The sphere of nanotechnology is still at the stage of its formation, however, more and more discoveries and research in this area have appeared recently. One such study, conducted by a team of scientists from the California Institute of Technology, demonstrated the ability of robots made from a single short strand of DNA to explore a molecular surface, lift specific molecules and transport them to a designated location.

Previous work by various researchers has successfully demonstrated the creation of such DNA robots using the DNA origami method, but for the first time it was shown that they are capable of collecting and transferring certain molecules.

The robot consisted of a body, a “leg” with two “feet” and a “hand” with a “hand”. To test the robots, the researchers developed a molecular surface measuring 58×58 nanometers. Pegs made of DNA strands were placed over the entire surface, complementing the “legs” of the robot. This allowed the robot to move in any direction on the board, jumping from one nanopart to another.

Six fluorescent molecules (three red and three yellow) were randomly placed on the surface, which the robot had to assemble into two color groups at two specific points on the board. It took 24 hours and one DNA robot to explore the entire surface. When the robot collided with the right molecules, it picked them up with its “hand” and continued to move until it got to the right place. At the same time, the robot consumed very little chemical energy. The developers say the process can be accelerated by increasing the number of robots on the surface.

They also note that this study is just a proof of concept for such technologies, and these DNA robots are not yet designed for use in specific areas, which, however, may be very numerous in the future.

Elon Musk is right: no fusion is needed. The future we won t have

Before mass thermonuclear power engineering 20 years – and always will be 20 years. This simple joke itself became old 20 years ago. Society is upset that thermonuclear still cannot be brought to an industrial level. And only Elon Musk believes that a thermonuclear reactor is not needed at all. A careful analysis shows that he is right. Even if all the technical problems of thermonuclear energy are miraculously resolved, it will have no chance of ousting competitors. How did it happen, and what then will save humanity from the energy crisis?

In South Africa, discovered the remains of the oldest archaea on Earth

Fossils over 3.4 billion years old may be the remnants of archaeal microbes that lived and produced methane from hydrothermal vents at the bottom of the fossil sea.

An ancient inhabitant of a cave in the Caucasus turned out to be a carrier of the gene of the modern Western Eurasian population

An international team of scientists identified DNA from soil in a Georgian cave. Thanks to this, the researchers managed to restore the human genome 25 thousand years old, without having any skeletal remains.

Eleven-year-old child prodigy decided to become immortal and received a bachelor s degree in physics

A teenager from the Belgian city of Ostend became the second youngest holder of higher education in the foreseeable history. He graduated with honors from a physics course at the University of Antwerp and is now going to defend his master s degree and then his doctoral dissertation in this field. His goal is simple and clear: increasing the life expectancy of a person up to complete immortality by replacing body parts and organs with mechanical or artificial ones.
