Schematic drawing of a 2D-material-based lateral (left) and vertical (right) Schottky diode. For broad classes of 2D materials, the current-temperature relation can be universally described by a scaling exponent of 3/2 and 1, respectively, for lateral and vertical Schottky diodes. Schottky diode is composed of a metal in contact with a semiconductor. Despite its simple construction, Schottky diode is a tremendously useful component and is omnipresent in modern electronics. Schottky diode fabricated using two-dimensional (2D) materials have attracted major research spotlight in recent years due to their great promises in practical applications such as transistors, rectifiers, radio frequency generators, logic gates, solar cells, chemical sensors, photodetectors, flexible electronics and so on. The understanding of 2D material-based Schottky diode is, however, plagued by multiple mysteries. Several theoretical models have co-existed in the literatures and a model is often selected a priori without rigorous justifications. It is not uncommon to see a model, whose underlying physics fundamentally contradicts with the physical properties of 2D materials, being deployed to analyse a 2D material Schottky diode. Reporting in Physical Review Letters, researchers from the Singapore University of Technology and Design (SUTD) have made a major step forward in resolving the mysteries surrounding 2D material Schottky diode. By employing a rigorous theoretical analysis, they developed a new theory to describe different variants of 2D-material-based Schottky diodes under a unifying framework. The new theory lays down a foundation that helps to unite prior contrasting models, thus resolving a major confusion in 2D material electronics. "A particularly remarkable finding is that the electrical current flowing across a 2D material Schottky diode follows a one-size-fits-all universal scaling law for many types of 2D materials," said first-author Dr. Yee Sin Ang from SUTD. Universal scaling law is highly valuable in physics since it provides a practical "Swiss knife" for uncovering the inner workings of a physical system. Universal scaling law has appeared in many branches of physics, such as semiconductor, superconductor, fluid dynamics, mechanical fractures, and even in complex systems such as animal life span, election results, transportation and city growth. The universal scaling law discovered by SUTD researchers dictates how electrical current varies with temperature and is widely applicable to broad classes of 2D systems including semiconductor quantum well, graphene, silicene, germanene, stanene, transition metal dichalcogenides and the thin-films of topological solids. "The simple mathematical form of the scaling law is particularly useful for applied scientists and engineers in developing novel 2D material electronics," said co-author Prof. Hui Ying Yang from SUTD. The scaling laws discovered by SUTD researchers provide a simple tool for the extraction of Schottky barrier height -- a physical quantity critically important for performance optimisation of 2D material electronics. "The new theory has far reaching impact in solid state physics," said co-author and principal investigator of this research, Prof. Lay Kee Ang from SUTD, "It signals the breakdown of classic diode equation widely used for traditional materials over the past 60 years, and shall improve our understanding on how to design better 2D material electronics."

Ultra-fast vibrations can be used to heat tiny amounts of liquid, experts have found, in a discovery that could have a range of engineering applications. The findings could in theory help improve systems that prevent the build-up of ice on aeroplanes and wind turbines, researchers say. They could also be used to enhance cooling systems in smartphones and laptops, and make it possible to develop appliances that dry clothes more quickly using less energy. Scientists have shown for the first time that tiny quantities of liquid can be brought to a boil if they are shaken at extreme speeds. A team from the University of Edinburgh made the discovery using computer simulations. Liquid layers one thousand times thinner than a human hair can be boiled using extremely rapid vibrations -- a million times faster than the flapping of a hummingbird's wings. The motion of the vibrating surface under the fluid is converted into heat as liquid molecules move and collide with each other, the team says. It is only possible to use vibrations to boil extremely small quantities of liquid -- contained within a few billionths of a meter above the vibrating surface, researchers say. Energy from vibrations applied to larger volumes instead produces tiny waves and bubbles, and only a very small amount of heat. The team used the ARCHER UK National Supercomputing Service -- which is operated by EPCC, the University's high-performance computing facility -- to run its simulations. The study, published in the journal Physical Review Letters, was supported by the Engineering and Physical Sciences Research Council. Dr Rohit Pillai, of the University of Edinburgh's School of Engineering, who led the study, said: "Exploiting this new science of vibrations at the smallest scales could literally shake things up in our everyday lives. The advent of nanotechnology means that this discovery can underpin novel engineering devices of the future."

While most interaction with digital content is still constrained to keyboards and 2-D touch panels, augmented and virtually reality (AR/VR) technologies promise ever more freedom from these limitations. AR/VR devices can have their own drawbacks, such as a tendency to induce visual motion sickness or other visual disturbances with prolonged usage due to their stereoscopy or auto-stereoscopy based designs. One promising solution is to adapt holography or light field technology into the devices instead. This, however, requires additional optics that would increase the size, weight, and cost of these devices -- challenges that have so far prevented these devices from achieving commercial success. Now, a group of researchers in Japan and Belgium has begun to explore a combination of holography and light field technologies as a way to reduce the size and cost of more people-friendly AR/VR devices. They will present their work during The Optical Society's (OSA) Frontiers in Optics meeting, 16-20 September, in Washington, D.C. One of the themes of the meeting is virtual reality and augmented vision, with both a visionary speaker and a series of invited talks on those subjects. "Objects we see around us scatter light in different directions at different intensities in a way defined by the object's characteristic features -- including size, thickness, distance, color, texture," said researcher Boaz Jessie Jackin of the National Institute of Information and Communication Technology in Japan. "The modulated [scattered] light is then received by the human eye and its characteristic features are reconstructed within the human brain." Devices capable of generating the same modulated light -- without the physical object present -- are known as true 3-D displays, which includes holography and light-field displays. "Faithfully reproducing all of the object's features, the so-called 'modulation,' is very expensive," said Jackin. "The required modulation is first numerically computed and then converted into light signals by a liquid crystal device (LCD). These light signals are then picked up by other optical components like lenses, mirrors, beam combiners and so on." The additional optical components, which are usually made of glass, play an important role because they determine the final performance and size of the display device. This is where holographic optical elements can make a big difference. "A holographic optical element is a thin sheet of photosensitive material -- think photographic film -- that can replicate the functions of one or more additional optical components," said Jackin. "They aren't bulky or heavy, and can be adapted into smaller form factors. Fabricating them emerged as a new challenge for us here, but we've developed a solution." Recording, or fabricating, a hologram that can replicate the function of a glass-made optical component requires that particular optical component to be physically present during the recording process. This recording is an analogue process that relies on lasers and recording film; no digital signals or information are used. "Recording multiple optical components requires that all of them be present in the recording process, which makes it complex and, in most cases, impossible to do," said Jackin. The group decided to print/record the hologram digitally, calling the solution a "digitally designed holographic optical element" (DDHOE). They use a holographic recording process that requires none of the optical components to be physically present during the recording, yet all the optical components' functions can be recorded. "The idea is to digitally compute the hologram of all the optical functions [to be recorded and] reconstruct them together optically using a LCD and laser," said Jackin. "This reconstructed optical signal resembles the light that is otherwise modulated by all of those optical components together. The reconstructed light is then used to record the final holographic optical element. Since the reconstructed light had all optical functions, the recorded hologram on the photosensitive film will be able to modulate a light with all of those functions. So all of the additional optics needed can be replaced by a single holographic film." In terms of applications, the researchers have already put DDHOE to the test on a head-up light field 3-D display. The system is see-through, so it's suitable for augmented reality applications. "Our system uses a commercially available 2-D projector to display a set of multi-view images onto a micro-lens array sheet -- which is usually glass or plastic," said Jackin. "The sheet receives the light from the projector and modulates it to reconstruct the 3-D images in space, so a viewer looking through the micro-lens array perceives the image in 3-D." One big difficulty their approach overcomes is that light from a 2-D projector diverges and must be made collimated into a parallel beam before it hits the micro-lens array in order to accurately reconstruct the 3-D images in space. "As displays get larger, the collimating lens should also increase in size. This leads to a bulky and heavy lens, the system consuming long optical path length and also the fabrication of the collimating lens gets costly," said Jackin. "It's the main bottleneck preventing such a system from achieving any commercial success." Jackin and colleagues' approach completely avoids the requirement of collimation optics by incorporating its function on the lens array itself. The micro-lens array is a fabricated DDHOE, which includes the collimating functions. The researchers went on to create a head-up, see-through 3-D display, which could soon offer an alternative to the current models that use the bulky collimation optics.

For the 30 per cent of Canadians who live within 500 metres of a major roadway, a new study reveals that the type of vehicles rolling past their homes can matter more than total traffic volume in determining the amount of air pollution they breathe. A two-year U of T Engineering study has revealed large trucks to be the greatest contributors to black carbon emissions close to major roadways. Professor Greg Evans hopes these results gets city planners and residents thinking more about the density of trucks, rather than the concentration of vehicle traffic, outside their homes, schools and daycares. The study was recently published in the journal Environmental Science & Technology. "I've been asked by people, 'We live near a high-traffic area, should we be worried?' My response is that it's not so much about how much traffic there is, it's more about the percentage of trucks, older trucks in particular." The comprehensive study -- led by Evans and collaborators at Environment and Climate Change Canada, and the Ontario Ministry of the Environment, Conservation and Parks, as well as the Metro Vancouver Regional District -- involved measuring vehicle emissions near roads in Vancouver and Toronto, including the 401, North America's busiest stretch of highway. The difference between emission levels across the sites was more correlated with the number of large trucks on the road rather than number of cars. Researchers found that air pollution levels right beside a major trucking route within a city were close to levels seen beside Highway 401, despite the road carrying less than one-tenth of the vehicle traffic. "This was in part due to differences in wind and proximity to the road but, surprisingly, the number of vehicles didn't make that much of a difference," said Evans. The data also revealed a significant drop in emissions on the 401 on the weekends, when personal vehicle traffic is still very high, but the volume of large truck traffic is low. Research consistently links traffic emissions to negative effects on both the environment and human health. "Whether it be cancer, respiratory problems, cardiac problems or neurodegenerative problems, there are numerous adverse health effects associated with the chemicals in these emissions," said Evans. "If we were able to reduce emission of pollutants like black carbon, we would also see an immediate climate benefit." Black carbon -- commonly called soot -- is a marker for exposure to diesel exhaust which is known to have negative health effects. Evans points out that modern trucks have made large improvements in their emissions -- it's the older diesel trucks that are the real culprits. "Those big, 18-wheeler diesel trucks last for a long time. We need to push to retrofit these old trucks with better emission treatment systems. Simply retrofitting the worse offending trucks, or getting them off the road, is a tremendous opportunity to improve air quality in our cities." The study will be part of a larger report in December that will stress the importance of implementing long-term monitoring of traffic related air pollution in Canada, and indicating that targeting high-emitting vehicles such as old trucks can provide a path towards improving near-road air quality. In the meantime, Evans hopes the study gets Canadians thinking about the effects of working, playing and living near truck-related air pollution. "When a cyclist is riding near a large truck

Mitosis -- how one cell divides and becomes two -- is one of the fundamental processes of life. Researchers at EMBL have now produced the first interactive map of proteins that make our cells divide, allowing users to track exactly where and in which groups the proteins drive the division process forward. This first dynamic protein atlas of human cell division is published in Nature on 10 September 2018. In 2010, a large study led by the same EMBL group identified which parts of the human genome are required for a human cell to divide, as part of the EU MitoCheck project. But cells don't run on genomic DNA; they run on the proteins it encodes. Proteins carry out most of the work in a cell, forming the cell's operational level. Processes like mitosis require the tight coordination of hundreds of different proteins in space and time. Proteins often work in groups, similar to the specialist teams of construction workers on a large building site. "Until now, individual labs have mostly been looking at single proteins in living cells," says Jan Ellenberg, the group leader at EMBL who led the project. "Supported by the follow-up EU project MitoSys we were now able to take a systems approach, and look at the bigger picture by studying the dynamic networks many proteins form in living human cells." The resulting Mitotic Cell Atlas integrates these data in an interactive 4D computer model. In this public resource, scientists can freely choose any combination of mitotic proteins and see in real time where and with whom they work during cell division. Five different proteins are tracked during cell division (from metaphase to telophase): AURKB (red), NUP107 (green), CENPA (purple), CEP192 (yellow), and TUBB4B (cyan). The video* represents what users could create by themselves when using the mitotic cell atlas homepage: http://www.mitocheck.org/mitotic_cell_atlas/ Sharing the tools to make more cell atlases Cell division is an essential process of life. When it goes wrong, defects like fertility issues and cancer can occur. Ellenberg: "Besides mitosis, the technologies developed here can be used to study proteins that drive other cellular functions, for example cell death, cell migration or metastasis of cancer cells. By looking at the dynamic networks these proteins form, we can identify critical vulnerabilities, points where there's only one protein responsible to link two tasks together without a back-up." Looking at disease relevant processes from a dynamic network point of view provides a new perspective to find their critical links, where they can be cut or rewired to strengthen them. To enable more such studies in the future, the experimental methods, the quantitative microscopy platform, and the code to create dynamic protein atlases are now openly available for others to use. Counting proteins in living cells The current study looked at HeLa cells, a widely used line of human cancer cells. 28 proteins that are important for mitosis were made fluorescent mostly by CRISPR/Cas genome editing. These proteins were then tracked using 3D confocal microscopy, to see where in the cell they're located at each point in time. The microscope is so sensitive that it's even possible to count the proteins, so researchers know now if there are 100, 1000 or 10.000 proteins in a certain location. For all proteins, these data were integrated into an interactive computer model -- the creation of which was actually the largest part of the project. In total, there are about 600 different proteins involved in mitosis in human cells. Completing the dataset for all 600 would allow scientists to fully understand the transmission of information within a dividing cell, and how decisions -- like going from one cell cycle phase to the next -- are made. This will take several more years of work. "At EMBL, we're constantly adding information to the atlas by imaging more proteins in the same standardized way" says Stephanie Alexander, research manager in EMBL's Ellenberg group. "In the long run, a full overview of all the cell's proteins will allow us to see how different important processes of life, like cell division and cell death for example, are linked to one another. You can only understand this from a network point of view." Mitotic cell atlas: track proteins during cell division

Lagos, Nigeria (CNN)In one suburb of Dakar, Senegal's capital, every week, one person lands a sum of money that is tantamount to a jackpot. There's no gambling involved, however, the windfall comes from a savings system that has been popular in Africa for hundreds of years. Peer-to-peer savings circle are common on the continent, from Mali and Senegal where there are also known as 'tontines,' to Nigeria where it is called 'Ajo,' 'Esusu' or 'Adaji' depending on the local dialect. Each one has its own variations but the general way it works is that subscribers contribute a fixed sum to a common pot and take turns collecting the money after an agreed period. Some work on a weekly or monthly basis and the cycle continues until every member has taken from the pot. n Nigeria, as in Senegal, it is often used to fund businesses or large-scale projects while in Ethiopia, the 'Idir' serves as a form of insurance against special emergencies. Technology meets tradition While it is usually prevalent among female traders, many Africans take part in tontines schemes. They are a practical alternative in a region where more than half of the adult population does not use a formal monetary system. Now a new start-up, MaTontine, is trying to take the savings circle into the digital age, using mobile technology in Senegal. "The value of tontines in Senegal we estimate to be about $200 million per year," says Bernie Akporiaye, co-founder of MaTontine. "The problem is that money is not leveraged to provide significant services or value-added services that will get them out of poverty," The practice is highly successful because it is a great way for "poor people to save money," he tells CNN. MaTontine has created a system where technology meets tradition - paving the way for formal banking solutions. Mobile phones and mobile money replace the pots and designated members who collect the contributions. "What we have done is we have automated the whole process and able to deliver a range of financial services, whether it is small loans, whether they are micro-insurance products," Akporiaye says. Months after he launched, the platform has around a thousand members. One of them is Dieynaba Ly, who runs a small clothing store in Dakar and is using MaTontine's loans to grow her business. "Usually, when you go to any other banks, in order to be financed, they ask you to put down some collateral, which is not easy to get a hold of," "But MaTontine doesn't ask you for any of this," she says. Yet, for all the innovations, Akporiaye says the social cohesion that old tontines offer has restrained his company from starting new ones. "Instead we look for existing tontines and then we automate these tontines. Our innovation is to put together a credit scoring methodology so we can put credit scores or we can assign credit scores to the members and to the groups." MaTontine is hoping that it can count on this to bring digitized financial solutions across Africa. "We have one big hairy goal. We want to provide financial services to a million women in five years," he says.

The forthcoming Queen biopic will star 'Mr. Robot''s Rami Malek as the band's late frontman Freddie Mercury Bohemian Rhapsody, the upcoming Queen biopic, is set to premiere at Wembley Arena next month. The film, which will see Mr. Robot‘s Rami Malek portraying the band’s late frontman Freddie Mercury, is currently set for a UK release on October 24. It’ll chronicle the 15-year period between Queen’s formation as a band and their famous performance at Live Aid at Wembley Stadium in 1985. The premiere of Bohemian Rhapsody is set to take place a stone’s throw away from Wembley Stadium on October 23, with the film being screened at the SSE Arena. That venue is located next to the famous stadium, which re-opened in 2007 following extensive redevelopment which saw the original stadium (where Queen played that famous show) being demolished in 2003. Speaking about the significant location of the premiere – which is set to welcome 6200 guests for the screening – Fox U.K.’s managing director Chris Green said: “We’re delighted to be at The SSE Arena, Wembley giving Queen fans the chance to share in what is going to be a fantastic event. “The venue is perfect for showcasing the show-stopping performances in the film.” Malek is joined on the cast list of Bohemian Rhapsody by the likes of Mike Myers, Tom Hollander and Lucy Boynton. Last week, it was announced that audio tracks recorded at Queen’s 1985 Live Aid concert will be released for the first time as part of Bohemian Rhapsody‘s upcoming soundtrack release.

The plot thickens.. 50 Cent has entered the fray after a feud between Nicki Minaj and Cardi B emerged over the weekend. The pair reportedly came to blows at a New York Fashion Week party on Friday – with photos appearing to show Cardi being escorted out of the event. Now, 50 Cent has added his own reasoning to the feud after controversial rapper Tekashi 6x9ine and DJ SpinKing took their sides. In footage posted online, DJ SpinKing is seen playing Nicki’s music in a club – and Tekashi is seen dancing to it. But despite releasing ‘Fefe’ with Minaj, things suddenly go very different for Tekashi. At one point, the DJ stops the track and switches it to Cardi’s Bodak Yellow before saying: “I’m sorry Nicki, I’m team Cardi B on this side.” Tekashi is then seen dancing to Bodak Yellow – which is 50 Cent’s point of contention. He fears that the move could turn Tekashi against Minaj. “No @djspinking that’s female shit stay out of that, now Nicki gonna get mad at 69 for turning up, trust me”, the rapper warned in a since deleted Instagram post. “She on her South Side shit.” However, it ultimately seems that Tekashi’s actions didn’t come back to bite him – he was seen with Minaj last night. Meanwhile, the initial scuffle began after Cardi B supposedly approached Minaj over “lies Nicki was spreading”. Cardi B was allegedly elbowed in the face by a security guard before throwing a shoe at Minaj, who seemed to leave the incident unscathed. Minaj has not, as yet, released a statement about the incident. After Cardi was escorted out barefoot, a bump was visible above her eye. The incident was captured on video. In the video, Cardi B can be heard repeatedly shouting “b**** come here” at Minaj with security trying to break up the argument. Variety have also confirmed that the two people fighting were Cardi B

Miller passed away this weekend, aged 26 Liam Gallagher used his set at Lollapalooza Berlin to dedicate the Oasis classic ‘Live Forever’ to the memory of Mac Miller. See footage below. Miller, real name Malcolm McCormick, was found unresponsive at noon on September 7 at his San Fernando Valley home. Whilst no official cause of death has yet been released, Miller is believed to have died from an apparent overdose. Among the many figures to pay tribute to the rapper, Gallagher took to Twitter with the simple message ‘Mac Miller RIP x’. Fans then responded by re-sharing images of the various times the pair had met, as well as Mac Miller’s cover of ‘Wonderwall’. Speaking on stage at Lollapalooza Berlin this weekend to introduce ‘Live Forever’, Gallagher told the crowd: “I’d like to dedicate this to a lad who’s just died, Mac Miller”. Among the many artists to pay tribute to the young rapper, Miller’s friend Childish Gambino also used a performance this weekend to honour his memory. “I’m a very sensitive person… but this Mac Miller shit got me fucked up,” he said. “He was so nice. He was the sweetest guy, he was so nice. And we were both internet music kids, and a lot of critics were like, ‘This corny-ass white dude, this corny-ass black dude,’ and we used to talk. And this kid, he just loved music…my heart is broken.” Lil Xan also spoke of his devastation – adding that he was considering ‘retiring’ from music as a result. Miller was due to start a tour next month in support of his latest, critically acclaimed album, ‘Swimming’. He had also been profiled in Vulture earlier this week (September 6) where he spoke candidly about his struggles of growing up in the public eye. He said: “A lot of times in my life I’ve put this pressure to hold myself to the standard of whatever I thought I was supposed to be, or how I was supposed to be perceived. And it creates pressure.” Reviewing his latest album ‘Swimming’, NME called it “his best work in years” with the album receiving much critical acclaim elsewhere. There were reports that Miller was also planning an extensive collaboration with Post Malone. Born in Pittsburgh, Pennsylvania, Miller started making music while still at school. He released his first mixtape in 2007 under the name EZ Mac, aged just 15. He subsequently released five studio albums under his Mac Miller identity and collaborated with a multitude of artists.

Bowie & Queen like you've never heard it before... Foo Fighters unexpectedly gained two new members over the weekend, after the group invited a mum and daughter to perform. As they performed at Vancouver’s Rogers Arena on Saturday night, the rock titans were joined by ardent fan Maddy Duncan and her mum. The pair belted out Queen and David Bowie‘s ‘Under Pressure’, after the band noticed that Maddy was holding a sign that requested a duet. Footage posted on YouTube shows drummer Taylor Hawkins joining Maddy on the track, while her mum occasionally takes over on vocals.

"Life is so fucking fragile". G-Eazy became visibly overwhelmed as he paid tribute to Mac Miller, only hours after the rapper’s death was announced. The rapper paid tribute to Miller as he performed in Tampa on Friday night – becoming one of the first musical voices to pay tribute. “I swear, life is so fucking fragile,” he said during an emotional performance of ‘Everything Will Be OK’ at Tampa’s MidFlorida Credit Union Ampitheatre. “Appreciate the moment. Be present in it. Tell people you love you care about them.” Before the performance, he had paid tribute on Instagram – describing Miller as a “brother”. “Completely devastated and heart broken I’m at a loss for words mac you were like a brother to me and were there for me in the hardest of times, especially this summer,” he wrote on Instagram. “I can’t believe this is real. Please tell your friends and the people you care about you love them life is so fucking fragile. You will be missed and your music will live on forever through the millions of people you touched. Thank you for all you gave us, love you bro.” After the performance, he shared a photo of himself onstage – which featured Miller’s face on a giant screen. Miller, whose real name was Malcolm McCormick, was found unresponsive at noon on September 7 at his San Fernando Valley home. Whilst no official cause of death has yet been released, Miller is believed to have died from an apparent overdose.

"When your hero dies, fuck that shit". Lil Xan has opened up about the impact of losing his ‘hero’ Mac Miller. Miller, real name Malcolm McCormick, was found unresponsive at noon on September 7 at his San Fernando Valley home. Whilst no official cause of death has yet been released, Miller is believed to have died from an apparent overdose. Now in an interview for Adam22’s No Jumper podcast, Xan revealed his last encounter with Miller – and how his death has made him consider “retiring after this contract.” “The Mac shit is crazy,” he said, reports E. “I’ve been crying in my apartment, Mac didn’t die, Mac didn’t overdose.” “When your hero dies, fuck that shit, I don’t want to make music no more.” Speaking of their last meeting, he added: “Before I left, he was like ‘Be safe.’ People say that you know, like ‘be safe.’ But he grabbed me, and he pulled me back and he was like ‘No I mean BE SAFE,'” Lil Xan said. “That almost made me cry, that’s my idol right there.” “Malcolm McCormick, known and adored by fans as Mac Miller, has tragically passed away at the age of 26,” Miller’s family said in a statement. They added: “He was a bright light in this world for his family, friends and fans. Thank you for your prayers. Please respect our privacy. There are no further details as to the cause of his death at this time.” Miller’s former girlfriend Ariana Grande was also among those to pay tribute, by sharing a tender photo

All of his albums since 2000 have hit the top spot... Eminem has scored his ninth chart-topping album in the US, after surprise release ‘Kamikaze’ reached the peak of the Billboard 200 charts. The record, which was released on Aug. 31, scored 434,000 equivalent album units in the week ending Sept. 6. Of that amount, 252,000 were from traditional album sales. ‘Kamikaze”s chart showing is also stronger than that of Eminem’s last album, ‘Revival’, which debuted at No. 1 with 267,000 units on the chart dated Jan. 3, 2018. The achievement means that all of Eminem’s albums released since 2000 have hit the top spot. His only major release to miss the top was 1999’s The Slim Shady LP, which came in at number two. In the last week, some of rap’s most recognisable faces have responded after facing a call out from Eminem on the record – including Die Antwoord, Migos and Tyler The Creator. His address of the later courted controversy after he referred to Tyler as a “faggot”, prompting accusations of homophobia. He also picked a feud with Machine Gun Kelly – who duly responded with a diss track of his own. On ‘Rap Devil’, Machine Gun Kelly claims Eminem only came up with the track ‘Not Alike’ because he’s “sober and bored”. He also told him to get over a 2012 tweet that saw Kelly describing Eminem’s daughter Hailey as “hot as fuck”. “Still can’t cover up the fact the last four albums as bad as your selfie”, he raps. In response, D12 rapper Bizarre claimed that Eminem was recording a furious response to Kelly.

"We had four minutes and it was unbelievable." Bradley Cooper has spoken of his love for Glastonbury Festival, after he spent four days there filming A Star Is Born. The Oscar nominee, 43, surprised Glastonbury crowds in 2017 as he performed on the festival’s Pyramid Stage. He took to the stage moments before an appearance from country legend Kris Kristofferson. “Kris happened to be playing so I asked him if I could take up some of his set,” Cooper said of his Glastonbury appearance. “We had four minutes and it was unbelievable.” Describing the Glastonbury experience, he told press at the Toronto Film Festival: “I spent four days there in all and learned so much about its inner workings. “It’s the largest privately-owned music festival in the world and it is the place that makes and rejuvenates careers.” He added: “You watch major, huge musicians still get nervous about playing on the Pyramid Stage. “It’s still this place of fear and beauty.” A Star Is Born sees Cooper star alongside Lady Gaga in the story of two singer-songwriters who fall in love with each other, while their careers head in two entirely different trajectories. It debuted to huge critical acclaim at the Venice Film Festival last month, receiving an eight-minute standing ovation.

"It is all very, very charming". Elton John has reportedly secured a massive £5 million payday to star in the John Lewis Christmas advert for 2018. The music icon, 71, spent four days recording the advert at London’s Pinewood Studios. According to the Mail on Sunday, he’ll perform ‘Your Song’, with a storyline that spans Elton’s entire lifetime of Christmases. A source revealed: “John Lewis wanted to win the battle of the Christmas adverts this year and it has cost them a significant sum to do it, but they think having Elton on board will guarantee its popularity and blow Marks & Spencer out of the water. “It’s a tear-jerker but also very sweet, and follows Elton from a child, through his teenage years, into how he is today. “It is all very, very charming and the exciting crescendo at the end will be Elton playing his famous piano.” A John Lewis spokesperson responded: “We are lucky enough to enjoy lots of speculation around our TV ads, much of which is wildly inaccurate, and our one rule is to never comment on any aspect simply because we want to keep the magic.” Last year’s John Lewis advert featured the storyline of Mog The Monster, featuring an Elbow cover of The Beatles’ ‘Golden Slumber’. It was confirmed last week that Elton will begin the UK leg of his farewell tour in 2019, with stadiums shows in both Cardiff and Hove. A biopic of John’s life, directed by Bohemian Rhapsody‘s Dexter Fletcher, is set for release next May. The star will be portrayed by Taron Egerton.

What’s better than gaming for fun? Gaming for charity, that’s what, and our colleagues over Player2.net.au are gearing up for a massive gaming marathon to raise money for The Terry Campese Foundation. Last year Player 2 raised over $3500, and for this year’s event, it’s hoping to beat the $4000 mark, and to give a massive helping hand to underprivileged families in the Canberra and Southern NSW regions. “The chance to help out a charity such as Terry’s is an honour and a privilege” said Player 2 Editor, Matt Hewson, in a recent statement. “At Player 2, we often lament the lack of positive coverage our favourite hobby receives from mainstream media, so we feel it is our responsibility to lead by example.” So how can you help? The gaming marathon kicks off on the 15th of September at 10am, local time, and goes for a full 24 hours, with a new game played every hour - and you can following along on the Player 2 Twitch channel. And if you need a better reason to pitch in, every donation over $2 goes into a massive prize draw. There are game books, games - like Far Cry 5 and Nier Automata - and even a Pip-Boy 3000 to be won. There’s over 200 items, so they’re pretty good odds. You can learn more about the event at Player2.net.au .

Environmentalists have held protests around the world demanding stepped up measures against climate change, ahead of a summit in California next week. Politicians, business leaders and celebrities will attend the Global Climate Action Summit, whose sponsors include the UN, Facebook and Google. Thousands protested in Paris, days after France's environment minister quit over perceived policy failures. The demonstrations have been organised by the group 350.org. In all, more than 900 protests were held in 95 countries, the group said. On Friday, Pacific island nations declared climate change to be the "single biggest threat" they face. The protests began on Saturday with tall ships sailing into Sydney Harbour in Australia. Australia remains heavily reliant on coal to generate electricity, but activists say the country must join an international push towards renewable energy. In Bangkok, the capital of Thailand, environmentalists demonstrated outside a building where climate experts were discussing the 2015 Paris accord. The agreement commits nearly 200 countries to keeping rising global temperatures "well below" 2C above pre-industrial levels. Last year President Donald Trump announced the US would pull out of the deal, but this will not become effective until 2020 at the earliest. Environmental groups accuse the US of using UN talks to reduce the contributions of developed countries to the Green Climate Fund, which was set up to help countries deal with the effects of global warming. In Manila in the Philippines, demonstrators demanded an end to the funding of fossil fuel companies and more investment in renewable energies. German environmentalists protested outside the open-pit Tagebau Hambach coal mine in the west of the country. In France, where popular Environment Minister Nicolas Hulot quit in frustration last week, rallies were held in several cities, including Paris, Strasbourg and Marseille. Official estimates said 18,000 marched in Paris, but the demonstrations organisers said 50,000 attended. At a protest in downtown San Francisco in the US, signs made to look like solar panels were placed on pavements near the protest. Signs were emblazoned with slogans popular with Mr Trump's Democratic opponents, focusing on immigration and social justice.

Boris Johnson has attacked Theresa's May's Brexit plan, saying she had "wrapped a suicide vest" around the British constitution and "handed the detonator" to Brussels. Writing in the Mail on Sunday, the former foreign secretary said the Chequers deal had opened the UK to "perpetual political blackmail". Mr Johnson quit his post in July after the plan was agreed by the cabinet. Some Tory MPs have strongly criticised his language in the article. Writing in the same paper, the current Foreign Secretary Jeremy Hunt called on the country to "back" the prime minister and her plan. It is the first public comment from Mr Johnson since he and his wife, Marina Wheeler, confirmed they were getting divorced earlier this week. The announcement followed newspaper allegations the former London mayor had been having an extra-marital affair. In 2004, Mr Johnson was sacked from a shadow ministerial role by then-Conservative leader Michael Howard for allegedly lying over an affair with journalist Petronella Wyatt - something he had denied as an "inverted pyramid of piffle". Elsewhere, the Sunday Times has reported that Mrs May's aides wrote a 4,000-word "dirty dossier" on Mr Johnson in 2016, exposing a "catalogue of lurid allegations" against him. The paper says it has seen the document - said to have been written during the Conservative leadership contest - but officials at Downing Street and Conservative Campaign Headquarters have denied circulating it. And trade union leaders are warning time is running out to secure a Brexit deal. Trades Union Congress general secretary Frances O'Grady urged Mrs May to put the good of the country ahead of the interests of her own party in negotiations with the EU. As the TUC conference gets under way in Manchester, the People's Vote Campaign - which wants another EU referendum on the final Brexit deal - has published polling suggesting a majority of union members support their demands. = In his newspaper article, Mr Johnson accused the EU of "bullying" the UK - but questioned why the response had been "so utterly feeble". He said that rather than getting a "generous free trade deal", Britain is saying, "yes sir, no sir, three bags full sir", to Brussels. "At every stage of the talks so far, Brussels gets what Brussels wants," wrote Mr Johnson. "It is a humiliation. We look like a seven-stone weakling being comically bent out of shape by a 500lb gorilla." He said the reason for this was "simple", namely Northern Ireland and the "insanity of the so-called backstop". The backstop solution is a safety net the UK and EU signed up to in December 2017, which seeks to maintain cross-border co-operation, support the all-island economy and protect the Good Friday peace agreement. Mr Johnson said agreeing to this had "opened ourselves to perpetual political blackmail". He added: "We have wrapped a suicide vest around the British constitution - and handed the detonator to Michel Barnier [the EU's chief negotiator]." Mr Johnson wants the UK to pursue a technological solution for the border, but says the government has always had a "secret agenda" to keep the UK in the single market and customs union. He concluded: "We have put our own heads deliberately on the block." The BBC's political correspondent Alex Forsyth said the "scathing remarks" showed Mr Johnson's "willingness to challenge the prime minister remains undimmed" after the recent revelations about his private life. It is Mr Johnson's second attack on the prime minister's Brexit strategy inside a week, as last Monday he used his Daily Telegraph column to say the Chequers deal "means disaster" for Britain. Mr Johnson's latest intervention has been criticised by two senior Conservative MPs. Former Army officer and member of the Foreign Affairs Select Committee Tom Tugendhat graphically described the aftermath of a suicide bomb that had gone off near his office in Helmand province, Afghanistan. He said comparing such an attack to the PM's plans "isn't funny", adding: "Some need to grow up". Foreign Office minister Sir Alan Duncan criticised his former boss, saying the article was "one of the most disgusting moments in modern British politics." If this latest broadside was not the end of Mr Johnson's political career, "I will make sure it is later", he said. Mr Hunt expressed his support for Mrs May and the Chequers deal in the newspaper on the opposite page from Mr Johnson's article. He wrote that the PM was "better than anyone I know at holding the line in the face of intense pressure". But he called on the country to "unite behind her" to strengthen her position. "Parliament will, of course, have the chance to debate and vote on any agreement. Until then, we should not rush to judgement on a deal that is still under negotiation."
