1. Do dogs have a sense of humor?
Scientists examined the intelligence of animals, they increasingly recognize such a view: the behavior of animals is not just reactinstinctively, but a subconscious reaction, the substance of their thinking makes it have the ability to feel love, anger, sadness and joyand even a sense of humor through sensory organs.
For example researchers have found, that elephants can recognizethemselves in mirrors (many children who may not be able to do it this way) the orang-utan (or maybe some birds) can learn a number of beginning-level language and makes a complicated equipment.
It is conceivable, if the birds can make a hook (hook) with an electricwire, for use hook food from cans, then is not so cruel when using them as an experiment that torture?
2. how the origin of life
if you want to make a biologist, you simply ask what the origin of life.Since 150 years ago, Darwin was thinking and he thinks that all life on earth originated from the "prebiotic soup". But until now, we are still thinking about the origin of life.
We do not know the range of knowledge related to the origin of life,such as how the first, where and when life began, and what is lifefrom life to death took place only once or repeatedly, and so on.
Some scientists suspect that life came from underground, or around the lip of the volcano bursts. Medium other scientists suspect, that a single microbe is an ancestor of all living things on earth. At about 3 billion years ago, when Mars was warm and moist, while Earth is only a cold desert, this single microbes fly to earth along with thedestruction explosion rocks on Mars. According to this view, means that we are all human beings from the planet Mars.
But until now, all these allegations have never been substantiated.So it can not convince anyone. The origin of life, most likely is the most enigmatic mysteries of the universe.
3. Is the inner reaction is just nonsense?
Most scientists say do not believe in an abnormal phenomenon,because these phenomena are normal and not violate the principlecan be explained by the experiment. But if we can say that crystal therapy (using energy crystals to "Magnetic Field organism" human body back in a state of "balanced" and the inner reaction that is crap?).
"The phenomenon of abnormal" include the strength of gamma (?),"Spiritual", the chatter of a new era (new century), horoscopes,divination cards / tarot, scientists have reason assume that theabnormal phenomenon is a pseudo science.
But scientists on the contrary, they are careful and rational in scholarship, often publish their latest research findings in Science magazine prominent. But when the crystal therapy and techniqueshoroscopes believed to be only as an entertainment and not a science, then what about the inner reaction, acupuncture therapyand hypnosis techniques? It remains to be investigated scientifically.And of course, the inner reaction may also be evidenced as a birdnews, who knows? no matter what the outcome, must try to find the real facts.
4. what Time is it
If you want to make a physicist, asked him: "What is time?"Because, we will not know the answer.
There is a rumor that said, time is a magical weapon that blocks thenatural activity of all objects simultaneously. Time can define our lives, because we rely on time to measure life. But in terms of what it is time, we just like the ancients, also did not know anything.
And of course, this does not mean we do not know what has beendone time. Physicists like Einstain, in which case the characteristicsof the view that the time had. So we can give a sign at the time, thenenter the time into the equation are not equal, and thus we canexamine a large number of phenomena and draw conclusions.
However, this can not yet tell us exactly what time. Is it a "river" that flows from the past into the future? if yes, then the river is it? What drove her to move and based on what speed the flow of the riverflowing? if time is a river, whether it can flow upward through this river? and whether we can completely stop the flow of this riverflowing?
5. Why is obesity increasing from day to day increase?
At 100 years ago, the world's hardly a single case of obesity, for 100years, obesity has become an unparalleled crisis unmatched in the history of human disease. If calculated according to the current situation, we will increasingly overweight.
Because obesity is very clear: eating too much, lack of exercise. But the condition is not as simple as this. First they rarely know, in a large number of states "obesity" in the west, such as the UnitedStates, which disposed of calories people far less heat than is spenton people 50 years ago. Compared with those in 1950 ago, werarely walk, the place is the large number of motor vehicles.
Obesity began to flourish since 1980, compared to when it is, sportsis much less done.
A large number of scientists are convinced, that behind the proliferation of obesity must be buried a deep mystery. Some scientists have said that obesity may be caused by a virus, or can be explained by genetics.
6. Whether humans can stay young?
What can we stay young? possibly can, maybe not. Prevent aging is one thing that most do not like to talk to scientists, because this can cause a series of issues such as morality and logic, or the things that a real headache.
First, in reality we do not know what aging actually is. In our view,when we are old, or the physical body itself will also take old. But in reality it is not. First 20 years of age our lives, our physical day by day more and more contained and powerful, the function of our bodies we are more and more effective, more powerful disease-fighting capabilities. However, why in the days that followed (age increases), it becomes very opposite?
According to evolutionary theory of aging, why does our body functions begin to experience aging is estimated at 30-50 years of age men will die from cold, hunger and death in wild tiger's mouthand so on. But if we can not live so long, we did not need evolution,to face the pain of old age. But this can not explain, where when weget old, what changes have changed the "bell" gene, so that makesour skin becomes dry, the hair becomes white, bones becomebrittle. Only after we know exactly what causes this change allows to take new measures against aging.
But we will face a moral issue: are we willing to live in a world inwhich human beings would not be old forever? or in other words, are we really willing to live in a world like that if only a small number ofelite people who are lucky just to enjoy the treatment of this young?

7. A minute ago I do the same with me now?
"Am I still the same as a minute ago?" This sounds like a very strange question! But this is one of the most frustrating problem in the whole world of science and philosophy. That is a matter ofrecognition of identity. On the surface, the answer clearly is: "sure, Iwas the same person in a minute ago.
But try to think back for a moment ", 10 minutes ago, all the things that every cell in your brain is totally different from the things that your brain cells now. Every few years later, your body is almostcompletely replaced once.
Does Cutty Sark can be re-created with new wood and a variety ofnew components, would be exactly the same as the Cutty Sarksailing over the sea at 150 years ago is it? To this, refining the theory answers is: "No". That way, you are no longer your child'sfuture. This question suggests, that our consideration of theindividual is always in contradiction with the real atmosphere going.And how do we recognize the identity of one same person, whetherbased on DNA or other something more nebulous again?
