first_img “It is projected that the next generation of computer chips will produce localized heat flux over 10 MW/m2, with the total power exceeding 300 W. No existing low-cost cooling device can effectively manage the heat produced at this level,” asserts the Letter. The study will accelerate the development of next generation of cooling devices that incorporate nanofluids for ultrahigh-heat-flux electronic systems.The results of the experiment show that when an oscillating heat pipe (OHP) is charged with a nanofluid, the ability of the OHP to transport heat increases. As this experiment illustrates, finding more efficient cooling for the next generation of computer chips, microchips, and electronic devices is under way. As society desires its gadgets to shrink ever smaller resulting in high power density, teams that work to develop the technology will find themselves in high demand. “There are lots of applications that come from this experiment,” says Ma. “We really need to develop this further.”While neither the study of nanofluids nor the study of OHPs is anything new, combining the unique features of each is an innovative approach. “Here we use a nanofluid and an oscillating motion. The oscillating motions make the nanoparticles suspend in the base liquid. This is unique.” says Ma. “No cooling device has been made using a nanofluid-charged OHP, but the development of such a device is now a few steps closer, and with it the enabling ability to take our technology even farther than it has already gone.”The unique characteristics of both nanofluids and OHPs contribute to the fitness of such devices for cooling functions. Traditional liquids have much lower thermal conductivities than nanofluids. Additionally, nanofluids have strong temerpature-dependent thermal conductivity, as well as showing a non-linear relationship between thermal conductivity and concentration. These particular features, which belong to fluids that exist on the nanoscale, make them high performance conductors with an increase in critical heat flux.Oscillating heat pipes have their own set of unique features. First of all, an OHP is known as an “active” cooling device. It takes intense heat from a high-power device and turns it into kinetic energy of fluids. Additionally, with an OHP, liquid flow and vapor flow move in the same direction, so neither phase interferes with the other. Because the flow in an OHP is one that oscillates from a thermally driven flow, there are some blank surfaces that appear along the pipe. This allows for enhanced evaporating and condensing heat transfer. So, while the OHP already has good heat transporting ability, the addition of a nanofluid can enhance the ability of the OHP significantly. In this particular experiment, the nanofluids used contained diamond nanoparticles. The diamond particles were introduced into high performance liquid chromatography (HPLC) water. HPLC water is water that is specially purified and that has a low organic carbon content. Even though diamond particles might settle in liquid without motion, the movement of an OHP keeps those particles from settling, allowing them to remain suspended.While the experiment shows that the nanofluid-charged OHP has increased efficiency, the ‘why’ behind the fact has yet to be discovered. “We know some of the reasons,” explains Ma, “but not all. We are trying to find the reason for the higher efficiency transfer. We’re not entirely sure why the efficiency increases so much after we add the nanoparticles.”The results from this experiment are encouraging to those who are studying ways to effectively reduce the size of electronics while increasing their output, as it points to a technique that can used for effective cooling. As the letter puts it: “This study on a nanofluid OHP will advance the state of the art in nanofluid applications…”By Miranda Marquit, Copyright 2006 PhysOrg.com “This is the next generation of cooling devices,” Dr. Hongbin Ma tells PhysOrg.com. With a group of students at the University of Missouri-Columbia, and colleagues at Argonne National Laboratory and Intel Corporation, Ma presents the findings of a unique cooling device that makes use of an Oscillating Heat Pipe (OHP) and nanofluids. The findings, published online at Applied Physics Letters on April 5th, present a breakthrough that will provide a way for cooling technology to keep pace with developments in electronic technology.

first_imgMost computers today store memory electronically, by maintaining a certain voltage. In contrast, a new kind of memory that stores data thermally, by maintaining temperature, is being investigated by researchers Lei Wang of the National University of Singapore and the Renmin University of China, and Baowen Li of the National University of Singapore and the NUS Graduate School for Integrative Sciences and Engineering.

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.center_img In recent years, thermal research has improved scientists’ understanding of heat conduction on a molecular level. Scientists have created theoretical models of some thermal devices, including a thermal transistor and logic gate, both by Wang and Li in 2006 and 2007, respectively. This kind of work has opened the doors to the new subject of “phononics” – the science and engineering of processing information with heat. In the current study, Wang and Li take the field of phononics one step further and show the feasibility of a thermal memory that can store data with heat. The scientists predict that such a heat memory could be experimentally realized in the foreseeable future with rapidly advancing nanotechnology. Their work is published in a recent issue of Physical Review Letters.As Wang and Li explain, any thermally insulated system might be a candidate for thermal memory since it maintains its temperature (data) for a long time. Still, any system will face the challenge of unavoidable perturbation when the temperature is measured (when the data is read). Due to energy exchange between the thermometer and the system, the system won’t be able to naturally recover its original temperature after the data reading. To solve this problem, the researchers suggest using a thermal circuit capable of producing two steady states, which is connected to a power supply from an external heat bath.Wang and Li’s thermal memory consists of a single particle sandwiched between two lattice segments, each consisting of about 50 atoms. These left and right segments are connected to heat baths at different fixed temperatures, and the central particle is connected to a control heat bath that can be set to “on” or “off.” The particle’s chosen state can remain unchanged for a long time even after the heat bath is removed. The particle and the segments are also weakly coupled together by harmonic springs. This memory system, the researchers explain, can perform a complete write-read process. The “writer” is made of a lattice of about 10 particles, connected to the central particle by a linear spring. The other end of the writer is connected to a heat bath. Depending on the supply from the heat bath, the writer can either cool the particle to the off state or heat it to the on state. To read the data, a thermometer (made of the same lattice as the writer) is connected to the central particle. Unlike the writer, the reader is not connected to a heat bath, but is set to a temperature between the on and off states. If the particle is in the on (hot) state, the reader will heat up; if the particle is off (cool), the reader cools down. Of course, the particle’s temperature will also change when exposed to the medium-temperature reader. But the heat baths connected to the left and right segments will either absorb the particle’s excess heat or warm the particle, so that the particle recovers its original temperature (and state) in either case.The researchers calculated that, when the writer is removed, the system can maintain its state for a relatively long time, although an ideal thermal memory is impossible due to thermal fluctuations. However, by refreshing the data (similar to how voltage data is regularly refreshed in dynamic random access memory [DRAM]), thermal memory can achieve a lifetime long enough for practical applications. The scientists also noted that the lifetime can be extended further by combining identical memories together.By theoretically demonstrating the possibility of a thermal memory that is self-recoverable after being read by a thermometer, Wang and Li hope that computers will one day reap the benefits of thermal technology.More information: Wang, Lei and Li, Baowen. “Thermal Memory: A Storage of Phononic Information.” Physical Review Letters 101, 267203 (2008).© 2009 PhysOrg.com Controlling heat and particle currents in nanodevices by quantum observationlast_img read more

first_img Explore further The process involves mixing superparamagnetic manganese ferrite colloidal nanoparticles with individual molecules or monomers that make up the cellulose fibers in paper products or other nonwoven materials and getting them to connect, forming polymers, by submersion in a liquid solution. This process causes a thin shell to form around each fiber. The result is a solution that when applied to paper produces a final product that is both waterproof and magnetic. The team says they’ve also found that the amount of nanoparticles used in the process can be varied to adjust the degree of magnetism the paper will have.By adjusting the kinds of nanoparticles used in creating their solution, the team has found that the resultant paper can be made to demonstrate other properties as well. Using silver nanoparticles for example, allows for creating paper that is resistant to bacteria. Similarly, florescent paper can be made using other substances. There also exists the possibility of mixing up the ingredients to create paper that demonstrates several of the properties, or conceivably all of them at once.While the advantages of waterproof paper are obvious, the team notes that making paper magnetic could be useful for security applications such as when making bank notes or even currency. Also, paper that has antibacterial properties could be used in medical applications or food preparations, or perhaps with currency as well seeing as how many studies have shown that paper money carries all manner of bugs that can make people sick. Florescent paper could be used in security applications but also would likely have a lot of other uses such as in making posters that don’t require a black-light to create eerie effects, documents that could be read in the dark, or as a means of encoding data that only appears when the lights are turned out.The team points out that because the paper as a whole is not being coated, the paper produced from the process retains all of its normal properties. Thus, it can still be written or printed on with normal pens and printers. Also, they say, the solution they create can be applied to paper that already exists, allowing users to change the properties of already printed books, magazines, documents or virtually any other paper product.

Using parallax he was able to come up with a very close estimate of just how far the Earth was from Mars, and then the Earth from the sun, which he said should be about 140 million kilometers. That eerily accurate figure came to be used throughout astronomy as a standard for describing distances in the visible solar system. To make it more accurate, the calculation was changed in 1976 to include a tie to the sun’s mass, which for newcomers to the field only made things more difficult to understand. It also didn’t take into account the fact that the sun is gradually shrinking.Subsequent new developments in science and technology have led to much more precise ways to measure the distance between solar objects, which served to make using the old calculation even more obsolete. The only reason it’s lingered as long as it has, astronomers say, is because everyone was used to it and thought changing things might be too disruptive.That line of thinking apparently gave away to common sense at the latest meeting of the IAU, as members voted to make the AU an exact 149,597,870,700 meters, which is the average mean distance between the Earth and sun when viewed from the Earth. This last point is important because the old calculation violated Einstein’s Theory of Relativity in that using it should have given different answers depending on where the measurement was taken, i.e. from different objects in the solar system.Most in the field seem to be relieved to finally have the AU changed to a constant, believing it will help make their work more accurate and because it will, of course, require a lot less explaining to those new to astronomy.

first_img Explore further (Phys.org) —Researchers from the University of Kentucky have identified 14 molecular markers in bedbug genes commonly associated with resistance to pyrethroid, the most popular pesticide used to control them. In their paper published in the journal Scientific Reports, the team describes how they compared genes from pyrethroid resistant bedbugs found in the Los Angeles area, to those from other areas of the country that had not yet developed a resistance, and as a result were able to identify 14 gene markers, that are associated with resistance to the pesticide. Bedbugs have been in the news of late as outbreaks have occurred in cities throughout the world. They are parasites that feed on the blood of their hosts and leave behind itchy rashes. Efforts to eradicate them have become less effective as the pesticide most commonly used to kill them—pyrethroid—has become less lethal in some areas as the bugs develop resistance to it. In this new effort, the research team compared the genes of bedbugs found in the Los Angeles area that were known to have developed a resistance, with bedbug gene samples from 20 populations from other parts of the country that thus far, have not. In so doing, they found 14 markers, which they report, mostly involve the bugs’ outer shell, which serves as a barrier, preventing the toxin from reaching the inner body, allowing it to survive.The markers found by the researchers represent genes responsible for a variety of outer shell properties such as shell thickness, enzyme levels involved in metabolizing pyrethroid, etc. They also found that the markers represented two categories of defense, those responsible for neutralizing the pesticide before it could reach sensitive areas, and those that physically prevented the chemical from gaining entry to the body in the first place. Taken together, the markers represent a formidable line of defense that has evolved with bedbugs that helps them survive in a hostile environment.Because bedbugs are evolving in ways that make them resistant to current pesticides, researchers are looking for other ways to kill them—learning more about the ways they are evolving that help them survive doses of pyrethroid gives researchers a better picture of what is occurring, which will hopefully result in revealing an unknown vulnerability that could be exploited for use in a new kind of pesticide. Journal information: Scientific Reports More information: Bed bugs evolved unique adaptive strategy to resist pyrethroid insecticides, Scientific Reports 3, 1456, doi:10.1038/srep01456AbstractRecent advances in genomic and post-genomic technologies have facilitated a genome-wide analysis of the insecticide resistance-associated genes in insects. Through bed bug, Cimex lectularius transcriptome analysis, we identified 14 molecular markers associated with pyrethroid resistance. Our studies revealed that most of the resistance-associated genes functioning in diverse mechanisms are expressed in the epidermal layer of the integument, which could prevent or slow down the toxin from reaching the target sites on nerve cells, where an additional layer of resistance (kdr) is possible. This strategy evolved in bed bugs is based on their unique morphological, physiological and behavioral characteristics and has not been reported in any other insect species. RNA interference-aided knockdown of resistance associated genes showed the relative contribution of each mechanism towards overall resistance development. Understanding the complexity of adaptive strategies employed by bed bugs will help in designing the most effective and sustainable bed bug control methods.

first_img(Phys.org)—A trio of researchers working in Germany has discovered that male spiders do indeed have nerves in their genitalia, overturning prior research that has suggested otherwise. In their paper published in The Royal Society Biology Letters, Elisabeth Lipke, Jörg Hammel and Peter Michalik describe the various techniques they used to discover nerves in the arachnid palpal organ and their ideas on what purpose they serve. Citation: Nerves found to exist in male spider genitalia (2015, July 8) retrieved 18 August 2019 from https://phys.org/news/2015-07-nerves-male-spider-genitalia.html Explore further More information: First evidence of neurons in the male copulatory organ of a spider (Arachnida, Araneae) The Royal Society Biology Letters, Published 8 July 2015.DOI: 10.1098/rsbl.2015.0465AbstractSpider males have evolved a remarkable way of transferring sperm by using a modified part of their pedipalps, the so-called palpal organ. The palpal organ is ontogenetically derived from tarsal claws; however, no nerves, sensory organs or muscles have been detected in the palpal bulb so far, suggesting that the spider male copulatory organ is numb and sensorily blind. Here, we document the presence of neurons and a nerve inside the male palpal organ of a spider for the first time. Several neurons that are located in the embolus are attached to the surrounding cuticle where stresses and strains lead to a deformation (stretching) of the palpal cuticle on a local scale, suggesting a putative proprioreceptive function. Consequently, the male copulatory organ of this species is not just a numb structure but likely able to directly perceive sensory input during sperm transfer. In addition, we identified two glands in the palpal organ, one of which is located in the embolus (embolus gland). The embolus gland appears to be directly innervated, which could allow for rapid modulation of secretory activity. Thus, we hypothesize that the transferred seminal fluid can be modulated to influence female processes. Cutting a bugs’ penis shorter found to reduce reproduction chances Araneus diadematus. Credit: André Karwath/Wikipedia © 2015 Phys.org For many years scientists have believed that the palpal organ in male spiders—the organ responsible for delivering sperm to the female spider—had no nerves in it. That would mean that the male would not be able to feel anything during intercourse, which some observers have likened to attempting sex with a fingernail in the dark. It appears prior researchers did not look hard enough, however, because the trio working on this new effort report that they have found evidence of nerves in the palpal organ.To make their discovery, the team first cut up several of the organs (from a male Tasmanian cave spider) into extremely thin slices. They then looked at the samples using three different types of microscopes, one of which was a transmission electron microscope—and that allowed them to spot a tiny nerve. More work revealed two clusters of nerves in the bulb. They also spotted two previously unknown glands also in the palpal bulb which appeared to be connected the nerves they found. Using data from the microscopes, the team built a 3D model of the palpal showing where the nerves are in the organ.The researchers suggest that the nerves in the palpal bulb might serve to allow the male spider to feel stress on the organ during copulation, helping to improve placement and thus chances of successful fertilization. It is also possible, they note, that the nerves help with guiding the palpal to the female sex organ. They believe that it is unlikely that such nerves exist only in the species they studied, which means other spiders likely have them too. More research will be needed to find out. The team also plans to study the nerves they found to see if they can determine their true purpose. This document is subject to copyright.

first_imgExposure to adverse events as children – including physical and emotional neglect, violence, and sexual abuse – is strongly associated with adolescent depression and violence perpetrated by young people in poor urban areas around the world, including India, a study has found. Based in multiple countries across five continents, a study, published recently, found that boys are suffering even more than girls. “This is the first global study to investigate how a cluster of traumatic childhood experiences known as ACEs, or adverse childhood experiences, work together to cause specific health issues in early adolescence with terrible, life-long consequences,” said Robert Blum, from the Johns Hopkins Bloomberg School of Public Health in the US. Also Read – Add new books to your shelf”While we found young girls often suffer significantly, contrary to common belief, boys reported even greater exposure to violence and neglect, which makes them more likely to be violent in return,” Blum said. The study catalogued the ACEs suffered by 1,284 adolescents aged 10 to 14 in 14 “low-income urban settings” around the world. It found remarkably common experiences with trauma – and very similar impacts – regardless of where the children lived, which included Vietnam, China, Bolivia, Egypt, India, Kenya, UK and the US. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe report is the first to include an assessment of how adversity impacts young children in multiple low – and middle-income countries, where the vast majority of the 1.8 billion 10- to 24-year-olds worldwide live – about a quarter of the global population. The study found that 46 per cent of young adolescents reported experiencing violence, 38 per cent suffered emotional neglect and 29 per cent experienced physical neglect. However, boys stood out in several categories. For both boys and girls, the more adversity they experienced, the more likely they were to engage in violent behaviours, such as bullying, threatening or hitting someone. The effect of the adversity was more pronounced for boys than girls, with boys 11 times more likely to be engaged in violence, and girls four times more likely to be violent. The study also found that, in general, the cumulative effect of their traumas tended to produce higher levels of depressive symptoms among girls than boys, while boys tended to show more external aggression than girls. The study is part of the Global Early Adolescent Study, a major collaboration of the World Health Organization (WHO) and the Johns Hopkins Bloomberg School of Public Health to understand more about the development of gender stereotypes in early adolescence and their impact on adolescent health around the world. It supports a key conclusion from a major new report to be released next week at Women Deliver in Vancouver, Canada based on a global coalition of adolescent health experts: that the world will never achieve gender equality “by focusing on girls and women alone and excluding boys and men.”last_img read more

first_imgIn 2009 the first annual Festival Internacional del Paste (International Pasty Festival) was held in Real Del Monte, Hidalgo in Mexico. Three years later, the festival was attracting thousands of visitors and had become such a hit with locals that they decided to open the world’s first Cornish Pasty Museum.The classic Cornish Pasty had come a long way from its original home in Cornwall, United Kingdom, where it developed in the tin mining communities as a hearty lunch in it’s own robust package. Pastry was folded into large D-shaped pockets and stuffed with beef, turnips or swedes (rutabagas), potatoes and onions. The crimped edge was designed to be held by dirty hands during a lunch break down in the mine, and this solid crust was often discarded rather than eaten. The pasty became a Cornish community staple.A Cornish Pasty made by Warrens. Photo by David Johnson CC BY-SA 3.0In the 19th century, the British pastry lovers traveled from their home near the Celtic Sea to North America. There, they founded Cornish mining towns in places like Wisconsin, Pennsylvania, Michigan, Illinois, Montana, South Dakota, Arizona, Utah, Nevada, Colorado, and California.An engraving of Cornish miners, 1866.The Cornish miners brought their culture with them, including their love for their traditional Cornish pasty and the British sport of football (soccer). But what the Cornish miners brought to the city of Real Del Monte was truly remarkable, especially for the Mexican locals.Cornish pasties in the oven. Photo by Visitor7 CC BY-SA 3.0The mines of Real Del Monte had been a bountiful source of silver during the three centuries that Spain ruled Mexico (1521 to 1821). But by 1824, the mines were flooded, and the once prosperous city of was feeling the pinch.That’s when a group of English investors bought the mines, formed the Company of the Gentlemen Adventurers, and invited more than 130 mining engineers from Cornwall to resurrect the great mining project.Acosta Mine (Museum) in Real del Monte, Hidalgo State, Mexico.While many of these miners died of yellow fever shortly after disembarking in Veracruz, the rest finally arrived in Real Del Monte to resurrect the mining industry.They pulled Cornish steam engines through rainforests and marshes, drained the water from the Real Del Monte mines, and used their technology and experience to repair and “upgrade” the silver mines.Monument to the Miner in Real de Monte Photo by Richardth -CC BY-SA 3.0The first wave of Cornish miners and engineers were followed by many others, and by the 1840s over 300 of them were working in the Real Del Monte mines.A town in Mexico has banded together to make the worlds biggest Cornish pastyIn the 1830s and 1840s, up to 350 Cornish immigrants were working in the surrounding mines. Some of them returned to the United Kingdom, but many of the miners stayed in Mexico.The Cornish mining intervention brought more than modern technology and economic prosperity to the region. The Mexican people also fell in love with the Cornish pasty and with the Cornish game of football.Cornish pasty shop in Real del Monte.Since becoming a Mexican favorite, the dish (which they call “Paste”) has been tweaked to include peppers, hot chili sauce, chicken, and pineapples.

first_imgThe Hopi Native Americans are a cultural group often referred to as “the oldest of people” by other Native American tribes. In his Book of the Hopi, American writer Frank Waters says that they “regard themselves as the first inhabitants of America” and that “their village of Oraibi is indisputably the oldest continuously occupied settlement in the United States.” The Hopi are mainly agricultural people who live in the American Southwest, mainly in Arizona where today their Hopi reservation covers a land area of over 2,500 sq mi. They cultivate dozens of varieties of corn, beans, pumpkins, cotton, sunflower, and squash which they also use for producing tools and instruments.Hopi girlsThe Hopi are widely known for their spirituality and beliefs rooted in Animism. They believe in powerful ancestral spirits or deities called Kachinas. They can be animals or natural elements that possess the magical power of healing, bringing rainfall, and protecting the Hopi tribe.“In spirit and in ceremony, the Hopis maintain a connection with the center of the earth, for they believe that they are the earth’s caretakers, and with the successful performance of their ceremonial cycle, the world will remain in balance, the gods will be appeased, and rain will come.” – The Wind Won’t Know Me: A History of the Navajo-Hopi land dispute by Emily Benedek, published in 1992.Hopi woman, 1922. Photo by Edward S. CurtisThe Hopi tribe are the guardians of their rites and knowledge of their ancestors. Their ceremonies take place in semi-underground chambers called kivas. During their sacred rituals, the Hopi wear masks and costumes to impersonate kachinas.Hopi girl, 1922. Photo by Edward S. CurtisThe entrance to the kivas is through a tiny hole on the surface and symbolizes the gate to the underworld, while a ladder moving up above an opening on the roof represents the pathway to this world.Today, there are kivas in all traditional Hopi villages, which count 12, and are situated just below the central square.Hopi Women’s Dance, 1879, Oraibi, Arizona.

HillersNot many details about the rituals and ancestors of the Hopi are certain because they tend to carry them in great secrecy.It is believed that they descended from the Ancestral Pueblo, just like other Native Americans inhabiting the Southwest (not counting the Navajo with whom the Hopi have had a long history of disputes).Hopi woman dressing hair of unmarried girl, c. 1900. Photo by Henry PeabodyIn their stories and traditional beliefs, the Hopi lived in many different places before they finally settled on this world. They consider this World to be the Fourth and they arrived here following a difficult journey through which they searched for a home.They believe that the First World was destroyed by fire, the Second one by Ice, and the Third World by floods. They were finally led to the Fourth World by their deities.Hopi girl. Photo by Edward S. CurtisTheir oral history stretches back thousands of years which is a big reason they are believed to have one of the oldest living cultures in the world. Archaeology has affirmed their presence in the Southwest for thousands of years, and possibly longer.They introduced chieftains to their villages when they started growing in size, around the 14th and 15th centuries, to improve coordination of their daily activities.Hopi mother, 1921Despite their savage dispute with the neighboring Navajo, the Hopi’s violent history began with their first contact with the Spaniards who disturbed the tribe’s way of living.They started sending missionaries from Spain and although the Hopis pretended to accept Christianity, they have still continued their own rituals and blended elements of both.To this day, the Hopi tend to keep their traditions as much alive as possible. They still keep their centuries-old architecture of the emblematic terraced structures of stone and brick buildings.Read another story from us: The Legendary Chief Who Almost Unified All Native AmericansThey still take care of the same land where their ancestors settled and cultivate the same fields as centuries ago, while local craftsmen continue to create popular traditional jewelry and items.last_img read more

first_imgWhen it comes to international diplomacy, the simplest methods are sometimes the best. Negotiations between nations can be a tangled process, with potential disaster waiting around every turn. So much as a misplaced word can unbalance the progress of history. The United States has seen its fair share of major conflicts, yet has developed a surprisingly homespun way of putting certain visitors at ease. One infamous occasion was in June 1939, when King George VI and Queen Elizabeth left Buckingham Palace and touched down on American soil.King George VI and Queen Elizabeth at Toronto City Hall, 1939.The visit was more than just a hearty handshake across the Atlantic. Hitler was a formidable enemy and American assistance was needed. By seeing the sights and pressing the flesh, it was hoped President Franklin D. Roosevelt would supply much-needed support.Their hosts took them on a formal tour of Washington with all the whistles and bells that might be expected of such a momentous trip. However they also insisted on a down to earth approach that saw the King and Queen enjoying the countryside at Hyde Park.Franklin D. Roosevelt and Fala in the White House study, December 20, 1941.The Royals were no doubt familiar with Hyde Park, London. The American one was a little different, a town (FDR’s hometown in fact) bordering the Hudson River and part of Dutchess County New York.The President’s cottage was the perfect venue to shoot the breeze and enjoy simpler fare than the banquets the guests had been used to. But what to serve at the picnic? The answer lay in a defining American meat product… the humble hot dog.Writing in 2009, the New York Times said “the United States has developed over the years a disarming way to put its foreign guests at ease. It is to offer that most unassuming of American food items, one long associated with baseball, barbecues and occasional gastrointestinal distress.”Governor Nelson Rockefeller, Henry Cabot Lodge and New York Attorney General Louis Lefkowitz gulp hot dogs at a Coney Island hotdog stand. Photo by Seymour Wally/NY Daily News Archive via Getty ImagesThe historic face to face between King and President is thought to be the earliest example of this questionable foodstuff playing a role in world politics. Here it was hoped taste would overcome quality in this more relaxed setting, even though the food was served on a silver tray.As outlined in a 2010 Mental Floss article, the menu consisted of dogs (“if weather permits”), ham, turkey, cranberry jelly, salad and strawberry shortcake.The Roosevelts with the King and Queen of Great Britain sailing from Washington, D.C. to Mt.

As depicted by Colin Firth in the movie The King’s Speech (2010) he talked with a stutter and wasn’t confident at articulating himself.Another film, 2012’s Hyde Park On Hudson, dramatized the meeting and showed George (Samuel West) worried about the business of eating the hot dog in front of others.Roosevelt (Bill Murray) highlighted his paralysis — believed at the time to be polio, but subsequently GBS (Guillain–Barré syndrome) — to draw a comparison between the two leaders.Close up of President Roosevelt and King George VI as they drive from Union Station to the White House. June 8, 1939.In the end King George reportedly washed his dog down with a beer before going back for second helpings. The Queen, on the other hand, found it more a challenge.Quoting Dan Barry in NYT, a 2017 Smithsonian.com piece detailed FDR’s straightforward recommendation to a head of state’s culinary inquiry. “According to one story, the queen supposedly asked Roosevelt how one ate a hotdog. ‘Very simple. Push it into your mouth and keep pushing it until it is all gone,’ he is said to have told her. She elected to use a knife and fork instead of taking this folksy advice.”Following the clash of cultures and breaking of bread — or at least hot dog buns — the King and Queen returned home. President Roosevelt took to the airwaves over a year later in Christmas 1940 to announce the provision of supplies for the UK. Pearl Harbor a year later brought America squarely into the mix.The hot dog played an exceedingly minor role in proceedings. But it would be called upon again, sometimes to thaw particularly frosty relations.Soviet leader Nikita Khrushchev landed in the States in 1959. The Times describes how “At one point he stopped at a packing plant in Des Moines, where he ate his first hot dog — although at least one account says his first bite had to wait until security agents waved a Geiger counter over the dog. A mere cold war formality.”A radioactive frankfurter would be a unusual way to get rid of someone. That said, the field of international intrigue has seen stranger.Read another story from us: FDR’s Decision to Move Thanksgiving Day for Shopping Purposes Backfired WildlyThe hot dog has proved useful to successive administrations over the years. It’s sustained Americans through ball games and national holidays.
