Time2-1'46"

stone, Egypt desert, struck Earth, turn sand to glass, evidence of atmosphere.

Time3-1'56"

Syrian scientists applied to IEE's SRF. Much more applications than before.

(forget)

Syria, dictatorship. Few improvement, thanks to young scholars.

Students support uprising, but professors don't because of bad experience that opponents disappeared before.

Time4-3'02"

Condemn and be arrest by government. Professor JT is arrested and tortured by government.

Leave Syria in Aug 2011, and with SRF since Jun 2012.

Professors are arrested or killed by government because of their political opinions and other reasons.

Some Professors are arrested or killed by rebels, but much less than those by regime.

Time5-3'25"

Regime destroy labs, and education system in unviersity is collapsed.

Some students go aboard, but without documents, they can't study aborad. Some countries give some help.

Some research continue aborad. Because of lack of materials, research in Syria is stopped.

Other countries should help scholars and refugees.

Need to rebuild eduation system.

Time6-4'53"

Female mosquito, fossil, blood.

Evidence, ancent insect, stuck blood.

Molecules in blood, can't find in male mosquito.

Preserve well in mediums other than amble. Blood keep long.

Obstacle-11'22"

Find some moleculars keep a healthy brain.

FNDC5 heal diseases.

PGC-1a don't find in mice brain. But bot FNDC5 and PGC-1a find in human brain.

S find FNDC5 cause BDNF in brain. The link is accepted but mechanism still unknown.

S set a experiment, keep some mice running.

Runners have more FNDC5 in brain.

More PGC-1a cause more FNDC5 cause more BDNF.

S make some assumptions and do experiment. Inject virus and get some results.

Results explains where brain's BDNF come from.

But results doesn't answer question.

Scientists will focus on irisin, development of FNDC5 to keep a healthy brain.

Speaker: The speaker makes a point that the more we see the photo of foods, the less they are appealing to us, and mentions the possible reason.
Time2  2:00 The ancient comet explosion and the reaction, scientific findings.
Time 3   1:16 The social unrest in Syria makes brilliant scientists flee out of their home country.
Time 4   1:14 The scholars in Syria find their lives at stake in their country for several reasons,as a result, they have to go abroad.
Time 5   1:08 The research are highly affected by the war, Syria scholars are eager to find their solutions.
Time 6   2:10 The feeding habit of mosquito can be dated back a long time ago, this new finding shows that the remains of blood can be traced if in the right condition, and the remains of mosquito can be preserved in other medium.
Obstacle  4:58 Researchers find link between a work out and a healthy brain. This process is achieved by two important factors FNDC5 and BNDF.

[1:41] A place that was thought to be an evidence of meteor struking the earth was proved to be the comet.
[1:31] An organization that helps scientists to get away from the firghten of war. A scientist from Syria talks about the complexion in Syria.
[1:44] Schlors are targeted in Syria. Even the female professor from Syria was warned. Regime hates profeesors for many reasons. Some rebels are also against professors, but the number is seldom.
[1:58] Education in Syria collapsed. Students and professors are forced out of universities and some of them fled. But students don't have document so they cannot study abroad. Some countries offer help to them. The scientist hopes that other countries can offer help. Even the country will rebuild. It has a lost generation and lack of intelligent minds.
[1:52] Scientists find that a blood-filled mosquito and its influence.
[7:38] How scientists find that exerise has a relationship with the brain. He tested that when people do exercise, their muscle secrete FNDC5. Accicidently, he found the brain secrete FNDC5 too.
To testify the finding. They used mice and trains mice to do lifting. But they don't have FNDC5 instead they have PGC. Pgc will boost the decrert of FNDC5.
They also find how brain gets signal to release FNDC5. But there remains problems that some other organs in people will also help to decrete FNDC5

thank you PPX!
1 speaker people who see the photos of foods with similar tastes will feel less appealed to eat the food
2 2'21 the process of identify and prove the first evidence of comet exploding to earth
3 2'19 the Syria academic atmosphere is suffering in wartime ---infrastructure, freedom of speech, students' access to education
4 3'09 the way to help and the results of no action.
5 2'47 the discovery and research of a fossil of a blood-filled mosquito
obstacle:
6 7'42 the connection between excersice and brain function of learning and memory and significance of this discorvery

Main idea:
Excising can help to improve brain neuro
Author attitidue:
Positive
Structure:
-Scientist can't explain why exercising can help brain neuro
-
Spiegelman and his colleagues find this out, and do experiments on mice to test their assumption
-
Spiegelman explain how exercising works on brain.

Time2 1min40 comet first struck the earth and the scientists research the origin of comet through a range of tests.
Time3 1min20 the exodus of scientists out of syria and the sscientists had a bad experience there.
Time4 1min 15 the sicentists in syria live in danger and don’t have a free speech who often targeted by the government.
Time5 the lab and education sytstmen were collapsed by the war ,in addtion, many students living syria without documents who can’t  continue to study , the faculty wer taken as enimies, so the regime will fall sooner or later.]
Time6  a fossial of blood-feeding masquito was first founded in shale sendiments and molecules in blood can be preserved for long time.
Time7   exercises can produce useful molecules to benefit our brain healthy. It mainly researches FNDC5 molecule to promote new neurons and maintain healthy neurons and then fight againts  mental  diseases. In addition, the scientists do series experiments to research the mechnism.because the FNDC5 promote the increasing of BDNF protain and the benefits of Irisin.

The pebble may be the remainder of a comet struking the Earth many years ago.
Treditional hypothesis:a meteorite impact or an airburst
New evidences(two points)indicate that the pebble in the remianer of a comet.
__________
time:1:26.12
Many schoolers and scienctists left(flet) from Syria to other countries.

How's the speaker's lab and researchs in Syria---destoried.

Syria needs help from universities in other contries.Intellectual power is essential to the rebulid of Syria.
__________
time:2:23.16
A special fossil shows that blood-sucking mosquitos exsited more than 40 million years ago.
Old view:blood-borne parasites in the body
New view:the organism fed on blood
The significance:may solve the controversial hypothesis that the blood trace are found in dinasours'fossils.
_____________
time:5:51.49
Scientists found the details of why exercises can help improve the health of brain.
Exercise--F(i)--B--brain mental health(B--brain,this relationship is found a decade ago.the formal relationships are found these days)
Experiment:two groups of mice:lift weights/don't lift weights
Question:the inside and outside factors that lead to the health of brain
Finding:i inside and outside the brain can have the same function--raise B
Oppinions:exciting,intersting,but not solve the fundemental question:how much of the outside-brain i and how much of the inside-brain i contribute to the change of B and lead to the health condition of brain?
Significance of the finding:may lead to better treatment of mental diseases and help brain become more healthy
