The Bluetooth headsets are multi-use tools.



Do you know that the Bluetooth headset can use as an eavesdropping tool? In that case, the eavesdropper must only put the Bluetooth headset where the microphone is in the room. And then connect their laptop or mobile telephone to that headset. The requirement is that the blue tooth is in the range of that tool. 

The fact is that operators can use Bluetooth devices through the walls. Sometimes computers are accidentally connected to the wrong printers. And that caused embarrassing situations. If the attacker leaves the headband headset connected to the mobile telephone in the room. That thing makes it possible to record everything that happens in that room. 

And that kind of headset is one of the remarkable risks to privacy. There is a possibility. By hacking the Bluetooth headset. The hacker can target psychological warfare like subliminal commands to the victim. But even if that thing is not possible hacking the Bluetooth set can cause a situation where hackers hear everything that participants talked about in the meetings.

The next-generation headsets are using mixed reality. And that thing makes those systems even more effective than before. 

There are headsets where are small action cameras. They can connect to mobile devices or laptops. And that allows them to share experiences on social media. But those systems can also connect with military systems. Infrared cameras make it possible to see in the dark. The information that the camera sends can project into HUD glasses. Or in more primitive models to the screens of mobile telephones. 

In laboratories are also developed headsets equipped with laser microphones. Those systems can use as eavesdropping tools. The laser microphones can eavesdrop on everything that is talked behind closed windows. That kind of system can use as a super-tools for hearing things that not wanted to share with everybody. 

The laser system can also point the enemy tanks and other targets in the military world. So the operator must only look at the target and then use a gesture or button to mark it for the systems. The gesture can be that the person just shows the middle finger or some other mark to the same camera. 

The system can see the fingerprint and then mark the target's position.  The requirement for that system's successful work is that the system recognizes the mark. The system can use the GPS-connected rangefinder and radio compass to locate the target. . And then the image of the target will send to the entire system. Then the snipers or drones etc. can take the target out.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines.  The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
