E-commerce giant Amazon has said it uses artificial intelligence systems to prevent fake reviews on the platform that can intentionally mislead customers. While the company already uses machine learning models to detect risks such as links to other accounts, sign-in activity, review history, and other indications of unusual behavior that point to fake reviews, the tech giant said on Tuesday that is further investing in sophisticated fraud-detection tools. Using several such methods, the company said it “proactively blocked over 200 million suspected fake reviews” from its stores in 2022. “We will continue to build sophisticated tools that protect customers, our selling partners, and our store from bad actors that attempt to profit by proliferating fake reviews globally,” Amazon said. In the new statement, the e-commerce giant warned of the emergence of an illicit industry of “fake review brokers,” who approach consumers via social media channels, and messaging services, soliciting them to write fake reviews in exchange for money or other incentives. These brokers, according to Amazon, portray themselves as legitimate businesses with networks of hundreds of employees stationed worldwide. So far, it has taken legal action against over 90 such bad actors around the world who facilitated fake reviews and sued more than 10,000 Facebook group administrators who attempted to put fake reviews. It also reported over 23,000 abusive social media groups, with over 46 million members and followers, that facilitated fake reviews in 2022, the company added. These high-volume fake review brokers a “global problem” impacting multiple industries, according to Amazon, which called on the private sector, consumer groups, and governments to work together to stop fake review brokers. “Through cross-industry sharing – including information on bad actors’ tactics and techniques, who they are targeting, the services they provide, and how they operate – we can more effectively shut down these schemes, thereby protecting more consumers across different industries,” the company said. In countries that already have laws against soliciting fake reviews, it said regulators could do more to use their authority to take action against fake review brokers. “We also support greater funding for law enforcement to build further technical expertise to investigate and take down these brokers,” the multibillion-dollar conglomerate said. “Amazon will continue to protect our stores from fake reviews by investing in proactive tools to detect and stop fake reviews from impacting a customer’s buying decision,” it added.

Happiness is one of life’s most elusive gifts – it is an emotion that can’t be pinned down. And yet, an animation showing a protein molecule “walking along”, carrying a large sphere, is widely credited with being a visual representation of joy itself. The gif has trended online for almost a decade but continues to breed delight in those who see it. Many people believe that it is – to use the technical terms – a myosin transporting endorphins in the brain. In other words, it is a scientific portrayal of the actual processes that give us that warm and fuzzy feeling.

In fact, the real brain behind the original clip, medical artist John Liebler, set out the truth back in 2014. @mommyca713 AMAZING! #cells #innerlife #happiness #lookslike #facts #fact #fyi #fyp #brain #research #facts #animation #myosin #interesting #education #viral #fypシ #humanbrain #mentalhealth #science #stem He explained that he, his team at medical technology company XVIVO, and two Harvard University researchers created the 3D computer animation in 2006 for a biology classroom video called ‘The Inner Life of the Cell’, as Science Alert reports. The educational clip wasn't intended to depict a brain process at all but to take the viewer "on a journey through the microscopic world of a cell, illustrating mechanisms that allow a white blood cell to sense its surroundings and respond to an external stimulus,” according to Liebler himself. So this is all about a protein in a white blood cell, not a protein in a neuron. The Inner Life of the Cell Animation youtu.be At any rate, happiness doesn’t just come about through a single process. So even if the clip did show endorphins being delivered to our brains, this wouldn’t offer a full picture. Dopamine, other neurotransmitters (for example, serotonin), biological health and genetics all play a part in cementing our feelings of contentment. We don’t just rely on jolly little myosin proteins lugging around bundles of cheer. Still, the internet is now awash with jovial variations on the clip and it can’t be denied that the scene-stealing strutting protein is pretty damn cute. So if that’s enough to bring a smile to your face, maybe it is a representation of happiness after all. Have your say in our news democracy.
