Jacob Bogatin: Japanese scientists approached the use of fusion energy

For a long time, scientists have been trying to create conditions for a stable controlled reaction of thermonuclear fusion. However, the production of such a reactor is fraught with a lot of difficulties, and even the most ambitious project in this field ITER (International Thermonuclear Experimental Reactor) was postponed until 2025. But help can come from physicists from the University of Tokyo, which, according to the publication ScienceAlert, have become one step closer to using the energy of thermonuclear fusion. They first managed to create a magnetic field with entirely controlled parameters, says Jacob Bogatin.

This was necessary because one of the ways to launch a self-sustaining thermonuclear reaction is to hold the compressed high-temperature plasma and its charged particles to raise the overall temperature of the reactor. This method is called EMFC (electromagnetic flux-compression), or “electromagnetic flow compression.” The device developed by the Japanese scientists is capable of producing a magnetic field by force in 1200 Tesla, Jacob Bogatin remarks.

During a series of experiments, Japanese physicists managed not only to create such a field but also to make it work for 100 microseconds. Yes, this is not a very impressive result, but it is still many times greater than all previous indicators. At the same time, which is also very important, during the operation of the new installation the elements of its design are not subject to destruction and change under the influence of its own magnetic field, says Jacob Bogatin.

Jacob Bogatin: Google accused of slowing down YouTube in third-party browsers

Specialists of the company Mozilla caught Google in the deliberate slowdown of YouTube, which operates in third-party browsers. This is due to the use of the Shadow DOM v0 API service, which is supported only in Chrome, says Jacob Bogatin.

According to the manager of technical programs of the company Mozilla Chris Peterson, the speed of YouTube in the browsers Firefox and Microsoft Edge is about five times lower than in Chrome. The expert is sure that the reason for slowing the work of the portal in third-party web browsers is due to the use of the Shadow API DOM v0 service, which is supported only in Chrome, expert Jacob Bogatin says.

Shadow DOM v0 appeared on YouTube only recently. It was added during one of the last redesigns, and this is the key to solving the problem. Chris Peterson in his tweet advises Firefox users to install the YouTube Classic extension. It returns the previous design of the site and disables the Shadow DOM v0 API.

Recall that last week the European Commission fined Google nearly $ 5 billion for the fact that the American Internet giant required smartphone manufacturers to pre-install its services, namely the search service and Chrome browser. Will the story with the slowdown of YouTube the reason for new sanctions against the company, time will tell, said Jacob Bogatin.
