How remote-controlled cyborg BEETLES with microchip backpacks could help save lives in horror disasters
Published: Invalid Date,
REMOTE-controlled cyborg beetles wearing microchip backpacks could be used to save lives in horror disasters.
Two boffins at the University of Queensland (UQ) in Brisbane, Australia, are building the smallest search and rescue team.

They say the plan could cut the time it takes to find someone trapped under rubble from days to hours.
The darkling beetles (Zophobas morio) can be controlled with video game controllers if they are fitted with the chips, Dr Thang Vo-Doan and Research Assistant Lachlan Fitzgerald have found.
The chips shock the beetles into moving in a certain direction by stimulating the insect's antenna or hardened forewings known as elytrons.
So far, they've been able to move the cyborg bugs side-to-side and up vertical walls.
Dr Vo-Doan said: "Beetles possess many natural gifts that make them the masters of climbing and manoeuvring in small, complex spaces such as dense rubble, that are difficult for robots to navigate.
"Our work harnesses these gifts and adds programmable controls that allow for precise directional guidance, without affecting the lifespan of the beetle."
The science is being done by a team of researchers at the Biorobotics lab in UQ's School of Mechanical and Mining Engineering, who hope to test the technology in a live situation within five years.
Fitzgerald said: "While robots at this scale have made strides in locomotion, the transition from horizontal surfaces to walls remains a formidable challenge for them.
"This difficulty arises from the need for active foot pads, soft environmental interactions, and sophisticated sensing capabilities - all things that our cyborg insects possess naturally that allows them to access any area that is required in a disaster environment."
Dr Vo-Doan said while a tethered power supply had been used for the climbing test, the beetles were able to climb with a battery equivalent to its own body weight.

The team is next working on cameras and a compact and efficient power system to enhance the beetle's mobility and versatility.
Dr Vo-Doan said: "If people have been trapped under an extensive amount of rubble, you want to be able to find them as quickly as possible and start planning how to get them out.
"We hope to produce a tool that can easily move through chaotic environments to pinpoint a person's exact location, provide clues to any injuries, and give rescuers a picture of what needs to be done to free them".
The cyborgs also use a minimal amount of power on each run compared with miniaturised robots that are currently being modelled.

It's not the first time that beetles have been fitted with backpacks and used for search and rescue.
Scientists in China built beetles that wore backpacks and could be controlled remotely - but which also could test for carbon dioxide poisoning.
Boffins have also created a similar set of cyborg cockroaches.
Stuck on the back of real-life Madagascan hissing cockroaches, the chip sits on a panel that uses an infrared camera and a series of sensors to collect and send data to first responders.
The original idea for the hero insects comes from Professor Hirotaka Sato.
He witnessed the devastation caused by the 2011 Japanese earthquake first-hand and quickly realised there needed to be a faster and more effective way of finding survivors and victims.
He said: 'Our motivation is purely to use this technology for search and rescue. To save people from disaster.'

Face age and ID checks? Using the internet in Australia is about to fundamentally change
As the old adage goes, 'On the internet, nobody knows you're a dog'. But in Australia it might soon be the case that everything from search engines and social media sites, to app stores and AI chatbots will have to know your age. The Albanese government trumpeted the passage of its legislation banning under 16s from social media – which will come into effect in December – but new industry codes developed by the tech sector and eSafety commissioner Julie Inman Grant under the Online Safety Act will probably have much larger ramifications for how Australians access the internet. Measures to be deployed by online services could include looking at your account history, or using facial age assurance and bank card checks. Identity checks using IDs such as drivers licences to keep children under 16 off social media will also apply to logged-in accounts for search engines from December, under an industry code that came into force at the end of June. The code will require search engines to have age assurance measures for all accounts, and where an account holder is determined to be aged under 18, the search engine would be required to switch on safe search features to filter out content such as pornography from search results. Six more draft codes being considered by the eSafety commissioner would bring similar age assurance measures to a wide range of services Australians use every day, including app stores, AI chatbots and messaging apps. Sign up for Guardian Australia's breaking news email Any service that hosts or facilitates access to content such as pornography, self-harm material, simulated gaming, or very violent material unsuitable for children will need to ensure children are not able to access that content. In her National Press Club speech last month, Inman Grant flagged that the codes were needed to keep children safe at every level of the online world. 'It's critical to ensure the layered safety approach which also places responsibility and accountability at critical chokepoints in the tech stack, including the app stores and at the device level, the physical gateways to the internet where kids sign-up and first declare their ages,' she said. The eSafety commissioner announced the intention of the codes during the development process and when they were submitted, but recent media reporting has drawn renewed attention to these aspects of the codes. Some people will welcome the changes. News this week that Elon Musk's AI Grok now includes a pornographic chat while still being labelled suitable for ages 12+ on the Apple app store prompted child safety groups to call for Apple to review the app's rating and implement child protection measures in the app store. Apple and Google are already developing age checks at the device level that can also be used by apps to check the age of their users. Founder of tech analysis company PivotNine, Justin Warren, says the codes would 'implement sweeping changes to the regulation of communication between people in Australia'. 'It looks like a massive over-reaction after years of policy inaction to curtail the power of a handful of large foreign technology companies,' he says. 'That it hands even more power and control over Australians' online lives to those same foreign tech companies is darkly hilarious.' One of the industry bodies that worked with the eSafety commissioner to develop the codes, Digi, rejected the notion they would reduce anonymity online, and said the codes targeted specific platforms hosting or providing access to specific kinds of content. 'The codes introduce targeted and proportionate safeguards concerning access to pornography and material rated as unsuitable for minors under 18, such as very violent materials or those advocating or [giving instructions for] suicide, eating disorders or self-harm,' Digi's director of digital policy Dr Jenny Duxbury says. Sign up to Breaking News Australia Get the most important news as it breaks after newsletter promotion 'These codes introduce safeguards for specific use cases, not a blanket requirement for identity verification across the internet.' Duxbury says companies may use inference measures – such as account history or device usage patterns – to estimate a user's age, which would mean most users may not have to go through an assurance process. 'Some services may choose to adopt inference methods because they can be effective and less intrusive.' However, those that do may be caught by surprise when it comes into effect, says Electronic Frontiers Australia chair John Pane. 'While most Australians seem to be aware about the discussion about social media, the average punter is blissfully unaware about what's happening with search engines, and particularly if they go to seek access to adult content or other content that is captured by one of the safety codes, and then having to authenticate that they're over the age of 18 in order to access that content, the people will not be happy, rightly so.' Companies that don't comply with the codes will face a fine similar to that of the social media ban – up to $49.5m for a breach. Other measures such as eSafety requesting sites be delisted from search results are also an option for non-compliance. Pane says it would be better if the federal government made changes to the privacy act and introduced AI regulation that would require businesses to do risk assessment and ban certain AI activities deemed an unacceptable risk. He says a duty of care for the platforms for all users accessing digital services should be legislated. 'We believe this approach, through the legislature, is far more preferable than using regulatory fiat through a regulatory agency,' he said. Warren is sceptical the age assurance technology will work, highlighting that the search engine code was brought in before the outcome of the age assurance technology trial, due to government this month. 'Eventually, the theory will come into contact with practise.' After recent media reporting about the codes, the eSafety commissioner's office this week defended including age assurance requirements for searches. 'Search engines are one of the main gateways available to children for much of the harmful material they may encounter, so the code for this sector is an opportunity to provide very important safeguards,' the office said.

Dr Karl Kruszelnicki: ‘I took my hands off the artery – blood squirted up and hit the ceiling'
You're about to give a series of talks on the history and explosion of AI. Who is your favourite fictional robot? I guess the robots in general from Isaac Asimov. He came up with the three laws of robotics, which are basically that a robot has to obey a human, it can't harm itself, and it can't harm another human. My favourite robot is one [from Asimov's The Bicentennial Man] that served a family for many, many years – in fact, generations – and eventually became human. If you could change the size of any animal to keep as a pet, what would it be? To put a downer on it, we're full of children and nieces and nephews and grandkids, so we don't want pets. But I do see the value of a pet. It's tricky. In Australia, cats kill a million birds a day. Dogs are nice, but when I was a doctor in a kids hospital, once I realised that dogs would rip the faces off 15,000 kids every year, I kind of fell out of love with big dogs. So I reckon dogs. Shrink them down. A border collie, they're the smartest dog. What do you do when you can't get to sleep? Get up, work for a bit, then go to sleep again when I feel tired. If I'm awake enough to do stuff, I'll do stuff. I love reading. My job is to read the scientific literature and turn it into stuff that people can understand. I've been reading articles about how we've got this history of human diseases over the last 37,000 years, and how many diseases have actually invaded our DNA, or how some frogs will fake death to avoid sex, or how the French in the early 1800s had the great moustache wars, or the TV viewing habits of dogs. Or the word 'cool' – where did it come from, and what's the concept behind it? Or the amount of energy used from AI to make a single picture, as opposed to a human, or why you get traffic jams in the middle of nowhere, or how you use earwax as a diagnostic tool. Or, if you get a shark and turn it upside down, about half the species will just stop moving. And that's just today's reading! What is your most controversial scientific opinion? The two big ones would have to be climate change and vaccination, and the controversy behind them is just pointless. You know how insurance companies are making it more expensive in certain areas to insure because of extreme events caused by climate change? OK, so when do you think the insurance companies started doing that? 1973! [It wasn't until 1980 that] fossil fuel companies, with a budget of up to a billion dollars a year, started denying climate change. And that's why I've got this so-called controversy. What is the oldest thing you own, and why do you still have it? I've got a bit of rock from a mining site that was dated to 1bn years old. I've also a meteor that my father saw land in our front garden when I was a kid, and the next morning, we went out to dig it up. I reckon that'd be a couple of billion years old. It's about the size of a golf ball. It's now on the display shelf halfway up the stairs. Would you rather die at the bottom of the ocean or out in space? Probably space. But it depends how it happens. One thing I learned as a medical doctor is that everybody has to die, but you should have a good death. We had one patient who had cancer of the everything, and she was really going to die. We made it our personal project that she'd have a good death. We ended up cranking her morphine from 5mg a day to 30,000 – that's a big jump, isn't it? Her legs were the diameter of your wrist by the time she died, but she didn't die in pain. So that convinced me, I want to have a good death. Sign up for the fun stuff with our rundown of must-reads, pop culture and tips for the weekend, every Saturday morning If you're in, say, a submarine, and then the pressure overcomes the structural integrity of the vessel's walls, then you're dead in about a tenth of a second, a hundredth of a second – whereas in space, it might take a while to die, maybe a few minutes. So whichever one was quicker. But the view's nicer in space. What is the strangest job you've ever had? I started working at the steelworks at Wollongong when I was about 19. I ran a little aluminium boat measuring the acidity or alkalinity of the water in this little creek inside the steelworks. Depending on whether it was green or orange, it varied between incredibly acid and incredibly alkaline. And either way, it would eat through the skin of the aluminium boat in about six months. Sign up to Saved for Later Catch up on the fun stuff with Guardian Australia's culture and lifestyle rundown of pop culture, trends and tips after newsletter promotion Back then, I was taught 'the solution to pollution is dilution' – chuck it in the ocean, nobody will ever notice. It was pretty bad back then, and hasn't got much better since. What is the most chaotic thing that's ever happened to you at work? I was in an operating theatre. I was assisting. I was really tired. I'd done an incredibly long number of shifts, dozens of hours in a row, and I was instructed to lean on an artery. I started to fall asleep standing up, and the surgeon said, 'Hey, wake up, Karl!' I stood up with a jerk and took my hands off the artery – blood squirted up and hit the ceiling. If you had to add any colour to the rainbow, what would it be? Around the world, the number of colours that people see in the rainbow varies between four and 16. The reason we have seven colours in our rainbow is because of Isaac Newton. Besides being one of the true geniuses, he also spent more time on Bible studies than he did on science. And all the way through the Bible the number seven comes up all the time. Based on him following the work of some Muslim scientists, he did an experiment with a prism – like the Dark Side of Moon album cover, which, by the way, is wrong from a physics point of view. Anyway, he sees these colours. Six colours. But he loves the Bible, and the Bible has seven everywhere, so he sticks in stupid fucking indigo. What sort of colour is indigo? It's just blue! So I refuse to add another colour to the rainbow. I'll go the other way; I'll remove indigo and get back to six colours. Lastly, please settle this debate for us once and for all, scientifically: should tomato sauce be kept in the fridge or the cupboard? The problem that you want to avoid is bacterial or fungal infection of the tomato sauce. Now, the tomato sauce, I imagine, would be mostly water, and then it's got some varying mix of fat, protein and carbohydrate, which would be foods for bacteria and yeast. If you stick it in the fridge, you really lengthen the time before the bacterial or fungal overgrowth gets dangerous. But you end up in the terrible situation that you shake and shake and shake the bottle and first none will come, and then the lot will because it's been frozen to a solid lump. So the argument for not putting in the fridge is that it'll pour more easily. In that case, you need to actually observe, and if you start to see the first hint of bacterial or fungal contamination, feed it to the compost and get another bottle. It sounds like you're pro-cupboard, pro-observation. Well, life's complicated. Nothing's simple. I'm sorry. I'm probably overcomplicating life. Dr Karl will appear at three events at Tasmania's Beaker Street festival, 12-24 August
