Astronomers found the rare second-generation star in the Large Magellanic Cloud.


"The first generation of stars fundamentally changed the universe by fusing simple elements like hydrogen and helium into more complex ones within their cores, scattering these elements across space upon their death—elements that are now part of the Earth and living beings. Recently, scientists discovered a second-generation star from another galaxy, offering unique insights into the early elemental formation processes in galaxies beyond the Milky Way." (Wikipedia, Cosmic Oddity: Rare Second-Gen Star Found Beyond the Milky Way)

The old star is the thing that opens our knowledge of stellar formation. This scarce star formed from the first generation star's remnants. The particles that formed this second-generation star are from the first stars in the universe. That thing makes this distant star very interesting. 

And it can broaden our knowledge about star formation. The old star in the Large Magellanic Cloud can also mean that there are other old stars in that galaxy. The old stars are also good points to start the search for alien civilizations. If we want to find a technically advanced civilization, we must find a star that is mature enough. 

The star must have planets that have enough time so that civilization can create technology. That thing makes old stars interesting. And the thing is that those stars tell stories from the young universe. When we think that the Sun is a third-generation star. 

We must ask when heavier elements formed. Were some of the first generation of stars formed those heavy elements, that metal-rich rocky planets require? Or did heavy elements form, not until the second or third-generation stars formed? 

Heavy elements are necessary when the metal-rich large rocky planets form. The thing is that advanced civilization requires a solid-shell planet for life.  The gas giants cannot maintain advanced lifeforms. Or those lifeforms must move to that planet from somewhere else. Old stars give a tip, on where we should aim our radiotelescopes if we want to find a mature civilization that could create some technical advances.

Researchers created fully functioning mini brains using bioprinters.

  "Currently, the global annual cost of treating brain diseases amounts to €3 trillion. (Image: Mostphotos)" (University of Helsinki, Development of human-derived mini-brain close to completion - A new technical solution promotes the treatment of brain diseases) When we think that AI cannot reach the same intelligence level as humans, we talk about binary-computer system-based AI. That AI is a very passive thing. But biological microchips where living neurons communicate with microprocessors are different things. Those systems are in mini-brains. Or cloned neurons that developed for medical testing. Those mini brains involve living neurons that interact similarly, to neurons in the human body.  "Scientists at the University of Wisconsin–Madison (UWM) say they have created the first 3D-printed brain organoids that function like natural brain tissue." (FreeThink, Scientists create the first “functional” 3D-printed mini brains) “The neurons communicate, send signals, i

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.

Wormholes and fundamental avionics.

Image
Thoughts about wormholes and hypothetical engines.  Acoustic and electromagnetic systems can create acoustic or electromagnetic channels through air or water. The system can create an acoustic beam or laser beam, that pushes air molecules out of the aircraft's way. That makes the air thinner. And that allows the aircraft to move faster than usual.  An interesting way to raise objects silently up from the ground is to use the tornado that formed above the craft. There is a hatch under the craft and then the system creates an artificial tornado above the craft. Then the craft closes the hatch, and the tornado above the craft pulls it up. The system requires a hatch that can feed rising tornado using air.  The hatch allows it to rise that tornado high enough, that it can pull objects up. The hatch can also used for the acoustic tractor beam. The acoustic tractor beam is the tornado that pulls objects up from the ground. The horizontal tornado makes the craft move faster or it removes
