1. 0'53'' glaciers have a hole in protecting mountaintops, now even mid-latitude areas like Mont Blanc.

2. 0'59'' evidence demonstrates that far less effecive erosion takes place in glacier-covered areas. Still limits: not all mountains, and rising temperation.

3. 1'39'' transplant human cells to mice to complete developmental process, which involves 3D tech.

4. 0'56'' exciting study: restore diseased organ. challenge: lack of automated cell proliferation.

5. 1'16'' clouds of growing moisture observed in polar regions is explained by the increasing numbers of rocket launches.

6. 4'02'' shark bites: 1) self-alarm 3what 2) community protection actions 3) community response to after-shark-attack events.

1:47
Mont Blanc is protected by its glaciers from erosion.
1:48
A study shows that Mont Blanc is protected by its glaciers. However, not all glaciers can protect the erosion of the mountain.
2:39
The Japanese are trying to grow a liver and use it to replace the sick one.
1:30
The meaning of the study and how long it can be applied to human
1:58
The clouds formed in the space may be a result of rocket lauches.
6:45
main idea: How to deal with shark attacks
structure:
-the suggestions to the bathers
-what the communities can do to prevent shark attacks and balance the costs with fear

谢谢ppx~ 这次的越障不太难也挺有意思的~

Mont Blanc is protected by the glacier. This fact is opposite against the scientist knowledge which think the glacier reduce the moutain height.

02:50
the study team researched the reason why the glacier protects the Mont Blanc. the researcher thinks that as the global warming is coming, the ice melt will erosion the mountain.

03:30

Japanese scientist researched that the humane liver cells can be transplant into mice and grow a real liver whose function is same with the humane liver.

02:10
Austrilian scientist thinks that the application of this technic will meet some difficulities.
Because if the doctor injected the precursor cell into humane, the doctor can not produce the automated cell proliferation, this funtion will implement at least decade later.

3:30
The article introduce that the water increase at the high altitudes over the polar regions. The
reason is the increase of the launch of the rocket.

9:49

The author introduces several methods to avoid shark.
The first one is weather. never go to sea in 24 hours after storm
the second one is distance. never swin far away from the shore and swin alone.
Twons near cape cod should advertise or radio the risk of the shark near the shore.

how the public and governments respond to shark bites
//be dangerous and a healthy respect
"What's the weather?"
   "What's the time of day and the environmental conditions?"
"What am I doing?"
//conveying information to the public
encourage people to swim close to shore.
information on the weather and shark behavior can help.

Time1
1'23''
The glaciers help Mont Blanc gain height and protect the mountain from erosion.
Time2
1'22''
The experiment demonstrates that the role of glaciers is affected by temperatures.
Time3
2'12''
The Japanese scientists wanted to transplant the precursor cells into humans and let them develop into replacements for diseased or damaged organs. They did liver experiments in the mice and found that liver buds could engraft to the mice.
Time4
1'26''
Otherwise the experiment shows some merits but there are signifiant hurdles to clear before the technique reaches the clinic.
Time5
1'56''
An unexpected increase in the water content of certain thin, wispy clouds at high altitudes over polar regins in 2011 and 2012 may be the result of more rocket launches.
Obstacle
6'51''
Neff spoke to National Geographic about how communities and individues should do to deal with shark attack.
1. What should individues do?
2. What should communities do?
3. How does people response to shark bites changed over the years? What kind of action    should a community do after shark bites?

SPEED
1 1'27 glaciers prevent mont blanc from erosion
2 1'20 the study about the finding above and the adds
3 2'41 an introduction of the experiment about transplant human's liver stem cells into mice
4 1'23
[proliferation]增殖
the experiment shows the precursor cells could be applied to organs but it still need long time to practice  
5 2'20 the rockets launches cause the moister and more frequent clouds  at high altitudes in recent 3 years
OBSTACLE
6’00
some suggestion that swimmers could avoid being attacked and government adopts to protect swimmers

1. 02:25  Scientists have discovered that the glacier have been working as a 'shield', protecting the low to high latitude mountaintops from erosion.

2. 02:33  The research team has discovered that the erosion is 16 times less effective in the coldest glacier area compare to the warmer area. But another Yale professor points out that the glacier does not guarantee to protect the mountain, glaciers with a wet base are very erosive.

3. 02:34  The sciencists in Japan has generated the functional human organ cells in lab then transplant it into human body, allowing it to grow into organ. This process will eliminated the complete transplant which rejected by the human immune system. Sciencists have tried to transplant the cells into mice and it works well so far.

4. However there is a limitation to this. In order to transplant the live buds into human body and let it grow into a complete organ, huge amount of cell buds are required. In order to get that much of cell buds a breakthrough in automated cell proliferation is reqiured. And this technology will not be available for at least a decade away.
