The updated version of the application WhatsApp for Android now has a "pass-through» (end-to-end) encryption, which protects the default messages from being intercepted and read by unauthorized persons. This was reported in the company's blog partner WhatsApp to provide this function Open WhisperSystems.
The idea of "through" encryption that the message is encoded in the time of shipment and can only be decrypted by the user who it is intended. Thus, even if unauthorized persons will be able to intercept traffic WhatsApp, then the message will get to them in encrypted form. Moreover, decrypt messages and can not formally representatives themselves WhatsApp, because they will not be available to encryption keys, and because they can not disclose the content of correspondence, even by the court.
LHCb collaboration reported the discovery in the course of the experiments at the Large Hadron Collider (LHC), two new baryons. Their findings the authors published in the journal Physical Review Letters, and briefly with them can be found at CERN.
The existence of the particle and Xi_b'- Xi_b * -, discovered by scientists, it was predicted by the quark model of elementary particle physics. According to this theory, all particles involved in strong (nuclear) interaction - hadrons are composed of quarks.
Although all now groan and gasp about nuclear weapons, submarines and stealth aircraft, modern war - this is usually the infantry on the ground. And the infantry small arms need.
Over the last hundred years in the nature of modern warfare occurred great changes, as an intense rivalry between the two countries has given rise to new, more deadly weapons systems. Aircraft, missiles, tanks, submarines and other inventions, which in 1914 was practically nonexistent, quickly occupied key positions in the armies of the world.
Just yesterday it seemed that the production of spare organs for our fragile body - entertaining fiction, which, who knows, maybe it is realized in the distant future. Today we are talking with a man, through which growing new organs to become a reality, and salvation for the first patients. No less surprising it seems that the most innovative transplant operations developed in the laboratory of the most advanced research in the field of regenerative medicine are not held anywhere, and we have in Krasnodar
The idea of travel inside the human body and treatment of complex diseases in this way, put forward by science fiction writers in the 50-60-ies of the last century, may soon become a reality. So researchers at the Max Planck Institute are developing micro-robots that can move freely through the blood vessels, delivering drugs into the body, or making any transactions.
Scientists are developing a grid of nano wires capable of pulling germs from the wound, thus speeding up the healing process. Novelty was devoted to the report presented at the 61st Congress of the American Vacuum Society, and briefly about her reports Science News.
Another use of carbon nanotubes, which have previously been used in a new light source, flexible super capacitors and sensitive sensors, found researchers at the University of Utah. With their help, a team of scientists led by Professor Ling Zhang created a prototype sensor for the detection of explosives, which is also suitable for the identification of drugs and hazardous chemicals, such as nerve agents.
China is an active stance on the issue of lunar exploration and colonization (see. Note "On the Moon rover landed Chinese Yutu"). By the end of this year planned testing of the space program, "Chang'e-5": UAV will have to collect samples from the surface of the Moon and return them to Earth. This task will be implemented as part of the launch vehicles "Chang'e-5" and "Chang'e-6". With the completion of the mission of unmanned lunar exploration, since 2017, specialists will determine the date of a manned landing on the lunar surface, after which will begin construction of the base on the moon.
The Japanese company Aerial Burton continued to improve its unique development of real 3D-display capable of reproducing an image directly into the air (see. Note "Aerial Burton 3D display is building a true three-dimensional image"). One of the priorities in the study was a reduction in the size of the installation, up to the placement in the trunk of a car-SUV. This is due to the fact that the company wants to commercialize the project and expand the production of such mobile units by early 2015.
As the developers say the application of the system is possible to signal in an emergency situation when there is a necessity to build the image seen at long range, in areas where it is impossible to find a suitable location for the normal screen. For example, it can be text or pointers, hovering in the air that will inform victims about where you can get food, where there are emergency supplies, or indicate a safe path to the evacuation.
Technology of the air volumetric images based on the ionization of air by means of a sufficiently powerful infrared laser, capable of producing pulses with a frequency of 1,000 times per second. These pulses come in the three-dimensional scanning optical system which reflects the laser beam and focuses it at the desired point in space. The energy of the laser light ionizes the air molecules, causing them to emit photons of light in the visible range, making a point of the space pixel lit three-dimensional image.
French ekstremal Zhissi Francois (Francois Gissy) set a new world speed record on a bicycle ride with a jet engine. Rider clocked up to 333 km / h in just 4.8 seconds. Participated in the experiment Ferrari car looked just a snail compared with a jet bike.
The event took place at Paul Ricard in the south of France last Friday. Rocket engine mounted on the bike was built by Exotic Thermal Engineering. Unfortunately, information about what kind of fuel system uses not disclosed. It is known that the power plant is about 560 horsepower.
Flying locks always excite the imagination of not only children but also adults. Ever since the novel Dzh.Svifta "Gulliver's Travels", where the hero finds himself in the flying city of Laputa Castle dreamed of flying to see a generation of people. With the puzzle game "Hoverkraft Levitating Construction Challenge" Flying castle can not only see, but also to build.
