The UK’s first-ever “ghost driver” has taken to the roads of Nottingham in a new experiment. A driverless car was been fitted visual displays to communicate with people crossing roads to determine how people respond naturally to self-driving vehicles. The screen shows different images to pedestrians - including a happy face, a giving way face, and a raised eyebrow. A University of Nottingham study found that, in the absence of someone in the driving seat, pedestrians trust certain visual prompts more than others when deciding whether to cross in front of an autonomous car.

A major security vulnerability had the potential to hit “billions” of computers, according to the Google researchers who discovered it. The security flaw, dubbed “Downfall”, attacked Intel processors in a way that would allow hackers to steal passwords, encryption keys and private data from users. That’s according to Daniel Moghimi, the senior research scientist at Google who found the problem and disclosed it this week. He alerted Intel about the issue with its chips, and the company has since sent out an update to fix it. But the issue could have affected “billions of personal and cloud computers”, Google said. “Had these vulnerabilities not been discovered by Google researchers, and instead by adversaries, they would have enabled attackers to compromise Internet users,” the researchers wrote in a blog post. The attack worked by breaking through the boundary that is intended to keep software safe from attacks on the hardware. In doing so, attackers would have been able to find data that belongs to other users on the system, the attackers said. It did so by exploiting technologies that are intended to speed up various processes on the chip. Attackers were able to exploit those tools to steal sensitive information that should have stayed available only to its owner, when they were signed in. The nature of the attack means that hackers would need to be on the same physical processor as the person they are attacking. But that would be possible using malware, or the shared computing model that powers cloud computing, for instance. Intel said that the problem does not affect recent versions of its chips, and that the fix does not cause major problems. But it did suggest that users could disable the fix, if they thought the risk was not worth the slight drawbacks in performance. The company also told Bleeping Computer that “trying to exploit this outside of a controlled lab environment would be a complex undertaking”.

Scientists think they could have found the cause of a series of “slow-motion” earthquakes that have shaken New Zealand in recent years – a hidden ocean which sits two miles beneath the sea floor. The water was revealed as part of a giant volcanic area formed about 125 million years ago, when an eruption forced a plume of lava bigger than the US to the surface of the Earth. Researchers found the region by towing 3D seismic sensors behind a boat to build up an image of the ancient volcanic area. There, they found thick, layered sediments around long-buried volcanoes which contained much more water than expected. Andrew Gase, from the University of Texas Institute for Geophysics, who carried out the research, said: “Normal ocean crust, once it gets to be about seven or 10 million years old should contain much less water.” The ocean crust scanned by researchers was 10 times as old as this – but water made up nearly half its volume. The tectonic fault line which runs through New Zealand is known for producing slow-motion earthquakes, also known as slow slip events. During one of these, the energy from an earthquake gets released over days or months, often causing little or no harm to people. Scientists don’t know why they happen more at some faults than at others, but they are thought to be linked to buried water. Finding this new area of water at the fault line which creates so many slip events could provide an explanation. Gase said: “We can't yet see deep enough to know exactly the effect on the fault, but we can see that the amount of water that's going down here is actually much higher than normal.” If researchers can work out how the water reserves affect slip events – possibly by dampening them – they could, in turn, understand normal earthquakes better. Scientists also think underground water pressure could play a key part in creating conditions that release tectonic stress via slow slip earthquakes. As a result, Gase said scientists should drill even deeper to find out where the water ends up. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

It’s been 10 years since Jeffrey Bush disappeared in his own home, and no trace of him has ever been found. The 37-year-old was asleep in bed at his home in Seffner, Florida, when the ground caved in around him, swallowing him into a massive sinkhole. On the night of February 28, 2013, his brother Jeremy heard a loud crash and ran into Jeffrey’s room only to find a vast crater in place of his sibling’s bed. Jeremy jumped into the hole in a desperate bid to rescue his brother but was swiftly pulled to safety as the ground around him continued to cave in. Sign up for our free Indy100 weekly newsletter "The floor was still giving in and the dirt was still going down, but I didn't care. I wanted to save my brother," he told The Guardian at the time. "But I just couldn't do nothing. "I could swear I heard him hollering my name to help him." Within minutes, local law enforcement had arrived and engineers lowered a microphone into the pit to try to pick up signs of Jeffrey. However, a second collapse sucked the equipment down into the sinkhole and the property was deemed too dangerous for rescue or recovery. Video released of Seffner sinkhole that claimed life of Jeff Bush youtu.be The house was subsequently fenced off and eventually demolished, with the gaping 20ft-wide cavity filled in with gravel. But then, more than two years later, on August 19, 2015, the hole reopened. Specialists at the time pointed out that it was very rare to see such a phenomenon reemerge in the exact same spot. Florida is particularly susceptible to sinkholes as it is home to a high number of underground caverns which are made up of limestone, a rock which easily dissolves in water. In fact, they’re so common, that state law requires home insurers to provide coverage against the danger. And, indeed, someone had visited the Stevens’ home just weeks before the tragedy to check for sinkholes and other risks on the property, apparently for insurance purposes. "[The inspector] said there was nothing wrong with the house. Nothing,” Jeremy told The Guardian. “And a couple of months later, my brother dies. In a sinkhole.” So what happened to Jeffrey’s body? Well, Philip van Beynen, a University of South Florida environmental scientist, concluded that it had most likely dropped into a 60ft-tall water-filled void between the sinkhole and the lower bedrock. The body would have sunk much deeper than the gravel pit seen from the street, van Beynen told USA Today. He stressed that any attempt to retrieve it would have been unwise, if not impossible, as the ground around the hole could have collapsed as well. "It would be extraordinarily difficult and incredibly expensive," he noted. Still, that’s little comfort to the Stevens’ who never got to bury their loved-one or, even, to properly say goodbye.
