Darpa's Exacto bullets are the next step in the R&D of laser and GPS-guided projectiles.

 Darpa's Exacto bullets are the next step in the R&D of laser and GPS-guided projectiles. 


The Excato (Extreme Accuracy Tasked Ordnance) is the new tool for sniping. The bullet is guided ammunition that acts similar way to larger GPS and laser-guided artillery munitions. The guided bullet itself is not a new idea. And it has been tested a couple of times. But modern nanotechnology makes guided ammunition for rifles possible. The Exacto ammunition is highly classified. 

However, the information that is given to the public tells that Exacto is following the scope movement. And that thing tells that Excacto is laser-guided. The bullet can turn its route. It uses wings for that purpose. Or the Exacto can use the nanosize scales that are rising on the side, where the bullet needs to turn. 


The Barrett M81A1 (Wikipedia/Barrett M82) .50 Browning.  Surely, DARPA develops guided bullets also for smaller calibers than .50 Browning. And maybe, quite soon the smart bullets are coming into 5,56 mm assault rifles.

The laser that aims the bullet can be in the scope or it can be in the drone. The AI-based systems can keep the laser aimed at the target even if the target moves. There is also the possibility that the highly advanced rifle ammunition can also use GPS for aiming it into the right flight path if the aiming system is in a drone that is behind some kind of wall. The laser-guided ammunition can cooperate with small drones like "Black Hornets". The GPS controls the ammunition's flight path before it sees the target illuminated with a drone laser.  

But there is the possibility that the Exacto bullet is even more advanced. The next step for that technology is the fire-and-forget ammunition that uses similar technology to Javelin missiles, but those image recognition-based bullets require smaller microchips. And more advanced cameras. 

The DARPA develops even more advanced systems for making guided ammunition for small caliber guns. The next-generation smart bullet can use image recognition. The scope takes an image of the target and then the small-size ammunition travels into that target by compiling an image that is stored in it's memory and an image that it's nose camera uses. This kind of system requires very advanced nanotechnical components.

The new bendable sensor is like straight from the SciFi movies.

"Researchers at Osaka University have developed a groundbreaking flexible optical sensor that works even when crumpled. Using carbon nanotube photodetectors and wireless Bluetooth technology, this sensor enables non-invasive analysis and holds promise for advancements in imaging, wearable technology, and soft robotics. Credit: SciTechDaily.com" (ScitechDaily, From Sci-Fi to Reality: Scientists Develop Unbreakable, Bendable Optical Sensor) The new sensor is like the net eye of bugs. But it's more accurate than any natural net eye. The system is based on flexible polymer film and nanotubes. The nanotubes let light travel through it. And then the film at the bottom of those tubes transforms that light into the image. This ultra-accurate CCD camera can see ultimate details in advanced materials. The new system can see the smallest deviation in the materials.  And that thing makes it possible to improve safety on those layers. The ability to see ultra-small differences on surf

Quantum breakthrough: stable quantum entanglement at room temperature.

"Researchers have achieved quantum coherence at room temperature by embedding a light-absorbing chromophore within a metal-organic framework. This breakthrough, facilitating the maintenance of a quantum system’s state without external interference, marks a significant advancement for quantum computing and sensing technologies". (ScitechDaily, Quantum Computing Breakthrough: Stable Qubits at Room Temperature) Japanese researchers created stable quantum entanglement at room temperature. The system used a light-absorbing chromophore along with a metal-organic framework. This thing is a great breakthrough in quantum technology. The room-temperature quantum computers are the new things, that make the next revolution in quantum computing. This technology may come to markets sooner than we even think. The quantum computer is the tool, that requires advanced operating- and support systems.  When the support system sees that the quantum entanglement starts to reach energy stability. I

Humans should be at the center of AI development.

"Experts advocate for human-centered AI, urging the design of technology that supports and enriches human life, rather than forcing humans to adapt to it. A new book featuring fifty experts from over twelve countries and disciplines explores practical ways to implement human-centered AI, addressing risks and proposing solutions across various contexts." (ScitechDaily, 50 Global Experts Warn: We Must Stop Technology-Driven AI) The AI is the ultimate tool for handling things that behave is predictable. Things like planets' orbiting and other mechanical things that follow certain natural laws are easy things for the AI. The AI might feel human, it can have a certain accent. And that thing is not very hard to program.  It just requires the accent wordbook, and then AI can transform grammatically following text into text with a certain accent. Then the AI drives that data to the speech synthesizer. The accent mode follows the same rules as language translation programs. The ac
