Those synthetic embryos are the most fundamental things in biotechnology ever created. Those embryos had hearts and brains. So this kind of cloning technology can use for creating neurons for people whose brain is injured.

The problem with those neurons is that their memories are gone when they are destroyed. But even the existence of the "spare part" neurons makes it possible to avoid physical damage to the brain structures.

Same way as scientists can clone mice by using stem cells. They can clone humans or any other mammal. Stem cell technology can be the biotechnology of the future.

There is the possibility that before humans are born researchers take a couple of stem cells from each embryo for cryogenic storage. This thing makes it possible that each person has stem cells in a stem cell bank. Those stem cells offer the possibility to give stem cell therapy. Or that technology can use to create spare parts for people whose organs are injured.

The fact is that the DNA of the stem cells can also be stored separately. And nanotechnology allows researchers can change the DNA inside the stem cells. So theoretically if researchers have the DNA in their storage they can use even the stem cells that are taken from mice and change the DNA in the nucleus of that cell. That kind of technology allows the cloning of stem cells.

The human clones are the thing that offers one version of immortality. The person can make a copy of the body and then transfer the memories to that embryo. There is the possibility that the people of tomorrow have the microchip in their nervous system. And then microchips are copying the memories of the person to the internet. Then those memories will transmit to the younger person's brain through the cortex.

That kind of technology can open fantastic and otherwise frightening visions. That thing can give the person some kind of immortality. But it can also make it possible to create clone armies. And in some visions, the clones can also be used to replace people who are injured. Or their death wanted to be hidden. That is one vision for biotechnology, that allows researchers to create spare parts" for people.

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

The anomalies in gravity might cause dark energy.

"Physicists at UC Berkeley immobilized small clusters of cesium atoms (pink blobs) in a vertical vacuum chamber, then split each atom into a quantum state in which half of the atom was closer to a tungsten weight (shiny cylinder) than the other half (split spheres below the tungsten). (ScitechDaily, Beyond Gravity: UC Berkeley’s Quantum Leap in Dark Energy Research) By measuring the phase difference between the two halves of the atomic wave function, they were able to calculate the difference in the gravitational attraction between the two parts of the atom, which matched what is expected from Newtonian gravity. Credit: Cristian Panda/UC Berkeley" (ScitechDaily, Beyond Gravity: UC Berkeley’s Quantum Leap in Dark Energy Research) Researchers at Berkeley University created a model that can explain the missing energy of the universe. The idea is that the particles and their quantum fields are whisk-looking structures. Those structures form the superstrings that are extremely thi

Neon and time crystals can be the new tools for quantum computing.

"New research investigates the electron-on-solid-neon qubit, revealing that small bumps on solid neon surfaces create stable quantum states, enabling precise manipulation. This research, supported by multiple foundations, emphasizes the importance of optimizing qubit fabrication, moving us closer to practical quantum computing solutions." (ScitechDaily, Quantum Riddle Solved? How Solid Neon Qubits Could Change Computing Forever) Researchers created a superposition in solid neon. And those neon ions, where the system creates superposition in their surfaces. Making it possible to manipulate those atoms. The atom-based qubit has one problem. Orbiting electrons cause turbulence in their quantum fields. The thing that can solve the problem is to use the quantum fields for the superposition. If the system can position electrons at a certain point, it can make a small hill to the atom's surface. And the system can use that thing for making quantum superposition between the mos
