1 Astronomers were able to detect for the first time signals related to the appearance of the first stars 13.6 billion years ago, shortly after the birth of the Universe, according to a study published in the journal Nature.

The author of this exploit is a small radio telescope installed in Australia, whose antenna has the width of a refrigerator.

However, the discovery still needs to be confirmed by other researchers and other more powerful instruments.

2 Japan is experimenting a new farming technique that will produce salmon profitably so that the Japanese can eat locally grown fish: raising salmon in a large pool of water.

Salmon consumption has exploded worldwide since the 1980s, especially in the United States, Russia, Europe or Japan.

To meet this demand, livestock has gradually supplanted the fishery. It is mainly practiced in farms located at sea but it is difficult in Japan because the waters are too hot during the summer.

3 Vodafone and Nokia will develop a 4G cellular network to work on the moon. It will be used to broadcast images in HD during the mission of PTScientists group scheduled for 2019.

PTScientists is a group of scientists and engineers based in Germany who participated in the Google Lunar X-Prize contest. Last year, they announced Mission to the Moon, a program that plans to search for the abandoned vehicle by NASA astronauts Eugene Cernan and Harrison Schmitt during the last inhabited lunar mission Apollo 17.
