They discover microbes capable of creating their own oxygen, and without sunlight

Published

New research shows that some types of microbes that live in the deep sea are able to live without the need for sunlight and even without oxygen for quite a long time, where as they surprisingly verified in a laboratory with a sample obtained from the sea of ​​an ocean, they themselves are capable of generating the own oxygen they need to live.

For this, both Nitrosopumilus maritimus and ammonia oxidizing archaea (AOA) generate a biological process until now unknown, breaking all the beliefs held for years.

It was thought that the little oxygen that exists in the depths would allow them to stay for a time to fulfill a function, although the unknown is how they could be down so long without receiving sunlight, with little or no oxygen, and live in communities abundant, opened the doors to new research to answer it.

For the microbiologist Beate Kraft, from the University of Southern Denmark:

These types are really abundant in the oceans, where they play an important role in the nitrogen cycle (…) For this they need oxygen, so it has been a long-standing enigma why they are also very abundant in waters where there is no oxygen. We thought, do they just hang out there without any function? Are they some kind of ghost cells?

The researchers reproduced the conditions of the deep sea, without oxygen and without sunlight, to take a closer look at what would happen to them over time. What they observed caught their attention, and is that these microbes are capable of generating their own oxygen to create nitrite, with nitrogen gas (dinitrogen) as a by-product..

They still do not know the biological mechanism that allows them to generate their own oxygen, in relation to the process of generating oxygen without the need for sunlight that is known today, although they show that the amount generated is small although sufficient to survive

In the case of Nitrosopumilus maritimus, its oxygen production process is linked to the production of nitrogen gas.

In either case, the microbes perform this process to metabolize energy in a space lacking oxygen, generating their own oxygen, of which the researchers found traces of it along with that of the nitrogen gas by-product (N2).

This process removes the bioavailable nitrogen in the natural environment, being a novelty with the nitrogen cycle, which sustains all ecosystems, and this will lead to far-reaching consequences, which will need further investigation.

The research has been published in Science.

The first domestic mission to the Moon in 46 years will take place in September: the launch of the Luna-25 apparatus will take place from the Vostochny Cosmodrome

The first domestic mission to the Moon in 46 years

Director General of Roscosmos Dmitry Rogozin outlined the launch date for the Luna-25 spacecraft, which is to be launched from the Vostochny cosmodrome.

“Until the end of September, we plan to launch this device from the Vostochny cosmodrome,” said Dmitry Rogozin, speaking at the New Horizons marathon of the Knowledge society. Earlier, he said that the launch date will be determined based on the results of the tests.

The first domestic mission to the Moon in 46 years will take place in September: the launch of the Luna-25 apparatus will take place from the Vostochny Cosmodrome

Alexander Mitkin, deputy general designer for electrical systems at NPO Lavochkin, said earlier that the launch of the first domestic mission to the moon in 46 years from the Vostochny cosmodrome is scheduled for August 22. Even earlier it was planned that the automatic station “Luna-25” will go to the Earth’s natural satellite in July. Rogozin later clarified that the launch is scheduled for the third quarter of 2022.

The main task of the mission will be to develop the basic technologies for soft landing in the circumpolar region and conduct contact studies of a given area of ​​the south pole of the moon.

iPhone 13 and 13 Pro Max became the best-selling phones in the world

iPhone 13 and 13 Pro Max became the best selling phones

Analyst Francisco Geronimo of IDC reports that Apple’s iPhone 13 was the world’s best-selling smartphone in the first quarter of this year despite major supply issues.

IDC does not disclose the total number of devices sold, as well as the market share of phones. The company recalls that the iPhone 12 and iPhone 11 were the top-selling phones of 2021 and 2020, respectively, so the iPhone 13 was expected to perform similarly. The iPhone 13 retails for $800 in the US, offering an Apple A15 Bionic SoC, a dual camera setup, a 6.1-inch notched display, and iOS 15.

iPhone 13 and 13 Pro Max became the best-selling phones in the world

The 6.7-inch iPhone 13 Pro Max took second place in the first quarter of 2022, indicating that people are more than willing to pay more for a bigger screen, better camera, and longer battery life.

The 6.1-inch iPhone 13 Pro took a respectable fourth place, while the tiny 5.4-inch iPhone 13 mini failed to make the top five. The latter further explains the rumors about Apple’s decision to phase out the iPhone mini. Combined, the iPhone 13 family accounts for 84% of total iPhone revenue in the first three months of 2022. The rest of the revenue comes from the iPhone SE (2022) and older iPhone 12 and iPhone 11 models. Analysts believe that the iPhone 14 could be even more successful.

Two 6.1-inch iPhones from Apple made the top five last quarter. But perhaps more important is the fact that the 6.7-inch Apple Pro model is outselling the 6.1-inch version. So the next generation 6.7-inch iPhone 14 Max could be an extremely profitable model for Apple. It will offer everything consumers love about Apple’s regular bestseller, but in a larger form factor that will be much more affordable than the Pro line.

The entry-level Samsung Galaxy A12 ranked third in the first quarter, while the mid-range Galaxy A32 ranked fifth.

Xiaomi has announced a new 86 inch TV Promise high image

Xiaomi has released a teaser image of its new TV today. In the picture – the edge of the TV with the inscription “Pro” on a metal frame. The company’s marketers point out three features of this model at once, which make it possible to attribute the new product to the “Pro” category: high image quality, high performance and, of course, size. Still, 86 inches is not small.
