In the mid-19th century, Bernhard Riemann conceived of a new way to think about mathematical spaces, providing the foundation for modern geometry and physics. Standing in the middle of a field, we can easily forget that we live on a round planet. We're so small in comparison to the Earth that from our point of view, it looks flat. The world is full of such shapes--ones that look flat to an ant living on them, even though they might have a more complicated global structure. Mathematicians call these shapes manifolds.

Brandon Dawson's prize-winning pumpkin weighs as much as a bison. Breakthroughs, discoveries, and DIY tips sent every weekday. After narrowly missing the title last year, electrical vehicle engineer Brandon Dawson won the top prize at the Safeway World Championship Pumpkin Weigh-Off in Half Moon Bay, California. His humongous gourd weighed a staggering 2,346 pounds. The annual pumpkin weighing contest has been likened to the Super Bowl of pumpkin growing.

Amidst the chaos and upheaval at the Social Security Administration (SSA) caused by Elon Musk's so-called Department of Government Efficiency (DOGE), employees have now been asked to integrate the use of a generative AI chatbot into their daily work. But before any of them can use it, they all need to watch a four-minute training video featuring an animated, four-fingered woman crudely drawn in a style that would not look out of place on websites created in the early part of this century. Aside from the Web 1.0-era graphics employed, the video also fails at its primary purpose of informing SSA staff about one of the most important aspects of using the chatbot: Do not use any personally identifiable information (PII) when using the assistant. There is nothing wrong with your speakers; WIRED has disabled the sound. "Our apologies for the oversight in our training video," the SSA wrote in a fact sheet about the chatbot that was shared in an email to employees last week.

Despite their inability to take to the skies, birds like ostriches, emus, and chickens use their wings--they're actually vital to their everyday movements. And unlike existing biomimetic robots that take their cues from high-flying birds, researchers at China's Shandong University recently built a new, strutting machine inspired by terrestrial avians. "[H]umans swing their arms to counteract the angular momentum generated by their legs during high-speed movements, such as sprinting," engineer Xianwu Zeng explained to TechXplore. "Similarly, ostriches and roadrunners use their wings for flight but flap them during rapid running, jumping, or sharp turns, where the wings serve as auxiliary mechanisms." With these biological influences in mind, Zeng and colleagues have designed KOU-III.

Asset Entities is a publicly listed set of social media accounts and Discord servers that churn out get-rich-quick tips for Gen Z. It reported a net loss of $413,000 last year. But give Texas-based vice president Kyle Fairbanks just 21 49 seconds and he'll tell you how to (maybe) make $20,000 a month arbitraging AirBnbs up and down the East Coast. He has an extensive corpus. For a few wondrous hours on Monday it was the Nasdaq's best-performing stock.

A team of scientists has used GPU-accelerated deep learning to show how color can be brought to night-vision systems. In a paper published this week in the journal PLOS One, a team of researchers at the University of California, Irvine led by Professor Pierre Baldi and Dr. Andrew Browne, describes how they reconstructed color images of photos of faces using an infrared camera. The study is a step toward predicting and reconstructing what humans would see using cameras that collect light using imperceptible near-infrared illumination. The study's authors explain that humans see light in the so-called "visible spectrum," or light with wavelengths of between 400 and 700 nanometers. Typical night vision systems rely on cameras that collect infrared light outside this spectrum that we can't see.

If you've never picked a raspberry, well, first of all that's too bad, because a fresh raspberry is a beautiful thing. But second, and more immediately relevant in this case, you would not know that there is a technique to it that, surprisingly, robots aren't super good at because they tend to be… crushy. But this robo-berry designed by Swiss researchers could usher in a new era of gentle, automated robo-pickers. The secret to picking a raspberry is to grip it just enough to get purchase and then pull it downwards off the little stem, apparently called the "receptacle," which seems backwards. Seems simple -- and it is, but only our hands are among the most sensitive and finely controlled constructions in the universe, the culmination of a hundred million years of evolution, outdone only by (I suspect) raccoons.

The battle around the walking simulator term, like many definitional fights, was a political one. Calling something a walking simulator carried a declarative weight to it, as if the act of walking was so surface level and pointless that to call it a "game" had no value. At the time, Paste Magazine's Austin Walker connected the motivating conversations in game design and criticism together, noting that discussions of form and content always resolved into bigger historical debates about what does and does not belong within any given culture. The discussion reached an apex with a 2016 Kill Screen piece that interviewed critics and developers of these games about how they understood walking simulators and the discourse around them. For some, "walking simulator" was a useful descriptor that allowed them to connect with a player base.

Jana Denzel explores artificial intelligence and the role it will play in the world of dentistry. Movies such as The Terminator and I, Robot hauntingly illustrate futuristic worlds shaped by technological innovations that arose from artificial intelligence (AI). However, that scientific-fiction AI is what's known as'artificial general intelligence'. In other words, computer intelligence almost identical from human intelligence – and, to date, it remains very much a fantasy. 'Narrow AI' is the label that scientists give to the AI that's incorporated into our world today.

AI is transforming various facets of technology, with none outside its purview. Testing is one such area in which AI is set to do wonders and organisations must move in tandem with the changes that AI is slowly bringing to stay competitive. Application crash or malfunctioning can not only destroy the application's reputation, but it can irreparably damage the brand. According to the Cambridge University study, Testing comprises 25-40% of the entire developmental expenses, and the total spending on testing exceeded USD 300 bn in 2017. The numbers unequivocally undermine the importance of testing.
