A lone star travels at 1% of the speed of light.

The lone star CWISE J124909+362116.0 (or “J1249+36” for short) travels in the universe with extraordinary speed. This star may have been a member of the binary star system. Astronomers suspect that the companion star in the system exploded as a supernova. This explosion drove the CWISE J124909+362116.0 to travel through the universe with extraordinary speed. But that thing is not the only model, that could explain the fast-travelling star.

Sometimes red dwarfs face the events that cause so-called super flare. Those superflares can act like rocket engines and change the red dwarf's trajectories. Also if the energy burst hits to star's atmosphere that can cause an energy impulse, that pushes the red dwarf into another trajectory.

Red dwarfs are quite light objects and impacts with things like super Jupiters can also change a lonely red dwarf's trajectory. Cosmos is a strange place and there are lots of things that can affect red dwarfs. Things like gravity and other things are the things. That can cause upheavals, and destroy entire solar systems in less than a second.

This star tells us how dangerous the universe is. Maybe in the future, this kind of thing will travel into our solar system. And that could cause horrifying events in our solar system. We all heard rogue planets, that nova or supernova explosions threw away from their solar system. But that is the first time when the red dwarf star starts to travel around the universe. This star tells lots of things about cosmic eruptions.

Things like radio, and other radiation bursts that hit stars or icy dwarf planets like Pluto can push those kinds of objects out of their trajectories. When a high-power energy burst hits the icy gas, it can vaporize the gas. That thing turns gas into the rocket engine, that pushes the dwarf planet out from its course. In the same way, high energy bursts like antimatter impact can cause asymmetry in the red dwarf's energy production.

New AI-based operating systems revolutionize drone technology.

"University of Missouri researchers are advancing drone autonomy using AI, focusing on navigation and environmental interaction without GPS reliance. Credit: SciTechDaily.com" (ScitechDaily, AI Unleashed: Revolutionizing Autonomous Drone Navigation) The GPS is an effective navigation system. But the problem is, how to operate that system when somebody jams it? The GPS is a problematic system. Its signal is quite easy to cut. And otherwise, if the enemy gets the GPS systems in their hands, they can get GPS frequencies. That helps to make the jammer algorithms against those drones. The simple GPS is a very vulnerable thing. Done swarms are effective tools when researchers want to control large areas. The drone swarm's power base is in a non-centralized calculation methodology. In that model, drones share their CPU power with other swarm members. This structure allows us to drive complicated AI-based solutions. And in drone swarms, the swarm operates as an entirety. That ca

Hydrogen is one of the most promising aircraft fuels.

Aircraft can use hydrogen in fuel cells. Fuel cells can give electricity to the electric engines that rotate propellers. Or they can give electricity to electric jet engines. In electric jet engines. Electric arcs heat air, and the expansion of air or some propellant pushes aircraft forward. Or, the aircraft can use hydrogen in its turbines or some more exotic engines like ramjets. Aircraft companies like Airbus and some other aircraft manufacturers test hydrogen as the turbine fuel. Hydrogen is one of the most interesting fuels for next-generation aircraft that travel faster than ever. Hydrogen fuel is the key element in the new scramjet and ramjet-driven aircraft. Futuristic hypersonic systems can reach speeds over Mach 20. Today the safe top speed of those aircraft that use air-breathe hypersonic aircraft is about Mach 5-6. Hydrogen is easy to get, and the way to produce hydrogen determines how ecological that fuel can be. The electrolytic systems require electricity, and electr

The neuroscientists get a new tool, the 1400 terabyte model of human brains.

"Six layers of excitatory neurons color-coded by depth. Credit: Google Research and Lichtman Lab" (SciteechDaily, Harvard and Google Neuroscience Breakthrough: Intricately Detailed 1,400 Terabyte 3D Brain Map) Harvard and Google created the first comprehensive model of human brains. The new computer model consists of 1400 terabytes of data. That thing would be the model. That consists comprehensive dataset about axons and their connections. And that model is the path to the new models or the human brain's digital twins. The digital twin of human brains can mean the AI-based digital model. That consists of data about the blood vessels and neural connections. However, the more advanced models can simulate electric and chemical interactions in the human brain. This project was impossible without AI. That can collect the dataset for that model. The human brain is one of the most complicated structures and interactions between neurotransmitters, axons, and the electrochemica
