Researchers created fully synthetic embryos.

Researchers at Weitzmann Scientific Institute created human embryos from stem cells without sperm and eggs. That kind of thing is a breakthrough in genetic research. The ability to create a human embryo from stem cells is one of the most interesting things in the world of cloning and genetic research. The "virgin born" embryo is the thing that causes very interesting thoughts about abilities to use that technology in positive and negative things.

The Weizmann-institute embryos are similar to all other embryos. And that means somebody can "steal" one of those embryos and then use that embryo for artificial insemination. Artificial embryos are meant for cancer and other types of research. But maybe some people think that those embryos offer the possibility to make artificial people for some purposes that we cannot even imagine.

Normally, when we think about genetic engineering and super soldiers that serve in the clone army we think of the system, where the blastula-stage embryo will split in two parts. Then the other one will be put in the freezer into liquid nitrogen. The other part of that sliptted embryo will grow as normal people. Then if that person does the duties well, the system can turn also another part of the embryo into life. There could be different groups of those embryos, and the system selects the best of the best.

That kind of thing is interesting but at the same time frightening vision about things like the military. The ability to create a fully synthetic embryo means the ability to create a fully synthetic person. Those kinds of people have no connections with their parents. In some visions, the first people who will colonize the solar system and travel out from our planetary systems are that kind of clone.

Technology that the Weizmann Institute used in that operation can also be used to make immortal crews for interstellar flights. The immortal crew means that all crew members will cloned, and then the system transfers their memories to those clones.

Chinese innovations and space lasers are interesting combinations.

(Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th

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

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
