NASA has lifted the lid on its first findings about the Bennu sample, one of the "most hazardous known asteroids". The highly-anticipated sample from the OSIRIS-REx’s mission took seven years to complete and finally made a safe landing on Sunday 24 September. Scientists audibly gasped upon opening the capsule. They kept details to a minimum and maintained a slow pace in progress for "good reason," as they received more material than expected. "The abundance of material found when the science canister lid was removed earlier this week has meant that the process of disassembling the TAGSAM (Touch-and-Go Sample Acquisition Mechanism) head – which holds the bulk of material from the asteroid – is off to a methodical start," they said a the time. That was until now... On Wednesday 11 October, the space agency shared details for the first time from NASA experts and the University of Arizona. NASA said there were signs of water and carbon on the sample through hydrated clay minerals that contain carbon. "At nearly 5% carbon by weight, carbon being the central element of life, far exceeding our goal of 60g, this is the biggest carbon-rich asteroid sample ever returned to earth," Administrator Bill Nelson said, adding that it was "exactly the kind of material that we wanted to find." He went on to suggest that "they are going to help us determine the origin of elements that could have led to life" and provide a greater understanding of how to protect Earth from asteroids. Scientists also revealed that the sample contained space dust from asteroid Bennu. NASA showed the audience the sample on a video to protect the sample and to prevent contamination. Speaking about working through a glove box to analyse the sample, Francis McCubbin, astronomical curator at NASA's Johnson Space Centre said: "[It is] "hard, challenging work, and it does not go quickly, but we need to do this right". The samples will be preserved so that "scientists that aren't even born yet are going to have the opportunity to answer questions about our universe with these samples using technology that has not even been invented."

Yamaha has unveiled a self-riding electric motorbike that features no handlebars or other standard controls. The Yamaha Motoroid 2 is the next generation of the firm’s Motoroid concept bike first revealed in 2017, but unlike its predecessor, Yamaha has built a working prototype of the latest vehicle. The self-balancing bike features gyroscopes and image recognition AI systems to stay upright and navigate roads, while also being capable of riding itself without anyone aboard. “Motoroid 2 is a vehicle for personal mobility that can recognise its owner, get up off its kickstand and move alongside its rider,” the company said. “[It] has a distinctly lifelike feel when somebody is riding on its back and has a presence more like a lifetime companion.” Yamaha plans to show off the prototype of the Motoroid 2 at the Events Japan Mobility Show 2023 in Tokyo next month. It is not clear whether Yamaha plans to release a production model of the bike, however its continued development suggests that the automotive giant is working to integrate at least some of its features into future motorcycles. Self-driving technology is increasingly common in production vehicles, though it is currently limited to four-wheeled cars and trucks. Some have even considered eschewing steering wheels, with Tesla chief executive Elon Musk originally planning to build a fleet of self-driving electric taxis that have no visible user controls. The plan was reportedly sidelined after company executives noted that regulators in most major markets require steering wheels and pedals on vehicles. Several motorcycle manufacturers have unveiled concept bikes that require no rider to operate. BMW’s ConnectedRide retrofits the company’s R 1200 GS Adventure with autonomous technology to serve as a “testbed for advanced motorcycle safety” equipment that it hopes to introduce to its production models. “In a future world of autonomously driving cars, being connected will be an urgent requirement for all motorcycle segments,” BMW’s Markus Schramm said in 2020. “This will enhance safety and ensure that motorcycling remains future-proof.” Read More Reinventing the seatbelt for the self-driving era

Mysterious blasts coming from deep in space could be the result of “starquakes”, according to a new study. For years, scientists have been observing fast radio bursts, or FRBs, coming from distant parts of space. They are very intense, very short blasts of energy – and despite finding many of them, researchers still do not know where they are coming from or how they might be formed. Now, scientists have spotted that there is appears to be similarities between those FRBs and earthquakes. Researchers behind the new study suggest that the blasts could be the result of similar behaviour on neutron stars, known as starquakes. It is just one possible explanation for the unusual bursts, which have led to suggestions they could be anything from neutron stars colliding with black holes to alien technology. Most have settled on the belief that at least some of those FRBs come from neutron stars, however, which are formed when supergiant stars collapse into an incredibly dense, small object. In the new study, researchers looked at data from nearly 7,000 bursts, taken from three different sources that are sending out repeated FRBs, examining the time and energy that they emerged in. They then also looked at earthquake information taken from Japan, and data on solar flares, and looked to compare the three. There was little connection between FRBs and solar flares, the researchers found. But there was a striking similarity between the blasts and earthquakes. “The results show notable similarities between FRBs and earthquakes in the following ways: First, the probability of an aftershock occurring for a single event is 10-50%; second, the aftershock occurrence rate decreases with time, as a power of time; third, the aftershock rate is always constant even if the FRB-earthquake activity (mean rate) changes significantly; and fourth, there is no correlation between the energies of the main shock and its aftershock,” said Tomonori Totani from the University of Tokyo, one of the leaders of the study. The findings have led scientists to speculate that there is a solid crust on the outer surface of neutron stars. That crust then experiences starquakes in the same way the Earth’s surface does – and those quakes then let out powerful blasts of energy that make their way to us as FRBs. But researchers say they will need to further examine those FRBs to better understand the connection between the two – as well as to help give us information about quakes and other physical phenomena that are closer to home. “By studying starquakes on distant ultradense stars, which are completely different environments from Earth, we may gain new insights into earthquakes,” said Professor Totani. “The interior of a neutron star is the densest place in the universe, comparable to that of the interior of an atomic nucleus. “Starquakes in neutron stars have opened up the possibility of gaining new insights into very high-density matter and the fundamental laws of nuclear physics.” The research is described in a new paper, ‘Fast radio bursts trigger aftershocks resembling earthquakes, but not solar flares’, published in the journal Monthly Notices of the Royal Astronomical Society.

“The Matrix is everywhere. It is all around us. Even now in this very room." So says Laurence Fishburne’s Morpheus in sci-fi classic ‘The Matrix’ as he offers Keanu Reeves’s Neo the choice to find out just how “deep the rabbit hole goes”. Now, just as Neo discovered that the "life" he'd been living was little more than an algorithmic construct, scientists and philosophers are arguing that we could be stuck inside a simulation ourselves. In a paper published earlier this month, physicist Melvin Vopson, of the University of Portsmouth, offered scientific evidence for a philosophical theory known as the simulation hypothesis. This, in a nutshell, posits that the entire universe and our objective reality are just super-advanced virtual reality illusions. Elon Musk is among the well-known fans of the theory, which – as Dr Vopson notes in his paper – has been “gaining traction in scientific circles as well as in the entertainment industry”. The university lecturer also pointed out that recent developments in a branch of science known as information physics “appear to support this possibility”. Information physics suggests that physical reality is fundamentally made up of bits of information. However, Dr Vopson has gone further and is working to prove that information has a physical mass and is a fundamental building block of the universe. He even claims that information could be the mysterious dark matter that makes up almost a third of the universe. In previous research, the physicist proposed that all elementary particles (the smallest known building blocks in the universe), store information about themselves, much like DNA in humans. Then, in 2022, he discovered a new law of physics, christened the second law of infodynamics, which states that entropy – the degree of randomness or disorder – within an isolated information system either remains constant or decreases over time. In other words, the system becomes less and less chaotic, implying that there is some kind of mechanism governing it rather than random chance. “I knew then that this revelation had far-reaching implications across various scientific disciplines,” Dr Vopson said in a statement released by the University of Portsmouth. “What I wanted to do next is put the law to the test and see if it could further support the simulation hypothesis by moving it on from the philosophical realm to mainstream science.” Is the Universe a Simulation? | Melvin Vopson www.youtube.com Dr Vopson employed the law in a range of different fields, including genetics, cosmology and even symmetry. Here, he found that the abundance of symmetry in the Universe (think snowflakes and facial structures) could be explained by the second law of infodynamics. "Symmetry principles play an important role with respect to the laws of nature, but until now there has been little explanation as to why that could be,” he said. “My findings demonstrate that high symmetry corresponds to the lowest information entropy state, potentially explaining nature's inclination towards it." Again, put simply, nature prefers things to be as well-ordered as possible. He continued: “This approach, where excess information is removed, resembles the process of a computer deleting or compressing waste code to save storage space and optimise power consumption.” As a result, this “supports the idea that we’re living in a simulation.” Dr Vopson is serious about this idea and, last year, even launched a crowdfunding campaign to test it. At the time, he announced that he had designed an experiment to determine whether we are all just characters in an advanced virtual world. “There is a growing community out there looking seriously at the possibility that information is more fundamental to everything than we think,” he said in a statement released back in December. “If information is a key component of everything in the universe, it would make sense that a vast computer somewhere is in control. “Assuming the universe is indeed a simulation, then it must contain a lot of information bits hidden everywhere around us. I’ve devised an experiment that proposes a way of extracting this information to prove it’s there.” His proposed experiment is based on his conclusion that information is physical and that elementary particles have a DNA of information about themselves. He posited that the information in an elementary particle could be detected and measured by using particle-antiparticle collision. “We can measure the information content of a particle by erasing it. If we delete the information from the particles, we can then look at what’s left,” he said in the December statement. “This experiment is highly achievable with our existing tools, and I’m hoping the crowdfunding site will help us achieve it.” And whilst the crowdfunder closed well before reaching its proposed £185,000 target, Dr Vopson still hopes to carry out the ambitious test. Following his most recent paper, he suggested the experiment had the power to confirm the “fifth state of matter in the universe” and “change physics as we know it.” Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Ebay is facing a fine of nearly $2 billion for allegedly enabling the sale of ‘rolling coal’ devices and other deliberately polluting equipment that violates environmental laws. The US Department of Justice alleges that the online retailer sold more than 343,000 so-called defeat devices in violation of the Clean Air Act, with each sale the subject of a $5,580 fine. Rolling coal has become a form of anti-environmentalism protest in the United States, involving the modification of a diesel engine in order to emit black clouds of sooty exhaust fumes. Online video compilations show drivers of pickup trucks deliberately rolling coal as they pass cyclists and electric vehicles. Until recently, the devices required to perform it were relatively easy to find through online retailers, costing between $200-500. The Justice Department wrote in its complaint, which was filed on behalf of the Environmental Protection Agency (EPA) in a federal court in New York, that the rolling coal devices “defeat motor vehicle emission controls” set out in the Clean Air Act. “Aftermarket defeat devices significantly increase pollution emissions – including carbon monoxide, nitrogen oxides, particulate matter and nonmethane hydrocarbons – that harm public health,” the complaint stated. The EPA criminalised the practice, which appears to be mainly confined to the US, in 2014, with some states warning of fines of up to $5,000 for anyone caught doing it. Several companies who sell coal rolling equipment have already been forced to pay fines of up to $1 million for breaking the law. “Our nation’s environmental laws protect public health and the environment by prohibiting the unlawful sales of defeat devices; unregistered, misbranded and restricted use pesticides; and unsafe products containing toxic chemicals,” David Uhlmann from the EPA’s Office of Enforcement and Compliance Assurance said following the Justice Department’s latest action against eBay. “The complaint filed demonstrates that EPA will hold online retailers responsible for the unlawful sale of products on their websites that can harm consumers and the environment.” Ebay described the lawsuit as “entirely unprecedented”, claiming that sales of such devices were banned and that it was actively policing its site against their sale. “Maintaining a safe and trusted marketplace for our global community of sellers and buyers is a fundamental principle of our business,” the company said. “Indeed, eBay is blocking and removing more than 99.9 per cent of the listings for the products cited by the DOJ, including millions of listings each year.” Read More World’s first solar powered hybrid truck tested on public roads Why is Elon Musk obsessed with the letter X?
