Time 1 2'28''
Dog may seem to be more intellgient to learn from human beings but they lose the social ablity to corperate with other dogs whereas wolves apparently do better.

Time 2 2'00''
the scientist made a experiment by first teaching 2 dogs to open the food treat in a box by lever and the other by paws. Then in a pack of mixed doges and wolfes they found intersestedly that far more wolves than dogs finally opened the box by using the methods they've been showed. the observation may indicate that dog has lost much of their learning ablity in the evolution but it can also explained as dog now only focuses on what human being does.

Time 3 4'11''
A new drug is invented to be effective in the medication of cancer.it is proved to be of good effect first in some small tumors, and it has a good chance to treat lung, kidney and stomach cancer after further advancement.but the cost of the durg is very high, so before it can provide the benefits to the mass, the
price needs to get much lower.  

Time 4 2'52''
Next generation therapy is a compounded medication of immune therapy and radiation therapy. the benefits of the new therapy is that more cancers will response to it but the price will go even higher.

Time 5 2'00''
scientist found that a group of plants with hundreds years of age reproduced after the melt of glacier.

Time 6 15'00''
3D printing technology will advance the medical treatment and in this case bioengeering scientist made a windpiper to save a child who suffer from breathe
disfunction.

Article 1
Recent research finds that dogs may lose some social smart in the process. A classic experiment about pointing stick is too simple.
Experiemnts 1 illustrates that wolves work together better than dogs do. So the question is dogs may learn well from human, but how about from other dogs?
Experiment 2 illustrates that dogs don't learn from their packs as well as wolves.
Dogs may undergo an evolutionary tradeoff：losing some of the ability to learn from their own kind,but gaining the ablitiy to learn from humans.

Article 2
Immunotherapy drugs will cure above half of cancers and earn a big market: 1.They can cure more kinds of cancers 2. More and more patients will take the drugs 3. The price is stratospheric
Set up one example for proving that Y can cure more kinds of cancers,there's also a new strategy add to the cost.
转：Only some patients respond to Y, so scientists combine another drug,this time the result is much better. But the price will also raise up.
合：Some scientists predict that the price for immunotherapy will not be low even if the drug market expand to other cancers.

Obstacle
A baby boy suffered from breathing problem. The principle of breath using tracha. Introduce standard way to solve the breath problem.
But sometimes the issues are severe,so the scientist turn to 3-d printing.
Illustrate how the technology-3D printed device is used and the advantage of this approach.
The further meaning of this approach.
