For its first billion years, it was a hostile, harsh, rocky place where life did not exist. According to research, the first living organisms appeared in Earth's oceans about 3.5 billion years ago.

This is established on the basis of phyologenesis (origin), biochemistry and anatomy. Fungi are reco ...

With many plants, they form mycorrhiza (symbiotic association of roots or seeds of vascular plants w ...

Silver is the only catalyst that allows the conversion of ethylene into ethylene oxide, which then undergoes hydrolysis to produce ethylene glycol, used to produce polyester.

It interacts with visible matter only gravitationally and remains invisible and undetectable in any other way. It is estimated that 90 percent of the mass of the Milky Way is dark matter.

This is a major obstacle to graphene finding mass application in many fields. For now, only small amounts are produced.

It was launched on 14 April 2023, and is expected to reach Ganymede in December 2034.

On its surface, there are both geologically young areas and much older, darker, and covered with many craters.

Taking too large doses of such silver may lead to argyrosis, and discoloration of the skin, eyes, and mucous membranes to a blue-gray color, which is an irreversible process.

As a result, diamond is a transparent, non-reactive insulator, and graphite is a black conductor, susceptible to chemical modifications.
