Google's Gemini Failure: An Analysis

A new 3D printed “metamaterial” that apparently has levels of strength for weight that appear to supersede those in nature and most of the manufacturing world has been created by a team from RMIT University‚ Australia. This new material could have significant implications for everything‚ from medical implants to aircraft to rockets.The new metamaterial – an artificially structured material exhibiting electromagnetic properties not seen in nature – is made from a common titanium alloy. But don’t let that fool you‚ there is nothing common about its ability.What makes the difference here is its structure. The material has a unique lattice design that not only makes it unique‚ but also extremely strong. According to the team’s new study‚ the material is 50 percent stronger than the next strongest alloy of a similar density‚ which is used in aerospace applications.But how did they come up with this design? As with many game-changing inventions‚ the inspiration for this new material came from observations of the natural world.  In this case‚ strong hallow-stemmed plants such as Victoria water lilies and hardy corals such as organ-pipe coral (Tubipora musica) offered instruction on how to combine lightness with durability.Yet observing a strong natural structure is one thing‚ replicating it in artificial materials is another. For decades‚ researchers have attempted to create their own hollow “cellular structures” similar to those seen in nature's examples‚ but their efforts have been frustrated by issues of manufacturing and load stress‚ which has led to failures.“Ideally‚ the stress in all complex cellular materials should be evenly spread‚” Distinguished Professor Ma Qian explained in a statement. “However‚ for most topologies‚ it is common for less than half of the material to mainly bear the compressive load‚ while the larger volume of material is structurally insignificant.”What has made the difference in this case‚ however‚ is the unprecedented innovative solutions offered by metal 3D printing.“We designed a hollow tubular lattice structure that has a thin band running inside it. These two elements together show strength and lightness never before seen together in nature‚” Qian added. “By effectively merging two complementary lattice structures to evenly distribute stress‚ we avoid the weak points where stress normally concentrates.”Strength but with little costTo create this new wonder material‚ Qian and colleagues 3D printed their design at RMIT’s Advanced Manufacturing Precinct using a technique called laser powder bed fusion. This approach melts layers of metal powder together using high-powered laser beams.The outcome was a titanium lattice cube that is 50 percent stronger than cast magnesium alloy WE54‚ the strongest alloy with a similar density. This new structure effectively halved the amount of stress concentrated on the lattice’s weak points.The structure‚ a double lattice design‚ also has the ability to deflect any cracks that may form so that they do not undermine its toughness.The structure can be scaled as needed‚ from something as small as several millimeters to structures several meters in size‚ using different types of printers. Moreover‚ the structure’s printability‚ biocompatibility‚ and corrosion and heat resistance make it a potential game-changer for applications in various areas of manufacturing.“Compared with the strongest available cast magnesium alloy currently used in commercial applications requiring high strength and light weight‚ our titanium metamaterial with a comparable density was shown to be much stronger or less susceptible to permanent shape change under compressive loading‚ not to mention more feasible to manufacture‚” lead author Jordan Noronha explained.The team now plans to refine their material and explore its application in higher-temperature environments. At the moment‚ the titanium cube can resist temperatures as high as 350°C (662°F)‚ but they think they can make it withstand temperatures as high as 600°C (1‚112°F). This would make it an excellent material for aerospace engineering and firefighter drones.However‚ the technology needed to make the new material is not yet widely available‚ so its adoption may take time. “Traditional manufacturing processes are not practical for the fabrication of these intricate metal metamaterials‚ and not everyone has a laser powder bed fusion machine in their warehouse‚” Noronha said. “However‚ as the technology develops‚ it will become more accessible and the printing process will become much faster‚ enabling a larger audience to implement our high-strength multi-topology metamaterials in their components. Importantly‚ metal 3D printing allows easy net shape fabrication for real applications.”The paper is published in the journal Advanced Materials. 

Dogs are not called our “best friends” for nothing. Apart from being our loving companions and protectors down the ages‚ many have impressive skills and talents. We’re all familiar with assistance dogs‚ like seeing eye dogs for those with visual impairments‚ but they are often specially bred and undergo years of training to learn their craft. But could your pet dog have an untapped ability? A new study reports on a years-long project that saw ordinary pets trained up to become medical detection dogs‚ able to sniff out the signature scent of Parkinson’s disease (PD).The study‚ which has been posted as a preprint and has not yet been peer-reviewed‚ took 23 very good boys and girls of various breeds‚ ages‚ and backgrounds. The culmination of a seven-year program‚ it comprised a total of 200 sessions with the dogs between 2021 and 2022.  One of the participants‚ Mia‚ doing a great job in training.Image courtesy of Lisa Holt and Sam Johnston“It takes approximately 6-8 months of training with the dogs attending 3-4 days per week‚” Lisa Holt‚ certified trainer and founder of the PADs for Parkinson’s organization‚ told IFLScience. “The dogs are trained to distinguish the difference between PD-positive sebum samples and PD-negative sebum samples. These samples have been collected from individuals with and without Parkinson’s Disease […] using T-shirts that sample donors sleep in overnight‚ or cotton swabs collected from the upper back and lower backside of the neck.”Sniffing out Parkinson’s diseaseWe know from previous research in dogs – and from observations of a woman named Joy Milne‚ who was born with an extremely heightened sense of smell – that it is possible to distinguish between volatile compounds in the sebum of individuals with and without PD‚ even before any symptoms become apparent.UK-based charity Medical Detection Dogs has been working in this area for over 15 years‚ training pooches to work with people with a multitude of conditions‚ as well as conducting research into the potential abilities of dogs to detect a range of infectious and chronic diseases.With all of this behind them‚ the team at PADs for Parkinson’s set out to trial their training regimen with a very diverse group of dogs. As Holt explained‚ there’s no one “ideal” breed for this kind of work.Topper gets stuck into the task.Image courtesy of Lisa Holt and Sam Johnston“We had an English Mastiff (brachycephalic) that performed quite well and a Basset Hound (scent hound) that was challenged. It really comes down to the individual dog’s desire to continue working to solve the odor puzzle. These are dogs that enjoy sniffing and can work independently.”The training period saw the dogs receiving a total of 320-340 exposures to the PD-positive sebum samples. Gradually‚ they worked with their trainer to cement their alert signal‚ such as a paw tap or a bark‚ which each dog was allowed to choose for themselves. Eventually‚ they started being challenged to alert to samples they’d never encountered before.Rowan having a serious schniff-schnoff.Image courtesy of Lisa Holt and Sam Johnston“For these first-time exposure‚ the 23 dogs collectively averaged 86 percent sensitivity and 89 percent specificity‚” the paper explains. Ten of the dogs were able to individually achieve sensitivities and specificities of over 90 percent. The study was also able to address an open question in the arena of olfactory detection of PD‚ namely that treatment with levodopa did not seem to impact the results. Holt envisages a future where dogs could be used to screen samples from people with early-onset PD‚ identifying those who may need further testing and potentially giving them earlier access to treatment‚ which could have a big impact on the progression of their disease. “This is how dogs could work in tandem with medicine‚ but first we would need a widely available training aid and also a method to confirm the dog’s indication‚” Holt told IFLScience.“Celebrate your dog”One of the highlights of this project came from seeing dogs that were enthusiastic and excited about the work they were doing. Holt told us one heartwarming story about a Papillon who had been distinguishing herself during the training. The training facility was on land that also played host to a county fair‚ during which time the program was paused for a week because of all the noise and distraction. Apparently‚ said Papillon didn’t quite get the memo that school was out!“During Fair week‚ her owner happened to park her vehicle in the vicinity of the County Fair (imagine there are rides‚ booths‚ goats‚ pigs‚ chickens‚ big noises‚ huge distractions everywhere and tons of people of all ages milling about) and her dog jumped out of the vehicle and ran right onto the Fairgrounds‚” Holt told IFLScience. “The owner was simply terrified […] [She] searched and searched‚ and finally… you guessed it. She found her dog standing anxiously at the entrance door to PADs waiting to come in to work.”The study provides good evidence of the potential of training domestic dogs to detect PD‚ but as Holt pointed out‚ “there are a lot of unknowns”. It’s not clear precisely which scent compounds are being detected‚ whether different dogs might detect different combinations of compounds‚ or whether PD could present with a different cocktail of compounds in different people or at different stages. Further research could help answer some of these questions‚ but it’s fair to say that the dogs have so far proven themselves up to the task.“Their sense of smell is 10‚000 to 100‚000 times more sensitive than that of a human. They can inhale and exhale at the same time. They can use their left and right nostril differently so that they smell in stereo‚” Holt told IFLScience.“Celebrate your dog. Your dog is amazing.”We couldn’t agree more.The study‚ which has been posted as a preprint and is yet to undergo peer review‚ is available at bioRxiv. 

Frank Drake‚ in the early 1960s‚ came up with an equation (called the “Drake Equation”) that calculated the possibility of extraterrestrial life. He determined that there was a possibility of 100‚000 to 1‚000‚000 extraterrestrial civilizations in our galaxy (the Milky Way) alone. With so many complex and huge solar systems across the galaxy‚ the Earth cannot be the centre of the universe. Because if it is then what is the purpose of the rest of the huge universe? Water is the main source of life on Earth. Taking a clue from this‚ European scientists‚ using ultra cold orbiting telescopes‚ have… This premium content is for PLUS+ members only.
