conclusion, the air pollution did accelerate the climate warming, then the warm climate did accelerate the glacier melting.

1’36 a mood landscape of NY was made due to the twitters that people located and show the seperation of moods.

1’38 a research about dolphins and whales that live in oceans of Hawaii, they like certain depths that are difficult for people to analyze their living condition

1’07 a brain-like tissue can be produced in order to help scientists to cure brain diseases

1’51 the tissue doesn’t act exactly like brain and is only at its beginning, but there’re lots of benefits in this work

2’19 a kind of bird can learn from their older ones to fly straight, there’re researches show that this bird tend to fly straighter when they get older

3’44 the Alpine glaciers used to contain lots of ice, scientists consider that before global warming, the pollution of Industry Revolution might be the reason of the melting ice.

2: whales in hawaii island:   

--// 18 species ,  
--// there is a blank area in what depth the whales prefer ,or where is their location range?
--// a scientific team conducting this job for unique, long-lasting ,whole 13 years and has some important findings for biology / aquacluture / naval exercise
--// e.g, about the depth ,some whales are like to  aggregate shallow area (within 500 meter) , others are active in area ranging from 500+ to more . so both groups are neighter ideal for aqua culture (since the whale will steal the fish to feed on)
     other e.g , since the location of above whales are wider than previous thought--the area is also affected by sonar emited by naval fleets as they proceed exercise.

3: human stem cell mimic human brain  

--// with adavanced tech ,realize a new level of stem cell assembly.
--// acclaimed , exalted , and somewhat unexpected.
--// has a promising path to form brain mimicry.

4 continuity of  human stem cell mimic human brain  

--// for validating the effectiveness of the mimicry of stem cell assembly, scientists have compared two stem cells' prototypies( one from illed person, the other from healthy one.)
--// the result is good for not only to confirm the old theory,but also to demostrate the bright prospect and potential of stem cell assembly.
--//prudent and careful to the robustness of the application of these attempts.

5  cran 's migration      (355w)
--// phenomenon : it is the old cranes that matter an efficient travel.
--// scientists have accumulated data(8 yrs) for substantiating the efficency of old veterans. (meanwhile ,scientists also use captive-bred <fake bird>)
--//Age and presumably experience matter more than genetics for efficient migration. --An oxford scholar take experiments to find out that youngster still learn more from olders than their normal flight mates.
--// above all, scientist initially confirm that 1) older  is very important to convey kw in migration.2) they cast doubt on whether the crane groups have lost some culture that is critical for their migration.


7: How soot killed the Little Ice Age  [677]

overview:  what factors cause the alpine glaciers melt.
whole process(in current conclusion) :  
--//a little cold period (=500yrs) from 13C'end to 19C'middle ,(=1850) ;
2--//then  black soot be scientifically confirmed of main factor (large amount : cause melt);
--//then 1910(the assumed date for melt ,according to accumulated Apline data) ;
--//finally, from 1970 ,the warming climate dominates the new-round melt.(Hypothesis: at current rate, 2099 is date for no glacier) .

2, the detailed process for scientifical exploration.
--// the rich ,apprent Apline data manifestation incur doubt and contradiction(Prof: climate records don't capture sth.)
--// he discussed with a parnter who are expert(hydrologist) on black soot.(the pair decide to investigate)
--// there is clear historical record for soot on street. But can soot float in a high level? To further answer this kind of question, they discovered the samples from the 2 peeks.In a mass balance model, the discovery give a plausible evidence for conclusion.

Researchers mapped the mood picture of New York by the data from twitter. They found that people near Central park are happier than those near transportation station and are gladder in the evening than in the morning.

Scientist used 13 year to found the specific habitat of different kinds of dophins and whales in Hawaii. Those ocean creations occupy most part of the sea.

According to the latest Nature,researcher got the brain-like tissue developed from the skin cell.In the early stage of the research, the brain-like tissue is still small and does not have same function as the real brain has. The research demostrates the theory about M and the possibility for using stem cell to simulate other disorder.
5.2:03
Researchers found that the old crane can recognize a shorter route in migration. Some Professor thinks the importance of this process is that birds in different generation would transmite the information of migration. Others think that young birds can learn from the old one and it might be the missing culture which will help the cirds in re-building the population.

Scientists use tweets of people to make a emotional landscope of New York City.(positive,negtive and neutral)

time:1:52.02
There are 18 species live in Hawaii and people are studying their habitats and these studyies are important for people to make training and facilities without bothering these species.These days the finding reveals that many species live in a huge range and there is no space that can be used by people without influence these species.

A new study found that stem cells from our skin can become resemble with our brain.Formal study can shape these cell into some organs and nero clumps,but the most advanced study shape these cell into more brain-like conditions.This finding can be helpful for people to deal with nerological disease.
____________________
time:2:09.25
The cell clumps is not like brain in shape and also lack blood vessels and have other limitations.
Though put into conditions that can help them grow like a brain,the cell clumps under microsephaly can not evolve like a brain in a healthy person.
This experiment is still in its early stage but have many significance and these cells can still be used to shape other organs or something in human bodies.

Age and experience are more important than gene or other things for this bird to migration.
The study shows that the closer the young follow the old,the more straight they head to their destination.
Whether the young learn from the old is an important study that can help people know the information transimitting between generations.

The A glacier should have grew bigger than it was at the begginning of 20 century(?),actually it started to retreat rather than grew.Explore the reason(less precipitation and recent global warming are not the reason)
Recent study found that the soot accumulating on the surfaces of ice is the reason because darker surface helped the glacier melt quicker than before.And the model also proves this idea.
The soot led to the retreat of glacier and after the air quality became better,it was the rising temprature that melt the glacier quicker.

The finding.

Time4: 1’46
An experiment indicates that stem cells may be used to research N disease.
How the experiment differs from the past ones and What the scientists did with the cells.

Scientists use a system to model a particular kind of disorder.
The limitation of the use of the system.
The finding demonstrates a previous theory and shows a possible application in the future.
