Scientists were able to revive microbes living in “hibernation” more than 100 million years

10 years ago during the expedition to the Pacific vortex between Australia and South America, considered the most remote from the nearest land, scientists drilled into the seabed a series of 100-meter wells and brought to the surface a few sediment cores. It should be clarified that the depth of the ocean in this place of about 6000 m.

What happened then can rightly be considered as a sensation: in sedimentary rocks was discovered “sleeping” micro-organisms that lived on Earth over 100 million years ago.

According to one of the leaders of the study of Yuki Morono from the University of Rhode island (USA), scientists were interested in two main questions:

  • is there life in such a limited nutrient environment or it is not there?
  • how long microorganisms are able to survive in conditions of almost complete absence of food?

Later they found in all the cores the oxygen, and this means that the precipitate was formed gradually, allowing oxygen to seep through the rock. Due to this the microbes alive for tens of millions of years. After extraction, the microbes were placed in a nutrient medium, and almost all of them came to life.

Given the limited resources, the metabolism of these organisms proceeds much smoother, they are much slower evolyutsioniruet, which is understandable: their energy is barely enough to maintain existence.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
