The robot water striders are the fastest and smallest miniature robots.

"Researchers at Washington State University have developed the smallest and fastest micro-robots, potentially transforming fields from artificial pollination to surgery. Utilizing shape memory alloys for movement, these robots—significantly lighter and quicker than previous models—aspire to achieve greater autonomy and efficiency by mimicking natural insect behavior.

The new miniature robots can walk on the water. Their structure is a straight copy of the water striders. The small bugs that can walk or slide on the water. On the water strider's feet is small hair and their weight is divided on the layer so that it will not fall through the surface membrane.

This system, that the Washington State University created uses small rows to move the robot. So the robot stands on water. And the rows move it. Another way is to use small-size paddle wheels that can make those robots even faster. In some visions on those robot's feet small cylinders can rotate and push the robot forward.

The more advanced system can use the small nano-hair that makes it hover above the water layer. And some models can have nano-size paddle wheels where those small nano-hairs can be in rotating platforms. Those rotating paddle wheels can give those robots more speed than any natural water strider can get.

The smallest and fastest miniature robots in the world are the next-generation tools for scientific and military applications. This type of miniature robot can sniff chemicals, observe their environment, and search for new species. In the same way, those systems can operate in civil rescue and military intelligence missions.

The bug-size robots are possible because they can harvest energy from radio waves. However, there is the possibility. Some next-generation robots use biological power units like living cells that can create energy for the system. The new types of microchips can use living neurons to boost their abilities.

And those systems can be the tools that give small robots to very high autonomy. The tiny robots that use biological electric delivery systems and biological microchips can eat similar nutrients to vegetables and humans. So those systems can be the next-generation invisible tools for many missions.

"Researchers at the University of Cordoba, in collaboration with other institutions, have developed a new type of battery using hemoglobin as a catalyst in zinc-air batteries. This biocompatible battery can function for up to 30 days and offers several advantages, such as sustainability and suitability for use in human body devices. Despite its non-rechargeable nature, this innovation marks a significant step towards environmentally friendly battery alternatives, addressing the limitations of current lithium-ion batteries.

The "robot mosquito". The hemoglobin batteries.

Things like hemoglobin batteries are exciting systems. The system can use living cells to make hemoglobin for those batteries. The hemoglobin battery base is similar to all other batteries. Electrons travel from hemoglobin iron to the more noble metal. The thing with that battery is that it must replace used hemoglobin. And one thing that can make this thing is biotechnology where the bone marrow makes new red blood cells to those batteries.

And finally, the internal cell cultures in larger-size robots can produce methane that the system can use in its fuel cells. The system can use any type of organic material that is closed in an anaerobic chamber. Then that methane can be driven to the fuel cells. Or there is a possibility that the system uses electric eel cells for making high-voltage power. As I wrote many times before the new biological systems can connected into parallel and serial connections. And they might be less powerful than isotope batteries. But those biological systems do not involve radioactive material that can be dangerous in the wrong hands.

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 th

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology. Could a hypothetical Planet X tunnel all radiation? The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory. And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact. In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells. Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche
