Here is the news. A team of scientists from China, Britain and Denmark has constructed a comprehensive Marine Micro -Biome database demonstrating the potential of marine micro -organisms for science research and biotechnological applications.
The research team, led by BGI Research, a Shenzhen -based life science organisation, Johnson spent five years reanalyzing nearly 240 TB of publicly available data, and built a database containing some 43 ,000 genomes and 2 .4 billion gene sequences.
More than 20 ,000 of these genomes were identified as potential novel species.
The study has been published in the journal Nature.
This database contains information on marine ecosystems ranging from the Antarctic to the Arctic, from coastal areas to the open ocean and from the ocean's surface to the 10 ,000 -meter deep, Heidel Zone.
Fan Guangyi with BGI research noted that this study provided new insights into how these microorganisms are distributed across different environments.
The research team uncovered three new enzymes for plastic degradation, one of which can degrade PET plastic film within three days, with the degradation rate of 83%.
Li Shengying, co -corresponding author of the study, said that one gram of this enzyme can degrade 55 plastic water bottles of 500 millimetres each.
Li highlighted that this advancement would play a positive role in addressing plastic pollution, particularly in achieving green, low carbon, and sustainable use of PET plastics in China." Li added that the enzymes will also help reduce the reliance of the plastic manufacturing industry on petroleum and lower its carbon emissions.
In this study the research team also explored the database's genetic resources from multiple dimensions identifying 36 new gene editing systems.
Researchers investigated the application potential of one of these systems, which has proven highly effective for genome editing in all testing scenarios.
This highlights its potential as a new tool for basic research and translational medicine development.
Building on these results, BGI Research has partnered with the Hong Kong Polytechnic University to establish a joint research center for further development and commercialization.

Chinese researchers, in collaboration with counterparts from France, Germany and Ireland, have made joint efforts to reveal the deceleration pattern of the Earth's rotation.
They discovered that between 650 million and 280 million years ago, the Earth -Moon distance increased by approximately 20 ,000 kilometers, and the length of a day extended by roughly 2 .2 hours.
The Earth's rotation has been slowing over time due to tidal dissipation, but the rate of this deceleration has not been consistently established.
The researchers analyzed eight geological data sets to reconstruct the Earth's rotational history from 650 million to 240 million years ago, identifying a staircase pattern in the Earth's deceleration between 650 million and 280 million years ago.
According to the article published in the journal, Proceedings of the National Academy of Sciences, specifically, there are two periods with high earth rotation deceleration, namely from 650 to 500 million years ago, and from 350 to 280 million years ago, separated by an interval of stalled deceleration from 500 million to 350 million years ago.
The article noted that these two periods roughly coincided with the Cambrian Explosion and the largest mass extinction event in Earth's history, adding that the two periods may have provided the necessary conditions for the evolution of early marine ecosystems.
Ma Chao, a professor at the Chengdu University of Technology, said that the study has important theoretical significance for exploring the climate, environment, and biological evolution during the Earth's rotation deceleration period.
According to Ma, the team of researchers will further study the internal links between the Earth's rotation changes and natural phenomena, such as the Earth's magnetic field, tidal actions and climate change in order to build a more comprehensive and accurate earth -system evolution model.

An ancient rock painting site has been discovered in the Tong Tian River basin in the source area of the Yangtze River in northwest China's Qinghai province.
According to local authorities, the site is located on a cliff at an altitude of 4 ,094 meters in Yushu, featuring nomadic rock styles of life on the grasslands in northern China.
The new discovery will provide important evidence for studying the culture at the source of the Yangtze River.
So far over sixty sites of nearly 10 ,000 rock paintings have been discovered in the Tongtien River Basin, with the earliest dating back some 3 ,200 years.
The rock paintings are rich in images.
In addition to human figures, there are animal images such as jacks, deer, wolves, as well as images of two -wheeled vehicles, among other symbols.
A nature reserve in northeast China's Liaoning Province has recorded 11 ,175 raptors in a day during its Autumn Raptor Monitoring.
The number, a record high, marks the first time on the Chinese mainland that over 10 ,000 raptors have been recorded in a single day during autumn monitoring.
Located in Da Lian, the Snake Island, Laotiei Mountain, National Nature Reserve, is an important node on the East Asian Australasian Flyway, with raptors being the most common species among migratory birds in the area.
Wang Xiaoping, Deputy Director of the Reserve's Administration, said that monitoring the changes in raptor populations is crucial for assessing the ecological health of the region.
One noted that the reserve began raptor monitoring in 2018 and they recorded a total of 85 ,567 raptors last autumn.
The Snake Island Laotie Mountain Biosphere Reserve as a site of migratory birds along the coast of the Yellow Sea, Borghai Gulf of China, was inscribed on the World Heritage List by UNESCO this July.
This is Special English What day is the most auspicious one in a year?
If you can choose from several lucky numbers in Chinese tradition and make a combination, what will be your guess?
Let's say eight, eight, six, nine, or one—August 8, June 9, September 8, or January 6.
Wait, wait—that's the wrong direction.
According to the ancient Book of Changes, numbers from one to ten have have either yin or yang characteristics.
Odd numbers, such as 1, 3, 5, are yang numbers, while even numbers like 2, 4, 6 are yin numbers.
In this case, the number 9 is the biggest number, which means growth, prosperity, longevity, and all the good stuff in life.
So the most auspicious day of a year in Chinese culture must be the Double Ninth Festival, also known as the Chongyang Festival.
It falls on the ninth day of the ninth month, according to it falls on October 11th this year.
Well, with the number repeated twice in a row, double -ninth means that all those good things in life, such as one's years, luck, blessings, and happiness, will last twice as long.
You can tell how auspicious the double -ninth can be.
Is there any other day that can be better than this day?
I'm afraid not. Well, how would Chinese people celebrate the double -ninth festival?
First, climbing hills.
You don't have to be as professional as a free soloist to climb mountains.
In fact, since ancient times, people have been practicing this without strict rules.
They do this for an auspicious reason.
The higher you climb, the better life quality you'll get.
How much I wish this were true.
Eating Chongyuan Cakes.
In China, each festival offers a special opportunity for people to enjoy food matched with the festivity or the season.
As you may know, mooncakes for the moon festival and sweet green rice bowl for the Ching Ming Day, stuff like that.
just like what roast Turkey means at Christmas.
So for the most auspicious day of the year, food that's tailor -made for the double -ninth festival must be something special.
That's right, it's the cheong yang cake, or by another name, flour cake.
its round in shape, made from rice, scattered with dried fruit, roasted nuts and dyed in different colors.
It usually looks like an excel pie chart, with five chairs.
Another tradition is to appreciate chrysanthemums.
In late autumn, when the weather gets cold, little flowers are vital enough to blossom fully.
However, chrysanthemum flowers are not afraid of the harsh weather and blossom without hesitation.
They never stand out with fragrance, but proudly fight against the cold.
world. With artificial cultivation, chrysanthemums bloom in various shapes and colours.
They symbolise fidelity, optimism, joy and long life, of course.
And these have been recorded in some well -known Chinese poems.
Those who do not know anything about the chrysanthemums' presence in Chinese poetry, cannot boast of any skillfulness in Chinese culture.
Yes, that's true. And the final one is wearing cornells or dogwood.
It is said that since the Han Dynasty, people began to pray for longevity during the Chongyang Festival.
It was a result of the influence of the Taoist pursuit of eternal life.
faith. People take some herbal medicines for this purpose, or wear corn owls, little red fruit, in the hope of driving away evil.
However, as time goes by, one can no longer see anyone wearing corn owls on the double -ninth day.
Now things do change with the times.
Since the late 1980s, the double -ninth festival was named as Senior Citizens' Day in China, giving this day greater significance.
It focuses on the Chinese traditional virtues of honouring, respecting, loving, and helping the elderly.
Senior people will be invited to dine in fancy restaurants.
Go shopping, watch a film, go to a spa, or enjoy theatrical performances.
And finally, let's enjoy a famous Chinese poem about the Double Ninth Festival, entitled Thinking About My Brothers in Shandong on the Double Ninth Day.
Only all alone in a foreign land.
I am twice as homesick on this day, when brothers carry dogwood up the mountain.
Each of them a branch and my branch missing.

the essence of life itself.
From the stem of trees to the gurgle of rivers.
From the silent strength of mountains to the icy whispers of glaciers.
