In this premier run, Menon and Lira developed Smart Stick for Earth conditions, and predict that Smart Stick’s future will depend on using more flexible materials and incorporating a closed fluid loop in the system. A closed loop would increase the hydraulic pressure as well as overcome challenges such as leakage and outgassing required for space travel. “Lightweight joints could potentially be integrated in several space mechanisms,” Menon said. “For example, they could be implemented in miniaturized robotic systems of sample distributed units, in miniaturized grippers, or embedded in foldable/deployable systems.”Even if it takes a bit more time for Smart Stick to encounter space, the scientists already have ideas for terrestrial uses for the fluid actuator component of Smart Stick. Lira is also investigating a wearable, elastic textile called “variable structure fabric” that comfortably improves people’s posture, which is especially useful when working conditions call for long periods of standing or sitting.”The actuators in ‘Variable Structure Fabric (VSF)’ involve a new conceptual design of miniaturized fluidic actuators, which are then inserted in cloth items,” explains Lira’s Web page (VSFproject.com). “Uses for it [include] upholstery, technical clothing, underwear, and vehicle interior linings (based on Smart Stick).”Citation: Menon, C. and Lira C. “Active articulation for future space applications inspired by the hydraulic system of spiders.” Bioinspiration and Biomimetics. 1 (2006) 52-61.By Lisa Zyga, Copyright 2006 PhysOrg.com Citation: Future space devices inspired by spider legs (2006, September 7) retrieved 18 August 2019 from https://phys.org/news/2006-09-future-space-devices-spider-legs.html Are spiders ideal space travelers? Not quite, but according to a new study, their legs may be. Scientists Carlo Menon and Cristian Lira have designed and built lightweight, bendable joints based on the micro-hydraulic joint system of spider legs. The duo’s inflatable “Smart Stick” must overcome many of the harsh conditions of space, such as temperature range, pressure and atmospheric composition. In a recent issue of Bioinspiration and Biomimetics, Menon and Lira explain how most animals use muscles to bend their joints, but spiders don’t possess such extensors. Instead, these boneless arachnids have legs that are attached to the prosoma, or the main body, which pumps out fluid into the legs by contracting and expanding. Although spiders don’t have veins or even true blood, a pressurized liquid called haemolymph fills the open spaces throughout a spider’s body.”Our research approach is to find inspiration from nature to conceive new space engineering systems,” Menon told PhysOrg.com. “We realized that the characteristics of spiders’ hydraulic systems fit the need of great miniaturization and high force/mass ration required by space actuators.” The scientists’ Smart Stick, at 1 mm in diameter, is only slightly larger than a real spider’s leg. With one joint, the stick can bend about 1.8 degrees, and the scientists have developed a simple, modular system that enables the connection of several elastic joints for further bending. Each module consists of an inflatable elastic actuator that separates different segments, and a tube runs between each joint. To bend the Smart Stick, water in the tube is pressurized, causing the elastic actuators to fill with water and push the segments apart (see figure). Sensors measure the pressure and then provide feedback to the control unit, where more or less water is pressurized. Like other spiders, this Mexican Redknee (Brachypelma Smithii) tarantula bends its legs not with muscles and bones but with a pressurized fluid system that extends and contracts the joints. Scientists have created devices for space robots and even clothing based on the spider mechanism. Photo credit: Jurgen E. Haug.
New X-ray source in nearby galaxy spawns mystery © 2011 PhysOrg.com Journal information: Science Because only a few photons emitted from a binary star system are able to make their way to our planet, what we are able to see is quite limited. Because of this, very few binary star systems have been found. To get around this problem, the researchers turned to the Large Area Telescope that is part of the Fermi Gamma-ray Space Telescope. Rather than being aimed at specific points in the sky, it scans whole swaths over periods of several hours. In so doing it of course, comes across all sorts of signals. The team studied the signals that were found during one such scan and then picked out some likely candidates, then traced the signals back to their origin. One such trace revealed, for the first time, a binary star system that had been found by a systematic approach: 1FGL J1018.6-5856.What scientists know so far is that binary star systems come in two varieties; those that are microquasars, and those that are described as pulsating.Microquasars are believed to come about due to black holes pulling another star closer, creating fast jets at the top and bottom. The other, a pulsating system comes about, it is thought, when at least one of the stars in the system is a pulsating neutron star. In such a system, the two stars circle each other.The new binary discovered in the study is believed to be of the second type and emits a huge amount of gamma-rays (electromagnetic radiation of very high frequency) and lesser amounts of x-ray emissions, though the team believes that as the spin of the two stars slows, the relative amounts of radiation emitted by each will likely switch. The researchers also believe the pulsating nature of the star system was hidden by solar winds, which is why it wasn’t spotted until now.Based on their results, the team is optimistic that the same approach they’ve used can be used to find other binary systems, which would add immeasurably to the body of science surrounding such systems. More information: Science 13 January 2012: Vol. 335 no. 6065 pp. 175-176 DOI: 10.1126/science.1215895 Citation: Binary star system found by following gamma-ray signal (2012, January 13) retrieved 18 August 2019 from https://phys.org/news/2012-01-binary-star-gamma-ray.html (PhysOrg.com) — To find a binary star system, which is where two stars are in close proximity to one another, astronomers have traditionally relied on pure luck. They’d first start studying what would look like a single star, then look for a radiation signal that would provide them with more information. Such a system clearly isn’t the best approach to finding such binaries, so a group of researchers have turned the tables around so to speak, as they describe in their paper published in Science, and have found a binary by first finding its gamma-ray signal and then tracing it back to its origin.

(Phys.org)—Curtis Cooper, professor of math and computer science at the University of Central Missouri, has discovered the largest prime number to date, it’s 257,885,161 – 1. It has 17 million digits and is also a Mersenne prime (a prime number defined by the equation N=2n-1, where N and n are both prime numbers). The find was part of the Great Internet Mersenne Prime Search (GIMPS) project that uses a distributed approach to number crunching using volunteer computers. © 2013 Phys.org Explore further More information: www.mersenne.org/various/57885161.htm Prime numbers, are of course, numbers that can only be divided by themselves and 1 (and are greater than 1). They were first discovered by the famous Greek mathematician Euclid over two thousand years ago. Since that time, amateurs and experts alike have sought to discover ever increasingly larger prime numbers, though mostly for sport, as prime numbers have very few practical purposes (in recent years they have been used in cryptography). The process is difficult as there is no formula for finding them. Thus, blunt force has typically been the only way—choosing a number at random and then attempting to divide it by every number that is smaller than it is (tossing out obvious ones of course). For this reason, it wasn’t until people began building computers that really large prime numbers were discovered. Mersenne Prime numbers are named after French monk Marin Mersenne, who was the first to detail the formula for the class of special prime numbers, over 350 years ago. This latest discovery is just the 48th ever discovered. The GIMPS project has been exceptionally good at finding large prime numbers—it’s been responsible for the discovery of the largest 14 over its seventeen year history. It’s made up of 360,000 machines that together are able to calculate at peak times up to 150 trillion calculations per second. Cooper, clearly an avid member, has been credited with the discovery of two other large prime numbers found by the group. For his efforts this time, he will receive $3000. Much bigger prizes (from the Electronic Frontier Foundation) are in store for anyone that discovers a prime with a hundred million or a billion digits ($150,000 and $250,000 respectively).To make sure the number found by Cooper was indeed a prime, several other independent volunteer researchers verified it by testing it on their own computers.

Citation: Researchers propose foundering of lower island-arc crust explains continental Moho (2013, December 5) retrieved 18 August 2019 from https://phys.org/news/2013-12-foundering-island-arc-crust-continental-moho.html © 2013 Phys.org (Phys.org) —Oliver Jagoutz of MIT and Mark Behn of Woods Hole Oceanographic Institution are suggesting in a paper they’ve had published in the journal Nature, that foundering of lower island-arc crust can explain characteristics of the origin of continental Moho. This is a geophysical map showing the position of the Moho discontinuity across the Earth. The Moho is the boundary between the Earth’s crust and the mantle. Credit: AllenMcC/Wikipedia. It’s been nearly a century since seismologist Andrija Mohorovicic discovered that seismic waves traveled faster through the crust at a deeper point—approximately 25 miles down below the continents. That changeover point has since been named the continental Moho, after him. Since that time, scientists have spent considerable effort trying to explain why it’s there, but haven’t had much luck because it’s too deep to study directly. Adding to the mystery is that it doesn’t exist beneath volcanic island chains that rise above tectonic plates. In this new effort Jagoutz and Behn offer what they believe is a reasonable explanation for what has been observed—it’s all about foundering, they say.Foundering is where something sinks in water—ships founder at sea for example. In this case, the foundering, the researchers say, occurs beneath the crust—molten material hardens as it cools leaving a gap between the crust and the mantle. Foundering occurs when material from the ceiling above, falls in the mantle below. The researchers describe it as a type of crystalline rain, falling into the mantle—and whether it happens or not depends on how much heat is present. When it does occur, eventually the gap is filled and the formation of a Moho is complete.To come to these conclusions, the two researchers looked at data that describe rock samples found in Alaska and Pakistan—both have been proven to have made their way to the surface after formation some 25 miles down below, i.e. at the depth of continental Mohos—but only one showed evidence of having come from an actual Moho. The Pakistani rocks showed no sharp density contrast consistent with a Moho type boundary.This can be explained, the two researchers say, by heat distribution far below the surface. When there is sufficient heat (such as is found near volcanic areas) there is foundering, leading to the development of a Moho—when there is not, there is no such development. Seismic data backs up their claim, they say, suggesting that foundering may be the long sought answer to the question of how Mohos form. This document is subject to copyright.

Journal information: Nature Explore further More information: Foundering of lower island-arc crust as an explanation for the origin of the continental Moho, Nature 504, 131–134 (05 December 2013) DOI: 10.1038/nature12758AbstractA long-standing theory for the genesis of continental crust is that it is formed in subduction zones. However, the observed seismic properties of lower crust and upper mantle in oceanic island arcs differ significantly from those in the continental crust4. Accordingly, significant modifications of lower arc crust must occur, if continental crust is indeed formed from island arcs. Here we investigate how the seismic characteristics of arc crust are transformed into those of the continental crust by calculating the density and seismic structure of two exposed sections of island arc (Kohistan and Talkeetna). The Kohistan crustal section is negatively buoyant with respect to the underlying depleted upper mantle at depths exceeding 40 kilometres and is characterized by a steady increase in seismic velocity similar to that observed in active arcs. In contrast, the lower Talkeetna crust is density sorted, preserving only relicts (about ten to a hundred metres thick) of rock with density exceeding that of the underlying mantle. Specifically, the foundering of the lower Talkeetna crust resulted in the replacement of dense mafic and ultramafic cumulates by residual upper mantle, producing a sharp seismic discontinuity at depths of around 38 to 42 kilometres, characteristic of the continental Mohorovičić discontinuity (the Moho). Dynamic calculations indicate that foundering is an episodic process that occurs in most arcs with a periodicity of half a million to five million years. Moreover, because foundering will continue after arc magmatism ceases, this process ultimately results in the formation of the continental Moho. Mapping the Moho with GOCE

DOI: 10.1103/PhysRevLett.116.184501ABSTRACTBy means of ultrathin silicon membranes excited in the low ultrasound range, we show for the first time that it is possible to form two-dimensional Chladni patterns of microbeads in liquid. Unlike the well-known effect in a gaseous environment at the macroscale, where gravity effects are generally dominant, leading particles towards the nodal regions of displacement, we show that the combined effects of an ultrathin plate excited at low frequency (yielding to subsonic waves) together with reduced gravity (arising from buoyancy) will enhance the importance of microstreaming in the Chladni problem. Here, we report that for micrometric beads larger than the inner streaming layer, the microscale streaming in the vicinity of the plate tends to gather particles in antinodal regions of vibrations yielding to patterns in good agreement with the predicted modes for a liquid-loaded plate. Interestingly, a symmetry breaking phenomenon together with the streaming can trigger movements of beads departing from one cluster to another. We show that, for higher modes, this movement can appear as a collective rotation of the beads in the manner of a “farandole.” © 2016 Phys.org This document is subject to copyright.

Journal information: Physical Review Letters Explore further Several centuries ago, it was noted that covering a plate with flour and causing the plate to vibrate resulted in the flour forming into different patterns, depending on the frequency of the vibration. Later it was noted that sand poured over the back of violin demonstrated the same types of properties—such patterns have subsequently been called Chladni Patterns and they have been used in designing musical instruments and other applications over the years. In this new effort, the researchers wondered if the same types of patterns would emerge in particles that exist in a water solution.To find out, the researchers placed an amount of multi-sized microbeads into a container that had a membrane stretched across a base at the bottom, similar to a drum. They next filled the container with water and then watched (and filmed) what happened when the membrane was caused to vibrate at different frequencies.The researchers found that the beads did migrate to form patterns, very similar to those in a dry environment, and they could be changed by adjusting the vibration frequency—but they also found that there were some differences. First, the patterns were not created the same way, instead of the finer grains getting pushed to nodes, they actually moved in the opposite direction, piling up at antinodes, forming what might be described as inverse Chladni patterns—due to a phenomenon known as acoustic streaming. But perhaps, more amusing, the team also found that under the right circumstances, i.e. causing vibrations that were off the resonant frequency, the microbeads could be caused to move in clusters around an outer circle, much like, they note, dancers engaged in a farandole.The researchers note that their findings could have practical applications, like using vibrations to move particles in a fluid across a surface to a desired location in industrial applications, or more exotically, to move cells on a surface into a desired pattern before allowing them to grow.

Using MAGIC telescopes and NASA’s Fermi spacecraft, an international team of astronomers has discovered a new source of very high energy gamma-ray emission around the supernova remnant (SNR) G24.7+0.6. The detection of the new source, designated MAGIC J1835–069, is detailed in a paper published December 12 on the arXiv pre-print server. The fading ghost of a long-dead star Supernova remnants are basically leftovers of massive stars that ended their lives in huge explosions called supernovae. Astronomers generally distinguish three types of SNRs, one of which is the composite SNR—these having rapidly expanding shells from the supernova blast wave accompanied by wind nebulae powered by young pulsars formed in the explosions. Observations show that composite SNRs are known to accelerate particles to very high energies (VHE), up to hundreds of TeV or beyond, in their expanding shocks or the relativistic wind surrounding the energetic pulsar. Therefore, such objects are excellent targets for observations focused on finding new sources of VHE emission.Located about 16,300 light years away, SNR G24.7+0.6 is an example of a middle-aged (around 9,500 years old) radio and gamma-ray composite SNR. A group of astronomers have carried out a study of this remnant using the MAGIC (Major Atmospheric Gamma Imaging Cherenkov Telescopes) system at the Roque de los Muchachos Observatory in the Canary Islands and the Large Area Telescope (LAT) onboard NASA’s Fermi Gamma-ray Space Telescope. Data provided by these telescopes allowed the team to identify a VHE emission from an extended source located 0.34 degrees away from the center of G24.7+0.6, which received designation MAGIC J1835–069.”In this paper, we study the interesting region centered around SNR G24.7+0.6 with Fermi-LAT in the energy range between 60 MeV and 500 GeV. We also explore with the MAGIC telescopes the region around it to investigate the spectral behavior above 150 GeV in order to constrain the emission region observed by Fermi-LAT around the SNR,” the researchers wrote in the paper.The emission from MAGIC J1835–069 was found at energies above 150 GeV and has been detected up to 5 TeV. The spectrum of this source is well-represented by a power-law function with spectral index of 2.74. The emission from MAGIC J1835–069 also has a projected size of approximately 98 light years and showcases an extended morphology. The newly found source lies between two known extended sources detected above 10 GeV by Fermi-LAT, namely FGES J1836.5–0652 and the FGES J1834.1– 0706.The origin of VHE gamma-ray emission from MAGIC J1835–069 remains uncertain due to the complexity of the neighboring region of G24.7+0.6. However, the authors of the paper suggest that it could be explained by cosmic rays accelerated within the remnant interacting via proton-proton collisions with the carbon monoxide-rich surrounding medium.”The detected gamma-ray emission can be interpreted as the results of proton-proton interaction between the supernova and the CO-rich surrounding,” the researchers concluded.

Kolkata: Jadavpur University has decided to recruit female guards for strengthening security on the campus.The decision was taken at a meeting in the university on Monday afternoon involving 36 stakeholders and senior administrative officials including Vice-Chancellor Suranjan Das and Registrar Snehamanju Basu “The male security guards have often complained of facing difficulties while handling women related issues and have avoided doing the same. Checking of women is a sensitive issue. Hence, we have decided to recruit women security guards. V-C has already given me the consent,” the Registrar said. The university is hopeful that this move will be able to prevent outsiders’ entry into the varsity campus in a more effective manner.

Obesity is increasing more rapidly in the world’s rural areas than in cities, according to a study of global trends in body-mass index (BMI). The study, published in the journal Nature, analysed the height and weight data of over 112 million adults across urban and rural areas of 200 countries and territories between 1985 and 2017. Height and weight can be used to calculate BMI, an internationally recognised scale which tells us whether an individual has a healthy weight for their height, said researchers led by Imperial College London in the UK. Also Read – Add new books to your shelfThe study found that from 1985 to 2017, BMI rose by an average of two kilogrammes per square metre (kg/m2) in women and 2.2 kg/m2 in men globally, equivalent to each person becoming five to six kg heavier. Over half of the global rise over these 33 years was due to increases in BMI in rural areas. In some low and middle income countries, rural areas were responsible for over 80 per cent of the increase. The team found that since 1985, average BMI in rural areas has increased by 2.1 kg/m2 in both women and men. Also Read – Over 2 hours screen time daily will make your kids impulsiveHowever, in cities, the increase was 1.3 kg/m2 and 1.6 kg/m2 in women and men respectively. In 1985, urban men and women in over three quarters of the countries had a higher BMI than their rural counterparts, they said. Over time, the gap between urban and rural BMI in many of these countries shrank or even reversed. “The results of this massive global study overturn commonly held perceptions that more people living in cities is the main cause of the global rise in obesity,” said Professor Majid Ezzati of Imperial’s School of Public Health. “This means that we need to rethink how we tackle this global health problem,” Ezzati said. The team found important differences between high-, middle-, and low-income countries. In high-income countries, the study showed that BMI has been generally higher in rural areas since 1985, especially for women. The researchers suggest this is due to the disadvantages experienced by those living outside cities: lower income and education, limited availability and higher price of healthy foods, and fewer leisure and sports facilities. “Discussions around public health tend to focus more on the negative aspects of living in cities,” said Ezzati. “In fact, cities provide a wealth of opportunities for better nutrition, more physical exercise and recreation, and overall improved health, which are often harder to find in rural areas,” he said. Rural areas in low- and middle-income countries have seen shifts towards higher incomes, better infrastructure, more mechanised agriculture and increased car use. These factors not only bring numerous health benefits, but also lead to lower energy expenditure and to more spending on food, which can be processed and low-quality when sufficient regulations are not in place. All these factors contribute to faster increase in BMI in rural areas, researchers said. “As countries increase in wealth, the challenge for rural populations changes from affording enough to eat, to affording good quality food,” said Ezzati. The main exception to the global trend was sub-Saharan Africa where women gained weight more rapidly in cities. This was possibly because of more low-energy work, such as office work, less need for physical domestic tasks and greater access to processed foods, researchers said.
In 2016, a research team reported conclusive evidence of the oldest microbial life to be found on Earth, fossilized in rocks in Greenland. The stromatolite structures are believed to be the remnants of bacteria that grew on the bed of a shallow sea, 3.7 billion years ago. Two decades before, in 1996, another team of scientists stirred up a debate over their claim to have found signs of life in 3.8-billion-year-old rocks from Akilia Island, also in Greenland. As the results could not be replicated — one of the main principles of the scientific method — their conclusions are considered unreliable, but have formed the basis for a number of subsequent research efforts.However, scientists are now faced with the possibility of an even earlier date for the beginning of life on Earth. According to a new study, life might have initially appeared on Earth 3.95 billion years ago.Newfoundland, CanadaThe team, led by geologist Tsuyoshi Komiya from the University of Tokyo, examined samples from the Torngat Mountains in Labrador, a part of the Canadian province of Newfoundland. This is one of the few areas on the globe where rocks that were formed at the very end of the Hadean era can be found — the period when Earth had cooled just enough to develop a solid crust.The first oceans were beginning to form as water vapor condensed, and current theories suggest that somewhere in these warm shallow waters, complex chemical molecules evolved into the first lifeforms.The findings of Komiya’s team, published in the journal Nature in September 2017, conclude that the rocks contain material generated by microbes. Komiya told LiveScience that the rocks were collected from an area that was quite remote, inhabited by a number of polar bears and “far from any village or town.”Scientists have analyzed 3.95-billion-year-old rocks from northern Labrador.But this new study might turn out to be just as controversial as the one from 1996. As Sarah Kaplan writing for the Washington Post comments, “Not all researchers are convinced.” Other scientists are keen to take a look at the rocks to verify Komiya’s claims.The specific element of the rock samples that most intrigued the scientists was tiny nodules of graphite, a material made of layers of carbon atoms.“Carbon comes in two stable isotopes: carbon-12, which is the most common, and carbon-13, which is rarer and slightly heavier. Life prefers carbon-12 because it is more reactive,” according to ZME Science. The main premise behind the Labrador study is that evidence of life can be inferred by looking at the ratio of these carbon isotopes.Komiya and his colleagues say that tiny blobs of graphite found in the rock are the oldest fossils ever discovered.This is how the team surmised the the graphite samples have a biological origin. “This is a biogenic signature,” Komiya told the Washington Post.Komiya and his colleagues have also addressed some of the issues for which the 1996 study was so hotly disputed. The earlier study was also based on the study of carbon isotopes however, according to Nature, “Some researchers say the carbon cannot be proven to have a biological origin…. Others have suggested that the rock is not as old as originally thought.”6 Mysterious Islands From Around The WorldThe research team believe the find in Labrador is exciting because the graphite was enclosed by the rocks in a way that suggested life didn’t originate as contamination from a later period.How life actually began still remains a mystery. Scientists firmly state that all available evidence indicates planet earth was formed 4.54 billion years ago and water soon appeared on its surface. Several genesis of life theories have been put forward, most of them centered on the idea that biology started in the water.The 1953 Miller-Urey Frankenstein’s monster-type experiment demonstrates that amino acids — the building blocks for life — can be synthesized from inorganic molecules in the atmosphere by lightening. Windows to the Universe describes the set up: “They designed an apparatus which held a mix of gases similar to those found in Earth’s early atmosphere over a pool of water, representing Earth’s early ocean. Electrodes delivered an electric current, simulating lightning.”When the two biochemists analyzed the contents of the water after running the experiment for one week, not only did they find organic molecules, but they had coalesced into clumps called coacervates. While for many this is compelling evidence that life arose spontaneously on our young planet, others argue that the probability for such a scenario is unfathomably small.Natural-color image of an ice island off the coast of Labrador.Another theory suggested by Irish scientist J.D. Bernal in 1949 postulates that life began in clay. We don’t mean a parade of little clay-model people, rather that clay minerals would attract the right mixture of chemicals for life to begin. Expanding on his ideas became a lifetime obsession for the late Alexander Graham Cairns-Smith, an organic chemist from the University of Glasgow. Cairns-Smith considered the regimented replication of DNA began on a clay substrate.Of course, there are many scientists who think that life actually began on another planet or in space, and was transported to Earth by celestial bodies such as comets or asteroids.Read another story from us: Electromagnetic Discovery in the Great Pyramid: Could it Concentrate Energy in Certain Chambers?So far, Canada is the place which has produced most of the evidence of primordial life in the world. Komiya stated for LiveScience that future analysis of the graphite and associated minerals from the Torngat Mountains “could shed light on the origin and evolution of life on Earth.”
Ukraine has witnessed a surge in reviving what is believed to represent their ancient culture, which dates to pre-Christian times. This revival found its way into art and fashion, where it is probably most visible. However, the Ukrainians are not exclusively enjoying the expression of their national identity — the global fashion world is enthralled by some of the pieces they have brought to the table. The Slavic workshop Treti Pivni (translated as Third Rooster) has done a remarkable photo series with women and children in traditional Ukrainian headdresses. The team is made of photographers, stylists, and makeup artists who have fallen in love with this beautiful decorative tradition.As reported by Vogue, “This wave of supporting homegrown designers and local production has contributed to a revival of Ukrainian folk staples, most noticeably the much-blogged-about vyshyvanka and zhupan, courtesy of contemporary Kiev-based designers like Vita Kin and Yuliya Magdych.”Photo by Treti PivniPhoto by Treti PivniPhoto by Treti PivniOne of the additions to the list is the vinok, a traditional and amazingly crafted flower crown. Vinoks were a part of Ukrainian culture for centuries before being banned under communism, along with many other diverse national traditions. The traditional symbolism was worn only by bold individuals who wanted to openly defy the dominant system. The use of vinoks and similar items was closely monitored all throughout Soviet rule, but especially in the 70s and 80s.Now Ukrainians have begun to turn back towards what is thought to be traditionally theirs. The positive feelings towards this symbolism have spread very fast. Nowadays, vinoks are sold all throughout the country — you can even buy one at a metro-station kiosk. These disposable vinoks are made of fake roses and daffodils and spiced up with colorful ribbons.Notwithstanding their more than pleasing hippy-like aesthetic, for Ukrainians, the vinok is so much more than an accessory. The intricate flower wreaths were used to signify the status of females in society. Young girls would decorate their hair with flowers and ribbons making a simple head band. In summer and spring, they would use fresh flowers, and in winter they crafted fake ones from paper and cloth.When the girls reached maturity and were ready for courtship the wreaths would become ever more detailed and intricate. Specific flowers and designs would differentiate girls that are to be approached with wedding offers and those who are yet to come of age. Alexandre Mihailovic, a specialist in Slavic Literature explained for Vogue, “The latter practice in Ukraine of wearing the wreath is meant to signal the purity of a young woman before marriage.”At a wedding, female friends of the bride would weave the most beautiful flowery headpieces they had ever worn. Incredibly, they managed to weave the whole piece in only one day. As Mihailovic shared, “In both Ukraine and Russia, both spouses-to-be would wear crowns during the wedding ceremony, apparently continuing an ancient tradition from Byzantium.” However, the Ukrainian case is different as in Russia unmarried girls did not wear headpieces.Photo by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniPhoto by Treti PivniAfter being banned for such a long time, modern girls are returning to their roots. The original practice of crafting and wearing the vinok is making a comeback, together with reviving the tradition of embroidery. It is a way for Ukrainians to reconnect with their ancient culture and celebrate their traditional heritage.Read another story from us: The Mysteries and Meanings Behind 6 Fascinating SculpturesInspired by this surge of interest a group of Ukrainian stylists and photographers set out to recreate vinoks from different parts of the country. They built a presence on social media where they showcase beautiful portraits of women of various ages wearing their miraculous creations. Their goal is to celebrate their culture and showcase it to the world.
