Touchable Hologram Becomes Reality w Video

first_img Explore further Called the Airborne Ultrasound Tactile Display, the hologram projector uses an ultrasound phenomenon called acoustic radiation pressure to create a pressure sensation on a user’s hands, which are tracked with two Nintendo Wiimotes. As the researchers explain, the method doesn’t use any direct contact and so doesn’t dilute the quality of the hologram. The researchers, led by Hiroyuki Shinoda, currently have the technology on display at SIGGRAPH 2009 in New Orleans. This document is subject to copyright.

Researchers restore light sensitivity to retina using polymerbased optoelectronic interface

first_img Citation: Researchers restore light sensitivity to retina using polymer-based optoelectronic interface (2013, March 18) retrieved 18 August 2019 from https://phys.org/news/2013-03-sensitivity-retina-polymer-based-optoelectronic-interface.html The photoreceptor layer is replaced in the degenerate retina by the organic polymer. Credit: doi:10.1038/nphoton.2013.34 Explore further Journal information: Nature Photonics Zebrafish may hold the answer to repairing damaged retinas and returning eyesight to people This new research by the group follows up on research the team conducted two years ago, where they found that they could grow neurons on top of photovoltaic polymers. In this new effort, they placed the polymer poly(3-hexylthiophene) on a small sheet of glass then followed that up by placing a damaged retina extracted from a rat on top of it. Using the same techniques they’d discovered in their earlier work, they coaxed the cells into incorporating themselves with the polymer. Once that occurred, they shined a light on the result and found that neural activity occurred that was very similar to what happens with retinas that are not damaged.The polymer used in the experiment is one of a class that is able to convert light into electricity without the need for any other power source. Such materials, the researchers believe, make them ideal candidates for use as a possible means of correcting vision problems in people with retina damage due to diseases such as macular degeneration or retinitis pigmentosa. In these cases, the rods and cones—photoreceptor cells—that make up the retina are damaged or destroyed slowly robbing their victim of sight. The idea with the new research is to see if photovoltaic polymers can be used to replace the damaged nerves, and thus restore vision.In their experiments the researchers found the retina/polymer combination responded to what they describe as average daylight brightness levels indicting it might prove useful as a means of treating certain types of blindness. They caution however that they also observed that the combined material did not respond to the full range of brightness levels as seen by a healthy eye, though they suggest they believe more research will produce better results. The team next plans to implant their polymer optoelectronic interface into blind rats to see if it can restore vision and if so, how well.center_img (Phys.org) —A team of researchers in Italy has successfully demonstrated a means for restoring light sensitivity to a damaged rat retina by incorporating an inorganic polymer with nerve cells. In their paper published in the journal Nature Photonics, the team describes how they placed a damaged rat retina atop a glass substrate covered with a light sensitive polymer and then found that shining a light on the mix resulted in neural activity similar to that which occurs with a healthy retina. © 2013 Phys.org More information: A polymer optoelectronic interface restores light sensitivity in blind rat retinas, Nature Photonics (2013) doi:10.1038/nphoton.2013.34AbstractInterfacing organic electronics with biological substrates offers new possibilities for biotechnology by taking advantage of the beneficial properties exhibited by organic conducting polymers. These polymers have been used for cellular interfaces in several applications, including cellular scaffolds, neural probes, biosensors and actuators for drug release. Recently, an organic photovoltaic blend has been used for neuronal stimulation via a photo-excitation process. Here, we document the use of a single-component organic film of poly(3-hexylthiophene) (P3HT) to trigger neuronal firing upon illumination. Moreover, we demonstrate that this bio–organic interface restores light sensitivity in explants of rat retinas with light-induced photoreceptor degeneration. These findings suggest that all-organic devices may play an important future role in subretinal prosthetic implants. This document is subject to copyright.

Semiconductor shish kabob nanostructures combine properties from different dimensions

first_img The scientists, Chun Li, et al., at North Carolina University in Raleigh, North Carolina; and Oak Ridge National Laboratory in Oak Ridge, Tennessee, have published a paper on the nanosheet-nanowire heterostructures in a recent issue of Nano Letters.So far, most research on growing nanoscale heterostructures has focused on combining materials that have the same dimensions. Studies that involve combining materials with different dimensions have remained limited because it is much more difficult to integrate these materials into a single structure due to their different growth mechanisms. However, as the researchers here explain, integrating materials with different dimensions is attractive because it can combine the advantages of both materials while mitigating the disadvantages. As a result, such heterostructures may enable novel functions that cannot be obtained from each of the components separately. (Phys.org) —By growing 2D nanosheets along the surface of a 1D nanowire, scientists have synthesized a new 3D nanoscale heterostructure that they call—for appropriate reasons—”shish kabobs.” Due to the integration of the two dimensionalities, the new structures could have a wide variety of applications, such as for solar energy conversion, energy storage, and photonics.

Journal information: Nano Letters More information: Chun Li, et al. “Epitaxial Nanosheet-Nanowire Heterostructures.” Nano Letters. DOI: 10.1021/nl303876a To synthesize the new nanosheet-nanowire structures in this study, the researchers used a two-step approach, first growing the nanowires and then growing the nanosheets at certain sites on the nanowires. They used germanium sulfide as the material for both components, but predict that the same approach will apply to other similar materials. In order to yield nanowire-nanosheet heterostructures, the researchers exposed the grown nanowires to air for a few minutes to a few days prior to the nanosheet growth step. The air exposure likely causes mild oxidation on the surface of the nanowires, which changes its surface properties. The researchers think that these surface imperfections may facilitate the nucleation of the nanosheets better than a perfect surface can.After the nanowires were exposed to air, the researchers could successfully grow nanosheets on the nanowire surface along the radial direction, so that they were arranged like pieces of chicken and peppers on a skewer. Besides their appeal due to this unusual architecture, the nanowire-nanosheet heterostructures also have an appealing combination of characteristics, notably a large surface area due to the 2D nanosheets and efficient charge transport due to the 1D nanowire. For these reasons, the new nanostructures could have applications in photovoltaics, supercapacitors, lithium-ion batteries, 3D optoelectronics, and chemical sensing.last_img read more

Left strike proves damp squib

first_imgKolkata: The six-hour bandh, called by the Left Front, failed to evoke any response in the state with people rejecting the “strike culture” altogether venturing out for their offices and respective destinations on Friday.It may be recalled that Chief Minister Mamata Banerjee had criticised the strike from 6 am to 12 noon saying that it was nothing but a gimmick. Before leaving the state Secretariat on Thursday, the Chief Minister said they should call a bandh at midnight to make it successful. Also Read – Heavy rain hits traffic, flightsStating that the people of Bengal have rejected the call for the bandh, Partha Chatterjee, secretary general of the Trinamool Congress, said the Left Front has called the strike for political mileage and people have realised that there is no need to respond to such a call which is politically motivated. “Those who are trying to ensure damage to the state have been defeated by the masses,” said Chatterjee adding that the people have once again stood by the development of the state by rejecting the call for bandh. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedAfter the change of guard in 2011, the Mamata Banerjee government has brought an end to the strike culture that had earned a negative image to the state before her government came to power. The state government had taken all the necessary steps to ensure that people do not face any inconvenience to reach their workplaces whenever bandh was called in the past six-and-half-years. It has helped to revive the work culture in the state and with similar arrangements on Friday as well, people did not even realise that there was a call for bandh for six hours till 12 noon on Friday. The state Transport department pressed additional buses into service to ensure that commuters do not face any problem. All modes of transport were available since morning similar to that of other working days.People have not noticed any difference on Friday morning with all the shops remaining open like normal days and people could reach their offices without facing any inconvenience and all marketplaces were also operational. Similarly, school and college goers too did not face any trouble.A resident of North Kolkata, Manoj Jha, who was found taking his daughter to school, said he even didn’t know that a strike has been called and he would also go to his office after dropping his daughter to school.The turnout at all the state government offices was overwhelming. Like all other days, employees started turning up before 10 am and there were the usual queues to take the elevator at Nabanna. A similar overwhelming response of employees was also found in offices of the state government in the districts as well. Sources added that there was cent percent attendance in the Personnel and Administrative Reforms Department. The picture was same in the state IT hub at Salt Lake where techies joined their work with equal enthusiasm. According to a senior official of an IT company, people in Salt Lake Sector V were not even aware that there was a bandh. Many delegates from other states also visited some of the offices on Friday and they were happy to know that there was no effect of the bandh in the state’s IT sector, the official added.last_img read more

Going beyond just pottery

first_imgWhen a Professor decides to hang up her boots and probe hidden embers of firing and glazes and clay constructions – it becomes more than a mere pilgrim’s journey. Manjari Sharma’s affair with stoneware began more than 15 years ago when exploring clay meant going beyond pots and bowls and platters – exploring clay meant an embodiment of the gestural spontaneity and visual momentum of abstraction as well as gauging degrees of expressionism along with the dramatic Shakespearean – like acceptance of imperfections that characterizes the creation of sculptural pottery in all its manifestations. Also Read – Add new books to your shelfManjari works with a personal structural vocabulary which she pours overthrown shapes including cylinders, bowls, plates, clay slabs, and whatever forms her hand or mallet could pierce, press, pinch or paddle. Pottery is not only bowls and pots and platters, pottery is a journey that enfolds and explores and experiments with forms and glazes and textures and expression. Manjari moves a step ahead with human expressions that are full of drama and deep intensity. Her lamps with quirky lips are delightful, her bowls with human hands are truly sculptural, her jars with lids that have fingers are a statement in the power of human emotions. Also Read – Over 2 hours screen time daily will make your kids impulsive”A very noticeable outcome of my journey within was a loss of fear and hence the ability to play more. In the celebration of the “human experience”, I found greater acceptability of the good with the bad or the pretty with the ugly. I realized that everything is contextual. There are no absolute truths. In fact, I feel that perfection and beauty are fairly violent concepts they are so non-inclusive,” says sculptor Manjari Sharma. Curator Uma Nair who has followed her works for 20 years says,”Manjari doesn’t merely throw pots, she builds and fashions them. Indeed, she uses a potter’s wheel on which to spin the initial clay forms; but after that first rudimentary step the traditional method of wheel-thrown pottery is dramatically overturned.” The show which opened on April 16, will run till April 23 at Lalit Kala Akademi, Rabindra Bhavan.last_img read more

We have sacked Khan from our party and now BJP has given him a platform.” He said the rally on January 19 at Brigade parade ground will be a historic one and all the national leaders will come to strengthen the hand of Mamata Banerjee, who had first spoken about the Federal Front. He urged the people to attend the rally on January 19. “She will give us the roadmap which we will follow in the Lok Sabha election. It is Mamata Banerjee’s dream to win 42 out of 42 seats in Lok Sabha and we should work hard to fulfill it,” he added. He cautioned people against BJP’s divisive politics. “BJP wants to divide the society and we should not fall into their trap. We believe that Hinduism is humanism and we follow the path of Swami Vivekananda,” Banerjee said.last_img read more

Money management for millenials

first_imgMillennials as a group believes in living for the present. They are clued in about social media and online trends, are tech savvy and comfortable using mobile apps for almost everything, whether it be ordering food or a cab ride to online banking and investment. With the availability of EMIs and easy financing, cost is no longer an issue when making a purchase. Experts list seven tips for millennials to ensure they maintain the standard of living they are used to:Track spends and bill payments smartly, set a budgetUsing apps that track spends makes this very simple. Not only are spends displayed and managed automatically, the app also shows upcoming bill reminders for credit cards and other utilities. Setting a budget ensures there is no overspending.Save at least 10 per cent of salary every monthLiving on the edge, or from one salary to the next, is not a good idea, and each month, it is prudent to set aside at least 10 per cent of the salary towards savings as soon as it is credited. This can be an SIP in an equity fund or debt fund, or even a Fixed Deposit, depending on risk profile.Explore different investment classesWhile most families in India have grown up with the belief that a Fixed Deposit is the only way to invest, there are many other options available, right from equity and debt mutual funds and stock markets to gold, real estate, art and so on. Appetite for risk should always be factored in before choosing any of these options.Get a health insurance cover”Live for the moment” seems glamorous, but an accident or medical emergency can lead to a financial disaster and impact lifestyle. When young, there are lesser chances of pre-existing diseases and so premium is much lower and this should be utilised to get a Rs 5 lakh or even a Rs 10 lakh cover.Get tax planning in orderAvoid waiting till February or March, by planning tax saving investments from April itself when the financial year begins. Once salary details are known, check tax liability and how much tax can be saved by exploring all avenues available. If planning to invest in Public Provident Fund (PPF) or tax saving mutual funds, start contribution early and monthly. For mutual funds, set up a Systematic Investment Plan (SIP), so the money is invested each month and not a large outflow later.Keep an emergency fundLoss of job, an accident or illness etc cause a strain on finances, even with health insurance. Once monthly spend pattern is known, this emergency fund should take care of living expenses and upcoming commitments, and be easily accessible.Stick to the planAll plans can go waste if they exist only on paper; so self discipline is extremely important to ensure all spends are tracked, and investments are completed as planned.last_img read more

BJP Modi speaking about religion which is not Hinduism

first_imgIslampur: Trinamool Congress supremo Mamata Banerjee said Hindusthan will be set up through the Lok Sabha election and not Modisthan or BJPsthan. She was addressing a rally here on Tuesday afternoon.Banerjee said Modi and BJP are talking about a religion which is not Hinduism. “Hinduism talks about tolerance and acceptance and they are talking about hatred. In the name of preservation of cows, many people have been lynched. They are spreading hatred everywhere. This Hindusthan is Modisthan and BJPsthan. We do not want this. We want a Hindusthan where people will live peacefully and there will be communal harmony and peace,” she said, adding: “BJP is inciting one religion against the other and in the name of religion, they have unleashed a reign of terror. We want to come out of this,” she maintained. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataReferring to Modi and BJP national president Amit Shah as Duryodhan and Dushshashan, she said: “The duo has come to destroy the social fabric in our country. Never in the past have I seen so much hatred and disrespect for others. This is not Indian tradition. Indians are respected for their tolerant views.” Banerjee said the SC, ST, minorities and dalits will vote against Modi. “The SCs, STs and Dalits have been tortured in different areas. In Jharkhand, they have been thrown out from their land. In Uttar Pradesh and Assam, Muslims have been tortured by BJP workers and the state governments do not take any action against them,” she said. Also Read – Lightning kills 8, injures 16 in state”They should first see the law and order situation in their own states before commenting on the situation in Bengal. They come to Bengal to disturb the areas. They incite the people living in the hills against those living in the plains to win elections,” Banerjee added. The Trinamool supremo said demonetisation has affected poor people and farmers badly. “Over two crore people have lost their jobs and 12,000 farmers have committed suicide after failing to pay loans. People have stood in long queues to withdraw their own money from the banks. Modi had said note ban will stop circulation of money among terrorists, but in reality terrorist attacks have been the highest during Modi’s time,” she said. Banerjee questioned why no action was taken to save the lives of the jawans in Pulwama despite prior information, adding: “It’s a matter of shame for BJP that its leaders are talking about the achievements of the Army in its election speeches.” “Just as Ma Durga had killed Asura, the women of the country will vote against BJP to oust Modi and set up a secular pro-development government,” she said.last_img read more

Vloggers can promote unhealthy food intake in kids

first_imgUnhealthy food endorsements by video bloggers, or vloggers, on Instagram increase children’s intake of such foods, a study suggests. Children are increasingly exposed to marketing through digital avenues, such as on social media, and the impact of marketing by vloggers on these outcomes has, until now, not been known, said researchers from the University of Liverpool in the UK. The study, published in the journal Pediatrics, examined the effect of social media marketing of snack foods (healthy and unhealthy), via vloggers’ Instagram pages, on children’s snack intake. Also Read – Add new books to your shelf”These findings suggest that the marketing of unhealthy foods, via vloggers’ Instagram pages, increases children’s immediate energy intake,” said Anna Coates, PhD student at the University of Liverpool. “The results are supported by celebrity endorsement data, which show unhealthy food endorsements increase children’s unhealthy food intake, but healthy food endorsements have little or no effect on healthy food intake.” During the study 176 children, aged between 9 and 11 years, were randomly split into three equal groups and were shown artificially created, but realistic, Instagram pages of popular vloggers (each has millions of followers). Also Read – Over 2 hours screen time daily will make your kids impulsiveOne group was shown images of the vlogger with unhealthy snacks, the second group was shown images of the vlogger with healthy snacks and the third group was shown images of the vlogger with non-food products. The participants’ subsequent intake of snacks were measured. Children in the group that viewed the unhealthy snack images consumed 32 per cent more kilo calories (kcals) from unhealthy snacks specifically and 26 per cent more kcals in total (from healthy and unhealthy snacks) compared with children who saw the non-food images. There was no significant difference in total kcal intake, or healthy snack kcal intake, between children who saw the Instagram profile with healthy images and those who saw the non-food images. “Young people trust vloggers more than celebrities,” Coates said.last_img read more

Trying for infrastructural development so that enrollment rises Partha

first_imgKolkata: State Education minister Partha Chatterjee on Monday said his department is planning for amalgamation and at the same time developing infrastructure at the primary schools to have a proper balance of teachers and students. There are schools in which students are less in comparison to the teachers and vice versa.”The total number of primary schools in the state is 50,108 presently out of which 2,048 schools have students where the number is less than 20. We are trying for infrastructural development so that the enrollment goes up and at the same time introducing English-medium schools in the state. We have already identified 100 schools for English-medium among which 65 schools have already been upgraded. We have set a target of having 1,000 English-medium schools,” Chatterjee said in response to a query from TMC MLA Bankim Hazra at the state Assembly on Monday. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataChatterjee, during the course of supplementary questions, provided data before the House of the number of schools where students’ strength is less than 20. The number of upper primary schools in this regard is 554, secondary schools are 76 and higher secondary schools are 14. “We have not closed down any of these schools and are trying all means to attract students. The department is providing laptops with projectors in a number of schools to make the learning experience interesting. Providing mid-day meals should not be the only means to attract students and there should be something for the students which involve some sort of brain work on their part,” he added. Also Read – Lightning kills 8, injures 16 in stateChatterjee further pointed out that the Left Front government’s decision in 1982 to do away with English in the primary level had resulted in a sharp decline of students in government schools as they have opted for private English-medium schools which teach the subject right from the pre-primary level. The minister also expressed his concern over the mushrooming of CBSE and ICSE and Montessori schools over which the state primary Board has no control. “The permission to set up these schools are given by the Central government and we only provide the No Objection Certificate (NOC). We have already spoken to the Centre and highlighted the problem. Until we are empowered by the Centre to have our say in granting permission about setting up the schools, we are helpless,” he claimed.last_img read more

These Mysterious Cave Drawings Used Modern Techniques of Perspective and Movement

first_imgIf you visit Chauvet Cave in the Ardèche region of France, you will be witness to an art site that dates back over 30,000 years. According to the website Experience Ardèche, the caves were discovered by accident in 1994. Local men were caving when they came across what has now been identified as one of the oldest pre-historic art caves in the world. Christian Hillaire, Eliette Brunel-Deschamps, and Jean-Marie Chauvet stumbled upon the cave one day. Once inside, they discovered the over 1,000 unique cave paintings. Experience Ardèche tells us that the drawings were of animals, such as horses, lions, and bears. More interesting, they say, is that the paintings used modern techniques such as perspective and movement.Chauvet cave. Photo by Nachosan CC BY-SA 3.0In her article from 2007, Emma Groeneveld explains that researchers have confirmed the caves were inhabited on at least two occasions by humans. The first period was between 33,500 and 37,500 years ago. Humans again occupied the cave some 27,000 to 32,000 years ago. Scientists have determined that after that, the cave remained unopened for at least the past 21,000 years.According to Groeneveld, the artists made paint from charcoal or manganese dioxide along with red pigment. They painted on the cave walls by firelight and this likely enhanced the use of shadowing and technique. Artists in that time would paint using rocks, brushes or even their hands.Handprint.

The front room contains painting mostly in red paint while the back room primarily consists of darker painting, in black or charcoal.Engraving of an owl from the Chauvet cave.There are complete drawings of animals, including an entire pride of lions. The technique is almost three-dimensional, making it appear as if the animals are perched to leap off the walls at any moment.In the very back of the cave, Groeneveld reveals that intricate drawings were discovered. There was a scene of a pride of lions, tensely posed, staring at a pack of bison. You can tell that the artist was drawing a hunting scene. Strangely, there are paintings of more than just animals in this back section.Cave hyena (Crocuta crocuta spelaea) painting found in the Chauvet cave and made public on January 17, 1995, by the Minister of Culture Jacques Toubon.There are pictures of something called the “Sorcerer.” Groeneveld describes it as the lower half of a woman’s body with the top half of a bison, with a horned head. There is no concrete explanation for what this represents.Amazing Mountain Top MonasteriesHumans were in these caves as they expressed their visions on the cave walls. Evidence of both human and animal life includes, according to ThoughtCo, animal bones, iron spearheads and even a human footprint. There is, of course, a debate over just how long-ago humans occupied the caves.Horse engraved by finger into the soft wall. Pont d’Arc cave. Photo by Claude Valette CC BY-SA 4.0Some researchers have used radiocarbon measurements to try to calculate the age of the caves. They can test radiocarbon on the animal and human bones as well as on the paint found on the walls. Some scientists argue that the radiocarbon existed in the caves before the paintings.Hands (including a trace of a curved little finger: this character is found in various places in the cave), enigmatic signs, red and yellow drawings. Pont d’Arc cave (copy of the Chauvet Cave). Photo by Claude Valette CC BY-SA 4.0The radiocarbon — a molecule that helps in determining the age of organic material — could have attached themselves to fossils and materials, thus skewing the actual age of the items.Read another story from us: “Hobbit” Island: Where Humans and Animals ShrinkWhile all of this testing has been taking place, mostly for over 20 years, the cave has been sealed off to the public.  However, in 2014 the cave received UNESCO heritage status. People were excited to see the cave and its paintings. Experience Ardèche tells us that to let people get an idea of what had been discovered, they created a reconstitution of the Chauvet Cave to preserve the original and opened it up to the public in April of 2015.last_img read more

Honest Ale Abraham Lincolns Early Job as a Bartender

first_imgBecoming Leader of the Free World cements a man’s position in the history books, though it’s easy to forget these individuals had a life before entering the White House. Take Abraham Lincoln for example. Arguably the most famous President, he overcame a tough upbringing to inspire the nation via the Gettysburg address and make a humanitarian impact on the Civil War.Abraham LincolnBefore that he’d worked a variety of jobs, including what some would describe as a “barman” in New Salem, Illinois.The mind races at the possibility of Honest Abe dispensing drinks and listening to customer’s worries. In fact, it sounds like a solid premise for a sitcom.New Salem, Illinois, USA. Photo by Amos Oliver Doyle CC BY-SA 3.0The reality is a little different. An article on the website of the New Salem Lincoln League is keen to set the record straight, asking “was Lincoln ever a bartender? Nope, not really. At least as we understand the term “bartender” today. And there was never a saloon… called Berry and Lincoln.”Berry/Lincoln Store and Post Office at New Salem, Illinois, USA. Photo by Amos Oliver Doyle CC BY-SA 3.0So what did the future President do in New Salem, and who was Berry? Lincoln arrived in Illinois aged 21, accompanying his family. He’d had quite a journey through life before that.The young Abraham was educated against a backdrop of upheaval following a land dispute. His father moved the clan around and at one point Abe walked for miles through the Indiana wilderness to obtain books.Berry/Lincoln Store at New Salem, Illinois. Village of Abraham Lincoln. Photo by Amos Oliver Doyle CC BY-SA 3.0New Salem was the moment he chose to fly the nest and establish himself. The Enchanted Manor website writes that he “spent six years working several different jobs in the village.He split rails and worked on a riverboat, was a store clerk and general store owner, served as the postmaster and deputy surveyor and enlisted as a soldier in the Black Hawk War… before being elected to the Illinois General Assembly in 1834.”Abraham Lincoln, 1861.It was his time as owner of a general store that led to his association with alcohol. He went into partnership with friend William F. Berry and they started up the Berry and Lincoln store.According to the Find A Grave entry for Berry, quoting pages from New Salem History, the pair “founded two Berry-Lincoln stores; and for a short time, the two men were thriving merchants.”Old dug water well at New Salem, Illinois. Photo by Amos Oliver Doyle CC BY-SA 4.0While they sold booze, it was far from a watering hole. The Chicagoist site states that “Stores could sell alcohol in quantities greater than a pint for off-premises consumption, but it was illegal to sell single drinks to consume at the store without a license.In March 1833, Berry and Lincoln were issued a tavern, or liquor, license, which cost them $7 and was taken out in Berry’s name. Stores that sold liquor to consume on the premises were called groceries.A tipple was merely one of the things you could purchase at Lincoln’s business. This was a more tempting proposition than most, but not enough to qualify him as a barkeep. Brandy, gin, rum and whiskey were passed over the counter to Abe’s patrons.Berry and Lincoln store, Stock bought of Greene Jan. 1833, Lincoln’s New Salem, Illinois.It sounds simple enough, yet the enterprise didn’t last long. Neither seemed particularly suited to running a shop. Lincoln’s writings suggest it was something he fell into, and some sources claim Berry had a habit of quenching his thirst on the job.Berry passed away from malaria fever in 1835, by which time Lincoln had moved on to become Postmaster of New Salem. He took on the store’s debts, which took him years to pay off, according to The Story of Young Abraham Lincoln by Wayne Whipple.New Salem History writes that “William Franklin, Reverend Berry’s oldest son, was a very astute businessman, and he did not leave a large debt for Lincoln to pay off.”Lincoln in February 1865, about two months before his death.“He had some wealth and actually paid some of Lincoln’s debts.” It also details Lincoln’s close relationship with the Berry family.When Lincoln rose up the ranks in political circles he distanced himself from his former role as purveyor of spirits. He even went as far as to deny such a thing ever took place, whilst in debate with Democratic Senator Stephen Douglas in 1858.The irony of this position is highlighted by the Chicagoist, who wrote: “Holders of the nation’s highest office have often had a close relationship with booze, as George Washington established the nation’s largest whiskey distillery in 1797 and Thomas Jefferson brewed his own beer.”Read another story from us: Young Abraham Lincoln was a Champion WrestlerLincoln may not have wanted his name tied to liquor. But the Americans he served at his general store were no doubt as grateful as those he ultimately served in his capacity as President of the United States.last_img read more

Heres How to Stop Third Parties From Reading Your Gmail

first_imgSeptember 24, 2018 Children pass notes, and high school students send text messages. But twenty-somethings, eighty-somethings and everyone in between tend to gravitate to email.As we age, our primary method of communication may change, but our expectations of privacy remain relatively constant. But when it comes to email, a letter from Google to lawmakers revealed that those expectations may be moot.The letter, which was first reported by The Wall Street Journal, was sent in advance of the tech giant’s scheduled appearance at a Senate Commerce Committee hearing on Sept. 26. The issue on the docket is safeguards for consumer privacy, and senior executives from Google will appear alongside those of Apple, Amazon, Twitter, AT&T and Charter Communications.The main revelation from the letter? Though Google itself stopped mining users’ emails for ad targeting purposes in 2017, it continues to allow third-party app developers to do so. What’s more, as long as Google okays the privacy policy beforehand, app developers are free to share that data with any number of partners and third parties.A whole host of apps offer useful services that may tempt Gmail users to sign up — tracking purchases to alert you to potential retroactive discounts, helping to manage a flooded inbox, planning flights according to best purchase times. But data such as what you’re buying, where you plan to travel and when you tend to check your email is valuable to advertisers who aim to target you more accurately, and app developers are often well-compensated for sharing it with partners.Perhaps the most unsettling practice that’s come to light here: It’s not just algorithms that can scan your inbox. At some app companies, employees themselves have been known to read users’ emails to help improve the software.There is a caveat: Google has to give privacy policies the green light beforehand, which usually involves making sure the document is “easily accessible to users to review before deciding whether to grant access,” wrote Susan Molinari, a vice president at Google, in the letter. Be that as it may, that’s likely not enough for the vast majority of Americans: A 2015 Pew Research Center survey found that 74 percent said it’s “very important” to them to be in control of who has access to their information. And since Gmail claims the lion’s share of today’s email market, it’s important to take a close look at exactly what Google is doing to protect users’ personal data.Ahead of the Senate hearing on Sept. 26, here’s a step-by-step guide for how to see exactly which companies can access your email — or share it with third parties.1. Click on your Gmail account photo on the upper right-hand corner of your email inbox.2. Click the blue button labeled “Google Account.”3. Inside the “Sign-in & Security” box on the left, choose “Apps with account access.”4. You should see a list of “Apps with access to your account” — click “Manage Apps” for more information.5. Click on each of the apps in the list to see what they have permission to view and do (for example: “Read, send, delete and manage your email”).6. Revoke access for the apps of your choice. (Remember, if a service is free, you — and your data — are often the product.) 3 min read Register Now »center_img Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Growing a business sometimes requires thinking outside the box.last_img read more
