Apple has unveiled its first-ever augmented reality headset, and it's giving people the creeps over how futuristic it is. The headset has a two-hour battery life, and will cost $3,499 (£2,849), when it's released next year. Functionality includes watching TV, being able to use your favourite apps in a 3D setting, FaceTime calls, and using a keyboard, with CEO Tim Cook saying it's the ultimate way to 'blend the digital and virtual' worlds. However, fans have been quick to point out it looks like the start of a Black Mirror episode. Click here to sign up for our newsletters

Social media can be a nasty place at times, but every now and then a trend comes along which reminds you just how fun it can be. The most recent is the blue couch, which has been the talk of Twitter for the past week or so. In case you missed it, influencer Amanda Joy got a lot of people talking recently after finding a couch abandoned on the streets of New York. After doing a little research and believing it to be the $8,000 ‘Bubble’ couch from French brand Roche Bobois, she decided to take it back to her apartment and clean it up. Sign up to our free Indy100 weekly newsletter Joy’s dad picked up the couch in his van and Joy filmed the entire process of brightening up the sofa and moving it to her living room. The TikTok now has over 40 million views, and over 4 million likes – but not everyone thought it was a good idea to take the couch off the sidewalk. Some believed the unique-looking piece wasn’t the real deal and instead claimed it was a knockoff. Others were concerned about possible bed bugs and roach infestations, with no sign of how long the couch had been on the street. In the days that followed it continued to raise eyebrows across the internet, and these are some of the biggest reactions and memes. Have your say in our news democracy.

Vice President Kamala Harris has been left somewhat red-faced after a clip of her attempting to explain artificial intelligence was viewed more than 800,000 times. Ms Harris describing AI as a “fancy thing” during a roundtable with advocacy representatives has been roundly mocked, with many people comparing the answer to some of the gaffes that President Joe Biden has become known for. “I think the first part of this issue that should be articulated is AI is kind of a fancy thing, first of all, it’s two letters, it means artificial intelligence but ultimately ... it’s about machine learning,” Ms Harris said. “And so the machine is taught and part of the issue here is what information is going into the machine that will then determine, and we can predict then if we think about what information is going in, what then will be produced in terms of decisions and opinions that may be made through that process.” One Twitter user referred to Ms Harris’ description as being like “the introduction to a 6th-grade essay on AI”, while another suggested the vice president “always speaks as if she is talking to a room of 3rd graders”. “It’s nearly impossible to tell the difference between Kamala Harris speaking about AI and Bart Simpson’s book report on Treasure Island,” another user added. Ms Harris has previously been mocked for past comments, in particular after she told Today in January 2022 on the topic of the coronavirus pandemic: “It is time for us to do what we have been doing, and that time is every day. Every day, it is time for us to agree that there are things and tools that are available to us to slow this thing down.” The vice president currently has an approval rating of 39.2 per cent, according to polling averages from FiveThirtyEight, while President Biden has a slightly higher approval rating of 40.6 per cent.

The Mona Lisa has been the subject of awe and fascination for centuries, with experts from around the world desperate to solve the mystery behind her iconic, enigmatic smile. Now, thanks to X-ray technology, scientists have begun to uncover the secrets of Leonardo da Vinci’s legendary portrait, and explain how he was able to create something so mind-bending with just a few strokes of a brush. The research, published in the Journal of the American Chemical Society on Wednesday, suggests that the Italian Renaissance master may have been in a particularly inventive mood when set about crafting the piece in the early 16th century. "He was someone who loved to experiment, and each of his paintings is completely different technically," Victor Gonzalez, the study's lead author, told the Associated Press.. Gonzalez, who has studied the chemical compositions of dozens of works by Leonardo and other artists, discovered that there was something special about the paint used for the Mona Lisa. Specifically, the researchers found a rare compound, called plumbonacrite, in Leonardo's first layer of paint. The discovery confirmed that Leonardo most likely used lead oxide powder to thicken and help dry his paint as he began working on the portrait. He is thought to have dried the powder, which has an orange colour, in linseed or walnut oil by heating the mixture to make a thicker, faster-drying paste. "What you will obtain is an oil that has a very nice golden colour," Gonzalez said. "It flows more like honey." Carmen Bambach, a specialist in Italian art and curator at New York's Metropolitan Museum of Art, who was not involved in the study, called the research "very exciting". She emphasised that any scientifically proven new insights into Leonardo's painting techniques are "extremely important news for the art world and our larger global society." Finding plumbonacrite in the Mona Lisa attests "to Leonardo's spirit of passionate and constant experimentation as a painter—it is what renders him timeless and modern," Bambach said. The paint fragment Gonzalez and his team analysed for their study was taken from the base layer of the painting and was barely visible to the naked eye. It was no larger than the diameter of a human hair, and came from the top right-hand edge of the picture that now takes pride of place in Paris’s Louvre Museum. The scientists peered into the sample’s atomic structure using X-rays in a synchrotron – a large machine that accelerates particles to almost the speed of light. This allowed them to unravel the speck's chemical makeup and detect the plumbonacrite. The compound is a byproduct of lead oxide, allowing the researchers to say with more certainty that Leonardo likely used the powder in his paint recipe. "Plumbonacrite is really a fingerprint of his recipe," Gonzalez said. "It's the first time we can actually chemically confirm it." After Leonardo, Dutch master Rembrandt may have used a similar recipe when he was painting in the 17th century; Gonzalez and other researchers have previously found plumbonacrite in his work, too. "It tells us also that those recipes were passed on for centuries," Gonzalez said. "It was a very good recipe." Still, the ‘Mona Lisa’—said by the Louvre to be a portrait of Lisa Gherardini, the wife of a Florentine silk merchant—and other works by Leonardo still have other secrets to tell. "There are plenty, plenty more things to discover, for sure,” Gonzalez said. “We are barely scratching the surface.” Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.
