The scientists know that liver cell could regenerate itself if part of it is removed.
Bhatia and colleagues have taken a step toward.They have identified a dozen chemical compounds that can help liver cells not only maintain their normal function while grown in a lab dish,but also multiply to produce new tissue.
Face two big challenges:
1.study how 12500 different chemicals affect liver-cell growth and function.
2.get the recipient's body to grow blood vessels to supply the new tissue with oxygen and nutrients.
Bhatia and colleagues solve them well.

2:28 Studies show that genetic factors associated with social factors can contribute to one's schooling. Other not-yet-identified factors can have impact as well.
1:41 Experiments show that gene isn't strongly connected with education level. Other factors can affect edu lvl, so it's hard to determine what really matters.
1:24 Researchers didn't really find gene to be correlated with edu. The experiments could be mistaken since the relation between gene and edu is so tiny that it could just be a coincidence.
1:52 The newly developped rover could reduce the radiation exposure to 2/3 of that of previous exposure when astronouts travel to Mars. New measurement of radiation could provide some more reliable prediction of radiation exposure.
1:59 Magnetic monopoles are measured through magnetic whirls, the whirls could one day contribute to the production of computer components. The significance of S formed in previous years. And researchers tested to see what consequence could result if whirls are distroyed.

4:12 Liver could regrow if part of it is lost. Researchers are exploring ways to regrow liver. 2 ways are presented: through large-scale screening and make connections, and the latter makes progress compared with the former.

scientists have found that gene may have influence on the schooling and social ability of human.
2.2'08'': 322 words
scientists have dilivered experiment research on the conclusion above and the experiment approve the conclusion. But some critics claimed that we did not know what the scientists had measured.
3.1'39'': 238 words
many researchers from different school claimed that the the tiny single is pointless but it can be misinterpreted.
4.2'30'': 328 words
exposuring in on the Mars makes astronauts suffer a great danger of health.
5.2'25'': 340 words
scientist has made an artificial monopole to see whether there is monopole in the world
6.5'34'': 911 words
structure:
1) introduce the topic: scientists have find ways to make artificial liver survive and reproduce outside the body.
2) the first milestone: liver can be reproduced by themselves outside the body
3) the second milestone: the artificial liver works well after transplantation

The recent study indicates that the genetic factors correlate with the education achievement: however, these factors can only explain a little discrepency of educated level, which some social or presonality traits impact more effectively.

2:32
According to the data collected by Curiosity, the dose of radiation a astronaut is exposed to are considerable potential for health risk.

2:40
The scientists discover a new type of artificial monopole that has lots of theory and application potential.

6:23
Two compounds prove to be vital to the maturation and functioning of liver, promising a bright future of tissue engineering.
