Developed in the early 2000s, optogenetics—the combined use of genetic and optical (light) methods to control genes and neurons—is among the most rapidly advancing technologies in neuroscience and has the potential to revolutionize how scientists study the brain. With precisely timed pulses of light aimed at targeted tissue regions or cells, optogenetics allows researchers to trigger or block events in specific cells of living animals. In a mouse with a paw made hypersensitive to touch, for instance, the pain response can be eliminated by shining yellow light on the affected paw, cells in which have been targeted to express a type of light-sensitive microbial protein known as opsin.
How do you control your computers today? Most of them, through a keyboard and a mouse. Lots of computers also come with a voice interface, too - most notably smartphones and smart speakers. The next level of ergonomy, in turn, might not require the use of our hands and voices, only our brains - at least this is what many researchers want to achieve. Soon, computers will be able to read our minds, opening up new means of interaction between man and machine.
This robot A.I once said it wanted to destroy humans. Senior correspondent Steve kovach from business insider conducts this remarkable interview. The topic of person A.I. is brought up as a way for humans to expand their intelligence..
In other articles on this site we described a possible virtual society that can exist for people after they have passed from this life. What happens when people that are currently alive how would they interact in virtual Heaven with dead people?
