Science and technology plays an important role in people’s daily life. If you compare the life of people today with that in the past, it is easy to see that science and technology have done a great deal to improve the quality of people’s life. For example, computers have become our good friends; with the help of computers, people all over the world are able to share the information on the net, which shortens the distance between them. It’s true of science, such as octapeptide 2.
1. Will concert help the postoperative rehabilitation of patients?
Scientists have found that music can help relieve the pain and fear of patients after surgery. The team led by Catherine Meads has published a paper which pointed out listening to music can reduce the desire for patients to have painkillers for the purpose of increasing their satisfaction. However, it does not contribute to shorter hospital stays.
Scientists have studied the impact of music during the surgery and post-operative process, enabling to find a fact that music also has an impact on coma patients.
2. Will mothers keep the children’s DNA after postpartum period?
The answer is “yes”. This phenomenon exists in many mammals, including human beings. Such phenomenon is called fetal micro-chimerism. During the pregnancy, some cells of fetus are transferred to the body of mothers, or even to survive in the body of mothers, as an organ cell.
3. Can beetle really be immune to the extinction?
Actually it’s not, but beetle does have a special resistance to certain substances. It’s estimated that only 35 completely extinct among the existed 214 beetle families for over 300 million years. In fact, beetle is currently the most common species. The powerful resistance of beetle towards extinction is mainly derived from the flexibility to adapt to changing habitats and capabilities, as well as the ability to change the population that survives in different environments.
4. What’s the validity of military food?
In terms of the species, nutritional value and expiration date and other terms, the US military food can be seen as the reference. US forces are using the separately packaged foods, usually valid for up to five years. The product will be tested in order to confirm whether it can be saved to five years in good condition. It will be possible to make it below 27 degrees Celsius. If the temperature is too high, the shelf life will be greatly shortened. If the temperature reaches 37 degrees, the shelf life only remains nine months.
5. Will the nail grow more slowly in winter?
The answer is “yes”. The average growth rate of toenails and fingernails are monthly 1.5 mm and 3 mm. In the coldest season of the year, the growth rate declined slightly, but the scientific community is not clear about the cause. Maybe it’s because of less sunshine time. Such factor will also affect the blood circulation and hair growth.
In brief, we should admit that technology is very useful and important. Without science and technology, man’s life would not be as convenient as today. Science will continuously benefit people’s daily life!
