Imagine the desert, the non -hospitable landscapes of the endless sand dunes and the arid rocks come to mind.
This is largely the case today, but 7000 years ago the vast desert was a completely different place: a green world of trees, rivers and homeland for Megavaina like river and elephant mares.
Over the past decades, scientists have details the “Green Desert”. Now, with the help of the old DNA of stuffed residue, genetic scientists discover those who lived there.
A long time ago
The residues of a woman who are buried in the Takarkori Rock shelter dates back to about 7000 years. – The archaeological mission at the University of Desert/Sabinza in Rome
Takarkori Rock – located in the Tadrtrart Acacus in southwestern Libya – offers a great glimpse in the most green in the desert.
Archaeologists revealed the remains of 15 women and children on the site two decades ago.
Initial attempts to extract the old DNA from the remains fell flat. Cold and continuous conditions – the opposite of maximum temperature fluctuations in the desert today – results in the best preserved DNA.
The new technologies have made the genome sequence – a full range of genetic materials – for a mummified woman. Analysis Exciting information about the original revealed From the people of Takarkori and how they adopted a lifestyle of grazing.

Dark Energy is a mysterious power that accelerates the expansion of the universe, and it is believed to represent about 70 % of the energy in the universe.
New evidence of the cooperation of the spectral tools for dark energy, known as Desi Dark energy may act in unexpected ways Perhaps the weakness is over time.
In its fourth year of wiping the sky, cooperation now released the latest collection of data. Although it is not the last word, information is enthusiastic about space scientists.
“We are in the field of allowing the universe to tell us how it works, and the universe may tell us that it is more complicated than we thought it was,” said André Koso, a post -PhD researcher at the Lawrence Berkeley National Laboratory, who runs Disi.

The Spacex Falcon 9 missiles sent four tourists in the crew of the crew capsule He has not tried a polar orbit before.
The leadership of the Fram2 mission was Chun Wang, who made his wealth run Bitcoin mining. Spacex has paid an amount that has not been disclosed for this trip.
Watch a video of Spacecraft’s Splashdown Film Coast on Friday after Wang and his colleagues-cinematic director Janek Mickelsen, and robotics researcher Rabia Rouge and the adventurer Eric Philips -3.5 days in the low Earth orbit.
This was the first journey to the space for each of the four crew members, who have all relationships with polar land exploration.
Meanwhile, Sony Williams Watch Watch from NASA this week spoke for the first time after a lengthy mission for nine months to space. This is what they said.

For non -trained eye, stone tools may look like regular rocks, but for specialists they have great stories they tell.
The researchers found stone artifacts made in a manner closely linked to Anander in East Asia for the first time at a location in the southern West Chinese province of Yunnan.
This discovery, dating back 60,000 to 50,000 years, has puzzled archaeologists, who have reached competing hypotheses to explain stone tools.
Perhaps it was possible that the primitive human beings migrated and reached what is now China, or A different type of ancient human tools may have been made An abrogated similar to those who were discovered in Europe.
Either way, the answer can shake what is known about human origins during the Stone Age.

The head author of the study, Plackley, said that he was among a small group that recognized three initial feet at the distant location on the Trotternish Peninsula in 2019 when he was a graduate student at Edinburgh University.
“It was very exciting,” said Blackley. Documenting a total of 131 effects, used a drone to take thousands of overlapping pictures of the site before producing digital 3D models for paths. He added that she was preserved in “wonderful details”.
