The next dream of computing is photonic computers.

CC-BY-ND" (ScitechDaily, From Light Waves to Logic: The Cutting-Edge of Optical Computing)  Japanese researchers are working with fundamental optical gates that can revolutionize optical computing. The optical gates are the tools that can make it possible to create fully optical computers. In traditional versions, the optical system transmits information only between microchips.  Photonic computers use light for communication. In those systems, all wires between components are replaced using optical fiber or nanotubes. Binary photonic computers are easy to make. The shadow or cut in the light means zero. And full power light means one. In the easiest models, there are two optical wires. Wire A means 1, and wire B means 0. Those photonic beams will be sent

Researchers found a "pause" button that can stop the human embryo advance.

Researchers found a "pause" button that can stop the human embryo advance. And that thing can have many solutions. In the case of a mother's illness or injury, the medical team can save the embryo's life by stopping its advance. But that ability can make things like interstellar travel possible.  It's one theoretically, a very easy, way to transfer people to the other solar system if we don't want to get them back. The mission controllers can use the human embryos for the other solar system. Those colonists can have the robot controllers, and they can have the training material for the mission. That thing might not yet be possible. Because of our culture and moralistic-ethical thinking. Of course, technology sets limits to that kind of project.  "Research indicates that humans might harness a dormant diapause-like capability to optimize reproductive health and IVF success.

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful.  Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down.  The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

Nuclear bombs can turn asteroids.

"A plume erupts from Dimorphos as the DART mission impacts the asteroid moonlet in this artist’s concept. Such kinetic impacts are one way an asteroid might be deflected — but a new study suggests nuclear bombs could also be effective. Credit: ESA" (Astronomy.com /Nuclear bombs really could deflect asteroids, lab tests suggest) Sometimes people say that nuclear explosions will break the large asteroid into pieces. The fact is that the 500-meter asteroid causes less damage if it is in smaller pieces than in one large piece. But a large group of small asteroids can cause terrible damage in another way than some large asteroids, which can make large impact craters and megatsunamis. Asteroid debris can destroy large numbers of satellites. Large groups of small asteroids can raise the temperature in the planet's atmosphere.  In the worst scenarios, those asteroids or their impact energy turn the atmosphere glowing hot. That can be an extremely dangerous situation. The asteroid

New prostheses and robot vehicles are impressive.

"Experimental tests on robotic prosthesis: clothespin. Credit: © 2024 Scuola Superiore Sant’Anna" (ScitechDaily, “It Feels Like I’m Moving My Own Hand” – Science Fiction Comes to Life With Magnetic Prosthetic Hands) The new advances in AI and computing make it possible to create new advanced robots. Those robots can transmit their senses to their users.  New advances in robotics and AI are tools that are making new solutions that seem like SciFi possible.  By using those new tools researchers can make prostheses with touch and self or half -self-driving cars possible. The prosthesis with a sense of touch is a big thing. We all know that. But it can be even bigger than we ever imagined. That system allows to creation of new tools like external bodies. The external body, or exobody means remotely controlled robots that can transmit a sense of touch and all other senses to the user.  This thing makes those robots very good tools for things like high-risk missions in civil and mi

Researchers found the origin of the black hole X-ray emission.

Credit: Jani Närhi (ScitechDaily, Solving the Puzzle of X-Ray Radiation From Black Holes) University of Helsinki researchers made a model that explains the black hole's X-ray emission. The thing is that the researchers looked too much about the gravity of the black hole. The black hole itself pulls a magnetic field inside it at the point of the event horizon. But the plasma that surrounds the black hole can form a magnetic field.  This magnetic field makes the relativistic jet possible. The magnetic field that forms when material orbits the event horizon is the thing that forms the conditions where those X-rays can come. When particles in the magnetic field jump out from the black hole's orbiter at the point of relativistic jet impact with plasma whirling around it.  That forms a very high temperature. There are also differences in the speed of gas in the material disk. And that forms th

Uncertainty principle.

"Today, the Universe has evolved into the complex, life-friendly place we know it to be because we were able to form neutral atoms early on in the Universe. Yet without just the right quantum properties, the formation of stable, neutral atoms would have been delayed significantly, or might not have even occurred at all." (BigThink, What is the origin of quantum uncertainty?) "The uncertainty principle, also known as Heisenberg's indeterminacy principle, is a fundamental concept in quantum mechanics. It states that there is a limit to the precision with which certain pairs of physical properties, such as position and momentum, can be simultaneously known. In other words, the more accurately one property is measured, the less accurately the other property can be known." (Wikipedia, Uncertainty principle) The uncertainty principle means: that if we focus on one quantity. We cannot keep focus with the same accuracy on other quantities. In simpler saying, if we focus
