Bending light with better precision Explore further (PhysOrg.com) — If typical black paint absorbs about 85% of incoming light, then a newly designed metamaterial that absorbs up to 99% of incoming light may be considered “darker than black.” By taking advantage of the unique light-scattering properties of metamaterials, researchers have discovered that a hyperbolic metamaterial with a corrugated surface can have a very low reflectance, which could make it promising for high-efficiency solar cells, photodetectors, and radar stealth technology.

E. Narimanov, et al. “Darker than black: radiation-absorbing metamaterial.” arXiv:1109.5469v1 [physics.optics]via: Physics arXiv Blog The researchers, E. Narimanov, et al., from Purdue University and Norfolk State University, have posted their study on the radiation-absorbing metamaterial at arXiv.org.In their study, the researchers fabricated a hyperbolic metamaterial out of arrays of silver nanowires grown in alumina membranes. They found that this material absorbed about 80% of incoming light. Then, they ground the surface of the metamaterial to produce corrugations and defects, which they predicted would dramatically reduce the light reflection, increasing the absorption. Their measurements showed that the corrugated metamaterial absorbed up to 99% of incoming light, and that the radiation-absorbing capability is applicable to all parts of the electromagnetic spectrum.As the scientists explained, the metamaterial’s very low reflectivity results from one of its hyperbolic properties: an infinite density of photonic states. This “super singularity” greatly increases the amount of light scattering from surface defects and corrugations in the metamaterial. The defects and corrugations scatter light primarily inside the material, basically “sucking” photons inside the hyperbolic medium.The researchers predict that the new metamaterial will provide a new route toward designing radiation-absorbing materials. As light absorption plays a key role in solar cells and many other applications, the researchers plan to investigate these possibilities in the near future. This document is subject to copyright.

Scientist finds medium sized Kuiper belt object less dense than water

first_img The Kuiper Belt at 20 (Phys.org) —Michael Brown, a planetary scientist with California Institute of Technology, has found a medium sized object in the Kuiper belt (dubbed 2002 UX25) that doesn’t appear to conform to theories of how such objects came to exist. In his paper to be published in Astrophysical Journal Letters, Brown notes that the mid-sized object appears to be less dense than it should be if it followed conventional thinking that suggests the larger the objects are in the belt, the more dense they should get. © 2013 Phys.org Journal information: Astrophysical Journal Letters The Kuiper belt, is of course, a group of rock-like objects (comets, dwarf planets, etc.) orbiting the sun that lie farther out than Neptune. Such Kuiper belt objects (KBOs) are believed to have formed in ways similar to the way planets did, i.e. due to accretion of material over time. Conventional theory suggests that small KBOs are less dense than water because of their porous nature—large KBOs grew more dense as they grew larger due to gravity causing them to compact. If the theory is correct medium size KBOs should have medium density. But this new KBO that Brown has found doesn’t conform to the theory at all, instead, its density is roughly the same as smaller KBOs, suggesting that it’s not size that determines KBO density, but something else. And right now, Brown notes, nobody knows what that something else might be.2002 UX25 has a diameter of roughly 650 kilometers, putting it squarely in the mid-size KBO category, and it, like other KBOs, is believed to exist in very nearly the same state it’s held since the formation of the solar system. It’s in studying such objects that scientists learn more about how everything in our solar system came to be the way it is. Until now, most scientists agreed that KBOs of a size smaller than 350 kilometers across had a density less than that of water, whereas bigger ones had a greater density. That theory might have to be changed however as 2002 UX25 is the first medium sized KBO to have its density measured and it clearly doesn’t conform.The discovery of 2002 UX25’s density properties has already led to new theories, Brown notes, with some suggesting that scientists have been wrong to assume that KBOs and the planets formed at the same time. Instead, they suggest, that it’s possible that KBOs came first and afterwards as the planets were forming, eddies formed causing KBOs to knock into one another breaking them into different sized pieces.

More information: The density of mid-sized Kuiper belt object 2002 UX25 and the formation of the dwarf planets, arXiv:1311.0553 [astro-ph.EP] arxiv.org/abs/1311.0553AbstractThe formation of the largest objects in the Kuiper belt, with measured densities of ~1.5 g cm-3 and higher, from the coagulation of small bodies, with measured densities below 1 g cm-3 is difficult to explain without invoking significant porosity in the smallest objects. If such porosity does occur, measured densities should begin to increase at the size at which significant porosity is no longer supported. Among the asteroids, this transition occurs for diameters larger than ~350 km. In the Kuiper belt, no density measurements have been made between ~350 km and ~850 km, the diameter range where porosities might first begin to drop. Objects in this range could provide key tests of the rock fraction of small Kuiper belt objects. Here we report the orbital characterization, mass, and density determination of the 2002 UX25 system in the Kuiper belt. For this object, with a diameter of ~650 km, we find a density of 0.82+/-0.11 g cm-3, making it the largest solid known object in the solar system with a measured density below that of pure water ice. We argue that the porosity of this object is unlikely to be above ~20%, suggesting a low rock fraction. If the currently measured densities of Kuiper belt objects are a fair representation of the sample as a whole, creating ~1000 km and larger Kuiper belt objects with rock mass fractions of 70% and higher from coagulation of small objects with rock fractions as low as those inferred from 2002 UX25 is difficult.

Researchers look at Oort cloud asteroids

first_img What is the difference between asteroids and comets? Sky & Telescope reports on “A fresh look at a nagging problem—asteroids moving in comet-like orbits” where the research “concludes that asteroids must make up about 4 percent of the vast, distant Oort Cloud of comets.” Four researchers wrote that the usual picture of the Oort cloud as a collection of icy comets in the outer reaches of the solar system is incomplete. “We use simulations of the formation of the Oort cloud to show that ~4% of the small bodies in the Oort cloud should have formed within 2.5 au of the Sun, and hence be ice-free rock-iron bodies. If we assume these Oort cloud asteroids have the same size distribution as their cometary counterparts, the Large Synoptic Survey Telescope should find roughly a dozen Oort cloud asteroids during ten years of operations.” Citation: Researchers look at Oort cloud asteroids (2014, December 9) retrieved 18 August 2019 from https://phys.org/news/2014-12-oort-cloud-asteroids.html More information: Eight billion asteroids in the Oort cloud, Monthly Notices of the Royal Astronomical Society, mnras.oxfordjournals.org/conte … /446/2/2059.abstract . On Arxiv: arxiv.org/abs/1410.7403AbstractThe Oort cloud is usually thought of as a collection of icy comets inhabiting the outer reaches of the Solar system, but this picture is incomplete. We use simulations of the formation of the Oort cloud to show that ∼4 per cent of the small bodies in the Oort cloud should have formed within 2.5 au of the Sun, and hence be ice-free rock-iron bodies. If we assume that these Oort cloud asteroids have the same size distribution as their cometary counterparts, the Large Synoptic Survey Telescope should find roughly a dozen Oort cloud asteroids during 10 years of operations. Measurement of the asteroid fraction within the Oort cloud can serve as an excellent test of the Solar system’s formation and dynamical history. Oort cloud asteroids could be of particular concern as impact hazards as their high mass density, high impact velocity, and low visibility make them both hard to detect and hard to divert or destroy. However, they should be a rare class of object, and we estimate globally catastrophic collisions should only occur about once per billion years. Andrew Shannon, Alan Jackson, Dimitri Veras and Mark Wyatt wrote about their research, “Eight billion asteroids in the Oort cloud.” The authors are from Cambridge, Arizona State University and University of Warwick. To address the question of how common asteroids should be in the Oort cloud, they said they performed simulations of the Oort cloud’s formation, “considering small bodies starting with dynamically cold orbits with semimajor axes from 0.5au to 50 au.” Kelly Beatty, Sky & Telescope senior contributing editor, talked about what the researchers set out to explore. They have taken “a fresh look at what-went-where in the early solar system.” Their computer simulations, accepted for publication in Monthly Notices of the Royal Astronomical Society, confirmed that “lots of rocky bodies originally within 2½ astronomical units of the Sun should be lurking among the Oort Cloud’s half trillion comets.”Shannon and co-authors found that Oort cloud asteroids are a minority, perhaps 4 percent of all the bodies out there, said Beatty. The number may seem small “but that’s still 8 billion objects (eerily matching the Weissman-Levison estimate), totaling perhaps a third of Earth’s mass,” Beatty added.Anything for us to worry about? On the one hand, said the study, Oort cloud asteroids could be of particular concern as impact hazards: their high mass density, high impact velocity, and low visibility make them difficult to detect and to divert or destroy. In the Discussion section of the paper, though, they said that “The rarity of Oort cloud asteroids means that Earth impacts of asteroids from the Oort cloud are quite unlikely to be a threat on human timescales. From our rate estimates, we find they should produce globally catastrophic collisions around once per Gigayear, and locally destructive impacts every million years. Thus although evidence of such occurrences may be found in the geologic record, they are not a pressing concern for the immediate future.”Marcus Woo, writing in Wired, meanwhile, wrote that there’s a thin line, as researchers are learning, between comets and asteroids. “Traditionally, comets and asteroids belong to two distinct categories,” said Woo. “In one corner, you have icy comets with long, wispy tails of gas and dust. In the other, you have dim, rocky asteroids in orbit between Mars and Jupiter.” Some astronomers find the distinction is not so clear, with asteroids found that look like comets and vice versa. They have witnessed discovery after discovery, said planetary scientist Henry Hsieh of Academia Sinica in Taiwan in Woo’s article, blurring the line. Hsieh said astronomers are coming around to the idea that asteroids and comets are at two ends of a range of objects. An artist’s rendering of the Oort cloud and the Kuiper belt (inset).

Researchers build first deployable walking soft robot

first_img More information: Wei Wang et al. “Modular assembly of soft deployable structures and robots.” Materials Horizons. DOI: 10.1039/C6MH00550K The DeployBot can also walk with an ambulating gait, similar to the way a four-legged animal walks. However, this gait requires the robot to support its entire weight on only two legs, and the robot’s legs do not have enough lifting force to do this—at least, not on land. But by placing the robot under water, on the sandy surface of a water tank, the researchers took advantage of Archimedes’ principle which reduces the force required to lift the robot. Currently the robot moves very slowly, at a speed of a little over 2 meters per hour. The robot can also turn, but again at a slow rate, requiring 21 strides to turn 90 degrees. Although the robot is not fast, it could still serve as a useful tool for applications where speed is not important.Going forward, the researchers expect that the techniques used here could also be used to make modules of different shapes, leading to a wider variety of robot designs and functions. The researchers also noted that different methods of moving the robot besides an applied current could be investigated—for example, using pneumatic actuation, magnetic fields, or optical forces. They also suggest that the same approach used here could be used to fabricate microscale and nanoscale structures, which would open up a new range of applications. The researchers expect that the robot’s ability to be easily deployed, along with its low mass, low cost, load-bearing ability, compact size, and ability to be reconfigured into different forms may make it useful for applications such as space missions, seabed exploration, and household objects.The scientists, Wei Wang et al., at Seoul National University and Sungkyunkwan University, have published a paper on the new robot and other types of deployable structures that can be built using the same method in a recent issue of Materials Horizons.”The main advantage of this modular robot is robustness in various environments due to lack of mechanical systems such as motors and gears,” coauthor Sung-Hoon Ahn at Seoul National University told Phys.org. “Thus, problems facing motor-based robots, such as sealing and lubrication of mechanical systems in water or space environments, are not a problem for the smart actuator.”The robot, which the researchers call DeployBot, is assembled from eight modules: four for the body and one for each of the four legs. In their folded state, the modules lie flat, and after they are deployed they pop up into roughly a square shape. The modules are made of both rigid and flexible materials and contain embedded magnets that connect and lock multiple modules together. A shape memory alloy wire running through the square frame of each module is responsible for deploying and folding the modules, which takes several seconds but can be done repeatedly.

The first is an undulating gait, which is similar to the way an inchworm creeps across a surface. To do this, a four-step sequence of current is applied to generate an actuation wave through the robot’s body, from front to back. The imbalance in frictional contact with the ground between the front and back legs causes the robot to pull up its back legs while holding its front legs in place, resulting in forward motion.center_img © 2017 Phys.org This document is subject to copyright.

(Phys.org)—Researchers have built the first robot made of soft, deployable materials that is capable of moving itself without the use of motors or any additional mechanical components. The robot “walks” when an electric current is applied to shape-memory alloy wires embedded in its frame: the current heats the wires, causing the robot’s flexible segments to contract and bend. Sequentially controlling the current to various segments in different ways results in different walking gaits.

Ultraluminous infrared galaxy with strong ionizedgas outflow discovered

first_img With infrared luminosities of over 1 trillion solar luminosities and star formation rates between 100 and 1,000 solar masses per year, ULIRGs are the most intensely star-forming galaxies in the local universe. Hence, finding new galaxies of this type could be important for improving the understanding of star formation and evolution.A team led by Xiaoyang Chen of Tohoku University in Japan is interested in detecting new objects of the ULIRG population. They are constructing a sample of ULIRGs at intermediate redshifts (between 0.5 an 1.0). For this purpose, they have performed an optical follow-up program for far-infrared sources available in the AKARI Far-Infrared Surveyor (FIS) Bright Source catalog by using optical imaging data from the Sloan Digital Sky Survey (SDSS).Their study resulted in the discovery of a new ULIRG at a redshift of approximately 0.5, which received designation AKARI-FIS-V2 J0916248+073034, or J0916a for short. “In this paper we report a discovery of one ULIRG selected from AKARI 90-μm FIR survey, AKARI-FIS-V2 J0916248+073034 (hereafter J0916a),” the researchers wrote in the paper.According to the study, J0916a has a total infrared luminosity of about 6.13 trillion solar luminosities and an estimated star formation rate of nearly 1,000 solar masses per year. The galaxy’s stellar mass was calculated to be around 94.6 billion solar masses.The researchers found that J0916a showcases signatures of an extremely strong outflow in its emission line profiles. They noted that high- and low-ionization potential lines show large velocity dispersions and shifts in relative to the stellar absorption lines. “J0916a shows extreme outflow not only in the [O III] emission line, but also in the [O II] emission line,” the paper reads.The study reveals that the outflow in J0916a most likely extends to a radius of about 13,000 light years. The astronomers say that this outflow is among the most powerful observed in ULIRGs and quasars at redshifts between 0.3 and 1.6, as it has the mass outflow and energy ejection rates estimated to be at a level of around 500 solar masses per year and approximately 400 tredecillion erg/second respectively.Given that J0916a exhibits such strong outflow and an intense star formation process, the authors of the paper assume that the star-forming region of the galaxy has not yet been severely affected by the outflow.In concluding remarks, the researchers suggest further observations of J0916a in order to reveal the properties and origins of the outflow. For instance, they propose spectroscopy observations with higher spatial and spectral resolution to determine the electron density in the outflowing gas, and integral-field spectroscopy to investigate the structure of the outflow.

Warrens On The Rise But Can She Convinc

first_img by NPR News Domenico Montanaro 8.28.19 5:00am Back in April, things looked a little different in the Democratic presidential primary.Elizabeth Warren’s first-quarter fundraising was disappointing; she was eschewing big-money fundraisers, and her campaign was spending a lot — 87 cents of every dollar it was taking in on 160 or so staffers in early states. Setting up a big campaign was starting to look like a high-risk gamble that wasn’t paying off for the Massachusetts senator. She was not polling very well — down around 6%, in fifth place — and struggling to get out of Vermont Sen. Bernie Sanders’ shadow, as they competed for the progressive left.But times have changed. Warren is now surging. She has plugged away with plans, retail campaigning (more than 45,000 selfies so far) and two solid debate performances. As a result, she’s raked in $25 million (still without big-money fundraisers), more than doubled her support (polling consistently second or third nationally) and on Sunday, drew her largest crowd of the campaign yet – 15,000 in Seattle.That even got the attention Monday of President Trump. Rising to his focus is perhaps one of the better weather vanes of who’s doing well in the Democratic primary.Surveys in some crucial early states also show Warren within striking distance — second place in Iowa, behind former Vice President Joe Biden and third in New Hampshire. But questions linger about her long-term chances, following Hillary Clinton’s loss to Donald Trump in 2016. Voters on the campaign trail continue to say they like Warren, but aren’t sure she can win. It’s something researchers and Democratic strategists think she can get past, and they say her rise might already be proving the naysayers wrong already.”She’s so good at explaining her ideas in a way that makes sense to the audience,” said Karen Finney, a Democratic strategist who worked on the Hillary Clinton presidential campaign and Stacey Abrams’ Georgia bid for governor, but is not currently affiliated with any presidential campaign. “And she’s winning people over; the challenge will be all the money that will be spent to make her ideas sound scary.”Debbie Walsh, director of the Center for Women and Politics at Rutgers University, said the questions about Warren’s electability are something of a self-fulfilling prophecy.”In some ways, it seems like it’s a story that is self-perpetuating,” Walsh said. “There are a lot of people who say they’re enthusiastic about her, but afraid others aren’t — and that creates this notion that she or a woman in general won’t become electable.”Explaining Warren’s riseThere’s evidence that Democratic voters are warming up to Warren. The more they see her, the more they seem to like her. Warren has now leapfrogged Biden and Sanders as the candidate with the top net-favorability rating.An average of national polls in the month of August found 68% of Democratic voters said they had a favorable opinion of her, while just 15% had an unfavorable one, for a net difference of 54 points. For Biden, it’s a net of 52 points (73% favorable, 21% unfavorable). Sanders comes in at a net of 51 points (72% favorable, 20 percent unfavorable). Harris is next with a 40-point net rating (60% favorable, 20% unfavorable).What’s more, since May, Warren has gotten more popular while Biden has gotten slightly less popular, and Sanders is about where he’s been. More Democrats have an opinion of Biden and Sanders than they do of Warren, meaning Warren has some room to grow.Democratic polling has also found Warren is Democratic voters’ “magic-wand choice,” according to a survey from Avalanche Strategy. In other words, she may not be leading in the polls, but she’s the one more Democrats want to actually be president if they could pick someone.Biden led in the “horse-race choice” with 29%, Sanders was second with 17%, and Warren was third with 16%. But when it came to asking them who they would make president with a “magic wand,” Biden dropped 10 points to 19%, and Warren jumped 5 points to 21%.The poll was conducted before the first rounds of debates, and Democratic voters gave Warren top marks for her performance in them.The poll, however, also found some doubt among Democratic voters – almost 90% said it was “extremely important” to beat President Trump. But their confidence that a Democrat would win was a different story. Less than a third said they believed the likely Democratic nominee would “certainly” win. Republicans, on the other hand, were far more locked in believing President Trump will win reelection – 61% said Trump would “certainly” win.What explains this gap? Largely gender.The poll asked respondents what their “magic wand” candidate could do to make them more electable. The researchers “looked specifically for mentions of many qualities frequently discussed as potentially driving electability including ideology, age, race, sexual orientation, and gender. … Gender is mentioned the most of any factor.” And get this: “Among the respondents who mention gender, 69% are female.”Some of the respondents said things like:”I’m not sure a woman can beat Trump. Honestly the misogyny and racism in this country right now is heartbreaking. I hope one day she’s president though. She is amazing,” said a 39-year-old female from Kentucky.”I don’t know, I don’t think men will vote for her or any woman,” said a 75-year-old female from North Carolina.Part of Warren’s challenge — and opportunity — is to convince women that she is electable. Women have been a driving force behind the “resistance” to President Trump, they were the fuel to taking back the House in the 2018 midterm elections, and they make up a strong majority of Democratic voters. In the 2016 primary, for example, women made up 58% of Democratic primary voters and caucusgoers, according to exit polls.It’s a similar potential path for President Obama’s victory over Clinton in the 2008 primary. Key to his win was convincing African Americans that white voters would back him. After winning the Iowa caucuses, which were more than 90% white, Obama took off with black voters, leading to his crucial victory in South Carolina.Michiah Prull, CEO of Avalanche Strategy and the former field director of Barack Obama’s Florida campaign in 2012, points out that Warren seems to be starting to convince Democrats that she can win.”Her rise is very likely due to an increased belief that she is viable,” Prull said. “It really is that perception of other people’s perception. It’s a concern that other people would not support a female candidate. If we see Warren really rising, that likely indicates a shift in how people are perceiving how electable she is.”The Hillary Clinton factorA lot of the trepidation about whether Warren can win stems from the results of the 2016 election, where Hillary Clinton lost to President Trump, despite winning 3 million more votes. That’s something, Walsh said, is short-sighted.”It’s this idea that women are risky because one woman lost her election for president of the United States,” Walsh said, “and yet we’re looking back at an election like 2018, where Democrats did pretty well by having women candidates. They had a pretty good return on investment — women were responsible for flipping the house from red to blue.”Finney also points out that Clinton’s run, as the first woman to be a major-party nominee, may have actually helped lay the groundwork that would help a woman win the White House in the future. “There’s something different about being the second, not the first,” Finney said. “As the first to run and win the nomination, Hillary bore a lot of the brunt of and showed it was possible.”Walsh agrees, noting, that if Warren were to win the nomination, she would “have the benefit of having a woman run before. Hillary Clinton did not.”But, above all, Warren just isn’t Clinton. “At the beginning,” Walsh said of Warren, “there was this narrative of her being ‘school marm,’ and that’s faded, because she comes bounding out, in this just enthusiastic, whatever-your-problem-I’ve-got-a-plan-for-that way. Enthusiasm exudes from her.”Clinton, on the other hand, “had built more of a protective barrier between herself and the public — and some of that is totally understandable,” Walsh noted, given attacks over decades from the right. But “there was a cautiousness about her that you don’t necessarily feel with Elizabeth Warren.”There are still lots of questions about Warren’s candidacy – in particular, how will she handle the inevitable scrutiny – from all sides — that comes with a rise in the polls? But Walsh thinks Democrats should focus on different “e” word over electability – enthusiasm.”There is this panic mode on the Democratic side to do whatever it takes to win the election,” she said. “But I don’t know if at the end of the day, someone lukewarm does it and gets someone to turn out at the polls.”Copyright 2019 NPR.

Man thrashed for failing to answer queries on PM national anthem

first_imgMalda: A man was allegedly assaulted by four persons in a moving train in West Bengal, after he failed to reply to their queries on the prime minister and the national anthem, police said on Friday. The victim,, a migrant labourer, was on his way to Kaliachak in Malda district from Howrah on May 14, when the four persons got into the train and sat next to his seat after he had briefly deboarded at a station, a police officer said.Upon his arrival, they suddenly started asking him questions about Prime Minister Narendra Modi, the national anthem and Chief Minister Mamata Banerjee, he said, adding, the man was roughed up when he could not reply to the queries.The group later got down at Bandel station.A local NGO – Bangla Sankriti Mancha – lodged an FIR yesterday against the accused, based on videos taken by co-passengers, Kaliachak Police Station Inspector-in-Charge Suman Chatterjee said.An investigation into the matter is underway, Chatterjee said.last_img read more

That is well known to everyone,” he told reporters outside Parliament. The minister said he could not say about the clarification to be given by the government in Parliament but requested everyone not to misconstrue a statement which is based on specific questions.  Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJI “So, if necessary, clarifications will be given but what I want to say is that please don’t question the intention of the government, the government is very clear and government’s job is well defined and it is pursuing the case very seriously,” he said.Earlier, replying to a written question of BJP MP Nityanand Rai in the Lok Sabha, Minister of State for Home Haribhai Parathibhai Chaudhary said, “The subject has not been located so far. Extradition process with regard to Dawood Ibrahim would be initiated once the subject is located.”  Interestingly, the government has been maintaining for a long time that Dawood is living in Pakistan with the patronage of Pakistani security establishment.The name of Dawood, who is wanted in connection with 1993 Mumbai serial blasts, figures in almost all the dossiers that have been handed over to Pakistan since the NDA rule in early 2000.last_img read more

Ayushmann wants to playback for SRK

The voice will match because I mimic him pretty well, so I can sing like him. It will be quite credible,” said Ayushmann.

Be careful before getting a tattoo or piercing

first_imgWhile tattoos and body piercings are an increasingly popular form of self-expression. It is important for young people to carefully weigh the consequences and potential risks associated with such body modifications, suggests a clinical report by the American Academy of Paediatrics (AAP). “In most cases, teens just enjoy the look of the tattoo or piercing, but we do advise them to talk any decision over with their parents or another adult first,” said David Levine, co-author and professor at Morehouse School of Medicine in Georgia, US.”They may not realise how expensive it is to remove a tattoo, or how a piercing on your tongue might result in a chipped tooth,” Levine added, in the recommendations published in the journal Paediatrics.The recommendations stated that while societal acceptance of tattoos and piercings has increased, there may still be repercussions. This includes losing out on job opportunity as well as suffering infections. Further, before getting a tattoo or piercing, one should make sure that the salon is sterile, clean and reputable. The facility should also be regulated by the government and should provide clients with information on how to care for the area that has been tattooed or pierced afterward, the researchers emphasised. “Reputable tattoo parlours and piercing salons should provide a long list of dos and don’ts on how to care for the area that was worked on, and what signs might indicate a problem,” said lead author Cora C. Breuner, chair of the AAP Committee on Adolescence. Moreover, someone considering a tattoo should make sure that their immunisations are up to date and that they are not taking any medication that compromises their immunity in any caondition, the report said.last_img read more

New year resolution Whats on millennials list

first_imgWith new year comes new hopes, commitments, immense excitement, a million new opportunities, and the ‘traditional declaration of things we resolve to do’. We start with promises like ‘I will lose weight this year’, ‘I will make complete use of my time’, ‘I will lead a healthy life’, ‘I will be more punctual’ but end up crashing on the couch, eating french fries while watching our favourite web series on Netflix. Writing a long list of things we should be doing to become a better version of ourselves is custom, and carrying over the list to next year is our habit because we have taken the saying ‘Resolutions are meant to be broken’ way too seriously. Also Read – Add new books to your shelfWhile talking about their new year plans, millennials gave us a sneak peek into the resolutions they make every year, but miserably fail to fulfill the commitment. Soyeb Allam: Now that time has come to bid adieu to 2018, sensational discourses on new year resolutions are quite routine. Upraised adrenaline rush it may seem yet getting in shape by shedding off some extra fat will be my very first one (Cliched of course!) A steady and gradual learning curve at workplace will be second. Shopping more from local vendors than from malls will be my third. I have zillions more on the list, but it would take another year to see how many of these I actually manage to tick off. Also Read – Over 2 hours screen time daily will make your kids impulsive Rubab Hassan: So happiness is vastly underrated. This year I resolve to see positives in every challenge life has to offer and find happiness in whatever comes my way. Yuman Khan: The resolution which I fail to keep like always is that I will work for myself and the betterment of me without getting involved emotionally in relationships which I believe can defy me someday. And this year, once again I will try to work towards it. Samra Raza: Everyone jumps on the same bandwagon, make a long list of resolutions, and throw the entire list in the dustbin. But this year, I have decided to keep it short and specific. First of all, I will vote in the upcoming election for real ‘Acche Din’. Second, I will do at least three things I always wanted to, for example visiting some good historical place. And lastly, I will stick to a healthy lifestyle as I am turning 22 this year. Areeb Uddin: Every year, I aim to achieve certain goals, one of which is to lose weight. But unlike previous years, this time I will work harder to accomplish it and that too without losing money. Shamaila Khan: My new resolution is to remove all the negativity from my life, get rid of toxic people and lead a peaceful life. I also need to complete my bucket list which has been pending for too long now. I will read more, be a good listner, talk less and act more maturely. Gaurav Badiyani: This year, I have decided to stop procrastinating, quantise my goals and work to achieve them. Secondly, I will work to attenuate all my bad habits. And surely, I will stop my inner geek from playing PUBG this year. Vipul Sipani: Like every year, I set a goal of making good amount of money but always ends up with zero savings. This year my resolution is to work more and save some money by the end of 2019. Also, I will work on my physique and try to get in good shape. Anveshi Jain: This year is a harbinger of many firsts of my long cherished dreams. My immediate resolution is to get into the best shape of my life. I intend to push and focus on my acting career, after the wonderful platform and opportunity I have got with my presence in a super successful web series. I aim to be stronger, more focused, bolder and more resolute in my choices, aspirations, and ambitions. All this, and of course an unabashed thrust to stay happy and full of life. Heena Kapoor: Being in the business of Public Relations, I try to train new students with all the little experience and knowledge that I have. A few years back, it was extremely difficult for somebody like me to create a niche in the industry, but I don’t want others to go through the same journey as mine. This year too, I plan to do the same. Dhairya ramchandani: I will try to improve my sleep patterns, so as to start my day early on time. The basic idea is to be more punctual from this year. Also, I will try not to be lazy in preparing letters and doing paperwork (related to business), as that is the part of work I try to run away from most of the time. Deepak Malik: Every year I make a resolution to prioritise myself but end up failing badly. I will not beg anyone to stay only to put my self-respect on stake miserably at the end. Also, this time I have made a resolution to be the happiest version of me and not let anyone make me feel bad about myself or doubt my self-worth. Almas Raza: Like always, I have made a long list of resolutions. The first and the foremost for me is to be a good listener. Then, I will work to increase my patience level. Thirdly, I will not allow anybody to control me emotionally. And lastly, I will live every moment of this year focussing only on those people, who truly love me.last_img read more

Higher salt intake leads to bloating

first_imgPeople report more gastrointestinal bloating when they eat a diet high in salt, a study has found. Researchers at the Johns Hopkins Bloomberg School of Public Health in the US re-analysed data from a large clinical trial conducted two decades ago, and found that high sodium intake increased bloating among trial participants. “Bloating is one of the leading gastrointestinal complaints in the US and can be exacerbated in some people by a high-fiber diet. Our results suggest that they might be able to reduce that bloating, without compromising on healthy fiber, by lowering their sodium intake,” said Noel Mueller, senior author of the study. Also Read – Add new books to your shelfBloating is estimated to affect up to a third of US adults overall, and more than 90 per cent of those with irritable bowel syndrome, according to the study. Bloating features a buildup of excess gas in the gut. The production of gas can be attributed to gas-producing gut bacteria breaking down fiber. There is also some evidence that sodium can stimulate bloating. The study analysed data from the DASH-Sodium trial, conducted at four clinical centres during 1998-99. It tested the DASH diet, a high-fiber diet which is relatively low in fat and high in fruits, nuts, and vegetables, against a low-fiber control diet. Also Read – Over 2 hours screen time daily will make your kids impulsiveEach of the two diets was tested at three levels of sodium, and the 412 participants all had high blood pressure at the trial start. The trial was set up chiefly to determine the effect of dietary sodium and other factors on blood pressure, but included data on participants’ reports of bloating — data that Mueller and his colleagues analysed for the new study. The team found that prior to the trial, 36.7 per cent of the participants reported bloating, which is more or less in line with national surveys of bloating prevalence. They found too that the high-fiber DASH diet increased the risk of bloating by about 41 percent, compared to the low-fiber control diet – and men were more susceptible to this effect, compared to women. But the scientists also determined that sodium was a factor in bloating. When they combined data from the DASH and control diets, and compared the highest level of sodium intake to the lowest, they found that the high-sodium versions of those diets collectively increased the risk of bloating by about 27 per cent compared to the low-sodium versions.last_img read more

4 of the Most Fascinating Maritime Mysteries

first_imgThe Baltic Sea AnomalyIn 2011, a group of divers who were exploring the floor of the Baltic Sea with sonar stumbled across an object measuring 70-meter long (210 feet) laying 100 metres (300 feet) beneath the waves. The object, dubbed the Baltic Sea Anomaly, has sparked international interest due to its intriguing shape and location. The anomaly appears to have been handcrafted and made of metal and has an uncanny resemblance to the Millennium Falcon from Star Wars, leading many conspiracy theories about its origin. Some have suggested that the anomaly is a UFO while others have suggested that it is a formation from a sunken city, buried beneath the waves.The Baltic Sea Anomaly (YouTube)In 2017, a team from Stockholm university studied the anomaly and found that it is a glacial formation deposit, probably left over from the Ice Age. As Volker Brüchert, an associate professor of geology at Stockholm University, discusses with the Express, “Because the whole northern Baltic region is so heavily influenced by glacial thawing processes, both the feature and the rock samples are likely to have formed in connection with glacial and postglacial processes.”Mary CelesteMary Celeste in 1861On December 5th, 1872 the Mary Celeste was discovered floating adrift on choppy seas. The ship had left New York City for Genoa, Italy on the 7th November 1872 with a cargo of industrial alcohol and a ten-man crew but when the rescue party boarded, they were surprised to find the crew had vanished, leaving behind their cargo, their possessions and a fully stocked food parlor.The young Arthur Conan Doyle, whose 1884 short story did much to disseminate Mary Celeste mythsThe ship’s lifeboat was missing, and one of the two pumps was disassembled, and there was three and a half feet of water in the hold. The crew were never seen again, and the mystery has remained unsolved for 300 years.A waterspout, photographed off Florida (1969). A waterspout strike has been offered as a possible solution to the Mary Celeste mystery.Theories range from the ridiculous to the scholarly, the most implausible being giant sea monsters and the more believable being that bad weather (possibly a waterspout) and faulty equipment led the captain to miscalculate that the ship was sinking so ordered the crew to abandon ship.The Sunken City of Pavlopetri – the Real Atlantis?Overview of Pavlopetri. Photo by Spiridon Ion Cepleanu CC BY SA 3.0The site has been dubbed the oldest sunken city in the world and dates to around 5,000 years ago. It is the oldest submerged site that has been found to be a planned city with buildings, courtyards, main streets, rock-cut tombs, and religious structures, showing that the city was used by the elites of the time.Pavlopetri Photo by Spiridon Ion Cepleanu CC BY SA 3.0It is the first sunken city to be found that predates Plato’s story of Atlantis and may have been the inspiration for it. Marine geologists speculate that the city was sunken by a combination of sea level changes, changes in ground subsistence and a tsunami.Where is the Patanela? Australia’s Enduring Maritime MysteryMessage in a bottle resting on shore during sunsetWhen the Patanela left from Fremantle, Australia on October 16, 1988 nobody on board thought this would be their last voyage. About three weeks into their journey from Fremantle to Airlie Beach, Queensland the Patanela made a series of calls to Sydney harbor shore station.The first call indicated that the Patanela had run out of petrol and would need bringing into harbor the next day; the second call was for a weather report then, strangely, in the same call, the skipper asked for directions to Moruya in New South Wales; the third call was heavy with static, and all that could be made out was the sentence “Three hundred kilometers south? Is it south? Is it? South…” This was the last time anyone heard from the Patanela and its four-person crew.Seven months later a barnacle-covered bouy from the schooner was found and then in 2008 when a message in a bottle was found and inside was a 1988 invitation to join the crew for a free trip to the Whitsunday Islands and a phone number to call.Read another story from us: 4 of the World’s Lost Underwater CitiesMany speculate that the Patanela was a victim of piracy or drug runners while others think it was hit by a bigger boat and left to sink. There is no evidence to support either theory, and the mystery continues to this day.last_img read more

Gene Tierneys Unfortunate Life was the Inspiration for an Agatha Christie Novel

first_imgDarryl F. Zanuck, the founder of 20th Century Fox, had some of Hollywood’s most beautiful actresses under contract —  among them, Betty Grable and Marilyn Monroe. But the woman that the mogul would describe as “the most beautiful in movie history” was Gene Tierney.This wasn’t the usual Hollywood hyperbole: the green-eyed beauty, with the impossibly chiseled cheekbones, was breathtaking.Promotional photograph of actress Gene Tierney, early 1940s.Tierney had the talent to go with that gorgeous face, and was a top box office draw during the 1940s, starring in such films as Leave Her to Heaven, The Razor’s Edge, Laura, and The Ghost and Mrs. Muir.Gene Tierney in the Laura trailerTierney’s off-screen life rivaled any of her film roles when it came to sheer drama. Indeed, a chance meeting with a total stranger would set off a catastrophic chain of events with far-reaching consequences.Pin-up photo in World War II magazine Brief.Tierney, married to legendary designer Oleg Cassini, contracted rubella during a World War II USO appearance at the Hollywood Canteen, allegedly because a female marine with the illness snuck out of quarantine to meet her favorite star.Gene Tierney in Yank Army WeeklyAs a result, in October 1943, Tierney would give birth prematurely to a daughter, Daria. The rubella caused congenital damage, leaving the baby, who weighed just over three pounds at birth, partially blind, deaf, and mentally disabled.Oleg Cassini, 1962.Reportedly, Tierney would learn what led to her child’s devastating illness years later when she and the fan crossed paths again, with the young woman reminding her idol about their previous meeting — confessing that she had been sick when they met.Gene Tierney in the Ghost and Mrs. Muir trailerSound familiar? If you’re an Agatha Christie fan, it just might. The tragic tale was the inspiration for the mystery writer’s 1962 book The Mirror Crack’d, adapted for the big screen in 1980, with Elizabeth Taylor playing the role based on Tierney’s life.Agatha Christie’s novel The Mirror Crack’d was based on Tierney’s real-life tragedy.The ending of the Christie novel would offer a different ending. (Upon learning the ugly truth, Taylor’s horrified character — like Tierney, an actress — slips poison into the fan’s cocktail.) But the real-life story is no less dramatic…or devastating.The tragedy would haunt Gene Tierney for the remainder of her life. She and Cassini separated in 1946; however they reconciled before the divorce was due to finalize in 1948 and had a second daughter, Tina. In time, Tierney started having trouble concentrating, which impacted her acting career.Gene Tierney, Yank magazine pin-up.Tierney was slated to star in the romantic adventure Mogambo, opposite Clark Gable, but left the production and was replaced by Grace Kelly.Two years later, starring opposite Humphrey Bogart in The Left Hand of God, Tierney would fall ill once again.Humphrey Bogart supported his co-star during the filming of The Left Hand of God and encouraged her to seek professional help.Her leading man showed his soft side, feeding her lines to help her get through the production. One possible reason for Bogie’s empathy: One of his younger sisters also grappled with mental illness.Tierney began seeing a psychiatrist and entered the Harkness Pavilion in New York, and later, the Institute of Living in Hartford, Connecticut. She would undergo twenty-seven electroshock treatments, in an effort to treat her severe depression. (Years later, Tierney would speak out against shock treatment therapy, saying it had erased portions of her memory.)Tierney later returned to acting, with smaller roles in movies and television. Her last feature film was 1964’s The Pleasure Seekers, a bit of comedic froth, and her final appearance was in the 1980 miniseries Scruples, based on the Judith Krantz potboiler. Tierney died of emphysema in Houston, in 1991, shortly before her 71st birthday.Read another story from us: The mysterious disappearance of Agatha Christie for 11 daysBoth of her daughters, Daria and Christina, passed away at age 66. Tierney’s friend Howard Hughes, it’s said, paid for Daria’s medical expenses till the day she died — a kind gesture that would never be forgotten by the actress.last_img read more

Rare Blue Pigment Found in Medieval Womans Teeth has Historians Excited

first_imgTeeth reveal all manner of things about our health, and it’s no surprise that archaeologists often rely on evidence from teeth and bones in order to draw conclusions about the lives of our ancestors. However, the discovery of a blue-stained tooth in the corpse of a medieval nun has left historians particularly excited about the possible implications.An interdisciplinary team of archaeologists, anthropologists, historians and scientists recently published a groundbreaking study in which they report that bright blue deposits were found in the teeth of a medieval nun at a monastery in Dalheim, Germany.Photo Courtesy Christina WarinnerAccording to the report, published in the journal Science Advances, this particular woman had an astonishing number of ultramarine flecks in her mouth, which appeared to have accumulated over many years.Further analysis revealed that the blue flecks were actually lapis lazuli, a rare and vibrant blue pigment found only in an area of Afghanistan.This rare and expensive material was used in the production of lavishly decorated manuscripts, and was reserved for only the most important texts.Photo by John Moore/Getty ImagesBlue is a notoriously difficult color to manufacture, and the brilliant, bright hue created by lapis lazuli was in high demand for exceptional works of art.Lapis lazuli was imported from Afghanistan, ground into a powder and mixed with water to make a pigment, which was then carefully applied to illustrated manuscripts by trained scribes.Only the most accomplished and experienced scribes would be trusted to handle such a rare substance; it was at least as expensive as gold and much more difficult to find.Lapis lazuli block. Photo by Luna04 CC BY-SA 3.0According to the report in Science Advances, the team found that the teeth contained many flecks of lapis lazuli that had become embedded in the dental calculus, hardened plaque that gathers on the teeth over the course of a lifetime.Furthermore, the pattern of these deposits was consistent with a licking motion, as if they had accumulated when the scribe licked the end of her brush with her tongue.Analysis of the corpse indicated that this particular scribe was female, and aged between 45 and 60 years old when she died. Aside from the extraordinary amount of lapis lazuli they found in her mouth, the team agreed that she was an otherwise normal and healthy woman.Radiocarbon dating techniques revealed that she was alive sometime between 997 and 1162, during a period in which European monasteries were flourishing.Monasteries were a hotbed of artistic activity in medieval Europe, and all kinds of religious, liturgical and historical texts were produced in these institutions.Dalheim Church of St. Peter and women’s monastery. Photo Courtesy C. Warriner et al., 2019/Science AdvanceManuscript illustration is one of the most elaborate and beautiful forms of medieval art, and these objects represent labors of love created by skilled scribes trained in the religious community.It has often been assumed that the majority of scribes who produced these beautiful works of art would have been men. Some historians have even gone so far as to suggest that women would have been prohibited from illustrating important manuscripts in this period.Photo Courtesy C. Warinner (A); M. Tromp and A. Radini (B to I).More recently, however, important work by historians such as Alison Beach has shown that female scribes were much more prevalent in European monasteries than has previously been assumed.Part of the difficulty in identifying female scribes is due to the fact that the majority of medieval texts were produced anonymously, and even those that were signed rarely include a female name.As a result, this discovery marks an important breakthrough. It provides concrete evidence that women were involved in the production of some of the most important manuscripts produced in religious foundations, as lapis lazuli would have been reserved for only the most special texts.Photo Courtesy A. Radini, E. Tong, R. Kröger.It also may point to the significance of the monastery at Dalheim as a center of manuscript production. Prior to this research, very little was known about the monastery and what went on within its walls.The study is also important in showing the movement of exotic goods on long distance trade routes from Asia, and the ways in which they were used in Western European societies.This supplements recent research that attests to the connections that existed between Europe, the Middle East and Central Asia in the medieval period, and emphasizes the vitality of medieval trading routes.Read another story from us: Incredible Forest ‘Crop Circles’ Appear in JapanThe members of the team are particularly hopeful about the possibility of applying the techniques developed in this study to other contexts.
