For the fragments that contain stable hydrophobic contacts (which cause the protein to fold), the protein/computer enforces these contacts and adds more residues to enlarge these points. If new hydrophobic contacts are formed again, the process continues until no more contacts are found.“The protein doesn’t ‘know’ it has the right starting points at the early stages,” Dill explained. “It explores many possible avenues. But, we find that when the chain pieces have reached roughly the 16-to-24-mer stage, then the differences in free energy begin to become compelling, and structures begin to emerge fairly clearly.”In some cases, this zipping procedure alone is enough for a protein to reach its native form. For other cases, the ZA algorithm switches to the assembly procedure, combining two or more fragments to form additional structures until the native form is achieved. The ZA method was tested on nine small proteins, eight of which closely matched the experimental results of samples in the Protein Data Bank. The greatest sign that the ZA method is on the right track is its speed. For example, using ZA, protein G could fold in about 1 CPU year on a 2.8-Ghz Xeon Intel machine.“We don’t know exactly what the speed gain is,” Dill said. “Our largest protein studied is a 112-mer (subsequent to the PNAS paper). Currently the most extensive all-atom physical simulations on Folding@Home, with 100,000 processors, or IBM’s Blue Gene, built for this problem, are on smaller proteins, typically in the range of 20-40 amino acids long. However, those simulations are also more directed at physical questions of folding, rather than at protein structure prediction, so it’s hard to make a direct comparison.”Citation: Ozkan, S.

The physical strategy, called “zipping and assembly” (ZA), can increase the speed at which supercomputers predict protein folding structures, greatly increasing scientists’ understanding of these building blocks of life.

The scientists, Banu Ozkan, Albert Wu, John Chodera, and Ken Dill from the University of California at San Francisco, have published their research in a recent issue of the Proceedings of the National Academy of Sciences. Their results show that the ZA search strategy provides a physics-based model of protein folding that could lead to advances such as computer-based drug discovery and genetic engineering.“Our research has two significant points, I believe,” Dill told PhysOrg.com. “First, it shows that all-atom physical force fields are pretty good (but not perfect), and may be useful for protein structure prediction. And second, it proves that zipping and assembly is a highly efficient conformational search method, and supports the view that ZA may be the physical mechanism of protein folding.”Proteins, which consist of an unstructured linear chain of amino acids, can fold into complex 3D structures within microseconds. On the other hand, high-speed supercomputers might take tens of years to compute the correct structure due to the vast assortment of possible forms the protein could take. When folded incorrectly, proteins can cause neurodegenerative diseases such as Alzheimer’s and mad cow disease. How proteins fold so quickly is a mystery that researchers are approaching from many different angles, including, for example, physics-based force fields. By assigning force fields to different parts of the protein, computers can track the movement of each individual part.Using the ZA strategy, Ozkan, Wu, Chodera and Dill have sped up the rate at which computers using force fields can predict protein structures. In the ZA model, the first step that proteins (or computers) take is breaking the amino acid chain into 8-12 fragments to search for a very small fraction of favorable folding points (traditional methods usually search the entire chain).“The speed gain in our method comes from not exploring all possible folding routes, but instead from following only those routes that entail small conformational search steps,” Dill explained. “This reduces the search problem, in principle, from one that grows exponentially with the chain length to one that, instead, grows only as the first or second power of the chain length. While we haven’t actually proven that quantitatively, it is clear that the method is much faster than brute force Monte Carlo or molecular dynamics.” Parsley and dill help fight cancer, research shows This document is subject to copyright.

Image: Kyoto University The device is supposed to be especially handy for use in tight spaces; the intention is to help users of electric wheelchairs maneuver their movements with greater freedom than they have in the past. What is not such good news is that the vehicle on display cost $36,300 to produce, The research lead, Masaharu Komori, an associate professor of mechanical engineering at Kyoto University, is well aware of the price shortcoming and plans to continue work on the chair to bring costs down, and make the chair lighter and more compact. The eventual target price is $12,000. Komori and team hope to commercialize the Permoveh in three to five years.This Permoveh “rollout” comes at a time when Japan is showing much interest in bringing on improved assistive technology, from robots to motorized chairs, that can help the elderly. Among the innovations reported have been a bed that changes into an electric wheelchair and a robot that can wash hair.Whether or not this omnidirectional vehicle can eventually be a popular wheelchair of choice (the top speed is 3.7 mph) for the elderly remains to be seen, but it is being suggested that the Permoveh wheel technology could be adapted for use in conveyor equipment in factories and warehouses. One site notes the wheel technology is like that seen in Honda’s “U3-X” which also enables the rider to move backwards, forwards, and side to side using an omnidirectional wheel. Honda’s description about how the wheel structure enables movement in all directions is that “multiple small-diameter motor-controlled wheels are connected in-line to form one large-diameter wheel. Rotating the large-diameter wheel moves the U3-X forward and backward, while rotating the small-diameter wheels moves it side-to-side. Combining these movements causes the U3-X to move diagonally.” This document is subject to copyright.

Japan’s Honda unveils futuristic unicyle (w/ Video) Explore further (PhysOrg.com) — A mechanical engineering professor has taken the wraps off his vehicle that is designed to become a next-generation wheelchair. As its formal name suggests, this is the Personal Mobile Vehicle, or Permoveh for short. Rolling it around at his lab in Kyoto, Japan, earlier this month, the professor carried out the demo before an audience of observers and photographers. They watched him ride the device, with its clever wheel-within-wheel system, which allowed the vehicle to move in any direction. The Permoveh has four same-sized wheels with 32 rollers each. They rotate in a perpendicular direction to the rim. The rollers sit inside the main wheels, allowing the vehicle to move in more directions than just back and forth.

Reassessing the chronology of the archaeological site of Anzick, Proceedings of the National Academy of Sciences (2018). DOI: 10.1073/pnas.1803624115AbstractFound in 1968, the archaeological site of Anzick, Montana, contains the only known Clovis burial. Here, the partial remains of a male infant, Anzick-1, were found in association with a Clovis assemblage of over 100 lithic and osseous artifacts—all red-stained with ochre. The incomplete, unstained cranium of an unassociated, geologically younger individual, Anzick-2, was also recovered. Previous chronometric work has shown an age difference between Anzick-1 and the Clovis assemblage (represented by dates from two antler rod samples). This discrepancy has led to much speculation, with some discounting Anzick-1 as Clovis. To resolve this issue, we present the results of a comprehensive radiocarbon dating program that utilized different pretreatment methods on osseous material from the site. Through this comparative approach, we obtained a robust chronometric dataset that suggests that Anzick-1 is temporally coeval with the dated antler rods. This implies that the individual is indeed temporally associated with the Clovis assemblage. Artifacts from the Anzick site. Credit: Texas A&M University In 1968, construction workers came upon the remains of an infant skeleton. Those remains became known as Anzick-1 and were believed to represent a member of the Clovis people. The Clovis people are believed to have been the first widespread group of people living in North America. Prior research has suggested they lived approximately 13,000 to 12,600 years ago. Their name comes from the distinctive Clovis-style projectiles they created.In the years after Anzick-1 was found, teams of researchers studying the remains found mixed results when testing for age. Some showed the remains as very nearly the same age as nearby Clovis artifacts, while others found the remains to be thousands of years more recent. In this new effort, the researchers sought to settle the matter once and for all using new and improved dating techniques.The new techniques involved using pretreatments of collagen found in the remains to factor out decontamination and for extracting a single amino acid for radiocarbon dating. The researchers report that all of their tests showed that antlers found near the burial site and the skull of a second specimen (Anzick-2) were roughly the same age—which was approximately the same as prior testing had shown. But some of the testing showed the remains of Anzick-1 to be approximately 1000 years younger. Another test the team performed, though, called HYP extraction, showed the infant remains to be approximately the same age as the antlers and Anzick-2. The differing results from the other tests, the researchers suggest, were likely due to contamination issues. They contend that because HYP is the more precise measurement technique, their results show that Anzick-1 is approximately the same age as the other artifacts. And this, they claim, suggests that the debate about the age of the remains should be considered resolved. A team of researchers from the University of Oxford, Texas A&M University and Stafford Research LLC has found evidence bolstering the theory that the skeletal remains of an infant unearthed in Montana are those of the only known Clovis burial. In their paper published in Proceedings of the National Academy of Sciences, the group describes their testing methods and what they found.

In an ironic twist, physicists have shown that the very property that can be used to show that quantum computing devices can solve some problems that classical computers cannot also makes it impossible to efficiently certify that this “quantum supremacy” has indeed been achieved, for a wide variety of schemes. In quantum computing, the issue of certification is crucial for formally verifying the superior computing power of quantum devices.

Our work also points towards a potential way out of this dilemma: interactive or quantum certification protocols.”The term “quantum supremacy” refers to the possibility that quantum computing devices can solve some problems that are practically infeasible for classical computers to solve. One problem that is considered intractable for classical computers is random sampling from certain very flat distributions (in which all outcomes are nearly equally likely) over exponentially large datasets. Currently, no universal, fault-tolerant quantum computer is available to experiment with, but even the limited quantum devices that are available today are thought to be capable of performing the random sampling task. Intuitively, this is because quantum devices can prepare a state in the correct superposition of all elements of a set, while classical devices need to access the exponentially many probabilities one by one. One of the limitations of all physical devices (quantum or classical) is that they are only capable of approximate sampling. So in order to demonstrate quantum supremacy, researchers must show that a quantum device’s approximate sampling is close enough to ideal sampling so that it is still intractable for classical computers. All current proofs of this concept, which is called approximate sampling hardness, use small second moments. In the random sampling task, a distribution is randomly chosen. Essentially, small second moments mean that the randomly chosen distribution concentrates around the uniform distribution and is therefore very flat. In the new paper, the researchers show that small second moments also forbid efficient certification from the samples alone. That is, sampling distributions with small second moments cannot be certified with polynomially many samples, but instead require exponentially many samples. This makes certification inefficient and unrealistic to perform in a reasonable amount of time. The results hold for a variety of widely used sampling schemes, including boson sampling and universal random circuit sampling, among others. However, the results do not mean that efficient certification is necessarily impossible by any method. The researchers hope that, instead, the findings will motivate the development of alternative certification schemes, as well as proofs of approximate sampling hardness that apply to distributions with larger second moments. “Our work guides the way for where to look for feasible certification schemes,” Hangleiter said. “In particular, it often makes sense to use device-specific knowledge to leverage certification. One direction of research is to develop device-specific certification schemes both for quantum sampling schemes, but thinking further, also for more elaborate tasks that can be performed on quantum computers. “Quantum sampling schemes are very ‘clean’ quantum supremacy proposals in the sense that they allow for a complexity-theoretic hardness argument. At the same time, they do not have real applications (yet). A second direction of research is to develop schemes that are feasible on near-term devices and yet hard, which also solve a useful task, as well as to find applications for the known sampling schemes.” A test to certify quantum supremacy will accept a probability distribution if it is classically hard, and otherwise will reject it.

The evening’s repertoire will showcase a diverse range of music, bringing out the contrast and subtle shades and themes that run through different genres from sacred and gospel to Western and Indian classical compositions and a few popular pieces as well.The next highlight of the month is screening of the film Children of Glory on May 7. The movie commemorates Hungary’s Revolution of 1956 and the ‘Blood in the Water’ match. Taking place in Budapest and at the Melbourne Olympic Games in October and November of that year, the film takes viewers into the passion and sadness of one of the most dramatic popular revolts of the twentieth century. In the same year, Soviet tanks were violently suppressing the Revolution in Hungary, when the Hungarian water polo team was winning over Russia in the Olympic pool in Melbourne. This event is sometimes described as the bloodiest water polo match in history. While telling the story of 1956 in part through fictional lead characters, the film-makers simultaneously recreated many of the key public events of the Revolution, including the huge demonstrations and the street fights in the of Budapest.

There are others involved in the racket as well, police suspect. According to the cops, as many as 14 gold biscuits were found in his possession weighing around 600 grams. It may be mentioned that the police and Customs have intercepted a number of youths in the district in the past few months and seized gold from them. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedA probe is being conducted to ascertain if there are any connections between all the incidents. The district police have also intensified the surveillance in the bordering areas of Bongaon. The preliminary investigation suggests that the accused changed route following some recent incidents in which smugglers bringing gold bars and biscuits from abroad were intercepted at Kolkata airport. The accused then began smuggling gold along the India-Bangladesh border in certain districts. As there was stringent surveillance in all the airports these days, it has become difficult for the smugglers to bring in gold from abroad.
Kolkata: The state government has not given any order to suspend screening of the film The Accidental Prime Minister, Indranil Sen, minister of state for Information and Cultural Affairs, said on Friday.The matter came to front after the authorities of Hind Inox suspended the first show of the film, following a protest by Youth Congress supporters in front of the cinema hall. However, the second show was screened on time. Youth Congress supporters led by Suman Pal staged a demonstration outside the movie theatre on Friday afternoon. They raised slogans against Prime Minister Narendra Modi and burnt his effigy. The screening of the first show was in progress when the incident took place. The authorities of Hind Inox suspended the show for the safety and security of the employees.

The Indian Tricolour is one of the most beautiful flags in the world. Each colour including that of Ashoka Chakra holds meaning and significance. But there are many people (Visually impaired) who aren’t fortunate enough to witness and appreciate this pretty sight. They are deprived of the joy of fluttering colours.To give such visually challenged children an idea of the national flag, MP Birla Cement has crafted a “Flag Without Colours”. Made of cement, this flag brings out the colours and symbol of the flag through braille markings.

This is a small endeavour on our part to make the celebrations of Republic Day more inclusive and carry the message of national flag to a wider cross-section of our young citizens”. “Cement is usually seen as a very inanimate material and its role in nation building is not easily recognised. The philosophy of the MP Birla Group is ‘Heart and Strength’. This is an expression of that core value, which guides our organisation. In the course of the year, we plan to take braille flag to many more institutions like Seva Mandir as our homage to the nation,” he further added. “Republic Day emphasises human rights and honours the freedom that national flag represents. This was just a humble attempt of including those who have been deprived of sight in a celebration that is rightfully theirs. I can only hope that the ‘Readable Flag’ will become as common a sight as the tricolour someday”, said Sujoy Roy, Executive Creative Director, Ogilvy Kolkata.

4 min read Belkin Gigabit AOSS secure connection system Nfiniti Notebook Adapter WLI-CB-G300N MANUFACTURER/ MODEL RangeMax NEXT Wireless Adapter Gigabit Edition (WN511T) Growing a business sometimes requires thinking outside the box. ROUTER September 1, 2006 (800) 2-BELKIN, www.belkin.com (800) 326-1688, www.dlink.com Wireless-N PC Card (WPC300N) CARD N1 Wireless Router $200 (router), $110 (card) Wi-Fi being so popular, wireless network vendors are constantly pushing the envelope. Last year, their pre-n wave of network adapters delivered the multi-pathing MIMO element of the upcoming 802.11n specification. Since the spec’s first draft was approved, they’ve launched another wave of so-called draft-n hardware using another 802.11n innovation–bonding transmission channels together to get throughput as high as 300Mbps. Draft-n hardware is supposed to make your network 12 times faster than 802.11g adapters and quadruple its range. (For more on Draft-n, see “Not-So-Rough Draft”)Sites vary widely, so don’t count on getting those numbers. Still, we got consistently good performances from the draft-n adapters we tested. We started by checking compatibility, and contrary to press reports, draft-n worked just fine with older 802.11g and MIMO hardware. We got better range than normal when mixing 802.11g and draft-n gear, and 54Mbps speeds with only occasional dips to 48Mbps or lower. That means you can upgrade your hardware piecemeal with little chance of complications.When using all draft-n gear, speeds ranged widely depending on distance and obstacles between router and PC card. Draft-n has two-dozen rollback levels and a tendency to roll up and down among the speed points as the environment changes. We hit 270Mbps occasionally, but a more reasonable expectation is something north of 100Mbps on a regular basis–more than enough for most business applications. The greatest fluctuations came when we mixed hardware from different makers. So if you have a favorite brand, you’re probably better off sticking with it for all your hardware.In terms of usability, Buffalo’s AirStation One-Touch Secure System, or AOSS, is a nice extra that lets you connect your AOSS-enabled adapters securely with the push of a button. It doesn’t require you to enter encryption settings on every computer you want connected. In related features, Netgear’s Touchless Security Wizard also simplifies the process of setting up your Wi-Fi security through the use of passphrase. We tried out the robust gigabit edition of the Netgear router, which will appeal to high-bandwidth users who are already using gigabit Ethernet adapters. The Linksys Small Business Wireless- N Router WRV4400N costs a bit more than the others because, besides a gigabit switch, it’s equipped with extensive quality and security features.Ease-of-use is paramount in network adapters, especially if you can’t fob installation off on an IT person. But vendors have done this before, and their step-by-step software wizards should guide you through the setup process. The front panel of the Belkin N1 Wireless Router features light-up icons so you can visually trace your router’s connections. Linksys also features well-designed Wireless Monitor software. As hassle-free as setup is, though, you still have to set up network encryption yourself. All the manufacturers offer free phone technical support to help resolve any problems.Manufacturers are still working on refining these products and can’t guarantee interoperability or upgradeability to an 802.11n spec that hasn’t been finalized. But they do plan to offer timely firmware upgrades to bring your equipment up-to-date. One of your first recourses should be to check for any available updates.If you’re not in pressing need of a Wi-Fi upgrade, it won’t hurt to wait for the next round of improved firmware or even for the finalization of the 802.11n specification. On the other hand, this hardware is affordable enough to use for a year and then upgrade again.

3-D printing has made waves in industries from fashion to space to biotech. It’s also poised to radically transform the way we think about and prepare food.Image credit: Modernist Cuisine | Vimeo That was the takeaway from a talk on the future of 3-D printing given Wednesday at the Tribeca Film Festival by 3D Systems’ chief entrepreneur officer Ping Fu, who announced that the company will be launching a consumer chocolate 3-D printer this year.3-D printing technology is already being used by high-end chefs — she shared a video of an elaborate 50 course meal prepared by the Modernist Cuisine’s Nathan Myhrvold that integrated 3-D printed elements — but has yet to go mainstream.Video credit: Modernist Cuisine | VimeoFu predicts that will soon change. “I believe the food printer will be the first one that is going to be adopted in everybody’s home,” she told the audience, painting a picture of a near-future where cooking a meal is redefined as designing it on a computer and then printing it out in the kitchen. “3-D printing will allow delicious nutritious food with great presentation to be delivered locally.”Related: How a 3-D Printer Just Gave This Little Girl an Awesome, New Prosthetic HandIt will also allow individuals to ‘cook’ for friends and family members remotely. When her daughter was growing up, Fu often had to work late at the office. She wanted to somehow still cook her dinner, a futile fantasy. At least, it was back then. “With a 3-D printer, this is totally possible,” she said.We’re still a long ways from 3-D printing entire meals, and Fu understands that for many people, 3-D printing dinner may feel like cheating, replacing a messy, joyful social process with a cold and clinical one.She urged the audience to keep an open mind. Replacing cooking with 3-D printing doesn’t necessarily make the process less social. Just instead of collaborating in the kitchen, families will “co-create” around the computer.

April 30, 2015 Regular readers will recall that my first date with the Apple Watch did not go smoothly. I was wearing it wrong. The apps were sluggish. The first time I tried to message a friend it crashed.One week later, I still don’t love it. But I am having feelings. Mostly after small victories.I felt something when I figured out how to tune Twitter so that I wasn’t bombarded with notifications.I felt something when, six days later, I managed to add someone to my friends screen.I felt something when I began to get comfortable with the interface vocabulary — the vertical swipes, the horizontal swipes, the force touch, the digital crown.“Do not expect to strap on Apple Watch for the first time and feel entirely at home,” says Daring Fireball’s John Gruber in Watch, Apple Watch, an essay that makes a useful distinction between needing a wireless computer on your wrist and wanting one.This is a device that demands exploration. It needs to be mastered. It needs to be fine-tuned to fit your digital lifestyle.And when it does, when Apple’s “most personal” device starts to feel at home, you can’t help bonding with it.I’m reminded of the way people who mastered a complex piece of pre-WYSIWYG software — the typists who memorized WordPerfect’s obscure keystroke combinations, for example — clung to it until their cold dead fingers had to be pried off the keyboard.I’ve searched for a term to describe this phenomenon, and I think I’ve found it: Stockholm syndrome. Here’s how Wikipedia, borrowing from an FBI Law Enforcement Bulletin, defines it.Stockholm syndrome, or capture-bonding, is a psychologicalphenomenon in which hostages expressempathy and sympathy and have positive feelings toward their captors, sometimes to the point of defending and identifying with the captors. These feelings are generally considered irrational in light of the danger or risk endured by the victims, who essentially mistake a lack of abuse from their captors for an act of kindness.Mistaking a lack of abuse for an act of kindness. That’s me and my Apple Watch, one week later.

Henry T. Casey, Author Bio When Apple rolled out the iPad’s dock and split view, I thought the former was the only place you could drag apps in for multitasking modes. Dear reader, I’m ready to admit I was wrong.It turns out you can pull apps from another direction: the top of your iPad’s screen. Yes, Spotlight, the search field found by swiping down on the home screen, can help you open apps in either half of a split-view mode, or into the slide-over mode.MacBook Air vs MacBook Pro: Which 13-inch MacBook Is Right For You?Apple’s entry-level MacBook Air and Pro look pretty similar, but our testing proved they differ in crucial ways.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Which Cheap Tablet Is Best?

I find it useful to open the Music or Spotify apps, which I don’t always keep docked, because at home, I’m often listening to music via another device.Where to drop that app iconThen, once you see the app icon appear in your search results, drag-and-drop it out of the field, as it works just like a home screen app.If you’re using only one app, drop it onto the right margin of your screen to split your screen between that app and the one you were using.If you’ve already got two apps open, you’ve got two options. First, you can drop it on one-half of your split-screen view, to replace an open app.To view this app as a tile that slides over your two open apps, drag it onto the dividing line between your existing apps.Credit: AppleHow to Download YouTube Videos on iPhone or iPadHow to Send Safari Pages From One Device to AnotherHow to Change the Apple ID on an iPad by Taboolaby TaboolaSponsored LinksSponsored LinksPromoted LinksPromoted LinksYou May LikeVikings: Free Online GameIf you’re over 40 – this game is a must!Vikings: Free Online GameUndoKelley Blue Book5 Mid-engine Corvettes That Weren’tKelley Blue BookUndoGrepolis – Free Online GameGamers Around the World Have Been Waiting for this GameGrepolis – Free Online GameUndoMayo ClinicManaging psoriatic arthritis painMayo ClinicUndoTODAYCeline Dion Discusses Her Recent Weight Loss: ‘Everything’s Fine’TODAYUndoMy Food and FamilyHealthy, Homemade Drunken Thai Noodles In Just 20 MinutesMy Food and FamilyUndoAdvertisement Henry is a senior writer at Laptop Mag, covering security, Apple and operating systems.

Google News Alternatives by Martin Brinkmann on July 10, 2017 in Companies, Google – Last Update: January 04, 2018 – 46 commentsGoogle launched a new design for the company’s Google News service recently which Google stated was a long overdue modernization of it.As is the case with most fundamental changes to a service, Google has not received only love for the change but also criticism.While mobile users seem to be fine with Google News for the most part, at least some desktop users are not. They state that there is too much widespace, and that the layout is not optimized for going through news quickly anymore as less news articles are displayed on the visible part of a page.The option to vote with your pageviews exists, and it is probably one of the most useful ones in an Internet user’s arsenal.Google News AlternativesThe alternatives are listed in two groups below: first a group of news sites that is reviewed individually, and then a second group with alternatives that are mentioned only briefly.Bing NewsBing News is a mainstream news aggregator that is available in multiple localized editions. It highlights top stories on its front page, and pulls news from newspapers, and online publications.The homepage features trending topics as well from all areas of interest. You may filter news by type, for instance World or US news, and access news on important events directly there as well.NewsmapNewsmap is quite the interesting service, and not only because it uses a non-traditional design for displaying news on its site.Newsmap color codes news and displays news headlines in different sizes on the page. All colors are displayed at the bottom of the interface for easy reference, and an option to hide certain types of news.If you are not interested in health for instance, you can toggle the news topic off there to remove health related articles from the display. Another option that is displayed there is to change the time period that news articles have to be published in for them to be listed by Newsmap.It is furthermore possible to change the language of news from English to a dozen other languages or regions including Germany, France, or Spain.Some entries may be barely readable, but you can hover the mouse over any to display the title, first paragraph and other information such as the publication it was published in.The service pulls data from Google News.Wikipedia: Current EventsThis is not your typical all-news covering news portal, but a selection of major events from around the world.You may switch between worldwide current events and sports events on the site, and get a selection of news topics and topics by date on the page.Note that you may select one of the languages displayed on the left to list language specific news. These may differ highly, and some appear to be updated less frequently than others.The right sidebar lists ongoing events, sport events, elections and referendums, or deaths for easy access.Or, Legiblenews.Other Google News AlternativesLeft Right Center is focused on news from the US. It lists sources that are left or right leaning to provide readers with all points of views on topics.Memeorandum is for politics what Techmeme is for technology. The site covers only political news, and pulls data from a variety of online publications.New York Times Morning Briefing, a once a day summary (but not on weekends).Reddit/r/news is the news hub of Reddit. Users post and vote on news on the site, and since it is one of the largest sites out there on today’s Internet, it never takes long for important stories to be linked and discussed on the site.The States Report covers national and world news (and others), and lists news in an easy to access way on its site.Techmeme covers only technology news and pulls news from all major tech publications on the Internet. What I like about it is that it often lists multiple sources for news articles.Virwire pulls news from around the world and displays them in a simple layout that is optimized for mobile but accessible on desktop systems as well.Yahoo News is another mainstream news source. It is very similar to Bing News in scope. One major difference is that the first click on news links opens part or even all of the story on Yahoo News.Now You: Have another alternative for Google News that works well on the desktop? Feel free to share it below in the comment section.SummaryArticle NameGoogle News AlternativesDescriptionThe article lists Google News alternatives that work well on the desktop, and is a direct response of Google changing the design of its service.Author Martin BrinkmannPublisher Ghacks Technology NewsLogo Advertisement
