New generations of PCI Express tech—the interface used across PC parts—are already on the way.

Many of us look to the stars for answers to life’s most complex questions. But actually, some of the greatest mysteries lie beneath our very feet. One might think we’d know the Earth pretty well by now but, in fact, our planet’s core remains shrouded in enigma. Indeed, there are two gigantic blobs located beneath Africa and the Pacific Ocean that occupy around six per cent of the world’s entire volume. And yet, we’re still not entirely sure what they’re made of or where they came from. There are a number of hypotheses, including that they are piles of oceanic crust that have accumulated over billions of years.

To give an indication of just how massive these things are, the structure under Africa – an area known as Tuzo – is thought to be around 800km (497 miles) tall – the equivalent of some 90 Mount Everests stacked on top of one another, as IFLScience notes. The problem with determining the origin of these monster formations is that there are no direct ways of observing the Earth’s core. The deepest hole humans have ever dug – branded the "entrance to hell" – reached a pretty staggering 12,263m (40,230ft), but that doesn’t even come close to breaking through the crust to the layers beneath. Our most effective tool for analysing what lies beneath the ground is a technique called seismic tomography, which looks at how waves of energy travel when earthquakes occur. Since rocks and liquids have different densities, the waves move through them at different speeds. By measuring the tremors from different points on the surface, geologists can determine what kind of material the waves are travelling through and, in so doing, map out the Earth’s interior. It was by using this technique that the two unusual structures – known as large low shear velocity provinces (LLSVPs) – were found. Waves travel more slowly in these areas – fondly known as “blobs” – than through the surrounding lower mantle, indicating that they’re made of something different. We can’t tell what this material is based on seismic tomography data alone, but some scientists like to believe that they are the remnants of an ancient planet called Theia – an idea known as the “giant impact hypothesis”. According to this hypothesis, around 4.5 billion years ago, a Mars-sized object collided with the Earth. This impact not only created the planet we call home today, but also threw off enough rock to form the moon that lights up our night skies. Some scientists suggest that some of Theia’s leftovers also sunk to the bottom of the planet, probably settling somewhere above the core – thereby forming at least one of the two LLSVPs. More Updates About Strange Blob Structures Inside Planet Earth youtu.be Experts have been investigating the area for decades but there’s still no way of knowing for sure just what these two giant blobs are. Still, studies into Theia have offered important insights into how the possible collision might have kickstarted key plate tectonic and mantle motion inside our planet – crucial processes for establishing the world on which we live. It’s also a useful reminder that we still have so much to learn about our planet and where we came from. Have your say in our news democracy.

Apple is working on a “Watch X”, bring a major redesign and new features to its wearable, according to a new report. The new version will be thinner, bring new health features such as a blood pressure sensor and change the technology powering the screen, according to a new report from Bloomberg’s Mark Gurman. But the new version of the Watch might not arrive until next year, or even the year after that, he reported. As such, the new design would mark the 10th anniversary of the Watch, which went on sale in April 2015. Apple undertook a similar significant redesign for the 10th version of the iPhone, with the iPhone X. That also brought a new look, with a slimmer design and a display that wrapped all the way to the edge of the phone, and new technologies such as facial recognition. This year’s Apple Watch is expected to bring a new processor, which would be the first since 2020’s Series 6. Otherwise, it is expected to stay largely the same on the outside. That might give Apple more time to work on that rumoured “Apple Watch X”, for the years that would follow. As well as the new redesign and features, it might rely on a microLED screen that has not yet been seen in the Apple Watch. Apple has long been rumoured to be working on such screen technology for the Watch, to bring the brighter and more colourful screen technology to the small display. Rumours have suggested however that the company has struggled with the new technology, and hit problems with shrinking it down to the size of the Watch and allowing it to stay affordable. The other major feature update is said to be a blood pressure built into the Watch itself. Chief executive Tim Cook has repeatedly said that health is one of the big focuses of Apple’s work, and has been rumoured to be working on new sensors including blood glucose and blood pressure, presumably for its wearables. The redesign could have some drawbacks. The redesign will bring with it a new, magnetic way of attaching watchbands – which would presumably mean that existing Watch straps will not work with the Watch X. Until now, all versions of the Watch have been compatible with all of Apple’s straps, as long as they are the correct one of two sizes. Mr Gurman did suggest on Twitter that Apple or third-party manufacturers could create adapters to allow old straps to work on new Watches.

About 20 per cent of US academic respondents in a survey have reported that they, or someone they know, have seen unidentified flying objects (UFOs). Over a third of the nearly 1,500 respondents are interested in conducting research into such unidentified aerial phenomena (UAP), suggested the results of the survey, published in the journal Humanities and Social Science Communications. The US government has undertaken new hearings, reports and investigations into UAP, with a report by the Pentagon suggesting there were over 500 reports about UFOs with the agency as of August 2022. In the current research, scientists, including those from the University of Louisville, surveyed 39,984 academics, including professors, associate professors and assistant professors from 144 US universities across 14 different disciplines. Despite the stigma associated with the topic, researchers said these developments merit asking university faculty about their perceptions on the sightings of UFOs. Researchers asked the 4 per cent of individuals who responded to the survey about their perceptions of, experiences with and opinions of UAP. Nearly a tenth of the participants worked in political science, another tenth in physics, 10 per cent in psychology and 6 per cent in engineering. About 276 of the respondents – or 19 per cent of participants – reported that they or someone they knew had witnessed UAP. A further 9 per cent said they or someone they knew “may have witnessed” UAP, according to the study. Thirty-nine percent of all the participants said they did not know what the most likely explanations for UAP were, but a fifth of them attributed the sightings to natural events and 13 per cent to devices of unknown intelligence. About 4 per cent of participants said they had conducted academic research related to UAP, and over a third said they had some degree of interest in conducting research in this area. Among the respondents, 37 per cent ranked the importance of further research into UAP as either “very important” or “absolutely essential”, while nearly two-thirds of them considered academia’s involvement in UAP-related research to be “very important or absolutely essential”. The findings hinted that many American academics across disciplines consider academia’s involvement in research into UAP to be important. “Results demonstrated that faculty think the academic evaluation of UAP information and more academic research on this topic is important,” scientists wrote in the study, adding that curiosity on the topic “outweighed scepticism or indifference”. Researchers also suggested many may be cautiously willing to engage with UFO research if others they consider to be reputable within their field also do so. However, they said more surveys among larger and diverse cohorts are needed to understand attitudes of academics towards UAP.
