Fossils in China expand the human family tree

The history of human evolution is long and complex - and it becomes more complicated every year. Discoveries of the past two decades have added new branches in human family tree, including species such as the hobbitious homo floresiensis and the powerfully built Homo naledi . In 2010, a small finger bone from the Denisova Cave was discovered in the Altai mountains in Siberia, which led to the acceptance of an independent old human population, which is referred to as Denisovans and with which some people could be related today. Researchers are now trying to solve the riddle of a collection of human -like fossils that have remained unexplained for decades.

a new discovery in the human family tree

Skull residues, teeth and pine found in various places in China have triggered some researchers that they discovered the remains of a previously unknown old human relative. The scientists suggest calling this type of homo juluensis, since they have a

The secret of the fast radio eruptions

Since the discovery of mysterious fast radio eruptions in 2007, astronomers have been trying to find out what causes them. These flashes release more energy in milliseconds than the sun on a whole day. Thanks to the Canadian Hydrogen Intensity Mapping Experiment Radiotelescopes, researchers have now been able to determine the sources of two recently described outbreaks. The scientists were able to see one of these outbreaks on the turbulent and magnetically active region around a Rapidly rotating stern . The other pulse came from the outskirts of a distant, old and dead galaxy, which no longer produces new stars, according to a new study. These very different origins make astronomers assume that the flashes can occur in different environments, which could help to decrypt the phenomenon.

The survival in the wild kingdom

The brush rat tail could be confused with a miniature kangaroo due to its appearance and bag in which it wears its boy. But the small bag animal has a less cute side: the baby, which is referred to as Joey, will emit and bump away when it is threatened by robbers. This brutal strategy is necessary for the survival of a species that has experienced a decline in its population by 90 % and at times even disappeared from the Yorke Peninsula in South Australia. Nature conservation efforts bring the brush rat cock back to its ancestral country, where it plays an important ecological role. While the beams are digging according to their main food, underground mushrooms, they ventilate the ground and promote the growth of plants that other animals depend on.

look into the sky

A ring doorbell camera captured the moment when a meteor hit the sidewalk of a house on the Canadian Prince Edward Island-where the local professor Joe Velaidum had only stood a few moments earlier. Scientists have now confirmed that the specimen, which bears the name Charlottetown after the nearby capital, is actually a space rock that fell into earth in July. While videos of meteorite impacts have already been documented, this is the first time that a . The space rock probably spent millions of years from our solar system before it ended up in its new home, the Meteorite collection of the University of Alberta.

scientists used instruments of spatial probes that circle the Mars to concentrate on mysterious hills on the surface of the red planet. The deep countries of Mars cover thousands of hills and they could be the key to understanding the past of the Red Planet. These high -towering features are similar to the buttes and mesas of the Monument Valley on the border between Arizona and Utah. Ancient water flows that existed 4 to 3.8 billion years ago have probably eroded and shaped the formations, as a new analysis of orbital images shows. The hills contain that can show the history of water on Mars and which may be shown by the exomars Rosalind Franklin Rover of European Space organization that is planned for 2028 will be examined.

• melted metals inside the earth produce a constantly moving magnetic field, which means that the magnetic North Pole is not firm. He is now closer to Siberia than five years ago-and continues to drift towards Russia .
• camera snapshots helped to discover rare species, including the sun bear and the first documented viewing in Cambodia of a threatened deer type, the Großweihte muntjac , in an almost unexplored part of the Southeast Asian country.
• archaeologists in Denmark released hundreds of windows with carvings from the sun. The researchers believe that Stone Age farmers as response to a devastating volcano eruption almost 5,000 years ago.
