Microbes as part of biodiversity in space flights
Astronauts arriving and returning from space stations carry trillions of microscopic organisms with them. For example, new species of space-adapted bacteria have been discovered on China’s Tiangong space station. Recently, 26 previously unknown species of bacteria were discovered in NASA’s cleanrooms—some of the most sterile environments ever created by humanity. Another study shows that, under stress, strains isolated from the ISS mutated and became genetically and functionally distinct from their terrestrial counterparts.
Heavy hydrogen used in nuclear energy and water turned out to be older than Earth
In protoplanetary disks, water is virtually omnipresent. Recent studies of the water content of early planetary systems like ours show that water is an abundant and ubiquitous molecule, originally synthesized on the surface of tiny grains of interstellar dust by hydrogenation of frozen oxygen, reports the journal Elements. In the molecular cloud from which a new planetary system will emerge, oxygen attaches and freezes to the dust grains it encounters. Once a hydrogen molecule intersects with this frozen oxygen, water ice is formed.
Hydrogen rush: the world is in full swing with the introduction of new hydrogen fuel
More than 1 thousand projects in the field of hydrogen energy have been announced worldwide, totaling more than $320 billion, according to Reuters. The German government will also subsidize pure hydrogen power plants of up to 500 MW for energy research purposes. Hydrogen gas power plants are expected to help Germany move away from coal entirely by 2038. Hydrogen deposits could power the world for hundreds of years, according to the US Geological Survey.
