a new study about DNA showed some unecpected findings and the study will be published later.

noncoding DNA is DNA that doesn't code for any proteins and puzzles scientists over why they are
existing.A,H-E and other scientists found that organisms may not bulk up on genetic junk for reasons of benefit.

a new plant indicates that it is not crucial for complex life to have a bunch of noncoding.
this plant has the comparable number of genes that other like grape and tomato have.
these facts show that at three times in the course of its evolution the bladderwort's genome doubled
in size

researchers recently studied the rocks from earth and lunar and found that water inside the moon'mantle
came from meteorites and the water had the same source as that from earth.this result shows that
the water has been there all along.And to find the source of the water,scientists took a lot of efforts.

researchers measured the amount of d in the samples.
S and his colleagues found the melt inclusions have a low ratio of d/h,which shows the source of the water
on the Moon is primitive meteorites, not comets as some scientists thought.
a recent study has found that a common source for water on Earth and water on Moon.
while this finding doesn't mean it fits the earlier idea.the researchers are still working on
it.

1.people can't stack stars in a jar like marbles and take a closer look.
2.a breakthrough of imaging of exoplanets comes recently
3.researchers began to install infrared cameras and other strategies.
4.the new study found a large star orbited by at least 4 known giant.
5.while the images were not enough to reveal any information about the planets'chemical composition.
6.the results showed that the 4 planets have fifferent compositions.
7.researchers are still trying their best to get better spectra of exoplanets. |
