In principle, once cameras everywhere capture enough high-resolution, overlapping views, ordinary photographs may start to feel obsolete.Instead of saving a single flat image, those recordings could be used to reconstruct a navigable 3D representation of a scene — estimating the position, shape, depth, texture, and appearance of objects from multiple camera angles.You could then return to a particular moment, move the virtual camera to almost any viewpoint, and generate a new image from that angle. Parts of the scene that were never directly visible to any camera wouldn’t be true recordings — AI would have to infer and reconstruct them from the surrounding visual information.Author: joergkahlhoefer#gaussian #splat #3DGadget and device News

The brain of a dead male fruit fly was connected to a ROBOT — giving the fly a new body and allowing it to move freely through our world again.The fly’s neural activity is translated into commands for motors that control the robot’s legs.So, in a sense, the fly is… alive again.“Black Mirror” was a documentary.@scienceGadget and device News

💡 Scientists Made a Semiconductor That Can Be Reprogrammed With LightMost computer chips are born with a fixed job. Once a semiconductor is fabricated, its electrical properties are largely locked in.Researchers at Princeton have now created an ultrathin semiconductor — only a few molecules thick — that can repeatedly change how it conducts electricity in response to different wavelengths of light. The effect is reversible, meaning the material can be programmed, erased and programmed again.The team achieved this by combining a two-dimensional semiconductor with light-sensitive molecules that physically change shape when illuminated. Those molecular changes alter the semiconductor’s electronic and optical behavior. And unlike a simple binary switch, the response can be adjusted gradually rather than just flipped between “0” and “1.”The researchers have already produced uniformScience AdvancesLarge-area, photo-programmable 2D semiconductors with chromic molecular functionalizationLarge-area films of atomically thin hybrid heterostructures enable light-programmable electronics.Gadget and device News

🧠 Singapore Just Opened a Data Center Powered by Living Human NeuronsThis sounds like science fiction, but it went live on July 16.Australian startup Cortical Labs, together with the National University of Singapore and data-center operator DayOne, has launched a biological computing facility where part of the processing is performed not by GPUs — but by living human neurons grown in a lab.Inside are 20 CL1 biological computers. Each contains at least 200,000 neurons grown on a silicon chip covered with electrodes. The neurons originate from human blood cells that are reprogrammed into stem cells and then differentiated into neurons.And yes, the computers have to be fed.Every three days, technicians supply the cells with sugar, micronutrients and pH buffers, while a life-support system regulates oxygen, nitrogen and CO₂.The strange part is that these neurons can actuallyThe Straits TimesForget silicon chip servers, Singapore’s newest data centre needs to be fedSingapore’s first biological data centre uses lab-grown brain cells for energy-efficient computing, ideal for robotics and cybersecurity with limited data needs.
