Eariler study shows that fetuses can hear sound.But more recent study shows that fetuses actually can learn words and this learning capability is more specific than people thought before.

An experiment.Fetuses lisetend to the word"tatata" before they were born.And scientists found that these babies have special reaction when they hear "tatata"agian.This fact proves that fetuses can hear and remember words.
This found can have positive effect to help fetuses who have disability in learniing a language.

Scientists found a star named HIP...that is like the sun's twin and can show evolution process of the sun.
For example,L is an elment that is found in other stars but is absent in Sun and HIP...This fact can show that a star may burn through L when it ages.These kind of finding can help people learn more about the inner working of a star.

The research help people to discovery unknow planets but this is a tough work.
It is difficlut to find a twin of sun.And HIP...is an ideal choice becuase it resembles sun in many aspects.It is also the oldest one that has been ever found.
The evolution process of HIP can help us exam the process of the sun.

A new research found that three percent of ... is co-orbital and this pecentage is much higher than people thought.
By studying the asteroid T,which is temporarily captured,people can knew the evolution of solar system.

An experiment that firstly simulate the whole process of the evolution of the early universe.
The basis is echos of the big bang.That means scientist used the similar historical events that resulted from the big bang as the basic material of the experiment.
The subject of the experiment is ultalcold atom.Studying how these atoms move under certain conditions can simulate how the early universe evolved.
There is a phenomenon named S acoustic O that can expalin the movement and fluctuation of the atoms.
These atoms moved during the evolution of the early universe.And the comlexity is the reason of the formation of the big bang...
This analogy:1 the experiment is very small,but the finding can appy to the big universe
2 the experiment can complete the evolution in a ...seconds,but the universe spent ..million..years
The ultralcold atoms can also be used to simulate other model,such as the formation of cloud..black holes..etc..The prospective and improvement of this experiment. |
