Something that’s alive you mean? Ooo, that’s tricky. I think scientists have gone as far combining different types of DNA inside bacteria to create a sort of ‘alien’ bacteria which can then reproduce This is still a looooong way from a whole new living thing though. Another approach would be to look at artificial intelligence – creating a computer which displays the same intelligence as a human and thinks in the same way. Whether or not it’s a living thing is an interesting question in itself – if you can’t tell the difference between an AI and a human then can you say it’s alive?
I would say similar to Camilla, depends what you mean by ‘living thing’. If its something that follows MRS GREN (Moves, Respires, Senses, Grows, Reproduces, Excretes and Nutrition) then we are a long way off from that. If rather you mean something that can think independently and act as a human, then AI might not be too far off!
