Four years later, it yielded some intriguing data: An unusually high number of gamma-ray photons from the galactic center carried the same energy—a particular, significant energy—and nobody could figure out why. The energy is 511 keV (kilo electron volts), and it happens to be the exact rest-mass energy of the positron, the electron anti-particle, which emits a 511 keV photon when it annihilates with an electron. The gamma rays, then, are a telltale sign of positrons in the galactic center. Where those positrons come from, however, is not so clear.At one point, scientists thought the positrons might originate as electron-positron pairs often referred to as positronium, an “element” that exists for a very short time before the electron and positron annihilate. For positronium to be the source of the gamma rays, there would have to be lots of it, but the usual positron sources, such as black holes and supernovae, don’t emit enough of them.”Theorists have thought that the 511 keV line might be from dark matter annihilation located at the center of our galaxy, but all the well known standard dark-matter candidates, such as the lightest super-particle, could not fit the data,” said astrophysicist Seong Chan Park to PhysOrg.com.Park and colleagues Ji-Haeng Huh, Jihn E. Kim, and Jong-Chul Park are researchers at Seoul National University in Korea, and the group recently proposed an explanation that involves a new particle.The group suggests that the positrons come from a “millicharged fermion,” a very lightweight particle with a tiny electric charge. The suggestion isn’t groundbreaking, as many physicists think that there may be some new physics—a new particle, specifically—underlying the gamma-ray production.”Most preferred interpretations of the 511 keV gamma rays involve the introduction of new particles, and a millicharged fermion has been proposed before, as far back as 20 years ago, as a dark-matter candidate.” said Park. “But in this work we have handled the urgent problem of interpreting the 511 keV anomaly using millicharge fermions, within certain physical constraints.”The proposed particle can produce positrons, which would emit 511 keV gamma-ray photons by decaying into positrons and electrons, which would annihilate and emit the photons. Alternatively, it could annihilate with its own antiparticle to yield an electron and positron that would then annihilate.The millicharged fermion, if it exists, would have escaped detection at collider experiments because its electric charge is so minute, say Park and his colleagues. They also suggest the particle as a dark-matter candidate, possibly making up 10 percent of the dark matter in the universe.”In the beginning, we worried if the idea of ‘millicharged’ dark matter might be inconsistent with any existing experimental data,” says Park. “As it turns out, that it is not the case and there is room to fit all of them, which is interesting.”This research is described in the June 3, 2008, online edition of Physical Review D.Citation: Phys.

© 2010 PhysOrg.com (PhysOrg.com) — How many of you remember the film The Expendables? It was an action flick, featuring some of the biggest names in blowing things up, and soon it will be known as the film that has created the largest illegal-BitTorrent-downloading case in U.S. history. Stolen ‘X-Men’ flick leaps onto Internet A federal judge recently gave the U.S. Copyright Group the right to subpoena the records of Internet service providers in order to see who downloaded the movie illegally. So, while 23,000 is the current expected number of defendants that number may increase by leaps and bounds as more downloads are found. When an ISP gets a subpoena they will generally tell the account holder that their subscriber information is being shared with the Copyright Group, pursuant to their investigations. So, if you are part of this suit, you will likely find out sooner rather than later. This is not the Copyright Groups only attempt to take legal action against bit torrents. One the whole, this group is taking legal action against roughly 140,000 BitTorrent downloaders, primarily for downloading B-movies and pornography. Eventually, these kinds of suits will become a bigger revenue stream than the films sales themselves. Under the current U.S. copyright law damages of up to $150,000 per infringement can be obtained. For a film that only grossed $103,068,524 domestic, if this level of damages were paid, the dollar figure would well out pace film sales. With subpoenas are expected to go out this week, one has to wonder if this is not a good time to not only forget about the bit torrenting, but also about feature films altogether. After all, if these users had wanted the film that badly, they could have bought it for roughly $20 or rented it for $6, and none of them chose to do so. That may speak to the quality of the film, as much as the ethics of the fans. Image credit: Chaaps Explore further This document is subject to copyright.

Binary asteroids are not wholly uncommon – space scientists estimate that as many as 15 percent of those observable are binaries. This observation has caused scientists problems though, due to the dearth of evidence of binaries striking the Earth – as few as 2 to 4 percent. In this new research, the team, led by Katarina Miljkovic, suggests that many of the craters evident on the surface of the Earth, and believed to have been caused by a single asteroid, may in fact have been caused by binaries. They say that a binary could cause just one crater if the two asteroids were close enough together when they struck. They suggest such craters would likely have a peanut shape, or have one side distorted.The team came to these conclusions after building computer simulations that showed asteroids hitting the earth. Some of the craters that resulted were oblong, or irregularly shaped, which they say, means the same could be true of real craters here on Earth. They point to Chicxulub as one such example, which many scientists believe is the scar left behind by an asteroid strike so violent it caused the demise of the dinosaurs. They note that the crater has some asymmetries that could be explained by a binary strike. If that were the case, they further suggest it likely that the combined size of the asteroid would have been roughly the same as the calculated size of a single entity – namely a combined diameter of 7 to 10 km. The crater left behind has a diameter of approximately 180 km, which means, the researchers say, that twin asteroids could have been as far apart as 80 km and still produced a single crater.The researchers suggest scientists will have to take a new look at other existing craters to try to determine if they too are possibly the result of binary strikes and if so, recalculate their number. Likewise, other scientists might also begin to ponder the doubly hard problem of preventing future binaries from striking the planet. Journal information: Earth and Planetary Science Letters Example of overlapping craters most likely created in close binary asteroid impacts: (a–b) elliptical, (c) peanut shaped, (d) tear-drop shaped and (e–f) elliptical with a lip, identified using THEMIS database (Christensen et al., 2010). The white outline shows the transverse ejecta lobes formed in a collision of the ejecta from the two close craters forming simultaneously.

However, the observed number of plausible doublet craters is 2–4% on Earth and 2–3% on Mars. This discrepancy between the percentage of binary asteroids and doublets on Earth and Mars may imply that not all binary systems form a clearly distinguishable doublet crater owing to insufficient separation between the binary components at the point of impact. We simulate the crater morphology formed in close binary asteroid impacts in a planetary environment and the range of possible crater morphologies includes: single (circular or elliptical) craters, overlapping (tear-drop or peanut shaped) craters, as well as clearly distinct, doublet craters. While the majority of binary asteroids impacting Earth or Mars should form a single, circular crater, about one in four are expected to form elongated or overlapping impact craters and one in six are expected to be doublets. This implies that doublets are formed in approximately 2% of all asteroid impacts on Earth and that elongated or overlapping binary impact craters are under-represented in the terrestrial crater record. The classification of a complete range of binary asteroid impact crater structures provides a template for binary asteroid impact crater morphologies, which can help in identifying planetary surface features observed by remote sensing. (Phys.org)—A team of researchers from the U.K. and Australia has published a paper in the journal Earth and Planetary Science Letters, suggesting that the crater Chicxulub, off the coast of Mexico, may have come about due to the impact of binary asteroids (those that travel in pairs), rather than just a single one. The crater is thought by many scientists to be evidence of an asteroid strike that led to the extinction of the dinosaurs. This document is subject to copyright.

He has done it in just 4.22 seconds. The achievement was recorded at an event held in Melbourne called Cube for Cambodia. Don’t blink now: Robot does speed cube puzzle solution in 0.38 seconds © 2018 Phys.org The Rubik’s cube was created in 1974 by a Hungarian man named Ernő Rubik, and it gained international notoriety in 1980 when it was licensed and produced by the Ideal Toy Corporation. It has since become one of the most well-known toys and puzzles in the world. The 3x3x3 cube has stickers affixed to each face of a given color. Initially, the faces of each side of the cube are all the same color. Twisting and turning the cube jumbles the colors in a random assortment. Solving the puzzle involves restoring each face to a single color.Despite his young age, Zemdegs has been working with the Rubik’s Cube for some time. He has told the media that he got his first one at age 12, just a decade ago. He claims to have learned how to solve the puzzle faster by watching others giving tips on YouTube. He has consistently broken the world’s record for solving the puzzle—in breaking the record this time, he broke his own record of 5.8 seconds. The action in Melbourne was taped and posted to YouTube—Zemdegs can be seen preparing his cube, then solving it. The action is almost surreal, as if watching a robot in a sci-fi movie. Notably, he also holds other Rubik’s Cube records—the average time taken to solve five of the puzzles, for example, at 5.8 seconds. He is, quite naturally, a star in the speedcubing world—he has over 300,000 followers on YouTube and 90,000 Facebook users following his postings.In speaking with the press at prior events, Zemdegs has maintained that he doesn’t believe his prowess with the Cube suggests he has above-average intelligence. Instead, he has suggested it is more of matter of studying techniques and doing it a lot. He notes that after a while, it sort of becomes intuitive.
Be/X-ray binaries (Be/XRBs) consist of Be stars and, usually, neutron stars, including pulsars. Observations have found that most of these systems showcase weak persistent X-ray emission that is interrupted by outbursts lasting several weeks.Discovered in 1977, A0538−66 is a Be/XRB system located in the Large Magellanic Cloud (LMC). Many of the binary’s properties make it remarkable. For instance, it hosts one of the fastest spinning pulsars know to date—with a period of only 69 milliseconds. It has also one of the shortest orbital periods (about 16.64 days) and one of the highest eccentricities (approximately 0.72) among the Be/XRBs so far identified.During the first years after its discovery, A0538−66 was observed to emit bright X-ray outbursts with peak luminosity reaching even duodecillion erg/s. Afterward, the source entered a quiescent period during which its luminosity varied from 5.0 decillion to 40 undecillion erg/s.Now, a team of astronomers led by Lorenzo Ducci of Eberhard Karls University of Tübingen, Germany, reports that A0538−66 is once again active. Observations of this binary conducted last year with the use of XMM-Newton, show that it is emitting bright X-ray outbursts.”In 2018, we carried out XMM-Newton observations of A0538−66 during three consecutive orbits when the pulsar was close to periastron. In the first two observations, we discovered a remarkable variability, with flares of typical durations between two to 50 seconds and peak luminosities up to 400 undecillion erg/s (0.2−10 keV),” the astronomers wrote in the paper.According to the paper, the flares were absent when the source was observed for the third time in 2018, and its luminosity was measured to be about 20 decillion erg/s. Between the two outbursts, the luminosity was found to be about 10 times higher.The astronomers emphasized how powerful and fast the two observed outbursts were. They noted that such fast flaring activity has never been observed in A0538−66, or most probably any other known Be/XRB.Pondering the possible explanation for such peculiar flaring activity, the researchers point to transitions between the accretion and supersonic propeller regimes. However, although they find this scenario the most plausible, they do not exclude any other hypotheses at the moment. “Although other explanations for the observed variability cannot be excluded, we speculate that the strong and rapid flares occur because the source was accreting from a spherically symmetric flow, not mediated by an accretion disk. In these conditions, an atmosphere can form above the NS [neutron star] magnetosphere, and flares might be produced by rapid changes between the accretion and supersonic propeller regime,” the authors of the paper concluded.They added that more studies of spectral properties of A0538−66, focused at higher energies, could help verify the possible scenarios. © 2019 Science X Network XMM-Newton spectra of A0538−66 during the three luminosity levels, fitted with two absorbed power laws (plus a Gaussian line for the intermediate and high luminosity levels).

Using ESA’s XMM-Newton space telescope, astronomers have spotted bright X-ray outbursts emitted by a Be/X-ray binary known as A0538−66. The discovery marks the ending of an over three-decade-long period of quiescence of this system. The finding is detailed in a paper published July 18 on arXiv.org.

The moon is having a star turn. This summer will mark the 50th anniversary of the Apollo 11 lunar landing, and the Trump administration has ordered NASA to put astronauts back on the moon by 2024. None of this, however, will probably change the minds of people who live in a parallel belief universe where NASA faked the Apollo moon landings. The evidence that the moon landings were real is exactly what a conspiracist would expect to be manufactured by an agency committed to hoodwinking the public. This is the eternal conundrum for debunkers. Read the whole story: The Washington Post In response to a query from The Washington Post, NASA spokesman Allard Beutel issued a statement saying there is “a significant amount of evidence to support NASA landed 12 astronauts on the Moon from 1969-1972,” and specified some of that evidence: NASA has “842 pounds of astronaut-collected Moon rocks studied by scientists worldwide for decades; you can still bounce Earth-based lasers off the retroreflector mirrors placed on the lunar surface by the Apollo astronauts; NASA’s Lunar Reconnaissance Orbiter imaged the landing sites in 2011 . . . ” Polls show that about 5 or 6 percent of the public subscribes to the moon-hoax theory, former NASA chief historian Roger Launius said. That is a modest number, but these folks showed up reliably whenever Launius gave a lecture on the topic: “They’re very vocal — and they love to confront you.” And so on. But it’s a tough situation for NASA. The moon hoax isaclassic conspiracy theory — elaborate, oddly durable, requiring the existence of malevolent actors with a secret agenda. The moon-fakers are allegedly so competent they can fool the whole world (but not so competent that they can actually put humans on the moon). Researchers suggest conspiracy theories are spreading more easily in today’s information universe, with the Internet functioning as a superconductor. A growing science of conspiracism seeks to understand who these people are, why they embrace such ideas, and whether there is anything that can dislodge a really magnetic conspiracy theory from the mind of a true believer. As NASA celebrates Apollo 11, the space agency must decide whether, and how, to respond to the moon-hoax conspiracy theory.
Stolen from a ramshackle temple in a sleepy village of Uttar Pradesh that landed in the hands of an art collector in Paris, an exquisite 10th-century stone sculpture of the Yogini, the female emblem of India’s mystical cult, is now the prized possession of National Museum.The museum will celebrate the homecoming of the 4.5-foot-tall Vrishanana Yogini, the nearly 400-kg sculpture of a female deity with the buffalo-shaped head by holding a unique, first-of-its kind exhibition based on a single object. ‘In the past, National Museum has organised exhibitions focusing on specific themes, but it is for the first time that it is holding an exhibition on a single artefact,’ said Dr Venu V, the museum Director General. ‘Although the exhibition focuses attention on an object, there are multiple themes that underpin it.’ Also Read – ‘Playing Jojo was emotionally exhausting’The exhibition is to be jointly inaugurated by Culture Minister Chandresh Kumari Katoch and External Affairs Minister Salman Khurshid at the museum on 19 September at 3 pm.Dr Venu said a major objective of the exhibition is to increase awareness of the fascinating history of Yoginis and the elaborate rituals of their worship. ‘More importantly, it aims to bring into spotlight the disturbing reality of the continued illicit trafficking of India’s priceless cultural artefacts,’ he added.
Kolkata: A fire broke out on the 10th floor of a high-rise building in the central part of the city’s business area tonight, police said. Nobody was injured in the incident, they said. The fire broke out at around 8.45 PM due to some electrical malfunction in an office room, located on the 10th floor of the LIC building in the C R Avenue in Bowbazar police station limits, a senior Kolkata Police officer said.Five firetenders took almost 40 minutes to douse the blaze, he said.The Kolkata Police’s Disaster Management Group (DMG) team and police personnel from the Bowbazar police station were also present during the operations, he added.”The cooling process is still underway. None got hurt or trapped. We are yet to ascertain the extent of damages. The situation is under control, the officer added.
Drishyam released this Friday. How do you feel?(Cuts in with a smile) This is not my first film! But I’m curious to know how the audience will receive it. The audience has changed and their tastes are no longer what they were. They are looking for a change and are eager to watch content driven films. Drishyam is the kind of film that today’s audience is looking for.A change in the audience is a good sign for the industry, isn’t it?Yes. But that happens once in three or four years. I have been around for so many years and I’ve seen our audience evolving. And not just the audience but us filmmakers too. We’ve been trying to outdo ourselves with each movie that we make. What used to work with the audience doesn’t work now. We also need to respect the evolving audience and serve them what they want. That’s Drishyam! Also Read – A fresh blend of fameYou’re doing a film like this after a very long time, where your fans will not see you bashing up a villain.Yes, I agree but they won’t be disappointed. I may not use my fists in the film but, eventually, it is my character that defeats everyone. I use my intelligence to play a cat-and-mouse with everyone in the film. The movie keeps you on your toes because of the character I play.Don’t you think your audience will miss watching their hero?Absolutely NOT! What’s the definition of ‘hero’? A hero saves his lady love, his family, his friends and people, and that’s what I am doing in Drishyam. I play a regular guy who emerges as a hero in the end. His only aim in the film is to safeguard his family. My character is a very simple guy who adores his family. His universe comprises his work and his family, and when his family is in trouble, he takes charge and eventually saves them. Now that’s what a hero does, either on screen on in real life. And that’s the USP of the film. So, from the kids to the young generation to older people, everyone will relate to my character in the film. That’s where the triumph of the screenplay lies. Also Read – Martin Freeman confirms ‘Black Panther’ returnThe leading man in Drishyam is not weak; he is fighting the common man’s fight. The audience doesn’t accept Ajay Devgn playing a weak character. I have a certain image and it is very difficult to break that mould. But his style of fighting is very interesting. And everyone will fall in love with the character once he decides to fight for his family.Coming back to your previous question… Yes, I am doing cinema like this after a long time. It’s not that I didn’t want to do content-driven movies; it’s just that I wasn’t getting the right script. I would like to add that I was the one who acted in hardcore commercial movies but also worked in hard-hitting, content-driven movies like The Legend of Bhagat Singh, Naajayaz, Zakham or Company, and I even backed Dil Kya Kare. But everyone expects you to deliver a Rs 100-crore movie with every successive release.I know, whether we accept it or not, as stars, we are always under pressure to deliver. And this pressure is created by us and the media hype when we deliver a Rs 100-crore movie. Earlier, we used to celebrate silver and golden jubilees; now it’s the Rs 100-crore club. While such films don’t always open well, they pick up with word-of-mouth. I am not at all worried about the fate of Drishyam. I just want to ensure that the audience watch it. Every film has its own merits and limitations. We need to judge a film by its investment. Drishyam may not take a gigantic opening but neither will collections nosedive once the initial craze subsides. When a film like Drishyam comes along, you just know it has to be a part of your life!People often ask me why I don’t act in films like Zakhm any more or The Legend of Bhagat Singh. Now they are asking me ‘Why Drishyam?’ When I was doing successful commercial movies and also accepted films like Zakhm and The Legend of Bhagat Singh, they asked me the same question: ‘Why are you doing these movies?’ They received their answer when the movie released. The same thing happened on Friday. Everyone realised why I decided to do Drishyam. (Laughs)Why are the promotions of the film almost low key?Hype and publicity may work temporarily but content pays in the long run. When I decided to do Drishyam, I knew the kind of opening it would take. You see, when you get a script like Drishyam, all those box-office insecurities melt away because you know it will not get a great opening as it does not have masala, songs and the typical commercial elements that potboilers have. It’s a word-of-mouth film like Piku, which picked up after the third show. I am keeping my fingers crossed that Drishyam will do well from the first show. So there’s no need to go all out to promote the film.Also, since the film is an edge-of-the seat movie, we didn’t want to give out too many details. We want the audience to come to cinemas and enjoy the movie. Our promotions don’t reveal much but, at the same time, they are generating curiosity and reminding them that this movie will release on July 31. The whole idea was to tell the audience that after a hiatus, Ajay Devgn is doing a content-driven film like he has always been doing. I think we have managed to convey that.What kind of response are you receiving?You are from the trade… why don’t you tell me what the buzz around the film is like. As soon as the trailer released, everyone began looking forward to the film. And there’s a lot of curiosity among the audience since you’re doing this kind of cinema after a long time. Correct! Now that’s the response I too am getting. If I keep doing cinema like this, people won’t wait for my next. I need to serve up different movies to the audience. And since I’m doing a movie like this after a gap, there’s a hunger among the audience. I am told by the Viacom people that the response at their focus trial was great. There were people from all age groups and all of them loved the film. There was one screening in Delhi and one in Mumbai, and both received a tremendous response. I am sure the film will be appreciated and the audiences will love Drishyam but I want them to go in from the first day. After a long time, there is no anxiety arising out of the Friday pressure because we know that Drishyam may not take a great opening. But I am trying my best to make even that happen. If a film likeDrishyam takes a big opening, it could change the face of cinema because people will attempt better films on these lines.Since the film has already been made in the South, don’t you think there will be comparisons?We compare a film when it is not at par with the original. I wouldn’t say that Drishyam is much better than the original but it is definitely at par with the original. And whoever has seen the Malayalam version, will be more than entertained watching our movie. Those who have watched the film will like to watch our version for their sheer love of the original. And people who have not watched the original would watch it to experience this beautiful cinema called Drishyam.In a recent interview, Tabu said that her first successful film was with you, and now she’s working with you after a long time.(Laughs) I know she said that. She is an old friend. The film is a cat-and-mouse game between Tabu and me. I don’t know who thought of casting Tabu but it was a masterstroke. After watching the film I can say that no actor other than Tabu could have had carried this role the way she has. She’s fantastic in the film. Her performance is one of the key reasons the film is as entertaining as it is.
Kolkata: Three persons including a senior official of a tour agency have been arrested for duping people under the pretext of organising foreign trips for people.The accused used to publish advertisements in various newspapers and elsewhere attracting attention of people with various offers. The tour agency used to operate from the city. They used to collect a huge amount of money from people with the promise to arrange a whole foreign trip for them. After taking the money, they used to shift their office at some other place. Also Read – 3 injured, flight, train services hit as rains lash BengalOn the basis of two separate complaints, the city police initiated a probe in this regard. After starting an investigation, police came to know that the tour agency in the name of ‘Skylark Travels’ had duped many people. A Bangalore-based victim, M R Shashidhara, told police that the tour agency had arranged a trip for them in to the city in 2017. As a result they had also paid them over Rs 35 lakh for flights and hotels for a trip to Singapore, Malaysia and Thailand in 2018. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe agency had later sent them the flight tickets and hotel booking certificates through e-mail. They soon realised that all of them were fake. Following the incident they lodged a complaint. One Abhisek Patra, a resident of Narendrapur, had also fallen victim and got duped of Rs 1.24 lakh. The victim had paid the money as an advance sum for a trip to Singapore, Malaysia and Thailand. He registered a complaint after he found that the flight tickets given to him were false. After conducting a search, police arrested Rupayan Gupta, managing director of the company and Subhankar Mondal and Akash Pathak in this connection. Police came to know during the interrogation that Gupta was the main accused. The investigating officers are also probing if others are involved in the incident.
