A group of Japanese scientists has designed nanomotors working by changing the conformation of the DNA molecule - the transition from the double helix pravozakruchennoy (B-form) in the left-twisted (Z-form). "Run" is the motor by changing the concentration of ions in solution. Securing the motor in a rigid frame that fixes it to the substrate, not interfering with the rotation of the rotor, the scientists managed by atomic force microscopy to monitor the operation of the engine in real time. They fixed two turns of the rotor, which is one BZ-transition.Fig. 1. Top: scheme of rotation Read more [...]

The program HELLADS, supervised by the agency DARPA, is to create a 150-kilowatt laser weapon system, which will be ten times smaller and lighter than existing laser of the same capacity, and can be integrated into tactical aircraft for defense and attack ground targets. Aiming to get a device with a specific gravity of less than five pounds per kilowatt of power, and volume of three cubic meters, HELLADS can be integrated into the aircraft, significantly expanding the radius of defeat compared with terrestrial systems.
As part of the laboratory tests were a key element of the system - the laser Read more [...]
It seems to supply a lunar base in the U.S. is preparing thoroughly: robots that support its operation, recently advertised one by one.Besides the "lunar porter", NASA engineers, as it turns out, are developing lunar miner and gruntovoza.The problem is the same: low gravity, indicating a weak grip. Regolith Advanced Surface Systems Operations Robot Excavator (RASSOR Excavator) designed in a somewhat unusual way: to solve the problem of friction, it uses something closer to circular saws (or front roller MTT), than the wheels. They are a single unit mounted on three pairs for each Read more [...]
Future lunar base should be provided with water by means of "hunting" on the small comet, each of which may contain hundreds of tons of water ice - it's easier and more efficient than production of ice in the polar regions of the moon, according to the Institute of Astronomy of the Russian Academy of Sciences Alexander Bagrov and head of the St. Petersburg KB "Arsenal" Michael Kislitsky.Data obtained with robotic probes in recent years have shown that in the polar regions of the moon, which is almost never looks the sun, can be hundreds of millions of tons of ice.

Adhesives, coated with microscopic needles 250 microns wide and 650 microns long, can introduce a DNA vaccine into the body. Such vaccines can help develop immunity against several diseases.The meaning of such vaccines is to familiarize the body with the genes of pathogens. The cells produce molecules grafted human pathogen, which signals the immune system of the aliens. DNA vaccines are more beneficial than usual. For example, do not need to spend time on the production and purification of proteins from pathogens. In theory, all make the body itself. Scientists have tried many times to increase Read more [...]
In the next seven years at the disposal of U.S. authorities go 30,000 drones that will monitor citizens. In order to keep people's privacy intact, Adam Harvey, a designer from New York, has developed a new line of clothing, which helps to hide from surveillance.
Scientists are one step from being able to identify portraits that hide behind the visible image on the canvas of Rembrandt.
The painting "" Portrait of an old man in military costume ", painted by Dutch artist Rembrandt is in the Getty Museum (J. Paul Getty Museum) in Los Angeles. Scientists have noticed that the painting is a portrait of the other tracks, hiding behind the surface of the ground. Initially, the researchers tested the picture using infrared, neutron and X-ray conventional methods. But they could not see what is behind the main layer as Rembrandt used a paint with Read more [...]
A new method of vaccination, similar to a temporary tattoo, allows you to enter the DNA vaccinated absolutely painless and with long enough to immune cells learned about pathogen.Researchers from the Massachusetts Institute of Technology (USA) to develop a vaccine that does not need to stick a syringe and stored under certain conditions, and in addition, it does not cause a person any discomfort.This vaccine, in contrast to most of today, uses no viral proteins or bacteria that you want to teach the immune system, and DNA. DNA vaccines in recent years have increasingly attracted the attention Read more [...]
SpaceLiner, presumably, be able to throw fifty passengers from Europe to Australia in 90 minutes - or 100 passengers from Europe to California in an hour. To do this, it must accelerate to M24 - more precisely, up to 25 200 km / h, and at altitudes up to 82 km. The passenger cabin is fully concentrated in the bow. (Here and below illustrate the DLR.) "Maybe we better characterize SpaceLiner, saying that it is a kind of second generation Space Shuttle, but with a totally different challenge," - says Martin Zippel, Project Coordinator German aerospace center (DLR). German developers Read more [...]
Imagine a future space station, which allows astronauts to get energy from the sun and produce minerals from asteroids, then to use them to sustain life. As it turns out, is not just a dream but real plans of Deep Space Industries. It plans to start production of hydrogen, oxygen, iron, and nickel from space objects, to provide fuel and satellites in orbit to conduct building. Its first task - to 2015 went into orbit vehicle "Firefly." The device will land on one of the near-Earth asteroids, and within six months will be to conduct research and collect data.
