The projected Stem cells are produced from adult cells, adding four different types of genes that are normally actives in embryonic cells. They are called Induced Pluripotent Stem cell, or IPS. The IPS, like an embryonic cell, can reproduce a lot of times and can transform in other types of cells.The scientists also are trying to produce specific cells to understand how they act and to test new medicines.
This is an example of how the new technology can help the world if its used with wisdom and good intentions.Unfortunately, the humans also create some new destructive technologies, like weapons.We can name The Active Denial system, which is a weapon that fires rays and these rays, when in contact with the human skin causes an insufferable ardor.
Another example is the Sticky Foam, which is a foam that hards in contact with the air and glue the people onto the floor. The problem is that when this foam is threw at the human face, the person can die of suffocation.
Now we can see that things can be useful for good and bad things. And is our function to decide this use. So, let's be conscious and let`s make an better world with the our technologies!
