Tens of thousands of years ago, our gender – the sane person – mixed with other people in prehistoric: our distant cousins, primitive human beings and Densovan.
favorable Primitive excavations Give us a good idea of their appearance, lives and relationships, but it is not much known about Denisovan that they still do not have an official scientific name.
Evidence of its presence appeared in faded effects, which was appointed by the signs of the DNA that lie in our genetic composition and confirm only some fossil fragments.
This week, however, a 146,000 -year -old skull was bulldozed from a well in China in 2018 may be just a major piece of this hidden evolutionary puzzle.
A long time ago

The full skull did not match almost any previously known types of prehistoric human.
But two new studies – what researchers say are among the largest papers of this year – show in detail how scientists were able to extract genetic materials from fossil and help detect this biological ambiguity.
the DNA sample is taken from “Dragon Man”, As the sample is called, it revealed that it was actually linked to Denisovan, the first human beings who are believed to have lived between 500,000 and 30,000 years.
This result can be huge, which helps to draw a complete image of the time in which our own type lives with other people in prehistoric.
Through the universe
Astronomers have long struggled with the dilemma of the “dark matter”, but many puzzles surround regular materials as well.
The proton -based atoms are called the Parronic material. This substance is scattered between galaxies like fog between galaxies, which makes it very difficult to measure it.
Perhaps, this, so far.
A new study explains how scientists managed to monitor the Barruni issue using Fastage of rapid radio bursts.

Fruits, flowers, birds and musical instruments decorated the walls of a luxury villa – part of a site called the excavation team called “Beverly Hills” in Romanian Britain – before the building was demolished nearly 1800 years ago.
the The wall panels were collected hard -harded together By experts from the London Antiquities Museum. Han Lee, a great building material in Moula, described the effort as a “once age” chance.
The Romans invaded Britain in the modern era in 43 meters and created Lunddenem, the modern London introduction. The occupation continued for nearly 400 years.

Scientists say that marine spiders in Serkosura may pass the bacteria that methane fed to hatching as an easy source of food. – Shanna Jofridi
In light of the lavish sunflower, methane is a dangerous gas that must be avoided.
A chemical pollution that carries heat in the Earth’s atmosphere, methane increases the climate crisis. But within the deep rest periods of the planet – thousands of feet below the surface of the ocean off the American West Coast – the gas can be converted into a nourishing meal.
At least for spiders.
Scientists say they have discovered three types unknown by the sea spider that live around methane leaks. In these maritime habitats where sunlight cannot reach, gas escapes through cracks at the sea floor and feed The bacteria that hold the outer structure of the spiders.
Carbon -rich methane and oxygen are transformed into sugars and fats that spiders can eat, according to a new study.
Researchers suggest that the newly discovered water spiders may pass the bacteria that methane will be screaming as an easy source of food.
