Single-celled slime mold can remember the place of its food


The mold that can smell the location of its food can be used as a biocompass. Or the same molds can be used to make the synthetic smell for robots. 

The single-celled mold, what can remember the location of its food can give new visions for the evolution scientists. But the fact is that this kind of mold, which can react to the chemicals, voice, or magnetic fields can be used to control drones. If that sense of the mold depends on the magnetic field, it can make drones like letter dove. That kind of mold will make it return to base, even if the control signal is gone. 

If the mold reacts to voice or certain chemicals, that allows using sound or some chemical marks for making drone travel with a certain track. The mold would put in the chamber, where the sensor is searching its movement. And then the drone would travel to the direction, where that mold is showing. If the mold can sense chemical marks from the air, it can be used to track the chemicals. 

And if the location happens by sound the mold can be used as a biosensor, which is telling where the source of the sound is. The idea is that when the mold is locating its nutrient, it starts to travel to it. So if it has the RFID or some other marks, the sensor in the drone can locate the movement of the direction of the fungus. And that thing gives the smell to the robots. 

But it can also give new visions for people, who are creating the biorobots. If the mold has grown over the layer, where is a certain chemical combination, that mold would keep it as its food? So the mold can be used as the biological tracking tool, which is searching for some chemicals. If the mold is grown in culture, where are things like narcotics or some other mold, that mold can deliver to the house, and it would search those things even in the tiniest bricks. 

Those slime molds can be implanted with tracking tools like RFID-sensors, which are used to track the movement of that fungus. For success, that tool requires that the mold can "smell" its nutrient through the air, but even it requires all-time contact between nutrient and cell, it can use to track the vehicles, what is leaking chemical like oil. Also if that fungus will get the genetic transplant from the microbes, what is destroying oil, that thing would make them suitable for clean the oil damages.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low.  The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away.  When the box is filled with quantum gas and som...

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t...

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between  USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull.  The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting ...
