Japanese scientists revive microbes buried in rocks more than a hundred million years ago

New Delhi: Japanese scientists have managed to revive sediment microbes in the South Pacific dating back more than a hundred million years.

Samples of ancient sediments under the seabed help scientists perceive beyond climates and the deep marine ecosystem. Since then, the continents have changed, the seas have risen and lowered, and yet human beings have evolved.

Thanks to the subtle laboratory procedures, scientists revived these microbes and convinced them to multiply. The effects show that, instead of being fossilized life remains, the microbes of ancient sediments have survived and will be reborn under the right conditions. More on the BBC.

A well-known archaeological in southern Sweden, known for its abundant amounts of bone and flint, has suffered a drastic deterioration since the 1940s.

Last year, researchers found that bone fragments discovered in the region had suffered rapid deterioration over the past seven decades. More worryingly, scientists can no longer locate small bones of furry animals or birds. Small mammals and birds have smaller, lighter bones that break down faster than heavier bones.

Archaeologists say that if no action is taken at the site, the biological remains preserved here for 9,000 years will be lost forever. Destroyed registry is also a long-term database that can help us model long-term environmental scenarios. This can be especially useful now when the Earth is in the midst of a climate crisis.

Scientists have begun to expand the global nuclear fusion project, known as the International Thermonuclear Experimental Reactor or ITER.

The facility, in France, is financed and controlled through seven member entities, adding India. The European Union, China, Japan, Russia, South Korea and the United States are also components of the project.

The concept is that it works like a star, acting the same type of fusion reactions that occur in stars, resulting in giant amounts of energy. The reactor designed to produce a capacity of 500 MW with an input of 50 MW, resulting in a gain of ten times.

All member entities contribute to this project. India’s biggest contribution will be the cryostat, a device used to keep the temperatures around the entire machine low.

At the end of the allocation, India will also need to acquire ownership rights to build its own fusion reactor. The task meeting is expected to be completed in five years. Learn more about The Guardian.

A mysteriously long, thin cloud has reappeared over a top 20 km volcano on Mars. According to the European Space Agency, this long-weather cloud bureaucracy every Martian year this season, and is repeated for 80 days or more.

A Martian day, or land, lasts approximately 24 hours, 39 minutes and 35 seconds. A year on the red planet consists of about 687 Earth days, so the seasons on Mars last twice as long as Earth’s.

Scientists are convinced that these appearances of clouds are not similar to volcanic activity. The cloud is made of water ice and can reach up to 1800 km in length.

Photographs of the clouds were taken on July 17 and 19 via a camera aboard the Mars Express, a European spacecraft that has been the red planet since orbit for 16 years. Learn more about CNET.

An Australian team discovered a collection of ancient stars that were probably plucked from our own galaxy, the Milky Way, more than two billion years ago.

This collection of stars, or ‘globular cluster’, is different from others because these stars  have much lower quantities of heavier elements than in other such clusters. Researchers suggest that these stars are the shredded remains of the last globular cluster of its kind.

The Milky Way is home to about 150 globular clusters, of which it is a million-star ball. These groups have existed thanks to the expansion of the Milky Way for billions of years. Learn more about BGR.

 

The media is in crisis and you can fix it

You’re reading this because you’re a quality, intelligent, objective journalist. Thank you for your time and confidence.

He also knows that the media is facing an unprecedented crisis. You’re also likely to hear about sudden layoffs and pay cuts in the industry. There are many reasons why the media economy is broken. But the main challenge is that the other right people still don’t pay enough for smart journalism.

We have a full newsroom of talented young journalists. We also have the most powerful data editing and verification team in the country, news photographers and video professionals. We are building the ultimate ambitious and dynamic data platform in India. And there’s not even three of us yet.

At ThePrint, we invest in quality editors. We pay them on time, even in those difficult times. As you may have noticed, we are not reluctant to spend whatever it takes to make sure our hounds get to where the story is. Our stellar coronavirus policy is a smart example.
