A new opinion about the dog and wolf. dogs are not trianed by man from wolf, but evoluted from gather society to domestic society.
new evidence show three area's dogs has no obvious relationship from wolves but share a lot of similarities.

The speaking talks about the a study result which demonstrates that brain-training enable people to master a new skill but not make them intelligence.

Brain gets heavier when the mind is at work. This fact was actually first found by an Italian scientist in 1850. Recently, a study group made a further research on it. According to the study, during the first two second of reveiving audio or vedio singnals, the brain becomes a bit lighter by shunting the waste-ridden blood out; seconds after that, new blood flew into the brain and made the brain heavier.                                                       
Time 3 2'01"                                                       
The change in force was very small and it is hard to calculate the volume of blood rushing into the brain. The Italian scientist Moss found that tasks required more mental energy made the brain heavier and strong emotion also tipped the scale. It is good that someone began to find interest in this topic and various research on brain can help us to approximate the complexity of the brain.                                                       
Time 4 3'10"                                                       
If we want to see what a cat see veryday, we can strap a cat-cam to its collar. So why not put a camera on baby; thus we  can know what the world like from the baby's perspective. Study revealed that much of the footage was version of face, while adults are exposed to real faces only 7 to 8 percent of their time.

2  Stopwatch Event - Split:         00:03:00.9
When the brain is at work, it get heavier. This point is not new. A professor along with his students backed up this point with an experiment by measuring the blood pressure in brain

3  Stopwatch Event - Split:         00:02:59.0
The force change is slightly in brain and it is hard to decide how much blood rushes with each mental task. M thought the tasks which required more energy make the brain more heavier. People have ignored M's study manuscripts for a long time. Now scientists usually use balance to measure though it is not a perfect way.

4  Stopwatch Event - Split:         00:02:55.9
Someone put the little cam on various animals to see what the world these animals see. Some guy in a university finally apply this idea on baby. The footage they got revealed a baby's world quite boring with occasional excitements. And they also found that a baby confronts big faces quite longer time than a adult does.

5  Stopwatch Event - Split:         00:02:20.4
Most faces a baby see are family, and mother's face occur most. The chance to see a lot faces practices baby's ability to distinguish faces. But this ability seems to lose when the baby grow older and learn that some certain faces are more important. Then the article lists some other issues a baby-cam can detect.

V got something new and interesting in biology in his two books. He made a life-form with a synthesized genome, and proved that twist and turns are the mark of science.

The dog and wolf were though to evolved from a common ancestor in the past studies. A current study shows that various kinds of dogs may diverged from a common ancestor that is a kind of extinct wolf. This study provides new insights on domestication.

a new study shows that the dog's domestication process is more complicated than originaly thought.  experiment using groups of genomes from dog and wolf demonstrated that dog breeds were most closely related to each other and may have descended from an older, wolf-like ancestor common to both species.  further experiment shows there maybe an exchange in wolves' genes and domestication may had bottlenecks alongside the process. according to the evidneces, scientists paints a complex picture of early domestication.

Brain-training game can improve the player’s intelligence for certain game, but cannot work for other brain area according to an experiment.

1 A brain related theory, that hard working brain is much heavier than the rest one, is now back up by a new similar study.
2 Not only the workload but also people’s motion can influence brain weight, and how well we can measure the change matters most about how well we can approximate the complexity of the brain.
3 The record taken by a tiny camera which is put on the headbands shows a difference between the prospective and adults’ perspective that babies are exposed to a real face more often than adults.
4 Babies are pretty good at discerning a wide variety of faces. Except this, the baby-cam tell nothing else could be detected.
5 Vender’s new book “life of the speed of light”, which includes one story of Synthia regarded as a hallmark of modern science, is notable, especially the part of science as progress.

TIME2 02'25
main idea:a scentist indicates that when brain is thinking,it's weight will be higher. another researcher seted up a experiment to testify to this theory.

TIME3 02'11
main idea:since the changes in newton are so small, the research did not prove whether listening to music or watching TV will definitely lift the weight of one's brain.however,the professor suggests that people who reading scientific or academic papers will tip the balance than those reading newspapers.
the balance will prove useful.

TIME4 02'11
main idea:the passage give us a research on baby.
a researcher puts an tiny camera on newborned babies' head in order to figur out the scence of babies' sight.the study indicates that babies spend approximate quauter of their time in the presence of a human face,while adults are only exposed to real face about 7 or 8times od their real time.

TIME5 01'54
main idea:the majority of the faces encountered to babies are their mothers,old brothers,and actually involved fathers.
babies infantlly are capable of distinguishing faces.however,as growing older,this discernment become weaker.they can distinguish the importance of faces and perceive which are useful and meaningful to them.
in spite of the fact that the baby-cam can capture the faces ,it cannot capture language a baby heared.

TIME6 02'27
main idea:V write a biological book to illustrate the future biological engineering regarding some DNA stuff (like bacterial mash-up).

TIME7 6'34
main idea:recent research regarding the relation of dog and wolve definitely surprise the scientists and break the thought we preciously had about the relation between these two species.
some research demonstrate that rather than dogs from two isolated area share more common in gene,while dogs did not have strong relation to wolves from the same area.dogs and wolves may envolve from a far extincted ancestor,which can explain this suprised found.

time 2 [2'04]
the fact that when brain is working, it will weights heavier. and introduced some further experiencement introduction. the blood moving might influnce the weight.

time 3 [1'39]
another professor furthter says that the blood is not relocate from a to b, but the changes in brain workload

time 4 [1'50]
an observation to the new born baby, in fact they spend much time on presence of a face

time 5 [1'09]
the face in baby's mind is mostly mother, and this process makes them perceive faces better, although when they become older they cannot perceptual tuning
