Scientists launched the first large quantum network connecting 200 users over distances up to 200 km. The secret of protection lies in the behavior of two photons at a half-silvered mirror: if they are perfectly identical, they always go through together. It's like a turnstile that opens only for a

A solar magnetic loop, twisted by 540 degrees, snapped at one end alone, spewing hot gas and hard X-rays. This proves that magnetic reconnection accelerates particles and heats the corona. Scientists found a pattern: the frequency of plasma pulsations directly indicates the strength of the magnetic
