A famous American businessman, public figure, philanthropist, and one of the founders of Microsoft, Bill Gates, said that the media often lie about the fact that life gets worse, in pursuit of attention.
This is discussed in his column for Time, the Observer reports.
In his opinion, the modern world and society are improving and getting better. However, journalists too exaggerate, covering the world events.
Gates argues that humanity is moving in the right direction - from reducing child mortality to protecting the LGBT community. He stressed that the proportion of people living in extreme poverty is declining, and more than 90% of children around the world are educated.
At the same time, the philanthropist continued, the media create too disturbing a situation, overreacting with negative news and excessively thickening colors.
"Bad news attracts attention, good flies by," Gates writes.
Despite this, the entrepreneur believes the fact that negative stories attracted increased attention, inspiring hope in humanity.
However, even without good, inspiring news, positive examples and heroes, there will be no hope, he continued.

At the very end of last year, representatives of Fujitsu announced the development of a process for the production of sheets of material consisting of multi-walled carbon nanotubes. These nanotubes are located perpendicular to the plane of the material and it is in this direction that this material has the highest thermal conductivity to date. Products from such a nanotube material formed in a certain way can act as an effective heat sink for electronic devices, including silicon carbide power devices used in modern electric cars.
According to the results of the tests, sheets of nanotube material are able to conduct and dissipate heat with an efficiency of 80 Watt per meter per degree Kelvin. This is about three times more thermal conductivity than the thermal conductivity of sheet indium, a material used in some areas to provide high-efficiency cooling.
The biggest problem successfully solved by Fujitsu specialists was the problem of growing carbon nanotubes of uniform size by the chemical vapor deposition process. After all, with the slightest deviation from the norm of any of the parameters of this process, nanotubes of various sizes and specific densities begin to "grow" on the surface of the metal substrate. This is the problem that prevented the technology of large-scale production of sheet nanotube materials for a long time. The material structure The specialists of the laboratory of Fujitsu Devices & Materials Laboratory have developed a new process that allows to accurately control the temperature and pressure of gas in a chamber where the process of depositing nanotubes onto a surface on which particles metal catalyst. All this leads to an increase in the "forest" of homogeneous nanotubes, located strictly perpendicular to the base. The dimensions of the sheets of material that can be produced in this manner are limited by the dimensions of the base preparations and are equal to 200 millimeters.
The material, consisting of multi-walled nanotubes, which after cultivation undergo special chemical treatment, can withstand heating to a temperature of 700 degrees Celsius. This is much more than the capacity of sheet indium, the melting point of which is about 160 degrees.
Fujitsu is going to commercialize this technology by 2020. But before that time they will have to solve the problem of the high cost of new material, which far exceeds the cost of traditional materials used as a heat sink. This, first of all, can be achieved by improving the technological process of production of such material. But even without a drastic reduction in cost, such material can already be used in space technology, in high-voltage power electronics and in other areas where costs do not play a major role and where effective cooling of devices operating at temperatures of 200 degrees Celsius and above is required.

The company Panasonic, known throughout the world for its advanced technology, announced the premiere of its first concept car.
The official presentation of the autonomous electric vehicle will be held within the framework of the international exhibition of techno-innovations CES 2018 in Las Vegas, which will begin on January 8. Experts expect to see something unique - something that no one else has done.
It is likely that the concept car will be equipped with its own unmanned driving system from Panasonic, capable of reading not only the environment and road signs, but ultrasonic sensors.

A group of American scientists has achieved significant success in creating a "quantum radio", whose capabilities far exceed the transmission of the GPS signal, as well as the specifications of cellular communications.
American specialists managed to create an apparatus capable of transmitting signals without crossing the boundary in 1pt, and also working at a frequency lower than 1 kHz. According to the developers of this system, this device can send both audio messages and video files. Scientists have noticed that the specifications of this device allow using it for communication with various hard-to-reach regions that do not have cellular coverage.
A key feature of the present invention is that the use of magnetic waves is widespread throughout science, however, before this apparatus people did not attempt to transmit video or audio messages using such waves. Note that signals with the help of the invented device are also freely transferred underwater.

Apple has absorbed the Canadian service Buddbuild. The deal was officially announced on January 2. Developers will remain on the territory of Canada, but will become part of the Xcode team, which creates tools for iOS, macOS, watchOS and tvOS.
With Buddibuild iOS- and Android-developers can collect feedback from users, quickly make changes to the code and update applications. The service is integrated with GitHub, Jira, Slack, Trello and other popular tools.
After the deal with Apple, the platform will no longer support development for Android. In addition, the creators of Buddybuild will stop the development of the product and restrict registration: the service will be available only to existing users. Among them are teams from Mozilla, Hootsuite, Reddit, Soundloud, Foursquare, and The New York Times.
Buddybuild was founded in 2015 by two former employees of Amazon - Dennis Pilarinos and Christopher Scott. In May 2016, they raised $ 7.6 million. The investment round of the A series was led by the Kleiner Foundation, Perkins, Caufield and Byers. In just three years, the company raised $ 8.8 million.
