) is because they have a QCP, but thus far have not been able to prove it.In this new research, the team has come close. They worked with a Tc known as an iron pnictide, because of its location on the periodic table; in this case it was arsenic. To test the material for a QCP, the team first added a doping factor to provide an extra charge. When put in an extremely cold environment and adding just the right amount of the doping factor, the material becomes a superconductor.To test the material to see if it had a QCP, the team turned to a measurement method known as the London penetration depth, which measures the depth to which a magnetic field penetrates a given material. In so doing, the team was able to see a very noticeable jump in the penetration depth with their sample as the doping factor was tweaked to its optimal value.Unfortunately, while the jump is a good sign that the Tc sample does likely have a QCP, it’s not definitive proof, though it does come close. Close enough that it gives researchers a renewed belief that their theoretical models have been correct all along, likely leading to new research that might just uncover some other mysteries still surrounding super conducting materials. Physicists show standard ‘quasiparticle’ theory breaks down at ‘quantum critical point’ ( — In the seemingly never ending search for a superconductor that can operate at or near room temperature, researchers have discovered a lot of things about superconductors in general. One of these is that there appears to be two classes of them – those materials that only take on their superconductive properties when exposed to an environment just a few degrees above absolute zero, and those that do the same at somewhat higher temperatures. Those in the latter group are said to have high critical-temperature superconductivity (Tc). Unfortunately, researchers have made little progress in understanding how such materials are able to do what they do. Now, new research by a team of Japanese, British and American researchers has found that at least one of these Tc materials likely has a quantum critical point (QCP), which if true, would go a long way towards explaining why some materials are able to become superconductors at higher temperatures than others. They have published a paper detailing their findings in the journal Science. More information: A Sharp Peak of the Zero-Temperature Penetration Depth at Optimal Composition in BaFe2(As1–xPx)2, Science 22 June 2012: Vol. 336 no. 6088 pp. 1554-1557 DOI: 10.1126/science.1219821ABSTRACTIn a superconductor, the ratio of the carrier density, n, to its effective mass, m*, is a fundamental property directly reflecting the length scale of the superfluid flow, the London penetration depth, λL. In two-dimensional systems, this ratio n/m* (~1/λL2) determines the effective Fermi temperature, TF. We report a sharp peak in the x-dependence of λL at zero temperature in clean samples of BaFe2(As1–xPx)2 at the optimum composition x = 0.30, where the superconducting transition temperature Tc reaches a maximum of 30 kelvin. This structure may arise from quantum fluctuations associated with a quantum critical point. The ratio of Tc/TF at x = 0.30 is enhanced, implying a possible crossover toward the Bose-Einstein condensate limit driven by quantum criticality.

With a global launch date of 2014, NEC is testing its DNA analysis device with the National Research Institute of Police Science, affiliated with the National Police Agency, in Japan. The price for the analyzer is US$120,000. The 2014 model will weigh around 32 kg, measuring 850(W) by 470(D) by 250 (H) mm, which has earned it the reference of being suitcase-sized, though a heavy suitcase at that. An NEC spokesperson said the company’s initial user target will be investigative organizations such as police. The DNA analyzer will also be targeted to help during natural disaster crises, “for use on victims of natural disasters, to quickly match samples from siblings and parents.”NEC’s technology that is making this type of portable analyzer possible is essentially a “lab on a chip.” This chip is disposable, which avoids DNA mistyping. The NEC team behind this device has put the full DNA extraction, PCR (polymerase chain reaction) amplification and Electrophoresis stages on a chip. In so doing they have been able to recreate the lab processes. NEC said that the device will not require anything beyond minimal training; the capsule has a suite of reagents that eliminates the need to use pipettes. NEC said that “laymen” can inject extracted DNA in the well on the chip. After analysis, the chip can be safely disposed of. The waste area in the chip will free operators from the task of tedious cleaning, added NEC.Development of the analyzer by NEC is being carried out with partners including Promega, a U.S. biotechnology firm.

The NEC analyzer integrates all steps required in DNA analysis. By 2014, NEC intends to issue a model that will be able to process samples at the scene of a crime or at disaster sites in as little as 25 minutes. The current version of the analyzer takes about an hour for all DNA-determining tasks, but NEC intends to bring the time down to 25 minutes. The new analyzer’s ability to output samples quickly for use with DNA databases can have a significant effect on crime-solving and helping people who are victims of natural disasters. © 2012 Phys.orglast_img read more

OpenGlass apps show support for visually impaired w Video

first_img © 2013 The video first shows a demo with a Question-Answer app. This app turns to Amazon’s Mechanical Turk and Twitter for help in identifying objects. Users take a picture with a question attached, which is sent for answers on Twitter or Amazon’s Mechanical Turk. In this scenario the visually impaired user asks Google Glass what an object is (“What is this a can of?”) and gets a reply. The other app, called Memento, carries images and annotations that a sighted user first creates so that the information can then be heard by the visually impaired user. The sighted person creates and describes the scene. Once that is done, the visually impaired person, wearing Glass, can know what items are in the room. Glass recognizes the scene and reads back the sighted person’s earlier commentary. Memento can warn users about dangerous equipment, for example.

Theorists propose globally networked entangled atomic clock

first_img Researchers build two versions of new most accurate clock ever This document is subject to copyright. 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. Explore further ( —A small team of physicists from the U.S. and Denmark has published a paper in the journal Nature Physics outlining the idea of a collection of atomic clocks located around the world—all networked via entangled particles. They propose that such a system of clocks would be far more accurate than anything that exists today. Citation: Theorists propose globally networked entangled atomic clock (2014, June 16) retrieved 18 August 2019 from © 2014 Phys.orgcenter_img Journal information: Nature Physics The concept of world-wide quantum clock network. Credit: Nature Physics (2014) doi:10.1038/nphys3000 The idea of networking clocks involves two areas of research—atomic clocks and entanglement. Atomic clocks are of course the most accurate time devices available today—they track time by measuring the resonance frequency of atoms—generally caesium. And entanglement is where pairs of particles are linked in ways that are still not fully understood—what happens to one automatically happens to the other, regardless of distance. To make a global networked clock, the researchers propose, would involve setting up a bunch of atomic clocks at various sites around the globe (and one or more in space) and then entangling particles between each of them, one after the other. The result would be a single clock that would be more precise than any of its component clocks. That would be possible, the team notes, because entanglement would allow for reduced measurement noise in all of the clocks.If such a network could be built, it would mean an unprecedented level of accuracy, which would in turn mean improvements in devices that rely on time accuracy, such as GPS. It could also serve as a platform for physicists studying gravitational waves.The researchers note that a shared global clock would be more stable than clocks used today because they would be constantly updating—the more clocks in the network, the more stable the clock as a whole would be. It would also be secure, they add, because anyone trying to tap into it would be instantly discovered, courtesy of the laws of quantum mechanics. They believe such a global clock would be up to 100 times more accurate than anything we have today, which is saying a lot—a modern atomic clock is so accurate that it would take 300 million years to gain or lose just one second.Building such a networked clock, even if a plan and funding were available, is still a long way off, of course, scientists still have a lot to learn about entanglement, both how it works, and how to use it. More information: A quantum network of clocks, Nature Physics (2014) DOI: 10.1038/nphys3000AbstractThe development of precise atomic clocks plays an increasingly important role in modern society. Shared timing information constitutes a key resource for navigation with a direct correspondence between timing accuracy and precision in applications such as the Global Positioning System. By combining precision metrology and quantum networks, we propose a quantum, cooperative protocol for operating a network of geographically remote optical atomic clocks. Using nonlocal entangled states, we demonstrate an optimal utilization of global resources, and show that such a network can be operated near the fundamental precision limit set by quantum theory. Furthermore, the internal structure of the network, combined with quantum communication techniques, guarantees security both from internal and external threats. Realization of such a global quantum network of clocks may allow construction of a real-time single international time scale (world clock) with unprecedented stability and accuracy.last_img read more

Naked mole rat found to defy Gompertzs mortality law

first_img Naked mole rats are very nearly hairless. They evolved that way by living in a harsh underground environment. They are also almost ectothermic (cold blooded). And now, it seems they do not age—at least in the traditional sense. Reports of long-lived mole rats prompted the team at Calico to take a closer look—they have a specimen in their lab that has lived to be 35 years old. Most “normal” rats, in comparison, live to be just six years old, and they age as they do so.Naked mole rats also have some other interesting biological features—they very rarely develop cancer, they experience very little pain and they have been found able to survive without oxygen for up to 18 minutes by going into a plant-like vegetative state. Also, they never reach menopause, and can have offspring right up until their death—and their hearts and bones never show signs of aging. But it was their longevity that was the focus of this new effort.The team collected what they describe as 3,000 points of data regarding the lifespan of the naked mole rat, and found that many had lived for 30 years. But perhaps more surprisingly, they found that the chance of dying for the mole rats did not increase as they aged. All other mammals that have been studied have been found to conform to what is known as Gompertz’s mortality law, which states that the risk of death for a typical mammal grows exponentially after they reach sexual maturity—for humans, that means the odds of dying double every eight years after reaching age 30. This, the researchers claim, suggests that mole rats do not age—at least in the conventional sense. They do eventually die, after all.The research team concludes by suggesting that a lot more work needs to be done with naked mole rats to find out if they are aging, but are doing so very slowly. Most captive mole rats, they note, are killed for research purposes, so there is little good data on how long they actually live. A team of researchers at Google-owned Calico Life Sciences LLC has found that the naked mole rat defies Gompertz’s mortality law. In their paper published in eLife, the group describes their study of the unusual-looking rodent and describe some of its unusual traits. More information: J Graham Ruby et al. Naked mole-rat mortality rates defy Gompertzian laws by not increasing with age, eLife (2018). DOI: 10.7554/eLife.31157AbstractThe longest-lived rodent, the naked mole-rat (Heterocephalus glaber), has a reported maximum lifespan of >30 years and exhibits delayed and/or attenuated age-associated physiological declines. We questioned whether these mouse-sized, eusocial rodents conform to Gompertzian mortality laws by experiencing an exponentially increasing risk of death as they get older. We compiled and analyzed a large compendium of historical naked mole-rat lifespan data with >3000 data points. Kaplan-Meier analyses revealed a substantial portion of the population to have survived at 30 years of age. Moreover, unlike all other mammals studied to date, and regardless of sex or breeding-status, the age-specific hazard of mortality did not increase with age, even at ages 25-fold past their time to reproductive maturity. This absence of hazard increase with age, in defiance of Gompertz’s law, uniquely identifies the naked mole-rat as a non-aging mammal, confirming its status as an exceptional model for biogerontology.

Could aliens harness stars to keep ahead of expanding universe

first_img A Dyson sphere is a theoretical structure able to house a star. Originally proposed by Freeman Dyson, the sphere was originally envisioned as a group of satellites completely encompassing a star to capture all of its energy. That energy could then be used for whatever purposes the civilization that created it desired. In this new effort, Hooper suggests aliens might be creating similar structures to provide power once the universe expands to an untenable size.Prior research has shown that the universe is not just expanding, it is picking up speed as it does so due to dark energy. This means that almost everything in the universe is being flung farther apart from everything else. Such a scenario suggests that galaxies will become increasingly isolated, though the components of the galaxies will remain bound by gravity. So, Hooper wonders, what would an alien race do to ensure it has a steady source of power? He suggests they might be collecting stars at this very moment, getting ready for the days ahead when they will be too far away to grab.Hooper notes that such a scenario is still very far off—on the order of 100 billion years from now. But he also notes that if aliens were grabbing stars from one galaxy and transporting them back to another, the time for each trip would be on the order of billions of years. Thus, they would have to be doing it now, before they run out of time. He acknowledges that humans would probably not be able to understand the mechanics of moving a star, but muses on the possibility of an alien race powerful enough to do so. He further suggests that if such activity is currently happening, we might be able to see evidence of it by looking for stars that seem to be moving between galaxies—or by looking for holes in galaxies where stars have already been removed.

In his paper uploaded to the arXiv preprint server, he suggests they might consider collecting and storing stars. More information: Life Versus Dark Energy: How An Advanced Civilization Could Resist the Accelerating Expansion of the Universe, arXiv:1806.05203 [astro-ph.CO] presence of dark energy in our universe is causing space to expand at an accelerating rate. As a result, over the next approximately 100 billion years, all stars residing beyond the Local Group will fall beyond the cosmic horizon and become not only unobservable, but entirely inaccessible, thus limiting how much energy could one day be extracted from them. Here, we consider the likely response of a highly advanced civilization to this situation. In particular, we argue that in order to maximize its access to useable energy, a sufficiently advanced civilization would chose to expand rapidly outward, build Dyson Spheres or similar structures around encountered stars, and use the energy that is harnessed to accelerate those stars away from the approaching horizon and toward the center of the civilization. We find that such efforts will be most effective for stars with masses in the range of M∼(0.2−1)M⊙, and could lead to the harvesting of stars within a region extending out to several tens of Mpc in radius, potentially increasing the total amount of energy that is available to a future civilization by a factor of several thousand. We also discuss the observable signatures of a civilization elsewhere in the universe that is currently in this state of stellar harvesting.

Closer look at supernova dust suggests theres more of it than previously

first_img Journal information: Nature Astronomy Citation: Closer look at supernova dust suggests there’s more of it than previously assumed (2019, June 18) retrieved 18 August 2019 from Scientists have known for some time that dust emitted by stars makes its way to our solar system. They have also known that some of that dust comes from supernovas. In this new effort, the researchers claim that they have found evidence that more of the interstellar dust that makes it to Earth comes from supernovas than previously thought.The researchers suggest that the reason less star dust was attributed to supernovas was because researchers lacked the tools to properly examine the grains of dust. They further report that the development of a Cameca NanoSIMS 50 ion probe allowed them to measure such dust in better detail. Their measurement process also included the use of an ion mass spectrometer capable of measuring isotopes with high spatial resolution. By using the new technology, the researchers determined how much of the dust came from regular stars churning away, and how much came from supernovas (less than 1 percent). The percentage that originated from supernovas was higher than expected—this suggests that more of the star dust that makes it to Earth has a supernova origin. And that suggests that more of the star dust in space originated in supernovae than has been thought.The dust studied by the researchers was obtained from chondrite samples found in Northwest Africa. Close study via the new technology allowed the researchers to measure the amount of magnesium they contained, which they also note predates our own star. They point out that most of the material in our solar system was created from material ejected from stars; thus, a better understanding of stardust could lead to a better understanding of how we got here.

The dusk of life

first_imgEmbracing a poignant theme, Sandhya Chhaya, a play directed by Basab Bhattacharya portrays the life of an aged couple set amidst comtemporary times. It will be staged in thrice in Alliance Francaise starting from 27 July.Sandhya Chhaya, as the name signifies, is about the shadow which is cast upon the  evening or the final lap  of the life of an elderly lonely couple who endlessly waits for its offsprings to come and wipe away the loneliness hounding the husband-wife. Also Read – ‘Playing Jojo was emotionally exhausting’Through this play a conscious effort has been made to convey a message to the youth as well as the senior generation that, firstly do not neglect senior citizens. They are a mirror image of your old age. Secondly do not depend on your children for your share of happiness. Create your own independent world where dependency on the younger generation for company does not exist. If the senior citizens do not do so then sadly their end might be similar to that of the protagonist couple in the play. The play showcases the relentless efforts of a couple to find company; be it through a wrong number or a servant or even a passerby who mistakenly knocks at their door. Such is the desperation.Few other social issues have also been taken care of through Sandhya Chhaya, such as; growing discontentment among the youth against the country’s corrupt and immoral conscience. As a result the youth is losing confidence and not willing to settle in India if given an opportunity.last_img read more

first_imgBuying clothes is easy but maintaining them is important. Don’t store clothes in a plastic bag and before storing dry clean them, say experts.4Before packing the clothes, dry clean and wash them. Dirty clothing can attract vermin and insects which may damage your clothing so wash and iron them before storing.4Avoid plastic bags as these can trap moisture and cause mildew to form or cause the yellowing of fabrics. Acid-free boxes and tissue paper should be used as not all plastic boxes are safe as they release chemicals which could have subtle to grossly negative effects on the clothing.

With all the same hangers, your wardrobe will look like an emporium, and if all the garments are level, they are a lot easier to see. Try the rubber covered non-slip hanger.4To deter dreaded moth holes in clothes use lavender bags or cedar wood in your storage boxes as these natural products work really well.4Don’t store your footwear with your garments as fumes from the leather and glue may cause damage and discolouration.4Just like the storage material, there needs to be thought put into the storage locations. This means stuffy areas like attics and basements are a strict no-no. The best space would be a dark area with good air circulation.

Night phone use may harm mental health in teens

first_imgTeenagers who use their smartphones late at night may have low sleep quality, leading to poor mental health, reduced coping and self-esteem, a new study warns.Researchers at Griffith University and Murdoch University tracked changes in late-night mobile phone use, sleep and mental health indicators over three years in a large sample of Australian teens.They found that adolescents’ late-night mobile phone use was directly linked to poor sleep quality, which subsequently led to poorer mental health outcomes, reduced coping, and lowered self-esteem. Also Read – Add new books to your shelf”We have demonstrated how poor sleep is the key link connecting an increase in night-time mobile use with subsequent increases in psychosocial issues,” lead researcher Lynette Vernon said. “We found that late night phone use directly contributed to poor sleep habits, which over time led to declines in overall wellbeing and mental health,” said Vernon.The study surveyed 1,100 students from 29 schools annually over four years in total, starting in year eight and following them until year 11. Students were asked what time of the night they received or sent text messages and phone calls, and their perceptions of their sleep quality. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe researchers also investigated adolescents’ symptoms of depressed mood, involvement in delinquency or aggression, and their coping and self esteem over time. Results showed that in year eight, more than 85 per cent of students owned a mobile phone and around one-third of these students reported they never texted or received phone calls after lights out.”We found that those teenagers who start out as relatively ‘healthy’ in terms of their late-night mobile use early in high school, tend to show steeper escalations in their late-night mobile use over the next several years,” said study co-author Kathryn Modecki. Students with high initial levels of night-time mobile phone use also tended to have higher initial levels of poor sleep behaviour.As their levels of mobile phone use grew over time, so did their poor sleep behaviour. “What is especially compelling is that these increases in poor sleep, in turn, led to rises in depressed mood and externalising behaviours, and declines in self-esteem and coping one year later.”last_img read more

first_imgKolkata: Renowned Bengali film director Shrikant Mohta was arrested by the Central Bureau of Investigation (CBI) on Thursday for allegedly defrauding ponzi chit fund company Rose Valley.It has been alleged by the investigating agency that Mohta has duped Rose Valley chief Gautam Kundu by taking Rs 24 crore for the making of several films. However, a statement from Shree Venkatesh Films said: “CBI has, in the past few months, called Shrikant Mohta for investigation in the Rose Valley Chit fund matter as a witness, owing to past business transactions between SVF and Brand Value (a Rose Valley Group company) and on account of past legal cases on the same matter, where the High Court of Kolkata had quashed all charges alleged against Mohta and the same was affirmed by the Supreme Court of India.” Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedIt further maintained: ” Mohta appeared before CBI twice in the past as a witness and fully cooperated with the investigation. However, on account of personal reasons, he was not able to appear before CBI in the month of January. This was communicated to the CBI with a request to grant him time of 15 days. Mohta even offered his cooperation to CBI in the interim period by requesting them to provide any information required by the CBI from him.” Mohta is the co-founder of Shree Venkatesh Films, which has produced over 120 films.

According to the CBI, investigation has revealed that in pursuance of criminal conspiracy with said group of companies, the accused allegedly misappropriated Rs 24 crore (approx) in the name of producing films and siphoned off this money illegally collected by the said ponzi scheme company from the residents of Bengal, Assam, Odisha and elsewhere. It was further alleged that he invested part of funds in procurement of paintings through a private film company and he also foisted other accused persons in ponzi scheme cases to make similar purchases. The private group of the chit fund company had collected Rs 15,000 crore(approx) from public. It has been alleged that as Mohta did not respond to the summons that were issued, CBI sleuths on Thursday raided Mohta’s company SVF Entertainment Private Limited’s Kasba office. Mohta was detained from his office amid much drama. When the CBI arrived at his office, he reportedly called up the local police station and complained that some hooligans were creating a disturbance outside his office. The police rushed in only to realise that it was a full-fledged CBI operation. Mohta was questioned for almost two-and-a-half-hours there. Later he was taken to the CGO Complex in Salt Lake for interrogation and eventually detained. He was arrested later in the day. Mohta will be produced before the Court of Special CJM, CBI Cases, Bhubaneswar, on Friday. Meanwhile, the Trinamool Congress (TMC) on Thursday criticised the arrest of Mohta and said “no one is being spared in the Narendra Modi regime”. “They are arresting and are trying to intimidate everybody. Be it a writer, an actor, a film personality…. They don’t want to spare anyone. The people will give them a befitting reply,” TMC secretary general Partha Chatterjee said. The BJP has turned the CBI into their extended party office, Chatterjee claimed. Senior TMC leaders also alleged that the BJP is trying to pursue its vendetta politics through these arrests. SVF has denied the accusations and raised an objection. “We have full faith in the judiciary and it remains our endeavour to support and cooperate with the enforcement agencies in the course of their investigation,” a release said.last_img read more
