Seminar topics: Scientists have succeeded in implanting live electrodes made of genetically modified neurons to respond to light in the brains of mice .. The launch of a small satellite in early 2021 is testing a new method for tracking satellites in orbit using light-emitting diodes to prevent space collisions. From an orbiter around Mars for the first time, the presence of water in the upper layer of the atmosphere indicates a more efficient process that could lead to more water being removed from the planet.
Scientists have successfully implanted live electrodes made of neurons genetically modified to respond to light in the brains of mice. The plan hopes to provide a better, longer-term way to connect brains to computers than conventional electrodes.
The launch of a small satellite in early 2021 tests a new way to track satellites in orbit using light-emitting diodes (LEDs) that flash to send their position to Earth.

In this episode, we also talk about music and what makes the ears attract to it and distinguish it, as well as the elements that are included in the composition and what makes a successful melody in relation to the author’s style .. and the difference between the elements of noise and the organization of music.
In this episode, we also recall from the memory of science the biography of the physiologist Ernst Starling, who discovered hormones and gave them this name.
