Along with Heng Pan, Sang Ryu, Nipun Misra and Costas Grigoropoulos at Berkeley, and Hee Park at AppliFlex in Mountain View, California, Ko believes that a solution may have been found. The team created a LIFT-based process called Nanomaterial Enabled Laser Transfer (NELT) in order to create direct patterning process resulting in a high resolution while transferring the organic light emitting diode (OLED) without damage. Their work is described in Applied Physics Letters: “Nanomaterial enabled laser transfer for organic light emitting material direct writing.”“NELT process can be used for any kinds of heat sensitive organic material direct patterning and transfer,” Ko explains. “NELT process can achieve more versatile laser wavelength selection with one or two order smaller laser energy than conventional LIFT processes by introducing a specially engineered nanoparticle layer as a laser absorbing and dynamic release layer.” Organic material is delicate, and can be easily damaged by intense heat from lasers. This is what makes the LIFT process, which relies on high temperatures for the proper pressure for transfer, of dubious worth in terms of advancing OLED technology.The nanoparticle layer is what mainly absorbs the laser wavelength. Because of its weak interaction with the organic material, there is less potential for damage. “[N]anomaterials exhibit remarkable properties that may be substantially different from those observed in the bulk counterparts,” Ko says. He also points out that the NELT process uses less energy than the LIFT processes currently considered conventional for direct writing.Among the more interesting applications for the NELT process is the possibility of flexible displays. “Flexible displays are built on flexible substrates so that they can be bent or folded just like a paper. They are futuristic displays usually found in the sci-fi movies.” Ko then continues with additional possible applications for this work: “Other applications include very large area organic light emitting diode display, active material transfer such as semiconducting polymer for organic field effect transfer for organic electronics, and biological material direct transfer for bio-sensor application.”Even with this advance, however, more is required, especially in terms of flexible display. Ko says that a transistor is needed in addition to the light-emitting portion of the display. “Currently we have successfully demonstrated a light emitting diode material direct patterning and transfer by NELT process and several direct writing methods for organic field effect transistor arrays on a polymer substrate. Now we plan to develop a novel approach to integrate organic light emitting diode and organic field effect transistor to demonstrate a working flexible display.”Science fiction may be moving a little closer to becoming science fact.Publication: Nanomaterial enabled laser transfer for organic light emitting material direct writing, Seung H.

Available online: link.aps.org/doi/10.1103/PhysRevLett.105.196102center_img (PhysOrg.com) — “Graphene offers a lot of interesting potential applications for nanoelectronics,” Florian Banhart tells PhysOrg.com, “but there is no band gap. This is a well-known problem. Without the band gap, switching as needed in electronic devices is difficult.” Banhart, a scientist at the University of Strasbourg in Strasbourg, France, believes that there is a solution to this problem. “Everyone tries to solve this problem, trying to create different properties in order to create a band gap. Our solution is doping with metal atoms attached to reconstructed defects in the graphene.”Working with Ovidiu Cretu and Julio Rodríguez-Manzo at the University of Stasbourg, and with Arkady Krasheninnikov at the University of Helsinki, Risto Nieminen at Aalto University in Finland and Litao Sun at Southeast University in Nanjing, China, Banhart developed a method to modify the properties of graphene. The group’s work is published in Physical Review Letters: “Migration and Localization of Metal Atoms on Strained Graphene.”“The idea is to be able to attach something to the surface of the graphene, changing some of the properties to get a band gap,” Banhart explains. By creating reconstructed defects, we can enhance the activity of the graphene and attach metal atoms firmly, possibly producing a band gap.”Banhart and his colleagues created graphene layers that were then damaged. “We used an electron beam to damage the graphene,” Banhart says. “For this paper, we used tungsten atoms to bond to the graphene. The defects we created made it possible for the tungsten atoms to be trapped by the defects, creating stable bonds.”Reconstructed defects increase the activity seen in graphene, making bonding to other atoms possible. “The graphene surface is normally rather inert,” Banhart explains, “but defects such as pentagonal or heptagonal rings enhance its activity. We saw enhanced chemical activity with the graphene.”Even though Banhart and his colleagues hope that this work will lead to the eventual creation of nanoelectronic devices made with graphene, he points out that they were unable to show definitive evidence of band gap creation. “There is no evidence that we did create a band gap,” he admits. “But perhaps tungsten is not ideal. We used it because it is large, and easy to see with the electron microscope when trapped by the graphene.”Banhart says that the tungsten has served its purpose, showing that it is possible to attach metal atoms to graphene with the help of defects on the graphene’s surface. He also points out that their recent work shows that it is possible to use this technique to modify graphene’s properties locally. “We have shown that our method might be used in the future to control graphene’s electronic properties better.”The next step is to try to trap other atoms using defects in graphene. Banhart would also like to do more tests on the electronic properties of graphene doped in this manner. “It would be good to do more tests of graphene,” he says. “With more experiments, we should be able to begin to model the electronic structure of graphene more accurately. Once we better understand the properties of graphene, we should be able to better manipulate them so that we can get a band gap, and so that we can use them in nanoelectronic devices.” This document is subject to copyright.

first_img Journal information: Proceedings of the National Academy of Sciences (Phys.org)—Gene expression plays a central role in the orchestration of virtually all cellular processes. While inducible promoters have proven invaluable in understanding regulatory networks by modifying gene expression levels, their use has faced some shortcomings. Specifically, their utility is constrained to research studying relatively short-term, population-scale effects. Recently, however, scientists at Institut National de Recherche en Informatique et Automatique (INRIA) and at Centre National de la Recherche Scientifique (CNRS), France, have demonstrated that implementing an external feedback loop allows single-cell gene expression to be accurately and tightly controlled over many generations. The team accomplished this by developing a real-time, closed-loop control gene expression platform integrating microscopy, microfluidics, and original software for automated imaging, quantification, and model predictive control. They state that their study demonstrates long-term control with both time-constant and time-varying target expression profiles, at the population and single-cell levels, shows that real-time control can limit the effects of gene expression stochasticity, and anticipate that their method will be useful for improving the performance of complex, synthetically engineered cellular networks. In Brief: Guiding cancer cells to their fate Explore further Citation: Focusing the phenotype: Controlling genetic expression through external feedback (2012, September 3) retrieved 18 August 2019 from https://phys.org/news/2012-09-focusing-phenotype-genetic-external-feedback.html Batt describes other innovations that might be developed and applied to the current experimental design. “With our setting, we trigger gene expression by applying osmotic shocks – that is, by changing the normal cell environment by a salt-rich or sugar-rich environment, and by highjacking the normal cell hyperosmotic response so that cells produce fluorescent proteins when shocked. Therefore, by design, all cells feel the same stimulation. Recently-developed novel optogenetic techniques allow individual stimulation of cells in a population: cellular processes can be activated or inactivated simply by exposing a cell to light. “The use of optogenetic techniques within our control platform should expand our control capabilities: each cell within a population could be controlled individually to fulfill the population objective.”To probe the functioning of dynamical systems, scientists generally observe how the system reacts following some perturbations – an approach that’s standard for studying the functioning of cellular processes. “However, current methods for perturbing protein levels – most notably the use of inducible promoters and RNA interference – are fairly limited in terms of duration and quantitative accuracy,” Batt points out. “Moreover, it is not possible to obtain well-controlled time-varying profiles of protein concentrations. Our platform for real-time control of gene expression has been developed precisely to address these limitations. “Synthetic biology aims at reprogramming cells so that they implement useful functions, and currently its typical target applications include biofuel production, bioremediation and even cellular therapies. In practice, bioengineers take advantage of the metabolic and information processing capabilities of cells to reengineer cells towards a desired objective. “However,” Batt comments, “it’s often nontrivial to implement robustly all functions using exclusively biological building blocks. By offering the possibility to use an external control loop, our project offers the possibility to develop mixed systems in which some elements are implemented in vivo using synthetic biology principles and some elements are implemented in silico using standard programming principles.”An important result of the research is that the findings provide evidence that real-time control can dynamically limit the effects of gene expression stochasticity. “We performed two types of experiments,” Batt notes, “In the first, we measured the fluorescence of all the cells in the microscope field of view, and used the mean cell fluorescence as a control criterion. In the second case, we only focus on one cell, randomly chosen at the beginning of the experiment, and defined the fluorescence of this cell as the control criterion. Then, we observed that the fluctuations around the target value of the fluorescence of a cell were statistically smaller when cells were individually controlled than when they were controlled as a member of a population.”In addition to systems and synthetic biology applications, Batt concludes, “Our platform can also be of interest to computational biologists, since it paves the way for online model selection and online model tuning.” In this setting, experiments are carried out, analyzed and interpreted in real-time, so that models can be challenged in the most efficient manner. Research Scientist Gregory Batt describes the challenges the research team faced in this study in designing an external feedback loop and platform to tightly control gene expression over many cell generations. “Because gene expression is a relatively slow process,” Batt tells Phys.org, “we had to do long-term experiments – each lasting 15 hours – to demonstrate the effective control of gene expression. Each experiment corresponded to many yeast cell generations, and every part of the platform had to be adapted accordingly.”For example, Batt continues, with the first microfluidic device they used, cells were directly under the flow of nutrient media. This allowed them to change the cells’ environment very rapidly, but when the cells divided, they were detaching from the bottom glass slide where they were “glued” and were then washed away. “We therefore had to adapt our device by making a type of trap where cells were protected from the main media flow.”In terms of original software for automated imaging, quantification, and model predictive control, Batt adds, the quantification of the protein concentration via the cell fluorescence measurements required particular attention. “Robustness was the issue here. Because we did real-time control, control decisions were made online. Therefore, all the steps of image analysis had to be done in a completely automated manner.” They therefore made a significant effort in developing robust routines for autofocus (to maintain good image quality over time), image segmentation (to detect the contours of all cells in the image), and cell tracking (to follow individual cells over time and detect newborn cells). “In particular,” notes Batt, “the imaging frequency had to be carefully chosen. Too many images are noxious for cells due to phototoxicity and photobleaching. On the other hand, too few images degrade the performance of autofocus and cell tracking.”In addressing these challenges, says Batt, “our key intuition was probably that automated control techniques and modeling will be effective enough to obtain quantitatively good performance despite the technological issues mentioned above – and even more importantly, despite the significant inertia and stochasticity of gene expression processes. Indeed, there is a significant lag between the initiation of the transcription on the chromosome and the effective increase of cell fluorescence. Transcription, translation, and protein folding take time.” More information: Long-term model predictive control of gene expression at the population and single-cell levels, PNAS August 28, 2012 vol. 109 no. 35 14271-14276, doi:10.1073/pnas.1206810109 Copyright 2012 Phys.org All rights reserved.

A platform for real-time control of gene expression in yeast. (A) A hyperosmotic stress triggers the activation and nuclear translocation of Hog1. Short-term adaptation is mainly implemented by cytoplasmic activation of the glycerol-producing enzyme Gpd1 and closure of the aqua-glyceroporin channel Fps1. Long-term adaptation occurs primarily through the production of Gpd1. (B) When maintained in a hyperosmotic environment (1 M sorbitol), the HOG cascade was quickly activated, which is seen by Hog1 nuclear enrichment. This transient signaling response lasted typically <20 min. (C) In contrast, the fluorescence level showed a continuous increase when stimulated periodically (T = 30 min). The increase rate was larger for longer pulses (red, 8 min; yellow, 5 min). (D) Yeast cells grew as a monolayer in a microfluidic device that was used to rapidly change the cells’ osmotic environment (blue frame) and image their response. Segmentation and cell tracking were done using a Hough transform (orange frame). (E) At the present time point (orange circle), the system state is estimated (green), and the Model Predictive Control (MPC) searches for the best input (pulse duration and number of pulses). Here, the osmotic series of pulses that corresponds to the blue curve (4) was selected and sent to the microfluidic command. This control loop is iterated every 6 min.

"Unfortunately, modeling is not trivial since gene expression is also a stochastic process. Confronted with the same stimulation, two cells do not respond identically. Even more problematic is the fact that the same cell confronted twice with the same stimulation does not respond twice the same." Therefore, notes Batt, the main open question at the beginning of the project was whether good performances could be obtained via model predictive control despite the significant inertia and stochasticity of gene expression processes.

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. (Phys.org) —Dutch designer Daan Roosegaarde has announced at Dutch Design Week, that he’s forged an agreement with Chinese officials to test a system he’s designed to clear smog from a small portion of the sky. Roosegaarde, with Studio Roosgaarde, is known for coming up with innovative design ideas that are good for both people and the environment. His latest idea involves embedding copper coils in the ground and running high voltage, low amp electricity through them to create an electrostatic charge strong enough to pull down smog particles in the air. Roosegaarde reported that he and his team have already built a running mock-up of the system at an indoor facility. There they are using the coils in a 5 x 5 meter smog filled room to create a 1 cubic meter round hole in the center that is free of smog. He likens the technology to the static electricity that occurs when people rub a balloon on their heads. With his system, the electrostatic charge would attract soot and other particles in the air in the immediate vicinity, making the air much easier to breathe.China, as most have heard, has been experiencing serious smog problems as coal fired electricity producing power plants release massive amounts of particles that sometimes cover cities in a haze that is both difficult to see through, and hazardous to health. The situation has at times become dire, Roosegaarde told those at the meeting, forcing officials to admit, albeit off the record, that something needs to be done in the short term, while long term plans are in the making. He disclosed that officials have granted him permission to install one of his systems in a public park in Beijing. It won’t happen right away of course, Roosegaarde and his team have to test a bigger system to work out the true design, and to make sure it will work outdoors. He insists the system will be safe, even for people walking directly over the coils.The coil system by Roosegaarde, even if it works exactly as planned won’t be the solution to the extreme smog problems in China, of course, but it might offer those in the area at least a temporary respite. If successful, it’s likely many such systems would be installed— Roosegaarde claims that the size of the hole in the smog is limited only by the amount of power sent through the coils.last_img read more

first_imgIn the new study, the researchers from Peking University demonstrated that it’s possible to efficiently build complex ICs on multiple CNTs, even though the CNTs have different properties. They did this using a modular approach, with the basic module being an eight-transistor (8-T) unit built on two CNTs with different electronic properties. The 8-T unit shows excellent tolerance to the property difference between the CNTs and can be used as a building block to fabricate the 8-bits BUS system, which contains 46 FETs on six CNTs. Tests showed that the 8-bits BUS system maintains a strong signal even as it passes through seven cascading logic gates.

The scale bar is 100 µm. Credit: Pei, et al. ©2014 American Chemical Society (Phys.org) —As silicon-based electronics are predicted to reach their absolute limits on performance around 2020, new technologies have been proposed to continue the trend in the miniaturization of electronic devices. One of these approaches consists of constructing field-effect transistors (FETs) directly on carbon nanotubes (CNTs). The resulting devices are on the scale of mere nanometers, although their fabrication is still a challenge. As the researchers explain, the method is particularly valuable now because it allows for exploration of the performance limits of CNT ICs while the material problems are still being solved.”This work has laid down a general way to construct complicated integrated circuits using currently non-perfect carbon nanotube materials, which (unlike silicon) are one-dimensional and different from each other,” Lian-Mao Peng, Professor at Peking University and coauthor of the new paper, told Phys.org.The 8-T unit can be used as the basic building block of a variety of ICs other than BUS systems, making this modular method a universal and efficient way to construct large-scale CNT ICs. Building on their previous research, the scientists hope to explore these possibilities in the future.”In our earlier work, we showed that a carbon nanotube based field-effect transistor is about five (n-type FET) to ten (p-type FET) times faster than its silicon counterparts, but uses much less energy, about a few percent of that of similar sized silicon transistors,” Peng said. “In the future, we plan to construct large-scale integrated circuits that outperform silicon-based systems. These circuits are faster, smaller, and consume much less power. They can also work at extremely low temperatures (e.g., in space) and moderately high temperatures (potentially no cooling system required), on flexible and transparent substrates, and potentially be bio-compatible.” New ‘doping’ method improves properties of carbon nanotubes Now in a new paper published in Nano Letters, researchers Tian Pei, et al., at Peking University in Beijing, China, have developed a modular method for constructing complicated integrated circuits (ICs) made from many FETs on individual CNTs. To demonstrate, they constructed an 8-bits BUS system—a circuit that is widely used for transferring data in computers—that contains 46 FETs on six CNTs. This is the most complicated CNT IC fabricated to date, and the fabrication process is expected to lead to even more complex circuits.Ever since the first CNT FET was fabricated in 1998, researchers have been working to improve CNT-based electronics. As the scientists explain in their paper, semiconducting CNTs are promising candidates for replacing silicon wires because they are thinner, which offers better scaling-down potential, and also because they have a higher carrier mobility, resulting in higher operating speeds. Yet CNT-based electronics still face challenges. One of the most significant challenges is obtaining arrays of semiconducting CNTs while removing the less-suitable metallic CNTs. Although scientists have devised a variety of ways to separate semiconducting and metallic CNTs, these methods almost always result in damaged semiconducting CNTs with degraded performance. To get around this problem, researchers usually build ICs on single CNTs, which can be individually selected based on their condition. It’s difficult to use more than one CNT because no two are alike: they each have slightly different diameters and properties that affect performance. However, using just one CNT limits the complexity of these devices to simple logic and arithmetical gates.

Its lowest point is 10,994 meters below sea level. It is located southwest of Japan, and has been an area of scrutiny ever since the development of underwater pilotless craft called Remotely Operated Vehicles (ROVs). Prior research has shown that the trench formed due to the Pacific tectonic plate sliding beneath the Philippines plate, making it a subduction zone. In this new effort, the researchers used an ROV to extract 46 samples of serpentine from the ocean floor near the South Chamorro mud volcano, which they brought back to their lab for study.Serpentine is a mineral that forms when olivine in the upper mantle meets water pushed up from a subduction zone. Such reactions produce methane gas and hydrogen, which the researchers note could be used as a food source by microbes. Serpentine is pushed to the surface of the sea floor by hydrothermal vents, where the researchers found it.Upon examination of their serpentine samples, the researchers found trace amounts of organic material that was very similar to that produced by microbes living in more accessible places. That suggests, the team notes, it is possible that the serpentine samples are evidence of life living far below the surface. The team used data from prior studies to calculate how far below the sea floor the serpentine was formed, which allowed them estimate just how far down the possible microbes might live—approximately ten kilometers below the sea floor.The team acknowledges that their findings are not proof of life below the sea floor; other processes have been known to produce both serpentine and the organic matter, but, they note, it does suggest it is possible.center_img More information: Oliver Plümper et al. Subduction zone forearc serpentinites as incubators for deep microbial life, Proceedings of the National Academy of Sciences (2017). DOI: 10.1073/pnas.1612147114AbstractSerpentinization-fueled systems in the cool, hydrated forearc mantle of subduction zones may provide an environment that supports deep chemolithoautotrophic life. Here, we examine serpentinite clasts expelled from mud volcanoes above the Izu–Bonin–Mariana subduction zone forearc (Pacific Ocean) that contain complex organic matter and nanosized Ni–Fe alloys. Using time-of-flight secondary ion mass spectrometry and Raman spectroscopy, we determined that the organic matter consists of a mixture of aliphatic and aromatic compounds and functional groups such as amides. Although an abiotic or subduction slab-derived fluid origin cannot be excluded, the similarities between the molecular signatures identified in the clasts and those of bacteria-derived biopolymers from other serpentinizing systems hint at the possibility of deep microbial life within the forearc. To test this hypothesis, we coupled the currently known temperature limit for life, 122 °C, with a heat conduction model that predicts a potential depth limit for life within the forearc at ∼10,000 m below the seafloor. This is deeper than the 122 °C isotherm in known oceanic serpentinizing regions and an order of magnitude deeper than the downhole temperature at the serpentinized Atlantis Massif oceanic core complex, Mid-Atlantic Ridge. We suggest that the organic-rich serpentinites may be indicators for microbial life deep within or below the mud volcano. Thus, the hydrated forearc mantle may represent one of Earth’s largest hidden microbial ecosystems. These types of protected ecosystems may have allowed the deep biosphere to thrive, despite violent phases during Earth’s history such as the late heavy bombardment and global mass extinctions.

first_imgAmish Tripathi talks to Poulomi Banerjee about the Oath of the Vayuputras and life beyond the Shiva trilogyhology…After Immortals of Meluha was released, you had said, that you had the other two parts too planned in your mind… writing the second (The Secret of the Nagas) and the third (The Oath of the Vayuputras) books must have been easy then.As far as I am concerned, the Shiva trilogy is one continuous story and not three separate books. But it is difficult to bring out such a long story as one book, and hence the format of the trilogy. Even before the release of the 1st book, I had the complete story in mind, right down to the last line. But when you are in the actual process of writing, characters and sub-plots get introduced and the challenge then is to blend them with the main storyline. Also Read – ‘Playing Jojo was emotionally exhausting’Also, since the Oath of the Vayuputras was the final book of the trilogy, I had tie up all the loose ends. But the fact, that the story is one uninterrupted thought would be evident to anyone who has carefully read the book. In each of the books, I have left clues about what was going to happen in the next one.As a writer, what was the most difficult decision that you had to take in the Oath of the Vayuputras?Some characters had to die, and to kill them was the most difficult task I had to perform. Also Read – Leslie doing new comedy special with NetflixYou have said that you were an atheist and the Shiva Trilogy was for you a blessing that changed you as a person. Having spent so much time telling this story, are you in anyway sad that the book is done with the release of the Oath of the Vayuputras?The book is done, but my relationship with Lord Shiva continues. I have become a believer for life. So there is no sadness at all. There is a sense of completeness.The last line of the Oath of the Vayuputras mentions the Mahabharata and says that story too will be told some days… Is that a hint to your readers? Is your next book going to be on Mahabharata?No. I have many ideas for my next book series, but I am yet to finalise the one I will take up. The Mahabharata, is one of the ideas under consideration. All the ideas that I am toying with are again based on history and mythology for that is my area of passion.The Immortals of Meluha is being made in to a film. Tell us about the progress on that front.Well, as you know, Karan Johar has acquired the film rights for the book and his team is working on the script. Once the script is ready, they will start work on the cast and other details.And you have not involved yourself with the script?No, it was a conscious decision on my part to not get involved in the script-writing, since I have felt that I can’t do justice to it and write my book at the same time, and I had to complete the Oath of the Vayuputras.With the Shiva Trilogy you have created not just a successful story, but also a successful marketing model. What was the vision that you had when you started marketing the book and why did you often choose smaller bookshops for launches and events rather than bigger bookstore chains?I’ve always believed that it is a fallacy to assume that a good book sells itself. That’s not true. A bad book and good marketing doesn’t work. But then, a good book and bad marketing does not work either.Both the book and the marketing need to be good. My team and I have implemented a lot of innovative ideas to promote my books and I’m glad that they have been well received.In book, you have often included modern issues such as widow remarriage, caner… then what would you say is evil, a subject that you dwell upon in detail in the Shiva trilogy, in today’s socio-political scenario?I’d love to answer this question, but then I may end up giving away the philosophy that is to be explained in the 3rd book. That may spoil the book for those who haven’t read the 3rd book. Perhaps I’ll answer this question six months later.last_img read more

Come Sunday and KoPT will take you on a heritage tour on board its vessel to explore various places in and around river Ganga, most of which have been shielded from public view.”Kolkata Port is intrinsic with the history of Kolkata and we feel that remembering Kolkata’s glorious past cannot be without having knowledge about the port that was officially born 147 years ago. We have set up a museum at the Fairley Warehouse, an early 20th century peer of the Strand Warehouse that was lost in a fire on February 14, 2010, which will throw light at various landmark memories associated with the port. Our heritage tour will begin right from there,” KoPT chairman Vinit Kumar said. Also Read – Heavy rain hits traffic, flightsElaborating on the tour, Kumar said that the three and half hour journey will start from the museum and then visitors will be taken to Princep Ghat, from where they will board a vessel. “We will be taking them on a guided tour of various jetties and constructions on the bank of river Hooghly. The tour will end at the Indenture Memorial,” Kumar said.The Indenture Memorial has been set up at the Suriname Jetty. It was from this place that the indentured workers from India set sail in ships to the small country located on the north-east Atlantic coast of South America from 1873 to 1910.

It symbolises the first Indian man and woman to set foot in the Dutch-speaking nation.”How many of us know the jetty where Sister Nivedita had landed or that Uttam Kumar was an employee of KoPT, or have witnessed a piece of important history of the city overlooked by a tower peaked by a Cooke and Kelvey turret clock dating back to 1899? All these will be part of the tour,” Kumar added.The tour will be conducted weekly. The rate per person will be Rs 1,399, while that for foreigners will be Rs 2,499 each, including refreshments.last_img read more

first_imgKolkata: In a tweet on the occasion of Earth Day, Chief Minister Mamata Banerjee has urged people to put an end to plastic pollution to ensure a clean environment.”On the occasion of Earth Day, let us pledge to keep our environment clean. We can take a step in this direction by putting an end to plastic pollution,” Banerjee tweeted on Sunday morning.Earth Day 2018 is dedicated to providing the information and inspiration needed to change human attitude and behaviour about plastics fundamentally. Also Read – Heavy rain hits traffic, flightsOne of the bleakest stories of the year so far was the report of a six-ton sperm whale washing up on the shores of southern Spain with 64 pounds of plastic in its stomach, a disturbing sign of the alarming rate at which we’re dumping plastics into the ocean.The plastic crisis is a truly global one, and the numbers are staggering: A 2015 study found that between 4.8 and 12.7 million metric tons of plastic make it into the ocean from land each year. By 2050, there will be more plastic than fish in the ocean by weight.Since plastic is synthetic, few natural processes break it down, allowing bags, straws, and packaging to linger for decades if not centuries. And we’re not very good at containing it to landfills. About 32 percent of plastics make out into nature, where it often ends up in the bellies of fish, birds, and whales. And, as it turns out, potentially in our stomachs too.last_img read more

first_imgThein Sein, a former general who has run Myanmar since 2011 when the junta ceded power to a quasi-civilian government after decades of brutal rule, insisted his country was on the path towards genuine democracy.“Our reform process is going step by step. There is no backsliding. We are now on the track towards democracy, but going at a steady pace,” he said in a BBC interview broadcast today. He also said the army needed to be “involved in national politics” and refused to commit himself to any specific timetable on when that political role might be reduced.

But some observers fear his initial enthusiasm has stalled.The NLD is expected to win this years elections if polls are free and fair.But Suu Kyi cannot stand for the presidency because a clause in the constitution bans those with a foreign spouse or children.

first_imgIn an interview, the 26-year-old flight attendant known as Maria W told Bild that when she heard about the crash she recalled Andreas Lubitz telling her last year: “One day I’m going to do something that will change the whole system, and everyone will know my name and remember.”The black box voice recorder indicates that Lubitz, 27, locked his captain out of the cockpit on Tuesday and deliberately flew Flight 4U 9525 into a mountainside, French officials say, in what appears to have been a case of suicide and mass killing. French Prime Minister Manuel Valls said that all the signs were “pointing towards an act that we can’t describe: criminal, crazy, suicidal”. German prosecutors revealed that searches of Lubitz’s homes netted “medical documents that suggest an existing illness and appropriate medical treatment,” including “torn-up and current sick leave notes, among them one covering the day of the crash”. They did not specify the illness. According to Bild, the young woman, who was “very shocked”, flew with Lubitz on European flights for five months last year, during which time they are believed to have been romantically involved. If Lubitz did deliberately crash the plane, “it is because he understood that because of his health problems, his big dream of a job at Lufthansa, as captain and as a long-haul pilot was practically impossible,” she told Bild. The pair separated “because it became increasingly clear that he had a problem”, she told the daily, adding that at night he would wake up and scream “we’re going down” and was plagued by nightmares.Bild earlier reported that Lubitz sought psychiatric help for “a bout of serious depression” in 2009 and was still getting assistance from doctors, quoting documents from Germany’s air transport regulator.last_img read more

first_imgOne of the world’s top three music festivals, Sunburn Goa returns this year as a prelude to its 10th anniversary in association with Goa Tourism. It will begin from December 27 at Vagator Beach, Goa.Spearheading the performance on the first day of the festival is David Guetta, who is ready to surprise the audience once he steps on the stage. He revealed to Millennium Post that he is planning to go against the established EDM format and create new formulas by combining different genres of music.  Also Read – ‘Playing Jojo was emotionally exhausting’He is busy experimenting and is currently attempting to combine urban rhythms with electronic music. Here’s an easy one. What are the five things you cannot live without? Five is tad too long! Let’s make it just two, my laptop and my manager.How excited are you, now that you are playing in this country for the third time? Well India always holds a very special place in my heart. It’s always thrilling to see your fans all over again and surprise them with some classics. Also Read – Leslie doing new comedy special with NetflixWhat do you plan to do in Goa other than your performance in ‘Sunburn’? I’ll just be flying in, taking a nap at the hotel and heading straight to my gig. In case I do catch up on sleep on the flight, I may go look around a little. This is my third visit to Goa!What are the tracks you will be playing at ‘Sunburn’? How different will they be from the previous performances? Let’s say it’s all a surprise, but it’s Guetta Reloaded! I feel I have a responsibility towards my fans and I feel the urge to surprise them each time I come up on the stage. It’s more motivating. You have been selected to create the anthem of UEFA Euro 2016 tournament and recently, there was a buzz that you want football aficionados and their music to be in the core of the track… How far have you progressed? I’m so excited to be working towards uniting fans in Europe. UEFA EURO 2016 is all about the fans and I want to put them at the heart of everything, especially the song. Music, like sport brings people together, so I’m trying something very special and asking people around the world to unite and add their voices to this anthem.You have collaborated with so many artists across the world, who is the next artist you’ll be working with? I started a record with Hozier, and I would really love to get back in the studio with him. His record was the most amazing one of 2014. It was so full of emotion, and my thing is to combine emotion with the energy of dance music. That was always my winning ticket, if I could say, my trick to have dark, emotional elements and also happy, energetic elements together.Where do you see yourself ten years from now? DJing on the moon maybe! On a serious note, I’d love to get new producers discovered and introduce a brand new sound. DJing is a different job now. When we do a show, it’s a concert, and we’re selling ourselves as artists and not DJs. Now I’m trying to look for a way to go against the established format again because I think the essence of dance music is to go against formats.I think the challenge of the upcoming year for dance music is to go against our own format. It’s like we came such a long way to get there and be respected as much as hip-hop and rock, but now what are we going to do with it? I’m trying to combine urban rhythms with electronic music.EDM was super-exciting because it was so new and different. And now I feel the need to change the formula again, you know? I am making a lot of new music at the moment. It’s an exciting time for me again. The success of Hey Mama is great because it makes me want to create more records like this.last_img read more

first_imgKolkata: She is not only a mother, but a gritty woman who pulled out all stops to become the countrys first female unrelated bone marrow donor to give new lease of life to an ailing three-month-old infant, doctors claimed. It took a lot of courage for the 26-year-old Masilamani, hailing from a nondescript village of Coimbatore in Tamil Nadu, to come out and donate her bone marrow to save a baby from New Delhi. Masilamani, the mother of a thalassemia major girl, was in the city on a personal visit. Also Read – Bose & Gandhi: More similar than apart, says Sugata Bose She is ecstatic at what she has achieved recently. “I believe Im blessed. I managed to break away from the misconceptions of our society to save a child. I feel like I am the mother of the child. I would say it is my child too as now I have given him a second chance to live. I pray to the almighty that he must recover fast and should never suffer again. He must be healthy,” Masilamani told PTI. Talking about her fight against social myths when she decided to go ahead with the bone marrow donation, Masilamani recalls, “My village is a very remote one at the foot of the Velliangiri hills with very less exposure to any modern amenities. There are very few educated people there. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata Therefore, anything new, be it a thing or a thought, is always resisted in the village.” Hailing from Mudhalipalayam, a hamlet in Coimbatore, Masilamani got married at the age of 20 to R Kaviarasan, a fabricator. “Within a year, my daughter was born and a few months later she was diagnosed with thalassemia major. We both (husband and wife) have our swabs to identify human leukocyte antigen (HLA) to check if we could be of any match to our daughter at DATRI – the blood stem cells donor registry. There I found a match to become a donor for a baby boy.” Excited but confused, Masilamani shared the piece of information with her husband who agreed that it was a great opportunity to help another parent in distress. But we could not take a decision so easily. My mother-in-law and sister-in-law resisted saying if something went wrong, who will take care of your children? “The in-laws were all the more worried as I have a daughter with a chronic illness. Even my relatives and neighbours advised me not to go ahead with the donation as there could be side effects in the future, if not immediately. I was confused,” Masilamani said. Masilamani, who gave birth to a boy three years later, sought expert advice on bone marrow donation. “My doubts were cleared and I was glad to know there are no short-term and long-term side effects. I could finally convince my family and take a decision to donate bone marrow to save a life,”she says. Masilamani thanked her husband profusely for supporting her when it mattered most. “There are men who would leave their partners if the child is found to be having any such fatal disorder. But Kaviarasan has been a responsible father and a great partner,” she said. Describing bone marrow donation as a simple process without side effects, Masilamani hopes that her act would encourage other women to come forward. “I understand that women have more compulsions to back out from donations than men. But I am an example that nothing is big enough to stop us from gifting a life. After undergoing the procedure, I can vouch that it is very simple and has no side effects. Many people discouraged me saying you may not walk properly, you may get bedridden, marrow will be taken from spine etc,” she pointed out. Asked if she was willing to donate again, Masilamani said she would be more than happy to do it. “They say the greatest gift is the gift of life and it is a golden opportunity to gift it if you are found to be a match. I will definitely donate”. As of now, India has a total of 1,36,244 female donors, which is about 34 per cent of the total registered donors, official data say. The total number of women who backed out from donations in the last two years (January 2017 to February 2019) were 129, according to DATRI data. “I feel privileged to have Masilamani as Indias first lady bone marrow donor from DATRI. It makes me proud to say that while women are excelling in every field, there are a few who are doing extraordinary and phenomenal contributions to the human kind such as donating their blood stem cells to save lives. In the true sense, it is like giving birth, but not biologically,” DATRI founder and CEO Raghu Rajagopal said. DATRI is engaged in finding willing matched donors for patients suffering from fatal blood-related disorders and in need of a blood stem cell transplant,last_img read more

first_imgMen who eat leafy greens, dark orange and red vegetables, berries and drink orange juice may be at a lower risk of developing memory loss in older age, according to a study The findings showed that men who ate larger amounts of fruits and vegetables 20 years earlier were less likely to develop thinking and memory problems, whether or not they kept eating larger amounts of fruits and vegetables later. Men who consumed the most vegetables were 34 per cent less likely to develop poor thinking skills than the men who consumed the least amount of vegetables.

Participants also took subjective tests of their thinking and memory skills at least four years before the end of the study. A total of 55 per cent of the participants had good thinking and memory skills, 38 per cent had moderate skills, and seven per cent had poor thinking and memory skills. However, the study does not show that eating fruits and vegetables and drinking orange juice reduces memory loss.last_img read more
