New Concept: The Earth’s Longest Oxygen Days Begin

Scientists have a new idea of ​​how the earth got oxygen – because the planet has shrunk and days have elapsed. A study published Monday shows that long, continuous daylight swamps produce a lot of oxygen, which, as we all know, gives life to most bacteria.

They figured out how much light they had obtained in the laboratory by boiling fine purple bacteria in a deep pool in Lake Hauro. With continuous light, scented microbes produce more oxygen.

One of the great mysteries of science is simply how the earth has moved from the low-oxygen planet to the atmosphere. Scientists have assembled cyanobacteria, but they have not been able to determine the origin of the great oxygen phenomenon. In a study conducted by researchers on Monday Nature Geoscience The slow motion of the earth, which gradually extended from six hours to 24 hours, was the key to cyanobacteria, which was the key to the planet’s ability to breathe more.

2.4 billion years ago, there was so little oxygen in the atmosphere that it could not be measured, so no animal or plant life could exist as we know it. Instead, many microbes breathe in carbon dioxide, and in the case of cyanobacteria, they first produce oxygen in the form of photosynthesis. At first it was not so much, but in just 400 million years the Earth’s atmosphere has reduced our current oxygen content to one-tenth — a big jump, lead author of the study, Max Planck Institute of Biogeochemistry in Germany. That oxygen explosion has helped improve plants and animals, he said, adding that other plants have now joined the Oxygen Maker Party.

But why do bacteria carry so much oxygen? That’s where Brian Arbeck, an oceanographer at the University of Michigan, came in. It studies how the earth’s magnetic field and the earth’s magnetic field are reduced. Arbic was listening to his partner’s talk about binoculars and noticed that the oxygen phenomenon coincided with the longer life of the earth.

Due to the complex physics of wave collisions and the interaction with the moon, the speed of the planet’s rotation slows down. Michigan and German researchers have experimented with theories of bacteria similar to those of 2.4 billion years ago. Lake Haron used purple and white cyanobacteria mats in a world of 79 feet[24 m]deep.

“For most of its history, the world is like a swimming pool for most of the Middle Island,” Clat said. Various people brought carpets of bacteria that smelled like rotten eggs. Clat and his colleagues were exposed to different levels of light, up to 26 direct hours.

More constant light causes microbes to produce more oxygen. The authors and foreign scientists say that this is only one possible explanation for the increase in oxygen levels. Not surprisingly, it does not require major biological changes in bacteria or the world’s oceans, says Tim Lyon, a professor of biochemistry at the University of California, Riverside, who was not part of the research team.
