7 Scientic Question ?

According to British reports, along with the development of technology and social progress of society, people have a deeper knowledge of the nature of a large number of happenings. But on some other matter until now, scientists still have not been able to provide answers and explanations. Such as:

Do dogs have a sense of humor?

Scientists researching animal intelligence, they increasingly recognize such a view: the behavior of the animals rather than just react instinctively, but an unconscious reaction, a substance thought to make them have the ability to feel love, anger, sadness and joy and even a sense of humor through the sensor organ.

For example, researchers have found that elephants can recognize themselves in mirrors (lots of kids who may not be able to do it this way) orangutan (or perhaps some birds) can learn a number of beginning-level language and create a complicated equipment.

It is conceivable, if a bird can make a hook (hooks) with an electric wire, for use of canned food hook, then is not so cruel when using them as a torture test?

 Is the inner reaction is just nonsense?

Most scientists say do not believe the abnormal phenomenon, because these phenomena are normal and do not violate the principle can be explained by the experiment. But if we can say that crystal therapy (using the crystal energy to "magnetic field organisms' body back in a" balanced "and the inner reaction that is crap?)"Abnormal phenomena" includes the power of Gamma (?), "Spiritual", the chatter of a new era (new century), astrology, divination cards / tarot, scientists have reason assume that the abnormal phenomenon is a pseudo science. But scientists on the contrary, they are careful and rational in science, often publish their latest research findings in leading journal Science. "
But when the crystal therapy and the technique is believed horoscope for entertainment only and not a science, then what about the inner reaction, acupuncture therapy and hypnosis techniques? This remains to be investigated scientifically. And of course, the inner reaction may also be proved as a bird news, who knows? no matter what the outcome, should try to find the real facts.

 What about the origins of life?

If you want to make a biologist, you simply ask what the origin of life. Since 150 years ago, Darwin continued to think and he thinks that all life on Earth comes from the "prebiotic soup". But until now, we're still thinking about the origins 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 begins, and whether life begins from life to death took place only once or repeatedly, and so on.

Some scientists suspect that life originated in the basement, or around the lip of the volcano eruption. Were other scientists suspect, that a single microbe was the ancestor of all living things on earth. At approximately 3 billion years ago, the planet Mars when it's warm and humid, while the earth is only a cold desert, single microbes are flying into the earth along with the explosion of rock debris on the planet 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, it is likely the most mysterious is the mystery in the universe.

What time is it?
If you want to make a physicist, ask him: "What is time? 'Cause, we will not know the answer.There is a rumor that said, time is a magical weapon that blocks the natural activity of all objects simultaneously. Time can define our lives, because we rely on to measure the life time. But in terms of what time it is, we just like the ancients, also did not know anything. And of course, this does not mean we do not know what he has done time. Physicists like Einstain, in which case the characteristics of the view that the time had. So we can provide a sign at the time, and enter into the equation of time is not the same, and thus we can examine a large number of phenomena and draw conclusions.
However, this has not been able to tell us exactly what time it is. Is it a "river" flowing from the past into the future? if yes, then the river is it? What drove the move and on what the current speed of the river flowing? if time is a river, is able to flow upward through this river? and whether we can completely stop the flow of this river flowing?
This allows the fiction novelist said. What amazes us is, physicists also think like this. But before we create a time machine, we should know very well against a difficult time at the touch and easy to disappear in this glance. Until the last day, we will uncover the mysteries of this mysterious. But if so, then it certainly would appear even more mystery. Perhaps the only consolation is decent, if someday we can reveal all mysteries, and if it is really solved, then everything would be tasteless


5. Why obesity is of increasing day by day?

At 100 years ago, the world's hardly a single case of obesity, for 100 years, obesity has become a crisis that no 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. One rarely knows, in a large number of states "obesity" in the west, such as the United States, the heat dissipated people far less heat than those who spent the past 50 years. Compared with those in 1950 ago, we rarely walk, the place is the large number of motor vehicles. Obesity began to flourish since 1980, compared to when it is, sports are much less done.
A large number of scientists believe that the proliferation of obesity must be hidden behind 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? might be, maybe not. Preventing aging is one thing that most do not like to talk to scientists, because this can cause a series of problems such as moral and logic or the things that a real headache.
First, in reality we do not know what exactly it is aging. In our view, when we are old, or the physical body itself will also take old. But the reality is not so. First 20 years of age our lives, our physical from day to day and contains a strong, our bodily functions more effective the more days we are, the stronger the ability to fight disease. However, why in the following days (older), it becomes very opposite?
According to evolutionary theory of aging, why is the function of our bodies begin to age is estimated at 30-50 years old men will die from cold, hunger and death in the wild tiger's mouth and so on. But if we can not live so long, we do not need evolution, to face the pain of old age. But this can not explain, where when we get old, what changes have changed the "clock" genes, so that makes our skin becomes dry, white hair, bones become brittle. 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 that human beings will not be old forever? or in other words, are we really willing to live in a world like that if only a small number of elite people who are lucky to enjoy the new treatment of this young?

7. A minute ago I do the same with me now?

"Do I still like 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 of identity recognition. On the surface, the answer clearly is: "certainly, I was the same person at the last minute. But try to think for a moment longer. "
10 minutes ago, all the things that every cell in your brain is totally different from the things that your brain cells right now. Every few years later, your body is almost completely changed once. Whether Cutty Sark can be re-created with new wood and a variety of new components, would be exactly the same as the Cutty Sark sailing on the sea in the past 150 years? To this, refining the theory answers is: "No". That way, you are no longer your childhood was. This question suggests, that our consideration of the individual is always in contradiction with the real atmosphere is going on. And how do we recognize the identity of the same person, whether based on DNA or something else that is more vague again?
