A Smarter Way to Grow Graphene

first_img Producing graphene from carbon dioxide The current methods of isolating graphene each have problems. The most common, known as micromechanical cleavage, in which sheets are sheared off of a larger crystal, doesn’t reliably produce graphene samples that are large enough for applications.Another method, in which the atomic structure of a substrate is used to seed the growth of the graphene, known as epitaxial growth, doesn’t yield a sample with a uniform thickness of graphene layers, and bonding between the bottom graphene layer and the substrate may affect the properties of the carbon layers.The Brookhaven group based their technique on this second method, except that they were able to grow the graphene in a controlled, layer-by-layer manner. The substrate they chose is the rare metal ruthenium, and while the bottom graphene layer does interact strongly with it, the next layer up is almost completely detached, only weakly electrically coupled to it, and behaves much like free-standing graphene.“This second layer retains the inherent electronic structure of graphene,” Brookhaven physicist Peter Sutter, who led the work, told PhysOrg.com. “Thus, our findings may represent a long-sought route toward rational graphene synthesis and the creation of high-quality graphene for applications in electronic devices and sensors.”Graphene has several properties that make it desirable for electronics, including its very high carrier mobility—that is, electrons in graphene can roam rather freely. Graphene can respond to a single gas molecule, making it very attractive as a detector material for sensors.The Brookaven group’s growth process takes place at high temperatures. To start, the researchers caused carbon atoms to become absorbed within the ruthenium by heating the entire sample to 1150 degrees Celsius (ºC). The sample was then cooled to about 850 ºC, which caused large amounts of the absorbed carbon to rise to the surface of the ruthenium. The carbon formed single-layer lens-shaped islands about 100 micrometers (millionths of a meter) in width, dotting the entire substrate surface.Eventually, the islands grew into a complete first graphene layer. And at about 80 percent coverage, the growth of the second layer began.Sutter and his group observed the growth and studied the graphene’s properties using various instruments, including a scanning electron microscope and a low-energy electron microscope.Citation: Peter W.

Light within a light offers CFL efficiency with incandescent bulb shape

first_img The advantage of the new Energy Smart compact fluorescent lamp (CFL) is that it offers CFL efficiency along with the more aesthetic pleasing appearance of a typical incandescent bulb. The new light has the same size and dimensions of an old 60-watt bulb, which may make it attractive for fixtures in which the bulb is visible, or possibly for inexpensive ceiling fixtures designed to clip on to round bulbs.”The all-glass design, which I said would be out next year, combines that T2 spiral fluorescent tube with an electronics package contained in the neck of the lamp,” John Strainic, GE global product general manager, explains in the video. “So that gives you the profile of an incandescent shape…so it’s like building a ship in a bottle.”Strainic said that some very leading-edge patents were used for the process of cutting and resealing the bulb. The final bulbs will be frosted white, so most likely the inner fluorescent spiral won’t be visible. GE plans to make the new bulb available on December 28 at Target, in January at selected Ace Hardware stores, and everywhere else (including Walmart) around Earth Day 2009 (April 22). via: Gizmodo© 2008 PhysOrg.com A video clip of General Electric’s new Energy Smart CFL bulb, containing a fluorescent bulb in an incandescent-shaped outer bulb.

Yahoo is Going Portuguese Hound to Outwit Twitter

first_imgYahoo Meme In Brief: Yahoo! integrates ask and search sites This document is subject to copyright. 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. Explore further According to David Ruiz, a blogger, systems analyst and senior programmer in Brazil, Yahoo has released a Twitter clone called Yahoo Meme in Portuguese. The Yahoo Meme is by invitation only. David Ruiz received his invitation to the alpha-version of the Twitter-like social networking site. Interestingly, Yahoo Meme uses a dog instead of the familiar Twitter bird. Mr. Ruiz says the term “meme” is an adaptation of the scientific observations of Richard Dawkins in his book, “The Selfish Gene”. On the Internet, a “meme” is used to describe a sort of fever of popular content available to everyone. In the Yahoo sense of the term for its new social networking site, Yahoo Meme, it is a term which expresses the notion of free and expanded, within the context of the original idea. Simply put, Yahoo Meme is easy to access and easy to use. A click on the call, sign in and name your meme, attach your url, give a less than a 100 character description and you are Go. A screen lists all the meme images which allows users to verify who is meme-ing you. Users can post videos, images, music and text in the same way as Twitter. The search feature needs some tweaking, but it is pretty new.According to Ruiz, the Alph-phase is closed and he has only a few invites available for distribution. He distinguishes Twitter from Memes conceptually, saying memes is more like the “fever” of the moment. The actual differences between Twitter and Yahoo Memes may be a distinction without a difference. Except Yahoo Memes is in the Portuguese language.© 2009 PhysOrg.com Citation: Yahoo is Going Portuguese Hound to Outwit Twitter (2009, May 15) retrieved 18 August 2019 from https://phys.org/news/2009-05-yahoo-portuguese-hound-outwit-twitter.html Brazil, a Portuguese speaking country is the 10th largest economy in the world and Yahoo has decided to get in on the action by coming up with a clone Twitter.

Google adds voice and video to Google Talk on Android smartphones

first_img(PhysOrg.com) — Users of Google’s Android OS on their Nexus S smartphones can now smile a little more as their friends will be able to see it; Google has (finally) added video and voice chat as a part of a native Android app. Third party apps that let users video chat on their Android phones (Fring, Qik, etc.) have been around awhile, as has a native app on the iPhone (FaceTime); with this move, Google is finally catching up with everyone else by adding both video and voice to Google Talk; something users have been able to do on their personal computers for quite some time. Although, sadly, the new additions will only be available for Nexus S phones (Nexus One phones don’t have a front facing camera) it will likely create waves in the smartphone market as it offers yet another way for users to communicate with one another using their data network, rather than the cell channel, which means users can talk with other users without using any of their voice minutes. More information: googlemobile.blogspot.com/2011 … r-android-phone.html Citation: Google adds voice and video to Google Talk on Android smartphones (2011, May 2) retrieved 18 August 2019 from https://phys.org/news/2011-05-google-voice-video-android-smartphones.html Android 2.3 Gingerbread expected in the next few days Explore further © 2010 PhysOrg.com Google announced the update on their blog and says that the updates will happen over the air, over the next few weeks (for 2.3.4 phones; other 2.3+ devices will have to wait for a future update). The new feature will work with both Wi-Fi and 3/4G Wireless networks (upping the stakes for Facetime which only works with Wi-Fi). Once updated, users will find a video or voice chat button next to their contacts on their contacts list. To connect, all they’ll need to do is click the button.Once updated, users of Nexus S phones will be able to video and voice chat as well as text with other Nexus S phone users; they’ll also be able to do the same with those running Google Talk on their PC or with tablet users running Honeycomb. Text messages will be overlaid on the video screen and video can be paused while other apps are run (the audio keeps going).Clearly Google, still the new player in town, is serious about its venture into the smartphone market, and will continue to add functionality to Android as it moves from a follower, to a leader in the field.

ATLAS preprint: arxiv.org/abs/1207.7214CMS preprint: arxiv.org/abs/1207.7235 Explore further Endgame for the Higgs Boson Journal information: arXiv More information: Citation: CERN teams post Higgs Boson papers – one ups its sigma level of certainty (2012, August 2) retrieved 18 August 2019 from https://phys.org/news/2012-08-cern-teams-higgs-boson-papers.html (Phys.org) — The two teams working (and causing headlines around the world) at the CERN Large Hadron Collider CMS and ATLAS, have both uploaded papers describing their work in searching for evidence of the particle that is believed to explain why matter sticks together, the elusive Higgs Boson, to the preprint server arXiv. In their paper, ATLAS has bumped up its sigma level of certainty from 5.0 to 5.9 while CMS has kept its level at the 4.9 to 5 range. The sigma levels are indicators physicists use to gauge how sure they are of their results. 5.0, for example indicates the researchers believe there is a five in ten million chance that the signals they’ve seen are due to something other than what they believe it to be; in this case, evidence of a Higgs boson. 5.9 would bump up the likelihood to two in a billion.It’s important to note that both teams are still calling what they’ve found to be something “Higgs like” rather than boasting of the discovery of the actual boson. This is because neither team has actually seen the boson, instead, they rely on measurements of particles that are thought to come into existence as a Higgs decays; according to theory, it’s only supposed to last for the tiniest fraction of a second, too little time to actually see or record it. It’s also important to note that the sigma numbers aren’t measurements of how certain the researchers are that what they’ve found is the Higgs, instead they are numbers that represent how certain the teams are of what they’ve measured. This means it’s possible that all their measurements and numbers are right, but whatever caused them to come about isn’t an actual Higgs, but something else that is both close to a Higgs and un-described in the Standard Model. There is no statistical number to demonstrate how sure they are of that.What this all means is that both teams, and most physicists who study such things, are pretty sure that the work at CERN has proven that the Higgs boson does indeed exist and that further study will one day allow for the removal of the Higgs-like tag. On the other hand, if it turns out that what the teams have been measuring is due to something else, well, that will mean having to edit the Standard Model, which is a description physicists have come up with to describe all of the ingredients at their most basic level, that make up everything that exists. This artist’s graphic shows the underground ATLAS detector along the 17-mile subsurface tunnel, the Large Hadron Collider at the Swiss-Franco border.

Boronbased atomic clusters mimic rareearth metals

first_img More information: “Mimicking the magnetic properties of rare earth elements using superatoms” Shi-Bo Cheng, PNAS DOI: 10.1073/pnas.1504714112 An Alchemist’s Dream: Superatoms Mimic Elements Prior studies by this group demonstrated that TiO-, ZrO-, and WC- were similar to Ni-, Pd-, and Pt-, respectively. This work had established that by simply counting the valence electrons of the atomic units comprising the cluster, certain clusters of atoms could behave as a superatom counterpart to isovalent, atomic anions. They wanted to apply this same technique to a boron-doped lanthanum, which should have six valence electrons in its neutral LaB cluster. Furthermore, if the LaB cluster does behave like Nd, then there should be four unpaired electrons in the cluster’s valence, mimicking neodymium’s magnetic properties.Using photoelectron spectroscopy, Cheng et al. found that LaB adiabatic ionization energy (ADE, also the electron affinity) measurement was 0.909 +/- 0.025 eV. Vibrational frequencies were measured with four distinct peaks around the largest peak that represents neutralization of the LaB- anion.Experimental results were compared to theoretical calculations in which the lowest energy state was discerned from various spin multiplicities of both LaB- and LaB. Theoretical calculations showed that the lowest energy conformation of LaB- has three unpaired electrons (spin multiplicity of 4) and LaB has four unpaired electrons (spin multiplicity of 5). Theoretical vibrational energies correspond to the measured vibrational energies found using photoelectron spectroscopy. Additionally theoretical ADE and vertical detachment energy (VDE) of both LaB- was very close to the experimental values with LaB- ADE calculated to be 0.947 eV. This provides strong evidence that LaB likely has four unpaired electrons and six electrons, total, in its valence, which is analogous to Nd. By combining the vibrationally-resolved photoelectron spectroscopy and high-level theoretical calculations, Cheng et al. have provided compelling evidence that LaB has four unpaired electrons and six electrons, total, in its valence, which is analogous to Nd. Similar experiments were further performed to examine whether such similarity is preserved between another boron-doped superatom cluster (NdB) and its isovalent rare earth counterpart europium. Experimental and theoretical results confirmed that the lowest energy state of NdB has seven unpaired electrons, analogous to europium’s valence. Rare Earth elements, found in the f-block of the periodic table, have particular magnetic and optical properties that make them valuable commodities. This has been particularly true over the last thirty years as more technologies use rare earth metals in their components, including audio speakers, computer hard drives, camera lenses, MRI imaging, television screens, and computer screens.

Shi-Bo Cheng, Cuneyt Berkdemir, and A. W. Castleman, Jr. from the Department of Chemistry and Physics at Pennsylvania State University have shown that boron-doped lanthanide superatom clusters mimic the valence electron configuration of certain rare earth elements, and may serve as rare earth analogs. Their work is published in the Proceedings of the National Academy of Sciences.Cluster chemistry involves combining atoms or molecules in such a way that they are considered something in between an isolated atomic or molecular species and bulk material. This field gained prominence when nanomaterials and semiconductors became popular areas of research. Superatom clusters are a subcategory of cluster chemistry in which a cluster of atoms behaves as though it were single atomic species. The combined valence electrons in a superatom cluster are no longer identified with a particular nucleus, but behave as if they are the valence of a single atomic structure.Early research into superatom clusters found that certain atoms or atomic combinations tended to cluster into particular numbers, known as magic numbers. Cheng et al.’s research looked at what they have dubbed a “magic boron” counting rule, in which boron combined with a lanthanide in a superatom cluster will contribute three unpaired electrons to the number of unpaired electrons in the lanthanide atom’s valence.Cheng et al. investigated whether the magnetic properties of the diatomic boron-doped lanthanum clusters and boron-doped neodymium clusters behaved like neodymium (Nd) and europium (Eu), respectively. They theorized that the spin characteristics of these particular superatom combinations should be similar to those of their isovalent rare earth counterparts, and would therefore display analogous magnetic properties. They first constructed the superatom cluster, then tested its valence properties using photoelectron spectroscopy and compared their experimental results to theoretical calculations.

Expression patterns of cryptochrome genes in avian retina suggest involvement of Cry4 in light-dependent magnetoreception, Journal of The Royal Society Interface (2018). DOI: 10.1098/rsif.2018.0058AbstractThe light-dependent magnetic compass of birds provides orientation information about the spatial alignment of the geomagnetic field. It is proposed to be located in the avian retina, and be mediated by a light-induced, biochemical radical-pair mechanism involving cryptochromes as putative receptor molecules. At the same time, cryptochromes are known for their role in the negative feedback loop in the circadian clock. We measured gene expression of Cry1, Cry2 and Cry4 in the retina, muscle and brain of zebra finches over the circadian day to assess whether they showed any circadian rhythmicity. We hypothesized that retinal cryptochromes involved in magnetoreception should be expressed at a constant level over the circadian day, because birds use a light-dependent magnetic compass for orientation not only during migration, but also for spatial orientation tasks in their daily life. Cryptochromes serving in circadian tasks, on the other hand, are expected to be expressed in a rhythmic (circadian) pattern. Cry1 and Cry2 displayed a daily variation in the retina as expected for circadian clock genes, while Cry4 expressed at constant levels over time. We conclude that Cry4 is the most likely candidate magnetoreceptor of the light-dependent magnetic compass in birds.center_img Journal information: Journal of the Royal Society Interface Credit: CC0 Public Domain Birds that are able to migrate great distances obviously have some form of navigation system—they stop at the same places and have very clear destinations in mind. But how do they do it? In recent years, some in the field believed it had to do with iron-rich cells in their beaks serving as mini-compasses, but this theory has had some problems, such as how the birds translate beak sensations to directional signals. In this new effort, the researchers suggest it is not the cells in the beak that are responsible, but a type of protein that exists in their eyes. The researchers came to this conclusion by studying the brains, muscles and eyes of zebra finches. More specifically, they studied Cry1, Cry2 and Cry4, proteins associated with the circadian clock. The researchers found that Cry1 and Cry2 levels tend to rise and fall throughout each day, but Cry4 remains constant, suggesting it has another purpose.The researchers chose to study these particular proteins because they are made of a type of molecule that sometimes has an odd number of electrons, leaving some unpaired, and thus sensitive to a magnetic field. They also found that Cry4 tends to exist in clusters in a part of the bird retina that tends to get a lot of light and which is sensitive to blue light—this is important because prior studies have shown that birds are only able to navigate when blue light is available. Taken together, the evidence suggests that the protein plays a strong role in navigation.The study does not prove that the Cry4 protein is the key to bird navigation, but it makes a strong case for it. Earlier this month, a Danish and German team of researchers studying robins found that Cry4 levels also remain constant each day, but rise during the migratory season. A team of researchers at Lund University has found evidence that suggests a certain protein plays a prominent role in bird navigation. They have published their findings in Journal of the Royal Society Interface.last_img read more

CPIMBJP join hands at grassroot level to fight TMC BJP describes it

first_imgKolkata: Arch-rivals BJP and the CPI(M) have joined hands at the grassroot level in Nadia district to defeat the Trinamool Congress in the upcoming panchayat polls in West Bengal. Maintaining that it was not a “formal seat sharing adjustment”, a district level CPI(M) leader said that the party had to opt for seat adjustment in many seats as several villagers wanted a one-to-one fight against the TMC. The CPI(M), with an opposite ideology to that of the BJP, never loses an opportunity to describe the saffron party as a “divisive force”. Also Read – Heavy rain hits traffic, flights The BJP’s north Nadia district unit president termed the development as an “isolated incident”. The bonhomie first came to light in the last week of April when both the parties organised a joint protest rally in Karimpur-Ranaghat area of Nadia district against the alleged violence of the TMC during the panchayat poll process. Cadre of both parties carried their respective flags during the protest programme. CPI(M) Nadia district secretary and state committee member Sumit De agreed that there have been adjustments at the grassroot level in many seats as several villagers were in favour of a one-to-one fight. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killed It has nothing to do with the party’s policy, he added. “Yes, there have been adjustments at the grassroot level. In many seats as the villagers had wanted one-to-one fight, we had to respect it and act accordingly. But it is not that there have been several rounds of discussions between parties and it is a formal seat sharing adjustment,” De told PTI. Senior CPI(M) leader and state committee member Rama Biswas, who was present at the joint rally of the BJP and CPI(M), said that a rally had been taken out by villagers against the violence of the TMC. West Bengal BJP president Dilip Ghosh too admitted that supporters of the BJP and the CPI(M) were present at the rally “I have received information that we had called a rally against the violence of the TMC. CPI(M) workers also came and joined our protest rally as they too were attacked,” Ghosh told PTI. A senior state BJP leader who did not wish to be named, said in areas where the BJP could not field a candidate “it has given enough hints to the voters and party cadres to counter the TMC which has unleashed violence”. Agreeing that such “isolated incidents” had taken place, the BJP north Nadia district president Mahadeb Sarkar told PTI, “In some seats where we could not field candidates, our workers at the grassroot level have extended support to independent candidates”. “In most cases, these independent candidates are actually CPI(M) workers”, he said. In several gram panchayat seats of Nadia-Karimpur area, BJP candidates were asked to withdraw their nominations so that the CPI(M) could fight against the TMC and vice-versa, a district BJP leader said. In those seats, the party (either CPI(M) or BJP) which has not fielded any candidate is campaigning for the other one to defeat the TMC, the BJP leader of Nadia’s Karimpur area, who did not wish to be named, said. CPI(M) central committee leader Sujan Chakraborty said few “isolated incidents” should not to used to judge the CPI(M)’s political line against BJP. “We are the only party in India which has the most clear approach against BJP and its communal policies. We are not like the TMC which is not serious about fighting BJP. Our policies should not be judged based on isolated incidents. In panchayat poll such isolated incidents do happen. You will find it in other parties also”, Chakraborty said. The TMC claimed that the political development in Nadia only proves that the BJP and the CPI(M) are having a “tacit understanding in Bengal”. “We are not surprised at this development as we were aware of such developments in various districts. Only the TMC is serious about fighting the BJP and its anti-people policies,” TMC secretary general Partha Chatterjee said. According to West Bengal SEC (State Election Commission) sources, of the 48,650 seats in 3,358 gram panchayats, 16,814 were uncontested and of the 9,217 seats in 341 panchayat samitis, 3,059 were uncontested. In the 20 zilla parishads, 203 of the 825 seats were uncontested, they said.last_img read more

A new study has found that if we are in a relationship, we are more likely to be attracted to faces resembling our own, but for single people opposites attract.“For the first time, we have observed how our partnership status affects who we find attractive,” says Jitka Lindova from Charles University in the Czech Republic. The team showed a series of photographs of faces to university students and asked them to rate their attractiveness.  The photographs were digitally manipulated so that the resemblance to the student was modified. Images were of an individual of the opposite sex, whose face had been manipulated to look either more or less similar to the student. They were also presented with images of a same-sex individual manipulated in the same way. “We found that single participants, those not in relationships, rate dissimilar faces as more attractive and sexy than self-resembling faces,” Lindova said. This was observed when participants rated both same-sex and opposite-sex faces.

The study was published in the journal Frontiers in Psychology. “This might be a relationship maintenance strategy to prevent us from finding alternatives to our own partner, or perhaps self-resemblance becomes more important in terms of the social support we expect receive from relatives, which are known as kinship cues,” Lindova explained.last_img read more

Food processing Horticulture dept looks to upgrade packhouse facility at Barasat to

first_imgKolkata: The state Food Processing & Horticulture (FP&H) department is taking measures to revamp its packhouse facility at Nilganj in Barasat, after exports of fresh vegetables to the European Union (EU) have suffered, with the packhouse that was set up more than 10 years ago, lying in neglect for more than 10 months.”We are going for open tender to select a company that will revamp the packhouse. The tender will be opened shortly,” said Abdur Rezzak Mollah, minister of FP&H. Also Read – Rain batters Kolkata, cripples normal lifeAccording to sources in the FP&H department, EU has always been very stringent regarding quality when it comes to exports. “Our own packhouse facility in Barasat was looked after by an association of exporters, who shifted to a private packhouse for monopoly business, leaving our facility in a neglected condition. The common exporters have not been allowed to have access to the private packhouse citing paucity of space and thus are being deprived. There is an urgent need for imme-diate revival of our packhouse,” an official of the department said. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedRepresentatives from the West Bengal Agri Horticulture Exporters Welfare Association have held several meetings with the department and Agricultural and Processed Food Products Export Development Authority (APEDA) to address the problem they are facing. “There has been a loss of nearly Rs 50 crore of our association in the last ten months, due to the present situation,” said Bijay Chakraborty, the treasurer of the Association, adding that a section of exporters have already started moving to Assam for exporting to EU. Most importantly, the export of betel leaf (paan) to London has been badly hit. “There are around 5 lakh Bengalis in London and after export of betel leaf was banned by the Bangladesh government three years ago, we have been catering to the demand. However, for the last few months, Salmonella bacteria have been found in abundance on betel leaves and the Union government has denied issuing a quarantine certificate, leading to stalling of export. There is a reasonable demand as the Bengalis in London are not fond of the betel leaves of Sri Lanka and Malaysia,” Chakraborty added. To rub salt on the wound of the exporters, EU has recently come up with more stringent export norms. “They have instructed us to develop backward linkage and good agriculture practice among other things for export. We have taken up the matter with APEDA,” an exporter working closely with the FP&H department said.last_img read more

Mary Austin – The Woman Freddie Mercury Loved and Left Most of

first_imgMary Austin and Freddie Mercury met in 1969 when she was 19, and he was 24. Their life-long relationship proved to be one of a kind. Mary grew up in a struggling working-class household in West London, raised by two deaf parents. She dropped out of school when she was 15 and started working various jobs to support herself.Mary Austin pictured in London in January 1970. Mary Austin would go on to become the girlfriend of Freddie Mercury, lead singer with rock group Queen. Photo by Evening Standard/Hulton Archive/Getty ImagesAt the time the two met, Mary was working in a fashion boutique and Freddie had recently graduated from art college.They quickly fell in love and started living together in a cramped flat. What would become one of the greatest bands, Queen was barely in its beginnings.Queen in New Haven, Connecticut in November 1977 Photo by Carl Lender CC BY-SA 3.0However, Queen’s popularity flourished in 1970, and so did Freddie’s income. During the first few years of the band, while Freddie was experimenting with outrageous clothes and was theatrically strutting, with Mary by his side, nobody questioned his sexuality. In 1973, he dedicated the song Love of My Life to her.Freddie’s mom, Mrs. Bulsara, recalled: “She was lovely and used to come to us for meals. I used to wish they had got married and had a normal life with children.”Freddie Mercury Singing 1977 Photo by Carl Lender CC BY-SA 3.0In a 2013 interview for the Daily Mail, Mary evoked her memories of one Christmas Day when she was 23 and Freddie gave her a big box as a gift:  “Inside was another box, then another and so it went on. It was like one of his playful games. Eventually, I found a lovely jade ring inside the last small box.” She asked Freddie on which hand should she place it and he replied the left.But they never married. Although they were together for seven years, in 1976, Freddie finally confessed his infidelities to Mary, revealing himself as a bisexual, to which she replied: “No Freddie, I don’t think you are bisexual. I think you are gay.”Singer Freddie Mercury of Queen photographed in September 1977 with his girlfriend Mary Austin. Photo by Monitor Picture Library/Photoshot/Getty ImagesThe two separated and Mary moved into a nearby flat, purchased for her by Mercury’s music-publishing company. They ended their physical relationship but remained incredibly close, frequently visiting each other.Freddie once said: “All my lovers asked me why they couldn’t replace Mary, but it’s simply impossible. The only friend I’ve got is Mary, and I don’t want anybody else. To me, she was my common-law wife. To me, it was a marriage…We believe in each other. That’s enough for me. I couldn’t fall in love with a man the same way as I have with Mary.”Posed portrait of Freddie Mercury, Cinzano vest and shorts.

In 1998 she married businessman Nick Holford but the marriage ended in divorce after five years.Although she made her own path, Mary Austin remained part of the band’s extended circle. During the 1980s, she often toured with Queen, working as a secretary for their publishing business.Freddie Mercury backstage at the Live Aid concert at Wembley, July 13, 1985.

Aware of his impending death, Freddie wanted to make sure that Mary would be financially secure.He claimed that he owed her a lot as she stuck by him through thick and thin, and after his death in 1991, in accordance with Freddie’s will, Mary inherited the better part of his wealth – more than $10 million plus his 28-room Georgian palace in Kensington, London. His mother reportedly approved of his decision, stating that Mary was like family to her.The outer walls of Garden Lodge (pictured here in 2014) became a shrine to Mercury following his death in 1991. Photo by Adnergje CC BY SA 3.0Mark Blake, Mercury’s biographer and author of the book Is This the Real Life?: The Untold Story of Freddie Mercury and Queen, says:“She got the house and a share of the publishing. He effectively left a lot to her as if he was leaving it to his widow. Mary was probably good at keeping him grounded. She had been there before the money, before the fame and she was there at the end.”The interior of Freddie’s mansion was made by Mary herself. She designed it for him, choosing the Louis XV furniture. To this day, most of the interior design remains just as Freddie liked it.In the following years, Mary launched a foundation to Mercury’s memory, the Mercury Phoenix Trust, a charity organization that fights HIV and AIDS worldwide.Read another story from us: The rarely told love story of Freddie Mercury & his partner Jim HuttonAged 67, Austin lives a reclusive life behind the high spiked walls of Mercury’s palace, where fans still make regular pilgrimages.last_img read more

The Oldest Advertisement in History Shamelessly Included Awful SelfPromotion

first_imgAdverts dominate the 21st-century landscape. Such is their power that it’s easy to forget there was a time when they weren’t around so much. Look back through history and the first known example of an ad can be found. It’s on a papyrus in the British Museum, London and dates back to Ancient Egypt — specifically, the city of Thebes. Thousands of years old, the material contains what can only be described as a historic case of an employer/employee dispute.Times Square covered with illuminated billboards during the ‘blue hour’ period at dusk, with tourists on the streets.Website tripandtravelblog.com picks up the story, writing “In it, a seller of fabrics called Hapu, claimed he would give a reward (a whole piece of gold) to those who report the whereabouts of the slave Shem and return him to the store.”Things between Hapu and Shem were clearly not harmonious, but the shout out doesn’t end there. In spite of his difficulty, Hapu had his marketing hat on because he added, “where the most beautiful fabrics are woven for each person’s taste.”monumental city of Thebes.Concern for the personal welfare of slaves was far from paramount, so a potential customer could well scroll (so to speak) past the main detail and be attracted by the prospect of a fine weave.Shem’s journey out of servitude isn’t chronicled. He did, however, escape his master, though records show business improved on displaying the innovative papyrus.The era of pyramids and Pharaohs is believed to be where advertising got started. It was far from the disposable ads people see today, with notices reportedly carved in steel. That certainly puts the life of a humble bill poster into sharp relief!Most famous symbols of Egyptian CultureAn alternative for oldest ever advert was offered thanks to Alan D. Eames, who was referred to in a 2017 Listverse article as a “beer anthropologist”. He thought a lusty promotion from ancient Mesopotamia could have topped Shem’s unexpected exit.Eames “found a tablet with the image of an ample-breasted woman holding jugs of the ale. Next to the image, Eames believed the writing said, ‘Drink Elba, the beer with the heart of a lion.’”Tapputi-Belatekallim Mesopotamian tabletThe only thing that stands in the way of this discovery was evidence. Aside from the expert’s description, there’s no hard evidence supporting his claim.Before it suffered a legendary fate, Pompeii was a hotbed of ancient advertising. Politics and propaganda were important early steps in the art of crafting something persuasive.Related Video: Hunger Stone Warnings – Haunting messages on rocks revealed after a drought“The local positions of aedile and duoviri were clearly sought after,” Listverse writes, “because election notices are painted all over the walls of Pompeii.” The job titles relate to magistrate’s positions with responsibility for areas like public maintenance and law and order.Pompeii had its fair share of ads concerning prostitutes and brothels. The proprietors “erected paintings of people in various states of sexual congress so that customers could decide what they wanted from the many services that were offered.”Roman fresco with banquet scene (detail) from the Casa dei Casti Amanti (IX 12, 6-8) in Pompeii.The Romans weren’t prudish, hence notices for “Lupanare (Wolf’s Den)”, a “purpose-built brothel… that contained 10 rooms for guests to use.” Graffiti was also used to spread the word about the best times in town.It wasn’t all salacious. Egos were stroked in ancient Greece, via Classical pottery. The Ancient History Encyclopedia site talks about a particularly insistent kind of artist identification, where a potter (named as Euthymides by Listverse) wasn’t content to merely sign his name.In Britain, outdoor advertising was based on hoardngs (billboards) England 1835, by John Orlando Parry“There was also some rivalry between artists,” the Encyclopedia says, “as indicated by one signed comment on a vase, ‘better than Euphronias could ever have done’.”Read another story from us: Oldest Written Records of the English Language Explained and On DisplayIn current times a man like Euthymides would have taken to social media to get his point across. Options were limited thousands of years ago, though once advertising was established it grew through the centuries to become one of the most powerful forces in human history.last_img read more

The biggest winner in the Raiders move to Vegas is Jerry Jones

first_imgThe biggest winner in the Raiders’ move to Vegas is Jerry JonesThe Raiders’ move to Las Vegas was approved by a 31-1 vote. The Raiders will be stuck in Oakland while the Vegas stadium is built.Jerry Jones was heavily supportive of the move, which now eliminates the possibility that the team could move to San Antonio, which would be bad for Jerra’s business. It also helps out his BFF, Ram’s owner Stan Kroenke, by taking a team out of the California NFL logjam.Jerra is the Frank Underwood of the NFL owner political game, and he came out looking good on the other side of this deal.The 2-3 year lame duck period the Raiders will spend in Oakland could be a disaster. Roger Goodell has to terrified at the prospect of having a competitive Raiders team playing in front of an empty Coliseum in primetime, or potentially hosting home games in the playoffs.“Don’t forget the power of the Dallas Cowboys, and the power of Jerry Jones.This Vegas move is for a lot of reasons. Stan Kroenke didn’t want the Raiders in L.A., and Jerry didn’t want the Raiders in San Antonio. So they end up in Vegas, and suddenly? Gambling? We don’t mind no stinking gambling!“Questions about Coach Cal are legitimateCoach Cal and the Wildcats were on the wrong end of a classic against UNC, and Kentucky exited the tournament prior to the Final Four. A large group of media and Kentucky fans think that it’s unfair to hold Calipari to a higher standard than his contemporaries. Colin disagrees. Kentucky has 3-times the players drafted into the NBA over the last – years than the next closest team.This was a year where the path to the Final Four was easier with many traditional powers either not making the tournament, or falling by the wayside by the Elite 8. The reality is, Calipari and Kentucky are a glamour program. You can’t make that many trips to the NBA Draft Green Room and not have people wondering when you’re going to win your next title.“I think the questions about Calipari are legitimate. He has three to four times the NBA fire power of the star-studded programs, and once again, can’t win a fourth game.”Guests:Kenyon Martin – 15-year NBA veteran joins the show is in-studio to explain why LaVar Ball isn’t helping his kids; how he approaches his own kid’s expectations; and why he is okay with Russell Westbrook shooting a low percentage.Frank Thomas and Pete Rose – MLB greats and Fox MLB hosts are in-studio to discuss their chemistry with A-Rod; how they are handling the A-Rod/J-Lo merger; why it’s hard to defend a World Series title; why Frank thinks championship teams get beat up by the banquet circuit; why Pete used to not pick up a bat from the end of the season until spring training.Albert Breer – Writer for the MMQB joins the show to weigh-in on the vote approving the Raiders move to Vegas; how they’ll handle the lame duck years until the stadium is ready; if Jerry Jones and Stan Kroenke benefit the most from the move; why Vegas is a lock to host a Super Bowl; and if he thinks any other big player moves will get done this week.last_img read more
