[2:21]Because of climate change, pollar bears now have little time to hunt seals. They turn to eat eggs of birds. Therefore, the climate change not only have an effect on bears but also have an effect on other animals.

[2:01]To figure out how corns develop from teosintes. researchers simulate the growing condition in the greenhouse to grow teosintes. The result turns out that in this condition corns are easier to be mature.

[2:48]Two moneys born in China that have been edit genes. This provide hope to scientists that a new type of fene therapy may oneday will help human to correct genetic defects.
[3:32]->To disrupt genes, scientists target three kinds of genes.  The first two monkeys that have been disrupted two kinds of genes have been born. Scientists are still waiting for the other two kinds of disrupted genes.
->It turns out that only targeted genes have been disrupted.
->There are also some problems. First, the techique is not as efficient as the researchers had hoped. Second, the enayme didn't start to snipp until they divide, lving some genes unaltered. therefore scientists don't know the result until these monkeys produce offsprings.

[1:48]J&J partnered with Yale University to make some of its raw material of its clinical trials data available to others. Yale University set up an organization that will decide who can use the data.

2,338 2‘15 ice vanishing-> seals to eat for bears -> bears eat bird eggs
3,176 1'07 researchers simulate the process teosinte turn to corn to find how it happen
4,319 2'03 edit DNA->hope for curve diseases come from gene
5,363 1'35 which gene to edit;long way to watch with some problems
6,281 1'44 researching in raw data of drug->include other thing;maybe it is illegal

1.speaker: Rosetta has experienced a hibernation, which brought the scientists a long tough time.
2.2'24 Polar bears do not have enough time and energy to hunt seals when the ice breaks up early through the ice-free season.
3. 0'50 the way the teosinte be domesticated into corn.
4. 1'52 the researches on two editted-gene monkeys. Scientist from different universities found several ways that gene transfer information by.
5. 2'14 scientists made an experiment to find out how genes are transferred from one cell to another. But there are something they can not do because of the limit of technology. And they still need to wait for years to see the results of their study.
6. 1'42 JJ will share its raw data from its clinical trials. And the YODA will review these data.
7.4'53 scientists have found some evidence to explain the exist of Jehol fossils. First, the author introduces the Jehol fossils. Then, he presents the way scientists solve  the mystery. At last, he review the results of previous studies.

Polar bears eat seabird eggs due to climate change.When they face 2 months of ice-free habits, and can not prey on ring seals. These thing effects both polar bears and seabirds.

Corn’s ancestor is called teosinte,grew in greenhouse.

After Hibernation, Rosetta Seeks Its Stone
Rosetta is going back to business, it used to hibernate in June 2011, its operating is just fine, many people cheering. Why? The space craft gets its power from solar

Speed
Hungry Polar Bears Turn to Seabird Eggs
Time2: 2'16" Without seals to eat, the bears have increasingly turned to terrestrial prey, including the eggs of northern common eiders and thick-billed murres

What Did Corn's Ancestor Really Look Like?
Time3: 1'14" How did an ugly grass become one of the world’s most important crops? The answer is that ancient teosinte grew differently from its modern counterpart

Monkeys born with edited genes
Time4: 2'04" A Chinese team successes in creating edited gene monkeys by injecting mRNA used to produce Cas9
Time5: 3'36" CRISPRs could be used to repair some human genes without inadvertently damaging others.

Drug Company Teaming with Yale to Share Trial Data
Time6: 1'42" Johnson & Johnson announced an unusual partnership today with Yale University, in which it will share raw data from many of its clinical trials

Scientists Solve Mystery of "Chinese Pompeii"

Time7: 7'37"
the material that entombed the animals also killed them, overwhelming them in a hot cloud of ash
Although it’s possible that flying birds could have been overcome by poisonous volcanic gases and fallen directly into the ancient lakes, that doesn’t explain how the other nonaquatic animals got there
The comparison between Jehol fossils and Pompeii

an ancient lake in china reveals some intresting discovery: fossoils of many different animals. professor use two ways to find the truth, microsell and muscule both give proofs. the accident might happen as a whole , so animals coud be preserved in good condition. the same dizaster in rome remind the tep is low and slow.
