A researcher has figured out that the Earth’s first continent was formed 3bn years ago, in a new paper that sheds fresh light on the early stages of the planet’s life. Jane Greaves, an astronomy professor in the School of Physics and Astronomy at Cardiff University in Wales, was examining continent formation on distant stars and planets. It is thought that exoplanets with continents that formed in a similar way to Earth’s are more likely to be habitable, and perhaps even contain alien life. In the process, she calculated when several distant planets’ continents were born, as well as those a little closer to home. Continents on Earth sit on top of the planet’s hot, viscous mantle. Heat from the inner core stops the mantle from solidifying. The reason the core is hot is because it contains radioactive elements that came from neutron star collisions billions of years ago such as forms of Uranium, Thorium and Potassium. By analysing how many materials like this are present on Earth and on other planets, we are also able to estimate when the continents formed. On Earth, that was about 9.5 billion years since the beginning of the universe. Meanwhile, in Greaves' sample, the first continents appeared 2bn years before Earth’s on the exoplanets of younger, so-called thin disk stars. Older, thick disk stars analysed in her work produced rocky planets with continents that appeared even earlier: about 4 to 5bn years before Earth’s. “The outlook seems very promising for finding rocky exoplanets with continents, given that nearby Sun-like stars have already produced a few candidate hosts,” she wrote.

Apple Inc.’s major suppliers in Taiwan suffered another double-digit sales decline in August as weak consumer demand dragged

Apple employees in France plan to walk out this weekend during the launch of the iPhone 15 following a disagreement about pay and working conditions. Apple retail unions, which include CGT, Unsa, CFDT and Cidre-CFTC, are demanding a 7 per cent wage increase to compensate for inflation, however Apple have reportedly only offered a 4.5 per cent pay increase. The release of the iPhone 15 is the biggest product launch of the year for the US tech giant. Apple France did not return a request for comment. “Management having decided to ignore our perfectly legitimate demands and concerns, the four unions of Apple Retail France... call for a strike on 22-23 September,” CGT Apple Retail said in a statement on social media platform X, formerly Twitter, on Wednesday. It added that representatives of Apple France’s corporate division and Apple’s Barcelona team in Spain also called for a strike. The unions called for workers to demonstrate on Friday morning at Opera Garnier, next to Apple’s flagship Paris store. A CGT Apple Retail union official said the call for a strike had been sent to Apple’s 20 French stores. Apple has nine stores in the Paris region, including three in central Paris, and two in Lyon. Other cities with Apple stores include Marseille, Lille and Strasbourg. “On Tuesday we had a teleconference meeting with Apple’s European bosses. They basically said ‘you are doing pretty well, do not complain,’” the CGT official said. Last week, Apple was rocked by a French government decision to suspend sales of iPhone 12 handsets after tests which it said found breaches of radiation exposure limits. On Friday, Apple pledged to update software on iPhone 12 devices in France in an effort to settle the dispute. Similar action may also be required in other European countries after regulators from Germany and the Netherlands both expressed concerns about the radiation levels.

Scientists in Mexico have given their verdict on the supposed 'aliens' that were presented to the country's congress last week. Much controversy existed around the aliens who were presented by a man named Jaime Maussan who has previously been accused of using the mummified beings, apparently found in Peru, as part of an elaborate hoax. Despite spawning dozens of memes, the aliens are apparently being treated seriously enough that they have now been studied by scientists who have said that the figures are ‘single skeletons’ and also have 'eggs' inside of them. The two aliens have been named Clara and Mauricio and have reportedly been studied in a lab at the Noor Clinic in Mexico. Lead researcher Dr Jose de Jesus Zalce Benitez, a former navy forensics doctor, who added that as well as being "a single skeleton" the aliens are also a "complete organic being." He also denied that the aliens were part of a hoax and even said that Clara was "alive, was intact, was biological and was in gestation." However, much like the alien bodies themselves, the research has been clouded in controversy and scepticism as the research has yet to be officially verified, with Nasa scientist Dr David Spergel questioning why the findings haven't been made public, as per the BBC. Spergel said: "He said: "If you have something strange, make samples available to the world scientific community and we'll see what's there." Benitez did add in his address at the press conference: "We are facing the paradigm of describing a new species or given the opportunity to accept that there has been contact with other beings, non-humans, that were drawn and marked in the past by diverse cultures throughout the world."

Google says it has made a significant step in identifying disease-causing genes, which could help spot rare genetic disorders. A new model named AlphaMissense is able to confidently classify 89 per cent of all possible “missense” variants in genes, identifying whether they are likely to cause diseases or benign. That compares with just 0.1 per cent of all missense variants that have been confidently classified by human experts. Missense variants happen when a single letter is substituted in the DNA, which in turn leads to proteins with a different amino acid. That small change can have significant effects – Google likened it to the way that changing a letter in one word can change the meaning of the whole sentence. Most of those variants are benign: the average person has more than 9,000 of them. But some of them can be disastrous, leading to rare genetic diseases. The new AlphaMissense looked at existing information about missense variants, and how commonly they are seen in humans and closely-related primates. It looked for those that were rarely seen, classifying them as pathogenic, and from that was able to use that information to analyse other protein sequences – giving not just a verdict on whether they were likely to cause problems, but also how confident it was. Experiments, conducted by humans, which look to find those mutations are expensive and slow: they require people to examine each unique protein and designed separately. Google says that the new system means that researchers can “preview” those results for thousands of proteins at a time, helping them decide where to focus. The company has used its systems to release a vast catalogue of “missense” mutations, so that researchers can learn about what effect they have. In some cases, those variations can lead to conditions such as cystic fibrosis, sickle-cell anaemia, or cancer, and understanding them could be key to researchers studying ways to treat or prevent those diseases. It is just the latest health breakthrough from Google’s Deepmind division, which is looking to use artificial intelligence to both identify and treat a variety of conditions. The new system was built on AlphaFold, the breakthrough model that helped unfold proteins, the building blocks of life. The research is described in a new paper, ‘Accurate proteome-wide missense variant effect prediction with AlphaMissense’, published in the journal Science. The catalogue is being made “freely available to the research community”, Google said, and the company will release the code behind the AI system.

A Vatican astronomer has come to the help of NASA with a historic mission to study an asteroid. Meteorite expert and Vatican astronomer, Jesuit Brother Bob Macke, came to the aid of the US space agency after building a custom device that would allow the study of material of a sample collected from an asteroid. The mission is that of the unmanned spacecraft, Osiris-Rex, which was launched in 2016 in order to collect samples on an asteroid named Bennu. Bennu is located close to Earth and Osiris-Rex successfully collected a cup of material from the asteroid in 2020. Now, the vessel is approaching Earth and is due to release the sample in a return capsule on 24 September before continuing its orbit of the sun. Macke was contacted by the lead of the mission’s sample analysis working group, Andrew Ryan, who asked him to build the device that was needed in order to analyse the sample of the Bennu asteroid. The device has been devised so that it can analyse the density and porosity of the samples to help identify the make up of the asteroid surface. It is known as a pycnometer and NASA has strict requirements for the device, though other companies contacted were not willing to custom make one. Macke, however, took up the task and was able to build it in five weeks thanks to the assistance of students at the University of Arizona who collaborate with the Vatican Observatory’s advanced technology telescope in Tucson. In March it was delivered to the NASA Johnson Space Center in Houston for a test run and is hoped to be used for the real thing when the sample arrives from space.

Conspiracy theorists have been turning their attention to Antarctica more than you’d expect over recent years. First, there was the case of the “bleeding waterfalls”, which remains one of the strangest natural phenomena you're likely to see, and there’s also the mystery of a so-called “pyramid” which has been found on the continent. Only, it’s not a pyramid at all – in fact, it’s a mountain. The Ellsworth Mountains are the highest mountain range in Antarctica and stretch 400km and the mountain in question was discovered by the British Antarctic Expedition of 1910-1913 It was called “The Pyramid” to keep the true nature of the discovery hidden from others at the time. Over the last hundred years, however, people have been speculating about the true nature of the location (even though it’s very much a mountain, poking up out of the ice) and now a second interesting geographical feature has bee discovered and got them talking all over again. The location in question is found at the coordinates 79°58’39.25?S 81°57’32.21?W, which has been a much-searched spot on Google Earth. Speaking to IFL Science, geologist at the German Research Centre for Geosciences in Potsdam, Dr Mitch Darcy, said: “The pyramid-shaped structures are located in the Ellsworth Mountains, which is a range more than 400 km long, so it’s no surprise there are rocky peaks cropping out above the ice. The peaks are clearly composed of rock, and it’s a coincidence that this particular peak has that shape. “It’s not a complicated shape, so it’s not a special coincidence either. By definition, it is a nunatak, which is simply a peak of rock sticking out above a glacier or an ice sheet. This one has the shape of a pyramid, but that doesn’t make it a human construction.” So, the new location is just that – a mountain poking out the top of the ice in Antarctica, and not a mysterious pyramid at all. Antarctica has been the subject of more than its fair share of speculation recently, after conspiracy theorist Eric Hecker described the Amundsen–Scott South Pole Station by the south pole as an “air traffic control” hub for aliens earlier this year. Hecker claimed that in 2010 Raytheon, the US aerospace and defence conglomerate chose him to be a contractor on the research centre operated by the United States National Science Foundation. There was “much more” to the station that first met the eye, according to Hecker. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
