Scientists grow solar cell components in tobacco plants

first_imgScientists are working on synthesizing solar cells from chromophore structures they produced in tobacco plants. Image credit: US Department of Agriculture. © 2010 PhysOrg.com Scientists grow insulin in tobacco plants In a recent study, scientists from UC Berkeley led by Matt Francis have demonstrated how to program tobacco plants to take advantage of the efficient way that they collect sunlight. Rather than attempt to reprogram all the cells of a mature tobacco plant, the scientists genetically engineered a virus called the tobacco mosaic virus to do the job for them. The researchers sprayed the modified virus on a crop of tobacco plants, and the virus caused the plant cells to produce lots of artificial chromophores, which turn photons from sunlight into electrons.In order for the chromophores to work, however, they must be spaced at a precise distance from one another – about two or three nanometers. A little closer or further apart, and the electric current will either be halted or the electrons will be very difficult to harvest. Thankfully, tobacco plant cells have evolved to space chromophores at this exact distance, lining them up in a long spiral hundreds of nanometers long. By exploiting this structure, the researchers could take advantage of billions of years of evolution to grow perfectly spaced strands of chromophores. “Over billions of years, evolution has established exactly the right distances between chromophores to allow them to collect and use light from the sun with unparalleled efficiency,” said Francis.Since the modified tobacco plants themselves don’t generate electricity, the researchers must harvest the plants and extract the chromophore structures. Then, the scientists can dissolve the structures in a liquid solution, and then spray the solution on a glass or plastic substrate to create a solar cell. So far, the scientists have not yet demonstrated that the resulting solar cells can turn light into electrical energy.Compared with traditional solar cells, those made from plants could have several potential advantages. For instance, they don’t require the use of toxic chemicals, they’re biodegradable, and they’re inexpensive to produce. On the other hand, bio-based solar cells would likely have a shorter lifetime than silicon solar cells.In addition to using tobacco, the researchers also demonstrated how to manipulate E. coli bacteria to produce chromophore structures. In this case, the researchers didn’t use a virus, but modified the bacteria directly. More information: Michel T. Dedeo, Karl E. Duderstadt, James M. Berger and Matthew B.

Donated Chinese bamboo strips turn out to be ancient multiplication table

first_img © 2014 Phys.org Citation: Donated Chinese bamboo strips turn out to be ancient multiplication table (2014, January 9) retrieved 18 August 2019 from https://phys.org/news/2014-01-donated-chinese-bamboo-ancient-multiplication_1.html The bamboo strips were part of a much larger collection of very old and partially decomposed bamboo strips, all of which had writing on the back. Recently, the researchers separated out the strips that had numbers on the back instead of characters representing letters. Figuring out what the numbers meant was a time-consuming process as they were in random order—the string that once bound them together had decayed thousands of years before. The time during which they were created corresponds to a period just before the Qin Dynasty, when what is now known as China was still divided into several warring states. Each strip is approximately 20 inches long and slightly less than half an inch wide, and the collection is believed to have been part of a set of artifacts retrieved from an ancient tomb which was subsequently lost to illegal trafficking. The person that donated the collection to university had bought it at a market in Hong Kong.Lining the strips in the right way reveals a table very much like a modern multiplication table—numbers across the sides and tops are used as multiplicands, their intersection points mark the result. Interestingly, the table also allows for multiplying partial numbers between 0.5 and 99.5, though the process requires converting equations into sums first.The researchers believe the multiplication table was likely used to measure land area, or to predict crop yields. They note the table can also be used to solve division problems, but doubt the people using them had learned of such math at the time. Prior to the new discovery, the oldest known multiplying device found in China was a table dated back to a period a couple of hundred years later than this new table, and it was considerably less useful. The new bamboo table represents a level of mathematical sophistication unheard of for the time, meaning historians will have to revise their estimates of the skill levels of the people that invented the table.

No ink required paper can be printed with light

first_img Various samples of the light-printable paper. Credit: Wang et al. ©2017 American Chemical Society Rewritable material could help reduce paper waste The researchers, Wenshou Wang and coauthors at Shandong University in China; the University of California, Riverside; and Lawrence Berkeley National Laboratory, have published a paper on the light-printable rewritable paper in a recent issue of Nano Letters.”The greatest significance of our work is the development of a new class of solid-state photoreversible color-switching system to produce an ink-free light-printable rewritable paper that has the same feel and appearance as conventional paper, but can be printed and erased repeatedly without the need for additional ink,” Yadong Yin, Chemistry Professor at the University of California, Riverside, told Phys.org. “Our work is believed to have enormous economic and environmental merits to modern society.”Currently, paper production and disposal have a large negative impact on the environment: paper production is a leading source of industrial pollution, discarded paper is a major component (approximately 40%) of landfills, and even recycling paper contributes to pollution due to the process of ink removal. There is also the issue of deforestation: in the US, about one-third of all harvested trees are used for paper and cardboard production.Working to address these problems, researchers have been investigating alternatives to disposable paper. One possibility is to take advantage of the color-switching ability of certain chemicals when exposed to light, although in the past this approach has faced challenges in terms of stability, limited reversibility, high cost, toxicity, and difficulty in applying the coating to ordinary porous paper.The light-printable paper developed in the new study improves in all of these areas, bringing the technology closer to applications, which could include any medium on which information is printed and needed for only a short time.”We believe the rewritable paper has many practical applications involving temporary information recording and reading, such as newspapers, magazines, posters, notepads, writing easels, product life indicators, oxygen sensors, and rewritable labels for various applications,” Yin said. When the Prussian blue and TiO2 nanoparticles are evenly mixed and coated onto paper, the plain unprinted paper appears solid blue. To print text or images, the paper is exposed to UV light, which photoexcites the TiO2 nanoparticles. These nanoparticles then release electrons that are picked up by the adjacent Prussian blue nanoparticles, which turn from blue to colorless. Since it’s easier to read blue text on a colorless background than colorless text on a blue background, it’s the background rather than the text that is typically printed by light, turning colorless (although the paper can also be “reverse-printed” to show colorless text on a blue background). Different colors besides blue can also be achieved by using Prussian blue analogues of various colors.Once printed, the paper retains its configuration for at least five days with high (5-µm) resolution, and then slowly fades back to solid blue through oxidation under ambient conditions. To erase the paper more quickly, the paper can be heated for about 10 minutes to return it to its solid blue state. The researchers predict that light-printable paper will be inexpensive when produced on a commercial scale.”The light-printable paper is indeed cost-competitive with conventional paper,” Yin said. “The coating materials are inexpensive, and the production cost is also expected to be low as the coating can be applied to the surface of conventional paper by simple processes such as soaking or spraying. The printing process is also more cost-effective than the conventional one as no inks are needed. Most importantly, the light-printable paper can be reused over 80 times, which significantly reduces the overall cost.”Future plans focus on bringing the technology closer to practical use.”Our immediate next step is to construct a laser printer to work with this rewritable paper to enable fast printing,” Yin said. “We will also look into effective methods for realizing full-color printing.” Citation: No ink required: paper can be printed with light (2017, February 2) retrieved 18 August 2019 from https://phys.org/news/2017-02-ink-required-paper.html Journal information: Nano Letters Explore further (Phys.org)—In an effort to curb the adverse environmental impacts of paper production, researchers in a new study have developed a light-printable paper—paper that can be printed with UV light, erased by heating to 120 °C (250 °F), and rewritten more than 80 times. The secret to printing with light lies in the color-changing chemistry of nanoparticles, a thin coating of which can be easily applied to conventional paper to transform it into the light-printable version. © 2017 Phys.org Light-printable rewritable paper showing a quote by Richard Feynman. Credit: Wang et al. ©2017 American Chemical Society The new coating consists of two types of nanoparticles: those made of Prussian blue, which is a common inexpensive, nontoxic blue pigment that turns colorless when it gains electrons; and titanium dioxide (TiO2), a photocatalytic material that accelerates chemical reactions upon UV light exposure.

Evidence that humans prefer genetically dissimilar partners based on scent

first_img © 2019 Science X Network Explore further Prior research has shown that animals, including humans, are more successful from a genetic perspective when they mate with a partner that is genetically dissimilar in key ways. One of those differences is the makeup of their MHC—a cluster of genes that plays an important role in immune function. When two people with dissimilar clusters mate, their offspring gain the benefits of both parents. In recent years, medical researchers have suspected that people are able to “sense” the makeup of a potential mate’s MHC, and that people tend to find those with dissimilarities more attractive. It was assumed that if this were the case, that the olfactory system was responsible. The researchers with this new effort note that several studies have been conducted that were designed to determine if such theories were correct, but the results have varied widely. To find out once and for all, they conducted a larger, more thorough study.The work involved analyzing data from the Database of Genotypes and Phenotypes managed by NIH. The researchers report that they were able to use genome-wide data from over 800 couples living in Europe and the Middle East (Israel)—more specifically, they were able to see how similar their MHCs were.The researchers report that on average, the MHCs between couples in Europe were dissimilar—more so than could be accounted for by randomness. They also noted that such differences were the most pronounced in couples living in the Netherlands. But they also report that they found no such degree of dissimilarity for couples living in Israel.The researchers suggest their findings provide strong evidence of a human ability to smell MHC in other humans and to prefer mates with dissimilarities. They suggest such a preference can be overridden by cultural practices, however, such as those found in Israel, where mate choice is limited due to social standing or family practices. Journal information: Proceedings of the Royal Society B Credit: CC0 Public Domain Opposites attract — how genetics influences humans to choose their matescenter_img A team of researchers at Université Paris Diderot has found evidence that suggests humans are able to detect via smell which partners are genetically preferable.

Suu Kyis second time round

first_imgThe Indian Institute of Advanced Studies (IIAS), a research institution in Shimla, has published another edition of Myanmar’s pro-democracy icon Aung San Suu Kyi, the institute’s official said on Friday. ‘The second edition of Suu Kyi’s book Burma and India: Some Aspects of Intellectual Life under Colonialism has been brought out as a paperback edition and is priced at Rs 195,’  IIAS director Peter Ronald Desouza said in a statement. The bookis based on the manuscript Suu Kyi submitted after completion of her fellowship at the IIAS in 1987. The book, first published in 1990, is about comparative study of intellectual life under colonialism in the two countries. It describes the varying responses of India and Burma during British colonialism, responses which reflect the changing social structure and character of the two societies. It also discusses the Buddhist influence from India on Burma and the inability of Burmese society to resist the colonial onslaught in contrast to India, which developed a more substantial response. The opposition leader of Myanmar stayed at the IIAS with her husband Michael Aris, who was also a fellow, and their two sons. ‘It was through the ambassador of India to Burma that Suu Kyi could be sent the re-typed and proof-read version of her book to make the necessary changes, which she did,’ Desouza said. ‘She chose the cover design,’ he added. On the request of Suu Kyi, he said, IIAS would send some copies of the book to public libraries and universities across India. The IIAS is a premier advanced research institution in the field of humanities and social sciences.last_img read more

Con Banega Crorepati

first_imgIt is not everyday that you see Dilliwallahs jostle to take a look at books. And buy them by the dozen. The Book Fair has been going mostly empty. But if you had been going to Dilli Haat over the last weekend, you would see how the place has completely transformed. All thanks to the Third Annual Comic Con. Every Delhiite worth his Diamond Comics came along. If not to buy books, to browse through them. If not to browse, then pick up merchandise. And if for nothing else, then to get themselves clicked with the quirky banners and with men and women who decided to give themselves a fun makeover. Also Read – ‘Playing Jojo was emotionally exhausting’Of course Comic Con is about comics. But it is as much about the merchandise, some of which you will get only at Comic Con which makes them all the more attractive for the funk-loving youngsters. And funky they all are. Superkudi, that hit theme of the last edition of Comic Con, has given way to Supermummy this year. So apart from banners, you could also pick up Supermummy tees, posters, wall clocks, cushions and even mugs. The ‘Wonder Bai’, or the ubiquitous Indian maid, was another favourite. Also Read – Leslie doing new comedy special with NetflixBut what most people were seen jostling for (and some even went back disappointed since most stalls had run out of sizes) were the Superman and Batman tees. While some were the more regular ones, there were others which had been fun slogans. The Bangalore-based Hysteria, was seen doing brisk business with their badges, posters, tees, art prints and more. So much so, that you actually had to queue up to see their poster catalogue. While the now well-known Chumbak (every girl worth her auto raja boxers have heard of them) has a stall, we found the lesser known ones doing brisk business. The merchandise was similar — tees, mugs, quirky posters, calendars and even toys of comic characters — but each added their own quirky take to them. Want to voice an opinion? Wear it on the tee. That was the USP of the Wear Your Opinion stall. A stall which stocked Harry Potter merchandise, was also a crowd favourite.last_img read more

Indias little Poland

first_imgThis is a story of a long ago. When World War II left Poland ravaged and thousands of Polish people homeless, about 1000 children from war-torn, occupied Poland and Soviet prison camps in Stalin’s Siberia, travelled all the way to India, where Jam Sahib, Digvijaysinhji Ranjitsinhji Jadeja of Nawanagar, nephew of famous Indian cricketer Ranjitsinhji Vibhaji of  the Jadeja clan, a princely state in the Kathiawar Peninsula, took personal risks to make arrangements at a time when the world was at war and India was struggling for its independence. He built a camp for them in a place called Balachadi beside his summer palace, 25 km from his capital city Jamnagar. Also Read – ‘Playing Jojo was emotionally exhausting’The children stayed in the camp for four years (1942 to 1946), picking up pieces of their lives, making happy memories till they got to reunite with their family and friends when Polish history reached peaceful times.After years, documentary film maker, Anu Radha and Sumit Osmand Shaw have got The Survivors of Balachadi, as they like to call themselves, together, to make a heart-touching piece of narrative A Little Poland in India.

No need to go out of state bright career possible in Bengal

first_imgKolkata: State Education minister Partha Chatterjee said that students no longer need to venture out of the state for higher studies and assured them of a bright career in the state itself.”Some of the students have a misconception that they will not be able to make it big in Bengal and have to have the stamp of foreign countries. Bengal has seen a sea change in the education scenario. As many as 18,000 students from other states have come to Bengal this year for higher studies. We have as many as 4.5 lakh seats in our colleges and universities. So, they should come out of the misconception that they will be unable to manage a good career here,” Chatterjee said, while distributing scholarships to 51 toppers of Madhyamik Examination 2018, across 23 districts of Bengal. This was done as a part of the Jahar Lal Chandra Merit Scholarship Programme of a well known jewellery group. A scholarship of Rs 50,000 each was handed over to the students. Chatterjee made it clear that clearance from the state government will be mandatory now for setting up schools. “We will cancel the affiliation of any school that will be found running without our clearance certificate,” he added. The Education minister also unveiled the government’s plan of setting up two new universities at North 24-Parganas and Nadia.last_img read more

Those making the commitments included Reliance Industries chairman Mukesh Ambani, who said it was nothing short of a “miracle” that the state has adopted a change in mindset to welcome the industry. Banerjee said 50 per cent of the investment proposals made at the last year’s event were already in progress and asserted that Bengal was the new investment destination because of political stability, industry-friendly environment and also because of its strategic location. Major business groups which announced investments at the summit also included Adani Group, JSW group, Adventz group and RP-Sanjiv Goenka group. The Summit saw participation from 32 countries, though there was no representation from the central government. According to the state government, several MNCs including Dassult, Aramco, Samsung and PepsiCo have also expressed business interest. Later in the year, Banerjee announced a 200-acre plot at New Town, dedicated for a silicon valley hub for high-end IT functions. Already, companies like Jio, TCS and Capgemini have applied for land parcels there. The booming e-commerce business also left its mark in the state this year. Flipkart subsidiary Instakart Services would invest Rs 991 crore at Haringhata, about 55 m from Kolkata, for a logistics park with employment potential in excess of 18,000 people. Software Technology Parks of India (STPI) would invest around Rs 120 crore for a single project with the objective to delivery technological services in the east and north-east with the idea to boost software exports. The state also got a shot in the arm on getting exploration and licensing of Deocha-Pachami coal block in Bankura district with an aggregate reserves of over 21 million tonnes. City-based storage battery major Exide Industries also announced an investment of Rs 550 crore for two projects in the state this year. Praise also came from a group of 13 senior economists, including former RBI Raghuram Rajan and IMF Chief Economist Gita Gopinath, when they cited example of West Bengal while outlining an economic strategy for India. Talking about need to reform the healthcare system in India, the group said studies in West Bengal suggest that training the private sector health providers improves their performance by a very significant amount. They said West Bengal has already begun to train many thousands of private sector health providers and it would make sense for other states to follow the same. However, there were also warnings from some quarters about the risks from climate change. A study by New Delhi-based climate research group Climate Trends listed West Bengal among the estates facing heightened risks from multiple climate disasters.last_img read more

In Ireland a Pint of Guinness Used to be Handed out for

first_imgIf you have seen older advertisements for the dark Irish beer called Guinness, you may have seen the slogan “Guinness is good for you!” But is this really true, or was it just marketing? Surprisingly, it might actually be a bit of both. Since the slogan first appeared in the 1920s, Guinness has been touted as one of the “better” beers to drink. The initial saying “It’s a good day for a Guinness” began through word of mouth. It was not until 1928 when the first advertisements came out.The official color of “The Black Stuff” is ruby red. The slight tint can be seen if you hold your glass of Guinness up to the light.As part of the marketing research, beer drinkers were asked why they chose Guinness over another drink. The vast majority (9 out of 10) said that it was because Guinness was good for them, and made them feel good. According to Guinness ambassador Domhnall Marnell, “We already had this reputation in the bars before we uttered a word about the beer.” The ads that included “Guinness is good for you” and “Guinness for Strength” were used until the 1940s.Guinness used to be recomended by the family doctor to pregnant or nursing women, but you’d actually need to drink three pints of Guinness to provide the same amount of iron as a single egg yolk.It turns out that the iconic black and white stout actually has high levels of antioxidants, which can help reduce blood clots and the risk of heart attack, according to a study done at the University of Wisconsin. Beer overall has even been shown to have some health benefits, particularly with regard to getting a better sleep, promoting relaxation, and reducing one’s risk of stroke, but in moderation, of course.Up until November 2009, blood donors in Ireland were offered a free pint of Guinness.University of California brewing sciences professor Charlie Bamforth has stated that many beers not only contain high amounts of antioxidants, but also other healthy elements, such as B vitamins, silicon, which helps prevent osteoporosis, and probiotics, to keep your gut in good form.Guinness has also been found to contain folate, which our bodies require to make DNA and other genetic material. Stouts like Guinness contain, on average, around 3.2% of our daily allowance of folate. Professor Bamworth has also found that, since it is made from a lot of unmalted barley, Guinness has one of the highest levels of fiber among other beers.Wooden barrels in Guinness storehouse. Photo by Sebb CC BY-SA 3.0Guinness is also high in iron, containing 0.3mg of iron per beer, or roughly 3 percent of an adult’s daily-recommended dose (although not nearly as much as things like spinach). Because iron is an important component of a substance in red blood cells called hemoglobin, Guinness was, at one point, given to postoperative patients, pregnant women, and women who had just given birth, as it was also believed to increase a new mother’s milk supply.The St. James’s Gate entrance to the Guinness brewery.Some studies have indicated that beer can increase the production of prolactin, which is a hormone required for milk production. However, other studies have shown the exact opposite, and Marnell, the Guinness ambassador, does not recommend that anyone who is pregnant or nursing consume any of their products.Arthur Guinness, founder of the Guinness brewery business.Until 2009 in Ireland, a glass of Guinness was given to volunteers after donating blood, along with the choice of crackers or cookies. The iron in Guinness was thought as a good replacement for the loss of blood. However, the program was scrapped after the legal blood alcohol limit was lowered. That, and getting in the car after giving blood and then downing a pint was not necessarily a good message to send.Gate to the Guinness Brewery in the St. James Gate Area, Dublin.It is commonly believed that Guinness, with its rich-looking, creamy foam, is a high-calorie beverage. However, compared to other beers, it actually has fewer calories. Whereas a 12-oz serving of Heineken has 142 calories, a draft serving of the same size of Guinness has only 125.One other benefit of Guinness over other beers: it is lower in alcohol. Many beers on the market contain around 5% ABV (alcohol by volume), whereas Guinness has only 4.2%.Read another story from us: Guinness Brewery Signed a Lease for 9,000 YearsNonetheless, Guinness is still beer. And Marnell recognizes that, despite its reported health benefits: “If anyone is under the impression that there are health benefits to drinking Guinness, then, unfortunately, I’m the bearer of bad news. Guinness is not going to build muscle or cure you of influenza.”last_img read more
