When a hyperbolic metamaterial is corrugated, its reflectance is greatly reduced and it becomes “darker than black.” Image credit: E. E. Narimanov, et al. 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.

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.

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).

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. © 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.

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.

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.

Malda: 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.
After the government was left red- faced over its contradictory reply in Parliament on the whereabouts of Dawood Ibrahim, junior Indian Home Minister Kiren Rijiju said the underworld don lives in Pakistan and the Centre would continue to pursue the case very seriously.“Government’s consistent stand is that he (Dawood) is in Pakistan and government of India has been providing information to Pakistan about his whereabouts and Pakistani agencies are not cooperating with Indian government. 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.

He may have crooned several hit songs for himself, but actor-singer Ayushmann Khurrana says if given a chance he would love to do playback singing for superstar Shah Rukh Khan.Ayushmann, 31, who has sung many popular tracks like Paani Da Rang and Saadi Galli Aaja, feels his voice will match with that of the Chennai Express actor, as he imitates him well.“I don’t know, I would probably love to do playback for Shah Rukh. The voice will match because I mimic him pretty well, so I can sing like him. It will be quite credible,” said Ayushmann.
