The US Justice Department is using "feykovye" cell tower on airplanes to get free access to registration data from the phones of almost all the country's population.

As told WSJ anonymous sources familiar with the secret program the US authorities, the technique of shadowing fully operational since 2007 and identifies the location of any phone with an error of only three meters.

It is running the whole system like this: on the aircraft (the most commonly used small civilian aircraft company Cessna) installed special equipment - stuffed with electronics boxes in the shape of a cube. Square faces boxes are 0.6 meters in length, but the relatively small size does not prevent them to play the role of full-fledged cell phone towers.

Aircraft with these devices is then lifted into the air. The operation uses five (at least) the major airports, and their location, coupled with a range of aircraft flight ensures contact with the phones of almost all of the US population.

"Towers" can analyze thousands of active phones, simulating a strong signal. Since modern mobile phones are designed in such a way that automatically selects the strongest signal, then fall into the trap and select signal "tower" on the plane.

As soon as the connection box on an airplane gets access to the phone of equal access of the cellular operator: he becomes the registration data phone, including highly valuable information to the authorities about his whereabouts.

According to sources the WSJ, this technique is only used to spy on suspects and criminals, but "towers" in the process of receiving data from thousands nothing to do with this or that operation of phones that just looking to identify the signal of the desired phone.

Saved if the data in the device memory, and some established control over their use - is unknown. Departures equipped aircraft occur regularly.

The Ministry of Justice at the request WSJ information to confirm or refute. A ministry spokesman said only that the discussion of these issues can be declassified US intelligence opportunities for criminals and foreign powers, and all ministries projects do not go beyond US laws.

From the article the WSJ, however, that if this program really exists, its use violates the country's constitution. 

 iPhone will measure in at 137.54mm tall and 67.54mm wide.The iPhone 8 is set to come with an all new design, wireless charging, an OLED display and more.

The schematics also point towards the device sporting a 5.768 display which is bigger than the iPhone 7 Plus's 5.5-inch panel. The 2.5D display is rumoured to cover the entire front panel with the side bezels measuring as low as 4mm at their thinnest point.

 But according to analyst Timothy Arcuri of Cowen and Company, the company is apparently facing a lot of issues in ramping up yield rates of the new sensor and because of that it might be forced to abandon the radical approach and make do with a more traditional fingerprint sensor instead.

we can see a vertically mounted dual camera setup. This design has been doing the rounds of the internet lately and seems to be more or less a given now. According to Ben Bajarin, the position of the LED flash in between the two camera lenses is supposedly to help facilitate 3D features and augmented reality.

 iPhone 8 will come with an OLED display, an Iris Scanner like the one found on the Samsung Galaxy S8, IP68 dust and water resistance, 3D cameras and a Smart connector for accessories such as a VR headset.

The ‘Enablement’ platform and its suite of customized products provide end customers in many specialist vertical markets with the tools to easily embed IoT into their business, rapidly exploit the benefits and continuously evolve to their demands and desires.

Scientists have figured out how to change the crystal structure of the cathode in lithium-ion batteries to significantly improve the efficiency and extend the life without compromising security. The study is published in the prestigious journal Nature Materials .

Lithium-ion batteries are commonly used as the primary source of energy in modern portable equipment - laptops, tablets, mobile phones and cameras. Lithium is the charge carrier when the battery is charged, lithium ions leave the crystal lattice of a mixed oxide of a transition metal, capable of changing its degree of oxidation. In modern batteries typically used, cobalt oxide and layered lithium.
 

The crystal structure of the layered cathode material LiCoO 2

Two basic characteristics of a lithium-ion battery
- the number of charging cycles and the capacity (amount of lithium leaving the crystal lattice during the charge and returning back at discharge). The problem is that all of the lithium never leaves the cathode structure (not more than 60%). Otherwise, increasing the likelihood of an explosion and a fire. Are finite and the number of recharge cycles (the energy contained in the charged batteries decreases with time).

Scientists have found a solution to these problems. They suggested that other crystalline structure of the cathode material. Classical lithium-ion battery has a layered "structure" in which the lithium layers are interleaved with layers of oxygen and a transition metal. At that time, when Li is leaving his position, his place is taken by transition metal ions. Therefore, to come back, he could not - his place is already taken. As a result, the battery capacity decreases.

New battery structure suggests a shift layers relative to each other, so that the battery gets skeleton structure and is much more stable: almost no energy is lost. This makes it possible to extract from it all the lithium when charging. It is not the risk of fire occurs.

"Previously it was thought that the capacity of the lithium ion battery is determined by the change in the degree of oxidation of the transition metal included in its composition. In one of our previous work, we showed that oxygen can also contribute to the battery capacity, it increases it due to the fact that its degree of oxidation is also changing. In our new study, we have demonstrated a way to use this capacity to the full, without fear of explosions, fires and degradation of materials, " -  commented Professor Skolkovo Tech Center for electrochemical energy storage Artem Abakumov.

As long as the "concept" of the sample, researchers used a lithium compound with an oxide of iridium. But this option is expensive, so its mass production is inefficient. A further objective of specialists - find better and more cheap metals.

Rare: Snake Charmer caught two 4-foot cobra with his bare hands and removed their fangs - Fearless Indonesian snake charmer caught two 4-foot king cobra with his bare hands and removed their fangs. These beasts can kill an elephant in one bite! 22-year-old Roni Kurniawan (Roni Kurniawan) from the Indonesian province of Riau fearlessly operates two king cobra and is not afraid to keep the snakes are literally a few inches from his face.

 Fortunately, scaly lack fangs and they can not injure a human being. Snakes terrorize the local village. Local residents appealed for help to Rony, who is known in the neighborhood as a snake charmer. Fearless caster successfully caught creeping reptiles and deprived of their teeth. One of the cobras, which received the nickname of Ice (Ice), after being deprived of its poisonous teeth, managed to bite the caster, but Roni compared the attack with "sting". King cobras can reach a length of up to 5.5 meters and live in the wild and 20 years. Roni was the snake charmer as a teenager and now earns a living with catches snakes that climb into human dwellings. King Cobra today - the longest venomous snake in the world. Its venom is not the most deadly among venomous snakes, but one bite of it contains up to two-tenths of a gram of venom. This is enough to kill 20 people, or even an elephant. Venom is a neurotoxin that attacks the nerve cells. bitten prey paralysis occurs very quickly. The king cobra is able to raise up to one third of the length of his body when an impending attack or threatened her life. In addition, it can pursue its prey for some time in the upright position. When the kite is in this position, it can reach the vertical height of 1.8 meters.
