How to deal with a routine of war and how to preserve the children's optimism?

The surprise and speed with which things happened, and the ignorance regarding the fate of many people, arouses tension and distress in all of us. Bar-Ilan University's mental support team offers several ways to help us deal with
Clusters of satellites, such as the BlueWalker 3 prototype, are causing concern among astronomers due to possible interference with night sky observations and radio astronomy. Balancing the global needs for communication and maintaining astronomical research is critical. Credit: AST SpaceMobile

A prototype of a large low-orbit communications satellite is troubling astronomers

The BlueWalker 3 satellite whose antenna area is 64 square meters has become one of the brightest objects in the night sky, the fear is that when there are a hundred satellites in this constellation and hundreds in other constellations it will be impossible to watch the sky

Voyager 2 has lost contact with Earth. Only one radio dish in the world can help her "call home"

A human error in the commands sent to her caused her antenna to tilt at an angle of two degrees from the Earth. The radio antenna engineers of the deep space network in Australia will try to contact her
The picture shows an energy band diagram of a micro-resonator based on a GaAs semiconductor as studied in the experiment, in which a quantum condensation of light-matter coupled quasi-particles called exciton-polaritons (exciton-polaritons) - through two-photon absorption. The achievement paves the way for new coherent control schemes and the realization of an efficient laser source in the terahertz (THz) range of electromagnetic radiation

First observation of "two-photon absorption for quantum condensation"

The achievement may accelerate research in new quantum technologies and developments in security, biological sensing, wireless communication and more
