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.
Melting permafrost could release nuclear waste and pathogens
A team of scientists has discovered that thawing permafrost could release a dangerous legacy of the Cold War – nuclear waste that is still radioactive. In addition, the release of pathogenic microorganisms is possible, reports Nature Climate Change. Melting Arctic glaciers could release radioactive waste from Cold War-era nuclear submarines and reactors. The Arctic’s nine million square miles of ice have been accumulating for more than a million years a variety of substances that could be released into the air and water due to climate change.
The threat of nuclear war looms over humanity
Russia and China may overtake the United States in the number of nuclear weapons. This was stated by the head of the Strategic Command of the US Armed Forces, Air Force General Anthony Cotton. Earlier, Russian President Vladimir Putin, during a meeting with participants of the “Everything for Victory” forum in Tula, said that Russian strategic nuclear forces have been almost completely updated. Moreover, their marine component is almost 100%.
