To become immortal, humans need to stop the aging process of the body. A group of animals may have solved this problem, so it is not as impossible as we often think. Hydras are small, jellyfish-like invertebrates. They use a special method to stop the aging process. Their bodies are made up of stem cells that are constantly dividing to create new cells, while old cells are discarded. This allows the hydra to rejuvenate itself, or in other words stay young forever. "They don't seem to age, so they're likely immortal," said Daniel Martínez, a biology professor at Pomona University in Claremont, California (USA). The hydra's case shows that animals don't necessarily age, but that doesn't mean humans can mimic their rejuvenation process. “The Hydra is only 10mm long and has no organs. But the human body is very complex,” says Martínez. Human cells carry out specific functions, and many cell types are incapable of dividing. As these cells age, so does our body,” said Martínez. What we need to do to stop the aging process is not simply to get rid of our old cells like the hydra, because we need them. For example, nerve cells in the brain are responsible for transmitting information. "We don't want them to be replaced, or we won't remember anything," Martínez said. Hydra could be the inspiration for new research that helps people live healthier lives, by finding ways to help cells function better as they degrade over time. Humans can live beyond their biological limits with future advancements related to nanotechnology. Machines with a size smaller than 100 nanometers can travel through the blood, helping the body prevent aging by repairing cell damage. Nanotechnology also helps treat a number of diseases, including certain types of cancer, by removing cancer cells from the body, according to the University of Melbourne (Australia).

Advantages :))

Science and technology has become a debated topic in the society. On one hand, it is necessary for the modern life where other countries are continuously developing in the field of science and technology. It becomes very necessary for other countries too to grow in the same way to be strong and well developed like other countries for the future safety and security. It is science and technology which helps other weak countries to develop and be strong. We have to take support of science and technology forever to improve the way of life for the betterment of mankind. If we do not take the help of technologies such as computer, internet, electricity, etc we cannot be economically strong in the future and would be backward forever even we cannot survive in such a competitive and technological world.

Advancement in the field of medical, agriculture, education, economy, sports, games, jobs, tourism, etc are the examples of science and technology. All such advancements show us that how both are equally beneficial for our life. We can see a clear difference in our life style while matching the ancient and modern way of life. High level of scientific and technological advancement in the field of medicine has made easy the treatment of various lethal diseases which was earlier not possible. It has helped a lot to the doctors to find effective ways to cure diseases through medicine or operations as well as research vaccines to cure diseases such as cancer, AIDS, diabetes, Alzheimer’s, Leukemia, etc.

Disadvantagesssss :)))

Disadvantages of science not much but technology, yes. Technology has in our lives helped in creating comfort, increasing productivity and connecting more of us with each other. While it has some advantages like I can effortlessly travel between two far away places, do more stuff in a day and talk to my mom and dad over the internet where we are miles away from each other, it has its pitfalls.

First, it has made us move less than we used to. We don't walk much as our ancestors did. We don't lift things to clean, slog and move our muscles to do household chores. This makes one of the greatest problems of the western world - obesity.

Secondly, increased productivity and better refrigeration means increased production of processed foods. Junk foods with high concentrations of sugar and fat. Again a problem that is faced globally and in more in the western world like diabetes, high cholesterol, coronary heart disease. Etc.

Thirdly, connecting more of us with each other. This is a boon and a bane. When you are Connected it's not just you who gets access to the internet but also that the internet has access to you. This can have adverse consequences if not used cautiously like cyber data crimes - e.g. The recent Facebook-Cambridge analytica issue which led to personally identifiable information to be sold without consent to a third party by Facebook.

Finally, it's not just the technology to be really blamed here. It's the abuse of technology like misusing or total reliance on technology for basic tasks that make it a disadvantage.
